Abstract

The invention discloses a polyphenylene oxide / polyamide 6 blend alloy. The polyphenylene oxide / polyamide 6 blend alloy is prepared from the components in the following parts by weight: 20-80 parts of polyphenylene oxide, 10-40 parts of polyamide 6, 5-35 parts of compatilizer, 5-15 parts of toughener, 0.2-0.5 parts of antioxidant, 0.2-0.7 parts of lubricant, and 3-35.5 parts of auxiliaries. The invention further discloses a preparation method for the polyphenylene oxide / polyamide 6 blend alloy and an application for the polyphenylene oxide / polyamide 6 blend alloy as an extruded profile material. The PPO / PA6 (polyphenylene oxide / polyamide 6) blend alloy material disclosed by the invention is high in strength, good in toughness, excellent in corrosion resistance and insulativity, capable of replacing a steel plate or a special engineering plastic, thus realizing the purpose of replacing steel by plastic. Moreover, the PPO / PA6 blend alloy material can be popularized to extruded profiles, as well as is good in wear resistance, heat resistance and dimensional stability, easy to machine and form, and capable of being used by replacing the profiles of stainless steel, PEEK (poly ether ether ketone) and the like in a very large range, thus greatly reducing cost.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyphenylene ether / nylon 6 (PPO / PA6) blended alloy material and its preparation method and application. Background technique [0002] With the progress of society and the development of science and technology, people's life is becoming more and more convenient, and at the same time, people are paying more and more attention to the environment. Polyphenylene oxide (PPO) is a thermoplastic engineering plastic with excellent performance, which has the following advantages: (1) Excellent physical and mechanical properties. Small density, non-toxic, high mechanical strength, good creep resistance, low molding shrinkage; (2) Excellent heat resistance. Glass transition temperature (T g ) is the highest among thermoplastics, about 210°C, and its melting point is about 260°C. It can work continuously in the temperature range of 160-190°C. The creep resistance at high temper...
