Abstract
The present invention provides a kind of method removed to the coating for being attached to application fixture comprising the process for making water paint remover combination be contacted with fixture with the application for being attached with coating, above-mentioned application are the fixtures implemented transpassivation and handled with fixture.
Description
Technical field
The present invention relates to the application works that can remove effectively the various coated objects headed by the coating process by automobile
The coating stripping means of accompanying on application fixture used in sequence, accumulation solidification or uncured coating or film.
Background technology
Application fixture is used in the various coating process headed by the coating process by automobile, still, if coating attachment,
These application fixtures are piled up in, then workability or function can reduce, it is therefore desirable to be shelled at regular intervals from application with fixture
From removing solidification or uncured coating.
As the application fixture used in the coating process for applying the coated object headed by being filled with automobile, example can be enumerated
Such as mask clamp, bamboo curtain splint and paint booth.As the method for removing accompanying film on these application fixtures, always with
Come, it is proposed that various methods：(i) use makees coating remover as main component with organic solvents such as dichloromethane, diluents
Method；(ii) by the method to be used after caustic alkali waterborne cleaning agent heating as main component；(iii) it is burned
The method of processing；And the method that (iv) assigns physical vibration or impact using hammer, scraper plate etc.；(v) coating will be prevented attached
The method that the silicone resin or fluororesin are applied.
It is applied however, method (i) is used as due to the use of the chlorine series solvent such as the incendivities such as dimethylbenzene, ketone solvent or dichloromethane
Expect remover, it is therefore desirable to which countermeasure of igniting is saved and prevented to operating environment from damage.This method is in toxicity, foul smell, inflammability and waste liquid
Processing etc. occupational healths, environmental pollution aspect there are many problems.Especially shelled with dichloromethane coating as main component
It is noted and is applied flexibly extensively used as the prior art from agent, it can be difficult to using in the morbidity for worrying cholangiocarcinoma
Deng in the present situation to the influence of human body.Method (ii) is problematic in safety since the concentration of alkaline agent is high.About common
Caustic alkali, its a concentration of 5% or more in the case of, the harmful substance being designated as in poisonous substance and violent in toxicity regulation law, because
This processing is more miscellaneous.In addition, method (iii) due to the generation with poisonous fume, exists in terms of atmosphere pollution
Problem.In turn, method (iv) is not only difficult to that discreet portions are completely exfoliated, but also the danger for keeping the deformation of application fixture damaged
Height, there are the extremely low difficult points of operating efficiency.Method (v) can not entirely prevent the attachment of coating, of high cost, and worry there is application
Shrinkage cavity, therefore do not popularize.By above-mentioned method (i)~method (v), exists and be difficult to all lacking except attachment removal coating
Point.
As other methods, there are following methods：Priming paint is pre-coated with to the part of the attachment coating of application fixture,
After coating adheres to accumulation to a certain extent in coating process, the method removed using water paint remover or solvent
(such as patent document 1).In the case where being removed using water paint remover, with regard to polyvinyl alcohol, polyvinylpyrrolidine
For alkanone, water-soluble propenoic-acids resin, etherified cellulose etc. (patent document 2,3,4,5,6), it can add for using pre-
The equipment such as dipping tank, the drying oven of paint or the process number for increasing them generate the burden in terms of operability, cost.
As the application stripping priming paint of oil type, highly viscous lubricating grease is cheap and effective, therefore is widely used, but
It is to be easy to be dissolved in solvent system coating, or there are shrinkage cavities in water paint, and the coating fallen by unattached is caused to cause
The productivities such as application product are bad reduce, and lubricating grease sheet is as high pollution, therefore the pollution of ambient enviroment also becomes problem.
