Article and method for producing an article with a silicone-type base material and solid material particles introduced into a surface of the article

摘要

A silicone article, such as a cable with a silicone outer jacket. Solid mica particles are introduced into the surface of the cable or other article. An intermediate product which has a silicone-type base material on the exterior is initially provided in a state that is not, or no more than partially, cross-linked. The solid material particles are subsequently pressed in, before the complete cross-linking takes place. The solid material particles are present only in the surface region.

1. A method of producing an article with an exterior surface of a silicone-type material, the method comprising:
in a first step, fashioning an at least partially non-cross-linked base material into an intermediate product; subsequently, in a second step, introducing solid mica particles into the surface by guiding the at least partially non-cross-linked intermediate product through a reservoir containing the solid mica particles therein, and exposing the reservoir to vibration or generating in the reservoir a vortex or an airstream to thereby mechanically press the solid mica particles into the surface and to cause the particles to be distributed over the surface, with a dot-shaped contact zone formed in each case, and wherein at least some of the solid mica particles project out of the surface as scales; and subsequently, in a third step, cross-linking the at least partially non-cross-linked base material.
