[0032] The preparation method of glutinous rice base glue is:

[0033] (1) Wash the glutinous rice, grind and crush it through a 200-mesh sieve, collect the sieved particles, add water to the sieved particles at a mass ratio of 5~8:10~15, and gelatinize at 50~60°C for 1~3 hours to obtain a paste Add α-amylase with 3-5% gelatinization liquid, stir and mix at 50-60°C for 20-30min, then add 1-3% gelatinized calcium acetate, heat up to 85-95°C 30~50min, inactivate the enzyme, cool to room temperature, and obtain the cooled product;

[0034](2) In terms of parts by mass, take 30~50 parts of cooling material, 0.2~0.5 parts of sodium bromide, 0.03~0.06 parts of 2,2,6,6-tetramethylpiperidine oxide, and 10~15 parts of hydrogen peroxide , Stir and mix at 20~25°C for 20~30min to obtain a mixture, take the mixture according to the mass ratio of 10~15:3~5, add 20% sodium hydroxide solution, stir and mix for 1~3h, adjust the pH to 7~ 7.2. To obtain the stirred mixture, take the stirred mi...

Abstract

The invention discloses anti-warping glutinous rice glue and a preparation method thereof, and belongs to the technical field of building materials. Glutinous rice base glue is prepared by taking glutinous rice as a raw material for gelatinization, alpha-amylase is added to cut off starch molecular main chains, and then a part of alcohol hydroxyl groups on the starch molecular chains are oxidizedby substances such as hydrogen peroxide and the like, so that solubility of the glutinous rice glue is enhanced. According to the invention, palm oil and the like are taken as raw materials, vermiculite and diatomaceous earth are added at the same time, moisture of the glutinous rice glue is kept through water absorption, and bonding performance is improved. An amphiphilic moisturizing active agent is prepared by carrying out a reaction on coconut oil acyl chloride with phospholipid, and glacial acetic acid and the like are added for a reaction to form a stable glutinous rice glue system, so that warping possibility of wallpaper is reduced. The glutinous rice based glue is used for improving permeability of the glutinous rice glue, a grease additive is added for preventing dry shrinkage and cracking, and the amphiphilic moisturizing active agent is added to reduce warping of the wallpaper, so that usability of the glutinous rice rubber is improved. According to the invention, the problem that the wallpaper is warped due to the fact that a hardening phenomenon occurs easily after existing glutinous rice glue is used for construction is solved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an anti-warping glutinous rice glue and a preparation method thereof. Background technique [0002] At present, people have higher and higher requirements for decoration materials, and the environmental protection performance of decoration materials has become one of the necessary conditions for many people to consider. As a kind of interior decoration material, wallpaper is widely accepted by the public because of its diverse colors, safety and environmental protection, convenient construction, and being applicable to different occasions. Safe and environmentally friendly wallpaper materials are recognized by everyone, but compared with wallpaper, the safety of its auxiliary materials cannot be ignored. [0003] At present, on the market, the glue used for pasting wallpaper basically includes rubber powder, mucilage, wet glue, etc. Generally, the raw mate...
