Description
Technical field
The present invention relates to a kind of thermoplastic elastomer electric wire and cable material and preparation method thereof, can be widely used in fields such as automobile, electric, construction work, belong to chemical material technical field.
Background technology
Thermoplastic elastomer is called as third generation rubber, is a kind of fluidity of molten of caoutchouc elasticity and thermoplastics and material of repeat performance of having concurrently.Because its excellent physical and mechanical properties, electrical insulation properties and process industrial art performance, and be widely used in various fields such as automobile, electric, electric wire, medicine equipment, building packing, progressively replaced vulcanized rubber and nonrigid plastic.The styrene-butadiene-styrene block polymer is the thermoplastic elastomer of current production rate maximum, but owing to contain more pair of key in the molecular chain, be easy to by oxygen and ozone ageing degraded, thus heat-resisting and environment resistant poor, limited its application at wires and cables industry.
Summary of the invention
The object of the present invention is to provide a kind of heat-resisting and environment resistant good a kind of thermoplastic elastomer electric wire and cable material and the preparation method.
For realizing above purpose, technical scheme of the present invention provides a kind of thermoplastic elastomer electric wire and cable material, it is characterized in that, it is made by following raw materials by weight percent:
Polypropylene 68-90%,
Rubber 8-30%,
Vulcanizing agent 0.1-0.5%,
Oxidation inhibitor 0.1-1%,
Lubricant 0.1-1%;
Described polypropylene is a Co-polypropylene, and its melting index is 10-90g/10min; Described vulcanizing agent is a kind of organo-peroxide; Described organo-peroxide is a dicumyl peroxide.
Described rubber is the styrene-butadiene-styrene block polymer, described oxidation inhibitor is Hinered phenols antioxidant or composite with phosphite ester kind antioxidant, its Hinered phenols antioxidant is 1010, composite with 1 phosphite ester kind antioxidant is 1010 and 168 composite, described lubricant is a fatty acid metal soap class, and fatty acid metal soap class is calcium stearate, Zinic stearas, barium stearate, Magnesium Stearate.
A kind of preparation method of thermoplastic elastomer electric wire and cable material is characterized in that, its method is as follows:
(1) weighs raw material by weight percentage;
(2) all raw materials are put into high-speed mixer and mixing 2-5 minute;
(3) discharging;
(4) raw materials mixed is put into screw rod machine extruding pelletization, the rotating speed of screw rod machine is 180-600 rev/min, and temperature is 180-200 ℃.
Styrenic rubber has excellent physical and mechanical properties, electrical insulation properties and process industrial art performance.The adding of vulcanizing agent makes double bond content decline in the rubber, has improved the ageing-resistant performance of material.
Oxidation inhibitor makes polyethylene possess good processing stability in the course of processing, avoids color and luster, performance to change.Lubricant is used for improving Drawing abillity.
The present invention adopts styrenic rubber as matrix, makes a kind of thermoplastic elastomer electric wire and cable material.
Advantage of the present invention is to adopt the elastomerics of excellent property, cooperates advanced formulating of recipe, has prepared a kind of thermoplastic elastomer electric wire and cable material, and is heat-resisting and environment resistant good, compliance with environmental protection requirements.
