Embodiment Construction
[0025] Mix nano-silica, anhydrous toluene and dimethyldichlorosilane at a mass ratio of 1:15:0.4, and after ultrasonication for 10 to 15 minutes, stir at a stirring speed of 200 to 400 r / min for 20 to 30 minutes to obtain the dispersion Liquid, according to the mass ratio of 1:8, add n-hexane to the dispersion liquid, under nitrogen atmosphere, stir and react at a temperature of 50-60 °C for 2-4 hours, and then obtain a suspension, centrifuge to obtain a precipitate, respectively use Wash the precipitate with water, toluene and methanol for 3 to 5 times, and dry it in an oven at a temperature of 50 to 60°C to constant weight to obtain modified nano-silica; mix 1-butyl-3 -Methylimidazolium tetrafluoroborate and 1-butyl-3-methylimidazolium hexafluorophosphate are mixed evenly to obtain a stabilizer, and alkyl glycoside and fatty alcohol polyvinyl ether sodium sulfate are mixed in a mass ratio of 2:3 Mix evenly to get the mixed surfactant; in parts by weight, weigh 0.01-0.1 parts...

The invention relates to a preparation method of safe and efficient liquid bleach, and belongs to the technical field of daily chemical supplies. Alkyl glycoside and sodium fatty alcohol ether sulfateare adopted as a surface active agent, alkyl glycoside has a glucoside bond, the stabilizing effect is achieved for the liquid bleach hydrogen peroxide system, peroxides in the liquid bleach are notoxidized by the solution, no free-state oxygen is freed, the effective oxygen has no obvious fluctuation, the sodium fatty alcohol ether sulfate can keep the stability of effective oxygen in the liquid bleach, by mixing alkyl glycoside and sodium fatty alcohol ether sulfate, the effects of wetting, permeating, emulsifying, dispersing, removing stains and the like are achieved, the effects can be used for ensuring that hydrogen peroxide, namely the oxygen containing the bleaching agent evenly and rapidly permeates the fabric fiber, chemical structures of colorful stains stained on fiber is completely broken, meanwhile, other residual stains are removed, and the original whiteness of the fabric is recovered.
Description
technical field [0001] The invention relates to a method for preparing a safe and efficient color bleaching solution, which belongs to the technical field of daily chemical products. Background technique [0002] In daily life, people's clothes are often stained with various stains (such as tea stains, fruit and vegetable stains, etc.) due to various reasons. However, in order to effectively remove various stains on clothes, people usually use Detergents with a bleaching effect (such as chemical bleach, etc.) to clean residual stains on clothes. [0003] In general, chemical bleaching agents are divided into two categories, namely, chlorine-containing color bleaching liquid and oxygen-containing color bleaching liquid. The bleaching effect of chlorine-containing color bleaching liquid is good, but it is easy to damage or fade silk, wool products and some colored fabrics, and at the same time, it has a greater damage to the skin of the hands, so its application range is limi...
