一种新型pvc异型材

Novel PVC profiled bar

Abstract

The invention discloses a novel PVC profiled bar. The novel PVC profiled bar is prepared from, by weight, 120-150 parts of polyvinyl chloride, 40-70 parts of nano calcium carbonate modified from silicon fatty acid, 20-60 parts of aluminum silicate fiber, 10-20 parts of antioxidant, 40-60 parts of compound stabilizing lubricant, 20-25 parts of polyacrylonitrile-butadiene-styrene, 3-8 parts of methyl methacrylate, 20-30 parts of MBS auxiliaries, 2-6 parts of ethylene-vinyl acetate copolymer and 3.5-7.5 parts of heat stabilizer. Thermal stability can be improved, the heat-melt performance in the PVC manufacturing process can be ensured, high temperature can be borne, high cold resistance is achieved, and the profiled bar is high in toughness, not prone to damage, high in safety coefficient, capable of saving energy, environmentally friendly, capable of being produced in batches and free of pollution.
本发明公开了一种新型PVC异型材,包括如下重量份数的原料组成:聚氯乙烯120-150份,硅脂酸改性的纳米碳酸钙40-70份,硅酸铝纤维20-60份,抗氧剂10-20份,复合稳定润滑剂40-60份,聚丙烯晴-丁二烯-苯乙烯20-25份,甲基丙烯酸甲酯3-8份,MBS助剂20-30份,乙烯-醋酸乙烯酯共聚物2-6份,热稳定剂3.5-7.5份。本发明能够改善热稳定性、同时能够保证PVC制作过程中的热熔接性能,能够承受较高温度和耐寒性,具有较强的韧性,不易损害且具有较强的安全系数,节能环保的同时能够批量生产,同时环保无污染。
