Description
Technical field
The outer finish paint paint Slag treatment of technical field of regeneration, particularly a kind of freight container that the present invention relates to discarded paint 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 feet of volume needs the paint of about 15KG, the paint slag that each casing produces is about 2KG, calculate by annual output 100000 TEU freight container, the outer finish paint paint slag of annual generation about 150 tons, 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, proposes the outer finish paint paint Slag treatment of a kind of freight container and makes paint reuse method.
The technical solution adopted for the present invention to solve the technical problems is: the outer finish paint paint Slag treatment of a kind of freight container makes paint reuse method, and the method comprises the steps:
(1) Slag treatment, fragmentation, magnetic separation is painted
Outer finish paint paint slag is collected and dried, with hammer mill (output of 300*400 type 11KW is about 2 tons per hour), paint slag is broken into 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 B60 type can be selected to be 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.
(400 type output are now selected to be about 50 ~ 80KG/h by WFQ type micronizer mill the paint ground-slags of above-mentioned 178 μm (being equivalent to 80 orders), the paint slag solidified, Mohs' hardness is more than 8 grades, general pulverizing mill can only accomplish the average order number of 325 object, maximum 200 orders of all-pass, WFQ can accomplish average 3000 orders, and all-pass reaches more than 500 orders), paint ground-slag is ground to all-pass 400 order and even arrives nano level powder and obtain micropowder filler D;
(3) paint deployment
Above-mentioned micropowder filler D is formed the outer finish paint of freight container through allotment.
The outer finish paint paint Slag treatment of a kind of freight container makes paint reuse method, and the allotment of described outer finish paint has following steps:
(1) in blending vat, add thinner, BR106 acrylic resin successively, add while stirring, be uniformly dispersed with high speed dispersor, general 5-10min;
(2) slowly add chlorinated rubber, with high speed dispersor dispersed with stirring 2-5min, then add toughner clorafin, dispersed with stirring 5-10min;
(3) use vacuum feeder, slowly in blending vat, add micropowder filler D, stir while adding, after adding, start high speed dispersor high-speed stirring and disperse 9-15min; At this moment most of micropowder filler D can be dissolved in organic solvent.Add lower molecular weight wetting and dispersing abrasive, carry out sand mill and be ground to fineness and reach in 30 μm, deployed is like this outer top-coat resin composition;
(4) the outer finish paint of freight container is namely obtained through 200 order filtering nets after being ground by above-mentioned composition;
Each components in mass portion number meter in described composition, has following formula: thinner 18-22, BR106 acrylic resin 8-15, chlorinated rubber 4-6, clorafin 4-6, micropowder filler D50-70, abrasive 0.2-0.8; Wherein, 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.
Further, each components in mass portion number meter in described composition, has following formula: thinner 20, BR106 acrylic resin 10, chlorinated rubber 5, clorafin 5, micropowder filler D60, abrasive 0.5; Wherein, dimethylbenzene and the propyl carbinol of thinner to be mass ratio be 7:3.
Further preferably, in described thinner, dimethylbenzene and propyl carbinol mass ratio are 7:3.
In micropowder filler D containing the mica powder of 10%, the titanium dioxide of 25% and 20% chlorinated rubber and vinylformic acid be processed into super-fine powder, add filler D and through grinding after, chlorinated rubber and vinylformic acid also can be dissolved in solvent or diluent, remaining mica powder and titanium dioxide just as be paint in filler.
The grinding of above-mentioned composition adopts horizontal sand mill, is disperseed by the ultra micro paint ground-slag in resin combination, needs through shredder twice grinding that (grinding medium is φ 1.6-1.8mm cerium stabilised zirconia pearl-80 zirconium, and hardness is high, wear-resisting; Rotating speed: 0-1440rpm).Namely the spraying of the outer finish paint of freight container is can be used for through 200 order filtering nets.Because micropowder filler D color is more assorted, when this outer finish paint uses, first mix existing outer finish paint on half production line, make this color of paint and the outer finish paint color similarity of on-the-spot certified products; Usage is: the precoating for the outside upper bottom side rail of case is sprayed and the place of all pre-spray positions in advance.
Technical scheme of the present invention is that solid hazardous waste is sprayed the method using freight container and get on after pretreatment 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 4%, remarkable in economical benefits, is suitable for applying at Production Container industry further genralrlization.
