Abstract
A thread made from extruded silicone rubber that is cross-linked after the extrusion and woven into a fabric having warp threads and/or weft threads and a coating including cross-linked silicone rubber, the thread or the coating including a fluorinated rubber portion. The invention also relates to a method for producing such threads and woven fabrics. The object of the invention is to improve thermal and chemical resistance. To this end the fluorinated rubber part is produced only by surface fluorination of the cross-linked thread or the coating by means of a fluorinated gas.
Claims16
A method for producing a press pad, the method comprising the steps:
- providing an elastomeric material matrix that is resistant to temperatures above 200 degrees C. and that includes an additive that increases heat conductivity;
- producing a thread from the elastomeric material matrix;
- producing a fabric with warp threads and weft threads from the thread;
- producing the press pad from the fabric,
- wherein the additive is dispersed in an organically modified siloxane and worked into the elastomeric material matrix together with the organically modified siloxane, and
- wherein the organically modified siloxane is organically modified polysiloxane with organic polymers on an acrylate base that are arranged along the chain with 30% by weight hexagonal boron nitride and 5% by weight multiwall carbon nanotubes dispersed therein.
A method for producing a press pad, the method comprising the steps:
- coating an elastomeric material matrix that is resistant to temperatures above 200 degrees C. and that includes an additive that increases heat conductivity onto a fabric that includes warp threads weft threads;
- and
- crosslinking the high temperature resistant elastomeric material matrix after the coating,
- wherein the additive is dispersed in an organically modified siloxane and worked into the high temperature resistant elastomeric material matrix together with the organically modified siloxane, and
- wherein the organically modified siloxane is organically modified polysiloxane with organic polymers on an acrylate base that are arranged along the chain with 30% by weight hexagonal boron nitride and 5% by weight multiwall carbon nanotubes dispersed therein.
