Embodiment 1

[0019] The weight ratio of each component of antibacterial and mildew-proof starch glue for wallpaper is: 100 parts of deionized water, 7 parts of indica rice flour, 5 parts of glutinous rice flour, 5 parts of tapioca starch, 0.1 part of borax, 0.03 part of natamycin, deacetic acid 0.1 part of sodium, 0.1 part of 2-n-octyl-4-isothiazolin-3-one.

[0020] Preparation method: Soak indica rice and glutinous rice for 12 hours, grind into rice slurry, start the mixer of the reactor, add rice slurry, deionized water, tapioca starch and borax into the reactor in sequence to form starch slurry; Steam is passed into the jacket to raise the temperature of the system to 85°C. When the temperature reaches the specified temperature, the reaction is maintained at this temperature for 30 minutes, so that the starch slurry is fully gelatinized and complexed to form a viscous latex liquid; the cooling water is passed through Put it into the reaction kettle jacket, cool the starch glue to 40°C, ...

Abstract

An antibiotic and mildew-resistant starch adhesive for wallpaper comprises 100 parts of deionized water, 4-15 parts of rice, 2-10 parts of potato starch, 0.05-1 part of a complexing agent, 0.01-0.5 parts of an in-can preservative, and 0.02-0.8 parts of a dry film bacterium killing mildew inhibitor. The adhesive has a good bonding performance, and especially the adhesive contains 0.01-0.5 parts of an antiseptic and 0.08-0.8 parts of the dry film mildew inhibitor. The adhesive has a good bonding performance, especially the excellent antibacterial property of the adhesive can guarantee the quality of the adhesive in a storage retention range and the long-acting bonding of an adhesive film to the wall paper and avoids moldy degumming of the adhesive.

Description

technical field [0001] The invention belongs to the field of starch glue, in particular to an antibacterial and mildew-proof starch glue for wallpaper and a preparation method thereof. Background technique [0002] In the wall decoration, it is favored by the price because of its various patterns, beautiful appearance, and convenient decoration, and has become the mainstream of wall decoration in homes, offices and businesses. Wallpaper glue is an adhesive specially used to paste wallpaper. At present, there are many kinds of wallpaper adhesives on the market, which can be generally divided into two categories: synthetic polymer adhesives and biological starch-based nodules. Bio-starch adhesives have gradually replaced synthetic polymer adhesives and become the mainstream of wallpaper adhesives due to their advantages of low-carbon environmental protection, formaldehyde-free, and high cost performance. However, the bio-starch adhesive with starch as the main component is pr...
