Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a thermoplastic polyurethane composite material and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane (TPU) is a kind of (A-B) n-type linear multi-block polymer composed of thermodynamically incompatible hard segments and soft segments alternately, with a unique microphase separation structure, so its physical and mechanical properties are quite excellent . Its outstanding features are high hardness, high strength, good elasticity, low temperature resistance, excellent wear resistance, excellent ozone resistance, good oil resistance, chemical resistance and environmental resistance. Therefore, it is widely used in injection molding and extrusion. , calendering and dissolving into solution resin and other processing methods, and its products cover the range of industrial applications and civil necessities. Commonly used ...
