Description
Technical field
The invention belongs to technical field of coatings, relate to a kind of IR thermal imaging inspection water-soluble black coating.
Background technology
In IR thermal imaging inspection, utilizing visible ray to carry out heating is a kind of conventional mode.Because measured surface color is different or degree of roughness is different or the reflective strong or material in metallic surface has the reasons such as obvious light transmission to visible ray, when causing heating there is the uneven or underheating phenomenon of significantly heating in measured surface, and then have impact on the accurate judgement to detected result.For this problem, need the optical characteristics improving measured surface, improve the uniformity consistency of specific absorption to visible ray and absorption; In addition because infrared detection is determined the method for measured surface temperature variation, the infrared emittance and the consistence thereof that therefore improve measured surface are also very important; If lead-covering sandwich structure piece is the large class material often run in IR thermal imaging inspection, because aluminium surface ratio is brighter, when heating component surface with photoflash lamp, visible ray is reflected in a large number, and then have impact on heats; And for example silica fiber laminate has certain light transmission to visible ray, and the IR thermal imaging inspection of this character to this series products is disadvantageous.
Summary of the invention
The object of the invention is to propose a kind of base material for various state to need to develop a kind of high IR emittance water soluble paint, to improve the infrared temperature feature on detected material surface, heat forming uniform visible ray at body surface, thus the accurate judgement reached infrared imaging detected result, improve a kind of IR thermal imaging inspection water-soluble black coating of infrared imaging Detection results.
The object of the invention is to be achieved through the following technical solutions:
This material, using water-soluble binder as matrix, adds black filler, thickening material, sanitas and thinner and is composited; Wherein,
The massfraction of water-soluble binder is 3% ~ 30%, and water-soluble binder comprises polyvinyl alcohol water solution or epoxy resin latex or polyaminoester emulsion or the mashed prod through the starch-containing class food crop of boiling water furnishing, and solid content is 25%;
The massfraction of black filler is 10% ~ 40%, and black filler is Shawinigan black;
The massfraction of thickening material is 0.5% ~ 5%, and thickening material is water-borne coatings thickening material;
Sanitas is inorganic salt or organic alcohols solvent or ammoniacal liquor, wherein, if use its amount mark of inorganic salt to be 1%-10%; If use its massfraction of organic alcoholic solvent to be 10%-60%; If working concentration is the ammoniacal liquor of 2%-17%, its massfraction is 5%-20%;
The massfraction of thinner is 10%-60%, and thinner is deionized water or distilled water or tap water;
Above-mentioned water-soluble binder, black filler, thickening material, sanitas, thinner are weighed respectively, then to be composited a kind of uniform aqueous suspension by dispersed with stirring equipment, matrix material or metallic surface film forming is coated in again by brushing, spraying method, for measuring use after drying, can directly with water flushing, scrub after measurement.
The advantage that the present invention has and beneficial effect are:
The water-soluble black coating of the present invention's development has high IR emittance feature.Be sprayed at after detecting surface, have excellent adsorptivity, filler particles is little and even, the paint film uniformity that spraying obtains, the film coating of sub-light feature can be formed at substrate surface, under the irradiation of visible ray, strong uniform pickup ability is formed to visible luminous energy, homogeneous heating effect can be significantly improved, thus very active effect is produced to Detection results, achieve the reliability that infrared imaging detects, and this coating is soluble in water, is convenient to remove from measured surface after detection completes; Measured material is not damaged, the feature such as harmless.
