Abstract

The invention relates to the field of high-temperature acidic flue gas corrosion protection of metal and inorganic building materials, and in particular, relates to a high-temperature-resistant graphene / vinyl-based resin anticorrosive coating and a preparation method thereof. A graphene / vinyl-based resin masterbatch with the graphene content of 10 wt% is added to vinyl-based resin, then a diluent and an auxiliary agent are added and stirred to be uniformly dispersed, and a component A is formed; a component B is a curing agent, and a component C is a curing accelerator. According to the weight percentage, the component A accounts for 52.8-92.7% of, the component B accounts for 3.3-33.0%, and the component C accounts for 3.1-24.7%. In the component A, the content of graphene is in a range of 0.064-4.7 wt%. The graphene / vinyl-based resin anticorrosive coating is prepared by mixing and stirring evenly the three components; after the coating is coated and dried by a conventional method, a corrosion protection coating layer resistant to high-temperature acidic flue gas corrosion can be prepared. Compared with the prior art, the prepared graphene composite coating layer can take high-temperature resistance, acid resistance and HF corrosion resistance into account, and the comprehensive performance of the coating is superior to that of a conventional glass flake composite coating.

Description

technical field

[0001] The invention relates to the field of high-temperature acid flue gas corrosion protection for metal and inorganic building materials, in particular to a high-temperature-resistant graphene / vinyl resin anti-corrosion coating for flue anti-corrosion with high-temperature flue gas corrosion resistance and a preparation method thereof. Background technique

[0002] In my country's energy structure, the proportion of coal-fired thermal power generation accounts for about 70%. Thermal power plants mainly use high calorific value coal, and more than 50% of the coal is bituminous coal, followed by lean coal, and anthracite only accounts for less than one-tenth. The coal combustion process produces a large amount of silicon-calcium dust, and at the same time emits a large amount of acid gas mainly composed of sulfur dioxide and compounds containing fluorine, chlorine, and nitrogen elements. These dusts and gases will cause huge chemical corrosion and physical ...
