| 中文摘要: |
| 采用三层共挤吹塑工艺研制轮胎制备用聚乙烯（PE）隔离膜。结果表明：当表层高密度聚乙烯与低密度聚乙烯用量比为1∶1，芯层线形低密度聚乙烯、回收造粒料、隔离剂K用量比为100∶40∶2.5，并在各层中均添加3份遮光及抗紫外线母料，吹胀比为1.45～1.55时，PE隔离膜的透光率较小，对轮胎半成品胶片的隔离和保鲜效果较好。 |
| 英文摘要: |
| The polyethylene （PE） isolation film used in tire production was developed by using three-layer blown film extrusion process.The results showed that， when the ratio of high density polyethylene and low density polyethylene in the surface layer was 1∶1，the ratio of low density polyethylene，recycled granulated materials and agent K in the core layer was 100∶40∶2.5， the addition level of opaque and anti ultraviolet masterbatch in each layer was 3 phr， and the blow-up ratio was 1.45～1.55，the produced PE film had low light transmittance and provided good isolation and preservation effect for semi-finished products of tire. |
