Description
Technical field
The present invention relates to automobile pipeline technical fields, and in particular to a kind of turbocharging pipeline and preparation method thereof.
Background technique
Currently, because turbocharging hose size is excessive, mainstream production technology is divided into two kinds at present in automobile pipeline system,
One kind is manual canoe, and for another kind to squeeze out knitting, the whole world has extremely a small amount of braiding production technology；
Winding production technology can be assisted by a locking equipment by hand, but there is still a need for consume a large amount of costs of labor, production effect
Low, and homogeneity of product is slightly worse, nonetheless but it is in aspect of performance greater advantage；Knitting is squeezed out using extrusion
Production equipment, enhancement layer use knitting, high production efficiency, and material cost is saved, therefore extrusion is widely used in the industry at present
Production technology, but relatively winding is poor by hand in terms of its properties of product.
As the environmental consciousness in global range is constantly promoted, motor vehicle emission requires constantly promoted, therefore small displacement
Engine application amount is sharply increasing, small displacement turbocharged engine at work compressed air and amount of fuel in lesser cylinder
It burns in body, therefore generates bigger high temperature and pressure exhaust gas, squeezing out knitting product to tradition is a kind of test.
Summary of the invention
The purpose of the present invention is to provide a kind of turbocharging pipeline and preparation method thereof, the present invention provides a kind of more efficient
Rate, the preparation method of safer environmental protection and high performance turbocharging pipeline.
The present invention solves its technical problem and adopts the following technical solutions to realize.
The invention proposes a kind of turbocharging pipelines, from inside to outside successively by barrier layer, the first enhancement layer, adhesive layer,
Second enhancement layer and protective layer composition, barrier layer with a thickness of 1.5~2.5mm, the first enhancement layer with a thickness of 0.1~0.2mm, glue
Layer is connect with a thickness of 0.8~1.5mm, the second enhancement layer with a thickness of 0.1~0.2mm, protective layer thickness is 1.5~2.5mm.
The present invention also proposes a kind of preparation method of above-mentioned turbocharging pipeline, comprising the following steps:
Internal layer barrier layer is squeezed out on plug, is then woven in the outer surface of barrier layer to form the first enhancement layer,
It is extruded into adhesive layer on the surface of the first enhancement layer, the second enhancement layer is formed in the surface weave of adhesive layer, finally second
Outer protective layer is squeezed out on enhancement layer, obtains semifinished tube embryo；By the cooling after cure of semifinished tube embryo, then cleaning cutting, is obtained
To turbocharging pipeline.
The beneficial effects of the present invention are:
The present invention provides a kind of turbocharging pipeline and preparation method thereof, turbocharging pipeline prepared by the present invention is promoted
The performances such as the outer diameter variation of product, burst pressure, impulse oscillation, finally improve the use function of product.
Specific embodiment
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, according to normal conditions or manufacturer builds
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
A kind of turbocharging pipeline provided in an embodiment of the present invention and preparation method thereof is specifically described below.
The embodiment of the present invention provides a kind of turbocharging pipeline, from inside to outside successively by barrier layer, the first enhancement layer, bonding
Layer, the second enhancement layer and protective layer composition, barrier layer with a thickness of 1.5~2.5mm, the first enhancement layer with a thickness of 0.1~
0.2mm, thickness of adhibited layer are 0.8~1.5mm, the second enhancement layer with a thickness of 0.1~0.2mm, protective layer thickness is 1.5~
2.5mm。
The embodiment of the present invention provides a kind of turbocharging pipeline, the turbocharging pipeline, from inside to outside successively by barrier layer,
First enhancement layer, adhesive layer, the second enhancement layer and protective layer composition, internal layer barrier layer is squeezed out first on plug, utilizes resin
The advantages that barrier material barotolerance (high-barrier) and high chemical resistance, so that turbocharging pipeline of the present invention has well
Barrier property and chemical resistance, then weave the first enhancement layer, recycle adhesive layer to be bonded, then weave the second enhancing
Layer enhances the performances such as the outer diameter variation for improving product, burst pressure, impulse oscillation using above-mentioned double layer fibre structure, so
After squeeze out protective layer, obtain the turbocharging pipeline of five-layer structure, the turbocharger tube of the five-layer structure in the embodiment of the present invention
The structure on road is totally different from the structure of the turbocharging pipeline of existing three-decker, and existing three-decker is for internal layer and outside
Layer between have braiding enhancement layer, due between internal layer and outer layer only have one layer of braiding layer, the mechanical strength of pipeline and
Burst pressure is all poor, especially small displacement turbocharged engine at work compressed air and amount of fuel in lesser cylinder
It burns in body, therefore generates bigger high temperature and pressure exhaust gas, above-mentioned three-decker is unable to satisfy requirement, and five in the present invention
The properties of turbocharging pipeline can be remarkably reinforced in layer structure, finally improve the use function of product.
In some embodiments, barrier layer is selected from nitrile rubber NBR, neoprene CR, chlorinated polyethylene rubber CM, second
Any one in alkene acrylic rubber AEM, acrylic rubber ACM or fluorubber FKM.
