Problems solved by technology

However, this method has the following limitations: this method of rust removal requires spraying equipment costing millions of dollars, it is inconvenient to operate steel parts over 1.6 meters long, and it is not easy to remove the corners of complex components, so it is not suitable for thin walls Steel, and the environmental pollution
However, this method has the following limitations: However, this rust removal method is not thorough in rust removal, and it is not easy to remove the corners and welded parts of the components. The labor intensity is high, time-consuming and laborious, and rust will often reappear in a short period of time.
[0005] At room temperature, the raw steel sold on the market will rust after 3-5 days of polishing. Although it can be used after polishing, the accuracy is biased due to wear and tear.

Abstract

The invention provides an attapulgite-containing mechanical antirust paint and a preparation method thereof. The antirust paint comprises 22-27 parts of water-soluble phenolic resin, 15-20 parts of a polyurethane-polyacrylate composite emulsion, 18-22 parts of attapulgite, 7-9 parts of sodium carbonate, 1.0-1.5 parts of triethanolamine, 18-22 parts of polycaprolactone, 0.1-0.3 part of polybutylene terephthalate, 0.7-0.9 part of potassium chloride, 0.4-0.6 part of 2,6-2-tert-butyl-alpha-dimethylamino-p-phenol, 1.5-2.5 parts of a modified acrylic emulsion, 0.5-0.8 part of chitosan, 3-6 parts of cottonseed oil, 5-8 parts of benzyl cinnamate and 8-10 parts of a modifying assistant. The antirust paint has the advantages of good adhesion, fastness in drying, good heat resistance, environmental protection and no pollution; attapulgite and the modifying assistant are added to raw materials, and are modified to improve the performances of polymeric materials in the raw materials and increase the resistance to corrosion and heat.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering materials, in particular to an antirust paint for machinery containing attapulgite and a preparation method thereof. Background technique [0002] Most of the components and structures of mining machinery are made of steel, and steel is prone to rust when exposed to the atmosphere, and the surface turns into loose rust, which affects the normal use of the machinery and reduces work efficiency. The existing rust removal methods are as follows: [0003] 1. Mechanical shot blasting or sand blasting: that is, the steel shot or sand is sprayed onto the surface of the rusted steel by high-pressure gas to wear off the rust. However, this method has the following limitations: this method of rust removal requires spraying equipment costing millions of dollars, it is inconvenient to operate steel parts over 1.6 meters long, and it is not easy to remove the corners of complex components, so i...
