(2) washing, dried waste PET fragment are joined in reactor in proportion, then add zinc acetate; Slowly be warming up to zinc acetate under nitrogen protection when dissolving completely, warming while stirring to 250-270 DEG C, insulation reaction 3-4h; Be cooled to 200-210 DEG C, then add thiorubber, chloroprene rubber, alkyl phenolic resin, styrene resin, stirring reaction 10-20min; Add the composite powder of modification and all the other raw materials again, after stirring 1-2h, discharging cooling stripping and slicing.
Described a kind of Anti-corrosion hot melt adhesive, is characterized in that: preparation method comprises the following steps:
(1) kneader is preheated to wall temperature 190-200 DEG C;
(2) then add EVA, c5 petroleum resin, carboxy nitrile rubber by weight, mediate 10-20min;
(3) add surplus stock by weight after, at 180-190 DEG C, mediate 30-40min, take out and cool and get final product.
Beneficial effect of the present invention:
(1) raw materials of the present invention contains the raw materials such as c5 petroleum resin, carboxy nitrile rubber, well composite with all the other raw materials, increase the cohesive strength of raw material, then increase erosion resistance of the present invention by adding various filler, have a wide range of applications in packaging field.
(2) modified tacky resin batching rationally, the composite powder of modification wherein contains carbide slag, turn waste into wealth, can carbide slag sterilization be given by uv irradiation again, the hole of carbide slag, gac can be increased simultaneously, strengthen the avidity with resin, ageing-resistant, resistance to air loss is good, not only significantly improves the properties of hot melt adhesive with the composite powder of modification as the new raw material of hot melt adhesive, and has made new contribution for environmental protection.
(3) waste PET fragment by degraded after, then with all the other tackifying resins and the good melting of the composite powder of modification, obtained tackifying resin viscosity is high, and hardness strength performance satisfies the demands; Composite powder can be better dispersed in PET and remaining resin by modified, can increase the tensile strength of sizing material, hardness, nontoxic pollution-free; The present invention successfully by pet waste for the preparation of in hot melt adhesive, obtained hot melt adhesive can meet the sizing agent demand in each field, environmental protection, economy, useful environment.
