Abstract

The invention discloses high-modulus polyvinyl alcohol fiber reinforced PPO / PA6 alloy and a preparation method thereof. According to the alloy, polyvinyl alcohol fibers contained in the alloy are used as a reinforcing material to replace conventional glass fibers, so that the prepared alloy has the characteristics of high strength, high toughness, high modulus, collision cracking prevention, excellent compatibility, size stability, stress cracking resistance and the like, and can overcome the defect of large brittleness of a glass fiber reinforced material. The high-modulus polyvinyl alcohol fiber reinforced PPO / PA6 alloy is safe, has excellent strength, rigidness, heat resistance and mechanical stability, good compatibility, and can be applied to various electronic parts, inserts, chemical appliances and other parts, even construction, aviation and other fields.

Description

technical field [0001] The invention relates to the technical field of alloy preparation, in particular to a high modulus polyvinyl alcohol fiber reinforced PPO / PA6 alloy and a preparation method thereof. Background technique [0002] In recent years, with the development of various materials towards the lightweight direction of replacing steel with plastic, polyphenylene oxide (PPO) and polyamide 6 (PA6) with high heat resistance, flame retardancy and chemical resistance are prepared Materials are increasingly being used in various electrical appliances, electronic components, connectors, chemical equipment and other components, and even construction and aviation. [0003] Polyphenylene ether (PPO) resin is non-toxic, transparent, low relative density, and has excellent mechanical strength, stress relaxation resistance, creep resistance, heat resistance, water resistance, water vapor resistance, dimensional stability and other advantages. In addition, the dielectric consta...
