Description

PVC塑胶地板冷却定型方法
技术领域
本发明涉及PVC塑胶地板冷却技术，属于PVC塑胶生产领域，具体是一种PVC塑胶地板冷却定型方法。
背景技术
高温直拉的塑胶地板，因为本身的高温无法散去，卷取后极易收缩变形，从而导致产品两边翘起，薄厚不均匀等问题，一般的冷却技术直接一次水冷，对塑胶地板的结构会产生破坏，使得产品的质量下滑，为了提高塑胶地板的稳定性，解决产品热收缩问题，提高产品的平整度，是亟待解决的问题。
发明内容
本发明的目的在于提供一种PVC塑胶地板冷却定型方法。
本发明的目的可以通过以下技术方案实现：
PVC塑胶地板冷却定型方法，所述PVC塑胶地板冷却定型方法包括以下三个步骤：
a、由摸头挤出的覆膜成形高温塑胶地板，先进入10-15℃水池中进行初次降温，水池温度经过高温塑胶地板达到50-60℃时，进入下一道化学降温工序；
b、将步骤“a”中50-60℃的塑胶地板，流入5-10℃的冷却材料T1中，进行二次冷切，冷切至温度在30-40℃时取出塑胶地板；
c、将步骤“b”中30-40℃的塑胶地板，再次流经10-15℃水池中进行清洗及降温，清洗时间在20-25分钟，降温后温度控制在15-20℃，取出塑胶地板；
所述冷却材料T1包括氧化钙5-15kg、四氧化三铁3-11kg、二氧化钛8-13kg、机油8-19kg、铅粉2-6kg、氧化钡12-15kg、硫酸铜11-16kg、硅烷偶联剂7-12kg、乙醇3-8kg、乙烯2-12kg和聚氨酯9-12kg。
本发明的有益效果：本发明提供一种科学的塑胶地板三次分段冷却技术，提高了塑胶地板的稳定性，解决产品热收缩问题，提高了产品的平整度。
