一种低水汽透过率聚烯烃弹性体胶膜及制备方法
摘要：
本发明公开了一种低水汽透过率聚烯烃弹性体胶膜及制备方法，它包括50～100质量份的基体树脂、0～40质量份的改性树脂、0.001～2质量份的活性剂、0.1～3质量份的有机过氧化物、0.02～5质量份的助交联剂、0.02～2质量份的硅烷偶联剂、0.005～2质量份的光稳定剂、0～20质量份的阻水填料。本发明通过加入带有活性基团的改性树脂和活化剂，提高了胶膜的交联度和交联密度，降低了水汽透过率；加入阻水填料进一步提高胶膜阻水性能，保证组件可靠性，延长组件寿命。
摘要（英）：

The invention discloses a polyolefin elastomer rubber film with low water vapor permeability and a preparation method thereof. The rubber film comprises 50-100 parts by mass of matrix resin, 0-40 parts by mass of modified resin, 0.001-2 parts by mass of an active agent, 0.1-3 parts by mass of organic peroxide, 0.02-5 by mass parts of an assistant cross-linking agent, 0.02-2 parts by mass of a silane coupling agent, 0.005-2 parts by mass of a light stabilizer and 0-20 parts by mass of water-blocking filler. According to the invention, the modified resin and activating agent with active groups are added, so that the cross-linking degree and crosslinking density of the rubber film are improved, and the water vapor transmission rate is reduced; and the water-blocking filler is added, so that water-blocking performance of the rubber film is further improved, reliability of assemblies is ensured, and the service life of the assemblies is prolonged.
