Embodiment Construction

[0021] The technical scheme to be solved by the present invention is as follows:

[0022] Raw materials and proportioning are as follows: (the following material components are weight components)

[0023] Sodium bicarbonate 50-60 parts,

[0024] 2-3 parts of hydroxymethylcellulose,

[0025] 11-12 parts of sodium dodecylbenzenesulfonate,

[0026] 6-10 parts of sodium silicate,

[0027] 6-8 parts of fatty acid,

[0028] Sodium perborate 4-6 parts

[0029] Flavor Appropriate amount

[0030] Appropriate amount of fluorescent whitening agent

[0031] The specific production steps are: put 50-60 parts of sodium bicarbonate and 2-3 parts of hydroxymethyl cellulose in a mixer and mix evenly, then add 11-12 parts of sodium dodecylbenzenesulfonate and sodium silicate 6-10 parts, when the reaction is complete, add 6-8 parts of fatty acid, add 4-6 parts of 10% sodium perborate after 24 hours, mix well, and then add appropriate amount of essence and fluorescent whitening agent.

Abstract

The invention relates to the field of laundry supplies, in particular to a non-phosphorous low-foaming washing powder method. The non-phosphorous low-foaming washing powder method includes: filling 50-60 parts of sodium bicarbonate and 2-3 parts of hydroxymethyl cellulose into a mixer to uniformly mix, then adding 1-12 parts of sodium dodecyl benzene sulfonate and 6-10 parts of sodium silicate after mixing, adding 6-8 parts of fatty acid after reaction, adding 4-6 parts of 10% sodium perborate after 24 hours to uniformly mix and adding proper essence and fluorescent brightener. Production equipment for non-phosphorous low-foaming washing powder is simple. The non-phosphorous low-foaming washing powder is low in foaming and applicable to washing machines, utilizes natural plant and animal oil as active matters, is compounded with various high-efficient surfactants and alkalescence builders and is capable of efficiently cleaning, pollution-free and harmless for human bodies. The fluorescent brightener has functions of whitening and brightening, and the essence can make detergents aromatic. The non-phosphorous low-foaming washing powder can be used to wash off gentian violet, ball pen oil, stains of oil, blood, milk, juice and the like which are hard to remove, and is veritable in cleaning.

Description

technical field [0001] The invention relates to the field of laundry products, in particular to a preparation method of a phosphorus-free low-foaming washing powder. Background technique [0002] According to the report of the United Nations Environment Program and other organizations on global water quality monitoring, currently about 30% to 40% of lakes and reservoirs in the world are eutrophic. In my country, many rivers and lakes such as the Yangtze River, Huaihe River, Taihu Lake, and Chaohu Lake have eutrophication problems to varying degrees. According to experts' investigations on water pollution in Chaohu Lake, the phosphorus content in the water easily exceeds the standard by 3.4 times, and the increase in phosphorus content is all due to phosphorus-containing washing powder. 70.8% of the phosphorus in Nanjing Xuanwu Lake comes from domestic sewage; one of the main reasons for the outbreak of blue-green algae in Taihu Lake is also due to the discharge of washing p...
