Abstract
The invention discloses a surface repairing process of a plastic product. The surface repairing process of the plastic product comprises the following steps of firstly, cleaning the plastic product to be repaired, removing impurities at the surface; selecting proper polrvinyl chloride particles, and putting the polrvinyl chloride particles into an injection molding machine; carrying out warming treatment on the polrvinyl chloride particles in the injection molding machine until the polrvinyl chloride particles completely become into a molten state; finally filling the polrvinyl chloride particles in the molten state to the surface of the plastic product through the injection molding machine, and then spraying at the surface of the plastic product to form a physical protection layer. The surface repairing process has the beneficial effects that the operation is simple by improving the existing plastic surface repairing technology; and the repaired plastic product has the physical protection layer. Thus, secondary injury is effectively prevented; the defects in the prior art are overcome; and the target of the surface repairing process is achieved.
Description
Technical field
The present invention relates to field of plastic products, specifically, specially refer to a kind of surface repairing technique of plastic product.
Background technology
Plastics are synthetic macromolecular compound { polymer (polymer) }, can be described as again macromolecule or giant molecule (macromolecules), be also plastics (plastics) or the resin (resin) that generally is commonly called as, can freely change the body pattern.Be the material that utilizes raw material monomer to be polymerized with synthetic or condensation reaction, formed by additives such as synthetic resin and filler, plasticizer, stabilizing agent, lubricant, colorants.
The main component of plastics is synthetic resin.This noun of resin is to be gained the name by the oozy lipid of animals and plants at first, and as rosin, shellac etc., resin refers to not yet the high polymer that mixes with various additives.Resin accounts for 40%～100% of plastics gross weight.The key property of plastics depends mainly on the person's character of resin, but additive also plays an important role.Some plastics is comprised of synthetic resin basically, does not contain or contain less additive, as organic glass, polystyrene etc.
Application number is that 201210088537.9 patent application document discloses a kind of technique for treating plastic surface, and comprise the following steps: a. processes semi-finished product: the screening plastic pellet, carry out heat treatment twice, and with the plastic pellet plastics sucking moulding, generate semi-finished product; B. spray paint: spray paint on half-finished coat of metal; C. plating: surface of semi-finished is cleaned, remove impurity, plate metal in surface of semi-finished; D. carve characters: by mould, semi-finished product are carved characters, generate finished product.The defective of this technique is to be simple the plastics envelope to be carried out repair, does not have further precautionary measures.
In sum, for the defective of prior art, need especially a kind of surface repairing technique of plastic product, to solve the deficiencies in the prior art.
Summary of the invention
The object of the present invention is to provide a kind of surface repairing technique of plastic product; by existing frosting renovation technique is improved; simple to operate; repair complete plastic product and have the physical protection layer; thereby effectively prevented secondary damage; overcome the deficiency in the conventional art, realized purpose of the present invention.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of surface repairing technique of plastic product, it comprises the steps:
1) at first clean the plastic product that needs reparation, remove the impurity that its surface is contained;
2) then choose appropriate particulate polyvinyl chloride, then particulate polyvinyl chloride is put into injection machine;
3) then the particulate polyvinyl chloride in injection machine is carried out heat treatment, until particulate polyvinyl chloride integral body becomes molten condition;
4) by injection machine, the particulate polyvinyl chloride of molten condition is filled at last the surface of plastic product, then spraying paint on the surface of plastic product forms the physics protective layer.
In one embodiment of the invention, the temperature of the heat treatment technique in described step 4) is 150-180 ℃, and the duration is 30 minutes.
In one embodiment of the invention, the thickness of described physical protection layer is the 0.2-0.5 millimeter.
Beneficial effect of the present invention is: by existing frosting renovation technique is improved; simple to operate, repair complete plastic product and have the physical protection layer, thereby effectively prevented secondary damage; overcome the deficiency in the conventional art, realized purpose of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
The surface repairing technique of a kind of plastic product of the present invention, it comprises the steps:
1) at first clean the plastic product that needs reparation, remove the impurity that its surface is contained;
2) then choose appropriate particulate polyvinyl chloride, then particulate polyvinyl chloride is put into injection machine;
3) then the particulate polyvinyl chloride in injection machine is carried out heat treatment, until particulate polyvinyl chloride integral body becomes molten condition;
4) by injection machine, the particulate polyvinyl chloride of molten condition is filled at last the surface of plastic product, then spraying paint on the surface of plastic product forms the physics protective layer.
Especially it is pointed out that for fully with the particulate polyvinyl chloride melting, the temperature of the heat treatment technique in described step 4) is 150-180 ℃, the duration is 30 minutes.By adopting above-mentioned technique, effectively guaranteed the repairing quality of subsequent technique.
Thickness that it should be noted that described physical protection layer is the 0.2-0.5 millimeter, neither changes the lightness of plastic product integral body, the secondary damage of the plastic product after preventing again to repair.
Beneficial effect of the present invention is: by existing frosting renovation technique is improved; simple to operate, repair complete plastic product and have the physical protection layer, thereby effectively prevented secondary damage; overcome the deficiency in the conventional art, realized purpose of the present invention.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
