Abstract
The invention discloses a kind of New Kind of Anti-Carburizing Paint, are formulated by 15% boric acid of component, 8% titanium dioxide, 6% lithium bentonite, 5% chrome yellow, 3% maleic acid, 4% lotus root starch, 5% sodium benzoate, 3% polyethers, 3% potassium chloride, 2% paraffin, 3% mesotrione, 0.5% sodium hydroxide, 2% zinc chloride, 2% ferrous sulfate and the excess water of following mass percent.The masking paste of the present invention can be removed after carburizing heat treatment by washing, to solve the problems, such as that traditional masking paste is difficult to remove after carburizing heat treatment, use inorganic refractory materials as anti-carburizer in the masking paste formula of the present invention, the anti-carburization coating caking property that anti-carburizer brushing of the present invention is formed after workpiece surface is good, and at high temperature non-scale, do not trickle, do not influence carburizing atmosphere.
Description
Technical field
The present invention relates to a kind of masking pastes.
Background technology
The component of machine such as gear generally require after machining carries out Carburization Treatment to its working face or stress surface, so
After carry out quenching or other heat treatment, to improve its mechanical performance, chemical property and processing performance.In order to allow subsequent handling to carry out
The surface of secondary operation does not generate brittle property and damages process tool, needs locally to carry out anti-carburizi ng to workpiece surface in carburizing
Processing.The anti-carburizi ng method of steel-iron components mainly has mechanical processing method, copper-plating method and masking paste method.Mechanical processing method is logical
The allowance for improving workpiece is crossed, removes carburized layer by modes such as machinings after carburizing and heat treatment.This method
Material is not only wasted, process is also added, the cost of charp tool also increases, and is gradually replaced by copper-plating method and masking paste method.
Copper-plating method is most traditional anti-seepage method, and antiseepage quality is high.But this method belongs to chemical method, it is of high cost, the period is long, and
Plating solution seriously pollutes environment.Masking paste method is not need the surface coating one of antiseepage in workpiece before carrying out Carburization Treatment
Coating is protected, again by coating removal after carburizing and heat treatment.General impermeable coating is mainly with silicate, glass powder
Film forming matter, this kind of coating are difficult stripping after carburizing and heat treatment, need to remove by ball blast or blasting treatment, increase life
Cost is produced, the production cycle is extended.In addition for labyrinth workpiece, the masking paste of inside workpiece brushing is extremely difficult
It is removed by ball blast or sandblasting.
Chinese patent CN1184831A is disclosed a kind of first brushing one layer of scavenger layer before workpiece brushing masking paste
Method, by the technique, the coating of workpiece surface can be peeled off voluntarily after workpiece high-temperature heating.But the technique can lead to workpiece
The coating on surface is just fallen off in carburizing process, is oozed so as to cause leakage, and anti-seepage effect is reduced.Chinese patent
CN101074455A discloses water self-stripping protective coating, and this coating can voluntarily be peeled off by washing.But as this
The water-base resin of kind coating main component belongs to the organic matter of non-refractory, can decompose in carburizing process, interferes carburizing
Atmosphere, to influence carburizing quality.Therefore a kind of high temperature when non-scale, do not trickle, do not influence carburizing atmosphere, and at carburizing heat
It can be necessary by washing the exploitation of the masking paste of removal after reason.
Invention content
Goal of the invention：Technical problem to be solved by the invention is to provide a kind of paintings of the anti-carburizi ng of washable removal after quenching
Material, the masking paste is good to the adhesive force of iron and steel parts, fast from dry speed, and brushing can ensure it certainly in workpiece surface
Body at high temperature non-scale, do not trickle, do not influence carburizing atmosphere, and can also pass through after carburizing heat treatment and wash removal.
Invention content：In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of New Kind of Anti-Carburizing Paint,：By 15% boric acid of component, 8% titanium dioxide, 6% lithium base of following mass percent
Bentonite, 5% chrome yellow, 3% maleic acid, 4% lotus root starch, 5% sodium benzoate, 3% polyethers, 3% potassium chloride, 2% paraffin,
3% mesotrione, 0.5% sodium hydroxide, 2% zinc chloride, 2% ferrous sulfate and excess water are formulated.
Advantageous effect：The masking paste of the present invention can be removed after carburizing heat treatment by washing, to solve
The problem of traditional masking paste is difficult to remove after carburizing heat treatment, masking paste of the invention use inorganic resistance in being formulated
For high-temperature material as anti-carburizer, the anti-carburization coating caking property that anti-carburizer brushing of the present invention is formed after workpiece surface is good,
And at high temperature non-scale, do not trickle, do not influence carburizing atmosphere.
Specific implementation mode
According to following embodiments, the present invention may be better understood.However, as it will be easily appreciated by one skilled in the art that real
It applies content described in example and is merely to illustrate the present invention, without sheet described in detail in claims should will not be limited
Invention.
Embodiment 1：
A kind of New Kind of Anti-Carburizing Paint, it is swollen by 15% boric acid of component, 8% titanium dioxide, 6% lithium base of following mass percent
Moisten soil, 5% chrome yellow, 3% maleic acid, 4% lotus root starch, 5% sodium benzoate, 3% polyethers, 3% potassium chloride, 2% paraffin, 3%
Mesotrione, 0.5% sodium hydroxide, 2% zinc chloride, 2% ferrous sulfate and excess water are formulated.
The gear for being 20CrNi2Mo to material with the masking paste of embodiment 1 carries out anti-carburizi ng processing, and carburization process is
940 DEG C of heating 110h, carburized layer depth 4.1-4.8mm, direct quenching after carburizing, quenched workpiece impregnates 3h in 50 DEG C of water
Afterwards, the anti-carburization coating of workpiece surface is completely peeled off.It, can since the masking paste of embodiment 1 has good anti-seepage effect
Effectively carbon atom is prevented to penetrate into workpiece surface, so workpiece surface is no in carburizing atmosphere to generate carburized layer, then quenched time
The metallographic structure of workpiece surface is low-carbon martensite as workpiece core after fire.
Obviously, the above embodiment is merely an example for clearly illustrating the present invention, and is not to the present invention
The restriction of embodiment.For those of ordinary skill in the art, it can also be made on the basis of the above description
Its various forms of variation or variation.There is no necessity and possibility to exhaust all the enbodiments.And these belong to this hair
The obvious changes or variations that bright spirit is extended out are still in the protection scope of this invention.
