AB S/PVC/玻璃纤维复合材料的制备及性能研究
玻璃纤维拉伸强度高,弹性模量高,可利用玻璃纤维对PVC/ABS合金进行增强改性,使PVC/ABS合金的力学性能得到一定程度的提高。
本研究将玻璃纤维加入比例为70:30的AB S/PVC合金中实现对AB S/PVC的增强改性,通过改变玻璃纤维的加入量来研究玻璃纤维对AB S/PVC合金性能的影响,并探究了经硅烷偶联剂改性后的玻璃纤维对AB S/PVC合金性能的影响。

ZB/M003复配型阻燃抑烟剂对PVC抑烟行为的影响
聚氯乙烯具有很多优良的性能,如易改性、耐磨损、价格低、光老化性能好,使用寿命长等,而被广泛使用与建材、食品、纺织等领域[1]。同时因其高达56.74%的氯含量,其硬质品具有难燃,自熄等阻燃特性。但PVC制品在燃烧时,生烟量大,其烟密度高达720(以Rohm&Hass XP-2烟箱测定)[2],并有苯、甲苯、萘芳香族物质生成,因此,对PVC建材而言,抑烟比阻燃更为重要。钼系化合物为迄今为止发现的抑烟效果最好的阻燃抑烟剂,其特点不...

PVC 薄膜的表面改性及化学镀银
关键字:Surface modification, Roughening, Sensitization, Activation 对PVC 薄膜的表面改性的步骤可分为表面粗化、敏化、活化处理三步,粗化是使用硅烷偶联剂对其进行表面改性,使PVC 表面由疏水性变为亲水性,而后再用氯化亚锡(SnCl2)对其进行敏化反应,最后用氯化钯(PbCl2)进行活化处理。

力化学方法增韧耐热聚氯乙烯材料
关键字:PVC 韧性 聚氯乙烯的耐热改性剂一般具有极性官能团或环状结构,加入PVC中能提高材料的热性能。但会引起材料韧性的下降,本文加入一定量的纳米碳酸钙,通过自制的球磨机对α-甲基苯乙烯型耐热改性剂和纳米级碳酸钙粒子共振磨,再加入PVC中,在不影响材料热性能的提高前提下来改善材料的韧性。
