Abstract
The invention discloses a kind of High-strength ethylene propylene diene monomer and preparation method thereof, it is characterized in that this terpolymer EP rubber is made up of the component of following weight part: terpolymer EP rubber 90 ~ 110 parts, 2 ~ 8 parts, vinylformic acid, initiator 0.4 ~ 1 part, sodium stearate 1 ~ 5 part.High-strength ethylene propylene diene monomer of the present invention has excellent mechanics mechanical property, can be used for preparation middle-high voltage power cable, motor lead and shipboard cable etc.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of High-strength ethylene propylene diene monomer and preparation method thereof.
Background technology
Terpolymer EP rubber (EPDM) through the rubber of solution copolymerization, then introduces Third monomer (ENB) by ethene, propylene.Terpolymer EP rubber is a kind of saturated superpolymer substantially, is the synthetic rubber of high comprehensive performance, has fabulous electrical property, aging resistance.But owing to not containing xln, so intensity is very low, the scope of application is very restricted.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point and a kind of High-strength ethylene propylene diene monomer is provided.
Another object of the present invention is to provide the preparation method of above-mentioned High-strength ethylene propylene diene monomer.
The object of the invention is to realize in the following manner:
A kind of High-strength ethylene propylene diene monomer is made up of the component of following weight part:
Terpolymer EP rubber 90 ~ 110 parts, 2 ~ 8 parts, vinylformic acid, initiator 0.4 ~ 1 part, sodium stearate 1 ~ 5 part.
Above-mentioned terpolymer EP rubber is preferably made up of the component of following weight part: terpolymer EP rubber 100 parts, 4 ~ 6 parts, vinylformic acid, initiator 0.4 ~ 0.6 part, sodium stearate 2 ~ 3 parts.
Described initiator is peroxide initiator.Described peroxide initiator is preferably dicumyl peroxide (DCP).
The preparation method of above-mentioned High-strength ethylene propylene diene monomer comprises the following steps: terpolymer EP rubber, vinylformic acid, initiator, sodium stearate are added extruding pelletization in twin screw extruder, and the screw speed adopted during extruding pelletization is 40-50 rev/min; Twin screw extruder temperature arranges as shown in the table:
Beneficial effect of the present invention compared with the prior art: the present invention is by being cross-linked into as from aggressiveness by using stearate to make it after terpolymer EP rubber carboxyl grafting monomer to form physics, improve the intensity of virgin rubber.Meanwhile, ensure that other over-all propertieies of material obtained are all stable, to meet the demand of market diversification by increasing suitable subsidiary material again.
