Description
Technical field
The present invention relates to plastic products depainting technical field, specifically a kind of plastic workpiece surface depainting processing method.
Background technique
Plastics because its light weight, will not corrode, good insulating, low thermal conductivity the features such as be widely used in produce or live
On articles.In order to protect the surface of plastic part, enhance its surface property, prolong its service life, it will usually in the table of plastic part
Face coats coating, the plastic products that defect needs the plastic part done over again or recycling occurs for spray painting, is required to carry out
Depainting processing, to be coated or be recycled again.
The removing of old paint film has physics and chemical two methods.Physical method includes flame method, blast method, sand-blast etc..
But plastics are had damage, it is larger to the nocuity of substrate.Chemical method uses paint stripper to remove paint film.Paint stripper
Depainting principle is to pass through dissolution, infiltration, swelling, removing and reaction according to " similar to mix " and " solubility parameter is close " principle
Equal a series of physical, chemical process are realized.
But existing plastic chemistry stripping method there are paint removal efficiencies low, the big problem of chemical agent usage amount, in addition,
Industrial chemical stripper used usually contains more methylene chloride, phenol, easy volatile solvent and some other nuisance
Matter, to cause the volatility of paint stripper and toxicity all larger, and very big to the corrosivity of plastic workpiece, this makes plastics
The rate of recovery of workpiece substantially reduces.
Summary of the invention
