Description
(一)技术领域 (1) Technical field
本发明涉及环保阻燃聚合物材料，尤其涉及一种阻燃改性的聚合物材料，这种聚合物材料为符合RoHS指令要求的环保阻燃ABS专用料，本发明还涉及环保阻燃ABS专用料的制备方法。The invention relates to an environmentally friendly flame-retardant polymer material, in particular to a flame-retardant modified polymer material. This polymer material is a special material for environmentally friendly flame-retardant ABS that meets the requirements of the RoHS directive. The preparation method of the material.
(二)背景技术 (2) Background technology
ABS树脂具有优良的冲击性，高刚性，耐油性，耐低温性，耐化学腐蚀性和电气性能，在电器、电子等领域有广泛用途。ABS树脂(丙烯腈-苯乙烯-丁二烯共聚物，ABS是Acrylonitrile Butadiene Styrene的首字母缩写)是一种强度高、韧性好、易于加工成型的热塑型高分子材料。ABS树脂是丙烯腈(Acrylonitrile)、1，3-丁二烯(Butadiene)、苯乙烯(Styrene)三种单体的接枝共聚物。它的分子式可以写为(C8H8·C4H6·C3H3N)x，但实际上往往是含丁二烯的接枝共聚物与丙烯腈-苯乙烯共聚物的混合物，其中，丙烯腈占15％～35％，丁二烯占5％～30％，苯乙烯占40％～60％，最常见的比例是A:B:S＝20:30:50，此时ABS树脂熔点为175℃。但ABS树脂的氧指数只有18左右，容易引起燃烧而导致火灾。随着社会发展和社会安全意识的日益提高，在电子电器领域使用阻燃ABS已成为社会共识。目前，生产阻燃ABS的阻燃剂主要采用多溴二苯醚和三氧化锑的复配物(高分子材料科学与工程，2005年，第27卷，第3期)。自1986年欧洲首先发现多溴二苯醚类物质在燃烧时可能产生四溴代双苯并二噁烷及四溴代双苯并呋喃(塑料，2005年，34卷。第1期)等致癌物质，在阻燃时危害人员安全和污染环境，因此，欧盟颁布了《关于在电子电气设备中禁止使用某些有害物质指令》(简称《RoHS指令》)，规定阻燃塑料中所含的多溴联苯和多溴联苯醚的含量不得超过1000PPM。ABS resin has excellent impact resistance, high rigidity, oil resistance, low temperature resistance, chemical corrosion resistance and electrical properties, and is widely used in electrical appliances, electronics and other fields. ABS resin (acrylonitrile-styrene-butadiene copolymer, ABS is the acronym for Acrylonitrile Butadiene Styrene) is a thermoplastic polymer material with high strength, good toughness and easy processing. ABS resin is a graft copolymer of acrylonitrile (Acrylonitrile), 1,3-butadiene (Butadiene), styrene (Styrene) three monomers. Its molecular formula can be written as (C8H8 C4H6 C3H3N)x, but in fact it is often a mixture of butadiene-containing graft copolymer and acrylonitrile-styrene copolymer, of which acrylonitrile accounts for 15% to 35%. , butadiene accounts for 5% to 30%, styrene accounts for 40% to 60%, and the most common ratio is A:B:S=20:30:50. At this time, the melting point of ABS resin is 175°C. However, the oxygen index of ABS resin is only about 18, which is easy to cause combustion and cause a fire. With the development of society and the increasing awareness of social safety, the use of flame-retardant ABS in the field of electronic appliances has become a social consensus. At present, the flame retardant for the production of flame-retardant ABS mainly uses the compound of polybrominated diphenyl ether and antimony trioxide (Polymer Materials Science and Engineering, 2005, Vol. 27, No. 3). Since 1986, it was first discovered in Europe that polybrominated diphenyl ethers may produce tetrabromodibenzodioxane and tetrabromodibenzofuran (Plastic, 2005, Vol. 34. No. 1) and other carcinogenic substances when burned Substances that endanger personnel safety and pollute the environment when they are flame retardant, therefore, the EU promulgated the "Directive on the Prohibition of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" ("RoHS Directive"), which stipulates that polybrominated biphenyls contained in flame-retardant plastics And the content of polybrominated diphenyl ethers shall not exceed 1000PPM.
