Coating of water-based paint applied to engineering machinery product

Abstract

The invention provides coating of a water-based paint applied to an engineering machinery product; coating of the water-based paint provided by the invention comprises primers, intermediate paints and finishing paints; the primers comprise single-component primers and double-component primers; the single-component primers comprise a water-based epoxy ester primer, a water-based acrylic acid primer, a water-based polyurethane primer, a water-based inorganic silicate primer and a water-based inorganic zinc-enriched primer (single component); the double-component primers comprise a water-based epoxy primer, a water-based epoxy zinc-enriched primer, a water-based polyurethane acrylate primer and a water-based inorganic zinc-enriched primer; all the intermediate paints are double-component intermediate paints comprising a water-based epoxy mica iron intermediate paint and a water-based polyurethane acrylate intermediate paint; the finishing paints comprise single-component finishing paints and double-component finishing paints; the single-component finishing paints comprise a water-based acrylic acid finishing paint and a water-based polyurethane finishing paint; and the double-component finishing paints comprise a water-based polyurethane acrylate finishing paint. According to the invention, various environment-friendly requirements of the novel environment-friendly method to coating products are solved; simultaneously, the comprehensive properties of engineering machinery required by adopting the traditional oily coating are also optimized; and the coating cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of paint production, in particular to the coating of a water-based paint applied to construction machinery products. Background technique [0002] Under the pressure of smog, the National People's Congress revised the Environmental Protection Law for the first time in 25 years. The revision of the "Environmental Protection Law" was passed, which increased the punishment of large polluters. The amendment clearly stipulates that polluting enterprises can be punished according to the original The amount is continuously punished on a daily basis. With the specific implementation of the revised Environmental Protection Law, the state has severely cracked down on various coating companies. Enterprises that have not carried out rectification according to the plan required by the national environmental protection department have been punished by means of rectification, punishment, and suspension of production. Since 2014, As...

AI Technical Summary

Problems solved by technology

Due to the large construction machinery products and many parts, such as engineering tower cranes, there are many workpieces, so the scope of the spraying site is relatively large, and according to the requirements of the environmental protection department, general enterprises cannot invest more funds to rectify the painting site
