The invention belongs to the technical field of high polymer material composite tarpaulin, and particularly relates to tear-resistant PVC (polyvinyl chloride) composite vehicle tarpaulin, equipment, a preparation method and application. The tarpaulin for the vehicle is composed of base cloth and PVC films attached to the two sides of the base cloth through PVC slurry. Wherein the PVC slurry comprises the following materials: 100 parts of PVC paste resin, 90-120 parts of a plasticizer, 4-8 parts of an adhesive, 11-12 parts of a viscosity reducer and 25-35 parts of PVC calcium powder; the thickness of the PVC slurry permeating into the base cloth is less than or equal to 1/3 of the thickness of the base cloth. Vehicle tarpaulin manufacturing equipment is improved, the bottom film pressing wheel and the surface film pressing wheel are additionally arranged to improve attachment of a PVC film and a large cylinder, an original padding process is changed into a transfer sizing method by means of the modified transfer sizing wheel set, the sizing gram weight and screen cloth permeation can be reduced, and the production efficiency is improved. The tarpaulin tearing performance is improved; and the tarpaulin has good stripping resistance and the like.
本发明属于本发明属于高分子材料复合篷布技术领域,具体涉及一种抗撕裂PVC复合车用篷布及设备、制备方法和用途。该车用篷布,由基布和通过PVC浆料贴合在两侧的PVC薄膜组成。其中PVC浆料包括如下材料:PVC糊树脂100份、增塑剂90~120份、胶黏剂4~8份、降粘剂11~12份和PVC钙粉25~35份;且PVC浆料渗入基布的厚度小于等于基布厚度的1/3。本发明对车用篷布制造设备进行改进,增设了底膜压制轮和面膜压制轮提高PVC薄膜与大缸的贴合,并借助改设的转移上浆轮组将原有浸扎工艺改为转移上浆法,可减少上浆克重和对网布的渗入,增加篷布撕裂性能且具有良好的耐剥离性能等。
