Description
The present invention relates to a method for manufacturing an aluminum surface material for thermal insulation used mainly for building insulation and an aluminum surface material, and more particularly, to a method for improving the function of a coating layer formed on an aluminum surface material.
Generally, in the case of thermal insulation of thermal insulation due to thermal conduction among various building insulation materials, a film type surface material made of aluminum is adhered to the upper and lower sides of the thermal insulation material having an inner air layer to effectively block heat transfer by radiation heat, And the heat insulating material having such a function has already been disclosed in Korean Patent No. 10-1521474 'Heat Insulation Material with Improved Heat Insulation Property' and 'Heat Insulation Material with Improved Heat Insulation Property' of Japanese Patent No. 10-1558953.
In addition, since the aluminum surface material constituting such an insulating material has a deteriorated function and a shortened lifetime due to corrosion and oxidation when exposed for a long period of time, it has been proposed to form a coating layer on the surface material in order to prevent corrosion and oxidation of the aluminum surface material. There has also been provided an " aluminum surface material for insulating material and a manufacturing method thereof ".
However, Japanese Patent Application No. 10-1528156 discloses a method for coating a surface of an aluminum surface material by coating a coating solution prepared by mixing two or more main resin compositions, various additives, an adhesive reinforcing agent and a solvent, The coating solution is formed to be transparent in order to maintain the surface emissivity of the surface material, and it is difficult to identify the coated surface during the coating operation due to transparency, so that the primary coating and the secondary coating and drying are performed for quality control. And the coating layer is transparent. Therefore, even after the coating process, the surface of the aluminum material is glazed due to the reflection of light inherent to the aluminum surface material, resulting in difficulty in handling and construction. Particularly, As it is difficult to differentiate from the products, reliability of the superiority of coating products There is a problem that it is difficult to set a price including a coating cost as well as a falling price.
It is an object of the present invention to simplify the coating process and to prevent glare caused by light reflection while satisfying basic functions required for prevention of corrosion and oxidation of the surface material during coating, And a method for manufacturing an aluminum surface material for a heat insulating material which can easily be visually recognized whether or not a coating is formed, and an aluminum surface material thereof.
In order to accomplish the above object, the present invention provides a method for producing an aluminum surface material for an insulation material and an aluminum surface material thereof, which comprises mixing a main resin composition, an adhesive reinforcing agent, an additive and a colored organic pigment to obtain a colored coating solution Next, the coating solution is coated on the surface of the aluminum surface material and dried to form a colored coating layer on the surface of the aluminum surface material.
The aluminum surface material obtained by the present invention has a coating layer coated on the surface of the aluminum surface material to satisfy the basic function for preventing corrosion and oxidation while the coating material is coated with the blue colored organic pigment contained in the coating solution, Since it can be easily visually confirmed, it is possible to improve the productivity by coating the entire coating without the uncoated part even if only one coating is applied. In addition, the blue-based colored organic pigment distributed throughout the coating layer prevents the reflection of light inherent to the aluminum surface material, In particular, it is possible to visually recognize whether the aluminum surface material is coated due to the blue colored organic pigments of the coating layer, so that it is possible to increase the reliability of the users of the coating product There It will be effective, such that.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. do.
The present invention relates to a resin composition comprising a solid content obtained by mixing 73.0 to 90.0% by weight of a main resin composition, 1.0 to 10.0% by weight of an adhesive reinforcing agent, 0.1 to 3.0% by weight of an additive and 3.0 to 15.0% by weight of a colored organic pigment with 20.0 to 50.0: 50.0 To 80.0% by weight to obtain a colored coating solution, coating the surface of the aluminum coating material on the surface of the aluminum coating material, and drying the coating material to form a colored coating layer on the surface of the aluminum coating material.
As the main resin composition in the solid content, polyester, polyamide, polyurethane, acrylic, cellulose, vinyl chloride and epoxy are used alone or in a mixture of two or more.
Of the components constituting the main resin composition, polyethylene terephthalate (PET) is exemplified as the polyester-based resin, but since it is low in solubility in solvents and too high in crystallinity of the resin, it is not suitable for use alone, Can be produced by copolymerizing an acid component constituting the polyester resin with a component having a strong amorphous characteristic such as an aliphatic or alicyclic group and the like and copolymerizing the glycol component with a component capable of lowering the storage transition temperature of the polyester resin. , Isophthalic acid or a lower alkyl ester thereof, and an aliphatic dicarboxylic acid having 6 to 12 carbon atoms which may be represented by HOOC- (CH 2 ) n-COOH or a lower alkyl ester thereof Or a mixture thereof, and the glycol component Any one selected from the group consisting of ethylene glycol, 1,6-hexanediol, 1,4-butanediol, 1,2 or 1,3-propylene glycol, neopentyl glycol, polyether polyol and polyester polyol, Is used.
As polyamide-based resins, there may be mentioned polyamide-6 structures made of ε-caprolactam or ε-aminocaproic acid, polyamide-12 components capable of being prepared from aminododecanoic acid or lauryllactam and hexamethylene adipate Or a resin component in which a polyether polyol is copolymerized is used.
