Efficient paint fog coagulant, preparation method thereof and application

Abstract

The invention discloses an efficient paint fog coagulant, a preparation method thereof and an application. The paint fog coagulant comprises a tack-free agent, a slow-release floating agent and a pH (potential of hydrogen) value regulating agent. The tack-free agent comprises a component a, a component b and a component c, wherein the component a is water-soluble cationic polymer, the component b is amphoteric metal salt and / or amphoteric metal salt polymer, and the component c is a surface active agent. The slow-release floating agent comprises anionic polymer, citric acid, sodium bicarbonate, sodium carbonate, mannitol and polyethylene glycol. The paint fog coagulant is applied to wet paint fog system circulating water and simple in use method, and over-spraying paint in the water can be efficiently and rapidly debonded, condensed and floated, so that the circulating water is conveniently reused. By the aid of the paint fog coagulant, painting operation environments can be effectively improved, water quality can be improved, circulating water efficiency is increased, the replacement frequency of the circulating water is reduced, and enterprise cost is saved.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a paint mist coagulant and a preparation method and application thereof. Background technique [0002] During the painting process of electronic products, engineering machinery, auto parts, motorcycles and other industries, about 20-60% of the paint is not attached to the device. This part of the paint is called overspray paint. These paints contain a large amount of volatile organic Solvents affect the health of operators and seriously pollute the surrounding air and environment, so they need to be cleaned up in time. For this reason, the painting industry usually uses a wet spray booth circulating water system to capture overspray paint. In this way, the overspray paint and organic solvent can be brought outdoors by the water circulation of the indoor sink and the outdoor sink, reducing the health impact on the operators, while the overspray paint will adhere to the walls of the sink, p...

Problems solved by technology

However, due to their strong acidity, citric acid and oxalic acid are easy to corrode the circulating water equipment on the one hand; on the other hand, they cannot make the paint float up, but will deposit at the bottom of the circulating pool, making dredging difficult and increasing the cost of use

Although the AB agent can solve the problems existing in the use of citric acid and oxalic acid, it has the disadvantages of long operation steps and long time consumption.
