Thermoplastic polyurethane composite material and preparation method thereof

The invention is applicable to the technical field of macromolecular materials and provides a thermoplastic polyurethane composite material and a preparation method thereof. The thermoplastic polyurethane composite material comprises the following components: thermoplastic polyurethane (TPU), basalt fiber, a compatilizer, an antioxidant and a lubricating agent. The thermoplastic polyurethane composite material takes the TPU as a matrix component, and each component generates synergistic effect in a melted extrusion process, so that the thermoplastic polyurethane composite material has high mechanical properties and heat resistance, such as tensile property and notch shock resistance, in particular the tensile property is excellent. The thermoplastic polyurethane composite material is simple in process, takes the basalt fiber serves as a reinforced material and is natural and environment-friendly. The production condition is easy to control, the cost is low, and the requirement on equipment is low, so the thermoplastic polyurethane composite material is suitable for industrialized production.
