废旧线路板材非金属粉末/
不饱和聚酯树脂复合材料的性能研究
摘 要
不饱和聚酯树脂，英文名称UPR，一般是由不饱和二元酸二元醇或者饱和二元酸不饱和二元醇缩聚而成的具有酯键和不饱和双键的线型高分子化合物。通常，聚酯化缩聚反应是在190～220℃进行的。直至达到预期的酸值（或粘度），在聚酯化缩反应结束后，趁热加入一定量的乙烯基单体，配成粘稠的液体，这样的聚合物溶液称之为不饱和聚酯树脂。传统的废旧线路板通过回收得到的基板粉料一般通过焚烧回收热值，或是作为粉料用于涂料、铺路材料。在焚烧过程中这些有机粉料会释放出溴苯、溴甲苯等有毒气体，不仅对环境产生二次污染而且造成了很大的资源浪费。
本文主要介绍按照质量比100:5、100:10、100:15、100:20称取不饱和聚酯树脂和非金属粉末制作未改性浇注体，与按照质量比100:10称取不饱和聚酯和非金属粉末制备不同偶联剂改性浇注体别进行弯曲、拉伸等力学性能测试，分析其弯曲力和拉伸力分别于弯曲模量与拉伸模量的关系。制成复合材料，大大提高了资源的综合利用，同时变废为宝，产生经济效益。

Abstract
Unsaturated polyester resin， English name of UPR， usually by unsaturated or saturated dibasic acid dibasic acid glycol unsaturated glycol polycondensation of with ester bond of linear polymers and unsaturated double bond. Usually， the polyester melt polycondensation reaction was conducted in 190 ~ 220 ℃. Until the desired acid value (or viscosity)， at the end of the polyester melt condensation reaction， add a certain amount of vinyl monomer， match into sticky liquid， the polymer solution is called unsaturated polyester resin. The traditional waste PCB substrate powder is obtained by recycling generally by burning recycling calorific value， or as a powder used in paint and road pavement. In the process of burning of the organic powder can release bromobenzene， the toxic gas such as bromine toluene， not only produce secondary pollution to the environment but also caused great waste of resources.
This paper mainly introduces according to quality than 100:5， 100:10， 100， 15， 100:20 weigh and unsaturated polyester resin and non-metallic powder production unmodified casting body， and according to the quality than 100:10 said in unsaturated polyester and nonmetal powder preparation of different coupling agent modification casting body dont mechanical properties such as bending， tensile test， analysis of the bending force and tensile force， respectively in bending modulus and the relationship between the tensile modulus. Made from composite materials， greatly improving the comprehensive utilization of resources， at the same time to generate economic benefits.
