Abstract
The invention relates to ethylene-propylene-diene tire sidewall rubber. The sidewall rubber provided by the invention is prepared by using natural rubber, ethylene-propylene-diene rubber, polyisoprene rubber and regenerated rubber powder through mixing in cooperation with other adjuvants. Not only can the sidewall strength and tear resistance be enhanced, but also the sidewall rubber can be used for a long time, and the sidewall rubber has excellent thermal aging resistance, ozone aging resistance, weather aging resistance and chemical stability, good elasticity and compression resistance and excellent water resistance.
Description
Technical field
The invention belongs to sidewall rubber technical field, be specifically related to a kind of terpolymer EP rubber sidewall rubber.
Background technology
Sidewall and tire both sides; it is the maximum position of lateral deformation; sidewall rubber is thinner; in order to protect carcass from physical abuse and daylight, erosion by wind and rain; its damage type is flex crack, physical abuse, and therefore sidewall rubber should have good strength and extension property and the performance such as flex cracking resistance, resistance to atmospheric aging.
Though cis-1,4-polybutadiene rubber can improve the flex fatigue life of sidewall rubber, sidewall intensity and tear-resistant performance also decline thereupon, and the cement properties of rubber unvulcanizate is also bad.Therefore need to develop a kind of new sidewall rubber sizing compound formula, make tire have better properties, strengthen its flex fatigue life, strengthen its sidewall intensity and tear-resistant performance.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of terpolymer EP rubber sidewall rubber.The mixing of the natural rubber that sidewall rubber of the present invention adopts, terpolymer EP rubber, polyisoprene rubber and ground rubber, other auxiliary materials are coordinated to not only increase sidewall intensity and tear-resistant performance, and can life-time service, there is excellent heat-proof aging, resistance to ozone ageing, Weather-resistant and chemical stability, good elasticity and crushing resistance, remarkable water tolerance.
A kind of terpolymer EP rubber sidewall rubber of the present invention is realized by following technical scheme: described sidewall rubber comprises the component of following portions by weight:
Natural rubber 30-90 terpolymer EP rubber 10-50
Polyisoprene rubber 10-50 ground rubber 10-30

Zinc oxide 1-8 anti-aging agent 1-10
Anti-recovery agent WK-9011-4 altax 0.5-2
Accelerant CZ 0.5-3 aromatic hydrocarbon oil 10-40.
Described natural rubber is 2# smoke sheet rubber or 3# smoke sheet rubber.
Described carbon black is N220 and N234.
Carbon black N220 and N234 mixes according to the ratio of weight ratio 1:1,
Described described anti-aging agent is Microcrystalline Wax and anti-aging agent RD.
Microcrystalline Wax and anti-aging agent RD mix according to the ratio of weight ratio 1:1.
Described described white carbon black is the precipitated silica of particle diameter 20-100nm.
Described a kind of terpolymer EP rubber sidewall rubber, is grouped into by following one-tenth by weight:
Natural rubber 40 terpolymer EP rubber 30
Polyisoprene rubber 20 ground rubber 10
Silane coupling agent Si-692 vulkacit H (HMT) 0.8
