Cleaning rust remover and preparation method thereof

Abstract

The invention provides a cleaning rust remover. The cleaning rust remover comprises, by weight, 15-25 parts of 85wt% phosphoric acid, 8-12 parts of long-oil alkyd resin, 5-10 parts of sodium gluconate, 2-5 parts of triethanolamine, 2-8 parts of polyaspartic acid, 0.15-0.30 part of oxidized starch, 8-12 parts of trimethyl cetyl ammonium bromide, 60-80 parts of water, 8-15 parts of lauryl sodium sulfate and 5-12 parts of sodium tripolyphosphate. The invention further provides a preparation method of the cleaning rust remover. According to the cleaning rust remover, cleaning, phosphorous removal,rust removal, corrosion prevention and rust prevention of the surface of ferrous metal can be accomplished at the same time only by one procedure, and a plurality of procedures are reduced for ferrous metal surface treatment, so that the substrate of the ferrous metal surface is prevented from being excessively acidized.

Description

technical field [0001] The invention relates to the field of chemical cleaning agents, in particular to a cleaning and derusting agent for ferrous metal surfaces. Background technique [0002] Ferrous metals refer to iron, manganese, chromium and their alloys, such as steel, pig iron, iron alloys, cast iron and other ferrous metals. After cleaning, in order to prevent surface corrosion, antirust treatment must be carried out, such as applying antirust agents on the surface. In the prior art, anti-rust oil with better anti-rust effect was used earlier, and a protective oil film was formed on the metal surface through the anti-rust oil to isolate the corrosion of metal by water vapor in the air, so as to achieve long-term anti-rust. However, the use of anti-rust oil not only consumes a large amount of oil raw materials, which intensifies energy consumption, but also requires further cleaning during subsequent processing, which not only produces a large amount of waste liquid d...

Problems solved by technology

However, the use of anti-rust oil not only consumes a large amount of oil raw materials, which intensifies energy consumption, but also requires further cleaning during subsequent processing, which not only produces a large amount of waste liquid discharge, but also causes environmental pollution, and the second phase of cleaning and degreasing costs Time-consuming and cost-intensive, therefore, there is an urgent need for a rust remover that can simultaneously complete cleaning, phosphorus removal, rust removal, anti-corrosion and rust prevention
