Abstract

The invention discloses an environment-friendly oily antirust paint composed of the following components by the weight percentage: 40-50% of an oily acrylic emulsion, 10-30% of an antirust pigment, 20-30% of an extender pigment, 10-20% of an oily curing agent, 0.5-1% of a defoaming agent, 0.5-1.5% of a dispersing agent, 0.1-0.5% of a levelling agent, 0.1-0.5% of a rheological auxiliary agent, and 0.5-2% of an anti flash rust agent. The environment-friendly oily antirust paint has the beneficial effects that the environment-friendly oily antirust paint has less content of volatile organic matters and small environmental pollution, has quite important practical significance on energy conservation, emission reduction, low carbon and environmental protection, and can be widely used in automotive coating.

Description

technical field [0001] The invention relates to a coating, in particular to an environment-friendly oily antirust paint. Background technique [0002] At present, with the development of my country's automobile industry, my country's automobile production has increased rapidly in recent years, and China has become the world's largest automobile consumer. The steel plates of these products need to be painted to prevent rust and improve the appearance. The development of the automobile industry has also made great progress in automobile coating technology. At the same time, automobile coatings have also made great progress. However, at present, my country's automotive coatings are still dominated by oily solvent-based systems, which contain a large amount of volatile organic compounds, which pollute the environment very seriously. Therefore, it has become a technical problem to be solved in the industry to provide an environmentally friendly oil-based antirust paint with les...
