Abstract

The invention belongs to the field of accessory adhesive in the wallpaper industry, and in particular relates to a glutinous rice wet glue. The glutinous rice wet glue is prepared mainly from the following raw materials, by weight: 75-76 parts of deionized water, 16-17 parts of modified waxy amylopectin, 0.8-1 part of polyethylene glycol, 2 parts of white dextrin, 2 parts of urea, 0.15-0.2 part of non-iron aluminum sulfate, 0.4 part of sodium benzoate, 0.1 part of a defoaming agent, 0.8-1 part of ethylene glycol, 1.5-2 parts of glycerol, 0.2-0.4 part of a bactericide and 3-5 parts of white latex, through gelatinization, crosslinking and complexation reaction. The invention also provides a preparation method of the glutinous rice wet glue. The glutinous rice wet glue provided by the invention has characteristics of strong adhesion, capability to blend with 100% of water, increase on the wallpaper paste area, and reduction of the decoration cost of the users; the preparation method has advantages of simple process and low production cost; and the product has storage stability and good quality.

Description

technical field [0001] The invention belongs to the field of auxiliary material adhesives in the wallpaper industry, and in particular relates to a glutinous rice wet glue and a preparation method thereof. Background technique [0002] For wallpaper paste construction, polyvinyl alcohol and white latex were used in the past. The disadvantages: (1) When the wallpaper is pasted and applied, the leveling and lubricity are low. (2) After the glue is dried, the residual glue at the joints of the wallpaper is not easy to clean up, which affects the aesthetic effect; (3) The cost of polyvinyl alcohol and white latex is high, and the residual monomers in the polymerization process will cause air pollution; (4) The early starch adhesives had poor production facilities and improper raw material compatibility, resulting in a short shelf life of the product, easy yellowing and mildew, and easy to cause secondary pollution to the environment. [0003] Glutinous rice wet glue, also known...
