Abstract
The invention discloses efficient plastic doffing agent and belongs to the chemical plastic (paint) doffing technical field. Dichloromethane, chloroform or the solution of the two that is mixed according to any weight ratio is used as solvent. And the agent is made from the solvent which is added with formic acid to be uniformly mixed. The weight ratio of the raw materials is 5 to 10 percent of formic acid, 0 to 95 percent of dichloromethane and 0 to 95 percent of chloroform. The active effects of the invention are that the raw materials are simple and the preparation is convenient and rapid. And the invention is suitable for the field preparation and the using of coating manufacturers. The agents has the advantages of no-chemical damage to work pieces, wide application range, simple post treatment and easy operation, which is beneficial to recoating.
Description
Technical field
The present invention relates to remove a kind of highly effective plastic coating remover of powder coating coating or paint coating, belong to chemistry and take off and mould (lacquer) technical field.
Background technology
The various depainting products that remove paint coating are a lot, efficiently solve the japanning product the older coating in the processing remove problem, as Chinese patent CN1113926A, CN1492007A, 1743389A, 1944547A etc., paint film removed all have effect preferably.Powder coating and application processing industry development at present is swift and violent, and China has become first producing country of world's powder coating and application processing country, and each powder coating producer all constantly runs into the application problem again that removes of old powder coating (being commonly called as the plastic-blasting layer).Because most paint remover is difficult to remove effectively fast the plastic-blasting layer on the market, the general now method that adopts has that naked light calcination, strong acid (alkali) high temperature boil, mechanical grinding.
Chinese patent CN1611556 has introduced a kind of strong acid high temperature and has taken off the method, the CN101008174A that mould and introduced the removal methods that the chemistry of Shot Blasting combines with physics behind a kind of first high temperature ageing, these take off molding process and have certain cleaning effect, but limitation is all arranged.The former boils bubble by strong acid, and intensive oxidation and corrosive nature are arranged, and workpiece and aftertreatment are had strict requirement; Suitable large-scale, the simple in structure and resistant to elevated temperatures member of the latter is handled, and they are all not too suitable concerning most of plastic-blasting workpieces.
Summary of the invention
The object of the present invention is to provide preparation simple, easy to use, take off mould quick, safe and efficient, take off aftertreatment and be easy to a kind of highly effective plastic coating remover.
For addressing the above problem, technical scheme of the present invention is: made solvent, formic acid added to mix in the solvent make than mixing solutions by any quality by methylene dichloride, trichloromethane or the two, the weight percent of each raw material is:
Formic acid 5-10%
Methylene dichloride 0-95%
Trichloromethane 0-95%.
Use separately methylene dichloride or trichloromethane as solvent or use the two press any quality than mixing solutions as solvent, all have good result of use.
Product of the present invention is brushed old coatingsurface with instruments such as hairbrush with it in use, can all remove in general powder coating 0.5-2 minute; Also can take off to soak in the workpiece immersion plastic coating remover of moulding and all to remove in 0.5-2 minute.General coat of painting 5-30s can remove.(as 100 μ m or 200 μ m) the proper extension solution impregnation time got final product when coating was thicker.
Positively effect of the present invention is: raw material is simple, and preparation is well suited for on-the-spot preparation of application producer and use easily and fast.Each reagent does not have the chemistry injury to workpiece, applied range, and also aftertreatment is simple, carries out easily, helps the carrying out of application again.
Embodiment
Enumerate 4 embodiment altogether.Each Example formulations and result of use see Table 1.
The preparation method is: elder generation by prescription sampling preparation, adds formic acid with solvent then, mixes to get final product.
Using method is: take off when moulding instruments such as using hairbrush it is brushed old coatingsurface, flood and got final product in 0.5-2 minute; Or workpiece directly immersed in the plastic coating remover to soak removed in 0.5-2 minute; During overweight coating, can flood or soak time by proper extension, remove until the coating swelling.
