Abstract

The invention discloses a polyethylene laser marking master batch as well as a preparation method and application thereof. The polyethylene laser marking master batch comprises the following components in parts by weight: 45-70 parts of a polyethylene matrix, 10-15 parts of a polystyrene-based copolymer, 15-30 parts of layered-structure mineral particles, 5-10 parts of a compatilizer, 1-2 parts of a lubricant and 0.1-0.3 part of a cross-linking sensitizer, wherein the silicon content of the layered structure mineral particles is greater than or equal to 30 wt.%. The polyethylene laser marking master batch provided by the invention has excellent laser sensitivity. The polyethylene laser marking master batch is added into polyethylene according to a weight ratio of 5-10%, and a prepared polyethylene material has excellent laser marking performance and can be used for preparing an optical cable sheath.

Description

technical field [0001] The invention relates to the field of polymer materials, and more specifically, relates to a polyethylene laser marking masterbatch and its preparation method and application. Background technique [0002] The traditional product marking technology mainly adopts ink pad printing, coding marking, etc. It has the advantages of wide color selection and wide range of applicable materials, but this technology has disadvantages such as environmental friendliness and poor durability. Laser marking is a new type of environmental protection marking technology. It mainly uses high-energy-density laser beams to act on the target to cause physical or chemical changes on the surface to obtain visible patterns. Laser marking technology is widely used in text on plastic surfaces and patterned markings. [0003] According to product requirements, the surface of the optical cable sheath must be marked with product name, manufacturer, length and other information at ce...
