Abstract

The invention relates to a preparation method of a cable sheath material. The preparation method comprises the steps of firstly putting a raw rubber matrix into a torque rheometer, and mixing the raw rubber matrix uniformly for 3-5 minutes; then adding a reinforcing agent, a coupling agent, anti-aging agents, anti-scorching agents, plasticizers, an acid absorbent and flame retardants to the torque rheometer to be mixed; when the mixing temperature is 90-105 DEG C, adding vulcanizing agents, vulcanization accelerators and vulcanization accelerating agents, and mixing the components uniformly for 3-15 minutes, thus preparing a rubber compound body when the mixing temperature is 130-165 DEG C; using an open mill to carry out mill running on the rubber compound body three-four times, discharging sheets and placing the sheets; then stripping and discharging the sheets on a three-roll calender, and cooling the output rubber pages with cooling rolls, thus preparing a finished product. The preparation method has the beneficial effects that sulfonated polyethylene is adopted as a main body to ensure that the cable sheath rubber has good chemical mediator corrosion resistance, ozone oxidation resistance and oil corrosion resistance, and meanwhile, the material has good flame retardance.

Description

Technical field [0001] The invention belongs to the field of rubber material preparation, and particularly relates to a method for manufacturing a cable sheath material. Background technique [0002] In recent years, due to the shortage of resources such as petroleum and coal at home and abroad, countries have vigorously developed new energy sources. As a clean energy source, wind energy has an inexhaustible source of energy saving and environmental protection. However, the cable accessories for wind power generation cannot keep up with the requirements of wind power generation. Wind power generation cables are difficult to maintain and use harsh conditions, so the cable performance and life expectancy are high, and the cables are constantly twisted during operation. At present, natural rubber and styrene-butadiene rubber are more commonly used for cable sheathing rubber. This type of cable sheathing rubber has good elasticity, but has poor weather resistance and is prone to agin...
