高倍率PVC涂层发泡材料生产工艺

Production Process of High-rate PVC-Coated Foaming Material

聚氯乙烯(PVC)涂层发泡材料对配方、发泡过程中的温度、烘箱风量等要求很高,工艺比较复杂,目前国内还没有厂家可以生产出厚度5mm以上的PVC涂层发泡材料。通过对发泡原理、PVC涂层发泡材料的糊剂配方、涂层生产工艺以及成品运用领域等进行探索研究,制备高倍率(6~8倍)PVC涂层材料,填补该行业高端产品方面的生产空缺。

The preparation process of polyvinyl chloride (PVC) coated foaming materials is quite complicated, it has high requirements on formula, foaming temperature, and oven air volume. At present, there is no domestic manufacturer that can produce PVC-coated foaming materials with thickness of more than 5 mm. Through exploring and studying the foaming principle, paste formula of PVC -coated foaming material, coating process and application field of finished products, the PVC-coated foaming material with high foaming ratio (6 to 8 times) was prepared to fill the gap of top products in this industry.
