High-temperature-resistant coating containing hydantoin epoxy resin and preparation method of high-temperature-resistant coating

Abstract

The invention discloses a high-temperature-resistant coating containing hydantoin epoxy resin. The coating comprises a component I and a component II, wherein the component I is blended by a component A and a component B, the component A comprises ingredients as follows: the hydantoin epoxy resin, filler, a dispersing agent, an auxiliary, a coalescing agent, a thickening agent and a defoaming agent, and the component B comprises ingredients as follows: grafted organic silicon resin, a thixotropic agent, a matting agent, antimonous oxide, an auxiliary and a mildew preventive; the component II comprises components as follows: a curing agent, a coupling agent and a solvent. The invention further designs a preparation method of the high-temperature-resistant coating containing the hydantoin epoxy resin. The preparation method is simple to operate and low in cost, and the prepared coating has excellent high temperature resistance and high adhesive force, and is non-poisonous and pollution-free.
