The present invention discloses a kind of automobile exhaust pipe, and it is made up of following raw material:Steel, aluminium, copper material, linear alkyl benzene sulphonate, OPEO, ethylene glycol, phosphoric acid, sodium dichromate, zinc oxide, micron order graphite fibre, micron order potassium feldspar.The present invention is mainly modified by adding linear alkyl benzene sulphonate, OPEO, ethylene glycol, phosphoric acid, sodium dichromate, graphite fibre and potassium feldspar on the basis of the original material of automobile exhaust pipe, to improve its rustless property;Wherein, linear alkyl benzene sulphonate, OPEO, ethylene glycol, phosphoric acid, sodium dichromate, potassium feldspar can not only be effectively promoted the osmosis between these raw materials and steel, aluminium, copper material; it product is formed layer protecting film, have the function that antirust;Particularly potassium feldspar, it can be effectively promoted interpenetrating between each raw material, reduce the space of automobile exhaust pipe, further improve its rustless property.

Description

Automobile exhaust pipe
Technical field
The present invention relates to technical field of automobile accessories, more particularly to a kind of automobile exhaust pipe.
Background technology
Automobile exhaust pipe plays damping noise reduction for the effect of automobile fuselage, extends the work in exhausting silencer system life-span With.The main material of blast pipe is stainless steel.For in general automobile, because pressure is very when the waste gas of automobile leaves engine Greatly, its caused noise may allow people to feel and go mad, and at this moment play a part of the blast pipe that main noise reduction is exactly automobile, Its internal installation muffler, the noise of automobile greatly reduces.And its main operational principle is to make air-flow point by multichannel Stream, these shuntings are only shown in that rubs mutually is hit so that the flow velocity of air-flow gradually reduces, and such iterative cycles are final that waste gas is led to Cross the emission by exhaust pipe outflow of automobile so that lower noise, so as to reach the effect that routine vehicle reduces noise.
At present, with the development of automobile industry, the continuous enhancing of people's awareness of safety, the performance of original blast pipe is It is difficult to the performance requirement for meeting that automobile industry is with rapid changepl. never-ending changes and improvements.For example, existing automobile exhaust pipe is in the prevalence of getting rusty easily Problem.Therefore, how improving the rustless property of automobile exhaust pipe will be one of following research direction of automobile industry.
The content of the invention
The present invention provides a kind of automobile exhaust pipe, and the automobile exhaust pipe can solve existing automobile exhaust pipe presence and get rusty easily The problem of.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
It is prepared from the following raw materials in parts by weight:100 parts~200 parts of steel, 20 parts~60 parts of aluminium, copper material 10 parts~30 Part, 4 parts~6 parts of linear alkyl benzene sulphonate, 1 part~3 parts of OPEO, 1 part~5 parts of ethylene glycol, phosphoric acid 5 Part~10 parts, 5 parts~10 parts of sodium dichromate, 0.1 part~0.5 part of zinc oxide, 1 part~2 parts of micron order graphite fibre, micron order potassium 1 part~2 parts of feldspar.
In above-mentioned technical proposal, more specifically technical scheme can also be:In the steel, the content of ferro element is 75% More than.
Further, in the aluminium, the content of aluminium element is more than 25%.
Further, in the copper material, the content of copper is more than 5%.
Further, it is made up of following steps:
First by above-mentioned steel, aluminium, copper material heating melting, linear alkyl benzene sulphonate, octyl phenol polyoxy second are then added Alkene ether, ethylene glycol, phosphoric acid, sodium dichromate, zinc oxide, micron order graphite fibre and micron order potassium feldspar, are uniformly mixed, And through smelting, being cast into slab;Then, manufactured slab heated, cooled down, temper;Finally, by slab rolling into Type.
Due to using above-mentioned technical proposal, the beneficial effect that the present invention obtains is:
The present invention on the basis of the original material of automobile exhaust pipe mainly by adding linear alkyl benzene sulphonate, octyl phenol APEO, ethylene glycol, phosphoric acid, sodium dichromate, graphite fibre and potassium feldspar are modified, to improve its rustless property; Wherein, linear alkyl benzene sulphonate, OPEO, ethylene glycol, phosphoric acid, sodium dichromate, potassium feldspar not only may be used With the osmosis being effectively promoted between these raw materials and steel, aluminium, copper material, product can be also set to form layer protecting film, Have the function that antirust;Particularly potassium feldspar, it can be effectively promoted interpenetrating between each raw material, reduce automobile exhaust The space of pipe, further improve its rustless property.
