Abstract

The invention belongs to the technical field of resin compositions and particularly relates to a glass fiber reinforced flame retardant polybutylene terephthalate resin composition with a laser engraving function and a preparation method thereof. The composition comprises, by weight, 43.2 to 73.2 parts of polybutylene terephthalate, 0 to 40 parts of continuous glass fibers, 9.5 to 15 parts of halogen flame-retardants, 3 to 5 parts of antimony trioxide, 3 to 5 parts of toughening agents, 0 to 0.5 part of coupling agents, 0.3 to 1.0 part of laser additives, 0.3 to 0.5 part of antioxidants, 0.3 to 0.5 part of lubricating agents and 0 to 0.5 part of carbon black. The resin composition simultaneously has good mechanical property, flame retardant property and laser marking performance, and evident laser marks in black, white or gray and the like can be made in a laser etching mode on matrices in different colors by the composition.

Description

technical field [0001] The invention belongs to the technical field of resin composition preparation, and in particular relates to a glass fiber reinforced flame-retardant polybutylene terephthalate resin composition with laser engraving function and a preparation method thereof. Background technique [0002] Product marking is becoming more and more important in industry, especially plastic products, which have a wide range of applications. Production dates, barcodes, company slogans, serial numbers, etc. need to be marked on products frequently. And commonly used marking technology such as printing, embossing, pasting printing etc., these technologies exist that the printing operation is very complicated, and skilled workers and a lot of time are needed. Furthermore, it is quite difficult to mark characters or symbols on irregular surfaces using the techniques described above. The advantages of laser non-contact and high-speed marking make the importance of laser marking ...
