▎ 摘　　要

NOVELTY - Adhesive bottom paint composition comprises A component comprising polyol with hydroxy content more than 3%, containing polyolefin structure and modified graphite oxide and B component comprising soybean oil polyol modified product, where the hydroxy in the polyol compound is obtained by ester hydrolysis, the soybean oil polyol modified product is the soybean oil polyol with isocyanate reaction, the soybean oil polyol modified product is obtained by reacting soybean oil polyol with isocyanate, then reacting with the hydrogenated bisphenol A of the preset weight ratio to obtain the added soybean oil polyol of hydrogenated bisphenol A, continuously reacting isocyanate and hydrogenated bisphenol A-added soybean oil polyol. USE - The composition is useful for bonding thermoplastic elastomer and low surface energy substrate (claimed). ADVANTAGE - The method improves the adhesion between the thermoplastic elastomers and glass and has shading effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing adhesive bottom paint composition comprising (i) preparing A component by mixing polyol containing polyolefin structure and modified graphite oxide, where the weight of the modified graphite oxide is 0.5-5 wt.%, (ii) preparing B component by reacting the soybean oil polyol with isocyanate, and then reacting with hydrogenated bisphenol A to obtain hydrogenated bisphenol A addition of soybean oil polyol, then continuously reacting the isocyanate with hydrogenated bisphenol A addition of soybean oil polyol, monitoring the viscosity of the reactant, ensuring the viscosity does not continue to increase, obtaining the modified product of isocyanate-terminated soybean oil polyol, (iii) preparing primer by taking solid A component solution and B component solution, mixing the A component and B component in a mixing ratio of 10-1:1 and the preset solid content range of 5-30%.
