Abstract

The invention discloses a surface treatment process of a spraying plastic component. The surface treatment process comprises the following steps: grinding flaws including surface particles, pocking marks or burrs and the like on the sprayed plastic component by utilizing a grinding machine; coating a layer of polishing wax on the grinded part; and then carrying out a polishing treatment by utilizing a polishing machine. According to the invention, the operation is simple, any organic solvent is unnecessary, and the purpose of removing of the surface particles, the pocking marks or the burrs on the sprayed plastic component is realized by only adopting the grinding machine and the polishing machine through step-by-step operations, so that the paint cost for multiple spraying operations is saved, the rejection rate of a molded material is greatly reduced, and the qualified product rate of the spraying plastic component is improved. In addition, the surface treatment process also has the advantages that the spraying plastic component is environmental friendly, the cost is low, and a product with surface treatment can be directly packaged and delivered.

Description

A kind of process of surface treatment that sprays plastic parts
Technical field
The present invention relates to processing technique field behind the plastic parts.
Background technology
At present, along with the extensive use of plastic parts, market constantly increases its demand.In order to satisfy the requirement of consumption market, often need carry out certain spraying coating process to plastic parts, increase its aesthetic appearance.Yet, because of the complexity of spraying coating process, receiving the influence of spraying technology, plastic parts is after spraying, and its surface is prone to flaws such as fine particle, pit, burr, thereby has influenced the appearance of spraying plastic parts.The spraying material has expended great amount of manpower and material resources and fund by being molded into spraying, if because of a little flaw influences general effect, and causes scrapping of product, will cause serious waste, and improve production cost greatly.
Summary of the invention
The objective of the invention is to deficiency, provide a kind of and can effectively solve the spraying flaw that plastic rubber member surface occurred to prior art, and easy to operate process of surface treatment.
Above-mentioned purpose of the present invention is achieved through following scheme:
A kind of process of surface treatment that sprays plastic parts; This process of surface treatment is to adopt two kinds of technology of grinding and buffing to combine; Plastic parts to occurring the surface blemish problem after the spraying carries out following process; The sale thereby flaws such as the fine particle that effective removal spraying plastic rubber member surface occurs, pit, burr, the plastic parts after this process of surface treatment is handled can directly come into the market after packing, this process of surface treatment specifically comprises the steps:
Step 1
To spray the surperficial plastic parts defective in back picks out; Said surface plastic parts defective is meant that there is the plastic parts of flaws such as fine particle, pit or burr in the surface;
The abrasive segments that will be used on the sander after 3~5 minutes, is installed on sander leading portion with the polishing sheet that soaked with the clear water immersion;
Step 2
Start sander, polish there being the position of fine particle, pit or burr on the plastic parts of picking out in the step 1; Observe while polishing, watch with naked eyes particle, pit or burr are polished, and do not destroy the plastic rubber member surface skin of paint and exceed, stop polishing;
Step 3
Buffing wax is coated at position to the polishing through step 2 is handled, carries out polishing with polishing machine, and polishing time is 1min.
In the above-mentioned steps 1, abrasive segments adopts PP abrasive segments (polypropylene abrasive segments); Said PP abrasive segments adopts the commercially available prod, and lines adopts fine sand.
In the above-mentioned steps 1; The inventor is through discovering: the dry abrasive segments plastic rubber member surface of directly polishing, very easily gall the skin of paint of plastic rubber member surface, and after abrasive segments soaked 3~5 minutes with clear water; Because abrasive segments is adsorbed with moisture; When the polishing plastic parts, can play the certain protection effect to the plastic rubber member surface skin of paint, the abrasive segments of soaking in addition can effectively be adsorbed the glue ash that produces in the bruting process, plays cleaning action.
In the above-mentioned steps 1, the sander that sander adopts any those skilled in the art to use always all can be realized the present invention, the preferred pneumatic sander of gun type; Process of surface treatment of the present invention is to small-sized spraying plastic parts when handling, and the pneumatic sander of gun type more is prone to realize operation, and is light and handy and control simply, and logical going up stablized one-hand operation behind the air pressure, is convenient to single carrying out.
In the above-mentioned steps 3, buffing wax adopts the plastic cement buffing wax; Said plastic cement buffing wax is the commercially available prod, is commonly called as " Chinese wax ".
In the above-mentioned steps 3, any polishing machine that polishing machine adopts those skilled in the art to use always all can be realized the present invention, preferred small portable pneumatic polisher; Process of surface treatment of the present invention is to small-sized spraying plastic parts when handling, and the small portable polishing machine more is prone to realize operation, and is light and handy and control simply, and logical going up stablized one-hand operation behind the air pressure, is convenient to single carrying out.
In the above-mentioned process of surface treatment; The inventor finds under study for action: in polishing, in the polishing process, because long-time and plastic rubber member surface friction, and impurity such as the glue of absorption generation is grey, dirty easily in abrasive segments and the polishing sponge; Therefore need regularly to change, clean; Thereby help keeping spraying the cleaning of back plastic rubber member surface, the fine particle that can effectively avoid polishing off simultaneously is in polishing process, with the rotation mill flower plastic rubber member surface of polishing sponge; To this situation, in the process of surface treatment of the present invention, the used abrasive segments of sander needed per 30 minutes to change a slice, and the used polishing sponge of polishing machine needed clean once in per 30 minutes.
Plastic parts after the spraying is carried out after above-mentioned process of surface treatment handles, and flaws such as fine particle, pit or burr that its surface exists all are removed, and after packing, get final product shipment.
Compared with prior art, the present invention has following beneficial effect:
1, process of surface treatment of the present invention, it is simple to operate, need not to adopt any organic solvent, only need utilize sander and polishing machine, through the substep operation, can realize removing the purpose of flaws such as spraying plastic rubber member surface particle, pit or burr;
2, process of surface treatment of the present invention not only can be saved the repeatedly paint cost of spraying, reduces scrapping of moulding material greatly, improves the yield of spraying plastic parts, and environmental protection, with low cost, and the product after the processing can be directly through the packing shipment.
The specific embodiment
Below in conjunction with specific embodiment the present invention is done description further, but specific embodiment is not done any qualification to the present invention.
Embodiment
A kind of process of surface treatment that sprays plastic parts, its concrete operations comprise the steps:
Step 1
