High-performance high-adhesion adhesive for PVC inflatable boat

Abstract

The invention discloses a high-performance high-adhesion adhesive for a PVC inflatable boat. The high-performance high-adhesion adhesive is prepared from a component A, a component B and a component C, wherein the component A consists of toluene, ethanol, petroleum ether, water, HM-828, tackifying resin, a thickening agent, vinyl chloride-vinyl acetate resin, lauric acid, phthalic acid, glycerol,ethylene glycol, trimethylolpropane and ethyl acetate; the component B consists of cottonseed oil, isophorone diisocyanate, unsaturated polyester and ethyl acetate; and the component C consists of starch-vinyl acetate cross-linked graft copolymer, isophorone diisocyanate, trimethylolpropane and ethyl acetate. The adhesive prepared by using a treatment process of the invention has high bonding strength, short curing time, fast film formation speed, high heat sealing strength, extensive purposes, excellent performance and high bonding strength, does not crack when cooked at high-temperature, andis resistant to acid, alkali, oil and salt, free of metal ions and simple in preparation process; since renewable raw materials are utilized, the adhesive is beneficial for environmental protection;and the adhesive is applicable to bonding of PVC inflatable boats.

Description

technical field [0001] The invention belongs to the field of adhesive manufacture, and in particular relates to an adhesive for PVC inflatable boats with high performance and high adhesion. Background technique [0002] Through the adhesion and cohesion of the interface, the natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together are collectively referred to as adhesives, also known as adhesives. Adhesive, customarily referred to as glue. In the manufacture and maintenance of inflatable boats, a large amount of adhesives are needed. The application of epoxy adhesives on ships is that there are many kinds of adhesives based on epoxy resin, and they are widely used. Traditionally produced adhesives for boats are not strong in weather resistance, water resistance, cohesiveness and medium resistance, resulting in serious degumming, which affects the normal work of boats. In order to pursue higher quality products, productio...

AI Technical Summary

Problems solved by technology

Traditionally produced adhesives for boats are not strong in weather resistance, water resistance, cohesiveness and medium resistance, resulting in serious degumming, which affects the normal work of boats. In order to pursue higher quality products, production and development In order to meet the needs of PVC inflatable boats, it is necessary to modify the existing adhesives to meet the needs of repairing and protecting PVC inflatable boats such as wear, erosion, corrosion, leakage, cracks, and scratches.
