▎ 摘  要

NOVELTY - Preparing windshield wiper rubber strip, comprises taking high-tear-resistant silicone rubber, fluorine rubber, gas-phase silicone rubber and vulcanizing agent, rolling and kneading to obtain mixed rubber material, spraying rubber material on the inner wall of the strip mold, where rubber material comprises 50-70 pts. wt. hydroxy polyether polyester copolymerized modified polysiloxane, 5-15 pts. wt. molybdenum disulfide, 3-8 pts. wt. graphite, 3-8 pts. wt. graphene and 0.1-5 pts. wt. platinum curing agent, adding mixed rubber material into the rubber strip mold, closing the mold, vulcanizing and cross-linking at 160-180 ℃ for 5-10 minutes to obtain final product. USE - The method is useful for preparing windshield wiper rubber strip. ADVANTAGE - The wiper rubber strip has excellent anti-yellowing performance and anti-tearing property, and provides water repellent film on glass surface, and has excellent leveling property.
