Multifunctional separation protective agent for electrostatic paint mist treatment system and preparation method of multifunctional separation protective agent

Abstract

The invention relates to a multifunctional separation protective agent for electrostatic paint mist treatment system and a preparation method of the multifunctional separation protective agent. The multifunctional separation protective agent comprises the components in percentage by mass of 50-60% of a debonding agent, 8-20% of a polyol, 0.2-0.5% of a surfactant and 20-40% of deionized water, wherein the debonding agent is a cationic polyamine; the polyol is glycerol, and the nonionic surfactant is a branched secondary alcohol polyoxyethylene ether. The preparation method is simple to operateand high in production efficiency. The multifunctional separation protective agent is excellent in leveling property and flame retardance, safe and non-corrosive, high in conductivity and capable of effectively covering the surface of a flowing device from top to bottom, so that the paint mist is completely debonded and dispersed, and paint mist is prevented from adhering to the inner wall of thedevice and a pipeline; in the system circulation process, the broken paint mist particles are difficult to float and precipitate, and the suspension state is kept; the absorbed paint mist particles can be removed through a high-speed centrifuge, and the separation agent after the paint mist is removed can be put into the system for cyclic use again, so that cyclic utilization is realized.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to a multifunctional separation and protection agent used in an electrostatic paint mist treatment system and a preparation method thereof. Background technique [0002] The electrostatic paint mist treatment system is similar to the electrostatic oil and gas separator, and the paint mist is adsorbed from the circulating air to the cathode plate under the action of electrostatic force. The cathode plate of the electrostatic paint mist treatment system is covered by the paint mist coagulant, which absorbs and carries away the spray paint mist particles to keep the environment of the spray booth clean. [0003] During the actual use of the traditional paint mist coagulant in the electrostatic paint mist treatment system, paint slag forms into blocks, the bath is not uniform, and the leveling is not good enough to cover the cathode plate. Wear a high-voltage el...

Problems solved by technology

[0005] Disclosed a kind of paint mist coagulant as Chinese patent application CN108726654A, comprises following components: paint mist flocculant, paint flocculant, paint remover, bactericide, defoamer, pH adjusting agent and water; Paint mist flocculant, The dosage ratio of paint flocculant, paint remover, bactericide, defoamer and water is 1.0~2.0:0.5~1.5:0.4~0.8:0.05~0.10:0.2~0.5:1000, and the dosage of pH regulator is the regulation system to pH=7~10; this invention has the effect of treating the paint mist in the spraying room, but when it is applied to the electrostatic paint mist treatment system, it is easy to cause paint slag to form a block, the bath is not uniform, the leveling is not good and the cathode plate cannot be covered, etc.
