preparation example Construction

[0055] The preparation method of above-mentioned thermoplastic elastomer material, comprises the following steps:

[0056] S110, uniformly stirring the TPV, the lubricant, and the maleic anhydride-grafted polypropylene to obtain a first mixture.

[0057] In one embodiment, the stirring is carried out in a horizontal mixer, and the stirring rate is 20r / min-40r / min, preferably 30r / min-40r / min.

[0058] In one of the embodiments, stirring is carried out at room temperature (23° C.) for 5 min to 10 min, preferably 8 min to 10 min.

[0059] S120. Mix and stir the first mixture evenly with the mineral filler, UV absorber, modified polyethylene wax and antioxidant to obtain a premix.

[0060] In one embodiment, the stirring is carried out in a horizontal stirrer, and the stirring rate is 40r / min-60r / min, preferably 50r / min-60r / min.

[0061] In one of the embodiments, stirring is carried out at room temperature (23° C.) for 10 min to 15 min, preferably 20 r / min to 40 r / min.

[0062...

Embodiment 1

[0070] Put 90 parts of American santoprene's TPV101-55 into a horizontal mixer, add 3 parts of Exxon Mobil's maleic anhydride grafted polypropylene PO1020 and 5.5 parts of Dow Corning's lubricant MB50-001, at room temperature (23 ℃ ) and a rotation speed of 20 r / min for 5 min to obtain the first mixture.

[0071] Put the first mixture into a horizontal mixer, add 1 part of mineral filler SiO 2 , 0.5 parts of Clariant's polytetrafluoroethylene modified polyethylene wax 3920F, 0.15 parts of antioxidant (Basf's antioxidant 168 and antioxidant 1076 are compounded in a ratio of 2:1) and 0.1 part of UV absorbing Agent UV-P, stirred for 10 minutes at room temperature with a rotational speed of 40r / min to obtain a premix.

[0072] The premix was extruded in a twin-screw extruder with a rotation speed of 150 r / min and a length-to-diameter ratio of 24:1, and pelletized to obtain a thermoplastic elastomer material.

Embodiment 2

[0074] Put 85 parts of American santoprene's TPV101-55 into a horizontal mixer, add 8 parts of Exxon Mobil's maleic anhydride grafted polypropylene PO1020 and 2 parts of Dow Corning's lubricant MB50-001, at room temperature (23°C) Under the condition of 40r / min, the rotation speed was stirred for 10min to obtain the first mixture;

[0075] The first mixture is put into a horizontal mixer, adding 4.5 parts of mineral filler carbon black, 0.5 part of Clariant's polytetrafluoroethylene modified polyethylene wax 3920F, 0.15 parts of antioxidant (Basf's antioxidant 168 Mix with antioxidant 1076 at a ratio of 2:1) and 0.2 parts of ultraviolet absorber UV-770, and stir for 10 minutes at room temperature (23°C) at a speed of 60r / min to obtain a premix.

[0076] Put the premix into a twin-screw extruder with a rotating speed of 200r / min and a length-to-diameter ratio of 36:1 to extrude and pelletize to obtain a thermoplastic elastomer material.

Abstract

The invention relates to a thermoplastic elastomer material, and a preparation method thereof. The thermoplastic elastomer material comprises 70 parts to 90 parts of polyolefin alloy thermoplastic elastomer, 3 parts to 13 parts of maleic anhydride grafted polypropylene, 1 part to 10 parts of a mineral filler, 0.1 parts to 0.5 parts of an ultraviolet absorber, 2 parts to 6 parts of a lubricant and0.5 part to 1 part of modified polyethylene wax. Mutual cooperation of the raw material components is achieved, and it is found through experiment determination that the thermoplastic elastomer material is excellent in wear resistance and tear resistance.

Description

technical field [0001] The invention relates to a thermoplastic elastomer material and a preparation method thereof. Background technique [0002] Traditional bicycles have risks such as easy rupture of pneumatic tires and air leakage, which makes the use process inconvenient. In recent years, there have been two types of bicycle air-free tires: air-free solid tires and air-free hollow tires. Considering the structure and comfort of the tire, the current non-pneumatic tire material is mainly thermoplastic elastomer. Thermoplastic elastomer is a kind of polymer material that has both rubber and thermoplastic properties. However, the thermoplastic elastomer materials currently used in non-inflatable tires have poor temperature resistance, are easy to tear, and are not wear-resistant. The deformation is large, the tire contact area increases, the riding resistance increases, and the riding comfort is poor. Contents of the invention [0003] Based on this, it is necessary ...
