Abstract
The invention relates to a single dosage paint mist coagulant prepared by using a polyethylene wax emulsion as a main component. The single dosage paint mist coagulant is applied in paint mist absorption circulating water of an engineering machinery coating workshop, combines with paint particles in the water and floats up, and effectively solves the problems of poor flocculation, sediment of circulating water, and the like, guarantees to long-term, safe and effective operations of the circulating water. The polyethylene wax emulsion is an ethylene-acrylic acid copolymerized wax emulsion being an EAA type polyethylene wax emulsion. A relatively optimum proportion of reagents is as follows: 20.0% -25.0% of the ethylene - acrylic acid copolymer wax emulsion, 1.0% -2.0% of dicyandiamide, 0.5-1.0% of the surfactant and 72.0%-78.5% of deionized water.
Description
Technical field:
The invention belongs to environmental pollution treatment technology field, be mainly used in Painting Shop wet type except in coating cloud circulating water system.
Background technology:
In automobile, household electrical appliances, furniture, engineering machinery and partly plastic processing industry, painting operation mostly adopts modern spraying technology, in encloses container formula paint spray booth or painting workshop carry out, and be equipped with and send accordingly, exhaust system wet type is except coating cloud system.This wet type except the main purpose of coating cloud system is: remove over-sprayed paint fog, the staff's that sprays paint to keep the scene intact health, prevents that over-sprayed paint fog is to the pollution of to be painted.In painting operation, the normal wet type spray chamber adopting utilizes water as absorption agent, forms spray chamber circulating water.Its principle of work is: coating cloud contacts with cascade or spray water, and paint is eluted to and in water, forms paint particle and taken away by water.Isolating after paint, water continues to recycle.
In order to maintain the operation of recirculated water long-term safety, cross and spray paint and must from recirculated water, separate.This just requires the abundant unsticking of coating cloud quilt to facilitate separation; The inharmonious process of paint is carried out in water, conventionally need in water, add lacquer mist coagulant, make the paint that carries in water fully inharmonious and from water, separate smoothly, to prevent that it from adhering to paint spray booth's wall, pipe pump inwall, draught fan impeller, flume wall etc. and locating to result in blockage.
The comparatively general lacquer mist coagulant of application is all double-formulation at present, and inharmonious dose is used in conjunction with flocculation agent, adds at the different positions of recirculated water, to improve processing and the separation efficiency to coating cloud, is widely used in various Painting Shops, and effect is good.But, in engineering machinery field, owing to existing, application quantity of circulating water is large, anticorrosion class paint filler used is many, mistake is sprayed paint the features such as easy inharmonious difficult flocculation, traditional double-formulation lacquer mist coagulant as: in Engineering Machinery Plant's Painting Shop application process, there is the paint slag floating of can not effectively flocculating in amine aldehyde condensate class, clay class, amphoteric metal salt, polyacrylamide medicament, a large amount of sediments in recirculated water, circulating water quality worsens the problems such as fast.
Summary of the invention:
The present invention is the one-pack type lacquer mist coagulant being mixed with taking a kind of polythene wax emulsion as main component, be applied in engineering machinery class Painting Shop coating cloud absorption cycle water, paint particles in water is combined and is floated, efficiently solve the problems such as flocculation is not good, recirculated water sediment, ensured that recirculated water long-term safety effectively moves.
Product of the present invention is main raw material by a kind of polythene wax emulsion, adds the aqueous solution that Dyhard RU 100 and nonionogenic tenside are mixed with.
Polythene wax emulsion is wherein ethylene-acrylic acid copolymerization wax emulsion, i.e. EAA type polythene wax emulsion.
Preferably proportioning is ethylene-acrylic acid copolymerization wax emulsion 20.0%-25.0%, Dyhard RU 100 1.0%-2.0%, tensio-active agent 0.5%-1.0%, deionized water 72.0%-78.5%.
Tensio-active agent is isooctylphenol polyoxyethylene (10) ether, trade(brand)name OP-10.
The preparation method of this lacquer mist coagulant is that add Dyhard RU 100 in deionized water after, stirring is fully dissolved it, then adds ethylene-acrylic acid copolymerization wax emulsion to stir, and finally adds tensio-active agent to stir.Finally use N, N-dimethylethanolamine regulator solution pH value to 8
Application operating method:
(1) this lacquer mist coagulant should Painting Shop coating cloud absorption cycle water enter spray room ingress slowly add.
(2) addition of this lacquer mist coagulant is the amount of spraying paint 10%～20%
(3) this lacquer mist coagulant is one-pack type lacquer mist coagulant, does not need to add paint flocculation agent in application process.
Embodiment:
Preparation method adds deionized water for stirring to dissolve Dyhard RU 100, then adds ethylene-acrylic acid copolymerization wax emulsion, tensio-active agent to stir, and finally uses N, and N-dimethylethanolamine regulator solution pH value to 8, obtains product.
