Abstract
The invention discloses a high-strength ethylene propylene diene monomer and a preparation method thereof. The ethylene propylene diene monomer is characterized by being prepared by the following components in parts by weight: 90-110 parts of ethylene propylene diene monomer, 2-8 parts of acrylic acid, 0.4-1 part of initiator and 1-5 parts of sodium stearate. The high-strength ethylene propylene diene monomer has excellent mechanical property, and can be used for preparing medium-high-voltage power cables, motor lead wires, marine cables and the like.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of high-strength ternary ethylene-propylene rubber(EPR) and preparation method thereof.
Background technology
Terpolymer EP rubber (EPDM) is the rubber being formed through solution copolymerization by ethene, propylene, then introduces the 3rd monomer (ENB).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 a kind of high-strength ternary ethylene-propylene rubber(EPR) is provided.
Another object of the present invention is to provide the preparation method of above-mentioned high-strength ternary ethylene-propylene rubber(EPR).
The object of the invention is to realize in the following manner:
An ethylene-propylene rubber(EPR) is to be made by the component of following weight part:
90～110 parts of terpolymer EP rubbers, 2～8 parts, vinylformic acid, 0.4～1 part of initiator, 1～5 part of sodium stearate.
Above-mentioned terpolymer EP rubber is preferably made by the component of following weight part: 100 parts of terpolymer EP rubbers, 4～6 parts, vinylformic acid, 0.4～0.6 part of initiator, 2～3 parts of sodium stearate.
Described initiator is peroxide initiator.Described peroxide initiator is preferably dicumyl peroxide (DCP).
The preparation method of above-mentioned high-strength ternary ethylene-propylene rubber(EPR) comprises the following steps: terpolymer EP rubber, vinylformic acid, initiator, sodium stearate are added to extruding pelletization in twin screw extruder, and the screw speed adopting 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 using stearate to make it to form physics after terpolymer EP rubber carboxyl grafting monomer, having improved the intensity of virgin rubber.Meanwhile, by increasing suitable subsidiary material, guarantee that other over-all propertieies of material that obtain are all stable again, to meet the demand of market diversification.
