  • Method for preparing a silica suspension in an potentially crosslinkable silicone material
    申请人:Chaussade Marc
    公开号:US20060241222A1
    公开(公告)日:2006-10-26
    The invention concerns a method for preparing a precipitated silica suspension in a silicone oil, said suspension being useable for producing silicones crosslinkable by polyaddition, polycondensation or condensation by dehydrogenation (elastomers). The invention aims at solving the problem of finding a compromise between cost, rheology and mechanical properties of the final elastomers. Therefore, the invention provides a method for preparing a precipitated silica suspension treated with trimethylchlorosilane, in the presence of hexamethyldisiloxane, in a crosslinkable silicone oil. HCl can be used. Grafting of the hydrophobic units on the silica and incorporation of the polyorganosiloxane silicone material are carried out during one single processing sequence, without passing through the powder form for the silica. Sodium silicate promoting MQ resin can be incorporated in the reaction medium. The invention also concerns the preparation of a crosslinkable silicone elastomer composition from said suspension, and the resulting composition.
    本发明涉及一种在硅油中制备沉淀二氧化硅悬浮液的方法,该悬浮液可用于生产通过聚加、聚缩或脱氢缩合(弹性体)交联的硅烷。本发明旨在解决在最终弹性体的成本、流变学和机械性能之间找到平衡的问题。因此,本发明提供了一种在可交联的硅油中处理了三甲基氯硅烷的沉淀二氧化硅悬浮液的制备方法,在六甲基二硅氧烷的存在下进行。可以使用HCl。在一次处理序列中进行硅胶上的疏水基的接枝和聚有机硅氧烷硅材料的纳入,而无需通过硅胶的粉末形式。可以在反应介质中加入促进MQ树脂的硅酸钠。本发明还涉及从该悬浮液中制备可交联的硅烷弹性体组合物以及所得到的组合物。
  • CROSSLINKABLE LIQUID SILICONE COMPOSITION COMPRISING A NOT VERY VISCOSIFYING FILLER BASED ON ZIRCONIUM, USE OF SAME AS FIRE-RESISTANT TEXTILE COATING
    申请人:DESNE Francois
    公开号:US20090022895A1
    公开(公告)日:2009-01-22
    The invention concerns crosslinkable liquid silicone compositions whereof the inorganic filler can be increased while observing limits of viscosity compatible with coating of woven or nonwoven supports on an industrial scale, and which impart to the supports thermal properties (reducing calorific power and fire-proofing), impermeability and good mechanical characteristics. To achieve this, a mineral compound is used based on zirconium (zirconia or zirconium silicate) as filler slightly thickening ChZr in a crosslinkable liquid silicone composition. The ChZr has a D; ranging between 3 and 15 m and is used in a proportion of 100 to 350 parts by weight for 100 parts by weight of the silicone composition without fillers. Said silicone compositions may be of the type crosslinkable by polyaddition or polycondensation. The invention is useful for silicone coating textile tarpaulins for indoor or outdoor structures.
    本发明涉及可交联的液态硅橡胶组合物,其中无机填料可以增加,同时观察到与织物或非织造支撑材料的涂覆相兼容的粘度限制,并赋予支撑材料热性能(降低发热功率和防火性能)、不透水性和良好的机械特性。为实现这一目的,使用基于锆的矿物化合物(氧化锆或二氧化锆硅酸盐)作为填料,略微增稠可交联液态硅橡胶组合物中的ChZr。ChZr的D值在3至15m之间,并以100至350重量份的比例用于100重量份的不含填料的硅橡胶组合物。所述硅橡胶组合物可以是通过聚加或聚缩交联的类型。本发明适用于用于室内或室外结构的硅橡胶涂层纺织篷布。

    The invention concerns a method for preparing a precipitated silica in a silicone oil, said suspension being useable for producing silicones crosslinkable by polyaddition, polycondensation or condensation by dehydrogenation (elastomers). The invention aims at solving the problem of finding a compromise between cost, rheology and mechanical properties of the final elastomers. Therefor, the invention provides a method for preparing a precipitated silica suspension treated with trimethylchlorosilane, in the presence of hexamethyldisiloxane, in a crosslinkable silicone oil. HCl can be used. Grafting of hydrophobic units on the silica and incorporation of the polyorganosiloxane silicone material are carried out during one single processing sequence, without passing through the powder form for the silica. Sodium silicate promoting MQ resin can be incorporated in the reaction medium. One of the characteristics of the inventive method is that it does not at all comprise a step involving dried hydrophobic silica. The invention also concerns the preparation of crosslinkable silicone elastomer composition from said suspension, and the resulting composition.
    本发明涉及一种在硅油中制备沉淀二氧化硅的方法,该悬浮液可用于生产可通过聚加成链、聚缩成链或脱氢缩合(弹性体)交联的硅烷。本发明旨在解决在最终弹性体的成本、流变学和机械性能之间寻找折衷方案的问题。因此,本发明提供了一种在可交联硅油中处理三甲基氯硅烷的沉淀二氧化硅悬浮液的制备方法,在六甲基二硅氧烷的存在下进行。可以使用HCl。在一次处理序列中,在不经过硅烷粉末的情况下,对硅烷进行了疏水基的嫁接和聚有机硅烷硅材料的纳入。可以在反应介质中加入促进MQ树脂的硅酸钠。本发明的一个特点是根本不包括涉及干燥的疏水性二氧化硅的步骤。本发明还涉及从所述悬浮液中制备可交联硅弹性体组合物及所得组合物的制备。
