Description
Technical field
The present invention relates to plastics processing fields, and in particular to a kind of method for processing plastic surface.
Background technique
Plastics can be divided into thermoplastic and thermosetting plastics two major classes.In general, thermosetting plastics wants specific heat
Thermoplastic plastic is easy to be glued.But their surface energy is below the hydrophilic materials such as glass, ceramics, metal, and their tables
Face can often adhere to release agent or evolution plasticizer, therefore be not easy to be infiltrated by adhesive, to influence glue-joint strength.Therefore, one
As be both needed to be surface-treated plastics.Since the kind of plastics is numerous, various performance differences are very big, therefore the side being surface-treated
Method is also just quite different.
Summary of the invention
The present invention is intended to provide a kind of method for processing plastic surface, this method overcome prior art defect, there is operation letter
Just, the good feature of flexibility after handling.
Technical scheme is as follows:
A kind of method for processing plastic surface, the treating method comprises following steps:

B, oxidizing flame handle, be first roughened frosting with emery cloth, then plastics are placed on oxidizing flame and are calcined, be divided into three times into
Row calcining, calcines 3-5s every time；
C, it after impregnating 3-5min with sodium hydroxide solution, then is rinsed with cold water；
D, it is activated, impregnates 5-12min in the mixed solution of chromic acid and the concentrated sulfuric acid；
E, oxidation processes aoxidize 5-10min in the mixed solution of potassium bichromate and the concentrated sulfuric acid；
F, 5-7min is washed in 70-75 DEG C of hot water, is dried under the conditions of 65-75 DEG C after being cleaned with distilled water；
G, coating is uniformly coated on the surface of plastics, its component of coating presses following weight proportion: poly- propylhomoserin acrylic acid 5-
10 parts, 3-8 parts of Sodium Polyacrylate, 1.8-3.5 parts of phenolic resin, 0.8-2.3 parts of acrylate and vinyl acetate emulsion, hexylene glycol butyl ether sodium acetate 0.2-
0.6 part；
H, 10-20min is dried under the conditions of 65-75 DEG C.
Preferably, the degreasing solvent is acetone or butanone.
Preferably, the mass fraction of the sodium hydroxide solution is 30%, and dipping temperature is 60-75 DEG C.
Preferably, the mass ratio of chromic acid, the concentrated sulfuric acid and water is 1:2:4, dipping temperature in the mixed solution in the step D
It is 60-75 DEG C.
Preferably, the mass ratio of potassium bichromate, the concentrated sulfuric acid and water is 1:5:34, oxygen in the mixed solution in the step E
Changing temperature is 65-75 DEG C.
Preferably, the step F is specially to wash 5-7min in 70-75 DEG C of hot water, in 70- after being cleaned with distilled water
It is dried under the conditions of 80 DEG C.
Preferably, the coating composition further includes 5-7 parts diatomite part.
The invention has the advantages that method for processing plastic surface simple process of the invention, treated plastic cement
It is easy to connect, and glue-joint strength is high；Also, by being coated with one layer of fine and close coating in surface of plastic matrix, it is basic to improve plastics
The toughness of itself extends it using the time, while the color of coating itself can be changed, with different-style of arranging in pairs or groups out, difference taste
Appearance, more cater to the needs in market；And the flexibility for changing coating itself, is allowed to more easily be bonded, is not easy to peel off, prolong
The service life of long plastics is allowed to be hardly damaged, and is more in line with public demand.
