Problems solved by technology

Its disadvantage is that the anti-mold powders are all narrow-spectrum anti-mold, which can inhibit the mildew of glass in a narrow range, and can only inhibit the physical and chemical type of mold of glass, but cannot suppress the precipitation of sodium ions, and cannot inhibit the biochemical type of mildew and other types of glass. Pollution-induced mildew, unable to achieve broad-spectrum anti-mold effect on glass
Especially the use of natural plant fiber, under certain conditions, because the plant fiber itself is easy to mold, it will induce mold and glass pollution of the glass, and even make the glass lose its use value

Abstract

A broad spectrum mildew proof powder for soda-lime silicate glass is prepared by mixing styrene and styrene-methyl methacrylate copolymer resin powder, barium sulfate powder, itaconic acid powder, chlorhexidine powder and nanosilicon dioxide in parts by weight. The styrene and styrene-methyl methacrylate copolymer resin powder is taken as a supporting material; barium sulfate and itaconic acid are taken as physical and chemical type mildew inhibition materials; chlorhexidine is taken as a biochemical mildew inhibition material and other pollution induced mildew inhibition materials; nanosilicon dioxide is taken as an anti-blocking and aided flow functional auxiliary. The mildew proof powder can not only suppress monovalent metal ions in the soda-lime silicate glass to prevent denatrium and dealkalization of the glass, but also neutralize basic ions on the surface of the glass, inhibits the generation and the development of physical and chemical type mildews of the glass, also can inhibit and kill bacteria, disturbs the formation of bacterial plaques, inhibits the biochemical mildew generation of other pollution induced midews, and has broad-spectrum mildew inhibition performance on the soda-lime silicate glass.

Description

technical field [0001] The invention relates to a glass anti-mildew powder spread on the surface of flat glass, in particular to a broad-spectrum soda calcium silicate glass anti-mold powder. Background technique [0002] Soda lime silicate glass is the leading product of flat glass and is widely used in construction, automobile, furniture and electronics. During the storage and transportation of soda-lime silicate flat glass, various types of mildew such as physical, chemical, physicochemical, biochemical and other pollution-induced types will occur. After the glass is moldy, spots, potholes, and frost-like defects appear, resulting in rainbows, light distortion, and reduced light transmittance, which seriously affect the use and deep processing of glass, resulting in losses. About 4% of the total production of glass is lost due to mildew. In order to avoid the loss caused by glass mildew, the glass protection method of spreading anti-mold powder on the glass surface is g...
