| abstract |
The invention discloses a low water vapor permeability polyolefin elastomer adhesive film and a preparation method, which comprise 50-100 parts by mass of a matrix resin, 0-40 parts by mass of a modified resin, and 0.001-2 parts by mass of an active agent , 0.1-3 parts by mass of organic peroxide, 0.02-5 parts by mass of co-crosslinking agent, 0.02-2 parts by mass of silane coupling agent, 0.005-2 parts by mass of light stabilizer, 0-20 parts by mass of Water blocking filler. The present invention improves the crosslinking degree and crosslinking density of the film by adding modified resin and activator with active groups, and reduces the water vapor transmission rate; adding water-blocking fillers further improves the water-blocking performance of the film, ensuring that Component reliability, extending component life. |
