Conductive silica gel and preparation method thereof

Abstract

The invention belongs to the field of rubber, and specifically relates to conductive silica gel and a preparation method thereof. The conductive silica gel is prepared from the following raw materials in parts by weight: 20 to 30 parts of methyl vinyl phenyl silicone rubber, 20 to 35 parts of natural rubber, 17 to 22 parts of vinyl silicone oil, 65 to 70 parts of fumed silica, 12 to 18 parts of decamethyl cyclopentasiloxane, 12 to 17 parts of C5 petroleum resin, 12 to 15 parts of silicon dioxide, 40 to 50 parts of a conductive material, 20 to 30 parts of deionized water, 0.4 to 1 part of a coupling agent and 0.0003 to 0.0006 part of a catalyst. According to the conductive silica gel and the preparation method thereof, provided by the invention, a substrate with better comprehensive performance is obtained through mixing of the natural rubber and silicone rubber, so that the conductive silica gel can be prevented from being stolen or the conductivity can be prevented from being affected by grease corrosion, and the service life of the rubber is prolonged; through cross linking on the C5 petroleum resin, the silicon dioxide and the like, the smoothness of a material is increased, not only is the human body contact comfort good, but also the surface is smooth, and washing is easy.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to a conductive silica gel and a preparation method thereof. Background technique [0002] Massage health care equipment or massage underwear using the principle of radio waves, the part of the massage piece in contact with the human body uses conductive silica gel, which is used for human body contact for massage and current transmission. Since conductive rubber often contacts human skin, there will be sweat and grease. , has an impact on the properties of silica gel, accelerates the aging of conductive rubber, and the conductive silica gel on the surface of the massage sheet is sticky and difficult to clean. Contents of the invention [0003] In view of the above technical problems, the present invention provides a conductive silica gel with an easy-to-clean surface. [0004] The specific technical solutions are: [0005] A conductive silica gel, made of the following raw mat...
