PLASTISOL BASED ON POLYVINYLCHLORIDE OR VINYL CHLORIDE/VINYL ACETATE COPOLYMER Russian patent published in 2003 - IPC

FIELD: adhesives. SUBSTANCE: invention provides adhesive plastisols based on polyvinylchloride or vinyl chloride copolymers appropriate as glues for motor car oil, fuel, and air filters, and for sealing and protecting metallic surfaces. In particular, title plastisol also contains plasticizer: phthalic acid ester or its mixture with dioctyl adipate, dioctyl sebacate, or with plasticizer called EDOS; thermal stabilizer; calcium oxide; anilino-phenol-formaldehyde resin (SF 342A2); and polyethylene-polyamine-based adhesion promoter, in particular reaction product of polyethylene-polyamine and 4,4'-isopropylidenediphenol epoxide resin obtained at their equivalent ratio (7.4-12.4): 1 having amine number 600-806 mg KOH/g and viscosity 103-300 Pa. s; said thermal stabilizer being calcium stearate/zinc stearate mixture or dicyanodiamide/zinc oxide mixture. Plastisol of invention is characterized by shear adhesive strength 7.9-9.0 MPa and thermal stability at 200 C up to 40-50 min. EFFECT: improved adhesive and thermal characteristics. 1 tbl, 3 ex