Examples of the polyurethane resin include diisocyanates such as toluene diisocyanate and diphenylmethane diisocyanate, polyol components such as ethylene glycol, propylene glycol, 1,3- or 1,4-butanediol and nucleic acid diol, Or a polyester polyol is used as the polyurethane resin component.
As the acrylic resin, polymethylmethacrylate alone or an acrylic resin copolymerized with a polymethylmethacrylate and a component having a longer aliphatic group in the branched molecule is used. Cellulosic resin is used as the cellulose resin, As the vinyl resin, a resin in which vinyl acetate and a copolymer of vinyl alcohol and vinyl acetate are copolymerized is used as a component mainly composed of vinyl chloride. Examples of the epoxy resin include bisphenol A type, bisphenol F type, brominated bisphenol A type, bisphenol S type , Glycidyl ether type epoxy resins such as bisphenol AF type, bisphenyl type, naphthalene type, phenol novolak type, cresol novolak type, DPP novolak type, trishydroxyphenyl methane type and tetraphenyl ethane type, hexahydrophthalic acid ester Glycidyl ester type epoxy resin such as phthalic acid ester type, A glycidyl amine type epoxy resins such as sidil diaminodiphenyl methane, aminophenol type, aniline type, toluidine type, is used.
In addition, the adhesion reinforcing agent in the solid content serves to enhance the adhesion between the coating film and the substrate, and one or more of hydrocarbon, ketone, acetate and chlorinated polypropylene is selectively used. Examples of the stabilizer include an antioxidant, Absorbents and the like are used.
Further, at least one of a dispersant, an inorganic particle, an antioxidant, an ultraviolet stabilizer and an absorbent may be used singly or as a mixture in an additive in a solid content.
Of these additives, additives for improving dispersibility are polyester-polyamine copolymers and the like for improving the mixing property of the resin and non-resin in the coating solution, and the additives for improving the slip property are the smoothness Polyethylene wax, inorganic particles and the like are used for the purpose of preventing surface defects such as scratches.
In addition, phthalocyanine-based organic pigments are used as the colored organic pigments in the solid content, and more preferably blue colored organic pigments among the colored organic pigments of the phthalocyanine type are used to disperse the blue pigment in the coating layer as a whole The surface emissivity of the aluminum surface material is maintained and the stability of the color is maintained while preventing the reflection of light inherent to the aluminum surface material and the presence or absence of the aluminum surface material can be visually distinguished easily.
Solvents constituting the colored coating solution mixed with the solid components may be used alone or in combination of aromatic hydrocarbon, acetate and chlorine solvents. Examples of the aromatic hydrocarbon solvents include toluene, benzene, and xylene. As the acetate solvent, at least one selected from the group consisting of ethyl acetate and butyl acetate is used, and as the chlorine solvent, at least one selected from the group consisting of methylene chloride and chloroform is used.
On the other hand, when coating a colored coating solution on an aluminum surface material, a coating roller is usually used. It is preferable to use a coating roller having a carpenter of about 150 to 600 dpi considering the mixing ratio of solid and solvent .
If the carpenter of the coating roller is less than 150 dpi, the amount of coating excessively increases to increase the thickness of the final coating layer, thereby unnecessarily raising the surface emissivity of the aluminum surface material. If the carpentery of the coating roller is 600 dpi or more, This is easy, however, since the viscosity of the coating solution used does not match the uniformity of the coating layer.
The thickness of the coating layer formed on the surface of the aluminum surface material is preferably 1 μm or less. To this end, it is necessary to adjust the coating amount of the organic material on the aluminum surface material to 0.1 to 0.7 g / m 2 , If the amount is less than 0.1 g / m 2, the thickness of the coating layer becomes excessively low, which makes it difficult to guarantee the stability of the aluminum layer for a long time. When the organic coating amount exceeds 0.7 g / m 2 , the thickness of the coating layer becomes thick, .
The pigment that can be used in the present invention can be broadly divided into inorganic pigments and organic pigments. The inorganic pigments have poor color tone and poor coloring power compared to organic pigments, but have high heat resistance and solvent resistance. However, since organic pigments are very useful for reducing the thickness of coating layer, organic pigments are more suitable than aluminum pigments for surface coating of aluminum.
Examples of the organic pigments having such properties include yellow to red azo based organic pigments, blue based phthalocyanine based organic pigments, and organic pigments having a condensed polycyclic aromatic cyclic ring structure. Among these organic pigments, a coating layer using phthalocyanine based organic pigments Has a very stable characteristic against discoloration when it is exposed to the outside air or sunlight, and thus has characteristics very suitable for the present invention.
Accordingly, the aluminum surface material for thermal insulation obtained through the present invention satisfies the basic function of preventing the corrosion and oxidation even if the coating layer formed on the surface of the aluminum surface material is exposed to oxygen or moisture in the air, Since the colored organic pigments contained in the coating solution can easily be visually confirmed by the naked eye during the coating operation for obtaining such a coating layer, the coating can be entirely coated without the uncoated region by only one coating, Pigment can prevent visible light reflection inherent to aluminum surface material. Especially, it is possible to visually identify the presence or absence of aluminum surface material due to blue organic pigments distributed throughout the coating layer. Therefore, It is possible to increase the reliability of the consumers.
