Abstract
The invention discloses a functionalized SEBS (styrene-ethylene-butadiene-styrene) material and a preparation method thereof. The material is prepared from components in parts by weight as follows: 100 parts of SEBS, 4-5 parts of trinitride, 0.2-0.3 part of dicumyl peroxide, 0.1-0.15 part of an antioxidant and 0.4-0.5 part of ethylene bis-stearamide. After SEBS is functionalized, the tensile strength and the breaking elongation are improved, the material has polarity, and the application fields are expanded.

The object of the invention is to overcome above-mentioned weak point and a kind of functionalized SEBS material is provided.
Another object of the present invention is to provide the preparation method of this functionalized SEBS material.
The object of the invention is to realize in the following manner:
A kind of functionalized SEBS material, this material is made up of the component of following weight part:
Described oxidation inhibitor is antioxidant 1010.
Described triazo-compound is p-azidobenzoic acid.
The preparation method of described functionalized SEBS material, is characterized in that the method comprises the following steps:
Add SEBS and triazo-compound in the first hopper of the twin screw extruder of 1:48 to length-to-diameter ratio;
Dicumyl peroxide is added in the second hopper of this twin screw extruder;
Ethylene bis stearamide and oxidation inhibitor is added in the 3rd hopper of this twin screw extruder;
Second hopper is 20:48 with the distance of the first hopper and the ratio of screw rod overall length, and the 3rd hopper is 32:48 with the distance of the first hopper and the ratio of screw rod overall length, and twin screw extruder regional temperature arranges as shown in the table:
| Region | Machine barrel 1 district | Machine barrel 2 district | Machine barrel 3 district | Machine barrel 4 district | Machine barrel 5 district | Machine barrel 6 district |
| Temperature | 100℃ | 120℃ | 130℃ | 160℃ | 170℃ | 180℃ |
| Machine barrel 7 district | Machine barrel 8 district | Machine barrel 9 district | Machine barrel 10 district | Machine barrel 11 district | Machine barrel 12 district | Head |
| 190℃ | 210℃ | 210℃ | 210℃ | 200℃ | 180℃ | 185℃ |
Screw speed is preferably 50-90 rev/min.
Beneficial effect of the present invention compared with the prior art: SEBS and triazo-compound interact by the present invention, and functionalized rear raising tensile strength and elongation at break, also make it with polarity, can use in cable, petrochemical industry, add Application Areas.
