Problems solved by technology

Although SEBS has excellent rubber elasticity, excellent weather resistance, low temperature resistance, environmental protection performance, etc., there are some problems in using SEBS as an elastomer material alone. For example, compared with traditional vulcanized rubber, SEBS has excessive rigidity, Disadvantages such as large compression deformation and high density; its upper limit of service temperature, solvent resistance, oil resistance, etc. are usually inferior to traditional vulcanized rubber, etc.

Embodiment approach

[0046]In the present application, the PP is a polypropylene resin, which includes at least one of homopolypropylene, copolymerized polypropylene and random copolymerized polypropylene. The addition of polypropylene resin can make the molecular chain of SEBS rubber resin more flexible, thereby increasing the elasticity of the product, making it have a soft feel and mechanical performance. In addition, polypropylene also has strong resistance to chemical attack, thereby improving the chemical corrosion resistance of SEBS thermoplastic elastomers. PP is cheap and can reduce the cost of using SEBS. During the experiment of the applicant, homopolypropylene has better compatibility with vinylpyridine-grafted SEBS and better mechanical properties than copolypropylene and random polypropylene. As a preferred embodiment of the present invention, the PP is homopolypropylene with a melt index of 8.6.

Embodiment approach 1

[0071] Embodiment 1, TPE tension pipe material, the TPE tension pipe material is prepared from raw materials including the following parts by weight:

[0072] SEBS45-55 copies

[0073] PP65-80 copies

[0074] Vinylpyridine graft SEBS10-20 parts

[0075] POE1-13 copies

[0076] 45-75 parts of white oil.

Embodiment approach 2

[0077] Embodiment 2 is the same as Embodiment 1, except that the SEBS is in powder form, and the degree of hydrogenation is >95%.

Abstract

The present invention discloses a TPE pulling force pipe material and a preparation method thereof, the TPE pulling force pipe material comprises SEBS, PP, vinylpyridine grafted SEBS, POE and white oil; and the preparation method is as follows: according to the weight ratio, weighing the raw materials, fully uniformly mixing the SEBS, the PP, the vinylpyridine grafted SEBS, the POE and the white oil in a high speed mixer to obtain a mixture; and putting the obtained mixture in a screw extruder for extrusion granulation. The TPE pulling force pipe material has high flexibility, high strength and good weathering resistance, and is suitable for the preparation of fitness equipment.

Description

technical field [0001] The invention relates to the technical field of polymer materials, more specifically, the invention relates to a TPE tension pipe material and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, fitness activities are becoming more and more popular in people's lives, and fitness equipment is becoming more and more miniaturized and miniaturized. The tension tube can be used outdoors and indoors, which is easy to carry and effectively improves physical activity. , to shape the perfect body curve, so it has become one of people's favorite sports equipment. The material of the tension tubes currently sold in the market is mainly natural latex or synthetic latex. Latex material has good elasticity, air permeability and anti-mite functions. At present, it is more used to make mattresses, pillows, throw pillows, lumbar pillows, cushion sponges, balloons, gloves and other products, but the tension t...
