A polishing method for high-gloss coating of plastic processing parts

Abstract

The invention provides a method for polishing a highlight coating of a plastic machined part. The method includes the steps of firstly, manufacturing a special polishing head, namely, an ordinary wool polishing head is smeared with polishing paste , and the ordinary wool polishing head is pressed and rotated, so that a uniform polishing paste coating is formed on the ordinary wool polishing head, and the special polishing head is manufactured; secondly, smearing the polishing paste, namely, the surface of the plastic machined part is uniformly smeared with the polishing paste; thirdly, polishing, namely, the special polishing head manufactured through the first step is rotated and rubbed on the plastic machined part coated with the polishing paste, and the surface of the plastic machined part is polished. Through technique improvement, the plastic machined part can be directly polished, operation is easy and convenient to conduct, the defects that a polishing layer of the plastic machined part is abraded and the polishing head needs to be repeatedly cleaned after water polished is conducted on the plastic machined part is polished through traditional abrasive paper are overcome, and the method has the advantages that operation is easy and convenient to conduct, polishing efficiency is high, and energy saving and environment friendliness are achieved.

Description

technical field [0001] The invention relates to a polishing method for a plastic processed part, in particular to a polishing method for a high-gloss coating of a plastic processed part. Background technique [0002] With the continuous development of injection molding technology, high-gloss plastic parts are used more and more. Existing plastic polishing technology is generally to first polish with 2000-3000 mesh sandpaper, then apply the polishing paste on the polished product and polish it with a wool throwing head. There are following defects in the above-mentioned method: 1, adopt sandpaper to carry out water polishing, and sandpaper can wear plastic parts, cause sand marks to be left on the plastic parts; 2, existing polishing paste is mostly white paste, adopts white polishing paste to polish, After the processing is completed, the plastic parts will produce whitening phenomenon; 3. Since the sandpaper is used for water grinding first, and then the polishing head is ...

Problems solved by technology

There are following defects in the above-mentioned method: 1, adopt sandpaper to carry out water polishing, and sandpaper can wear plastic parts, cause sand marks to be left on the plastic parts; 2, existing polishing paste is mostly white paste, adopts white polishing paste to polish, After the processing is completed, the plastic parts will produce whitening phenomenon; 3. Since the sandpaper is used for water grinding first, and then the polishing head is used for polishing, the residual sand on the polished object will cause wool throwing stains. Therefore, in the polishing process of plastic parts, it is necessary to Repeated cleaning of the polishing head, firstly, wastes manpower, secondly, causes waste of water resources, pollutes the environment, thirdly, increases the processing cost of plastic parts
