Heatproof impact-resistant nylon pipe dedicated for automobile

Abstract

The invention discloses a heatproof impact-resistant nylon pipe dedicated for automobile. The nylon pipe is prepared by extruding a modified nylon composite material, which comprises the following raw materials in parts by weight: 100 parts of nylon, 20 to 35 parts of low density polyethylene, 3 to 10 parts of maleic anhydride grafted polyethylene, 3 to 8 parts of polymethylhydrosiloxane, 5 to 15 parts of epoxy resin, 3 to 10 parts of nano calcium carbonate, 2 to 10 parts of aminated carbon nanotube, 3 to 10 parts of nano silicon dioxide, 5 to 12 parts of melamine cyanurate, 1 to 5 parts of organic nano montmorillonite, 2 to 10 parts of polytetrafluoroethylene, 5 to 15 parts of ethylene propylene diene monomer, 2 to 5 parts of ethylene bisstearamide, 0.5 to 2 parts of calcium stearate, 1 to 3 parts of coupling agent, 15 to 35 parts of diethyl aluminum phosphinate, and 1 to 2.5 parts of lanthanum stearate. The provided heatproof impact-resistant nylon pipe dedicated for automobile has the advantages of excellent heatproof, flame retardant, and impact resistant properties and long service life.

Description

technical field [0001] The invention relates to the technical field of nylon tubes, in particular to a special heat-resistant and impact-resistant nylon tube for automobiles. 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 h...

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, the addition of inorganic materials to nylon tends to reduce the impact resistance of the resulting composite
