Abstract

The invention provides a flame-retardant and anti-corrosive coating applied to aluminum alloy surface and resistant to multiple highly corrosive media. The flame-retardant and anti-corrosive coating contains a component A and a component B, wherein the component A is prepared from ingredients in percentage by weight as follows: 10%-60% of inorganic matter modified epoxy resin, 22%-45% of filler and pigment, 3%-5% of a flame retardant, 1%-5% of an auxiliary I and 10%-25% of a solvent; the component B is a modified resin curing agent and is prepared from ingredients in percentage by weight as follows: 5%-15% of modified alicyclic amine resin, 20%-40% of phenolic aldehyde amine resin, 25%-35% of filler, 1%-5% of an auxiliary II and 10%-30% of a solvent; during using, the component A and the component B in a weight ratio being 2:1-8:1 are mixed uniformly and used up within 3 h. The invention further provides a preparation method and an application of the flame-retardant and anti-corrosive coating. The flame-retardant and anti-corrosive coating is applied to the aluminum alloy surface and resistant to multiple highly corrosive media, has excellent salt fog resistance, salt water resistance, flame retardancy and film-forming property, produces no by-products during preparing and does not need aftertreatment, so that the technological method is simple and convenient, energy is saved, and the cost is low.

Description

technical field [0001] The invention belongs to the field of anti-corrosion, and in particular relates to a flame-retardant anti-corrosion coating for the surface of aluminum alloys resistant to various strong corrosive media, a preparation method and an application. Background technique [0002] With the continuous development of the national economy and basic construction, national key projects and large-scale projects have higher and higher requirements for anti-corrosion. Aluminum alloy surfaces have higher requirements for coatings, especially in severe corrosive environments. It has excellent corrosion resistance, can withstand the corrosion of various media, and has flame retardant properties. As we all know, it is necessary to choose flame-retardant materials out of fire safety considerations. At the same time, corrosion is a kind of damage that is quietly going on. According to statistics, the major economic losses and huge waste of resources and energy caused by co...
