Abstract

The invention discloses a modified SEBS (styrene-ethylene / butadiene-styrene block copolymer) alloy and a preparation method thereof. The SEBS alloy is prepared from the following components in parts by weight: 80-100 parts of styrene block copolymer, 2-5 parts of white oil, 25-35 parts of polyolefin elastomer and 30-40 parts of antimony chromate / titanium dioxide nano composite material, wherein the antimony chromate / titanium dioxide nano composite material is synthesized by antimony nitrate, ammonium metachromate, 3-nitro-1, 2, 4- triazole-5-ketone and nano TiO2. According to the invention, the antimony chromate / titanium dioxide nano composite material is added, thus, degree of crystallinity of the SEBS alloy material is improved, and flexural modulus, hardness, tensile strength and other properties of the modified SEBS alloy are all improved to a greater extent.

Description

[0001] technical field

[0002] The invention relates to the technical field of modified polymers, in particular to a modified SEBS alloy and a preparation method thereof.

[0003] Background technique

[0004] Styrene block copolymer (SEBS) is a new type of multi-purpose thermoplastic elastomer, which is called "the fourth generation rubber" in the scientific and technological circles. SEBS is a linear three-block copolymer with polystyrene as the terminal block and ethylene-butene copolymer obtained by hydrogenation of polybutadiene as the middle elastic block. SEBS has good stability, weather resistance, heat resistance and compression deformation resistance, but its mechanical properties are not very good. There are not many articles about the modified SEBS of nanoparticle materials at present, and the present invention adopts antimony chromate / titanium dioxide (SbCrO 3 / TiO 2 ) Nanomaterials modified SEBS, which improves the crystallization properties of the materia...
