preparation example Construction

[0032] In one of the specific embodiments, the preparation method of the component A and / or the component B comprises the following steps:

[0033] adding water to the binder to make a binder solution;

[0034] Soda ash or sodium sulfate is granulated with the binder solution and dried.

[0035] More specifically, the mass concentration of the binder in the binder solution is 0.5-20%.

[0036] More specifically, the drying temperature is 80-95° C., and the drying time is 1-8 hours.

[0037] More specifically, the water is first heated to 50-80° C., then the binder is added and stirred to dissolve.

[0038] In one specific embodiment, the copolymer dispersant is one or more of vinyl monomer copolymers containing carboxylic acid groups or containing sulfonic acid groups. The use of this type of copolymer dispersant is beneficial to the uniform dispersion of soda ash and sodium sulfate in the system for adhesive bonding, good fluidity and stable detergency.

Abstract

The invention relates to washing powder, which is prepared from the following raw materials in percentage by mass: 0.1%-40% of a component A, 0.1%-30% of a component B, 0.1%-20% of a surfactant, 0.1%-10% of a copolymer dispersing agent and 0.1%-90% of a functional aid, wherein the component A is particles prepared by mixing and granulating sodium carbonate and an adhesive, the mesh number of the component A is 10-200, the component B is particles prepared by mixing and granulating sodium sulfate and an adhesive, the mesh number of the component B is 10-150, and the adhesives in the component Aand the component B are respectively and independently selected from one or a composition of two of polyvinylpyrrolidone and polyethylene glycol in a specific molecular weight range. The washing powder is uniform in particle, good in flowability, free of dust pollution, good in solubility in the using process, good in decontamination effect and suitable for household dish washing machines.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a detergent powder. Background technique [0002] With the innovation and progress of science and technology, household dishwashers are becoming more and more popular and become the main household appliances in people's daily life. Automatic dishwashers have the advantages of energy saving, convenience, and water saving, and have multiple functions such as cleaning, disinfection, drying, and storage, so they can fully meet the needs of people who want to be freed from simple and repetitive housework. The dishwasher cleans and removes the dirt on the tableware mainly by virtue of the spray effect generated by the strong water flow in the three-dimensional space, the heat energy effect of the heated water, and the degreasing and decontamination effect of the cleaning agent. These three effects are coordinated with each other. The degreasing and stain-removing effec...
