Description
Technical field
The present invention relates to a kind of thermohardening type organic impregnating agent, and in particular to a kind of water-soluble organic impregnating agent.
Background technology
It casts parts and powder sintered parts in process of production, micropore or gap, such as needle inevitably occurs
The product defects such as hole, stomata, loose, for ratio of defects according to the shape of product, thickness, size and difference, ratio of defects is 6~100%.
For the product for having air-tightness to require, after machining, when pressure test, finds that leakage can only then scrap, to cause people
The waste of work, raw material, the energy etc..The product that no air-tightness requires is in surface treatments such as plating, spraying, plastic-sprayings, because of cleaning
The media such as agent, acid solution enter hole, lead to internal corrosion, shorten the working life, or because the presence of micropore makes process of surface treatment
There is bubble or uneven phenomenon, leads to product quality defect.To handle problems, infiltration is needed to handle, in certain item
Impregnant is penetrated into the micropore of casting under part, and so that impregnant is polymerize in hole by heating and forms colloid, to
It is filled with the hole of parts.
Mainly there are silicic acid sodium form impregnant, the agent of acrylic ester type organic impregnating and resin type using extensive impregnant at present
Impregnant three categories.Inorganic impregnant is a kind of impregnant used earliest, there is that of low cost, heat resistance is strong, but
Its viscosity is high, wellability is poor, infiltration qualification rate is low, is just gradually replaced by acrylic ester type impregnant.Resin type impregnant
Due to viscosity is excessive, need be added diluent be diluted, in diluent many be more toxic it is higher with volatility
Compound, detrimental effect is all brought to environmental protection and safety, infiltration yield rate, thus just gradually by acrylic ester type impregnant
Replaced.Acrylic ester type impregnant is not because have the shortcomings that silicic acid sodium form and resin type impregnant, gradually instead of other classes
The impregnant of type is the current a kind of impregnant for most having application prospect, and acrylic ester type impregnant forms substantially to be mainly included
Functional form acrylate monomer, acrylate oligomer, initiator, polymerization inhibitor, anti-shrink ingredient, emulsifier, chelating agent etc..Third
Olefin(e) acid ester type impregnant advantage is not shunk after acrylic ester type impregnant cures in hole, it is possible to fully plugging hole
Gap infiltrates success rate highest, the another tolerance under the various physical and chemical conditions such as irreversible, heat-resisting, solvent resistant after solidification.
The major defect of acrylic ester type impregnant at present：Acrylic ester type impregnant is because be not completely soluble in water, institute
It cannot be met with its washing performance and infiltrate each parts, so impregnation step or more complicated cumbersome.It is in particular in,
The parts to be infiltrated have a threaded hole not of uniform size, even only remaining seldom impregnant in cleaning rear thread hole,
Impregnant in cured process in threaded hole can also become solidfied material, occur spiral shell in assembly process to the user of parts
Silk is twisted not tightly, and painstakingly, threaded hole problems of crack, client does not receive have solidfied material in threaded hole.
Impregnation step is as follows：
Workpiece is packed into hanging basket → latching hanging basket lid → vacuum infiltration → centrifugal drying liquid → cleaning 1 → cleaning 2 → opening and hangs
Basket lid → take out workpiece → air gun aiming blows threaded hole → workpiece and reloads hanging basket → locks hanging basket lid → repetitions clearly again
Wash 1 → repeated washing, 2 → water cure.Handle every basket of workpiece and need 120 minutes * 2 people, thus impregnation step it is very complicated, it is time-consuming,
Wasting manpower and material resources, although process is so complicated, deeper threaded hole still has solidfied material, can only check each by hand
Threaded hole, then solidfied material is removed in tapping by hand, checks and cleaning threaded hole needs 60 minutes * 1 people, serious waste people again
Power.
Invention content
The present invention solves the technical problem of：One kind is provided for closing porous material, is mainly used to sealing casting
The complete water-soluble thermohardening type organic impregnating agent of forging piece and powdered metal parts micropore.
To solve the above-mentioned problems, the technical scheme is that：A kind of water-soluble organic impregnating agent, by mass percentage
Meter, component include：
The initiator, preferred mass percentage are 0.2-0.6%.
The single functionality methacrylate monomers are selected from one or more of following substances：Methacrylic acid third
Ester, methyl methacrylate, butyl methacrylate, Isobutyl methacrylate.
The bifunctionality methacrylate oligomer is Epocryl and/or neopentyl glycol dimethyl
Acrylate.
The reactive emulsifier is alkyl phenol polyoxyethylene ether.
The initiator is selected from one or more of following substances：Azodiisobutyronitrile, sodium peroxide, azo two are different
Heptonitrile.
The diethanol amine and/or triethanolamine makes impregnant not soluble in water be modified with ethyl acetate collective effect,
Become completely soluble.
Beneficial effects of the present invention：Product disclosed in the present application is completely soluble organic impregnating in a liquid state
Agent, it is easy to clean, acrylic ester type impregnant is also belonged to, is equally had and is not shunk after curing, can fully block hole, leaching
Ooze that success rate is high, the tolerance after solidification under the various physical and chemical conditions such as irreversible, heat-resisting, solvent resistant.
This product advantage：The threaded hole of workpiece is rinsed without expending huge manpower and materials, after impregnant solidification, workpiece
Threaded hole in do not have removing residual glue shape solidfied material, will not more block threaded hole.Infiltration manufacturing procedure is set to become simple.
The success rate 100% of workpiece is sealed, it is low to the dependency degree of Impregnation apparatus, either compared with large micropore or minimum micropore
Casting and powder metallurgy parts be all ideal impregnant.
Improvement is：The complete water-soluble organic impregnating agent can be completely soluble.Because its is completely soluble, so
The cleaning performance of acrylate impregnant is improved, impregnation step is reduced to：Workpiece loading hanging basket → latching hanging basket lid → true
Empty infiltration → centrifugal drying liquid → cleaning 1 → 2 → water cure of cleaning.As long as handling 20 minutes * 1 people of every basket of workpiece.After simplification
Impregnation step reduces the process much infiltrated, has saved the time, reduces personnel.The process of reduction has：Opening hanging basket lid,
Take out workpiece, air gun aiming blow threaded hole, workpiece reloads hanging basket, locks hanging basket lid again, repeated washing 1, repeated washing
2.The infiltration time reduces 100 minutes, and personnel reduce 50%.And without checking in threaded hole and tapping removal threaded hole
Solidfied material, and reduce 60 minutes * 1 people.Infiltration efficiency is set to have matter leap.
