Problems solved by technology

However, due to the poor melt fluidity of polyphenylene ether itself, the temperature for melt blending reaction extrusion is generally very high, far exceeding the boiling point of maleic anhydride monomer, and its molecular chain lacks grafts with high reactivity. point, this process has great difficulties in industrial practical application

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] 1. Preparation of PPO / PA alloy modified compatibilizer

[0028] (1) Glycidyl methacrylate (GMA) and styrene (St) are configured into a mixed solution according to a mass ratio of 1:1, and then the initiator dicumyl peroxide, which accounts for 5% of the total graft monomer (DCP) was added to the grafted monomer mixture to dissolve;

[0029] (2) Mix the polyphenylene ether PPO and graft monomer mixture in a mixer for 5-10 minutes, and the graft monomer mixture accounts for 8% of the total mixture weight;

[0030] (3) Put the mixed total mixture into the torque rheometer for melting and grafting reaction, the reaction temperature is 220-250°C, the rotation speed is 50-70rpm, and the reaction time is 6-10min.

[0031] (4) After the reaction, the material was cooled, and then pulverized by a pulverizer to obtain particles of functionalize...

Abstract

The invention relates to a modification compatibilizer of PPO / PA (Poly-p-phenylene oxide / polyacrylate) alloy and a PPO / PA alloy. The compatibilizer is characterized by being a grafted copolymer of polyphenyl ether, glycidyl methacrylate and styrene; and the PPO / PA alloy with the compatibilizer is characterized by comprising the following components in percentage by weight: 50-59.5% of polyphenyl ether, 31.5-40.4% of nylon, 0.1-18% of the compatibilizer and 0.1-0.5% of antioxidant. Compared with the prior art, the prescription of the compatibilizer matching with the PPO / PA disclosed by the invention can be used for greatly improving the compatibility of the PPO / PA alloy and improving the mechanical property and water resisting property of the PPO / PA alloy and is in good condition of industrial application.

Description

technical field [0001] The invention relates to the field of polymer alloys, in particular to a PPO / PA alloy modified compatibilizer and a PPO / PA alloy. Background technique [0002] As a typical representative of engineering plastic alloys, PPO / PA alloy combines the respective advantages of polyphenylene oxide (PPO) and nylon (PA). Through the complementary performance of each component, the overall performance is better than any single component. The PPO / PA alloy material is a very important high-performance product in the modified polyphenylene ether alloy. PPO / PA alloy is widely used in automobile, machinery, electrical and electronic, office equipment and other industries due to its excellent mechanical properties, heat resistance, dimensional stability and processing fluidity. [0003] Polyphenylene ether is a non-polar amorphous polymer, and nylon is a polar crystalline polymer. Simple blending of the two will inevitably lead to two-phase separation, poor interface a...
