Abstract

The invention discloses high-adhesion sealant, comprising, by weight, 90-100 parts of chlorinated PVC resin, 40-60 parts of PVC (polyvinyl chloride) resin, 30-50 parts of alkyd resin, 50-60 parts of ultrahigh molecular weight polyvinyl chloride with molecular weight of 1.60 million, 15-25 parts of dibutyl phthalate, 20-30 parts of dioctyl phthalate, 10-15 parts of dioctanoate adipate, 560-672 parts of gasoline, 400-480 parts of ethyl acetate, 240-288 parts of acetone, 23-26 parts of rutile titanium dioxide, 120-140 parts of light calcium carbonate, 250-270 parts of talcum powder, 20-23 parts of sericite, 10-13 parts of vulcanized paste, 30-50 parts of diatomite, 0.4-0.6 part of an ultraviolet stabilizer, and 0.05-0.1 part of an antioxidant. The high-adhesion sealant has the advantages that the sealant with excellent comprehensive properties is acquired by component optimization, usage of harmful matters is reduced, environmental pollution is reduced, and the preparation process is updated according to the optimized composition.

Description

technical field [0001] The invention belongs to the technical field of sealants, and in particular relates to a high-adhesion sealant and a preparation method thereof. Background technique [0002] A sealant is a flowable or extruded unshaped material to fill a closed joint that can rely on embedded drying, temperature changes, solvent evaporation, chemical cross-linking of the material to stabilize the material, and the gradual incorporation of a solid adhesive, viscoelastic behavior or elasticity Sealing material molding. In order to ensure the sealing function, the sealant should have the following basic characteristics: ① good embedding, storage stability, non-toxic or low toxicity; ② low penetration with other media; ③ seams that can resist telescopic movement, displacement and deformation; ④ In the joints subjected to cyclic deformation, it can ensure the complete recovery of its performance and shape; ⑤ have enough strength to withstand pressure; ⑥ not embrittlement ...
