Abstract

The invention discloses a composite coating layer material, which comprises a component A and a component B, wherein the component A is composed of epoxy resin, anti-wear and anti-corrosion micro powder, a coupling agent, a reactive diluent, a thixotropic agent and a defoaming agent, and the component B consists of the following components: a curing agent, a curing accelerator and an adhesion promoter. According to the invention, the composite coating layer material has the advantages of high flexibility, mechanical strength, bonding strength, corrosion resistance, wear resistance, weather resistance, long storage stability, low viscosity, no warping, no shedding, no cracking, and long service life; the composite coating layer material does not contain volatile organic solvents, and the cured coating has no pinholes, does not shrink, is hard, and is relatively safe to the environment and constructors; the preparation process is simple, construction operation is easy and convenient, construction can be conducted at the normal temperature, curing can be conducted at the normal temperature, shape suitability is high, the thickness of the coating is controllable, machining can be achieved, and the coating can be applied to various base materials; and the raw materials are easily available and low in cost.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite coating material. Background technique [0002] Corrosion, especially the dual effect of wear and corrosion is one of the main forms leading to the failure of equipment facilities and structural parts. For pipelines conveying high-speed fluids (such as gas, liquid and powder), corrosion and wear are in a vicious cycle, and wear is accelerated. Corrosion aggravates wear; for pipelines, piles, platforms, steel structures, storage tanks, etc. The corrosion and erosion of equipment and facilities are even more worrying. Therefore, there is an urgent need for functional materials with excellent comprehensive properties such as high performance, composite, long life, corrosion resistance, and wear resistance to protect the surfaces of these facilities for long-term protection. Make sure it can serve for a long time. [0003] At present, there are many ways to ...
