Abstract

The invention belongs to the field of polymer materials and molding processing thereof, and relates to a continuous glass fiber reinforced nylon 6 prepreg tape and a preparation method thereof. The continuous glass fiber reinforced halogen-free fire retardation nylon 6 prepreg tape is prepared from the following components by weight: 100 parts of nylon 6, 15-25 parts of a halogen-free fire retardation agent, 3-10 parts of a synergist, 2-10 parts of a compatibilizer, 0.5-1 part of a processing auxiliary agent, and 0.2-1 part of an antioxidant. Compared with the continuous glass fiber reinforced halogen-free fire retardation nylon 6 prepreg tape, the continuous glass fiber reinforced halogen-free fire retardation nylon 6 prepreg tape of the present invention has the following characteristics that: the technical problem of secondary disaster and carcinogenic substance release on production and environment due to dense smoke and hydrogen halide gas produced during fire retardation can be solved, and the production process does not require the solvent so as to reduce environmental pollution and hazard on production worker health and reduce corrosion on equipment.

Description

technical field [0001] The invention belongs to the field of polymer materials and their molding processing, and relates to a continuous glass fiber reinforced prepreg tape and a preparation method thereof. Background technique [0002] Nylon 6 has good physical and mechanical properties, wear resistance and self-lubricating properties, and at the same time has good fluidity and excellent processing performance. It is one of the most widely used engineering plastics and is widely used in automobiles, electronic appliances, industrial machinery, construction, etc. field. Unmodified nylon has poor flame retardancy, and its vertical combustion can only reach UL94 V-2 level (flammability UL94 level is the flammability standard for plastic materials), and its oxygen index is about 24, and it produces droplets during combustion. Falling is a flammable material that can easily cause a fire during use. With the increasing awareness of global safety and environmental protection, pe...
