Description

Lacquer mist coagulant and preparation and application that a kind of treatment solution with waste oil residue is a main component

Technical field:

Raw material that the present invention adopts is a main raw material with the treatment solution of waste oil residue, after necessary the processing, with the water purification composition through a series of reaction, make have efficient dispersion, throwing out, that do not produce secondary pollution, be used for the special-purpose water treatment agent that high-concentration waste water is handled.Belong to the environmental pollution treatment technology field, relate to the lacquer mist coagulant in a kind of wet type spray chamber, the paint line circulating water treatment, the invention still further relates to the preparation method and the application of this lacquer mist coagulant simultaneously, reduced the cost of raw material on the one hand, reach the purpose of resource recycling on the other hand, promoted the development of recycling economy.

Background technology:

In automobile, household electrical appliances, furniture industry 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 give accordingly, the exhaust system wet type removes the coating cloud system.The main purpose that this wet type is removed the coating cloud system is: remove over-sprayed paint fog, the staff's that sprays paint to keep the scene intact health prevents that coating cloud is to be painted pollution.The normal wet type spray chamber that adopts utilizes water as absorption agent in painting operation, constitutes spray chamber circulating water.Its principle of work is: coating cloud contacts with cascade or spray water, and paint is eluted in the water and forms paint particle and taken away by water.After adopting special process to isolate paint, water continues to recycle.

U.S. Patent number 5250189 " utilizes aluminium salt to remove the method for coating removal particle from the water-miscible paint system ", be main raw material mainly among the present invention with aluminium salt, similarly inorganic salts as: zinc salt, silicate etc., also having with clay, tannin, melamine formaldehyde (MF) etc. is the lacquer mist coagulant of main raw material.It is the research and development theory of breach with inorganic salt, organic polymer that the present invention has changed traditional, but is main raw material with the waste residue treatment solution, and its outstanding feature is:

1, the waste residue to produce in the glycerine processing.

2, the lacquer mist coagulant of making through series of processes that does not produce secondary pollution with efficient dispersion, throwing out.

3, reduce the cost of raw material.

4, reached the purpose of resource recycling.

5, promote the development of recycling economy.

This lacquer mist coagulant absorption parcel coating cloud, coating cloud is converted to inadhesive cellular, thereby make the mistake in the recirculated water spray paint inharmonious, 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, make the paint that carries in the water fully inharmonious and from water, separate smoothly, inharmonious paint generally swims on the water surface, be suspended in the water or under be sunken in the water.

Summary of the invention:

The purpose of this invention is to provide a kind ofly has lacquer mist coagulant well inharmonious, cohesion to solvent based coating and water-borne coatings.

Another object of the present invention is that the extracting solution with waste oil residue is a main raw material, reaches the purpose that resource is recycled.

The invention provides the preparation method and the application of this lacquer mist coagulant.

Lacquer mist coagulant of the present invention is made up of a kind of treatment solution, tensio-active agent, dispersion agent and thinner of waste oil residue.

Lacquer mist coagulant of the present invention is a kind of stable in properties aqueous dispersions russet, is used for the processing that wet type is removed coating cloud systemic circulation water.

The extracting solution 10%～20% that contains waste oil residue in the aqueous dispersions; Tensio-active agent (molecular weight is 200～1000) 0.5%～2%; Dispersion agent 0.5%～3%; Water (thinner) 89%～75%.

The extracting solution of waste oil residue is mainly to produce waste oil residue gained after a series of processing treatment of glycerine.

Tensio-active agent can be an anionic, as Sodium dodecylbenzene sulfonate, secondary alcohol Soxylat A 25-7 sulphosuccinates, fatty alcohol sulfate salt.Nonionogenic tenside is as alkylphenol polyoxyethylene, polyoxyethylene alkyl amine.The positively charged ion or the zwitterionics that in addition also can add other.

Dispersion agent can be pyrophosphate salt, polyphosphoric acid salt or organophosphate.

The preparation method of lacquer mist coagulant comprises following processing step:

1. be in 100 ℃ water-baths to heat with 1: 1 ratio in temperature with waste oil residue and water, and constantly stir and treat that waste oil residue dissolves fully, stop heating, regulate pH value 3～5 with the vitriol oil, there is throw out to occur, the elimination precipitation is regulated PH=3 with dilute sulphuric acid, adds Repone K to the saturated component I (waste oil residue extracting solution) that gets;

2. with 10～20 parts of I, add stirring and dissolving in 50 parts of water

3. the tensio-active agent stirring and dissolving that adds 0.5～2 part then.

4. add 0.5～3 part dispersion agent again, and add the aqueous dispersions that 39～25 parts water high-speed stirring was made stable in properties in 2～4 hours.

Lacquer mist coagulant of the present invention in use can be used with organic polymer coargulator, can help inharmoniously to take off steady coating cloud and flocculate rapidly, separates from water.

Use properties of the present invention can be verified with the jar jolting:

The tap water that adds 100ml earlier in the jar of 200ml adds the lacquer mist coagulant 0.5～1g for preparing afterwards, covers bottle cap, shakes bottle a bottle interior material is mixed.

Subsequently, add the paint (water base or solvent base) of 3～10g in bottle, in 30 seconds of fierce jolting, leave standstill observing effect: paint viscosity is porous block and floats on the water surface by completely destroy; Walls of beaker does not have tangible bur, and water quality is limpid.

Simultaneously can be used for paint spray booth by usual method, the basic consumption that adds lacquer mist coagulant can be controlled in 1 ‰～3 ‰, preferred 2 ‰.The additional amount of medicament can be according to suitable the replenishing of how much doing of the amount of spraying paint, and it is inharmonious fully to spray paint with the mistake in the assurance water cycle, reaches the effect of condensing, flocculating.

The present invention compared with prior art has the following advantages:

1, the present invention prepares that the raw materials cost of lacquer mist coagulant is low, technology is simple.

2, the used main raw material of the present invention reaches the purpose of resource recycling based on the extracting solution of the waste residue that produces in the edible oil processing, does not produce secondary pollution simultaneously.

3, lacquer mist coagulant of the present invention is applied in wet type except that in the processing of coating cloud systemic circulation water, and handling procedure is simple, and is convenient, makes over-sprayed paint fog unsticking cohesion quickly and efficiently, flocculation in the water, separates from water with the form of lacquer slag.
