Abstract

The invention relates to a polyamide poly(phenylene oxide) resin composition and a preparing method thereof. The composition is prepared from following raw materials by weight: 30-60 parts of bifunctional polyamide, 10-30 parts of monofunctional polyamide, 10-25 parts of poly(phenylene oxide), 5-10 parts of an elastic block copolymer and 1-5 parts of functional elastic polyolefin. The raw materials are mixed in a high-speed mixer, and the mixture is added into a double-screw extruder and is subjected to melting extrusion and granulation to obtain the composition. Compared with the prior art, the composition has good flowing properties and also have excellent shock resistance, thus overcoming the problem that processing performance and shock performance cannot be obtained at the same time in the prior art.

Description

technical field [0001] The invention belongs to the field of polymer material alloys, and in particular relates to a polyamide polyphenylene ether resin composition and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPE) resin is one of the five major engineering plastics, with excellent heat resistance, dielectric properties, hydrolysis resistance and dimensional stability; and polyamide is also one of the five major engineering plastics, with excellent chemical resistance and heat resistance, but polyamide has poor dimensional stability and strong water absorption! Therefore, the polyamide polyphenylene ether resin composition has good heat resistance, dimensional stability, chemical solvent resistance and processability. [0003] However, the compatibility between non-polar polyphenylene ether resin and polar polyamide resin is poor! There are many research reports on the compatibilization of polyamide polyphenylene ether resin composit...
