Problems solved by technology

However, the use of flame retardants is also limited by some factors. On the one hand, some flame retardants produce toxic gases when they are cracked and burned at high temperature, which is harmful to the human body; performance
Make it unusable in some areas with high safety requirements (such as high-speed rail vehicle interior parts, aerospace interior parts, ships, especially submarine interior parts, etc.)

Abstract

The invention relates to a high-flame-retardancy long-fiber-reinforced thermoplastic composite material and application thereof, belonging to the technical field of research and development, production and application of novel environment-friendly materials. By using polyphenyl thioether and polyphenyl sulfone as matrix plastics, compared with the traditional LFT-D (long-fiber-reinforced thermoplastic in direct processing), the oxygen index is enhanced by 52%, and the smoke density is lowered by 96%. The high-flame-retardancy long-fiber-reinforced thermoplastic composite material has favorable material characteristics, and thus, can effectively enhance the safety performance when being prepared into components and installing the components into high-speed rail interior equipment, aerospace interior equipment and vessel (especially submarine) interior equipment, thereby providing a new direction for the development in related fields.

Description

technical field [0001] The invention relates to a composite material and its application, in particular to a high flame-retardant long-fiber-reinforced thermoplastic composite material and its application, and belongs to the technical field of research, development, production and application of new environmental protection materials. Background technique [0002] LFT, long fiber reinforced thermoplastic material, English is Long Fiber reinforced Thermoplastics, compared with ordinary fiber reinforced thermoplastic materials, the plastic matrix in traditional LFT materials is mainly PP (polypropylene) and PA (nylon), although It has excellent performance, is environmentally friendly and can be recycled, but its application field is severely limited due to its flammability and high smoke concentration after burning. In the past, the flame retardant modification of plastics generally adopts the method of adding flame retardants, such as halogen-antimony-based flame-retardant s...
