Description

一种PVC地板革
技术领域
本发明涉及建筑材料技术领域，特别涉及一种PVC地板革。
背景技术
地板革(又称卷材地板)，一种新型的铺地材料，属于塑料制品，是现代居室装饰不可或缺的地面材料之一，厚度1.5毫米以上，耐磨层0.1以上，一般采用平整度好的玻璃丝或双涂底。塑料地板革属于软质地板，是以聚氯乙烯树脂为主要原料，加入适当助剂，在片状连续基材上经涂敷或压延等工艺生产的地板卷材。
现在的塑料地板革在原料中添加阻燃剂，一方面由于添加阻燃剂将带来成本的上升，又很难为材料制造商带来经济方面的效益，另一方面，地板革添加阻燃剂后虽然有较高的阻燃性能，但在燃烧时烟雾量大，并且释放出来的气体具有高度腐蚀性，往往发生二次污染。
发明内容
本发明提供一种PVC地板革，解决现有的PVC地板革由于添加阻燃剂带来生产成本的上升和二次污染的问题。
为解决上述技术问题，本发明的技术方案为：
一种PVC地板革，按重量份数计是由以下组分制成的：PVC糊80～100重量份、增塑剂30～50重量份、蜜胺树脂泡沫粉20～25重量份、热稳定剂0.02～0.08重量份、着色剂0.006～0.009重量份、润滑剂3～8重量份。
其中，优选地，所述蜜胺树脂泡棉粉是将废蜜胺树脂泡绵用粉碎机粉碎，使其粒度≤100目。
其中，优选地，所述蜜胺树脂泡绵是采用下述制备方法制成：
(1)取三聚氰胺和多聚甲醛，混合均匀；
(2)混合物料由物料泵输入第一螺杆机，在第一螺杆机进料口处加入碱液，使内部物料的pH值在8～10之间，反应体系在输送混合过程中进行反应，反应时间为5～10min，反应温度为80～160℃；
(3)在第一螺杆机进料端、中间位置或末端加入辅料溶液；
(4)从第一螺杆机出口挤出的透明树脂进入第二螺杆机，在第二螺杆机内继续进行聚合反应，反应时间为25～45min，反应温度为65～95℃，生成蜜胺树脂；
(5)从第二螺杆机尾部出来的透明树脂经过降温装置后进入第三螺杆机，第三螺杆机采用循环冷却水进行冷却，第三螺杆机的出料温度为30～40℃；
(6)将发泡剂、乳化剂、稳定剂和固化剂从第三螺杆机中部通入，与树脂混合均匀；
(7)将混合均匀的树脂通入微波发泡炉内发泡，形成高开孔率的蜜胺树脂泡沫海绵；
(8)链板将蜜胺树脂泡沫海绵从微波发泡炉中输送到喷淋腔体中，喷淋腔体的顶部设置有喷淋头，喷淋头将质量百分比浓度为0.1～0.3％的氨水或氯化铵溶液对泡沫进行喷淋，喷淋液与泡绵中的游离甲醛发生化学反应，去除蜜胺树脂泡沫海绵中残留的甲醛；
(9)将泡绵输送到微波烘干箱中，烘干，得蜜胺树脂泡绵。
其中，优选地，所述热稳定剂为硬脂酸锌、硬脂酸钡和硬脂酸镉中的任意一种或几种。
其中，优选地，所述增塑剂为DOP或环氧大豆油。
其中，优选地，所述润滑剂为氯化石蜡。
本发明的有益效果：
本发明在PVC地板革中添加蜜胺树脂泡沫粉，由于蜜胺树脂泡沫具有良好的阻燃性能，在PVC地板革添加蜜胺树脂泡沫粉一方面具有阻燃性能，使PVC地板革阻燃等级达到A级，且和现有的PVC地板革相比，燃烧时释放的有害气体大大的降低。
另外，蜜胺树脂泡沫粉具有还具有填充剂的作用，使地板革重量变轻，并且回弹性、柔软性也进一步提高。
