Problems solved by technology

For example, in the field of electronic products such as TV sets and mobile phones, there are high requirements for many materials. For example, materials that can be applied to TVs and mobile phones are often required to have high strength, good heat resistance, good electrical properties and good However, the current materials rarely meet multiple requirements at the same time. For example, materials with high strength may lose transparency and optical properties, while materials with good transparency and optical properties may be resistant to There are losses in heat, strength, and electrical properties, so these electronic fields need more materials with good comprehensive properties

Abstract

The invention provides a high-heat-resistant transparent reinforcement material applied to televisions as well as a preparation method and application thereof. The high-heat-resistant transparent reinforcement material is prepared from polymethacrylate, polycarbonate, alicyclic polyimide, glass fiber, antioxidants and processing aids under cooperation of formulation dosage. The polymethacrylate cooperates with the polycarbonate to improve the basic transparency of the material; the alicyclic polyimide is added into the material and cooperates with the polymethacrylate and the polycarbonate to cooperatively enhance the transparency and the optical performance of the material; the alicyclic polyimide can also cooperate with the glass fiber to enhance the strength and the heat resistance of the material; all the components cooperate with each other, so that the electrical performance of the material is also obviously improved; when being used as a household appliance material, especially a television material, the high-heat-resistant transparent reinforcement material has great advantage and can meet technical requirements on the materials in the industries.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a heat-resistant transparent reinforcing material and its preparation method and application, in particular to a high heat-resistant transparent reinforcing material for television, its preparation method and application. Background technique [0002] With the development of society, people have more and more diverse requirements for material properties, such as higher and higher requirements for transparency, translucency, and optical properties. For example, in the field of electronic products such as TV sets and mobile phones, there are high requirements for many materials. For example, materials that can be applied to TVs and mobile phones are often required to have high strength, good heat resistance, good electrical properties and good However, the current materials rarely meet multiple requirements at the same time. For example, materials with high strength may los...
