Abstract

The invention discloses a glutinous rice wet glue with high bonding strength, wherein the glutinous rice wet glue comprises the raw materials in parts by weight: 115-125 parts of a main material, 2-8parts of urea, 1-2 parts of hydrogen peroxide, 1-2 parts of sodium benzoate, 1-2 parts of a bactericide, 2-5 parts of an epoxidized soybean oil compound, 2-4 parts of sodium polyacrylate, 10-16 partsof alum, and 200-300 parts of deionized water. The main material comprises the raw materials in parts by weight: 60-80 parts of glutinous rice flour, 15-35 parts of japonica rice flour, 15-25 parts ofbaked dextrin, and 4-10 parts of carboxymethylated starch. The glutinous rice wet glue with high bonding strength is relatively low in cost, rich in raw material sources, high in bonding strength, safe, environmentally friendly, degradable and not easy to harden after being stored for a long time, and has the viscosity and stability improved.

Description

technical field [0001] The invention relates to the technical field of glutinous rice wet glue, in particular to a glutinous rice wet glue with high bonding strength. Background technique [0002] Glutinous rice wet glue, also known as Japanese wet glue, is a special adhesive for wallpaper. Corn starch, esterified starch, oxidized starch, glutinous rice starch, corn starch, carboxymethylated starch, etc. are cross-linked and complexed by additives, gelatinized at 85°C, and modified by adding various additives after cooling down. It is made by adding white latex to increase viscosity. [0003] At present, the sticky rice wet glue used in the wallpaper industry generally has low viscosity, poor anti-aging, storage thickening and hardening, and causes the problem of viscosity drop, which needs to be solved urgently. Contents of the invention [0004] Based on the technical problems in the background technology, the present invention proposes a glutinous rice wet glue with h...
