Abstract

The invention discloses a preparation method for a composite polymer resin foam adhesive, belonging to the technical field of polymeric materials. The preparation method provided by the invention comprises the following steps: mixing octenyl succinic anhydride modified starch, a natural macromolecular organic matter and water under stirring, carrying out standing and swelling, carrying out heatingunder stirring, carrying out dissolving so as to obtain a mixed solution, then adding linseed oil into the mixed solution, and carrying out stirring at a high speed so as to obtain an emulsion; and subjecting (N-amidino)dodecyl acrylamide, polyethylene glycol phosphate and an additive to a reaction under stirring at a constant temperature so as to prepare a self-prepared surfactant, then mixing the emulsion, the self-prepared surfactant and an anionic polyacrylamide dispersion under stirring, adding a cross-linking agent, carrying out a reaction under stirring at a constant temperature, thensuccessively adding a sodium silicate solution and a polyurethane performed polymer, carrying out mixing under stirring, and carrying out standing and foaming so as to obtain the composite polymer resin foam adhesive. The composite polymer resin foam adhesive prepared by using the preparation method provided by the invention has excellent bonding strength, and does not generate the phenomenon of layering when in storage due to excellent foam stability.

Description

technical field [0001] The invention discloses a preparation method of composite polymer resin foam glue, which belongs to the technical field of polymer materials. Background technique [0002] Styrofoam is a type of rubber. Also known as sponge rubber. Vulcanized rubber with a sponge-like porous structure. There are open pores, closed pores, mixed pores and micropores. It can be made into soft rubber or hard rubber products. Lightweight, soft, elastic, not easy to transfer heat. It has the functions of shockproof, impact mitigation, heat insulation and sound insulation. Made of synthetic rubber, it also has the characteristics of oil resistance, aging resistance and chemical resistance. Widely used in industries such as automobiles, airplanes, chemicals, and daily necessities, as thermal insulation, sound insulation, and shockproof materials, as well as seat cushions, mattresses, medical machinery, sanitary products, sporting goods, etc. It can be made by adding foa...
