Abstract

The invention discloses an EVA hot melt adhesive with high bonding strength. The EVA hot melt adhesive with high bonding strength comprises the following raw materials in parts by weight: 100 parts ofEVA resin, 8-19 parts of SBS thermoplastic elastomer, 4-11 parts of hydroxyl-terminated polyurethane resin, 0.2-1.3 parts of polyacrylamide, 0.15-0.8 part of 2-vinyl-1-benzofuran, 11-15 parts of hydrogenated C5 petroleum resin, 5-13 parts of polyethylene wax, 1-3 parts of paraffin wax, 0.12-0.34 part of an antioxidant, 0.01-0.1 part of benzoyl peroxide, 0.01-0.07 part of europium acrylate and 13-28 parts of filler. The EVA hot melt adhesive with high bonding strength is high in bonding strength, good in high temperature resistance and excellent in aging resistance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an EVA hot-melt adhesive with high bonding strength. Background technique [0002] Hot melt adhesive is a kind of adhesive that uses thermoplastic resin as the base material and adds a small amount of plasticizer, tackifier, filler, antioxidant, etc., and uses temperature changes for bonding. It has many excellent properties, such as 100% solid, short curing time, easy to operate and suitable for continuous industrial production, etc., it has been widely used in home decoration, perfect binding, plastic bonding and other fields. [0003] According to different main resins, hot melt adhesives can be divided into ethylene-vinyl acetate, styrene block elastomers, polyolefins, polyamides, polyesters, etc. Ethylene-vinyl acetate (EVA) hot melt adhesives have the characteristics of excellent weather resistance, non-toxicity, no pollution, and simple preparation methods. , The defec...
