Abstract
The invention provides an economic environment-friendly degradable paint mist flocculating agent. An employed raw material is cation modified starch (with the substitution degree of 1.0-2.5), and base starch of the modified starch is natural starch, therefore the raw material is easily available and low in cost, and also is biodegradable and free of secondary pollution to environment. The paint mist flocculating agent can enable different-resin-type paint to lose viscosity, and has relatively good broad-spectrum property. The invention also provides a preparation method of the paint mist flocculating agent. The paint mist flocculating agent is applicable to circulating water processing in a wet-type paint mist removing system.
Description
Technical field:
The present invention relates to preparation and the application thereof of a kind of economy, environment-friendly degradable paint mist polycoagulant, particularly relate to and a kind ofly can make mistake in the paint line recirculated water efficient inharmonious lacquer mist coagulant and preparation method thereof that sprays paint.The feature that product of the present invention has is that economy, environmental protection, production technique are simple.Belong to technology for treating industrial waste water field.
Background technology:
In the time of Painting Shop operation, conventionally there is greatly paint not to be coated with to install on workpiece and became and spray paint, accumulate over a long period, these mistakes of gluing are sprayed paint and can be gathered on wall, top board and the bottom of spraying area, at the bottom of can adhering to equipment surface, heaping groove, stop up circulating line, nozzle etc., if things go on like this, not only severe contamination ambient air and environment, also can affect the treatment effect of equipment, increase the maintenance cost of equipment.For improving the utilization ratio of painting operation environment, raising recirculated water, should specifically process the paint of crossing spraying, at present, two kinds of conventional methods are mechanical curettage method and lacquer mist coagulant method.And for the tough paint of paint, lacquer mist coagulant method has been showed larger advantage.So-called lacquer mist coagulant method refers in water circulation system and adds a kind of medicament, can, by the viscous fracture of paint particle, paint inharmonious effect thereby reach.
At present, conventional lacquer mist coagulant mainly comprises: carbamide class, inorganic, organic polymer class, wilkinite, tannin, chitosan.Carbamide polymer production cost is low, technique simple, recirculated water is crossed to the inharmonious effective of discharge rate paint, be therefore widely used as a kind of coating cloud agglutinant, but because the shortcoming of this series products is to contain excessive free formaldehyde.Because formaldehyde is a kind of potential carcinogenic substance, the health of serious harm human body, current many countries have started to ban use of gradually; Inorganic, organic polymer class water conditioner, although water treatment is had to certain treatment effect, itself does not have biodegradable, can increase the content of COD in water body, BOD etc., and water body is caused to serious secondary pollution; The lacquer mist coagulant becoming taking wilkinite as Raw material processing, although have certain biodegradability, raw material is mainly by external import, and price is higher, thereby has increased the cost of processing waste water, economical not.
U.S. Patent number US2010/0326923A1, it has described a kind of high performance environments affects few inharmonious dose, in this patent, use a kind of biodegradable raw material, this raw material is the cationic starch of substitution value between 0.01～1.0, the making processes of its patented product is by certain density cationic starch furnishing liquid, and must add a kind of acid to dilute, regulate the pH of starch solution between 5.5～6.0, add again afterwards some metal-salts etc.Starch, is a kind of polysaccharide carbohydrate, is mainly derived from some green plantss, is renewable resources in.
The object of the invention is to overcome the shortcoming of above-mentioned prior art, its principal feature having is:
1, the raw material that the present invention adopts is a kind of cationic modified starch, and the base starch of this starch is native starch, has biodegradability, can not cause secondary pollution to environment.
2, the cationic modified starch that the present invention adopts need contain enough cationic charges, and substitution value scope is 1.0～2.5.
The base starch of day ion modification starch 3, using in the present invention is drawn materials easily, price economy, thereby has reduced production cost.
4, production technique of the present invention is simple, energy consumption is little.
5, it is inharmonious that the present invention can make solvent-based paint and the water-based paints of different resins type, has good broad spectrum.
Summary of the invention:
The object of this invention is to provide a kind ofly has economic environment-friendly degradable paint mist polycoagulant well inharmonious, cohesion to solvent borne, water-miscible paint.
The present invention also aims to provide the preparation method of this lacquer mist coagulant.
The present invention also aims to provide the application method of this lacquer mist coagulant in Painting Shop recirculated water.
Lacquer mist coagulant of the present invention is that main raw material forms by cationic modified starch, metal-salt, the polymkeric substance of biodegradable.
Cationic modified starch in the present invention, the scope of its substitution value is between 1.0～2.5.
Cationic modified starch in the present invention, its base starch can be derived from but be not limited to wheat, corn, potato, rice, sweet potato, cassava and mung bean etc.
Metal-salt in the present invention can be but be not limited to aluminium, zinc, iron, calcium, magnesium etc.
Polymkeric substance in the present invention can be but be not limited to polymerize aluminum chloride, polymerization aluminum nitrate and polyacrylamide etc.
The economic environment-friendly degradable paint mist polycoagulant of one of the present invention is a kind of colourless or light yellow translucent thick liquid.
The present invention can be used as one-pack type lacquer mist coagulant and uses, and also can coordinate some flocculation agents to use.
The preparation method of a kind of economic environment-friendly degradable paint mist polycoagulant of the present invention comprises following processing step:
In there-necked flask, add tap water: 86.0～97.0 parts, be placed in thermostat water bath and stir;

Use properties of the present invention can be verified with jar jolting:
The paint waste water that first adds 200ml to get from circulating water system in the jar of 250ml, uses pH adjusting agent that the pH value of water is adjusted between 7～9.
Add subsequently the circulating water treatment agent 0.5～1.5g preparing, cover bottle cap, in 30 seconds of fierce jolting, leave standstill observing effect.
Can be found out by experiment, in all embodiment, the better cost of manufacture of pharmacy effect that embodiment 8 embodies is lower, can be used as preferential selection.
Simultaneously can be by usual method for paint spray booth, the basic consumption of medicament can be controlled in 1～3 ‰, and preferably 2 ‰.Adding of agent place can be the ingress of mixing tank or water circulating pump, so that medicament mixes, the additional amount of medicament can according to the amount of spraying paint number do suitable supplementing, it is good that the handing in retroactively of medicament adds the ingress that is in recycle pump, spray paint with the mistake in guarantee water cycle completely inharmonious, reach the effect of condensing, flocculating.
