Description
Technical field
The invention belongs to rubber materials, be specifically related to a kind of dielectric resilience rubber.
Background technology
Neoprene is with chlorobutadiene as primary raw material, and by homopolymerization or other monomer copolymerizations on a small quantity, it is resistance to
The performances such as hot, fast light, ageing-resistant, oil resistant are superior to natural rubber, butadiene-styrene rubber, butadiene rubber.And neoprene has relatively
Strong flame resistance, excellent fire retardance and resistance to water.But its electrical insulation capability and tolerance to cold are poor so that it is at electric wire, electricity
The application such as cable is greatly limited.
Summary of the invention
It is an object of the invention to provide a kind of dielectric resilience rubber.This rubber improves its electrical insulating property and tolerance to cold.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of dielectric resilience rubber, by weight, is prepared by following raw material: 70-80 part neoprene, the poly-second of 10-20 part two
Alcohol, 5-10 part conch meal, 20-30 part corn straw, 8-10 part APP, 0.5-1 part age resistor and 3-5 part vulcanizing agent.
Preferably, by 76 parts of neoprenes, 12 parts of Polyethylene Glycol, 10 parts of conch meals, 24 parts of corn straw, 8 parts of polyphosphoric acids
Ammonium, 3 parts of age resistor and 4 parts of vulcanizing agents prepare.
Described age resistor is that 1:2 ratio is mixed to prepare by antioxidant D and antioxidant MB according to mass ratio.
Described vulcanizing agent is mixed to prepare for the ratio of 1:2 in mass ratio by benzoyl peroxide with magnesium oxide.
The preparation method of this dielectric resilience rubber, comprises the steps:
(1) corn straw is dried, grinding, crosses 100-120 mesh sieve, standby；
(2) corn straw, Polyethylene Glycol and APP that step (1) processed are sufficiently mixed, obtain compound；
(3), after neoprene, step (2) gained compound, conch meal, age resistor being sufficiently mixed, mill mixing is put into；So
After add vulcanizing agent, prepare elastomeric compound, the most mixing temperature is 60-80 DEG C, and roll spacing is 3-5mm, and mixing time is 30-
40min；
(4) being vulcanized by step (3) gained elastomeric compound, obtain neoprene, wherein curing temperature is 130-150 DEG C, sulfuration
Pressure is 5-7MPa, and cure time is 25-30min.
The remarkable advantage of the present invention:
(1) remaining stem and leaf part after corn straw refers to the gramineae farm crop maturation threshings such as Oryza sativa L., Semen Tritici aestivi, Semen Maydis, it is main
Wanting composition is cellulose.On the one hand, cellulose plays the effect of reinforcement；On the other hand, cellulose is a kind of polyol,
When burning, substantial amounts of carbon can be formed；It forms Intumescent Retardant System with APP, during burning, it is possible to obtain
Layer of charcoal is covered in the surface of comburant such that it is able to isolation heat and the transmission of oxygen, so that burning can not proceed.This
With the addition of conch meal in invention is a kind of inorganic material, will not burn, it is possible to preferably improve the fire resistance of rubber.
(2) Polyethylene Glycol used by can be good at playing the effect of plasticising, not only makes corn straw and APP more preferable
Mixing, moreover it is possible to reduce the brittle temperature of rubber, thus improve the tolerance to cold of rubber.
(3) due in the strand of neoprene link configuration asymmetric, its polar group or polar chain festival-gathering are along with friendship
The orientation of the direction generating period of changed electric field and electrically conductive, therefore the insulating properties of neoprene are not good enough.But shellfish used
Shell powder, its main component of 95% is calcium carbonate, has good antistatic performance, its porous fibrous double helix structure energy
Ionic impurity in enough absorbent insulation materials the most well, reduces because of the big concentration of the free ion of Leakage Current, and then plays and carry
The effect of high electric insulation performance.
In summary, gained rubber of the present invention has the antistatic property of excellence, insulating properties, fire resistance and resists cold
Property, and then greatly expanded its range of application.
