Abstract

The invention discloses a self-lubricating water-based environment-friendly coating. The water-based environment-friendly coating is composed of the components in percentage by mass: 20%-40% of A, 15%-25% of B, 10%-20% of Al powder and Zn powder, 1%-3% of an organic silicon defoamer, 2%-8% of a corrosion inhibitor, 1%-5% of a cosolvent, 10%-20% of a lubricant and 10%-15% of water, wherein the A isa reaction product of rosin and a silane coupling agent, and the B is a reaction product of ZrCl4, quaternary ammonium salt and tripolyphosphate in triethanolamine. A preparation method comprises thesteps: weighing the A and the B, and uniformly stirring; and adding the Al powder, the Zn powder, the organic silicon defoamer, the corrosion inhibitor, the cosolvent, the lubricant and water, and fully stirring and uniformly mixing to obtain the coating. The coating has excellent corrosion resistance, self-lubricating property, film-forming property, passivation property, slow release property and the like.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a self-lubricating water-based environmental protection coating and a preparation method and application thereof. Background technique [0002] Fasteners are an important component in industry and are widely used in various industries. From general infrastructure, such as electric towers, signal towers, etc., to cutting-edge industries are essential components, such as aerospace, aviation. It is a metal material widely used in engineering, and in the use of metal materials, special attention should be paid to its corrosion problem. If it is not protected, it will be damaged by corrosion, causing economic losses in the slightest, and safety accidents in the worst case. In the past, chromium-containing material coating, galvanizing, and phosphating were often used for anti-corrosion of fasteners to make them corrosion-resistant and long-lasting, and play a key role in protectin...
