Description
Technical field
The present invention relates to technical field of chemistry and chemical engineering, especially a kind of melt pressure sensitive gluing agent.
Background technology
At present, traditional solvent pressure-sensitive adhesive is long for drying time, price is high, and serious environment pollution in work progress, the health of harm workmen, therefore, more common tackifier resins includes with Petropols, terpene resin, the synthetic materials such as polyester resin are viscosifier, but polyamide and polyester resin are complex due to production technology, domestic Shen Shao producer relates to this field, and terpene resin raw material based on Oleum Terebinthinae, higher being not suitable for uses price in a large number, it is most widely used with Petropols at present, owing to oil is non-renewable resources, along with supply is fewer and feweri, the situation that supply falls short of demand is inevitable.
Summary of the invention
The invention provides a kind of melt pressure sensitive gluing agent, it can solve the high problem serious with environmental pollution of cost that existing melt pressure sensitive gluing agent uses Petropols to bring as raw materials for production.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
Include the compositions of following weight portion:
Light color liquid resin 30～40 parts；Styrene-second diene block copolymer 90-100 part；Mixed type plasticizer 4-5 part；Antioxidant N-dibutylamino dithiocarbonic acid zinc 2-5 part, filler 9-10 part.
The preparation method of above-mentioned light color liquid resin is:
A, resin and fumaric acid being reacted through diene synthesis and prepare fumaric acid modified resin, reaction temperature is 200 DEG C～210 DEG C, and the response time is 1～2 hour；Described fumaric acid accounts for the 1.5%～2% of described resin gross mass；
B, addition diglycol carry out pet reaction, introduce straight chain group long chain acid in pet reaction process, and reaction temperature is 250 DEG C～260 DEG C, and the response time is 2～3 hours, obtains semisolid rosin ester；Described diglycol accounts for the 11%～12% of described resin gross mass, and described straight chain group long chain acid accounts for the 0.5%～1% of described resin gross mass；
C, while pet reaction add antioxidant, reaction temperature is 263～267 DEG C, and the response time is 55 minutes～60 minutes, it is ensured that rosin resin color stability is at no more than No. 5 colors, and described antioxidant accounts for the 0.1% of described resin；
D, introducing mineral oil and mix at normal temperatures with the semisolid rosin ester of step B gained and dissolve each other, the response time is 2～3 hours, i.e. obtains this light color liquid resin, and described mineral oil accounts for the 20%～30% of described resin gross mass；
Wherein, described straight chain group long chain acid is butanoic acid；
Described antioxidant is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propanoic acid] pentaerythritol ester.
Owing to using technique scheme, there is advantages that
1, the light color liquid resin owing to using in the present invention is as basic production raw material by Renewable resource Colophonium, it is esterified by modification and adds mineral oil and changed into liquid state, not only solve domestic petroleum resin price high, the shortcoming that raw material is non-renewable, also reduce the usage amount of softening agent and viscosity-controlling agent, more cost-effective.
2, the preparation process of the liquid resin of the present invention is easily controlled, non-pollutant discharge can be fully achieved, guarantee safety and environmental protection, realize green production theory, its indices all can meet the melt pressure sensitive gluing agent properties requirement with rosin resin as viscosifier, it is ensured that makes finished product pressure sensitive adhesive in bonding, produce physical crosslinking in solidification process, while the cohesive strength that improves glue and have water white transparency, the feature such as nonpoisonous and tasteless, ageing-resistant.
3, mineral oil is added, solve the problem affecting product mechanical performance because softening agent effect causes viscosifier viscosity to deteriorate that traditional handicraft produces, UV absorbent is a kind of base oil simultaneously, mineral oil dissolves each other with semisolid rosin ester, make its formation liquid, while ensure that its good mobility and viscosity, the consumption of SBS can be reduced during with this light color liquid production of resins this pressure-sensitive adhesive agent, cost can be reduced.
