Description

  The present invention relates to an antistatic polymer and its use.

  From the viewpoint of high processability, light weight, and variety of materials, resin has become one of the materials that are indispensable in modern times. The general property is high insulation. Utilizing this characteristic, resins have been used as insulating sites for many electronic products and electronic parts. On the other hand, because of its high insulating property, it has a problem that it is easily charged by friction and peeling.

  Not only dust and debris adhere to the charged resin molding, but when applied to electronic products and electronic components, it may adversely affect the internal circuits, transistors, ICs, CPUs, etc., and may damage them. is there. In addition, there is a possibility of causing an explosion in places where electric shock is given to the human body or where flammable gas or dust is handled. Also, in clean rooms and medical institutions, dust and dust are disliked, so an interior material with antistatic performance is required.

  In the field of electronic materials used for electronic products and electronic parts, contamination by alkali metal ions such as sodium ions and potassium ions and alkaline earth metal ions is regarded as a problem. When these ions are mixed in the electronic material, not only the function of the electronic product or the electronic component is deteriorated or destroyed, but also there is a risk of heat generation, ignition, and explosion due to these. From such a point of view, it is desirable that materials applied to electronic products and electronic parts do not contain metal ions.

  In order to solve these problems, the resin is often treated with an antistatic agent. Treatment with an antistatic agent is roughly divided into surface treatment and internal treatment depending on how it is used.

  In the surface treatment, an antistatic agent is applied to the surface of a resin molding using a technique such as application, immersion, or spraying. A typical example is a water-soluble surfactant, but it has a drawback that its antistatic ability decreases with time.

  The internal treatment is a technique of adding an antistatic agent to the polymer during resin molding. Representative antistatic agents in this technique include conductive fine particles and surfactants.

  Examples of the conductive fine particles include metal powder, metal oxide fine particles such as ITO and ATO, and carbon. However, in order to impart antistatic ability to the resin using these materials, a considerable amount is not added. In addition, advanced technology is required to uniformly disperse them. Further, due to the large amount of addition, the original physical properties of the resin are greatly affected.

  Furthermore, many metal oxide fine particles contain metals such as antimony and indium. Among them, heavy metals such as antimony have a big problem at the time of disposal, and there are concerns about human health and environmental safety. Furthermore, noble metals such as indium have problems of depletion and high price.

 Surfactants include anionic, cationic, and nonionic surfactants that are added in an amount of 0.5 to 5%, and are inexpensive and are used in various applications. However, they have a problem that they ooze out from the resin surface (bleed out) and contaminate the surroundings. In addition, anionic systems lack compatibility with polymers, are difficult to disperse uniformly, and have low heat resistance. Cationic systems have no problem with antistatic properties, but have low thermal stability. Has characteristics such as low compatibility with polymers.

  Furthermore, in these materials, the influence on the performance by the surrounding environment is large. In particular, it is said that the influence of humidity is great. In general, the antistatic effect is exhibited under high humidity conditions, but when the humidity is low, the effect diminishes and eventually may not function at all.

  When combined with a highly transparent resin, the antistatic agent is also required to have high transparency so as not to lose its characteristics. Even if it is an application that does not require much transparency, it is desired that the transparency is high due to problems in design and the like.

  There is a demand for an antistatic agent having not only the original function as an antistatic agent, but also transparency, solubility in a resin or solvent (compatibility), and heat resistance.

 Furthermore, when a metal filler is used to provide an antistatic function, noble metals or heavy metals may be used. Precious metals are concerned about the problem of depletion of their resources and are expensive. As for heavy metals, there are big problems at the time of disposal, and there are concerns about safety to the human body. Therefore, a material containing no precious metal or heavy metal is desired.

 In the field of electronic products and electronic materials, contamination by alkali metal ions such as sodium ions and potassium ions and alkaline earth metal ions is regarded as a problem. When these ions are mixed in an electronic material or the like, not only the functions of the ions are deteriorated or destroyed, but also there is a risk of heat generation, ignition, and explosion due to the functions. From such a point of view, it is desirable that materials applied to electronic products and electronic parts do not contain metal ions.

