Conductive fibre-modified nylon pipe

Abstract

The invention discloses a conductive fibre-modified nylon pipe. The conductive fibre-modified nylon pipe consists of the following raw material formula components in parts by mass: 50 to 60 parts of polyethylene, 40 to 45 parts of polyformaldehyde, 35 to 40 parts of polytetrafluoroethylenem, 30 to 35 parts of polyurethane, 20 to 25 parts of conductive fibres, 3 to 5 parts of carbon fibres, 2 to 3 parts of pearl fibres, 2 to 3 parts of glass fibres, 3 to 5 parts of graphite fibres, 5 to 8 parts of rubber powder, 2 to 5 parts of metal fibres, 2 to 3 parts of asbestos fibres, 3 to 4 parts of plaster fibres, 3 to 5 parts of pyrite powder, 4 to 5 parts of calcite powder, 5 to 6 parts of kaolinite powder, 6 to 8 parts of titanium carbide, 3 to 5 parts of zinc oxide and 5 to 8 parts of an auxiliary agent. The conductive fibre-modified nylon pipe is high in mechanical strength, good in heat resistance and flame retardance, high in thermal stability, and good in impact resistance; a nylon pipe which is prepared by the conductive fibre-modified nylon pipe is long in service life. The nucleation rate of nylon is improved; the density of a system is improved; meanwhile, the heat conductivity of the system is improved; the tensile strength, the bending strength, the impact strength, the thermal deformation temperature, the creep resistance and the ultraviolet resistance of the conductive fibre-modified nylon pipe are improved.

Description

technical field [0001] The invention relates to the technical field of a nylon pipe, in particular to a conductive fiber modified nylon pipe. Background technique [0002] Nylon is a general term for thermoplastic resins containing repeated amide groups on the main chain of the molecule. Its name is determined by the specific number of carbon atoms in the synthetic monomer. It has superior mechanical strength, stiffness, toughness, mechanical shock absorption and wear resistance. , has gradually replaced metal and thermosetting materials and is widely used in auto parts. With the development of miniaturization of automobiles, some parts of automobiles are getting smaller and smaller, and the accessories are becoming more and more dense, which restricts the circulation of air, which makes it difficult to discharge the heat generated by automobiles in time, which will inevitably cause some The temperature of the parts increases, which places higher demands on the heat resista...

Problems solved by technology

At present, pure nylon materials can no longer fully meet the needs of the society, and it is often necessary to add modifiers to modify them. Among them, inorganic materials are commonly used modifiers for nylon, but the interfacial bonding force between inorganic materials and nylon is relatively weak. Low, after adding inorganic materials to nylon, the impact resistance of the resulting composite material will often be reduced. At the same time, nylon, as an organic material, also has the defect of poor flame retardancy, which limits the application of nylon pipes
