Abstract

The invention provides a phosphate-free degreasing agent which is prepared through the components according to the following weight percents: 25 to 45 percent of carbonate, 30 to 50 percent of silicate, 10 to 25 percent of basic salt, 2 to 5 percent of chelating agent, and 5 to 10 percent of surface-active agent. The phosphate-free degreasing agent provided by the invention not only achieve the purpose of phosphate free, but also has the advantages of low using temperature, low foaming, high cleaning capability and the like.

Description

A kind of agent of non-phosphate degreasing

Technical field

The invention belongs to a kind of metallic material surface detergent, be specifically related to a kind of agent of non-phosphate degreasing.

Background technology

A large amount of grease-removing agents of selling on the market are now phosphorous grease-removing agent, and it can cause certain detrimentally affect to environment, along with the day by day reinforcement of country to environment protection, use the first-selection that agent of non-phosphate degreasing is present most of enterprise.And the agent of non-phosphate degreasing existing on market mainly forms with highly basic and the assembly of exhibiting high surface promoting agent, also there is not thorough and the excessive problem of foam of cleaning.

Summary of the invention

The object of this invention is to provide a kind of agent of non-phosphate degreasing, easy control techniques requirement during use, cleansing power is strong, generation foam is low.

Agent of non-phosphate degreasing provided by the invention, is comprised of following substances in percentage by weight:

Carbonate 25 ~ 45%,

Silicate 30 ~ 50%,

Basic salt 10% ~ 25%,

Sequestrant 2 ~ 5%,

Tensio-active agent 5 ~ 10;

Wherein, carbonate is the 1-2 kind in sodium carbonate, sodium bicarbonate, water glass is the 1-2 kind of water glass, Starso, basic salt is potassium hydroxide or sodium hydroxide, sequestrant is Sunmorl N 60S, disodium ethylene diamine tetraacetate or tetrasodium ethylenediamine tetraacetate, and tensio-active agent is low bubble ethanol class surfactant B O-902 and alkyl polyoxyethylene polyethenoxy ether LG-299.

The preparation method of above-mentioned grease-removing agent is: in existing volume container, according to part by weight, add component of inorganic salts to stir, then add sequestrant and surface active agent composition, integral body stirs.

Advantage of the present invention is: easy control techniques requirement during use, cleansing power is strong, produces foam low.
