Title (EN) COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
(FR) MATÉRIAU COMPOSITE ET PROCÉDÉ DE PRÉPARATION ASSOCIÉ
(ZH) 一种复合材料及其制备方法
Abstract:
(EN) Disclosed are a porous metal and rubber composite material and a preparation process therefor. A porous metal and rubber containing a solvent or a volatile substance having a certain boiling point are subjected to hot vulcanization molding or radiation curing molding at a certain temperature to obtain a composite material; the composite material is then subjected to baking, vacuum baking or vacuum extraction, and in particular is baked at a temperature higher than the hot vulcanization molding temperature so that the solvent or the volatile substance therein is evaporated or volatilized; and thus, the rubber in the composite material shrinks and the rubber in pores of the porous metal in the composite material collapses. The porous metal in the composite material prepared in the present invention protrudes out of the surface of a conductive composite material, so that the composite material is very suitable for being used as an electrical contact material.
(FR) L'invention concerne un matériau composite à base de caoutchouc et de métal poreux et un procédé de préparation associé. Un métal poreux et un caoutchouc renfermant un solvant ou une substance volatile présentant un certain point d'ébullition sont soumis à un moulage par vulcanisation à chaud ou par durcissement par rayonnement à une certaine température, de manière à obtenir un matériau composite. Le matériau composite est ensuite soumis à une cuisson, une cuisson sous vide ou une extraction sous vide, et est notamment cuit à une température supérieure à la température de moulage par vulcanisation à chaud, de telle sorte que le solvant ou la substance volatile à l'intérieur dudit matériau est évaporé ou volatilisé. Ainsi, le caoutchouc dans le matériau composite rétrécie et le caoutchouc dans les pores du métal poreux dans le matériau composite se replie. Le métal poreux dans le matériau composite de l'invention fait saillie hors de la surface d'un matériau composite conducteur, de telle sorte que le matériau composite est très approprié à une utilisation en tant que matériau de contact électrique.
(ZH) 本发明公开了一种多孔金属和橡胶的复合材料及其制备工艺。通过将多孔金属和含有一定沸点的溶剂或可挥发性物质的橡胶在一定的温度下进行热硫化成型或辐射固化成型,制得一种复合材料,然后将这种复合材料进行烘烤、真空烘烤或真空抽提,特别是在高于热硫化成型温度的温度下进行烘烤,使其中的溶剂或可挥发性物质蒸发或挥发出来,从而使得该复合材料中的橡胶发生收缩,使得复合材料中多孔金属的孔洞中的橡胶发生塌陷。这样制备的复合材料,多孔金属突出于导电复合材料表面,使得这种复合材料很适合于用作电触点材料。
