Abstract

The invention discloses pressing bottoming silica gel for an elliptical machine. The pressing bottoming silica gel is prepared from the following raw materials in parts by mass: 100 parts of vinyl polysiloxane, 10-15 parts of white carbon black, 0.15-0.2 part of inhibitor, 5-10 parts of polyvinylsilicone oil, 35-45 parts of cellulose, 2-3 parts of hexamethyl disilazane, 0.3-0.5 part of platinum catalyst, 10-11 parts of hydrogen-containing silicone oil and 30-40 parts of No. 120 solvent oil. The invention also discloses a preparation method of the pressing bottoming silica gel for the elliptical machine. According to the pressing bottoming silica gel for the elliptical machine disclosed by the invention, by adopting a composition of base gel containing 0.13% of vinyl, 0.2% of the hydrogen-containing silicone oil, propyl butynol and methyl butynol, sizing materials of the silica gel are surface-dried at about 50 DEG C for about 5S, the operation time is longer than 4h, and the operation needs of the elliptical machine are met. By adopting the vinyl polysiloxane with appropriate viscosity, the white carbon black of a proper proportion and the No. 120 solvent oil of a proper proportion, the finally prepared bottoming silica gel with viscosity about 300,000 is suitable for operation on the elliptical machine.

Description

technical field [0001] The invention relates to the field of screen silica gel printing, in particular to a pressurized base silica gel for an elliptical machine and a method for preparing the pressurized base 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 after screen printing. [0003] The current printing silicone is generally only suitable for the handprint 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. Adopt the method of machine printing, the products on the market currently have some technical problems. For example, ordinary handprint embossed backing silica gel is used for machine printing embossed backing silica gel, which has problems such...
