Problems solved by technology

However, when forming characters or patterns on the surface of plastic parts made of these raw materials in the prior art, generally only ink screen printing method can be used. However, the mimeograph method, which has been traditional for many years, is complicated to operate, the work efficiency is too low, and the cost is too high, resulting in Environmental pollution, products are not environmentally friendly
Moreover, this traditional mimeograph method cannot work on irregular platforms, especially it cannot realize the formation of characters or patterns in hidden places such as slits or openings
In addition, the characters or patterns formed by the mimeograph method do not have acid, alkali, oil resistance, poor wear resistance, and are easy to fall off.
Due to the limitation of existing raw materials, the molded plastic products cannot be laser engraved to form continuous and smooth characters or patterns

Abstract

The invention relates to a resin composition and a production method of a plastic product of the resin composition. The resin composition comprises the following components by weight percent: 50-99.999% of basic resin and 0.001-50% of carbonization accelerator, wherein the basic resin is selected from one or a mixture formed by more of acrylonitrile butadiene styrene (ABS), high impact polystyrene (HIPS), polycarbonate (PC), propene polymer (PP) or poly ethylene (PE); and the carbonization accelerator is selected from one or mixture formed by more of phosphorus or a phosphorus-containing compound, bromine or a bromine-containing compound, chlorine or a chlorine-containing compound, antimony or antimony-containing compound, boron or boron-containing compound. The resin composition is suitable for laser carving to form words or patterns, and the formed words or patterns have less possibility of falling off and are environment-friendly. The preparation method has the advantages of high work efficiency and low cost.

Description

technical field [0001] The invention relates to a resin composition for preparing plastic parts of products such as cards, telephones, computer keyboards, fax machines and a method for preparing the plastic parts. The resin composition is suitable for laser engraving. Background technique [0002] The plastic parts of products such as cards, telephones, computer keyboards, and fax machines are generally injection-molded with resin materials such as ABS (acrylonitrile-butadiene-styrene), HIPS (high-impact polystyrene), and the like. However, when forming characters or patterns on the surface of plastic parts made of these raw materials in the prior art, generally only ink screen printing method can be used. However, the mimeograph method, which has been traditional for many years, is complicated to operate, the work efficiency is too low, and the cost is too high, resulting in Environmental pollution, products are not environmentally friendly. Moreover, this traditional mime...
