Abstract

The invention discloses a high-fluidness PC / TPU (polycarbonate / thermoplastic urethane) alloy material and a preparation method thereof. The high-liquidity PC / TPU alloy material comprises the following compositions in percentage by weight: 60-80% of polycarbonate, 10-30% of thermoplastic polyurethane elastomer, 3-10% of compatilizer, 5-10% of toughening agent, and 0.5-1% of fluidness improver. The high-liquidity PC / TPU alloy material prepared by using the method disclosed by the invention concurrently has the advantages of PC and TPU, and is good in low-temperature impact resistance, coating performance and solvent resistance and excellent in fluidness; and the preparation method can be implemented in one step through granulation by using a double-screw blending extrusion process, so that the preparation method is simple in process, convenient to operate, high in efficiency, low in cost, and suitable for being applied to industrial production.

Description

[technical field]

[0001] The invention relates to the field of polymer materials, in particular to a PC / TPU alloy material with high fluidity and a preparation method thereof. [Background technique]

[0002] PC (Polycarbonate, polycarbonate) is an engineering plastic with excellent comprehensive properties. It has high dimensional stability, good electrical insulation and creep resistance, etc., and is widely used in machinery and electronics industries. However, because bisphenol A polycarbonate contains benzene rings in the molecular chain, the molecular chain is rigid, which makes its melt viscosity larger, inconvenient to process, prone to stress cracking and notch impact sensitivity, and it also has poor solvent resistance and poor wear resistance. . TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer) has excellent wear resistance, oil resistance and cold resistance.

[0003] If the alloy material of PC and TPU can be obtained, this alloy material ...
