具体实施方式
下面结合具体实施例对本发明作进一步说明：
实施例1：
如图1所示，本实施例所述的一种耐碰撞、抗拉扯且具备防霉、阻燃功能的PVC墙纸，所述PVC墙纸1从下往上分别为无纺布基层2、PET薄膜层3和PVC涂层4的结构，在所述无纺布基层2和PET薄膜层3之间还夹持着底胶层5,使其成为多层结构，其中所述无纺布基层2的原材料选择上也可使用同等强度的各种天然、矿物、合成和人造纤维；所述无纺布基层2与PET薄膜层3通过复合涂布上胶的方式结合，再与所述PVC涂层4通过复合涂布方式结合。
相比传统的PVC墙纸1，其产品结构是由纸底或无纺纸底经过涂布工艺与PVC结合，成型结构单一，导致横向与纵向的拉伸承受力低，其表面受到外力冲击时极易受到损坏。
本申请中的PVC墙纸1由于添加了所述PET薄膜层3作为所述无纺布基层2与PVC涂层4之间的夹层，得到了多层结构的成品，其中添加的所述PET薄膜层3具有优良的耐腐蚀性、耐磨性、出色的绝缘性能、强韧性，抗张强度和抗冲击强度比一般PVC高，结合后制出的成品能达到耐碰撞、抗拉扯且无需添加剂即可具备防霉、阻燃的功能，有效提高产品的耐用性和实用性，产品环保，在实际使用过程中，可具有实用、环保和有效减低损坏的效果。
