Abstract

The invention discloses a wear-resisting elevator belt rubber material containing silicon. The wear-resisting elevator belt rubber material is characterized by comprising the following raw materials in percentage by weight: 25-35 parts of reinforced silicone rubber, 25-35 parts of styrene-butadiene rubber, 4-7 parts of zinc oxide, 5-8 parts of stearic acid, 0.6-0.8 part of an accelerant TMTD, 0.4-0.6 part of silicon dioxide hydrate, 0.3-0.5 part of an anti-aging agent, 2-4 parts of sulphur, 5-8 parts of acetylene black, 3-5 parts of pottery clay powder, 1-3 parts of salicylanilide, 0.7-0.9 part of bi-(3-triethoxypropyl-silane)-tetrasulfide, 0.8-1 part of a dispersing agent, 0.4-0.6 part of tetramethyl thiuram monosulfide and 0.4-0.6 part of an assistant. The obtained elevator belt rubber material has excellent heat resistance, heat-aging resistance, stretch resistance and wear-resisting property.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a silicon-containing wear-resistant lifting belt rubber material. Background technique [0002] Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance. The outstanding performance of silicone rubber is that it can be used in a wide temperature range, which can be used at -60°C (or lower temperature) to +250°C. °C (or higher temperature) for long-term use. However, the mechanical properties of silicone rubber such as tensile strength and tear resistance are poor, and its physical and mechanical properties are not as good as most synthetic rubbers at room temperature. Poor, so silicone rubber is not suitable for ordinary conditions, but very suitable for many specific occasions. [0003] Styrene-butadiene rubber (SBR), also known as polystyrene butadiene copolymer. Its physical...
