Abstract

The invention discloses a flame-retardant insulation liner material for an electric safety helmet. The flame-retardant insulation liner material contains the following raw materials in parts by weight: 70-90 parts of high-fluidity ABS resin, 3-7 parts of nano-silicon dioxide, 2-6 parts of nano-silicon nitride, 1-3 parts of a silane coupling agent, 2-3 parts of polyvinyl alcohol, 2-3 parts of chitosan, 8-12 parts of a flame retardant agent, 8-14 parts of short fibers, 2-6 parts of a flame retardant synergist, 5-7 parts of a processing aid, 0.5-1.5 parts of an antioxidant, 0.4-1.2 parts of a light stabilizer and 1-2 parts of a compatilizer. The liner material disclosed by the invention has excellent mechanical properties, strong strength and good flame retardance, puncture resistance, shock absorption performance and electrical insulation property and can resist impact and aging; meanwhile, the preparation method of the liner material has the beneficial effects that the raw material components are safe, reliable and harmless to the environment, the raw materials are easily available and relatively low in cost, the process is simple, clear and easy in operation, the industrial production is easily realized, and the preparation method has relatively high practical values and good application prospects.

Description

technical field [0001] The invention relates to the technical field of electric power materials, in particular to a flame-retardant insulating lining material for electric safety helmets and a preparation method thereof. Background technique [0002] The electric safety helmet, also known as the safety helmet, is a shallow dome hat made of steel or similar materials worn to protect the top of the head, and it is a protective product that prevents impact objects from hurting the head. When the worker's head is impacted by falling objects, the impact force will be decomposed to the entire area of ​​the skull in an instant by using the shell and lining of the helmet, and then use the various parts of the helmet: the structure of the shell, the lining, The elastic deformation, plastic deformation and allowable structural damage of materials and buffer structures (sockets, tethers, sutures, buffer pads, etc.) absorb most of the impact force, so that the final impact force on the ...
