Abstract
The invention discloses a method for treating oil paint residues and belongs to the technical field of waste treatment. The method includes the steps that firstly, the water-contained oil paint residues to be treated are sucked and filtered, and moisture is removed; secondly, dodecylbenzene sulfonic acid and liquid paraffin are added, in the gradual temperature rising process, full modifying, dispersing and homogenizing are conducted, generated mixed steam is condensed and separated, and raw oil paint is prepared. When the raw oil paint is used for preparing oil paint, the quality of the obtained oil paint is good.
Description
Technical field
The invention belongs to waste treatment technique field, relate in particular to a kind for the treatment of process of paint slag.
Background technology
In paint spraying operation process, its spraying utilization ratio is only generally 20%～60%, and the coating cloud ejecting has in half room wall, pipeline and tank that flies to paint spray booth, has produced thus a large amount of paint slags.
At present, the domestic processing to paint slag mainly contains 3 kinds: landfill method, combustion method and reclaiming utilize method.Wherein, though landfill method is the simplest treatment process, it has not only taken a large amount of land areas, serious waste land resources, but also easily cause environmental pollution, destroy underground water etc.; Although combustion method can make paint slag obtain processing, it produces a large amount of environmentally harmful gas in combustion processes, thereby has caused secondary pollution; And utilize method about reclaiming, because existing reclaiming technology is too simple, coarse, the quality of the product that its reclaiming obtains is undesirable, is difficult to realize industrial applications.
Summary of the invention
The technical problem that the present invention solves is to provide a kind for the treatment of process of paint slag, and this treatment process is paint slag to be carried out to reclaiming make paint raw materials, and its paint raw materials that make are superior in quality.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A treatment process for paint slag, these renovation process following steps:
A. pending aqueous paint waste residue is put into agitator, stir, and then deliver in filter cloth machine and be distributed in uniformly on filter cloth, carry out suction filtration, collect filter cake; Wherein, the aperture of described filter cloth is 0.070 millimeter～0.075 millimeter, and the pumping speed of described suction filtration is 10m
3/ h～12m
3/ h;
After B.A step, under agitation condition, by filter cake described in 80 weight part～90 weight parts, 5 weight part～8 weight part Witco 1298 Soft Acids and 8 weight part～12 weight part whiterusss are put into reactor, first at 65 ℃～75 ℃, stir 15 minutes～20 minutes, then be warming up to 100 ℃～120 ℃ and stir 15 minutes～20 minutes, be then warming up to again 180 ℃～220 ℃ and stir 30 minutes～40 minutes;
C. the mixing steam whole process of B step being produced enters water-and-oil separator after condenser is collected, and obtains the material of solid state, makes paint raw materials.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The present invention, by first pending aqueous paint waste residue being carried out to suction filtration, removes moisture, then adds Witco 1298 Soft Acid and whiteruss, in temperature-rise period progressively, carry out sufficient modification and homogeneous dispersion, mixing steam condensation, separation by producing, make paint raw materials; When these paint raw materials are made in to preparation paint, the paint quality obtaining is good.
