Abstract

The invention relates to the technical field of macromolecule modification, in particular to a high-heat flame-retardant PPO (polyphenylene oxide) alloy material and a preparation method thereof. Thehigh-heat flame-retardant PPO alloy material is prepared from the following ingredients including PPO resin, HIPS (high impact polystyrene) resin, boron-containing organic silicone resin, titanium-containing organic silicone resin, SEBS (styrene-ethylene-butylene-styrene block copolymer), SEBS-g-MAH (maleic anhydride), a phosphorus-series flame retardant, nanometer silicon dioxide, nanometer titanium dioxide, a toughening agent, a cold resistant agent, an antioxidant and a lubricating agent. The modification is performed on the PPO resin and the HIPS resin through the boron-containing organicsilicone resin and the titanium-containing organic silicone resin, and SEBS and SEBS-g-MAH are combined for compatibility modification, so that the prepared PPO alloy material has both rigidity and flexibility. The PPO alloy material has the advantages of good heat-resistant flame-retardant performance and good mechanical performance; in addition, the injection molding process requirements can becompletely met, and the dyeing is easy. The preparation method has the characteristics that the preparation method is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of polymer modification, in particular to a high burning heat flame-retardant PPO alloy material and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPO) has excellent physical and mechanical properties, electrical properties, heat resistance, dimensional stability and weather resistance, but PPO has poor fluidity and difficult processing and molding, which restricts its application in automobiles, electronic appliances, and home appliances. applications in many fields. At present, this problem has been basically solved by means of alloying modification, which has also opened the application of polyphenylene ether in industries such as electronic appliances, office supplies, and auto parts. [0003] On the other hand, some components in electronic and electrical products may cause local overheating and may cause combustion due to poor contact, overload or short circuit, whic...
