Description

Electric power overhaul tool radiation protection insulating materials and preparation method thereof
Technical field
The invention belongs to rubber materials, and in particular to a kind of electric power overhaul tool radiation protection insulating materials and its preparation side Method.
Background technology
In electric system, electrician usually needs live line work, has the danger of electric shock to avoid staff during the work time Danger, people are set with the radiation protection insulating materials with insulating properties, but at present such on the electric power overhaul tool used in electrician Material often obtains in terms of insulation performance, water resistance, resistance to behaviour of ozone, heat-resistant aging, low temperature resistant, resistance to chemical corrosion Less than satisfaction, it is also required that this product has environmental-protecting performance；Therefore, there is an urgent need for a kind of new electric power overhaul tool radiation protection insulation Material solves the above problems.
Invention content
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of electric power overhaul tool radiation protection insulating materials, With good insulation performance, heat-resistant aging and wearability, the present invention also provides preparation methods.
Electric power overhaul tool radiation protection insulating materials of the present invention, including internal layer and outer layer；
Wherein internal layer is made of the raw material of following mass fraction：1-2 parts of Corvic, 2-3 parts of butadiene rubber, ternary 4-5 parts of EP rubbers, 3-5 parts of paraffin oil, 1-2 parts of attapulgite, 2-3 parts of sulphur, 0.5-0.8 parts of carbon black, 1-2 parts of magnesium hydroxide With 3-5 parts of anti-aging agent；
Outer layer is：Polyimides.
Wherein：The mass ratio of internal layer and outer layer is 10:1.
Anti-aging agent is 2,2,4- trimethyl 1,2- dihydro quinolines.
The present invention is used as rubber by using 1-2 parts of Corvic, 2-3 parts of butadiene rubber, 4-5 parts of ethylene propylene diene rubber Glue material of main part ensures that product has good insulation performance and wearability.
The present invention makes product have higher hardness, and netted polyimides can promote by adding netted polyimides The fusion of urethane rubber, brombutyl and ethylene propylene diene rubber.
Outer layer of the present invention uses polyimides, can effectively prevent solar exposure aging its internal layer, can also play anticorrosion and Wear-resisting effect.
