Description

technical field [0001] The invention relates to the field of polyurethane elastomers, in particular to a method for preparing polymer environment-friendly radium engraving materials. Background technique [0002] Laser engraving, also called laser engraving or laser marking, is a process of surface treatment using optical principles. ABS resin is obtained by ternary copolymerization of acrylonitrile, butadiene and styrene, and occupies a large share in laser carving products due to its excellent comprehensive performance. Laser engraving (laser marking) has been successfully applied to computer keyboards, light switch covers, automotive interior buttons and door handles, instrument panels, rigid containers and container covers, electrical connectors, capacitors. ABS radium engraving material realizes ABS free of traditional printing process, and is a new technology of energy saving and environmental protection in the electronic and electrical industry. [0003] Although AB...
