Abstract

The invention discloses a normal temperature three-in-one phosphorizing agent capable of cleaning and derusting synchronously and preparing process thereof, wherein the bonderite comprises phosphorus acid, methyl ketone, ethanol, hydroquinone, non-ionic active agent and water as raw material, which is prepared through the steps of agitating, emulsifying and restirring.

Description

technical field [0001] The invention relates to a phosphating agent used in the steel surface coating process and a preparation method thereof. Background technique [0002] Phosphating treatment on 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 coating 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 object of the present invention is to provide a three-in-one cleaning, derusting and phosphating agent at...
