Zusammenfassung: | The invention discloses a construction method of an ultraviolet-resistant package outer maintenance layer. The method comprises the following steps that a first adhesive layer is constructed on the outer surface of a package so as to adhere the first adhesive layer to the outer surface of the package; a flame-retardant layer is constructed on the outer surface of the first adhesive layer so as toreduce the damage of flame to an internal structure of the outer surface of the package; a second adhesive layer is constructed on the outer surface of the flame-retardant layer so as to bond the flame-retardant layer and an ultraviolet-resistant layer; and the ultraviolet-resistant layer is constructed on the outer surface of the second adhesive layer so as to reduce the damage of ultraviolet rays to the internal structure of the outer surface of the package. According to the construction method of the ultraviolet-resistant package outer maintenance layer, the ultraviolet-resistant package outer maintenance layer wit |
