Abstract

The invention discloses a high-flash-point safe epoxy micaceous iron intermediate coating and a preparation method thereof, the epoxy zinc-rich primer comprises a paint component and a curing agent component, and is characterized in that the paint component is prepared from the following raw materials in percentage by mass: 15-40wt% of high-flash-point epoxy resin, 15-40wt% of high-flash-point epoxy resin, 15-40wt% of high-flash-point epoxy resin, 15-40wt% of high-flash-point epoxy resin, 10-40wt% of high-flash-point epoxy resin 8 to 23 wt% of ethylene glycol butyl ether acetate; 0.2 to 1 wt% of polyamide wax; 0.1 to 1 wt% of organic bentonite; 10 to 30 weight percent of talcum powder; 20 to 40 wt% of mica iron oxide; the curing agent component is prepared from the following raw materials: 10-50wt% of butyl cellosolve acetate; 15 to 20 weight percent of phenolic aldehyde ammonia; 3 to 10 weight percent of high-flash-point epoxy resin; and 20-50 wt% of modified polyamide. According to the invention, compared with the conventional epoxy micaceous iron oxide intermediate coating, the dangerous problems of safety, environmental protection, transportation, use and the like can be thoroughly solved, and the corrosion resistance and shielding property of the epoxy micaceous iron oxide intermediate coating are improved by 2-3 times compared with those of the same type of products in the current market.

Description

technical field [0001] The invention belongs to the field of anti-corrosion coatings, in particular to a high flash point safe epoxy mica intermediate coating and a preparation method thereof. Background technique [0002] At present, the materials used in the formulation of epoxy micaceous iron intermediate coatings on the market are all made of conventional oily organic materials. The formulation design has problems such as low flash point, unenvironmental protection, flammability, and poor storage safety. Therefore, it is necessary to try to prepare a high Flash point safe epoxy micaceous iron intermediate coating.
