Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to a material for laser engraving and a preparation method thereof. Background technique [0002] With the development of science and technology and the progress of society, electronic and electrical products have played a very important role in people's lives. Existing electronic and electrical products often need to engrave or print patterns on their surfaces. Laser engraving is an emerging surface treatment process, also known as laser engraving, which uses numerical control technology as the basis, laser as the processing medium, and the processing materials are instantly melted and vaporized under laser engraving irradiation. Carving achieves the purpose of processing. Laser engraving is the use of laser technology to engrave text and patterns on objects. The surface of the words or patterns engraved by this technology is still relatively smooth, and the writing is dif...
