Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the examples, but not as any limitation to the present invention.

[0037] A method for preparing silicone rubber compound for rubber clamps. When preparing the silicone rubber compound for rubber clamps, 100 parts by weight of vinyl silicone rubber, 40-65 parts of fumed white carbon black, and 0.2-2 parts of coloring agent are taken. , 2 to 15 parts of vinyl silicone oil, 3 to 10 parts of hydroxy silicone oil, 2 to 8 parts of diphenyl silicon glycol, 0.5 to 1.5 parts of organic peroxide, and 3 to 5 parts of cerium oxide to form the raw materials. After the refinement process is modified, the silicone rubber material for the rubber clamp can be obtained, wherein the colorant can be titanium dioxide or permanent violet R, and the organic peroxide is dicumyl peroxide.

[0038] The modification of the above-mentioned mixing process includes the following steps: mixing the raw material...

Abstract

The invention discloses a preparation method of a silicone rubber material for rubber hoops. The silicone rubber material for rubber hoops is prepared from the following raw materials in parts by weight: 100 parts of vinylsiloxane rubber, 40-65 parts of fumed silica, 0.2-2 parts of coloring agent, 2-15 parts of vinyl silicone oil, 3-10 parts of hydroxy silicone oil, 2-8 parts of diphenyl silanediol, 0.5-1.5 parts of organic peroxide and 3-5 parts of cerium oxide; the silicone rubber material for rubber hoops can be obtained by carrying out mixing process modification treatment on the raw materials. The silicone rubber material for rubber hoops is wide in temperature adaptation range and high in environmental adaptation, can be used for producing various structure type rubber hoops and additionally producing and manufacturing multi-class products, such as sealing parts, shock-absorbing buffer parts, spacers and membranes, and is widely applied to multiple fields of aerospace, nuclear industry, electrommunication, chemical industry, medicine, ships and the like.

Description

technical field [0001] The invention relates to a preparation method of silicone rubber material for rubber clamps, belonging to the technical field of rubber materials. Background technique [0002] With the rapid development of my country's aerospace field in recent years, the demand for various high-performance aerospace equipment is increasing, and its performance requirements are also getting higher and higher, so as to meet the special requirements of different environments. As far as rubber clamp products are concerned, in HB and other standards, the types and quantities of optional rubber materials used to make rubber clamps are limited, and the optional rubber materials have poor environmental adaptability. It cannot meet the requirements for rubber materials in the special environment of the aerospace field. Contents of the invention [0003] The object of the present invention is to provide a method for preparing silicone rubber material for rubber clamps, so a...
