Abstract

The invention discloses a cleaning, derusting and phosphating agent. The cleaning, derusting and phosphating agent comprises the following formula components of raw materials in parts: 10-30 parts of phosphoric acid, 5-10 parts of metaphosphoric acid, 8-10 parts of hypochlorous acid, 5-10 parts of banana oil, 5-8 parts of dimethylbenzene, 5-12 parts of silicone oil, 5-10 parts of methyl ethyl ketone, 5-8 parts of isopropanol, 5-8 parts of diethyl ether, 3-5 parts of urea, 5-6 parts of m-dihydroxybenzene, 3-5 parts of p-hydroxyanisole, 5-8 parts of phenol, 5-8 parts of sodium polyacrylate, 2-3 parts of cocamidopropyl betaine, and 50-60 parts of de-ionized water. The cleaning, derusting and phosphating agent can be used at the normal temperature, has the advantages of quick phosphating speed, good phosphating effect, no corrosiveness, little waste residue discharge, combined completion of cleaning, derusting and phosphating at one step, easy production and low production cost, and can be applied to the degreasing, derusting and phosphating treatment of steel and cast iron products.

Description

technical field [0001] The invention relates to the technical field of phosphating agents, in particular to a phosphating agent capable of cleaning and derusting which is used in the steel surface coating process. Background technique [0002] In the prior art, phosphating the surface of steel objects is an important process in the steel coating process. At present, various phosphating agents (also known as phosphating solutions) used in surface treatment of steel objects can basically meet the needs of painting production. However, there are still problems such as unsatisfactory phosphating effect to varying degrees, many restrictions on the use of phosphating agents, high temperature requirements for the use environment, and high energy consumption; Pollution problems caused by secondary discharge of waste residues. The above problems directly affect the quality, output or cost of coating production. Contents of the invention [0003] The purpose of the present invent...
