性能
PVC树脂(polyvinylchloride)是重要的有机合成材料之一。英文名称:Polyvinyl Chloride,化学结构式:(CH2-CHCL)n,其产品具有良好的物理性能和化学性能,广泛用于工业、建筑、农业、日用生活、包装、电力、公用事业等领域。
物理属性
PVC树脂,物理外观为白色粉末,无毒、无臭。相对密度1.35-1.46,折射率1.544(20℃)不溶于水,汽油,酒精和氯乙烯,溶于丙酮,二氯乙烷,二甲苯等溶剂,化学稳定性很高,具有良好的可塑性。除少数有机溶剂外,常温下可耐任何浓度的盐酸、90% 以下的硫酸、50-60%的硝酸及20%以下的烧碱,此外,对于盐类亦相当稳定;PVC在火焰上能燃烧并放出HCl,但离开火焰即自熄,是一种“自熄性”、“难燃性”物质;PVC在100℃以上开始分解并缓慢放出HCl,随着温度上升,分解与释放HCl速度加快,致使PVC变色。
组成
PVC是由氯乙烯通过自由基聚合而合成的。由悬浮聚合法、乳液聚合法和本体聚合法,以悬浮聚合法为主,约占PVC总产量的80%左右。行业内一般将PVC生产工艺依据氯乙烯单体的获得方法来区分,可分为电石法、乙烯法和进口(EDC、VCM)单体法(习惯上把乙烯法和进口单体法统称为乙烯法)。根据生产方法的不同,PVC纯粉分为:通用型PVC树脂、高聚合度PVC树脂、交联PVC树脂。通用型PVC树脂是由氯乙烯单体在引发剂的作用下聚合形成的;高聚合度PVC树脂是指在氯乙烯单体聚合体系中加入链增长剂聚合而成的树脂;交联PVC树脂是在氯乙烯单体聚合体系中加入含有双烯和多烯的交联剂聚合而成的树脂。
工艺方法
有悬浮聚合法、乳液聚合法和本体聚合法,以悬浮聚合法为主,约占pvc总产量的80%左右。
(1)悬浮聚合法使单体呈微滴状悬浮分散于水相中,选用的油溶性引发剂则溶于单体中,聚合反应就在这些微滴中进行,聚合反应热及时被水吸收,为了保证这些微滴在水中呈珠状分散,需要加入悬浮稳定剂,如明胶、聚乙烯醇、甲基纤维素、羟乙基纤维素等。引发剂多采用有机过氧化物和偶氮化合物,如过氧化二碳酸二异丙酯过氧化二碳酸二环己酯、过氧化二碳酸二乙基己酯和偶氮二异庚腈、偶氮二异丁腈等。聚合是在带有搅拌器的聚合釜中进行的。聚合后,物料流入单体回收罐或汽提塔内回收单体。然后流入混合釜,水洗再离心脱水、干燥即得树脂成品。
(2)乳液聚合法最早的工业生产 PVC的一种方法。在乳液聚合中,除水和氯乙烯单体外,还要加入烷基磺酸钠等表面活性剂作乳化剂,使单体分散于水相中而成乳液状,以水溶性过硫酸钾或过硫酸铵为引发剂。[1]
型号参数
主要用途
PVC树脂可加工成各种塑料制品,按其用途可分为软质和硬质产品二大类,主要用于生产透明片、管件、金卡、输血器材、软、硬管、板材、门窗、异型材、薄膜、电绝缘材料、电缆护套、输血料等。
一般软硬质制品
利用挤出机可以挤成软硬管、电缆、电线等;利用注射成型机配合各种模具,可制成塑料凉鞋、鞋底、拖鞋、玩具、等日用品和汽车及电器配件等。
硬质管材及异型材
相对其他的塑料而言PVC的耐老化性能优良,冲击强度和韧性较高,价格低廉,适合做排水管等各种建筑用管材,及型材异型材。
薄膜
PVC与添加剂混合、塑化后,利用三辊或四辊压延机制成规定厚度的透明或着色薄膜,用这种方法加工薄膜,成为压延薄膜。也可以通过剪裁,热合加工包装袋、雨衣、桌布、窗帘、充气玩具等。宽幅的透明薄膜可以供温室、塑料大棚及地膜之用。经双向拉伸的薄膜,所受热收缩的特性,可用于收缩包装。
涂层制品
有衬底的人造革是将PVC糊涂敷于布上或纸上,然后在100摄氏度以上塑化而成。也可以先将PVC与助剂压延成薄膜,再与衬底压合而成。无衬底的人造革则是直接由压延机压延成一定厚度的软制薄片,再压上花纹即可。人造革可以用来制作皮箱、皮包、书的封面、沙发及汽车的坐垫等,还有地板革,用作建筑物的铺地材料。
泡沫制品
软质PVC混炼时,加入适量的发泡剂做成片材,经发泡成型为泡沫塑料,可作泡沫拖鞋、凉鞋、鞋垫、及防震缓冲包装材料。也可用挤出机基础成低发泡硬PVC板材和异型材,可替代木材试用,是一种新型的建筑才材料。
透明片材
PVC中加冲击改性剂和稳定剂,经混合、塑化、压延而成为透明的片材。利用热成型可以做成薄壁透明容器或用于真空吸塑包装,是优良的包装材料和装饰材料。
硬板和板材
PVC中加入稳定剂、润滑剂和填料,经混炼后,用挤出机可挤出各种口径的硬管、异型管、波纹管,用作下水管、饮水管、电线套管或楼梯扶手。将压延好的薄片重叠热压,可制成各种厚度的硬质板材。板材可以切割成所需的形状,然后利用PVC焊条用热空气焊接成各种耐化学腐蚀的贮槽、风道及容器等。
