Abstract
The invention relates to a paint spray mist coagulant which shows a good effect on viscous dissipation and coagulation for a solvent-based coating and a water soluble coating. The paint spray mist coagulant is especially applicable to circulating water treatment of a wet type paint spray mist removal system. The paint spray mist coagulant comprises an agent A, an agent B and an agent C, wherein the agent A is a linear high-molecular polymer which has high electric neutrality and can quickly neutralize the paint particle charge and warp the paint particles to realize viscous dissipation; the agent B is an aqueous solution prepared through etherified modified potato starch waste residues with molecular weight of 50,000 to 60,000, which enables the viscosity-free paint particles to be collected; the agent C is used for regulating the pH (Power of Hydrogen) of the circulating water. The invention also provides a preparation method and application of the paint spray mist coagulant. The paint spray mist coagulant is simple in preparation method and convenient in application; the potato starch waste residues are utilized as the raw materials of the agent B, so that the secondary utilization of wastes is realized, and the effect of treatment of wastes with processes of wastes against one another is reached; in addition, the paint spray mist coagulant has the biodegradability so that secondary pollution caused by the application in water can be avoided, and the environmental load can also be reduced effectively.
Description
Technical field
The invention belongs to environmental pollution treatment technology field, relate to a kind of lacquer mist coagulant being applied in wet type paint spray booth circular water treating system.The invention still further relates to preparation method and the application of lacquer mist coagulant simultaneously.
Background technology
This product is mainly used in spraying paint in treating processes of the industries such as household electrical appliances, electronic product, engineering machinery, auto parts, motorcycle, and because nearly 20 ~ 60% paint in painting process is not attached on device, this part paint was called spray paint.These paint contain the volatile organic solvent that damages in a large number HUMAN HEALTH, need to clear up in time, if paint is fallen to the ground and is difficult to cleaning, so paint industry adopts wet type spray chamber circulating water system to catch spray paint conventionally.Organic solvent is because the water cycle of indoor water tank and outdoor tank flows and taken out of outdoor, the healthy effect of reduction to operator, and cross spray paint, because viscosity is large, can stick on tank, pipeline and water pump wall, thereby can affect water purification system normally moves, can affect coating quality simultaneously, reduce recirculating water purification efficiency, increase the replacing number of times of recirculated water.In order to maintain paint spray booth's long-term safety normal operation, cross spray paint and must from recirculated water, separate.Conventionally need in recirculated water, add lacquer mist coagulant, coating cloud be disappeared sticky, be condensed into vesicular caking, swim in the water surface, and regularly salvage, so not only extended the work-ing life of equipment, and improved the Working environment of paint spray booth, and allow water circulation use, saved resource.
In addition, in lacquer mist coagulant in the market, take polyacrylamide as main, polyacrylamide (PAM) Zeng Yinqi has powerful net to catch, build bridge function and often combines use with polymerize aluminum chloride (PAC), obtain good flocculation turbidity removal effect, and be applied to the processing links of tap water.But also have in the recent period experiment to show, although polyacrylamide safety non-toxic, the acrylamide monomer of its decomposition is the agent of a kind of nervosa intoxicating, and neural system is had damage, and shows human body after poisoning unable, the symptoms such as ataxia.During the hygienic standard of a lot of countries polyacrylamide in working out drink ArsenazoⅢ, monomer content wherein is all given to suitable restriction.Therefore,, in order to prevent the secondary pollution to environment, prepare efficiency natural, lacquer mist coagulant nontoxic, easy degraded is extremely important.The present invention be take yam starch waste residue as the product that raw material obtains, and has reduced the secondary pollution to water body when utilizing, and has effectively protected environment.
Summary of the invention
The object of this invention is to provide a kind ofly has to solvent-home and water-iome paint the lacquer mist coagulant sticky, cohesion that well disappears.
Another object of the present invention is to provide the preparation method and application of this lacquer mist coagulant.
The A agent of lacquer mist coagulant of the present invention is a kind of linear polymeric polymkeric substance, there is very strong charge neutrality, in can be promptly and paint particles electric charge, parcel paint particles makes it lose viscosity, the aqueous solution that B agent is prepared at 5 ~ 60,000 etherification modified yam starch waste residue by a kind of molecular weight, the paint particles that loses viscosity can be gathered together, C agent is used for regulating recirculated water pH.
The preparation method of described A agent solution is by trimeric cyanamide and formaldehyde, in amount of substance than for 1:(1 ~ 2) ratio be added to the water successively, with hydrochloric acid, adjust pH to 2 ~ 4, at 60 ~ 80 ℃, react 2 ~ 4 hours, make A agent solution.
The preparation method of described B agent solution is added to the water molecular weight at 5 ~ 60,000 etherification modified yam starch waste residue, make the concentration of solution reach 10 ~ 20% grams per milliliters, then under normal temperature, stirs 1 hour, makes B agent solution.
The preparation method of described C agent solution is added to the water sodium hydroxide, makes the concentration of solution reach 10% ~ 30% grams per milliliter, then under normal temperature, stirs it is dissolved completely, makes C agent solution.
The application of lacquer mist coagulant of the present invention, get a water white Plastic Bottle, add containing paint waste water, first with C agent, will be adjusted to 8 ~ 10 containing paint waste water pH value, then containing in paint waste water, adding A agent, build bottle cap, firmly fluctuate, until A agent with containing paint waste water, fully mix disappear sticky after, then add B agent in waste water, build bottle cap, firmly fluctuate 1 ~ 2 minute, standing, paint particles condenses, floats, lumps, floats on the water surface again, on bottle wall, there is no obvious bur, lower floor's water quality is limpid.
The present invention compares with at present conventional lacquer mist coagulant, has following advantage and beneficial effect.
Advantage: the raw material sources of lacquer mist coagulant prepared by the present invention extensively, prepare simple, easy to use, consumption is few, makes sprayed paint fog in water disappear fast and effectively sticky, cohesion, flocculation, with the form of Oil Paint Slag, from water, separates, and water cycle is used.
Beneficial effect: 1. the B agent in lacquer mist coagulant of the present invention, adopt modified potato starch waste residue, played the second stage employ of refuse, reach the effect of " treatment of wastes with processes of wastes against one another ", improved value-added content of product.
2. lacquer mist coagulant of the present invention belongs to complete heavy metal free formula, and the waste water discharging can not cause any heavy metal contamination.
3. lacquer mist coagulant of the present invention can effectively improve paint spray booth operating environment, improve recirculating water purification running efficiency of system, better improve cycle water, and reduce recirculated water, change number of times, degradable yam starch waste residue is contained in the Oil Paint Slag the inside producing, these contribute to the degraded of Oil Paint Slag, eliminate the secondary pollution of supernatant to environment.
