Abstract

The invention discloses high-solid solvent type antiseptic 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 antiseptic epoxy resin paint has high mass solid content and lower content of organic volatile substances, can adapt to flow coating of the prior container, can be thickly coated to the specified film thickness at one time, has good anticorrosion property and good physical and mechanical properties such as shock resistance, wear resistance, a paint film has no toxicity and can contact foodstuff such as grain and other food materials, and the antiseptic epoxy resin paint passes the performance detection of Food and Drug Administration (USA) and achieves the corresponding authorization certificate.

Description

technical field [0001] The invention relates to a non-aqueous medium finish paint suitable for the inner coating of a container, in particular to a high-solid solvent type epoxy resin anticorrosion 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. However, the development of the container industry has also brought about environmental problems, and container manufacturers are constantly being asked to move to remote areas. Various low-pollution coatings have emerged at the historic moment since the 1970s, and one of the better effects is high-solid coatings. ...
