Description
Technical field
The present invention relates to engine casting technology fields more particularly to a kind of engine to cast the dedicated reparation glue of cylinder body.
Background technique
The characteristics of engine casting cylinder body generallys use die-casting process and is made, die-casting process is using mold inner-cavity to thawing
Metal applies high pressure.Die-casting process is particularly suitable for manufacture a large number of small and medium-sized castings, therefore die casting is made in a variety of casting processes
With widest one kind.Compared with other casting technology, the surface of die casting is more smooth, possesses higher dimensional uniformity.
But using the engine casting cylinder interior of pressing process manufacture usually by a large amount of stomata, if the position of stomata
Near combustion chamber in engine casting cylinder body, combustion chamber gas leakage is easily caused.It is current for the engine casting cylinder body of gas leakage
It generallys use anaerobic adhesive to be repaired, if also gas leakage after repairing, is determined as waste product.It and is all usually at present to cast engine
Cylinder body is immersed in anaerobic adhesive, and then repressurization infiltrates anaerobic adhesive being filled into leakage hole.Engine casting cylinder body is using die casting
Aluminium alloy engine made of technique casts cylinder body, and the thermal expansion coefficient of aluminium alloy is differed with the thermal expansion coefficient of anaerobic adhesive after solidification
Very big, if leakage hole is larger, anaerobic adhesive is easily detached from leakage hole under the action of expanding with heat and contract with cold repeatedly after solidification, thus
Secondary gas leakage is generated, engine is caused to cast cylinder body premature failure, influences the service life of engine casting cylinder body.
Summary of the invention
The present invention is in view of the deficienciess of the prior art, provide a kind of engine casting dedicated reparation glue of cylinder body, specific skill
Art scheme is as follows:
A kind of engine casts the dedicated reparation glue of cylinder body, by polyurethane-type anaerobic adhesive, ferrocene, graphene powder, silicon carbide,
Solvent is mixed.
As an improvement of the above technical solution, the polyurethane-type anaerobic adhesive, ferrocene, graphene powder, silicon carbide, molten
The mass ratio of agent is 100:(7.1~7.9): (10.6~11.5): (5.6~6.3): (50~80).
As an improvement of the above technical solution, the partial size of the graphene powder is less than or equal to 100nm.
As an improvement of the above technical solution, the partial size of the silicon carbide is less than or equal to 100nm.
As an improvement of the above technical solution, the solvent is one of benzene, butanone, methylene chloride.
Beneficial effects of the present invention:
The reparation glue will not solidify at room temperature, and solidification temperature is 60~70 DEG C, and the shear strength of cured glue layer is high；?
Under the action of expanding with heat and contract with cold repeatedly, cured glue layer is not easy to be detached from leakage hole, and the probability that secondary gas leakage occurs is low, effectively
Engine is avoided to cast cylinder body premature failure, to extend the service life of engine casting cylinder body.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Embodiment 1
100kg polyurethane-type anaerobic adhesive, 7.1kg ferrocene, 10.6kg partial size are less than or equal to the Graphene powder of 100nm
Silicon carbide, the 50kg benzene of body, 5.6kg partial size less than or equal to 100nm, which are mixed to obtain, repairs glue.The solidification temperature of the reparation glue
Degree is 60 DEG C, and the shear strength that glue is repaired after solidification is 36Mpa.
Embodiment 2
100kg polyurethane-type anaerobic adhesive, 7.6kg ferrocene, 11.1kg partial size are less than or equal to the Graphene powder of 100nm
Silicon carbide, the 70kg benzene of body, 6.1kg partial size less than or equal to 100nm, which are mixed to obtain, repairs glue.The solidification temperature of the reparation glue
Degree is 66 DEG C, and the shear strength that glue is repaired after solidification is 36.7Mpa.
Embodiment 3
100kg polyurethane-type anaerobic adhesive, 7.9kg ferrocene, 11.5kg partial size are less than or equal to the Graphene powder of 100nm
Silicon carbide, the 80kg benzene of body, 6.3kg partial size less than or equal to 100nm, which are mixed to obtain, repairs glue.The solidification temperature of the reparation glue
Degree is 70 DEG C, and the shear strength that glue is repaired after solidification is 36.3Mpa.
In the above-described embodiments, the shear strength after polyurethane-type anaerobic adhesive directly solidifies is 30Mpa.Graphene powder and
The addition of silicon carbide can reduce the thermal expansion coefficient of the reparation glue, and the addition of silicon carbide, which can also improve, improves the reparation glue
Thermal linear expansion coefficient.The ferrocene can be dissolved in solvent and finally be scattered in polyurethane-type anaerobic adhesive.Polyurethane-type anaerobism
Glue is under oxygen-free environment, room temperature, that is, curable；And by addition ferrocene so that the solidification temperature of the reparation glue promoted to 60~
70 DEG C, the reparation glue is at room temperature even at will not rapid curing under oxygen-free environment.
The mode vacuumized can be used by the inside of leakage hole to being full of, so that it is qualified that reparation can be improved in the reparation glue
Rate.Engine casting cylinder body is using the casting cylinder body of aluminium alloy engine made of die-casting process.Glue-line cuts after the reparation adhesive curing
Shearing stress improves, and the thermal expansion coefficient and thermal linear expansion coefficient of glue-line reduce, so as to significantly improve glue-line and engine
The difference of thermal expansion coefficient between cylinder body is cast, avoids causing the hole wall of glue-line and leakage hole to be detached from because expanding with heat and contract with cold, from
And lead to that secondary gas leakage occurs.Senile experiment, digestion period three are being carried out using the engine casting cylinder body of the reparation glue reparation
Year, leak rate occurs after senile experiment again no more than 2.2%.And common anaerobic adhesive is used, as polyurethane-type anaerobic adhesive is direct
Leakage hole is filled into repair obtained control cylinder body, control cylinder body is 3 years carrying out senile experiment, digestion period, aging
It is more than 6.9% that leak rate occurs after experiment again.That is, the engine casting cylinder body using the reparation glue reparation will not shift to an earlier date
Failure, service life extend.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
