Problems solved by technology

The prefabricated rubber runway needs to go through refining, banburying, and vulcanization. The process is complicated, and the equipment and production costs are high. At the same time, sulfur is used as the vulcanizing agent of natural rubber. The finished product has a strong sulfur smell, resulting in poor sports experience.
CN106633425A, CN106519463A, CN106496819A have reported a kind of method that uses EPDM material to produce prefabricated runway, and the production process also needs to go through banburying, open refining, vulcanization link, and process is complicated, and equipment and production cost price are high

Abstract

The invention discloses an environment-friendly odorless prefabricated plastic runway coiled material. The coiled material is composed of the following components in parts by weight: 5 to 20 parts ofthermoplastic polyurethane, 0 to 10 parts of ethylene-propylene-diene monomer, 5 to 20 parts of a styrene thermoplastic elastomer, 0 to 5 parts of polypropylene, 20 to 40 parts of calcium carbonate, 25 to 30 parts of naphthenic oil, 1 to 2 parts of an anti-aging agent, 1 to 2 parts of an antioxidant, 1 to 3 parts of an anti-ultraviolet absorbent and 4 to 7 parts of a pigment. The invention furtherdiscloses a preparation method of the environment-friendly odorless prefabricated plastic runway coiled material. Compared with the traditional prefabricated runway coiled material, the prefabricatedrunway coiled material has the advantages of being low in production investment cost, simple in process, free of vulcanization, environmentally friendly, odorless, excellent in physical and chemicalperformance and high in cost performance, and the performance meets the requirements of the new national standard GB36246-2018.

Description

technical field [0001] The invention belongs to the technical field of plastic runways, and in particular relates to an environmentally friendly and odor-free prefabricated plastic runway coil and a preparation method thereof. Background technique [0002] Prefabricated roll rubber track is the preferred material for international sports venues, with high comprehensive professional performance. The rubber runway has fast construction, simple maintenance, good paving effect and stable product performance. It is an excellent material widely praised by the public at this stage. The prefabricated coiled rubber runway is based on natural rubber and artificial rubber, mixed with environmentally friendly fillers, stabilizers and colorants, after continuous calendering treatment by professional equipment, and catalyzed at a high temperature of 280-300 ° C, it is mechanically embossed. The finished product after molding is a double-layer synthetic structural rubber with consistent t...
