The invention discloses a base material film for a car cover, a preparation method of the base material film and the car cover. The base material film for the car cover is prepared from the following raw materials in parts by weight: 100 parts of polyolefin elastomer, 1-60 parts of olefin polymer containing double bonds, 0-50 parts of ionized monomer and 0.1-10 parts of auxiliaries, the polyolefin elastomer is EVA resin and/or POE resin. The preparation method comprises the following steps: blending a polyolefin elastomer and an olefin polymer containing double bonds, and carrying out film drawing treatment and crosslinking treatment to obtain the base material film for the car cover. The base material film for the car cover has excellent tensile strength and elongation at break, is excellent in weather resistance, and can replace a TPU material car cover in use performance; and meanwhile, the raw materials are low in price, so that the production cost is far lower than that of a TPU (thermoplastic polyurethane) automobile cover, and the automobile cover has a better development prospect.

    本申请公开了一种车衣用基材膜及其制备方法和车衣。一种车衣用基材膜,按重量份计,包括如下原料:聚烯烃弹性体100份、含双键的烯烃类聚合物1‑60份、离子化单体0‑50份、助剂0.1‑10份;所述聚烯烃弹性体为EVA树脂和/或POE树脂。聚烯烃弹性体与含双键的烯烃类聚合物共混,再经过拉膜处理和交联处理制得车衣用基材膜;车衣用基材膜具有优异的拉伸强度和断裂伸长率,且耐候性能优异,能够在使用性能上代替TPU材质车衣;同时由于原料的价格低廉,其生产成本远低于TPU材质车衣,具有较好的发展前景。
