Problems solved by technology

[0003] The disadvantages of adding low-temperature glass to high-temperature thermoplastics are: 1. The price of low-temperature glass that matches the melting temperature of high-temperature thermoplastics is high, resulting in high overall prices of high-temperature thermoplastics and poor market competitiveness
2. Since the melting temperature of ordinary glass is above 800 degrees, this method is not suitable for ordinary glass
4. The surface energy of molten glass is different from that of molten polymer materials, making it difficult to mix completely uniformly

Abstract

The invention provides a preparation method of high molecular glassy alloy. High molecular materials in a container are heated to a molten state; a stirrer is arranged in the molten high molecular materials and glass powder (fiber) is heated to 0 to 800 degrees above the melting point of high molecular materials; a quantitative feeding device is used to add the high-temperature glass powder (fiber ) into the molten high molecular materials and the stirrer in the molten high molecular materials evenly mixes the high-temperature glass powder (fiber) into the molten high molecular materials; after cooling and molding, the high molecular glassy alloy particles or products are made.

Description

Field of invention: [0001] The invention relates to polymer materials and equipment, especially materials and equipment made of glass and polymer resin. Background technique: [0002] According to WPC report: Siemens has developed a glass-plastic composite material that adds a large amount of low-temperature glass to high-temperature thermoplastics, such as: liquid crystal polymers, polyethersulfone, polyetherimide and Made from polyphenylene sulfide, the new polymer can contain up to 80% glass by mass. This is because the glass component is in a molten state during production and blending, so it does not affect the glass content when it contains a large amount of glass components. Material mobility. This material has the advantages of flame retardancy, high heat resistance and dimensional stability. [0003] The disadvantages of adding low-temperature glass to high-temperature thermoplastics are: 1. The price of low-temperature glass matching the melting temperature of hi...
