Abstract

The invention discloses a treating agent for the inner wall of a valve. The treating agent for the inner wall of the valve is prepared from the following raw materials in parts by weight: 60-80 partsof a polyacrylamide emulsifier, 10-15 parts of waterborne acrylic resin, 10-15 parts of cresol formaldehyde epoxy resin, 5-10 parts of a dispersing agent, 0.5-1.5 parts of a thickening agent, 1-2 parts of a defoaming agent, 1-2 parts of nano silicon dioxide and 1-2 parts of iron trioxide. Due to the technical scheme, the treating agent for the inner wall of the valve has the beneficial effects that the treating agent is excellent in physical and chemical property and good in weather fastness, has high transparency, excellent anti-rust property, oil-proof property, waterproof property, saline-water-proof property and solvent-proof property, is good in adhesive force, and does not cause environmental pollution.

Description

technical field [0001] The invention relates to a treatment agent, in particular to a valve inner wall treatment agent. Background technique [0002] During the production process of the valve, since the inner wall of the valve is in contact with the transported liquid, and most of these liquids are corrosive and polluting, the inner wall needs to be treated with anti-rust and anti-pollution treatment. The currently used treatment agent has the following defects: [0003] 1. Low adhesion, easy to crack and drop, resulting in short service life; [0004] 2. The ability of weather resistance, moisture resistance and corrosion resistance is weak, and it is easy to be corroded when it comes into contact with the liquid being transported, so that it will fall off and pollute the liquid. Contents of the invention [0005] The technical problem to be solved by the invention is to provide a valve inner wall treatment agent. [0006] In order to solve the above technical problems...
