Title (EN) MODIFIED NANOCOMPOSITE SILICONE RUBBER SEAL RING AND PREPARATION THEREOF
(FR) JOINT D'ÉTANCHÉITÉ EN CAOUTCHOUC DE SILICONE NANOCOMPOSITE MODIFIÉ ET SA PRÉPARATION
(ZH) 改性纳米复合硅胶密封圈及其制备
Abstract:
(EN) Provided is a modified nanocomposite silicone rubber seal ring, comprising: raw rubber mixing rubber material and vulcanizing agent with weight ratio of 100: 0.5 to 10. The raw rubber mixing rubber material comprises the following parts by weight: 70 to 100 parts of methyl vinyl silicone rubber, 1 to 20 parts of plasticizer, 0.01 to 10 parts of modified nano additive, 10 to 50 parts of reinforcing filler and 0.5 to 5 parts of coupling agent. The modified nano additive is one of modified white graphene, modified graphene and graphene oxide. The composite silicone rubber seal ring is added with a small amount of nano-modified particles, which is helpful in increasing sealing performance and mechanical strength, while not affecting other properties. The modified nanocomposite silicone rubber seal ring effectively solves the problems that water vapor and gas permeability of the silicone seal ring is degraded and mechanical properties thereof is reduced due to the aging in the course of a long time using, thereby greatly extending the service life of the sealing material.
(FR) L'invention concerne un joint d'étanchéité en caoutchouc de silicone nanocomposite modifié comprenant : un matériau de caoutchouc de mélange de caoutchouc brut et un agent de vulcanisation selon un rapport pondéral de 100:0,5 à 10. Le matériau de caoutchouc de mélange de caoutchouc brut comprend les parties suivantes en poids : 70 à 100 parties d'un caoutchouc de silicone méthylique de vinyle, 1 à 20 parties d'un plastifiant, 0,01 à 10 parties d'un nano-additif modifié, 10 à 50 parties d'une charge de renforcement et 0,5 à 5 parties d'un agent de couplage. Le nano-additif modifié est un graphène blanc modifié, un graphène modifié et un oxyde de graphène. Le joint d'étanchéité en caoutchouc de silicone composite est complété d'une petite quantité de particules nano-modifiées, ce qui permet d'augmenter les performances d'étanchéité et la résistance mécanique, sans affecter les autres propriétés du joint. Le joint d'étanchéité en caoutchouc de silicone nanocomposite modifié selon l'invention résout efficacement les problèmes de dégradation due à la perméabilité du joint à la vapeur d'eau et aux gaz, et la réduction des propriétés mécaniques due au vieillissement du joint sur une longue durée d'utilisation, ce qui prolonge considérablement la durée de vie du matériau d'étanchéité.
(ZH) 一种改性纳米复合硅胶密封圈,包括:重量比为100:0.5~10的生胶混炼胶料和硫化剂;所述生胶混炼胶料包括重量份数为:70~100份甲基乙烯基硅橡胶,1-20份增塑剂,0.01~10份改性纳米添加剂,10~50份补强填料,0.5~5份偶联剂;所述的改性纳米添加剂为改性白石墨烯、改性石墨烯、氧化石墨烯中的一种。复合硅胶密封圈少量添加纳米改性微粒,有利于增加密封性能和机械强度,而其他性能则不受影响。有效改善了硅胶密封圈在长时间使用过程中出现老化导致的水蒸汽、气体透过性变差和机械性能的降低,大大延长了密封材料使用寿命。
