Abstract

The invention provides a composite material based on polyimide nanofibers. The material is prepared from the following raw materials in parts by weight: 50 to 60 parts of bisphenol A polycarbonate, 10 to 20 parts of ultra-high molecular weight polyethylene, 15 to 25 parts of polyimide nanofiber, 3 to 5 parts of glass fiber, 4 to 8 parts of nano boron fiber, 4 to 6 parts of coupling agent, 3 to 5 parts of amino-terminated hyperbranched polyimide, 4 to 6 parts of 2-acrylamido-2-methylpropanesulfonic acid and 2 to 3 parts of phosphorus pentoxide. The invention relates to a high-temperature-resistant plastic which is prepared from the following components in parts by weight: 0.5-1 part of polyphosphoric acid, 1-2 parts of an initiator, 1-3 parts of 1, 3-bis (oxiranyl methyl)-5-(2-propenyl)-1, 3, 5-triazine-2, 4, 6 (1H, 3H, 5H)-triketone, 2-4 parts of a heat stabilizer and 1-3 parts of an antioxidant. The invention further discloses a preparation method of the composite material based on the polyimide nanofibers. The composite material based on polyimide nanofibers disclosed by the invention has the advantages of high strength, light weight, ultraviolet resistance, sufficient heat aging resistance, flame retardance, temperature resistance, good moisture resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite material based on polyimide nanofibers for a dorsal arch skeleton of safety rubber boots and a preparation method thereof. Background technique [0002] Safety rubber boots are essential protective equipment that needs to be worn in the working environment of mining operations, tunnel construction, fire rescue, oil exploration, etc., which can prevent the construction workers from being disabled. The ideal safety rubber boots need to be smash-proof, kick-proof, puncture-proof, slip-proof and moisture-proof at the same time. The safety rubber boots currently used generally use steel plates in order to prevent the foot surface from being smashed. This type of safety boots has a low safety factor, simple and rough process structure, and the steel material used is cumbersome and has no elasticity and cushioning function. People wearing it for a long time will...
