preparation example Construction

[0030] A preparation method of high resilience and high wear resistance TPE caster material, comprising the following steps:

[0031] a. Weigh styrene-based elastomer, aromatic oil, polypropylene, powdered rubber, thermoplastic vulcanized rubber, polyurethane, ultra-high molecular weight polyethylene, auxiliary agent, and spare according to parts by mass.

[0032] b. Add the weighed styrene-based elastomer into the high-mixer, spray the aromatic oil over the high-mixer to the surface of the styrene-based elastomer through a sprayer, and stir while spraying, so that the aromatic oil is uniformly and fully Styrene elastomer absorption;

[0033] c. Add the weighed polypropylene, powdered rubber, thermoplastic vulcanizate, polyurethane, ultra-high molecular weight polyethylene, and auxiliary agents into the mixer in sequence and mix and stir at a high speed of 400r / min for 2 to 10 minutes until they are evenly stirred to obtain a mixture. During the stirring process, the temperat...

Abstract

The invention discloses a TPE trundle material with high resilience and high wear resistance and a preparation method. The TPE trundle material with high resilience and high wear resistance contains the following components in parts by weight: 100 parts of styrene elastomer, 20-170 parts of aromatic oil, 5-90 parts of polypropylene, 5-100 parts of powdered rubber, 5-130 parts of thermoplastic vulcanized rubber, 25-110 parts of polyurethane, 15-75 parts of ultrahigh molecular weight polyethylene and 10-135 parts of adjuvant. The preparation method for the TPE trundle material with high resilience and high wear resistance comprises the following steps: filling oil, blending, extruding and pelletizing. The trundle material prepared according to the invention has high compatibility with polypropylene; the trundle material can be coated and molded in the manner of secondary injection molding; the trundle material has excellent resilience performance, is nontoxic and environment-friendly andhas excellent processing property; the coating process is simple; the TPE trundle material has excellent abrasive resistance, high strength and high resilience; the service life of the trundle can beprolonged; the anti-shock and damping function of trundle can be achieved.

Description

technical field [0001] The invention relates to a caster material and a preparation method, in particular to a high-resilience and high-wear-resistant TPE caster material and a preparation method. Background technique [0002] With the rise of the industrial revolution, more and more equipment needs to be moved, and casters are being used more and more widely all over the world. Casters are almost inseparable from all walks of life. With the continuous development of modern technology, equipment is also required to have more and more functions, and casters have become an indispensable part. Most of the casters currently on the market are injection molded parts such as polypropylene and polyamide, but polypropylene and polyamide have poor elasticity and do not have the functions of shock resistance and shock absorption. Although elastomers such as rubber, polyurethane, and polyester elastomers have good shock resistance and shock absorption functions, they have low rigidity ...
