Laser engraving material for plastic products and preparation method thereof

Abstract

The invention discloses a laser engraving material for plastic products, and the laser engraving material is prepared by the following components in percent by mass: 30-45% of ethylene-butene copolymer (SEBS), 1.5-2.5% of silicone, 5.20% of PP (Propene Polymer), 5-15% of white oil, 5.5-10% of metal oxide powder, 2-20% of processing aid, 2-13% of filler and 3-5% of laser additive. The invention also discloses a preparation method of the laser engraving material for plastic products, and the method comprises the steps of burdening, stirring, extrusion, cooling, granulation and the like. According to the laser engraving material for plastic products, the problem that the common plastic materials cannot undergo laser engraving and are easy to be fired and fused is overcome, the display of special colors during the laser is realized so that the engraved images and texts directly display colors without coloring process after the engraving, and the process is reasonable; and the laser engraving material for plastic products is particularly suitable for the high-end products such as earphone wires and the like.

Description

technical field [0001] The invention relates to the field of earphone products, in particular to a laser engraving material for plastic products and a preparation method thereof. Background technique [0002] At present, the preparation and anti-counterfeiting of many high-end products generally use laser engraving technology. Laser engraving refers to laser engraving, which is to engrave traces through the chemical and physical changes of surface materials caused by the light energy of the laser beam, or to burn part of the material through light energy, and to display the graphics and characters to be etched; laser engraving is Shooting lasers on almost all materials such as wood products, acrylic, plastic panels, metal panels, stone, etc., is becoming more and more widely used. However, plastic materials are important raw materials for earphone products. Due to the disadvantages of ordinary plastic materials such as poor heat resistance, they are easily deformed and melt...

AI Technical Summary

Problems solved by technology

[0008] The present invention focuses on solving the problem that ordinary plastic materials cannot be used for laser engraving. By adding metal oxides of different colors to the formula of ordinary plastic materials, the plastic can be gasified or engraved by adjusting the power of the laser beam during laser engraving. Carbonization, and the colored metal oxides used are not vaporized but deposited on the bottom layer of the engraved graphics, showing special colors, saving subsequent coloring processes, and no need to add additional processes to color after engraving
