阅读说明：本技术 一种用于激光焊接的全生物降解塑料组件 (Full-biodegradable plastic component for laser welding ) 是由 张海涛 李宇红 刘岚 王飞 刘雨晴 于 2021-07-06 设计创作，主要内容包括：本发明提供了一种用于激光焊接的全生物降解塑料组件,属于激光焊接塑料制备技术领域。本发明提供的塑料组件由透光塑料件和吸热塑料件组成,所述透明塑料件以改性聚乳酸为基体树脂,所述吸热塑料件以聚己二酸/对苯二甲酸丁二醇酯为基体树脂,吸热塑料件中激光吸收剂以杂环共轭聚合物为吸光剂主剂。本发明提供的塑料组件能够满足激光焊接要求,同时具有全生物降解特点,不会产生“白色污染”,将会在人们的环保意识逐渐增强的社会氛围内获得广泛应用。(The invention provides a full-biodegradable plastic component for laser welding, and belongs to the technical field of laser welding plastic preparation. The plastic component provided by the invention comprises a light-transmitting plastic part and a heat-absorbing plastic part, wherein the transparent plastic part takes modified polylactic acid as matrix resin, the heat-absorbing plastic part takes poly adipic acid/butylene terephthalate as matrix resin, and a laser absorber in the heat-absorbing plastic part takes a heterocyclic conjugated polymer as a main agent of the light absorber. The plastic component provided by the invention can meet the laser welding requirement, has the characteristic of full biodegradation, does not generate white pollution, and can be widely applied in social atmosphere with gradually enhanced environmental awareness of people.)
