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 now are phosphorous grease-removing agent, and it can cause certain detrimentally affect to environment, and along with the day by day reinforcement of country to environment protection, using agent of non-phosphate degreasing is the first-selection of present most of enterprise.And the agent of non-phosphate degreasing that exists on the market mainly forms with highly basic and the assembly of exhibiting high surface promoting agent, also has the excessive problem of foam that thoroughly do not reach of cleaning.

Summary of the invention

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

Agent of non-phosphate degreasing provided by the invention, form by 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 yellow soda ash, the sodium hydrogencarbonate; Water glass is the 1-2 kind of water glass, Starso; Basic salt is Pottasium Hydroxide or sodium hydroxide, and sequestrant is Sunmorl N 60S, EDTA Disodium or tetrasodium ethylenediamine tetraacetate, and tensio-active agent is low bubble property 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, add component of inorganic salts according to part by weight and stir, add sequestrant and surface active agent composition again, integral body stirs and gets final product.

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