Description
Technical field
The present invention relates to the coating that the present invention relates to the indoor and outdoor heating service that can be used for building, can be made into Electric heating table, electric heater and industrial middle low-temperature bake electric furnace, specially electric-heating coatings.
Background technology
Several electric-heating coatings patents are disclosed currently on the market（Publication number CN1068582, CN1112592）, they are mainly using carbon dust and graphite as filler, the problem is that the resistance of these electric-heating coatings is all at tens ohm or more, if further increasing conductive filler content resistance, then the adhesive force of coating is deteriorated, and heating efficiency is relatively low in actual use, needs higher voltage（Higher than 36 volt-amperes full voltages）, it is unfavorable for practical application.
Invention content
Regarding to the issue above, the present invention provides a kind of electric-heating coatings, it is coated on indoor wall, at the sentry post on desk, outdoor, heating service can be realized in voltage safe to use, by the control of resistivity, meet different heating requirements, 5 DEG C~20 DEG C of performance higher than environment temperature can be reached, for this purpose, the present invention also provides the processing methods of electric-heating coatings.
Its technical solution is such：It includes following weight parts material：40 parts ~ 60 parts of film forming matter, 15 parts ~ 30 parts of color stuffing, 1 part ~ 2 parts of auxiliary agent, 20 parts ~ 30 parts of solvent, above-mentioned substance is put into ball mill in proportion, is adequately mixed, is ground, and the coating of 30 μm ~ 60 μm of fineness range is made.
The film forming matter is acrylic resin, epoxy resin or polyurethane resin；
The color stuffing is 10%~30% silver medal containing weight percentage including 5 parts~15 parts Ni powder, 10 parts~20 parts silver-coated copper powders；
The auxiliary agent includes adhesion promoter Silok629, and content accounts for film forming matter 0.5%~1% and dispersant Efka4010, and content accounts for pigment 0.5%~1%；
It is described that different solvents, including polystyrene, toluene, butyl acetate, cyclohexanone etc. are selected according to different film forming matters；
The corresponding diluent of the acrylic resin include following volumes than material：Butyl acetate 20：Dimethylbenzene 60：Cyclohexanone 20；
The corresponding diluent of the epoxy resin include following volumes than material
：Butyl acetate 40：Butanone 40：Cyclohexanone 20；
The corresponding diluent of the polyurethane resin include following volumes than material：Butyl acetate 25：Dimethylbenzene 60：Cyclohexanone 15.
Select wicker copper as conductive filler, it improves the electric conductivity of copper powder, reduces the cost of silver powder, and solves the problems, such as that copper powder is oxidized easily, therefore coating can be made to reach lower resistivity（Electrical resistivity range:M~1 0.1 × 10-4 Ω × 10-4 Ω m）, and suitable for engineering production.Prepared electric-heating coatings ensure that coating can be coated in different substrates, while crossing the preferred of adjuvant system and solving the problems, such as coating adhesion well by different film forming matters.Since conductivity is relatively low and can adjust, different resistance can be reached by the adjustment of different length and widths, thickness.Such as in 20cm × 30cm, thickness 0.15mm
Coating resistance can reach 1~5 Ω, therefore in safe voltage（36 volts）There is down good heating effect.
