Problems solved by technology

[0004] When the adhesive sheet having the above-mentioned hot-melt resin powder on the surface is press-molded on other members, the press-molding temperature is the curing temperature of the thermosetting resin contained in the adhesive sheet or above, In this way, the hot-melt resin cannot ensure the initial adhesive strength of the adhesive sheet and other members due to excessive melting, so there is a problem of mutual peeling.

Embodiment 1

[0070] according to figure 1 The production method of the adhesive sheet 1 shown above manufactures the adhesive sheet 1 of this invention. Hereinafter, the manufacturing method of the adhesive sheet 1 of this Example is demonstrated in detail.

[0071] Take out the porous sheet 2 (non-woven fabric made of polyester fiber, weight per unit area 50g / m2) from the roller 10 2 ), and introduce the porous sheet 2 into the synthetic resin impregnation tank 14 filled with the synthetic resin 4 liquid through the guide rollers 11, 12, 13. In addition, the synthetic resin 4 filled in the synthetic resin immersion tank 14 is 50 mass % aqueous solution of the initial stage cocondensation product of phenol, alkyl resorcinol, and formaldehyde.

[0072] The porous sheet 2 is impregnated with a synthetic resin 4 in a synthetic resin impregnation tank 14 , and is then squeezed by a squeeze roller 15 to adjust the impregnated amount of the synthetic resin 4 . Here, with respect to the porous...

Embodiment 2

[0076] The blank 1A of the adhesive sheet 1 obtained in Example 1 was stored at room temperature (25° C.) for one month, and the adhesive sheet 1 obtained from the stored blank 1A and Example 1 were used. The laminated material 5 is manufactured by compression molding on the core material 6 by the same method. Even when the adhesive sheet 1 stored for one month was used, the laminated material 5 with sufficient adhesive strength was obtained.

[0077] Furthermore, the adhesive sheet 1 obtained from the blank 1A stored at room temperature (25° C.) for 6 months was used, and press-molded on the core material 6 in the same manner as in Example 1 to produce a laminated material 5 . Even in the case of using the adhesive sheet 1 stored for 6 months, the laminated material 5 with sufficient adhesive strength was obtained.

[0078] Therefore, the adhesive sheet 1 of the present invention is excellent in adhesiveness. Furthermore, if the adhesive sheet 1 of this invention is used, t...

Abstract

A stacking material used as the interior material of a car and an adhesive sheet used for the stacking material, the adhesive sheet wherein a porous sheet is soaked with synthetic resin and thermosetting resin powder is placed on the surface of the porous sheet, the stacking material wherein the adhesive sheet is stacked at least on a core material and the other members such as skin material.

Description

technical field [0001] The present invention relates to an adhesive sheet used, for example, as an automobile interior material or building material, and a laminated material obtained by laminating the adhesive sheet and other members. Background technique [0002] Conventionally, as such an adhesive sheet, a porous sheet such as a fiber sheet is impregnated with a thermosetting resin such as a phenolic resin and cured into a B state. The adhesive sheet is superimposed on other members, and bonded and laminated on other members by thermocompression bonding, and if necessary, molded into a predetermined shape at the same time. However, if the above-mentioned adhesive sheet is stored for a long period of time, the curing of the impregnated thermosetting resin will exceed the B state, so that the adhesiveness of the adhesive sheet and other members will be lost. Therefore, there is provided an adhesive sheet in which hot-melt resin powder such as ethylene-vinyl acetate copolym...
