Abstract:
(EN) The present invention relates to the technical field of materials, and particularly discloses a composite silicone sealant having a high gas barrier property, comprising a component A and a component B. The component A comprises, in parts by mass, 100 parts of a base rubber, 0.01-10 parts of a nanometer material powder, 40-100 parts of a filler and 5-10 parts of a silane coupling agent. The component B comprises, in parts by mass, 10-20 parts of a crosslinking agent, 10-30 parts of a plasticizer and 0.1-2 parts of a catalyst. The weight ratio of the component A to the component B is 10-13 : 1. The nanometer material powder comprises 5-10 layers of one of a graphene oxide, a modified graphene or a modified white graphene. In the present invention, the barrier property and mechanical strength of the silicone sealant can be greatly improved by adding 5-10 layers of a graphene oxide, a modified graphene or a modified white graphene in a small amount, without affecting other properties. The silicone sealant of the present invention is used for secondary sealing of hollow glasses, has good compatibility with butyl rubber used in primary sealing, has good processability and is environmentally friendly.
(FR) La présente invention concerne le domaine technique des matériaux, et en particulier un matériau d'étanchéité en silicone composite ayant une propriété élevée de barrière aux gaz, comprenant un composant A et un composant B. Le composant A comprend, en parties en masse, 100 parties d'un caoutchouc de base, 0,01 à 10 parties d'une poudre d'un matériau de l'ordre du nanomètre, 40 à 100 parties d'une charge et 5 à 10 parties d'un agent de couplage au silane. Le composant B comprend, en parties en masse, 10 à 20 parties d'un agent de réticulation, 10 à 30 parties d'un plastifiant, et 0,1 à 2 parties d'un catalyseur. Le rapport en poids du composant A sur le composant B, à savoir A/B, est de 10 à 13:1. La poudre de matériau de l'ordre du nanomètre comprend de 5 à 10 couches d'un oxyde de graphène, d'un graphène modifié ou d'un graphène blanc modifié. Dans la présente invention, la propriété de barrière et la résistance mécanique du matériau d'étanchéité à base de silicone peuvent être considérablement améliorées par l'ajout de 5 à 10 couches d'un oxyde de graphène, d'un graphène modifié ou d'un graphène blanc modifié en petite quantité, sans affecter les autres propriétés. Le matériau d'étanchéité à base de silicone de la présente invention est utilisé pour l'étanchéité secondaire de verres creux, il présente une bonne compatibilité avec le caoutchouc butyle utilisé dans l'étanchéité primaire, a une bonne aptitude au traitement et est respectueux de l'environnement.
