Description

一种高光镜面PVC板及其制备方法
技术领域
本发明属于板材技术领域，具体涉及一种高光镜面PVC板及其制备方法。
背景技术
PVC板是以PVC为原料制成的截面为蜂巢状网眼结构的板材。PVC板在建材行业占的比重最大，为60％，其次是包装行业，还有其他若干小范围应用的行业。按照软硬程度可分为软PVC和硬PVC。按制作工艺可分为PVC结皮发泡板和PVC自由发泡板。按透明和不透明可分为PVC透明板和PVC板。pvc板聚氯乙烯(PVC)塑料是由氯乙烯单体经自由基聚合而成的聚合物，英文名称polyviny chloride,简称PVC。PVC可分为软PVC和硬PVC。其中硬PVC大约占市场的2/3，软PVC占1/3。软PVC一般用于地板、天花板以及皮革的表层，但由于软PVC中含有柔软剂，容易变脆,不易保存，所以其使用范围受到了局限。硬PVC不含柔软剂，柔韧性好，易成型，不易脆，无毒无污染，保存时间长，因此具有很大的开发应用价值。PVC发泡板具有防腐、防潮、防霉、不吸水、可钻、可锯、可刨、易于热成型、热弯曲加工等特性，因此广泛应用于家具、橱柜、浴柜、展览架用板、箱体芯层、室内外装饰、建材、化工等领域用板,广告标示、印刷、丝印、喷绘、电脑刻字、电子仪表产品包装等行业。PVC硬塑板具有优良的耐腐蚀性、绝缘性，并有一定的机械强度；经二次加工后可制成硫酸(盐酸)槽(桶箱)；医药用空针架，化程架；公共卫生间水箱；加工产品的模板、装饰板、排风管道、设备衬里等各种异型制品、容器。是化工、建材、装饰及其他工业的理想选择材料。
目前市场上有很多PVC共挤板，板面都做得不好，既不光滑细腻、也没有亮度，通常是采用热转印再涂光油或采用PVC面皮用胶水贴面的办法冒充PVC共挤镜面板，含有大量的甲醛等有害物质，气味很大，不利于环保。
