Abstract

The invention relates to fast-dry solvent type intermediate epoxy resin paint, which comprises a main agent and a curing agent, wherein the ratio of the main agent to the curing agent is between 20 to 1 and 5 (weight). Compared with the prior art, the intermediate epoxy resin paint has good drying property as well as simple and convenient coating operation, adapts to flow coating of the prior containers, can be thickly coated to the specified film thickness at one time, has good anticorrosion property, and has good binding force with a last-pass primer and a next-pass primer; and for thicker outer finish, particularly polyurethane finish, the intermediate epoxy resin paint has good usability, can not froth, and has good anticorrosion property.

Description

technical field [0001] The invention relates to a non-aqueous medium epoxy resin intermediate paint suitable for container exterior coating, in particular to a fast-drying solvent-type epoxy resin intermediate paint. Background technique [0002] At present, the container manufacturing industry is mainly concentrated in China. China has brought together more than 80% of the global container manufacturing activities. As the world's coating industry is accelerating its transfer, my country, as one of the world's largest coating production countries, has taken the lead in the development of the container industry. The field of container coatings has achieved a leading position. Since 1994, China's container export volume has ranked first in the world. So far, China's container industry has dominated the world for eight consecutive years, with an average growth rate of 25%. The container is an international means of transportation between the inland and the sea. Therefore, the c...
