Abstract

The invention discloses waterborne epoxy static electricity conducting anti-corrosion paint, which is prepared from the following method including the steps that 1, water and waterborne dispersing agents are pre-mixed; then, the mixture is added into epoxy resin emulsion to be uniformly stirred; talcum powder, precipitated barium sulphate, titanium dioxide and bentonite are added step by step; high-speed uniform scattering is performed, then, the materials are ground until the fineness is smaller than 50 micrometers; then, the rest waterborne epoxy resin emulsion and the conducting powder are added; the mixture is uniformly stirred; wetting agents are added; the mixture is uniformly stirred; defoaming agents, flatting agents and flash-rust inhibitors are added step by step; diluted waterborne thixotropic agents are added; the materials are uniformly stirred; water is added for regulating the viscosity; an ingredient A is obtained; 2, water and ethyl alcohol are used for proportionally diluting waterborne epoxy curing agents to obtain an ingredient B; 3, the ingredient A and the ingredient B are respectively packaged according to the construction mixture ratio for simultaneously forming the waterborne epoxy static electricity conducting anti-corrosion paint. The paint can be used for the inner wall coating of steel crude oil storage tanks or petrochemical engineering steel intermediate product storage tanks and finished product oil steel storage tanks; obtained coatings have good protection functions of water resistance, oil resistance, chemical medium resistance, salt fog resistance, temperature resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion paint preparation, in particular to a water-based anti-corrosion epoxy electrostatic conductive paint and its preparation method and application. Background technique [0002] Epoxy resin has excellent chemical corrosion resistance and excellent adhesion to steel, and is an excellent anti-corrosion material. Therefore, solvent-based epoxy resin is often used in anti-corrosion primers or intermediate paints for steel protection, and the pre-painted primers made of it are also applied to the surface of other materials; in petroleum and petrochemical anti-corrosion applications, it is used to manufacture various Anti-corrosion primer for steel surface of structural parts, such as: solvent-based epoxy zinc-rich and epoxy mica iron intermediate paint, solvent-based epoxy oil-resistant anti-static anti-corrosion paint for the inner wall of storage tanks, etc. However, with the increasingly stric...
