Abstract

The invention discloses a preparation method of a high-temperature-resistant coating material for a liquid-state light hydrocarbon gasification device, and relates to the technical field of coating materials, wherein the prepared high-temperature-resistant coating material has high high-temperature resistance, can ensure that a coating film does not crack at a high temperature of 460 DEG C, and isexcellent in hardness and adhesive force. According to the preparation method, treating is performed by utilizing excessive maleic anhydride to carry out an esterification reaction with the hydroxylon the surface, so that the maleic anhydride is grafted to the surface of boehmite; the boehmite grafted with the maleic anhydride reacts with heptaphenyl silsesquioxane trisilanol, so that the heptaphenyl silsesquioxane trisilanol is combined with the boehmite through the maleic anhydride to obtain a boehmite-heptaphenyl silsesquioxane trisilanol complex; and the hydroxyl on the heptaphenyl silsesquioxane trisilanol and the hydroxyl of an epoxy resin are subjected to a condensation reaction, so that the cross-linking degree is improved, the adhesive force of a coating film is improved, and the high-temperature resistance of the epoxy resin is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a method for preparing a high-temperature-resistant coating for a liquid light hydrocarbon gasification device. Background technique [0002] The liquid light hydrocarbon gasification device is a device that gasifies light hydrocarbon light oil and mixes it with air in a certain proportion to form a mixed gas for people to use. The light hydrocarbon light oil used for gas production is mainly C5 (carbon five), C6 (carbon six) and C7 (carbon seven). Because heating is required during the gasification process, the gasification device usually includes a heating device, but during use, due to prolonged heating, the paint film on the outer surface of the device often falls off, affecting its appearance and service life. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a method for preparing high temperature resistant coatings ...
