Abstract

The invention belongs to the technical field of high polymer materials and discloses a continuous long fiber reinforced thermoplastic polyurethane material and a preparation method thereof. The continuous long fiber reinforced thermoplastic polyurethane material disclosed by the invention comprises the following components in parts by weight: 200-800 parts of thermoplastic polyurethane, 800-200 parts of continuous long fiber reinforcing agent, 10-30 parts of compatilizer, 10-20 parts of antioxidant, 2-6 parts of lubricating agent and 5-10 parts of crosslinking agent. Compared with the prior art, the continuous long fiber reinforced thermoplastic polyurethane material disclosed by the invention is simple in structure, reasonable in design and strong in practicability; and a long glass fiber reinforced thermoplastic polyurethane material is adopted, thereby greatly improving the rigidity and strength of the material and obviously improving the anti-impact property and heat-resistant property of the material.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a continuous long fiber reinforced thermoplastic polyurethane material and a preparation method thereof. Background technique [0002] TPU (thermoplastic polyurethane elastomer) is a new type of plastic. Due to its good processability, weather resistance and environmental protection, TPU is widely used in shoe materials, pipes, films, rollers, cables and wires and other related industries. The outstanding features of thermoplastic polyurethane elastomers are excellent wear resistance, excellent ozone resistance, low temperature resistance, good oil resistance, chemical resistance and environmental resistance, and the hydrolysis stability of polyether esters in humid environments far exceeds polyester type. However, the thermoplastic polyurethane elastomer material itself has disadvantages such as low strength and poor heat resistance, which greatly limit it...