 The compatibility between the antistatic agent and the resin is the largest factor affecting the migration rate of the antistatic agent to the surface. The better this compatibility is, the easier it is to knead into the resin, but the migration to the surface becomes worse, and even if it has an inherently excellent effect, its antistatic effect is reduced. On the other hand, if the compatibility is poor, the migration speed of the antistatic agent to the surface is too large and bleed out, resulting in surface stickiness and design problems. That is, it is necessary to select an antistatic agent according to the target resin.

  Accordingly, the object of the present invention is to solve these problems, that is, not only high antistatic ability, but also transparency, solubility in resin and solvent (compatibility), heat resistance and moisture resistance, An object of the present invention is to provide an antistatic agent that is prevented from being out, contains no metal or metal ion, and requires a small amount of addition. Another object of the present invention is to provide a resin composition, a resin varnish, a polymerizable composition, a coating liquid using the antistatic agent, and a method for producing a resin shaped article having antistatic ability using these. It is to provide. Furthermore, the other object of this invention is to provide the resin molded article which has antistatic ability.

  By shaping the kneaded resin composition into an arbitrary shape, a resin shaped product having antistatic ability can be produced.

  The antistatic polymer of this invention can also be mix | blended with resin and a solvent, and can also be used as a resin varnish. In this case, the above-mentioned resins can be used as the resin.

Commonly used solvents include methyl ethyl ketone (MEK), dimethylformamide (DMF), N-methylpyrrolidone (NMP), methoxypropanol, toluene, water and the like. Further, these solvents can be arbitrarily used alone or in combination of two or more.

  For example, a resin shaped article having an antistatic ability can also be produced by applying the resin varnish on an appropriate support and drying it.

  Drying and curing of the applied resin varnish is appropriately selected depending on the solvent to be combined and can be dried at room temperature, but usually it is often performed using a heating and drying furnace. The drying furnace is preferably filled with air, an inert gas (nitrogen, argon, etc.), or the inert gas is preferably flowed into the drying furnace. The drying and curing temperatures are appropriately selected according to the boiling point of the solvent, but are preferably in the range of 60 ° C to 600 ° C. In addition, it is preferable to raise the temperature stepwise because a molded resin product having a uniform film thickness and excellent dimensional stability can be obtained without causing problems such as foaming and crushed skin. The drying and curing time is appropriately selected depending on the thickness of the resin molded product to be formed, the solid content concentration of the resin varnish, and the type of the solvent, and is preferably about 0.05 to 500 minutes.

  In the resin composition and the resin varnish, the amount of the antistatic polymer added to the resin is not particularly limited. However, if blended in a large amount, it may affect the original physical properties of the resin, such as a decrease in physical properties such as mechanical strength, and if the blended amount is small, the antistatic effect may be insufficient. Therefore, the preferable blending amount is 0.01 to 30% by weight, more preferably 0.02 to 25% by weight, and most preferably 0.02 to 20% by weight based on the resin.

  Next, a method for forming a coating film of an antistatic polymer on the surface of the shaped resin will be described. In forming the coating film, a coating liquid containing an antistatic polymer and a solvent can be used in addition to the resin composition and the resin varnish.

  For example, when using a coating liquid, as a coating method for forming a coating film on the surface of the shaped resin, a solution, dispersion, or emulsion containing the antistatic polymer according to the present invention may be dipped, spin-coated, sprayed.

Example 1
As a UV curable monomer, 1.5 g of purple light UV1700B (manufactured by Nippon Synthetic Chemical Co., Ltd.), as a polymerization initiator, 0.15 g of DidoCure 174 (manufactured by Daido Kasei), and 3 g of PGME (propylene glycol monomethyl ether) as a diluent solvent As an antistatic agent, 0.03 g of compound (1) (resin ratio: 2% by weight) was weighed and mixed, and stirred so that the mixed solution became uniform.

