Abstract

The invention provides a high-performance two-component epoxy primer for rail transit and a preparation process thereof, belonging to the technical field of paints. The high-performance two-componentepoxy primer comprises a component A and a component B in a weight ratio of 10: (2.3-2.8). The component A is prepared from the following components: solid epoxy resin, liquid epoxy resin, graphene, epoxy silane coupling agent modified nanometer silicon dioxide, pigment and filler, zinc-calcium modified aluminum triphosphate, zinc phosphomolybdate, a thixotropic agent, a wetting dispersant, a leveling agent, an antifoaming agent and a mixed solvent. The component B is prepared from cashew nut shell oil modified phenolic aldehyde amine resin, cardanol modified polyamide resin, xylene, n-butyl alcohol, propylene glycol methyl ether acetate and an amino silane coupling agent. The epoxy primer prepared by the invention has excellent mechanical properties, corrosion resistance, weather resistance and adhesive force, and has good application prospects in rail transit.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance two-component epoxy primer for rail transit and a preparation process thereof. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, more and more types of rail transit have emerged, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. [0003] According to the difference in service scope, rail transit is generally divided into three categories: national railway system, intercity rail transit and urban rail transit. Rail transit generally has the advantages of large transportation volume, fast speed, frequent shifts, safety and co...
