を提供するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to decorative laminates! ! ! This relates to a decorative sheet used as a decorative surface material during construction, and it not only can be extremely easily adhered to the base material for decorative laminates, but also can be bonded to the decorative sheet adhered to the base material for decorative laminates. The present invention provides a decorative sheet having a function of maintaining strong adhesive strength with the base material for a decorative board without deteriorating even in a high temperature atmosphere.

ーコート紙タイプのものとが存する。Used as a surface decorative material for furniture, walls, etc.! The sheet is a pre-coated paper type that has a surface protective layer that is made by applying a top coat of thermosetting resin such as urethane resin, amino alkyd resin, or two-component curing resin to the surface of the base sheet and then curing it. A base material sheet without a surface protective layer was attached to plywood, particle boat 5, etc. as a base material for a decorative board, and an amino alkyd resin, melamine resin, etc. was applied to the surface as a surface protective layer and cured. There is also an after-coated paper type.

。However, in order to attach each decorative sheet and the base material for decorative laminate described above, an adhesive is applied to the surface of the base material for decorative laminate immediately before the adhesion process, and then this is laminated using a heat-pressing method. There are two types: one in which a thermoplastic synthetic resin layer is pre-coated on the back side of the decorative sheet, and the thermoplastic synthetic resin layer is used to apply heat and pressure to the decorative board base material. .

を有している。By the way, in the case of pasting between the decorative sheet and the base material for decorative board, it is absolutely necessary to have an adhesive applicator in the production line if an adhesive application process is performed immediately before the former pasting process. However, there are disadvantages such as environmental problems such as adhesive odor and adhesive contamination associated with the application process, and an unavoidable increase in indirect departmental costs such as personnel costs and utility costs. have.

部の耐熱性が乏しいという欠点を有している。In addition, in the case of a decorative sheet in which a thermoplastic synthetic resin layer is pre-formed on the back side of the latter, when the bonded body of the decorative board base material and the decorative sheet is placed under heating conditions, the thermoplastic resin layer as an adhesive layer is formed. The synthetic resin layer is reactivated, and peeling may occur between the base material for the decorative board and the decorative sheet, and the bonded portion generally has the disadvantage of poor heat resistance.

シートを提供し得たものである。In contrast, the decorative sheet of the present invention is of a type in which an adhesive layer is previously formed on the back surface, and the adhesive layer is also composed of an uncured or semi-cured thermosetting resin. As it is a decorative sheet with a thermoplastic synthetic resin layer pre-formed on the back side, the process of attaching it to the base material for decorative laminate is easy, and the process of attaching it to the base material for decorative laminate and the decorative sheet is easy. It is possible to provide a decorative sheet that can form an adhesive part with excellent heat resistance between the decorative sheet and the sheet.

Unsaturated polyester resin, thermosetting acrylic resin, melamine resin, etc. are used singly or in mixtures of two or more, but in particular, adhesive layers made of melamine resin and mixed resins of melamine resin and acrylic resin are used. The adhesive layer is
It exhibits superior adhesion ability through heat and pressure. However, as the melamine resin, methylolmelamine resin is suitable, and as the acrylic resin, water-soluble acrylic resin is suitable. In addition, in the case of an adhesive layer made of a mixed resin of melamine resin and acrylic resin, the weight ratio of both is set to melamine resin/acrylic resin = 5/1 to 115.
It is preferable to mix the adhesive within the range of melamine resin/acrylic resin = 2/1 to 1/2. When forming a layer using the roll lamination method, a large amount of low melting point acrylic resin is used to improve initial adhesion, and when forming an adhesive layer using the press lamination method, a large amount of melamine resin is used. It is preferable to increase the amount of the adhesive to improve the adhesion strength of the adhesive.
