preparation example Construction

[0050] The present invention also provides a preparation method of the polyphenylene ether resin composition described in the above technical solution, comprising the following steps:

[0051] The prepared raw materials are put into a twin-screw extruder for melt extrusion and granulation to obtain a polyphenylene ether resin composition.

[0052] In the present invention, the method of adding the preparation raw materials into the twin-screw extruder preferably includes: adding polyphenylene ether resin from the first weight feeder port; mixing the remaining preparation raw materials, and feeding the obtained mixture from the second weight feeder The mouth of the device is added. In the present invention, the mixing of the remaining preparation raw materials is preferably carried out under stirring conditions, and the stirring speed is preferably 100-150 rpm; the stirring time is preferably 2-3 minutes.

[0053] In the present invention, when the flame retardant is liquid, i...

Abstract

The invention provides a polyphenyl ether resin composition and a preparation method thereof, and a wire duct and a preparation method thereof, and relates to the technical field of composite materialextrusion molding. The polyphenyl ether resin composition provided by the invention comprises the following preparation raw materials in parts by weight: 50 to 75 parts of polyphenyl ether resin, 10to 30 parts of polystyrene resin, 4 to 10 parts of a toughening agent, 1 to 3 parts of polyolefin, 5 to 15 parts of a flame retardant, 1 to 5 parts of a smoke suppressant, 0 to 5 parts of an inorganicmicro-nano filler, 0 to 1 part of a lubricant, 0 to 0.5 part of a main antioxidant, and 0 to 0.5 part of an auxiliary antioxidant. The polyphenyl ether resin composition provided by the invention hasexcellent flame retardancy and high temperature resistance, is relatively low in smoke density during combustion, has high impact toughness and scratch resistance, and is suitable for an extrusion molding process of the wire duct and use in an extreme environment.

Description

technical field [0001] The invention relates to the technical field of extrusion molding of composite materials, in particular to a polyphenylene ether resin composition and a preparation method thereof, a wire groove and a preparation method thereof. Background technique [0002] PVC is a non-crystalline polymer, mainly used in the preparation of pipes and wire insulation grooves. PVC used in wire insulation grooves has the advantages of excellent flame retardancy and convenient molding, but PVC has low temperature resistance and begins to soften at 65-85°C, requiring a low ambient temperature for use, and PVC has poor thermal stability. Under the action of PVC, PVC will gradually decompose and release HCl. When burning, it will also produce HCl toxic gas and produce a lot of smoke, which seriously endangers the environment and human health. [0003] Polyphenylene ether resin (PPO) has good mechanical properties, high temperature resistance, hydrolysis resistance, flame re...
