Abstract
The invention discloses welding rod lettering pigment, belong to hard fire colour technical field, this welding rod lettering pigment is mainly uniformly mixed by dispersion agent, high-temperature resisting pigment, solidifying agent and dilution material and makes.This pigment resistance to elevated temperatures is good, and physical and chemical performance is stablized, and long-time placement precipitation-free demixing phenomenon (or only have slight demixing phenomenon, stir before using), and raw materials cost is lower.
Description
Technical field
The invention belongs to high-temperature resisting pigment technical field, be specifically related to welding rod lettering pigment and preparation method thereof.
Background technology
Along with the continuous enhancing of environmental protection and energy saving synergy consciousness, do not reduce the prerequisite decline low production cost of quality product, and want raw material drawing conveniently to become trend of the times.
Welding rod lettering pigment adopted pigment dyestuff in the past, and pigment dyestuff, compared with general mineral dye, has higher tinting strength usually, and particle easily grinds and disperses, not easily precipitates, and color is also more bright-coloured, but sun-proof, heat-resisting, weather resistance is poor; And need outwards buying to be specifically designed to the organic synthesis thing starting material making pigment, and the welding rod that welder's life-time service is printed on this pigment also can cause certain harm to Occupational health.
Summary of the invention
The technical problem to be solved in the present invention is to provide provides a kind of low cost, the resistant to elevated temperatures welding rod lettering pigment not containing organic synthesis material, this pigment is imprinted on welding rod, there is high temperature when resistance to welding rod cures, scratch resistance, weather-proof, and raw material drawing is convenient, adopt the raw material that welding rod is produced, cost is lower.
For achieving the above object, technical scheme of the present invention is as follows:
Welding rod lettering pigment, according to mass parts meter, comprises following component: dispersion agent 7-10 part, high-temperature resisting pigment 10-15 part, solidifying agent 5-8 part, dilution material 75-85 part.
In a preferred embodiment of the invention, described dispersion agent is calcium-base bentonite.
In a preferred embodiment of the invention, described high-temperature resisting pigment adopts the iron oxide black of one of component identical with welding rod.
In a preferred embodiment of the invention, described solidifying agent is the one in Powdered water glass or pure potash water glass.
In a preferred embodiment of the invention, described pure potash water glass is 3.3M, the pure potash water glass of 38 ° of Be '.
In a preferred embodiment of the invention, described dilution material for mass percent be one in the aqueous sodium hydroxide solution of 1%-3% or potassium hydroxide aqueous solution.
The preparation method of welding rod lettering pigment, comprises the following steps:
First according to respective mass parts: dispersion agent 7-10 part, high-temperature resisting pigment 10-15 part, after solidifying agent 5-8 part and dilution material 75-85 part take;
Then dispersion agent, high-temperature resisting pigment, solidifying agent are mixed, then add in dilution material, fully mix, stir formation mixture;
Finally mixture is put into colloidal mill grinding, obtain pulpous state black pigment.
By technique scheme, the invention has the beneficial effects as follows:
This high-temperature resisting pigment raw material has drawn from the starting material that welding rod is produced, and be used for welding rod lettering, draw materials conveniently, preparation is simple, with low cost; And resistance to elevated temperatures is good, physical and chemical performance is stablized, and long-time placement precipitation-free demixing phenomenon (or only have slight demixing phenomenon, stir before using).
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further.
Welding rod lettering pigment, according to mass parts meter, comprises following component: dispersion agent 7-10 part, high-temperature resisting pigment 10-15 part, solidifying agent 5-8 part, dilution material 75-85 part.
Above-mentioned dispersion agent is high purity calcium-base bentonite (AA type), and AA type calcium-base bentonite water-retaining capacity is strong, has good suspended dispersed effect;
Above-mentioned high-temperature resisting pigment adopts the iron oxide black of one of component identical with welding rod, and chemical formula is Fe3O4.
Above-mentioned solidifying agent is Powdered water glass (being commonly called as sodium silicate) or pure potash water glass (3.3M, 38 ° of Be '), and this solidifying agent can significantly improve pigment and be imprinted on firmness on welding rod after high bake temperature.
Aqueous sodium hydroxide solution or the potassium hydroxide aqueous solution of above-mentioned dilution material to be mass percent be 1%-3%.The effect of dilution material is the viscosity reducing mixture, obtains good mobility.
Embodiment 1
Weigh by following each raw material:
After above-mentioned raw materials takes, first AA type calcium-base bentonite, iron oxide black, powder water glass are mixed, 1% aqueous sodium hydroxide solution adding 11kg, as dilution material, fully mixes, stirs.Then mixture is put into colloidal mill grinding, obtain pulpous state black pigment, there is certain mobility.
The temperature of core wire and coating when this pigment meets welding rod stoving temperature when concrete use, welding rod burns tail end, when testing established temperature and reaching 800 DEG C, after welding rod cured through 2 hours, lettering is still high-visible, without variable color, scratch resistance.
Embodiment 2
Weigh by following each raw material:
After above-mentioned raw materials takes, first AA type calcium-base bentonite, iron oxide black dry mixing are mixed, then pour the pure potash water glass (3.3M, 38 ° of Be ') of 2kg and 1% aqueous sodium hydroxide solution of 9kg into, fully mix, stir.Then mixture is put into colloidal mill grinding, obtain pulpous state black pigment, there is certain mobility.
The temperature of core wire and coating when this pigment meets welding rod stoving temperature when concrete use, welding rod burns tail end, when testing established temperature and reaching 800 DEG C, after welding rod cured through 2 hours, lettering is still high-visible, without variable color, scratch resistance.
Embodiment 3
Weigh by following each raw material:
After above-mentioned raw materials takes, first AA type calcium-base bentonite, iron oxide black dry mixing are mixed, then pour the pure potash water glass (3.3M, 38 ° of Be ') of 2kg and 1% aqueous sodium hydroxide solution of 9kg into, fully mix, stir.Then mixture is put into colloidal mill grinding, obtain pulpous state black pigment, there is certain mobility.
The temperature of core wire and coating when this pigment meets welding rod stoving temperature when concrete use, welding rod burns tail end, when testing established temperature and reaching 800 DEG C, after welding rod cured through 2 hours, lettering is still high-visible, without variable color, scratch resistance; And existing lettering pigment in this case, there will be the phenomenons such as font is fuzzy.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
