Metal derusting detergent

Abstract

The invention discloses a metal derusting detergent which is prepared from the following raw materials in parts by weight: 3.4-5.2 parts of dimethyl polysiloxane, 1.5-4.3 parts of sodium tripolycarbonate, 10-14 parts of silane ketone emulsion, 8.4-11.5 parts of silicate, 4.3-7.5 parts of N-phosphonomethyl aminodiacetic acid, 2.3-3.5 parts of deionized water, 4.2-5.5 parts of antistatic agent and 3.4-5.5 parts of polytetrafluoroethylene. The metal derusting detergent provided by the invention has low foam, and can easily remove lubricant grease and other refractory stains in the metal working process; after being cleaned and exposed to air, the metal material can keep rustless for many days; and the metal derusting detergent is effective for iron materials, copper materials, aluminum materials and composite metal materials, and is lower in cost.

Description

technical field [0001] The invention relates to a metal derusting cleaning liquid, which belongs to the field of chemical products. Background technique [0002] In the machining process, metal materials are made into mechanical parts, most of which rely on cold working processes. According to the basic size requirements of the parts, cold processing such as turning, drilling, cutting, grinding, etc. is performed on metal plates, bars, wires, profiles, casting blanks, forging blanks, etc. until they are processed to the specified size and accuracy. The processing process is carried out step by step and divided into different types of work. A processing cycle can be as short as a few days, or as long as dozens of days. Sometimes it is temporarily stored in the warehouse during step-by-step processing, and dirt will be generated on the surface of metal parts. It is necessary to clean the surface of metal material parts to remove various dirt attached to the metal surface, su...

AI Technical Summary

Problems solved by technology

After cleaning, the metal surface is exposed to the air and is easy to rust, so it is usually treated with an anti-rust agent during cleaning, which takes a long time and costs a lot

The current process generally adopts cleaning first, and then anti-rust treatment; a few cleaning and anti-rust treatment at the same time, the anti-rust effect is not good, some rust spots appear after a few hours, and rust spots appear after a few days after the anti-rust effect is good