Using the bar coater # 12, the mixed solution was applied onto a PET substrate to form a coating film, and then dried at 100 ° C. for 1 minute. The film was cured by light irradiation (640 mW / cm ² ) using a metal halide lamp. The antistatic ability was evaluated by measuring the surface resistance value of the cured coating film (R8340A manufactured by Advantest Corporation). Thereafter, the surface resistance value (Ω / □) is a value of 10 ¹⁰ units or less, ◎, 10 ^11th power level Ω / □, ◯, 10 ^12th power level Ω / □, △, 10 ^13th power level Ω The value of / □ is indicated by ▽, and the 10 ^13th power or more is indicated by ×. Moreover, it measured also about the total light transmittance (Huga-2B by Suga Test Instruments Co., Ltd.) of the cured coating film.

Further, bleed out was evaluated by a moisture resistance test. That is, after leaving the sample for 10 days under the conditions of 40 ° C. and 95% RH, the appearance of the coating film was visually observed and compared with the coating film appearance immediately after curing, and evaluated in the following three stages;
A: No change
○: Slightly bleed material is observed, but appearance is good.
Moreover, the change of the contact angle of the coating-film surface by bleed-out was observed, and compared with the coating film immediately after hardening, it evaluated in the following two steps.
A: Change of less than ± 1 degree,
X: Change of ± 1 degree or more.

Example 2 to Example 42
The surface resistance value of the cured coating film was measured in the same manner as in Example 1 except that the compound (2) to the compound (42) were used instead of the compound (1).

Examples 43-84
The surface resistance values of the cured coating films were measured in the same manner as in Examples 1 to 80 except that 0.075 g (resin ratio 5 wt%) of compound (1) to compound (80) was used.

Comparative Example 1
The surface resistance value of the cured coating film was measured in the same manner as in Example 1 except that the commercially available antistatic agent Sanconol A400-50R (manufactured by Sanko Chemical Co., Ltd.) was used instead of the compound (1).

Comparative Example 2
The surface resistance value of the cured coating film was measured in the same manner as in Example 43 except that the commercially available antistatic agent Sanconol A400-50R (manufactured by Sanko Chemical Co., Ltd.) was used instead of the compound (1).

Comparative Example 3
The surface resistance value of the cured coating film was measured in the same manner as in Example 1 except that the commercially available antistatic agent Cotamine 24P (manufactured by Kao Corporation) was used instead of the compound (1).

Comparative Example 4
The surface resistance value of the cured coating film was measured in the same manner as in Example 43 except that the commercially available antistatic agent Cotamine 24P (manufactured by Kao Corporation) was used instead of the compound (1).

  Table 1 shows the results of Examples 1 to 84 and Comparative Examples 1 to 4.

Table 1

  When the antistatic polymer of the present invention was used, a sufficient antistatic effect was obtained regardless of the amount added. Furthermore, even when the values of 2% by weight and 5% by weight were compared, there was no significant difference, and even a small amount was sufficiently effective.

  The total light transmittance of the PET film of the substrate was 89.80%, and when the antistatic polymer of the present invention was used, it showed almost the same value. The antistatic agent of the present invention is a highly transparent material. Moreover, in Comparative Example 3 and Comparative Example 4, the coating film was observed due to the low compatibility of the antistatic agent. The total light transmittance showed a low value because the scattering component by them increased.

  When the antistatic polymer of the present invention was used, there was no change in the appearance of the coating film even after the moisture resistance test, and no significant change in the contact angle was observed. In Comparative Examples 1 to 4 which were tested with a general-purpose antistatic agent, the appearance was damaged and the surface was sticky due to bleeding out after the moisture resistance test. Further, the contact angle was greatly changed immediately after the coating film.

Example 85
100 g of high-density polyethylene (manufactured by Aldrich) and 3 g of compound (1) were kneaded at 150 ° C. for 5 hours using a kneader manufactured by Inoue Seisakusho. Further, the kneaded product was extruded using an extrusion molding machine to form a resin plate having a thickness of 5 mm. Table 2 shows the results of measuring the surface resistance of the resin plate as an evaluation of the antistatic ability. Moreover, the presence or absence of discoloration of the resin plate was also evaluated.

Example 86 to Example 126
The surface resistance value of the resin plate was measured in the same manner as in Example 85 except that the compounds listed in Table 2 were used instead of the compound (1). The results are shown in Table 2. Moreover, the presence or absence of discoloration of the resin plate was also evaluated.

