Halogen-free, fire-retardant, and glass fiber strengthened polyphenyl ether alloy material

Abstract

The invention provides a halogen-free, fire-retardant, and glass fiber strengthened polyphenyl ether alloy material, and belongs to the technical field of polymer materials. The material is composed of the following raw materials in parts by weight: 79 to 86 parts of polyphenyl ether resin, 12 to 19 parts of polystyrene resin, 21 to 27 parts of reinforced fiber, 15 to 21 parts of phosphate, 5 to 11 parts of high-efficient fire retardant, 0.6 to 1.2 parts of antioxidant, 0.8 to 1.5 parts of lubricant, and 1.3 to 2.5 parts of carbon black. The halogen-free, fire-retardant, and glass fiber strengthened polyphenyl ether alloy material has the following tested performance indexes: tensile strength of 65 to 82 MPa, bending strength of 78 to 94 MPa, notch impact strength of 60 to 80 j / m, and fire resistance of V-0 (UL-94-0.8mm), and is suitable for being applied to the production of thin-wall fire-retardant products.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a halogen-free flame-retardant glass fiber-reinforced polyphenylene ether alloy material. Background technique [0002] Polyphenylene ether material reinforced by glass fiber belongs to thermoplastic engineering plastics and is widely used in home appliances, office automation, construction and other fields. Modification of polyphenylene ether by glass fiber can expand the application range of polyphenylene ether material, but the glass fiber reinforced polyphenylene ether material has the deficiency of flame retardancy in the production of thin-walled products. In order to further improve the polyphenylene ether material The effect is applied in thin-walled products, so it is necessary to further improve its flame retardancy. In view of this, the applicant has made repeated and useful experiments, and finally formed the technical scheme to be introduced be...
