本申请涉及塑胶材料领域,具体公开了一种用于共挤、流延工艺的修复层粒子及其制备方法和车衣。一种用于共挤、流延工艺的修复层粒子,由包括如下重量份的原料制成:多元醇44~46份、多异氰酸酯35~36.8份、羟基丙烯酸树脂0.04~0.13份、扩链剂0.8~1.3份、助剂0.91~0.95份;修复层粒子可用于与TPU母料共同挤出,得到表面附有修复层的车衣。本申请中使用修复层粒子代替传统制备工艺中的修复剂,所得修复层对车衣基材层的防护效果更优,还能简化车衣的制备工艺,使得车衣的制备工艺绿色环保。

    The invention relates to the field of plastic materials, and particularly discloses repair layer particles for co-extrusion and tape casting processes, a preparation method of the repair layer particles and a car cover. The invention relates to a repairing layer particle for a co-extrusion and tape casting process. The repairing layer particle is prepared from the following raw materials in parts by weight: 44 to 46 parts of polyhydric alcohol, 35 to 36.8 parts of polyisocyanate, 0.04 to 0.13 part of hydroxy acrylic resin, 0.8 to 1.3 parts of chain extender and 0.91 to 0.95 part of assistant, the repair layer particles can be used for co-extrusion with TPU master batch to obtain the car cover with the repair layer attached to the surface. The repair layer particles are used for replacing a repair agent in a traditional preparation process, the protection effect of the obtained repair layer on the vehicle cover base material layer is better, the preparation process of the vehicle cover can be simplified, and the preparation process of the vehicle cover is green and environmentally friendly.
