Problems solved by technology

At present, oil-based paint (chlorinated rubber anti-corrosion coating) is used in the painting of export trucks and vehicles. It has high VOC content, high toxicity, pollutes the environment, and damages human health. It is forbidden to use oil-based paint to paint various types of trucks and vehicles abroad.
Foreign companies have higher requirements on the performance index of water-soluble paint, and the existing water-soluble paint cannot meet the requirements
At present, there is no water-soluble paint that can meet the requirements of export trucks and vehicles

Embodiment Construction

[0021] Water-soluble paint for railway export freight cars, which is made by mixing component A and component B in a ratio of 4:1; component A is composed of the following raw materials by weight: water-based acrylic modified polyurethane resin 60; dispersant 0.5; wetting Agent 0.35; Defoamer 0.15; Neutralizer 0.1; Pigment Titanium Dioxide 15; Talc 12; Thickener 0.2; Antirust Agent 10; Water 1.7; Component B is used as crosslinking curing agent using water-based polyisocyanate.

[0022] The preparation method of water-soluble paint for railway export freight cars is realized by the following steps:

[0023] Preparation of component A:

[0024] 1) Add the water-based acrylic modified polyurethane resin, dispersant, wetting agent, defoamer, and neutralizer into the pull tank according to the stated proportions, and stir slowly for 10-15 minutes (for specific implementation, you can choose 10, 11 , 12, 13, 14, 15 minutes), then add the titanium dioxide, talcum powder, and rust inhibito...

Abstract

The invention relates to a water-soluble paint, in particular to a water-soluble paint for railway export trucks and vehicles. It solves the problem that there is no water-soluble paint that can meet the requirements of export trucks and vehicles. The water-soluble paint is prepared by mixing component A and component B at a ratio of 4:1; component A is composed of the following raw materials in parts by weight: water-based acrylic modified polyurethane resin 60; dispersant 0.5; wetting agent 0.35; Foaming agent 0.15; neutralizing agent 0.1; pigment titanium dioxide 15; talcum powder 12; thickener 0.2; rust inhibitor 10; water 1.7; The various performances of the water-soluble paint of the invention can reach or exceed the standard of the oil-based paint currently used on export trucks and vehicles. In addition to being specially used for railway export wagons, it can also be used in other fields.

Description

Technical field [0001] The invention relates to a water-soluble paint, in particular to a water-soluble paint for railway export freight cars. Background technique [0002] The surface of railway freight cars shall be painted with paint as a whole for the anti-corrosion, anti-rust, and ultraviolet (anti-aging) of freight cars. At present, oil-based paint (chlorinated rubber anticorrosive paint) is used for the coating of exported trucks, which has high VOC content, high toxicity, pollutes the environment, and harms human health. It is prohibited to use oil-based paint to paint various types of trucks and vehicles abroad. Foreign businessmen have higher requirements for the performance indicators of water-soluble paints, and the existing water-soluble paints cannot meet the requirements. At present, there is no water-soluble paint that can meet the requirements of export trucks. Summary of the invention [0003] In order to solve the problem that there is no water-soluble paint t...
