Abstract

The invention provides a graphene modified fluorosilicone anti-corrosive and wear-resistant coating and a preparation method thereof, and relates to the field of organic polymer materials. According to the graphene modified fluorosilicone anti-corrosive and wear-resistant coating and the preparation method thereof, the graphene modified fluorosilicone anti-corrosive and wear-resistant coating comprises a component A and a component B, the mass ratio of the component A to the component B is (95-105): (35-50), the component A is prepared from the following raw materials in parts by mass: 32.5-68.5 parts of mixed epoxy resin, 25-56 parts of wear-resistant filler, 0.5-2 parts of nano graphene, 1-5 parts of a silane coupling agent and 2-10 parts of a mixed solvent, and the component B is prepared from the following raw materials in parts by mass through addition reaction: 8.5-12.5 parts of plant polyenol, 8.5-12.5 parts of diethylenetriamine and 15-25 parts of triethylenetetramine. By adopting the mixed epoxy resin, stress relief, adhesive force and corrosion resistance are improved. Meanwhile, the corrosion resistance and permeation resistance of the coating are greatly improved through the lamellar structure of the graphene, and therefore the purpose of corrosion resistance is achieved, and the coating is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the field of organic polymer materials, in particular to a graphene-modified fluorosilicon anti-corrosion and wear-resistant coating and a preparation method thereof. Background technique [0002] For brick or concrete and steel-lined chimneys used in thermal power plants, chemical and metallurgical industries, anti-corrosion treatment is an important project, and in the internal structure of the chimney, some special parts need special anti-corrosion treatment, such as horns and The ash accumulation platform and the inner and outer corners, due to the combined effect of the stress generated by the expansion and contraction in the horizontal and vertical directions, will lead to the damage of the anticorrosion layer, the failure of the anticorrosion, the leakage of condensate, and the leakage of the anticorrosion at the ash accumulation platform and the inner and outer corners. Leakage is a common phenomenon in chimneys after a...
