Abstract

The invention discloses a thermoplastic composite elastomer, and a preparation method and application of the elastomer. The thermoplastic composite elastomer comprises the following raw materials in parts by weight: 18.0-45.0 parts of thermoplastic elastomer, 26.0-73.0 parts of paraffin oil, 1.0-7.0 parts of polyhydric alcohol, 0.5-6.0 parts of a compatilizer, 32.0-166.0 parts of a filler and 1.0-5.0 parts of an assistant, wherein the thermoplastic elastomer is a composite of a polar thermoplastic elastomer and a nonpolar thermoplastic elastomer; the polar thermoplastic elastomer is one or two of acrylic rubber and a thermoplastic polyurethane elastomer; the nonpolar thermoplastic elastomer is one or two of a hydrogenated styrene-butadiene segmented copolymer and a polyolefin elastomer. Compared with the prior art, the thermoplastic composite elastomer achieves overall effects of environment friendliness, high bonding strength and excellent mechanical properties and is a preferable material of a plastic track.

Description

technical field [0001] The invention belongs to the technical field of polymer material composites, and in particular relates to a thermoplastic composite elastomer, a preparation method and uses thereof. Background technique [0002] Compared with the traditional cinder track, the plastic track has the advantages of good flatness, high compressive strength, appropriate elasticity and excellent wear resistance, and has been recognized as the most excellent outdoor sports venue in the world. Since the development of plastic runways in the United States in the 1960s, plastic runways have been widely used in sports venues and leisure venues such as schools, stadiums, and parks. [0003] At present, the plastic runway is mainly formed by bonding and laying rubber particles with adhesives, and the commonly used adhesives are mainly polyurethane adhesives. In the actual application of plastic track, a large number of waste tire rubber particles are added to the polyurethane adhes...
