Environment-friendly waterborne coating used for dip coating of track shoe and preparation method thereof

Abstract

The invention discloses an environment-friendly waterborne coating used for dip coating of track shoe. The environment-friendly waterborne coating is prepared from the following raw materials in percentages by weight: 35 to 50% of a waterborne acrylic modified epoxy emulsion, 0.25 to 0.75% of an antifoaming agent, 1.5 to 3.25% of a dispersing agent, 18 to 28% of deionized water, 0.38 to 0.93% of a neutralizing agent, 0.21 to 0.79% of a leveling and wetting agent, 1.51 to 2.39% of a flash-rust inhibitor, 0.35 to 1.23% of carbon black, 5.23 to 8.36% of iron black, 6.43 to 8.07% of barium sulfate, 6.22 to 8.69% of composite zinc phosphate, 4.31 to 5.57% of a thixotropic anti-settling agent, 3.43 to 5.07% of aluminum tripolyphosphate, 2.43 to 3.27% of talcum powder, 0.33 to 0.67% of matting powder and 0.32 to 0.58% of a thickening agent. The waterborne coating prepared by using the method provided by the invention has the following advantages: the VOC is no more than 85 g / L; the odor is low; the environment is avoided from pollution; meanwhile, the waterborne coating has matte, water resistance, salt fog resistance, excellent surface drying time, stable heat storage performance, and excellent coating film mechanical strength and impact resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environment-friendly water-based track shoe dip coating paint and a preparation method thereof. Background technique [0002] Track shoe is one of the chassis parts of construction machinery, and it is a kind of wearing part of the construction machinery used. Now it is commonly used in construction machinery such as excavators, bulldozers, crawler cranes and pavers. From the material point of view, the track shoes on construction machinery can be divided into two types: steel and rubber. Steel track shoes are mostly used on equipment with relatively large tonnage, and rubber track shoes are mostly used on equipment with small tonnage. Track shoes on steel are mainly studied here. In recent years, with the rapid development of my country's industry, the construction machinery production industry has risen and grown rapidly. While driving the development of the track shoe industry, it...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, domestic track shoe coatings mainly have the following technical bottlenecks: 1. The existing paints are mainly solvent-based, and the problem of high VOC content and serious pollution in paint needs to be solved; 2. Even water-based coatings also have high VOC content. Big smell, environmental pollution and other problems; 3. Existing solvent-based coatings have some problems such as hardness and poor adhesion, and there is still a certain gap between the hardness and adhesion of existing water-based coatings compared with solvent-based products
