Environmental protection coating for square air pipe check valves

Abstract

The invention relates to the field of environmental protection coatings, in particular to an environmental protection coating for square air pipe check valves. The environmental protection coating isprepared from the following raw materials in parts by weight: 10-30 parts of sodium alginate, 10-30 parts of calcium oxide, 3-5 parts of butanedione, 5-8 parts of gypsum powder, 1-8 parts of megilp, 1-3 parts of propylene glycol, 5-8 parts of zeolite powder, 1-5 parts of cesium oxide, 30-50 parts of water and 30-50 parts of additives. The environmental protection coating disclosed by the inventionis reasonable in raw material formula and easy in obtaining of raw materials; the product has the characteristics of being bright in color, damp-proof and oil-proof, absorbing ultraviolet light, being flame-retardant, and the like; furthermore, non-toxic and harmless products are used for processing and producing the environmental protection coating, so that the environmental protection coating is environmentally-friendly, free from pollution and in line with the current social development.

Description

technical field [0001] The invention relates to the field of environmental protection coatings, in particular to an environmental protection coating for square air duct check valves. Background technique [0002] Check valve refers to the valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is a kind of automatic valve, its main function is to prevent the reverse flow of the medium, the reverse rotation of the pump and the drive motor, and the discharge of the container medium. The function of this type of valve is to only allow the medium to flow in one direction and prevent the flow in the opposite direction. Usually this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the valve...

Problems solved by technology

[0003] In the current society, the coatings used have great shortcomings. Generally speaking, most of the existing paints and coatings contain harmful gases such as formaldehyde, which have great harm to the human body, pollute the air, and do not conform to the current environmental protection concept.
