Abstract
The invention discloses a kind of matching method that is applied to the inorganic impregnate liquid on the foundry goods.By the infiltration liquid of this square one-tenth and the characteristics of foundry goods micropore effect be, it is withstand voltage to make the foundry goods micropore reach sealing, can work in-70 ℃～+ 8 20 ℃ of scopes, is not afraid of vibration, and anti-machine oil, diesel oil are not afraid of boiling water, bear pressure and are not less than 20kg/cm
2This infiltration liquid micro-pore diameter that can infiltrate is less than or equal on the cast aluminium, cast iron, cast copper, cast steel and the metallurgical part of powder of 0.4mm, and nontoxic.The experiment proved that and be better than known infiltration liquid.
Description
The present invention relates to a kind of matching method that is applied to the inorganic impregnate liquid of casting impregnation.
In the Foundry Production of mechanical industry, because the influence of various factors in starting material and the production inevitably produces some micropores on foundry goods, to making foundry goods infiltration, oil impregnate, gas leakage.For solving this difficult problem, corresponding impregnation technology is adopted in countries in the world, and the how crucial matching method of infiltration liquid and the processing method of infiltration of being of infiltration effect.
After domestic existing infiltration liquid and foundry goods fully acted on curing at present, its hot water resistance was relatively poor, and when temperature reached 37 ℃, impregnating material just began fusing, is cotton-shaped.The infiltration liquid that has is interim curing, and oil-proofness is relatively poor.With regard to existing in the world infiltration liquid organic substance known to the contriver form more, though water tolerance is better, high thermal resistance is relatively poor.For studying this problem, the contriver utilizes U.S. DIALOG system to retrieve the document World Patent Index No. 351, and No. 32 documents " U.S.'s metal digest ", No. 14 documents " mechanical engineering " all do not find with the present invention pertinent literature is arranged.(asking for an interview " international online information retrieval proof is single ")
Main task of the present invention is, for solving sealing foundry goods micropore, proposes a kind of new infiltration liquid, is used to the foundry goods that infiltrates, and realizes the foundry goods that infiltrate in oily, gas heatproof in the boiling water Working environment particularly, and is withstand voltage.
The present invention proposes is applied to inorganic impregnate liquid on the foundry goods, is made up of routine material down:
Lithium silicate 70～71%(weight)
Water glass 27～28%(weight)
Ferric oxide 0.4～0.5%(weight)
Aluminum oxide 0.9～1%(weight)
Vanadium Pentoxide in FLAKES 0.25～0.3%(weight)
Calcium oxide+zinc oxide 0.03～0.05(weight)
Sodium laurylsulfonate 0.009～0.01%(weight)
Wherein lithium silicate is a water soluble industrial lithium metasilicate, modulus M=4.8; PH11～11.5 proportions are 1.18～1.19; Water glass is an industrial metasilicate, modulus M 〉=3.0; Proportion is 1.4g/Cm
3
According to above-mentioned substance component proportioning, mix to stir and to finish task proposed by the invention.Having surperficial tension according to this formed infiltration liquid of filling a prescription is 45～57dyn/Cm; Proportion is 1.27～1.29g/Cm
3Viscosity factor 1.95 pools; PH11～11.5.
The present invention has following characteristics:
1, resistance to boiling water is good, and this infiltration liquid can be stabilized in the boiling water and work after fully acting on foundry goods.Through to soaked foundry goods repeatedly the boiling water resistance to boiling water that boils this infiltration liquid of evidence be better than the infiltration liquid that Japan three builds company.
2, fully to act on the operating temperature range after the curing be-70 ℃～+ 820 ℃ for this infiltration liquid and foundry goods.
3, this infiltration liquid strong adhesion, anti-vibration.Through the 140 horsepower diesel cylinder cap entruckings test in 500 hours of being infiltrated is not found to leak.
4, oil-proofness is good.Through the impregnated foundry goods of this infiltration liquid, can in diesel oil, machine oil environment, work.
5, this infiltration liquid maximum diameter of hole of can infiltrating is to be less than or equal to 0.4mm.
6, infiltrated casting section thickness greater than 1mm.
7, this infiltration liquid is sorrel, non-volatile, nontoxic.
8, this infiltration liquid is applicable to cast iron, cast aluminium, cast steel, cast copper and metallic sintered products.
For demonstrating fully characteristics of the present invention, existing with following embodiment explanation.
The compound method of example 1, infiltration liquid:
1, at room temperature with modulus more than or equal to 3.0, proportion is 1.4g/Cm
3Sodium silicate solution put into according to weight percent that to fill modulus be 4.8, proportion is 1.1～1.19(g/Cm
3) the molten device of lithium silicate solution in, stir.
2, respectively powdery ferric oxide, aluminum oxide, Vanadium Pentoxide in FLAKES, calcium oxide ten zinc oxide are put into the mixing solutions of lithium silicate and water glass according to weight percent, continued to stir.
3, with+50 ℃ of hot water sodium laurylsulfonate dissolving back is added in the above-mentioned solution, stir, promptly make this infiltration liquid.
Example 2, this infiltration liquid acts on best results with the foundry goods that infiltrated in vacuum pressed equipment.Specific embodiment is as follows:
1, cleans.Use+80 ℃ 0.2% metal cleaner to clean up with desiring to soak part, dry under+80 ℃～100 ℃ temperature afterwards.
2, vacuum pressed.Soaked part and put into vacuum apparatus dried, vacuumize, negative pressure is not less than the 700mm mercury column, and pressurize is opened the container for storing liquid valve and sucked infiltration liquid after 10 minutes, (the infiltration liquid temperature is generally at 20 ℃ to 40 ℃) close the container for storing liquid valve again, pressurization 5～6.5kg/Cm
2, 20～30 minutes, infiltration finished, and emitted after the liquid, cleaned with 35 ℃～40 ℃ warm water and was soaked part.
3, solidify.To soak part puts into loft drier and is cured.Solidification value is not less than 150 ℃, and the time is no less than 30 minutes.
4, the part that will infiltrate is at last cleaned out.
