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
[0003] At present, on the market, the glue used for pasting wallpaper basically includes rubber powder, mucilage, wet glue, etc. Generally, the raw material of the mucilage is formaldehyde, which is a chemical reagent harmful to the human body, and the glue powder will be used together with the mucilage , or used alone, but its environmental performance is relatively poor

Embodiment 1-2

[0025] A kind of antibacterial glutinous rice glue, its raw material formula is shown in Table 1, and the preparation process of this antibacterial glutinous rice glue is:

[0026] The first step is to wash the glutinous rice and soak it in deionized water for 12 hours; cook the soaked glutinous rice at 90°C for 2 minutes;

[0027] In the second step, grind the cooked glutinous rice, filter it with a 150-mesh filter, add sodium hydroxide to adjust the pH value to 9, react at 60°C for 5h, add sodium tripolyphosphate, react at 60°C for 1h, and then react at 90°C Carry out gelatinization, gelatinize into colloidal glutinous rice starch, measure the content of glutinous rice starch after gelatinization to meet the requirements of product production;

[0028] The third step is to add lignin, diatomaceous earth, sodium benzoate, tannic acid, salicylic acid, iodopropynyl butyl carbamate, propylene glycol, polyoxypropylene successively to the gelatinized glutinous rice starch Ethylen...

Embodiment 3-4

[0030] A kind of antibacterial glutinous rice glue, its raw material formula is shown in Table 1, and the preparation process of this antibacterial glutinous rice glue is:

[0031] The first step is to wash the glutinous rice and soak it in deionized water for 12 hours; cook the soaked glutinous rice at 100°C for 2 minutes;

[0032] The second step is to grind the cooked glutinous rice, filter it with a 150-mesh filter, add sodium hydroxide to adjust the pH value to 10, react at 70°C for 6h, add sodium tripolyphosphate, react at 40°C for 2h, and react at 95°C Carry out gelatinization, gelatinize into colloidal glutinous rice starch, measure the content of glutinous rice starch after gelatinization to meet the requirements of product production;

[0033] The third step is to add lignin, diatomaceous earth, sodium benzoate, tannic acid, salicylic acid, iodopropynyl butyl carbamate, propylene glycol, polyoxypropylene successively to the gelatinized glutinous rice starch Ethylene...

Abstract

The invention relates to glue for wallpaper and in particular relates to antibacterial glutinous rice glue and a preparation method thereof. The antibacterial glutinous rice glue is prepared from the following raw materials in parts by weight: 60 to 80 parts of glutinous rice starch, 1 to 2 parts of lignin, 3 to 5 parts of diatomite, 2 to 3 parts of sodium benzoate, 0.5 to 1 part of tannic acid, 2 to 3 parts of salicylic acid, 1 to 2 parts of sodium triphosphate, 0.5 to 1 part of iodopropynyl butylcarbamate, 1 to 2 parts of propylene glycol, 0.03 to 0.05 part of polyoxypropylene oxyethylene glycol ether, 1 to 2 parts of PEG-60 (Polyethylene Glycol-60) hydrogenated castor oil, 3 to 4 parts of white latex and 30 to 40 parts of de-ionized water. According to the antibacterial glutinous rice glue, the raw material lignin has a sterilization effect and the tannic acid has an antibacterial effect; meanwhile, the sodium benzoate has a mildew-proof effect and athe antibacterial glutinous rice glue has the effect of inhibiting mold.

Description

technical field [0001] The invention relates to a glue for wallpaper, in particular to an antibacterial glutinous rice glue and a preparation method thereof. Background technique [0002] 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 material of the mucilage is formaldehyde, which is a chemical reagent harmful to the human body, and the glue powder will be used together with the mucilage , or used alone, but its environmental performance is relatively poor. At present, in China, glutino...
