Abstract

The invention discloses an anticorrosive acid and alkali resistant acrylic coating and a preparation method thereof. The acrylic coating is prepared from the following raw materials in parts by mass: 70 to 80 parts of butanol, 50 to 60 parts of butyl acetate, 20 to 30 parts of butyl acrylate, 20 to 30 parts of acrylic acid, 20 to 30 parts of hydroxyethyl acrylate, 20 to 30 parts of methyl methacrylate, 0.1 to 0.3 part of azodiisobutyronitrile, 0 to 14 parts of hexafluorobutyl methacrylate, 10 to 12 parts of epoxy resin, 10-12 parts by mass of a cross-linking agent and 0.1-0.4 part by mass of a catalyst. The acrylic coating is excellent in corrosion resistance, acid resistance and alkali resistance, simple and convenient in process, non-toxic and harmless, and excellent in economic value.

Description

technical field [0001] The present invention relates to the technical field of acrylic paints. Background technique [0002] Stainless steel materials are the basic building materials for a country's economic development. They are widely used in various fields and are playing an increasingly important role. In the actual application process, the application effect of stainless steel is often related to the surface treatment process and coating protection technology it has undergone. In the actual production and living environment, under the continuous erosion of various acids, alkalis and humid conditions, the surface of stainless steel will produce various aging and corrosion. The resulting safety hazards and even vicious accidents emerge in endlessly. After stainless steel corrodes, even replacing stainless steel materials will cause a great waste of resources. Therefore, it is of great significance to the healthy and sustainable development of the national economy to re...
