[0002] Polycarbonate (PC) has excellent mechanical and electrical properties, and is widely used in the preparation of electrical components. Polycarbonate is often selected as the material for wall switch panels, but wall switches made of polycarbonate are installed in kitchens and other high-smoke environments. Cracking often occurs, causing safety hazards, so it is urgent to develop a polycarbonate material with good oil cracking resistance

Abstract
The invention discloses a polycarbonate material, and a preparation method and application thereof. The polycarbonate material is prepared from the following components in percentage by mass: 50-85% of polycarbonate, 5-20% of poly(4-methyl-1-pentene), 5-20% of thermoplastic polyurethane elastomer, 1-5% of a first component compatilizer, 1-5% of a second component compatilizer, 5-15% of a flame retardant, 0.3-1.0% of an antioxidant, and 0.3-1.0% of a lubricant. The polycarbonate material has excellent impact toughness, good flame-retardant property and electrical insulation property, and the oil cracking resistance has very good improvement at the same time, so that the polycarbonate material is very suitable for preparing wall switches and other products. The preparation method of the polycarbonate material, disclosed by the invention, adopts general-purpose equipment for preparing the polycarbonate material, is simple in preparation, can realize industrial production easily, and has broad application prospects.
Description
technical field [0001] The invention relates to a polycarbonate material and its preparation method and application. Background technique [0002] Polycarbonate (PC) has excellent mechanical properties and electrical properties, and is widely used in the preparation of electrical components. Polycarbonate is often selected as the material for wall switch panels, but wall switches made of polycarbonate are installed in kitchens and other high-smoke environments. Cracking often occurs, causing safety hazards, so it is urgent to develop a polycarbonate material with good oil cracking resistance. Contents of the invention [0003] The invention provides a polycarbonate material and its preparation method and application. The material has good oil cracking resistance while maintaining other properties of the material. [0004] To achieve the above object, the technical scheme adopted in the present invention is as follows: [0005] A polycarbonate material is characterized in...
