    • The invention relates to the adhesive bonding of fibrous materials, in particular of flexible supports, such as woven supports or nonwoven supports, comprising at least one silicone coating obtained by the application of a coat or by impregnation. The aim of the invention is to provide an improved process for combining together fiber/silicone composite parts using a silicone elastomer, which process has to be economical and not very expensive to carry out. This aim is achieved by the invention, which relates to a process for the adhesive bonding of fibrous supports, this process being of the type of those consisting in causing the supports to be adhesively bonded to overlap one another, a silicone-based adhesive thermosetting by radical crosslinking using at least one peroxide being inserted between the supports over at least a portion of the region of overlap. The process is characterized in that it consists essentially in employing at least one silicone adhesive selected from Pumpable Silicone Elastomers (PSE) or Liquid Silicone Rubbers (LSR): e.g. MDDViM, comprising as filler silica treated with a silicone MOHDMOH, which are thermosetting by radical crosslinking using at least one peroxide, which are liquid at ambient temperature and which have a Brookfield viscosity η at 25° C.≧100 Pa·s and an extrusion rate Er in g.min−1≦−50; in directly forming and deploying this liquid adhesive on at least one of the supports to be adhesively bonded in their region of overlap; in holding the supports in intimate contact in their region of overlap comprising at least one layer of adhesive, so as to prevent any trapping of air at the interface; and in heating the supports thus held in intimate contact, so as to make possible the adhesive bonding of the supports by crosslinking of the adhesive.
    • 本发明涉及纤维材料的粘合剂,特别是柔性载体,例如纺织支撑体或非织造支撑物,其包括通过涂覆或浸渍获得的至少一种硅氧烷涂层。 本发明的目的是提供一种使用硅氧烷弹性体将纤维/硅酮复合部件组合在一起的改进方法,该方法必须是经济的并且不是非常昂贵的。 该目的通过本发明来实现,本发明涉及一种用于纤维支撑体的粘合剂的方法,该方法是这样一种方法,其包括使支撑体粘合地彼此重叠的那些类型,由硅基粘合剂热固化的硅氧烷基粘合剂 自由基交联使用至少一种过氧化物在重叠区域的至少一部分上插入支撑体之间。 该方法的特征在于其基本上使用至少一种选自可泵送硅酮弹性体(PSE)或液体硅橡胶(LSR)的硅氧烷粘合剂: M D D M M,其包含用硅氧烷M OH(OH)OH处理的填料二氧化硅,其通过使用至少一种过氧化物的自由基交联进行热固化, 其在环境温度下是液体的,并且其在25℃下具有Brookfield粘度等级> = 100Pa.s,挤出速率Er(g.min)≤50; 在至少一个支撑体上直接形成和展开该液体粘合剂以在其重叠区域中粘合地结合; 在其包括至少一层粘合剂的重叠区域中保持紧密接触的支撑件,以防止在界面处的任何空气捕获; 并且加热由此保持紧密接触的支撑件,从而可以通过粘合剂的交联使支撑体粘合。

    • A process for increasing the surface tension (“wettability”) of a silicone element crosslinked by polyaddition from a liquid composition containing one or more α,ω-dimethylvinylpolydimethylsiloxanes (PDMS), one or more poly(dimethyl)(methylhydrogenosiloxy)-α,ω-dimethylhydrogenosiloxanes, and a platinum crosslinking catalyst. The silicone surface is treated with a homogeneous atmospheric plasma using a plasma spraying apparatus having a rotating head with one or more plasma nozzles that are offset relative to the axis of rotation, each one being capable of generating a plasma jet whose axis is parallel to said axis of rotation. The articles to which the invention relate include composites of flexible substrate (e.g. textile)/silicone coating. Application: adhesive bonding of silicone surfaces crosslinked by ≡Si—H/≡Si-vinyl polyaddition.
