Problems solved by technology

[0003] The commonly used flame-retardant MPPO has poor melt fluidity, difficult molding, and cannot prepare large-scale parts; at the same time, as people pay attention to environmental protection, the international requirements for halogen-free flame-retardant materials, reducing or not using halogen-containing flame retardants is inevitable will become the trend of the industry
However, it is difficult to combine the flame retardancy, mechanical properties, fluidity, and rigidity after film formation of MPPO materials.

Abstract

The invention discloses a carbon fiber reinforced flame-retardant MPPO material for a rear shell of a television. The carbon fiber reinforced flame-retardant MPPO material comprises the following rawmaterials in parts by weight: 40-50 parts of HIPS resin, 25-40 parts of PPO resin, 2-5 parts of a toughening agent, 15-20 parts of a flame retardant, 0.3-0.5 part of an antioxidant, 0.5-2 parts of a lubricant and 5-15 parts of carbon fibers. The invention also discloses a preparation method for the carbon fiber reinforced flame-retardant MPPO material for the rear shell of the television. The carbon fiber reinforced flame-retardant MPPO material provided by the invention has the advantages of superstrong rigidity and flame retardancy, good flowability and excellent heat resistance, and has wide application prospect in molding of large workpieces and thin-walled products with heat resistance requirements and matching with an injection molding steam mold.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a carbon fiber-reinforced MPPO material for a flame-retardant TV rear case and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) is the fifth largest engineering plastic after polycarbonate PC, polyoxymethylene POM, polyamide PA, thermoplastic polyester PBT, and PET. It has high rigidity, high heat resistance, flame retardant, wear resistance, It has the advantages of pollution resistance, high strength and excellent electrical properties. Most of the PPO in the market is used after modification. It is common to modify it with high-impact polystyrene HIPS and polyamide PA, and most of them are HIPS. Modified polyphenylene ether, collectively referred to as MPPO, is the species with the lowest relative density among general engineering plastics. It has many advantages such as small linear expansion coefficient, good electrical propert...
