Abstract
The invention discloses a railway passenger carriage nylon hose. The railway passenger carriage nylon hose is composed of the following raw materials in parts by weight: 86-90 parts of nylon 610, 2-3 parts of isotactic polypropylene, 1-2 parts of zinc oxide, 3-4 parts of chloroacetic resin, 12-18 parts of di-n-octyl phthalate, 0.4-1 part of butyl tin trioctoate, 0.6-0.9 part of fenbendazole, 4-6 parts of hydrophobic fumed silica, 1-2 parts of 3-aminopropyltrimethoxysilane, 2-3 parts of N-butylbenzenesulfonamide and 10-15 parts of flame retardant master batch. The hose is safe and environment-friendly, high in tensile strength and corrosion resistance, good in wear resistance, good in pressure and ultraviolet resistance, and high in flame resistance; detected by an authoritative department, the railway passenger carriage nylon hose satisfies the technological conditions of the railway passenger carriage nylon hoses.
Description
Technical field
The present invention relates generally to tubing field, relates in particular to a kind of railroad coach nylon hose.
Background technology
Railroad coach electric wire, cable protective sleeve mostly are metallic hose at present, and metallic hose quality is overweight, and inconvenience is installed, and work-ing life is short, the more and more difficult needs that meet Railway Market.Nylon hose glossiness, snappiness are good, rub resistance, corrosion-resistant, flame retardant properties is good, and alternative metals flexible pipe has become trend, therefore, develops a railroad coach nylon hose imperative.
In the end of the year 2012, railway main office below, requires metallic hose unification to be replaced by nylon hose, and has issued " railroad coach nylon hose technical qualification " and require each rolling stock plant to carry out by this technical qualification.In technical qualification, require that nylon hose is withstand voltage, rub resistance, halogen-free environmental, resistance to-40 ℃ low temperature, detect by DIN5510-2, and reach S4, SR2, ST2, toxicity FED < 1.My department fills a prescription by research and development, and product reaches this technical requirements.
Summary of the invention
The object of the invention is exactly for a kind of railroad coach nylon hose is provided.
The present invention is achieved by the following technical solutions:
A kind of railroad coach nylon hose, it is made up of the raw material of following weight parts:
NYLON610 86-90, isotatic polypropylene 2-3, zinc oxide 1-2, vinyl chloride-vinyl acetate resin 3-4, dinoctyl phthalate 12-18, three sad butyl tin 0.4-1, fenbendazole 0.6-0.9, hydrophobicity aerosil 4-6,3-aminopropyl trimethoxysilane 1-2, N-butylbenzene sulphonamide 2-3, fire-retardant master granule 10-15;
Described fire-retardant master granule is made up of the raw material of following weight parts:
Aluminium sesquioxide 10-16, Graphene 6-10, eight bromo ether 2-3, antimonous oxide 1-2, Silane coupling agent KH550 0.6-1, oxidized polyethlene wax 2-4;
Above-mentioned antimonous oxide is joined in 3-5 times of water, stir and add above-mentioned aluminium sesquioxide, Graphene, eight bromo ether, at 60-80 ℃, be stirred to water dry, add oxidized polyethlene wax, 100-200 rev/min of dispersed with stirring 4-6 minute, adds Silane coupling agent KH550, and ball milling is even, oven dry is sieved, and obtains described fire-retardant master granule.
Its preparation method is by isotatic polypropylene, zinc oxide, vinyl chloride-vinyl acetate resin, dinoctyl phthalate, three sad butyl tin, fire-retardant master granule mixed melting, extrusion granulator; Mix with other composition again, send into twin screw extruder and melt extrude granulation, the cooling nylon hose material that obtains.
Advantage of the present invention is:
Flexible pipe safety and environmental protection of the present invention, tension erosion resistance is strong, and wear resistance is good, and withstand voltage ultraviolet resistance is good, and flame retardant properties is strong, and product detects through authoritative department, meets " railroad coach nylon hose technical qualification ".
