In addition, the present invention also provides a kind of product, for the product generated after the molding of colored PC anti-static material.
Compared to the prior art, colored PC anti-static material of the invention can prepare one by the way that antistatic agent is added
It plants wide use temperature range, high-performance and colored PC anti-static material can be contaminated.
[specific embodiment]
Colored PC anti-static material of the invention, indicates in parts by weight, comprising:
95-99 parts of PC resin, the PC resin is bisphenol A polycarbonate, polyester-type polycarbonate, hexamethylene bisphenol-A
At least one of type polycarbonate, polycarbonate of bis-phenol TMC synthesis, in 300 DEG C of temperature, weight bearing 1.2Kg, the PC's
Melt mass flow rate is between 3-50g/10min；Wherein, it in order to increase the use temperature range of PC resin, especially mentions
Notched impact properties at low temperature is risen, relative to the colored PC anti-static material of 100 parts by weight, adds organosilicon copolymerization PC's
Parts by weight are at least 30 parts, thus it enables that colour PC anti-static material is greater than 40KJ/ in -30 DEG C of notch impact strength
m2, further, polydimethylsiloxane content is further promoted and is lacked between 10%-50% in the organosilicon copolymerization PC
Mouth impact strength.
1-5 parts of antistatic agent, the antistatic agent is ethoxylated alkylamine, ethyoxyl lauramide, monoglyceride, height
Grade at least one of alcohol sulfuric ester salt, the antistatic agent not only make PC resin become anti-static material, and make PC resin at
For colored PC anti-static material can be contaminated.
Wherein, in order to guarantee the sustainability of antistatic effect, the colour PC anti-static material further includes polyvinyl alcohol
Or methoxy poly (ethylene glycol)-methacrylate copolymer, preferably with PC resin compatibility, in 90 DEG C of 60 days degradations
In, the resistance of the colour PC anti-static material can reduce to 10^9Ohm (10 9 power ohms), can reach long-term dimension
Hold the effect in 10^8Ohm~10^10Ohm.
Wherein, functional composite material in order to obtain, under the premise of not influencing functional effect, the colour PC is antistatic
Material further includes at least one of anti-dripping agent, antibacterial agent, ultraviolet absorbing agent and release agent.
To have further understanding to the purpose of the present invention, effect and technological means, now in conjunction with comparative example and specific implementation
Example is described as follows.
Embodiment 1
Wherein, PC resin 1 is the PC resin other than organosilicon is copolymerized PC, and PC resin 2 is that organosilicon is copolymerized PC resin.
Weigh each component of corresponding weight；Then, each component is stirred using uniaxial agitator；Said mixture is added separately to double
Melting extrusion is granulated in screw extruder.
Embodiment 2
Wherein, PC resin 1 is the PC resin other than organosilicon is copolymerized PC, and PC resin 2 is that organosilicon is copolymerized PC resin.
Weigh each component of corresponding weight；Then, each component is stirred using uniaxial agitator；Said mixture is added separately to double
Melting extrusion is granulated in screw extruder.
Comparative example 1
1 70 parts of PC resin；
2 30 parts of PC resin.
Wherein, PC resin 1 is the PC resin other than organosilicon is copolymerized PC, and PC resin 2 is that organosilicon is copolymerized PC resin.
Weigh each component of corresponding weight；Then, each component is stirred using uniaxial agitator；Said mixture is added separately to double
Melting extrusion is granulated in screw extruder.
Comparative example 2
Wherein, PC resin 1 is the PC resin other than organosilicon is copolymerized PC, and PC resin 2 is that organosilicon is copolymerized PC resin.
Weigh each component of corresponding weight；Then, each component is stirred using uniaxial agitator；Said mixture is added separately to double
Melting extrusion is granulated in screw extruder.
Comparative example 3
1 98.7 parts of PC resin；
0.3 part of ethyoxyl lauramide；
1 part of methoxy poly (ethylene glycol)-methacrylate copolymer.
Wherein, PC resin 1 is the PC resin other than organosilicon is copolymerized PC.Weigh each component of corresponding weight；Then,
Each component is stirred using uniaxial agitator；Said mixture is added separately to melting extrusion in double screw extruder to be granulated.
After the above various embodiments and comparative example melting extrusion are granulated, then the particle in each embodiment is infused on injection molding machine
It is moulded into type standard testing batten, by the mechanical performance of standard testing resulting materials, test result is as shown in table 1:
Table 1: the test result of each embodiment and comparative example
Wherein, according to the color of CIE1976LAB colour difference formula test resulting materials in the position of the colour space are as follows: lightness L is
Between 25%~98%, green-A value is between -30~40, and yellow B value is between -40~70, therefore the material can be adjusted
Change appearance with color matching for random color, is passed through.
It can be learnt by upper table: by embodiment 1 compared with comparative example 1, it can be seen that addition antistatic agent and methoxyl group are poly-
After ethylene glycol-methacrylate copolymer, the surface resistivity of material is reduced very much, and correspondingly antistatic property obtains very big
The promotion of degree, by embodiment 1 compared with comparative example 2, the rushing under impact strength and low temperature after being added to titanium dioxide of comparative example 2
Hit intensity is nothing like in embodiment 1, therefore the material in embodiment 1 does not need addition titanium dioxide；By embodiment 2 and comparison
Example 3 is compared, and organosilicon copolymerization PC is not added in comparative example 3, the impact strength of material is low well below in embodiment 2 at low temperature
Impact strength under temperature, therefore visible addition organosilicon copolymerization PC is able to ascend notched impact properties at low temperature, increases material
The use temperature range of material.
In addition, the present invention also provides a kind of product, for the product generated after the molding of colored PC anti-static material, the production
Product can be widely applied in electron and electrician product, such as apply in the fields such as printer, appliance shell or signal wire joint.
