Abstract

The invention discloses an environment-friendly sports floor based on highly flame-retardant clay composite material. The environment-friendly sports floor comprises the following raw materials: polypropylene, fillers, flame retardants, clay, antioxidants, compatibilizers and stabilizers. The highly flame-retardant clay composite material effectively overcomes a shortcoming that toughness of the existing materials is difficult to balance, and has the advantages of excellent low temperature resistance and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the field of polymer materials for indoor or outdoor sports floors, and in particular to an environmentally friendly sports floor based on high flame-retardant clay composite materials. Background technique [0002] Polypropylene is an ordinary general-purpose plastic, which is polymerized from propylene monomer. The material has poor heat resistance, a melting point of 165-175°C, low rigidity, low impact toughness, relatively low hardness, poor low temperature resistance, and is easy to burn , In the field of modified plastics, its rigidity, toughness, low temperature resistance and flame retardancy are difficult to improve at the same time, and it cannot be directly used as raw materials for outdoor and indoor sports floors. [0003] The characteristics of clay mainly lie in mechanical properties, including hardness, fracture toughness and low temperature ductility of...