Comparative Example 5

The results are shown in Table 2. Moreover, the presence or absence of discoloration of the resin plate was also evaluated.

Comparative Example 6
The surface resistance value of the resin plate was measured in the same manner as in Example 85 except that the commercially available antistatic agent Dasper 125B (manufactured by Miyoshi Resin Co., Ltd.) was used instead of the compound (1). The results are shown in Table 2. Moreover, the presence or absence of discoloration of the resin plate was also evaluated.

Comparative Example 7
The surface resistance value of the resin plate was measured in the same manner as in Example 85 except that the commercially available antistatic agent Emulgen 105 (manufactured by Kao Corporation) was used instead of the compound (1). The results are shown in Table 2. Moreover, the presence or absence of discoloration of the resin plate was also evaluated.

Table 2

  As can be seen from the results of Examples 85 to 126, even when the antistatic polymer of the present invention was kneaded with a thermoplastic resin at a high temperature of 150 ° C. for 5 hours, a high antistatic effect was obtained. Furthermore, no yellowing was observed in the resin plate using the antistatic agent of the present invention.

  On the other hand, in Comparative Examples 5 to 7 which were tested with a general-purpose antistatic agent, antistatic ability could not be expected, and yellowing was also observed due to kneading at high temperature for a long time. In particular, in Comparative Example 5, an unpleasant odor was felt. Gas chromatographic analysis confirmed the odor caused by pyridine, which is a constituent of the antistatic agent.

Example 127
0.5 g of compound (1) was dissolved in 10 g of PGME (propylene glycol monomethyl ether), and the solution was applied onto a 100 μm PET film using a spin coater and dried at 80 ° C. for 1 minute to form a coating film. Table 3 shows the results of measuring the surface resistance value of the coating film as an evaluation of the antistatic ability.

Example 128 to Example 168
The surface resistance value of the coating film was measured in the same manner as in Example 127 except that the compounds listed in Table 3 were used instead of the compound (1). The results are shown in Table 3.

Comparative Example 8
The surface resistance value of the coating film was measured in the same manner as in Example 127 except that the commercially available antistatic agent dodecylpyridinium chloride (DPC: manufactured by Tokyo Chemical Industry Co., Ltd.) was used instead of the compound (1). The results are shown in Table 3.

Comparative Example 9
The surface resistance value of the coating film was measured in the same manner as in Example 127 except that the commercially available antistatic agent Dasper 125B (manufactured by Miyoshi Resin Co., Ltd.) was used instead of the compound (1). The results are shown in Table 3.

Table 3

  As is clear from the results in Table 3, the antistatic polymer of the present invention exhibited a lower surface resistance value than a general-purpose antistatic agent.

Example 169
A mixture of 1 g of compound (1) and 10 g of ethyl acetate and stirred was applied on a glass substrate using a spin coater to form a coating film, and then dried at 100 ° C. for 1 minute. The surface resistance value of the coating film was measured by changing the humidity conditions. The results are shown in Table 4.

Example 170 to Example 210, Comparative Example 10 to Comparative Example 12
Surface resistance values were measured in the same manner as in Example 169 except that the compounds shown in Table 4 were used instead of the compound (1). The results are shown in Table 4.

Table 4

The antistatic polymer of the present invention shown in Table 4 hardly changed its surface resistance value even when the humidity was changed. However, in the compound shown in the comparative example, the surface resistance value increased by an order of magnitude under the humidity of 55% RH. Further, as the humidity decreased, the surface resistance value increased, and at 35% RH, the value became 10 ¹⁴ Ω / □ or more, and the antistatic effect was lost. Since many of the compounds shown in the comparative examples have high solubility in water, it can be assumed that the influence of humidity is large.

  Judging comprehensively from these examples, the antistatic polymer comprising a combination of a specific cation and a specific anion of the present invention has not only high antistatic ability, but also transparency and solubility in a resin and a solvent ( (Compatibility), heat resistance, moisture resistance, bleed-out was suppressed, and noble metals, heavy metals, and metal ions were not included. The antistatic agent of the present invention exhibits excellent antistatic ability particularly in an environment with low humidity.
