Abstract

The invention relates to the technical field of infrared light excited carbonization auxiliary agents, and provides an infrared light excited carbonization auxiliary agent. The infrared light excitedcarbonization auxiliary agent at least comprises the following components of, in parts raw material, 0.01-0.15 part of metal powder, 35-55 parts of metal oxide, 15-30 parts of semi-aromatic polyamide,2-4 parts of compatilizer and 20-35 parts of carrier resin. The prepared infrared light excited carbonization auxiliary agent can be suitable for different types of polymer matrix materials, such asPP, PE, PET, PS, PVC, PC and other plastics can form very obvious color contrast, and the infrared light excited carbonization auxiliary agent can not change the color and characteristics of the product, absorb enough laser to raise the local temperature to burn or foam plastic, and improve the identification effect, especially the color difference contrast is the most excellent when the mark is applied to the PP polyolefin resin.

Description

technical field [0001] The present invention relates to the technical field of infrared light-excited carbonization aids, and more specifically relates to an infrared light-excited carbonization aid and its preparation method and application. Background technique [0002] The traditional method of marking on the plastic surface is printing, but the cost is high, it is not environmentally friendly, and it is easy to wipe off. Laser engraving refers to the use of a laser beam to act on the material to cause a change in the shape or performance of the sample. It is a high-power-density spot formed by focusing the laser beam. In a few microseconds, the temperature of the spot area rises to the melting point or even the boiling point of the material. Make the material at the irradiated place melt and vaporize, ablate or reach the ignition point immediately. When the laser beam moves along the set path, the photons interact with the material continuously, and at the same time, th...
