Abstract

The invention discloses waterproof mildewproof starch glue and a preparation method thereof. the waterproof mildewproof starch glue is mainly prepared from starch, urea formaldehyde resin, borax, propylene glycol alginate, aluminum hydroxyl distearate, sodium hypochloride, diisopropyl phthalate, potassium persulfate, 5-chloro-2-methyl-4-isothiazoline-3-ketone, hydroxyethylmethylcellulose, kaolin, acrylic nuclear glycan, lithium-based bentonite, sodium hydroxide, methyl acrylate, sodium methyl cocoyl taurate and hexamethylene diisocyanate. Through mutual cooperation of the urea formaldehyde resin, ethyl hydrogen-containing silicon oil, aluminum hydroxyl distearate and resorcinol, waterproofness of the starch glue is improved; ethyl lauroyl arginate hydrochloride and 5-chloro-2-methyl-4-isothiazoline-3-ketone have mildewproof and antibacterial effect, thereby being conducive to improving mildewproof and antibacterial performance of the starch glue; ingredients like propylene glycol alginate and acrylic nuclear glycan are conducive to improving stability of the starch glue and prolonging service life of the same.

Description

technical field [0001] The invention relates to the technical field of bonding materials, in particular to a water-resistant and mildew-proof starch glue and a preparation method thereof. Background technique [0002] Agricultural products such as rice, wheat, corn, and potatoes contain a large amount of starch, which can be processed into various forms such as soluble starch, dextrin, and hydroxyethyl ether starch through physical and chemical methods. Therefore, according to different application requirements, with different starches as base materials and corresponding additives, starch glues with different viscosity, solid content, color and mechanical properties can be made. Industrial starch glue usually uses corn as raw material, disperses corn starch in water, then heats or adds a small amount of caustic soda to gelatinize the starch, and then dilutes with water to make ordinary corn starch glue. In the actual preparation of starch glue, 0.2% to 2% of the starch mass...
