Spray paint circulating water treatment agent, preparation method and application method thereof

Abstract

The invention provides a paint spraying circulating water treatment agent, a preparation method and a use method. The paint spraying circulating water treatment agent is prepared from an agent A, an agent B and an agent C, wherein the agent A is prepared from polyacrylic acid and ammonia water through a reaction; the agent B is prepared from amide polymers and water in a weight ratio being 1:(100-120), and molecular weight of the amide polymers is 18,000,000-30,000,000; the agent C is prepared from a compound Y and a compound Z through mixing, and a weight ratio of the compound Y to the compound Z is 1:1; the compound Y is prepared from polymeric aluminium and disodium ethylenediamine tetraacetate; the compound Z is prepared from sodium citrate and sodium pyrophosphate. The agent A, the agent B and the agent C can be prepared respectively and packaged independently, and the agent A is firstly added and uniformly stirred during using; then the agent B is added, and a mixture is stirred uniformly; finally, the agent C is added, the mixture is stirred uniformly, and a weight ratio of the agent A, the agent B and the agent C is 5:5:1. The paint spraying circulating water treatment agent is high in decaking capacity and paint is completely tack-free.

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 and a preparation method thereof. Background technique [0002] When spraying paint in the spray booth, in order to prevent the oversprayed (not applied to the workpiece) paint from scattering, most of the oversprayed paint mist is treated by water curtain or water spin, so that the oversprayed paint floats in the circulating water. But this alone will cause pipeline blockage and overload operation of the circulating pump, which will directly lead to reduced work efficiency or even shutdown. In addition, the cleaning operation of the circulating pool is also extremely difficult and labor-intensive, which brings a lot of inconvenience to continuous production. Therefore, the method of adding chemicals to the painting circulating water is usually used, so that the overspray paint in the circulating wat...

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
