Problems solved by technology

In recent years, water-based polyurethane adhesives and water-based neoprene adhesives have also appeared on the domestic market, but due to different shortcomings, product promotion has been greatly affected
One-component water-based polyurethane adhesives have poor initial viscosity and need to be activated by heating before use; one-component water-based neoprene also has poor initial viscosity, serious atomization during spraying, and high cost and unstable supply
After the two-component water-based spray glue is connected and cured, the glue layer is easy to harden, especially at the edge of the joint. In addition, for oily leather and imitation leather materials, the traditional spray glue has poor oil resistance, especially the initial adhesion. And the final adhesion is not ideal, which directly affects the firmness and stability of the arc bonding between leather and sponge

Abstract

The invention discloses modified waterborne SBS (styrene-butadiene-styrene) emulsion glue spray. The modified waterborne SBS emulsion glue spray is prepared from components in percentage by mass as follows: 40wt%-70wt% of acrylate modified SBS latex (with solid content being 50wt%), 10wt%-30wt% of styrene-acrylic emulsion (with solid content being 45wt%-60wt%), 5wt%-10wt% of tertiary carbon emulsion, 5wt%-20wt% of tackifying emulsion, 0.2wt%-3wt% of an aqueous coagulant solution, 0.1wt%-0.5wt% of an anti-aging agent, 0.1wt%-1wt% of a stabilizer and 0.2wt%-1wt% of a thickening agent. The modified waterborne SBS emulsion glue spray has the advantages of being excellent in performance, moderate in cost, environmentally friendly, non-toxic and applicable to the glue spray industry, the strength construction is fast, and technological operation is easy.

Description

technical field [0001] The invention relates to the field of water-based spray glue, in particular to a modified water-based SBS emulsion spray glue and a preparation method thereof. Background technique [0002] Spray glue is an adhesive that closely connects the same or different material interfaces and plays the role of transfer application. It is widely used in furniture, leather and decoration industries. At present, the spray glue on the market is mainly solvent-based spray glue. Solvent-based spray glue is mainly composed of polymers and solvents. The polymers are generally chloroprene rubber (CR) and styrene copolymer (SBS), and the solvents are toluene, chlorinated olefins, methyl ethyl ketone, ethyl acetate, etc. During use, a large amount of organic solvents will volatilize and cause great harm to human health. In addition, because these solvents have extremely low volatilization points and are prone to combustion and explosion, there are major safety hazards su...
