Abstract

The invention discloses a polycarbonate-containing styrene thermoplastic elastomer composite material, and a preparation method of a formed body made of the composite material. The polycarbonate-containing styrene thermoplastic elastomer composite material comprises styrene thermoplastic elastomer, polycarbonate resin, a compatibilizer, white mineral oil, a photothermal stabilizer, a lubricant and an inorganic filler. The preparation method of the formed body comprises the following steps: premixing the above components in a high speed mixer for 3-10min, allowing the obtained premix to go through a double screw extruder, carrying out melt extrusion at 150-280DEG C, carrying out cooling granulation, and carrying out injection molding to obtain the formed body. The polycarbonate-containing styrene thermoplastic elastomer composite material and the formed body have the advantages of light weight, high wear resistance, high slip resistance, stable dimension, low temperature resistance, and excellent tensile strength and tear strength.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polycarbonate-containing styrene-type thermoplastic elastic composite material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is an amorphous, tasteless, odorless, non-toxic and transparent thermoplastic polymer. Although PC has a typical rigid molecular chain, it has excellent toughness, toughness and rigidity, which makes it PC has the advantages of excellent impact toughness, transparency, dimensional stability, electrical insulation, creep resistance, weather resistance, non-toxicity, wide service temperature, wide adaptability, etc. Small, creep deformation and water absorption size change are small. But its disadvantages, such as easy environmental stress cracking, poor processability, high price, etc., limit the application of PC in many fields. [0003] Thermoplastic elastomer is a kind of copolymer with bl...
