Problems solved by technology

The surface of attapulgite is hydrophilic, so it is only suitable for use in polar systems, but it is difficult to disperse when added to organic systems such as plastics, rubber, chemical fibers, and solvent-based coatings, and cannot reflect the special functions of attapulgite.
The bleaching agents on the market now contain ingredients that pollute the environment or are harmful to laundry, so a better bleaching agent is needed to meet people's environmental protection requirements

Abstract

The invention provides a bleaching agent containing attapulgite and a preparation method thereof. The bleaching agent takes attapulgite as a main component and further contains sodium hydroxide, fatty alcohol-polyoxyethylene ether, acrylic acid, essence, anion stabilizer, auxiliary bleaching agent, foaming agent and water. The bleaching agent provided by the invention has excellent effect, high stability and wide application field; the adopted attapulgite component has the characteristics of environmental protection and no pollution; the decontamination capacity is high; the bleaching agent is harmless to washed articles; the bleaching agent is low in cost, simple in manufacturing process, free from exhaust gas pollutant generated in the production process and capable of meeting the environment-friendly green development requirement in the modern society.

Description

technical field [0001] The invention belongs to the technical field of washing products, and in particular relates to a bleaching agent containing attapulgite and a preparation method thereof. Background technique [0002] Bleaching is the process of decomposing and decolorizing colored substances by chemical action to obtain the necessary whiteness. As we all know, bleaching has a wide range of applications in many fields such as textiles, papermaking, washing, food, and medical treatment. Currently, bleaching products widely used in the market are generally divided into two categories: chlorine bleach and oxygen bleach. Chlorine bleaches contain sodium hypochlorite, calcium hypochlorite, chlorine dioxide, etc. while oxygen bleaches contain hydrogen peroxide or compounds that release peroxides, such as sodium perborate or sodium percarbonate. With the advancement of material science and the improvement of preparation technology, attapulgite materials have come into people...
