Abstract
The present invention relates to functional type prime paint. In the present invention, a copolymer of ethylene glycol, terephthalic acid, sebacic acid, etc. is used as main resin for bonding and is added with mixed resin of nitrocellulose and acrylic resin and a copolymer of ethylene glycol, terephthalic acid, sebacic acid and isoprene alcohol to prepare a solvent type glue solution with a mixed solvent of butanone, ethyl acetate, isopropyl alcohol, etc.; the solvent type glue solution is applied to an aluminum foil by a gravure coating method to form a coating layer which is coated with hot-melt adhesive. The prime paint is a coating agent with certain functions, which is used for metal, such as aluminum foils, etc. A film formed after the paint is applied has the advantages of properties of thermosetting resin of high density, insolubility, etc. and higher surface tension of thermoplastic resin, and the high-efficiency secondary coating can be performed on the film. When applied to the aluminum foil as a blister package, the prime paint can effectively protect medicines without activity spoiling even though the aluminum foil package with the prime paint contains volatile substances, as well as can ensure that a hot-melt adhesive layer does not swell to desquamate during medicine storage and during a specified time.
