Multifunctional separation and protection agent for electrostatic paint mist treatment system and preparation method thereof

Abstract

The invention relates to a multifunctional separation and protection agent used in an electrostatic paint mist treatment system and a preparation method thereof. The multifunctional separation and protection agent includes the following components and mass percentages: debonding agent 50-60%, polyol 8-20% %, 0.2-0.5% surfactant, 20-40% deionized water, wherein, the debonding agent is cationic polyamine, the polyol is glycerol, and the nonionic surfactant is branched Secondary alcohol polyoxyethylene ether; the preparation method is simple to operate and high in production efficiency; the invention has excellent leveling properties, flame retardancy, safety and non-corrosion, good electrical conductivity and effectively covers the surface of the equipment flowing through it from top to bottom , so that the paint mist can be completely debonded and dispersed to prevent the paint mist from adhering to the inner wall of the equipment and pipes. During the process of system circulation, the broken paint mist particles are not easy to float and settle, and remain in a suspended state; the absorbed paint mist particles can be passed through high-speed centrifugation After removing the paint mist, the separating agent can be put into the system again for recycling to realize recycling.

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 adjustment 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.
