Problems solved by technology

The anti-corrosion materials on the surface of the equipment usually use organic polymer materials, which have good anti-corrosion properties. However, the coatings of these materials are thin, expensive and have weak impact resistance, and these coating materials will be damaged by ultraviolet radiation and weathering. Its life is shortened, and the cost of cumulative consumption is higher

Abstract

The invention belongs to the technical field of coatings, and particularly relates to a cement-based composite anticorrosive coating. The cement-based composite anticorrosive coating is a solid-liquidtwo-phase two-component composite material and is prepared by mixing a liquid-phase component and a solid-phase component; wherein the liquid-phase component is prepared from, by weight, 10%-30% of epoxy emulsion, 30%-40% of water and 1-5% of admixture; the solid-phase component is prepared from, by weight, 15%-30% of cement, 5%-15% of quartz sand, 1%-2% of cellulose, 0.5%-1. 5% of zinc powder and 0.5%-1. 5% of titanium oxide. The coating formed by mixing the solid phase and the liquid phase has anti-corrosion properties and the effects of impact resistance and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a cement-based composite anticorrosion coating. Background technique [0002] In steel structures, bridges, storage tanks, marine engineering and other fields, the corrosion protection of equipment is one of the difficulties to be solved at present. The anti-corrosion materials on the surface of the equipment usually use organic polymer materials, which have good anti-corrosion properties. However, the coatings of these materials are thin, expensive and have weak impact resistance, and these coating materials will be damaged by ultraviolet radiation and weathering. Its life is shortened, and the cost of cumulative consumption is higher. Therefore, it is of great significance for sustainable development to develop a kind of corrosion-resistant, impact-resistant, low-cost, environmentally friendly anti-corrosion coating. Contents of the invention [0003] The purpose of the pr...
