Title (EN) SILICONE RUBBER SPONGE-FORMING EMULSION COMPOSITION AND METHOD FOR MANUFACTURING SILICONE RUBBER SPONGE

Abstract:
(EN) Provided is a silicone rubber sponge-forming emulsion composition for which the emulsion stability does not drop when the amount of reinforcing silica filler is increased, for which the cell shape of a sponge does not become defective, and for which the hardness is not too high; and further provided is a method for manufacturing a silicone rubber sponge from the aforementioned composition. This silicone rubber sponge-forming emulsion composition is comprised of: (A) 100 parts by weight of a liquid diorganopolysiloxane having at least two silicon atom-bonding alkenyl groups within one molecule; (B) 1-50 parts by weight of a reinforcing silica filler comprised of (b1) fumed silica and (b2) precipitation method silica (with the (b1)/(b2) weight ratio being 0.01/1‑30/1); (C) 50-250 parts by weight of water containing (c) smectite clay; (D) 0.1-7 parts by weight of sorbitan fatty acid ester; (E) 0-10 parts by weight of isononanoic acid ester; (F) 0-10 parts by weight of Guerbet alcohol; and (G) an amount of curing agent sufficient to cross-link and harden component (A). This method manufactures a silicone rubber sponge by hardening said composition while heating and dehydrating the same, or by heating and hardening the same and then dehydrating the resulting silicone rubber-like hardened object in the wet state.
(FR) L'invention concerne une composition d'émulsion de formation d'éponge de caoutchouc de silicone présentant : une stabilité d'émulsion qui ne baisse pas lorsque la quantité de la charge de silice de renforcement augmente ; une forme d'alvéoles d'éponge qui ne présente pas de défaut ; et une dureté qui n'est pas trop élevée. L'invention concerne également un procédé de fabrication d'une éponge de caoutchouc de silicone à partir de cette composition. La composition selon l'invention contient : (A) 100 parties en poids d'un diorganopolysiloxane liquide contenant au moins deux groupes alcényle de liaison aux atomes de silicone à l'intérieur d'une molécule ; (B) de 1 à 50 parties en poids d'une charge de silice de renforcement constituée de (b1) silice sublimée et de (b2) silice précipitée (le rapport en poids (b1)/(b2) étant 0,01/1-30/1) ; (C) de 50 à 250 parties en poids d'eau contenant (c) de l'argile smectique ; (D) de 0,1 à 7 parties en poids d'ester d'acide gras de sorbitane ; (E) de 0 à 10 parties en poids d'ester d'acide isononanoïque ; (F) de 0 à 10 parties en poids d'alcool de Guerbet ; et (G) une quantité d'agent vulcanisant suffisante pour réticuler et durcir le composant (A). Le procédé selon l'invention permet de fabriquer une éponge de caoutchouc de silicone par durcissement de cette composition pendant son chauffage et sa déshydratation, ou par chauffage et durcissement de la composition puis déshydratation de l'objet durci de type caoutchouc de silicone résultant à l'état humide.
(JA) 補強性シリカフィラー量を増加しても乳化安定性が低下せず、スポンジのセル形状が不良とならず、硬度がさほど高くならないシリコーンゴムスポンジ形成性エマルション組成物、上記組成物からシリコーンゴムスポンジを製造する方法を提供する。 (A)1分子中に少なくとも2個のケイ素原子結合アルケニル基を有する液状ジオルガノポリシロキサン100重量部、(B)(b1)フュームドシリカと(b2)沈降法シリカ{(b1)/(b2)の重量比が0.01/1~30/1}から成る補強性シリカフィラー1~50重量部、(C)(c)スメクタイトクレーを含有する水50~250重量部、(D)ソルビタン脂肪酸エステル0.1~7重量部、(E)イソノナン酸エステル0~10重量部、(F)ガーベットアルコール0~10重量部、および(G)成分(A)を架橋し硬化させるに充分な量の硬化剤からなる、シリコーンゴムスポンジ形成性エマルション組成物。該組成物を、加熱して脱水しつつ硬化せしめる、または、加熱して硬化せしめ,次いで生成した湿潤状態のシリコーンゴム様硬化物を脱水することによる、シリコーンゴムスポンジの製造方法。
