Problems solved by technology

Traditional casters are generally hard plastic parts such as polypropylene PP, nylon PA, ABS, etc., but hard plastic has poor elasticity and has no cushioning and shock absorption effect
Another manufacturing material for casters is vulcanized rubber, thermoplastic polyurethane TPU, nitrile rubber NBR, etc., which have good resilience, but their flexural modulus is low and rigidity is insufficient, so their bearing weight is limited
At the same time, its processing procedures are cumbersome, which is not conducive to large-scale industrial production.

Abstract

The invention relates to an ultrahigh-resilience wear-resistant durable TPR trundle material and a preparation method thereof, and belongs to the technical field of preparation of new materials. The trundle material is prepared from the following components of hydrogenated styrene-ethylene-butylene-styrene elastomer, white oil, polypropylene, polyolefin elastomer, thermoplastic polyester elastomerTPC-ET, polyolefin PE and a processing aid. The preparation method comprises the following steps of a, weighing the raw materials according to ingredients; b, adding the weighed hydrogenated styrene-ethylene-butylene-styrene elastomer SEBS into a high-speed mixer, and uniformly spraying the white oil onto the surface of the SEBS elastomer to enable the white oil to be absorbed by the SEBS elastomer; c, sequentially adding the weighed polypropylene, polyolefin elastomer, thermoplastic polyester elastomer, polyolefin and processing aid into a mixer, and uniformly stirring to obtain a mixture; and d, pouring the prepared mixture into a twin-screw extruder, and carrying out melt extrusion granulation. The trundle material prepared by the invention has a relatively wider hardness range.

Description

technical field [0001] The invention relates to an ultra-high resilience, wear-resistant and durable TPR caster material and a preparation method thereof, belonging to the technical field of new material preparation. Background technique [0002] Materials have always been the basis of the industrial revolution. With the advent of the fourth industrial revolution, various high-tech industries such as aerospace, medical care, and large shopping malls are increasingly dependent on basic materials. At the same time, high-tech equipment Transportation is inseparable from various tool vehicles, so a wear-resistant, ultra-high resilience, and durable caster is particularly important at this time, acting as a basic component for rapid marching. Traditional casters are generally hard plastic parts such as polypropylene PP, nylon PA, ABS, etc., but hard plastic has poor elasticity and has no cushioning and shock absorption effect. Another manufacturing material of casters is vulcani...
