Abstract
The invention relates to the technical field of waste paint regeneration, especially to a method for treatment of container primer paint slag to make paint for reuse. The method includes the steps of: paint slag treatment, crushing, magnetic separation, grinding of paint slag into powder, and paint blending. The technical scheme involved in the invention solves the problem that the solid waste of the container manufacturing industry cannot be treated in the prior art, and reduces the paint treatment cost. Container manufacturing enterprises no longer need to bear heavy treatment cost, environmental protection burden and social environment risk in terms of paint slag treatment. The paint production cost is lowered, and the paint material cost of container manufacturing enterprises is reduced by 8%. With significant economic benefits, the method is suitable for further popularization and application in the container manufacturing industry.
Description
Technical field
The present invention relates to the technical field of regeneration of discarded paint, particularly a kind of freight container priming paint paint Slag treatment makes paint reuse method.
Background technology
Freight container has some strength, rigidity and specification, specializes in the large-scale goods container that turnover uses, and uses container transshipment goods, can directly freight in the warehouse of shipper, transport to the warehouse unloading of Consignee, more change trains in midway, ship time, goods need not be taken out in case and change the outfit.In Production Container process, the casing of each 20 volume needs the dust primer of about 26KG, and the paint slag that each casing produces is about 4KG, calculate by annual output 100000 TEU freight container, annual generation about 400 tons paint slag, a large amount of waste paint slags, will bring white elephant to society and container factory.In those early years, the treating method of paint slag is that deep fill buries or is poured in river substantially, in recent years, solid hazardous waste deposit and to dispose requirement more and more higher, need factory please have the professional treatment company process solid waste hazardous material of process qualification, processing cost is higher.In view of more than, the treatment process of research and development freight container waste paint slag, the process of freight container solid waste is clean, and can produce certain economic worth is the technical problem that those skilled in the art will solve simultaneously.
Summary of the invention
Technical problem to be solved by this invention is: paint the higher problem of Slag treatment cost for the freight container application existed in prior art with discarded, propose a kind of freight container priming paint paint Slag treatment and make paint reuse method.
The technical solution adopted for the present invention to solve the technical problems is: a kind of freight container priming paint paint Slag treatment makes paint reuse method, and the method comprises the steps:
(1) Slag treatment, fragmentation, magnetic separation is painted
Priming paint paint slag is dried, uses hammer mill (output of 300*400 type 11KW is about 2 tons per hour) that paint slag is broken into the comminutions within 10mm; By screen cloth, by the granule sieving of below 3mm out, what be greater than more than 3mm carries out fragmentation again, until be substantially all crushed to the size of below 3mm; With Y-019 magnetic separator, the iron ash steel sand in the discarded paint slag of below 3mm is separated, after first time de-iron, once paint the de-iron of slag again, guarantee that most steel sand is rejected clean;
(2) sizing powder is painted
Use Universalpulverizer (production capacity of optional B60 type is about 500KG/h) equipment by the paint sizing powder of above-mentioned below 3mm, by the paint ground-slag of paint sizing to the size (being equivalent to 80-200 order) of less than 178 μm; The filtering net cracky of above-mentioned Universalpulverizer (B60 type) equipment is below solution:
Need outside the filtering net of B60 type Universalpulverizer to reequip the outer ring (hole of the countless diameter 10mm of outer girth sheets upper punch) that a set of thickness is 2.0mm, width is 200mm, diameter is 600mm, 80 object filtering nets (thickness 0.8mm, width 200mm, diameter are 600mm) are contained in inside the thick punching iron web plate of 2mm as inner ring web plate, guarantee that 80 object filtering nets are close to thick outer ring punched-plate, be not so just broken; When using B60 type Universalpulverizer to pulverize this paint slag, often pulverizing 100KG need open crushiing chamber, is removed by iron sand residual on 80 object filtering nets totally and continues to pulverize again.
By the paint ground-slags of above-mentioned 178 μm (being equivalent to 80 orders) by WFQ type micronizer mill (now selecting 400 type output to be about 50 ~ 80KG/h), even arrive nano level powder by little for paint ground-slag mill to 500 ~ 3000 orders; The sizing of above-mentioned priming paint paint becomes micropowder filler A;
(3) paint deployment
Allocated by above-mentioned micropowder filler A and form paint, the order number scope of micropowder filler A is 500-3000 order; The allotment of paint has following steps:
A. in blending vat, add thinner successively, admittedly admittedly contain E44 resin containing E20 resin, 100% containing 75% of toughner, add while stirring, be uniformly dispersed with high speed dispersor;
B. slowly add 801 organobentonites (200 order), with high speed dispersor dispersed with stirring 2-5min, 801 organobentonites are all dissolved in resin and go;
C. use vacuum feeder, slowly in blending vat, add micropowder filler, stir while adding, after adding, start high speed dispersor high-speed stirring and disperse 9-15min; Add lower molecular weight wetting and dispersing abrasive, the paint resin combination stirring while adding deployed.
D. through 200 order filtering nets after above-mentioned composition being ground, mix solidifying agent must paint, the grinding of mixture adopts horizontal sand mill, ultra micro paint ground-slag in resin combination is disperseed, only need through shredder once, grinding medium is φ 1.6-1.8mm cerium stabilised zirconia pearl-80 zirconium, and hardness is high, wear-resisting; Rotating speed: 0-1440rpm, according to the allotment of different micropowder fillers, the priming paint containing micropowder filler A is used for the spraying of freight container sanding priming paint and paint line priming paint.
In above-mentioned steps, each components in mass portion number meter, has following formula: thinner 12-16, admittedly contains E20 resin 6-10 containing 75% of toughner, and 100% admittedly containing E44 resin 3.5-6.5,801 organobentonite 0.5-1.5, micropowder filler 60-80, abrasive 0.2-0.8; Wherein, solidifying agent is low relative molecular mass No. 650 polymeric amide (solid content of 60%), the mass ratio of resin combination and solidifying agent is (95-120): (7-9), and thinner is mass ratio is (5-8): the dimethylbenzene of (2-4) and propyl carbinol; Abrasive is the electric neutrality salt of organic acid and organic amine, here be Linan, Zhejiang Fu Sheng coatings additive(s) company limited produce wetting dispersing agent 108 type product; Admittedly containing E20 resin containing 75% of toughner is dibutyl phthalate DBP.
In above-mentioned steps, the preferred mass ratio of each component is: thinner 15.5, admittedly admittedly contains E44 resin 5,801 organobentonite 1 containing E20 resin 8,100%, micropowder filler 70, abrasive 0.5 containing 75% of toughner; Wherein, dimethylbenzene and the propyl carbinol of thinner to be mass ratio be 7:3.
Containing the zinc powder of 70% and talcum powder in micropowder filler A after micronizing machining, in this filler, 75% is pigment extender part, spray to body surface after in redispersion to resin, fine and close protective layer can be formed, play physics and hide and protection rot-resistant effect;
Technical scheme of the present invention is that solid hazardous waste is sprayed the method using freight container and get on after treatment again, has following beneficial effect:
(1) problem that the solid waste solving Production Container industry in prior art cannot process;
(2) reduce paint processing cost, the paint Slag treatment of container production enterprise need not bear heavy processing cost, environmental burden and social environment risk again;
(3) reduce paint production cost, the material of paint cost of container production enterprise reduces 8%, remarkable in economical benefits, is suitable for applying at Production Container industry further genralrlization.
