The invention belongs to the technical field of plastic films, and discloses a single-layer straight-out PVC matte film and a preparation method thereof. The PVC matte film is prepared from the following raw material components: polyvinyl chloride resin, a plasticizer and a flexibilizer, wherein the flexibilizer comprises a polyethylene chlorinated elastomer. The special raw material components are selected, so that the PVC matte film can be directly prepared through a casting extrusion process, and the PVC matte film has the advantages of favorable weather resistance, low yellowing tendency and favorable matte property, omits the back coating and laminating processes, can greatly simplify the preparation process, and obviously reduces the defects of landscape lines, flow lines and the like.

    本发明属于塑料薄膜技术领域,公开了一种单层直出的PVC哑光膜及其制备方法。制备该PVC哑光膜的原料组分包括:聚氯乙烯树脂、塑化剂、增韧剂,所述增韧剂包括聚乙烯氯化弹性体。本发明由于选择特殊的原料组分,故本发明可直接通过流延挤出工艺即可制得PVC哑光膜,具有良好的耐候性,不易变黄,且哑光性好,省去背涂和贴合工艺,可大大简化制备过程,显著减少山水纹,流纹等缺陷的存在。
