Embodiment 1

[0021] Weigh 100 parts of 107 silicone rubber, 20 parts of dodecyltrimethoxysilane, 5 parts of white carbon black and 0.5 part of di-n-octyltin dilaurate, and add the silicone rubber and dodecyltrimethoxysilane to the machine Stir in a stirring device at 300-600r / min for 1-2min under the protection of argon, then add di-n-octyltin dilaurate and continue stirring for 2-4min, and finally add gas-phase method white carbon black and continue stirring for 4-6min to obtain a binder ; Recycled waste insulating silicone rubber is first crushed, then mixed with a binder at a mass ratio of 4:1 and cured to obtain a rubber material.

Embodiment 2

[0023] The only difference from Example 1 is that the mass ratio of the crushed waste insulating silicone rubber to the binder is 2:1, and the others are the same as Example 1.

Embodiment 3

[0025] The only difference from Example 1 is that the mass ratio of the crushed waste insulating silicone rubber to the binder is 3:1, and the others are the same as Example 1.

Abstract

The invention relates to a rubber material and its application, belonging to the technical field of rubber materials. The rubber material is firstly crushed from waste insulating silicone rubber, then mixed with a binder in a mass ratio of (3-6):1 and cured. The binder includes the following components in parts by weight: 100 parts of 107 silicone rubber, 10-25 parts of dodecyltrimethoxysilane, 3-10 parts of white carbon black and 0.3-25 parts of di-n-octyltin dilaurate 0.6 parts. The invention utilizes an environmentally friendly and non-toxic adhesive to recycle waste composite insulator silicon rubber into a non-polluting and non-toxic rubber mat or rubber track, and meanwhile, has excellent tensile strength and elongation at break.

Description

technical field [0001] The invention relates to a rubber material and its application, belonging to the technical field of rubber materials. Background technique [0002] With polyorganosiloxane as the basic component, white carbon black as the reinforcing filler, aluminum hydroxide and other additives are added to make the rubber compound, and the finished product - composite insulator silicone rubber can be obtained after vulcanization. This product can be widely used in high-voltage transmission lines and is suitable for areas with different pollution levels. It has the characteristics of light weight, small size, unbreakable, high tensile strength, and strong pollution performance. Silicone rubber insulators are mainly used in substations, with good hydrophobicity, aging resistance, tracking resistance and electrical corrosion resistance, high tensile strength and bending strength, high mechanical strength and impact resistance , Shockproof and anti-brittle performance,...
