Detergent for household dishwasher and preparation method thereof

Abstract

The invention belongs to the technical field of detergents, and particularly relates to a detergent for household dish washing machines and a method for preparing the detergent. The detergent for thehousehold dish washing machines comprises preparation raw materials including, by weight, 2-10 parts of sodium metasilicate, 2-20 parts of sodium carbonate, 3-20 parts of sodium bicarbonate, 1.5-4 parts of sodium citrate, 10-16 parts of scale inhibitors, 1-8 parts of nonionic surfactants, 0.1-2 parts of active enzymes, 30-40 parts of fillers, 5-20 parts of sodium percarbonate, 0.2-3 parts of tetraacetylenediamine, 0.5-5 parts of citric acid and 0.1-3 parts of essence. The detergent for the household dish washing machines and the method have the advantages that the detergent can effectively adapt to hard water washing and is high in dirt peeling ability, excellent effects of protecting the dish washing machines and tableware can be realized by the detergent, and generated foam can be reduced to a great extent; the excellent stability of the active enzymes can be kept under alkaline conditions, the water-saving performance can be greatly improved, the production cost can be effectively reduced, and decontamination effects can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of detergents, and in particular relates to a household dishwasher detergent and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, automatic dishwashers have become more and more popular, replacing traditional hand-washing tableware, greatly saving time and increasing the cleanliness of tableware. At present, household dishwashers can be divided into two categories according to different washing forms: nozzle-type dishwashers and impeller-type dishwashers, among which nozzle-type dishwashers are also called shower-type dishwashers. The dishwasher removes the dirt on the tableware mainly through the spraying effect generated by the strong water flow in the three-dimensional space, the thermal energy effect of the heated water and the degreasing and decontaminating effect of the detergent. The cleaning is thorough and can be effectively removed. For...

Problems solved by technology

[0003] At present, most of the detergents for dishwashers contain strong alkaline substances. Although they are beneficial to improve the decontamination ability, these strong alkaline substances have a certain corrosive effect on tableware and dishwashers, especially under heating conditions. Moreover, the household water is hard water, which will also cause serious fouling of the dishwasher and tableware, which will not only cause a certain loss to the machine, increase the energy consumption of washing, but also affect the brightness of the tableware.

For example, the Chinese patent document CN 104893870A discloses a phosphide-free domestic automatic dishwasher detergent and its preparation method. The detergent contains the following preparation raw materials in weight percentages: chelating agent 4-8%, alkali source providing agent 30-45%, non-ionic surfactant 2-5%, suspending and dispersing agent 5-15%, oxidative bleaching agent 10-20%, activator 0.1-5%, filler 10-50%, essence 0.1-0.3% And 0.1-5% of other additives, it has a good decontamination effect and is safe to use, but a large proportion of alkaline substances are added to the detergent, and long-term use will cause certain corrosion to tableware and dishwashers , will also bring fouling

Chinese patent document CN 107523428A discloses a detergent composition and its application. The detergent composition includes dicarboxymethylalanine and its salt, polymer containing acrylic acid monomer and its salt, surfactant, oxidant As well as enzyme preparations, etc., the special detergent for dishwashers prepared by using the composition has good scale resistance and decontamination ability, but the stability of the enzyme preparation in the composition is not good, and it will have a certain effect on the decontamination ability. influences

[0004] Therefore, based on the fact that most of the current dishwasher detergents have strong alkalinity and are likely to cause corrosion or fouling of dishwashers or tableware, it is necessary to provide people with a detergent that has strong decontamination ability and can protect tableware well. Household dishwasher detergent free from corrosion and fouling and stable in properties and preparation method thereof
