Abstract

The invention relates to an adhesive for wallpaper industry and particularly relates to sticky rice wet glue added with an emulsion stabilizer and a preparation method thereof. According to the invention, the emulsion stabilizer is added in a production process of the sticky rice glue to produce a sticky rice wet glue product. The sticky rice wet glue product has strong binding power and can be mixed with water 100%, the wallpaper adhesion area is increased, the decoration cost of users is reduced, the preparation process is simple, the production cost is low, and the product is stable to store and is convenient to use.

Description

technical field [0001] The invention relates to an adhesive used in the wallpaper industry, in particular to a glutinous rice wet glue added with an emulsification stabilizer and a preparation method thereof. Background technique [0002] Glutinous rice wet glue, also known as Japanese wet glue, is a special adhesive for wallpaper. Use modified waxy corn starch, esterified starch, oxidized starch, glutinous rice starch, corn starch, wheat starch to pass through additive crosslinking and complexation reaction, gelatinize at 85°C, add various additives (preservation, Plastic, etc.) modification, and then add white latex to increase viscosity. Glutinous rice wet glue used in the existing wallpaper industry generally has low viscosity, poor anti-aging, thickening and hardening during storage, poor appearance, poor frost resistance, resulting in decreased viscosity, high cost and glue adjustment during construction. effort etc. Contents of the invention [0003] Aiming at th...
