Glutinous rice adhesive subpackagable at high temperature and used for wallpaper, and preparation method thereof

Abstract

The invention relates to the technical field of accessory materials for wallpaper, especially to a glutinous rice adhesive subpackagable at high temperature and used for wallpaper, and a preparation method thereof. The glutinous rice adhesive which can be subpackaged and produced at high temperature and is used for pasting of wallpaper is mainly prepared from the following components by mass: 60 to 80 parts of deionized water, 8 to 15 parts of modified starch A, 4 to 10 parts of modified starch B, 3 to 8 parts of modified starch C, 4 to 10 parts of glutinous rice flour, 0.5 to 1 part of a stabilizing agent, 0.1 to 0.5 part of food-grade calcium propionate, 0.5 to 1.5 parts of sorbitol, 2 to 6 parts of a tackifier and 0.5 to 2 parts of food-grade sodium diacetate. Compared with traditional processes, the glutinous rice adhesive provided by the invention can be directly packaged at high temperature, so the step of cooling is omitted, energy loss is substantially reduced, and the usage efficiency of a reaction vessel is improved.

Description

technical field [0001] The invention relates to the technical field of wallpaper auxiliary materials, in particular to a glutinous rice glue for wallpaper that can be packaged at high temperature and a preparation method thereof. Background technique [0002] At present, wallpaper has become the mainstream trend of wall decoration because of its multiple advantages such as environmentally friendly materials, bright colors, sound insulation and heat preservation, and short construction period. When pasting wallpaper, glutinous rice wet glue is more and more widely used because of its environmental protection, strong adhesion and low cost. Glutinous rice glue is mainly made of various types of starch as the main agent, supplemented by various auxiliary materials, and is an environmentally friendly water-soluble high-viscosity starch glue prepared by heating and reacting in the reactor after appropriate proportioning, and then cooling down and discharging Packing has obtained ...

AI Technical Summary

Problems solved by technology

[0003] At present, the method of preparing glutinous rice glue is to mix the raw materials, then heat in the reactor while stirring or gelatinize with alkali to keep the high temperature for 30 minutes, and then use cooling water circulation to cool down to room temperature, and then use a high-pressure pump to pump into the automatic tank. Machine filling, this process consumes a lot of heat and cold energy, and also consumes a huge amount of electric energy (stirring) and a lot of time, so the production method is not energy-saving, and the cooling needs to be carried out in the reactor

The overall production reaction cycle is long, which consumes huge power and production time, reduces the efficiency of production equipment, and increases the cost of production enterprises
