Abstract

The invention discloses multipurpose spray glue which comprises, by weight parts, 7-9 parts of styrene butadiene rubber (SBR), 33-38 parts of dimethyl carbonate, 14-16 parts of disproportionated rosin, 20-22 parts of ethyl acetate, 2-3 parts of tackifying resin, 1-2 parts of polyvinyl alcohol with a number average molecular weight of 16000-20000, 3-5 parts of hydroxyethyl methylacrylate and 16-18 parts of butane. The invention aims to provide the multipurpose spray glue and a preparation method thereof. The multipurpose spray glue does not corrode light materials such as EPS and Styrofoam, is high in adhesive property, and is low in seepage force when sprayed to the light materials such as EPS and Styrofoam.

Description

Technical field [0001] The invention relates to the field of glue spraying, in particular to a multi-purpose glue spraying and a preparation method thereof. Background technique [0002] Spray glue is used to bond sofa sponge, foam, cloth, leather, paper, wood, plastic, PVC, PE, EVA, metal, rubber, insulation cotton, fireproof board, aluminum-plastic board and other materials. It has been widely used. [0003] When the existing spray glue is applied to the surface adhesion of light materials such as EPS, styrofoam, etc., there are problems of easy corrosion, low adhesion and strong penetration. Summary of the invention [0004] The object of the present invention is to provide a multi-purpose spray glue and a preparation method thereof. The multi-purpose spray glue is not easy to corrode EPS, styrofoam and other lightweight materials, has strong adhesion, and can be sprayed onto EPS, styrofoam and other light materials. Penetration is low when the material is on. [0005] The techni...
