Abstract

The invention discloses elliptical machine light cover surface silica gel and a preparation method thereof. The light cover surface silica gel comprises, by weight, 100 parts of vinyl polysiloxane, 10-15 parts of white carbon black, 0.15-0.2 part of inhibitors, 0.3-0.5 parts of platinum catalysts, 11-12 parts of hydrogen-containing silicone oil and 0.2-0.5 part of fluoroalkyl silicone oil. By the aid of a compound comprising base gel, the hydrogen-containing silicone oil, propargyl alcohol and methyl propargyl alcohol, the content of vinyl in the base gel is 0.13%, the content of hydrogen in the hydrogen-containing silicone oil is 0.2%, the surfaces of silica gel materials are dried in about 5S at the temperature of about 50 DEG C, operating time is longer than 4H, and the silica gel meets elliptical machine operating requirements. The invention further discloses a preparation method of the elliptical machine light cover surface silica gel. The viscosity of the cover surface silica gel prepared by the method is about ten thousands, defoaming and leveling are the silica gel are accelerated, the silica gel cannot be embrittled, is suitable for elliptical machine operation and good in physical performance and has long operation time, high vulcanization, defoaming and leveling speed.

Description

technical field [0001] The invention relates to the field of screen silica gel printing, in particular to a bright cover silica gel for an elliptical machine and a preparation method of the bright cover silica gel for an elliptical machine. Background technique [0002] Printed silicone is a special liquid silicone that can be firmly adhered to the surface of textiles by screen printing. [0003] In the prior art, the current printing silica gel is generally only suitable for the fingerprint environment, with low work efficiency, high labor cost and low stability of product performance. With the development of mechanization and intelligence, the printing industry urgently needs printing silica gel suitable for printing on elliptical machines. Adopting the method of machine printing, there are some technical problems in the printing silica gel currently on the market. For example, ordinary hand-printed silica gel used for machine-printed cover adhesives has the problem of s...
