preparation example Construction

[0021] In order to solve the problems in the prior art, the current conventional rubber products usually use carbon black materials in the case of permanent antistatic. This material is seriously dyed and will leave black marks on the contacted substances during the contact and friction process. Problem, the present invention provides an antistatic non-fading rubber and its preparation method.

[0022] The invention provides an antistatic and non-fading rubber. The raw material of the rubber includes the following components in parts by weight:

[0023]

[0024] The methyl vinyl silicone rubber selected in the present invention has excellent anti-aging, low-temperature resistance and high-temperature resistance, can be used normally in the range of -60°C to 250°C, and does not produce sulfur-containing substances, and is not harmful to copper-like metal materials. Will produce corrosion phenomenon, can be widely used in the electronics industry.

[0025] In order to adjust...

Embodiment 1

[0039] This embodiment provides an antistatic and non-fading rubber. The raw material of the rubber includes the following components in parts by weight: 100 parts of methyl vinyl silicone rubber, 40 parts of silicon dioxide, 3 parts of methyl silicone oil, 2 parts of 2, 5-Dimethyl-2,5-bis(tert-butylperoxy)hexane, 2 parts of graphene (average particle size is 2nm, specific surface area is 1000m 2 / g).

[0040] This embodiment also provides a preparation method of antistatic and non-fading rubber, comprising the following steps,

[0041] Weigh 100 parts of methyl ethyl silicone rubber, 40 parts of silicon dioxide, 3 parts of methyl silicone oil, 2 parts of 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane , 2 parts of graphene (average particle size is 2nm, specific surface area is 1000m 2 / g) Mix in an open mill so that the components are evenly dispersed, and then vulcanized to obtain antistatic and non-fading rubber.

Embodiment 2

[0043] This embodiment provides an antistatic and non-fading rubber, which is basically the same as in Embodiment 1, except that the raw material of the rubber includes the following components in parts by weight: 100 parts of methyl vinyl silicone rubber, 30 parts of di Silicon oxide, 5 parts of methyl silicone oil, 1 part of 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane, 2 parts of graphene (average particle size is 2nm, specific surface area is 1000m 2 / g).

Abstract

The invention provides antistatic fading-free rubber. The antistatic fading-free rubber is prepared from the following raw material components in parts by weight: 70-120 parts of silicone rubber, 20-40 parts of a filler, 2-5 parts of a processing aid, 1-3 parts of a vulcanizing agent and 0.8-3 parts of an antistatic agent. The antistatic fading-free rubber has stable antistatic performance, does not leave black traces on contact substances, greatly improves the use performance of the product, and is especially suitable for antistatic products which cannot fade or be blackened.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an antistatic and non-fading rubber and a preparation method thereof. Background technique [0002] Rubber has excellent electrical insulation, weather resistance, moisture resistance, shock resistance, pressure resistance and physiological inertia, and can be widely used in various industries. Rubber is generally vulcanized and crosslinked by adding a vulcanizing agent or a vulcanization accelerator. Studies have shown that at present, conventional rubber products usually use carbon black materials in the case of permanent antistatic. Carbon black is an important reinforcing filler in the reinforcing filling system, which is important for the physical and mechanical properties and processing technology of rubber compounds. influences. However, the rubber material with carbon black is seriously dyed, and in the process of contacting and rubbing with substances, it will...
