Abstract

The invention belongs to the field of lightweight materials, and particularly relates to a composite material of polyether block amide monomer foamed particles and polyurethane and a preparation method and application of the composite material of the polyether block amide monomer foamed particles and the polyurethane. The composite material comprises the polyurethane and the polyether block amide monomer foamed particles which are embedded into a polyurethane matrix, wherein the diameter of the foamed particles is 0.5-20 mm, the density of the foamed particles is 0.05-0.5 g/cm<3>, and the surfaces of the foamed particles are of closed pore structures. The prepared composite material has excellent tensile strength, low-temperature flexibility, high flexural fatigue resistance performance, high compressive deformation resistance performance and high rebound resilience, and can be effectively applied in shoe soles, tyres, bicycle saddles, interior decoration, buffer cushions, sound insulating pads, child toys and/or floor coverings.

Description

technical field [0001] The invention belongs to the field of lightweight materials, and in particular relates to a composite material of block polyetheramide elastomer foamed particles and polyurethane, a preparation method and application thereof. Background technique [0002] Polyetheramide thermoplastic elastomer (TPAE) is a block copolymer composed of high melting point crystalline polyamide hard segment and non-crystalline or amorphous polyester or polyether soft segment. Among them, the chemical composition of the hard segment and soft satin, the length of the molecular segment and the ratio of the two are diverse, which also determines the diversity of polyetheramide thermoplastic elastomer materials. In addition, TPAE material has the advantages of high mechanical strength, high toughness, good elasticity, low specific gravity, good bending fatigue resistance, good wear resistance and low temperature resistance. TPAE particles are used as the matrix, and a large num...
