Abstract

The invention discloses an epoxy resin coating with high acid and alkali resistance, relates to the chemical industry field, and mainly solves the problem of poor acid and alkali resistance of traditional epoxy resin coatings. The coating comprises the following raw materials in pats by weight: 78-91 parts of epoxy resin, 11-19 parts of vermiculite, 3-7 parts of kaolinite, 1.3-2.6 parts of a preservative, 0.9-1.7 parts of a thickening agent, 6-14 parts of a rosin emulsion, 7-13 parts of a rhinoceros horn extraction liquid, and 14-23 parts of black fish bone. The coating adopts a reasonable formula, under the synergistic action of various raw materials, especially under the action of synergistic components of the rhinoceros horn extraction liquid and the black fish bone, the acid and alkaliresistance of the coating can be effectively enhanced, paint-spraying objects are prevented from high temperature chemical corrosion, and the service life of components is prolonged.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an epoxy resin coating with high acid and alkali resistance and a preparation method thereof. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] Epoxy resin paint is a coating with epoxy resin as the main film-forming substance. There are many types, each with its own characteristics. According to the curing method, there are self-drying single-component, two-component and multi-component liquid epoxy coatings; baking single-component and two-component liquid epoxy coatings; powder epoxy coatings and radiati...
