A glutinous rice environment-friendly starch type adhesive and a preparing process thereof

Abstract

A glutinous rice environment-friendly starch type adhesive and a preparing process thereof are disclosed. The adhesive comprises following raw materials by weight: 55-110 parts of glutinous rice flour, 40-60 parts of chloroprene latex, 30-55 parts of synthetic resin, 1-10 parts of an additive and 1-8 parts of an auxiliary agent. The adhesive is prepared by cleaning and soaking the glutinous rice flour, adding deionized water into the glutinous rice flour, cooking the mixture until slurry is formed, filtering the cooked glutinous rice flour to obtain a glutinous rice adhesive precursor, mixing other raw materials, adding deionized water into the raw material mixture, fully stirring the raw material mixture, then adding the precursor into the raw material mixture, and heating and stirring the obtained mixture. The adhesive is an efficient water-soluble adhesive, and has advantages of no toxicity, capability of being non-combustible and environment-friendly, rapid drying, high initial adhesive force, good heat resistance, good ageing resistance, and the like. The adhesive is suitable for manufacturing furniture, office chairs, mattresses, sofas, pillows and other soft furniture, and for manufacturing automotive trim, bags, suitcases, and leather products, and can be used for adhering various polar water-absorbing materials. According to the adhesive and the process, the adopted raw materials are simple, the preparing process is easy to operate and control, the production cost is low and the adhesive and the process are suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly starch-based adhesive for glutinous rice and a manufacturing process 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. Safe and environmentally friendly wallpaper materials are recognized by everyone, but compared with wallpaper, the safety of its auxiliary materials cannot be ignored. On the market, the glue used for pasting wallpaper basically includes glue powder, mucilage, wet glue, etc. Generally, the raw material of the glue is formaldehyde, which is a chemical reagent harmful to the human body. The glue powder will be used with the glue, or Used alone, but its environmental performance is relatively poor. The most comm...

Problems solved by technology

Safe and environmentally friendly wallpaper materials are recognized by everyone, but compared with wallpaper, the safety of its auxiliary materials is also a problem that cannot be ignored

On the market, the glue used for pasting wallpaper basically includes rubber powder, glue, wet glue, etc. Generally, the raw material of glue is formaldehyde, which is a chemical reagent harmful to the human body. The glue powder will be used with the glue, or Used alone, but its environmental performance is relatively poor

The most commonly used ones are liquid starch glue or glutinous rice glue or powder, but the traditional glutinous rice glue has the following defects: poor bonding performance, poor water solubility, usually need to add water three or four times, easy to agglomerate, not conducive to construction, not environmentally friendly
