Description
Technical field
The present invention relates to a kind of fluid torque-converter, this torque-converters adopts new corrosion resistant coating spraying; The invention still further relates to a kind of method that adopts stealthy filming agent to spray this torque-converters.
Background technology
Along with the fast development of economy and the hydraulic power extensive use in more areas, society is increasing to the fluid torque-converter demand, also originally higher to its quality requirements equally.
Fluid torque-converter comprises that input guide bracket, tablet, front shroud, turbine, turbine seat, pump impeller, guide wheel, wheel stand and bearing form, the outer wall of input guide bracket, front shroud, pump impeller, wheel stand etc. need to spray the coating of corrosion resistant usually, increase the life-span of torque-converters, the quality of coating quality directly has influence on class and the market competitiveness of product.
At present; China most of fluid torque-converter manufacturing enterprise is paint to the employing of torque-converters surface coating; and face coat requires to have certain fineness, adhesive force, covering power, stain resistance, abrasion resistance, resistance to ag(e)ing, heat resistance, levelability, shorter drying time, suitable MFT etc. as the decoration of component surface protection, metallic element.
There is following defective in paint as common fluid torque-converter surface coating: one, thick coating, drying time are longer; Two, adhesive force is not fine, and depainting phenomenon is often arranged, and affects presentation quality (due to the torque-converters surface imperfection, adhesive force being affected to some extent); Three, cost is relatively high.
Stealthy filming agent is a kind of alcohol radical antirusting paint, not leaded grade is gone back element, can save the front phosphating process of iron and steel spraying and the front anodic process of aluminum products spraying, simplified technological process, energy savings, the figure layer is transparent, pliability is good, strong adhesion, anti-impact force is high, and has excellent oil resistant, heatproof, rustless property, it is a kind of rust conversion that has, not depainting, green environmental friendly coatings that painting cost is low, stealthy filming agent at home, outer multiplex in the shipbuilding field, its antirust and salt fog resistance can reach 1000h, anti-strong acid and highly basic, high temperature resistant 200 ℃.
Stealthy filming agent described above is the stealthy filming agent G201 of matured product on market, stealthy filming agent G201 main component: epoxy resin, ethanol, rosin, phenolic resins, acetone etc.; Production firm: the Jiangnan special metal rust preventing of flood Science and Technology Ltd., phone: 86-532-4121599, fax: 4121599.
Summary of the invention
The present invention will provide a kind of method of stealthy filming agent spraying torque-converters, is mainly used in spraying the stealthy filming agent that the adhesive force grade is high, relative cost is lower, replaces original paint spraying at the stealthy filming agent of fluid torque-converter surface spraying; And prepare according to said method the corrosion resistant fluid torque-converter that coating is thin, the adhesive force grade is high, relative cost is lower.
The invention provides the method at the stealthy filming agent of described fluid torque-converter spraying, comprise the following steps:
A) remove the defective that affects the fluid torque-converter outward appearance, afterwards the face of fluid torque converter face is carried out polishing;
B) with industrial alcohol, the fluid torque-converter surface is cleaned, to its wiping, then entered drying chamber and dry afterwards and with absolute alcohol, bake out temperature is greatly about 35-55 ℃;
C) with alcohol, stealthy filming agent is diluted, volume proportion is 1:1, and is standing after dilution, guarantees to put coating into spray gun after spray coating liquor must not have obvious bubble, uses spray gun to be rotated spraying to the monomer fluid torque-converter;
D) the fluid power device that spraying is good enters into drying chamber dries, and bake out temperature is greatly about 70-85 ℃;
E) complete above step after, first air-cooled 10 minutes, then carried out the cooling 12-24 of nature hour.
Adopt the method for the stealthy filming agent of above-mentioned fluid torque-converter spraying, drying time is relatively short, the adhesive force grade is high, is not easy paint, better appearance, to advantages such as cost are lower.
The described c of the method) in step, the single-piece spraying is adopted in rotation fluid torque-converter spraying, and per minute rotation fluid torque-converter 20-25 turns, the single-piece spray time: 25-30 seconds, can make the stealthy filming agent coating on fluid torque-converter surface thin, spraying is more even.
The invention still further relates to a kind of fluid torque-converter, comprise the fluid torque-converter that the method by the stealthy filming agent of above employing spraying torque-converters directly obtains.
Adopt stealthy filming agent to replace original paint, so should have and have excellent oil resistant, heatproof, rustless property after the stealthy filming agent of this fluid torque-converter spraying, have rust and transform, the advantage such as low, the environmental protection of depainting, painting cost not.
The specific embodiment
Below in conjunction with specific embodiment simulation fluid torque-converter surface in working order, come the fluid torque-converter advantage to the common paint spraying of fluid torque-converter contrast of the present invention, be described further.
Test one: salt spray test:
Test objective: this time test is in order to verify the salt spray corrosion resistance of 2 models (each of recessive overlay film, paint).
The test exemplar: stealthy overlay film salt mist experiment model numbering and the corresponding thickness measurement data of diverse location, 211# is stealthy filming agent model (spray solution of stealthy filming agent and alcoholic solution concentration ratio are 1:1); 217# is the paint spraying model, as following table:
Result of the test such as following table:
The corrosion resistance of recessive overlay film is better than paint (the problems referred to above does not appear in X representative as can be seen from the test results; √ represents to occur the problems referred to above).
Test two: heatproof test
Testing equipment: Constant Temp. Oven, overlay film calibrator, automatic temperature measurement instrument, mercury temperature stopwatch.
Test method and flow process: 1, test sample plate overlay film thickness under room temperature condition; 2, put the electrical heating case into and be heated to 110 ℃, and be incubated 15 minutes; 3, take out, observe change color and touch perception and whether glue hand; 4, be cooled to room temperature, observe change color, touch and the detect thickness variation; 5, put the electrical heating case into and be heated to 120 ℃, and be incubated 15 minutes; 6, take out, observe change color and touch perception and whether glue hand; 7, be cooled to room temperature, observe change color, touch and the detect thickness variation; 8, off-test.
Conclusion (of pressure testing): the heat resistance of paint far is worse than recessive filming agent coating, and recessive filming agent coating can be used under 120 ℃ for a long time, satisfies the instructions for use of fluid torque-converter fully.
Test three: heat dispersion test test method and flow process: two models are put into Constant Temp. Oven be heated, during to uniform temperature, taking-up is placed under same environment, interval three times difference meter surface temperature.
Result: the data from form can draw recessive overlay film heat dispersion and be better than paint.
In sum, at the stealthy filming agent of fluid torque-converter surface spraying of the present invention, replace original paint spraying to meet the requirement of torque-converters under regular service conditions fully, and contrast original paint spraying and on salt fog resistance corrosion and temperature resistant capability, significant progress is arranged.
Common paint on torque-converters and the stealthy filming agent of being sprayed on forms and is very different, so the method for spray paint is difficult to be applicable to spray filming agent.
