Abstract

The invention relates to a halogen-free flame-retardant identification sleeve capable of being subjected to laser etching and a preparation method thereof, and belongs to the technical field of sleeve preparation. By adding a laser etching aid into a base material, the laser absorptivity of a material system is improved, the damage threshold of laser to the material system is reduced, and the technical problems that an existing mark is not clear, poor in permanent resistance, not environmentally friendly and the like are solved; and by using the phosphorus-nitrogen halogen-free flame retardant, the problems of high combustion smoke density, high toxicity and the like of a halogen-containing flame retardant are solved, and the phosphorus-nitrogen halogen-free flame retardant has a wide application prospect.

Description

technical field [0001] The invention relates to a laser-engravable halogen-free flame-retardant marking sleeve and a preparation method thereof, belonging to the technical field of sleeve preparation. Background technique [0002] At present, due to its light weight and scratch resistance, heat-shrinkable marking sleeves have been widely used in the marking fields of electronic appliances, locomotives, ships, aerospace and other cable lines. The marking sleeve that uses ink printing to obtain the marking pattern will easily fade or even fall off over time in an organic solvent environment, losing its marking effect. In addition, the traditional ink printing process for manufacturing marking tubes is complex and inflexible, and there is waste of raw materials, and a large amount of organic solvents in the ink are harmful to human health, which does not meet the current environmental protection needs. [0003] Ordinary marking sleeves contain halogen and have poor solvent res...
