Problems solved by technology

However, this technology still has certain shortcomings, that is, when spraying paint with water-based baking paint in the air pressure-water washing spray booth, the paint residue is easy to precipitate in the circulating water, making it difficult to separate the paint residue from the circulating water. The water is lighted, and then the pool bottom paint residue is precipitated and cleaned

Abstract

The invention discloses an efficient paint spraying circulation water treatment agent as well as a preparation method and a use method thereof. The paint spraying circulation water treatment agent is prepared from an agent A, an agent B, an agent C and an agent D, wherein the agent A is prepared by reacting polyacrylic acid and ammonia water; the agent B is composed of amide-based polymer and water at a weight ratio of 1: (100-120); the agent C is prepared by mixing a compound Y with a compound Z at a weight ratio of 1: 1; the compound Y is composed of polyaluminum chloride and disodium ethylenediamine tetraacetate; the compound Z is composed of sodium citrate and sodium pyrophosphate; the agent D is prepared by mixing potassium hydroxide, sorbitan fatty acid ester and water at a weight ratio of 1: (2-3): (1-2); the agent A, the agent B, the agent C and the agent D can be prepared respectively; when in use, the agent A, the agent B, the agent C and the agent D are added in sequence, wherein the weight ratio of the agent A to the agent B to the agent C to the agent D is 5: 5: 1: 1. The paint spraying circulation water treatment agent provided by the invention has strong viscosity breaking capacity and enables the paint to be completely not sticky.

Description

Technical field [0001] The invention relates to the technical field of spray paint circulating water treatment, in particular to a spray paint circulating water treatment agent, a preparation method and a use method thereof. Background technique [0002] When painting in the spray booth, in order to prevent the overspray (without the work piece) from scattering, the spray mist is treated by water curtain or water spinning, so that the overspray paint will float in the circulating water. But this alone will cause pipeline blockage and overload operation of the circulating pump, which directly leads to a reduction in work efficiency or even shutdown. In addition, the cleaning operation of the circulating pool is extremely difficult, laborious, and inconvenient to continuous production. Therefore, the method of adding chemical agents to the spray paint circulating water is usually used, so that the over spray paint in the circulating water produces a condensation and floating effec...
