Problems solved by technology

[0002] At present, most of the environmentally friendly adhesives for wallpaper are liquid starch glue or glutinous rice glue or powder, but the traditional glutinous rice glue has the following defects: 1. It is generally translucent colloid, with poor bonding performance and poor appearance; 2. Water-soluble Poor performance, usually needs to be watered three or four times, easy to agglomerate, not conducive to construction; 3. Due to the molecular structure of most starches, it does not have antifreeze ability and cannot be stored in a low temperature environment; 4. Too many additives, Not conducive to environmental protection

Embodiment 1

[0025] Soak the glutinous rice glue raw material from which impurities have been removed for 3 hours; the glutinous rice glue raw material is 10-30% glutinous rice and 70-90% japonica rice.

[0026] The soaked glutinous rice is screened and filtered with a 100-mesh sieve after defibrination;

[0027] The filtered glutinous rice glue is gelatinized at a high temperature of 90 degrees.

Embodiment 2

[0029] Soak the glutinous rice glue raw material from which impurities have been removed for 5 hours; the glutinous rice glue raw material is 40-60% glutinous rice and 40-60% japonica rice.

[0030] The soaked glutinous rice is screened and filtered with 105 mesh sieves after defibrination;

[0031] The filtered glutinous rice glue is subjected to high temperature gelatinization at 100 degrees.

Embodiment 3

[0033] Soak the glutinous rice glue raw material from which impurities have been removed for 10 hours; the glutinous rice glue raw material is 50--80% glutinous rice and 20-50% japonica rice.

[0034] The soaked glutinous rice glue is screened and filtered with 110 mesh sieves after defibrination;

[0035] The filtered glutinous rice glue is gelatinized at a high temperature of 115 degrees.

Abstract

A preparation method for glutinous rice glue includes following steps of: soaking an impurity-removed glutinous rice glue raw material for 1-12 hours, carrying out a pulp grinding process to the soaked glutinous rice glue, filtering the glutinous rice glue through a 100 meshes screen mesh and carrying out a high-temperature gelatinization process to the filtered glutinous rice glue at 120 DEG C. The glutinous rice glue is strong in binding force, is good in constructability, is mouldproof and anti-bacterial, and is suitable for a bond between various wall papers and a substrate. A performance of the glutinous rice glue can accord with a standard requirement in JC / T548-1994 "wall paper adhesive". Both a starch adhesiveness and a peel strength preserving rate of the glutinous rice glue are greater than 85% through a three-time freeze-thaw freezing-cycle test at -20 DEG C.
