Problems solved by technology

In this way, in the case of using a cylindrical parison with a substantially uniform wall thickness in the circumferential direction, there will inevitably be a difference in thickness between the wall surface having a plurality of recesses and the wall surface not formed with recesses after blow molding, so that the resin cannot be realized. Sufficient weight reduction and thinning of laminated boards

Embodiment Construction

[0015] Hereinafter, an embodiment of the method for manufacturing the resin laminate 100 according to the present invention will be described in detail with reference to the drawings. Such as Figure 1 to Figure 3 As shown, the resin laminate 100 includes: a surface side sheet 120A, a back side sheet 120B, a decorative material sheet 140 attached to the outer surface 150 of the surface side sheet 120A, and the resin laminate 100 is a decorative material sheet 140, a surface side sheet 120A and the laminated structure of three layers of the back side sheet 120B. It should be noted that, in figure 1 In FIG. 2 , in order to clearly show the internal structure of the resin laminated board 100 , the periphery of the resin laminated board 100 is omitted for illustration.

[0016] The respective thickness (wall thickness) of the front side sheet 120A and the back side sheet 120B and the overall thickness (board thickness) of the vehicle interior fitting 100 may be appropriately det...

Abstract

Provided is a method for manufacturing a resin laminate. Said method includes: a step in which a two-piece mold is provided, wherein the cavity of one piece of the mold is provided with a plurality of protrusions that protrude towards the other piece of the mold, and two thermoplastic resin sheets in a molten state are prepared with regulated thicknesses; a step in which the two molten thermoplastic resin sheets are positioned at a prescribed separation from each other between the two pieces of the two-piece mold so as to protrude outside a ring-shaped pinch-off; a step in which a sealed space is formed between one sheet and the cavity of one mold piece facing the outer surface of that sheet; a step in which suction is applied to the aforementioned sealed space from the mold piece side and the outer surface of that sheet is pushed up against the cavity of that mold, thereby diluting that sheet and forming a depression; and a step in which the mold is clamped shut, thereby bonding the outer edges of the two molten thermoplastic resin sheets to each other and also bonding the tip of the depression formed in one sheet to the inner surface of the other sheet.

Description

technical field [0001] The present invention relates to a method for producing a resin laminate, and more specifically, to a method for producing a resin laminate capable of achieving sufficient weight reduction and thickness reduction while ensuring production efficiency and product quality. Background technique [0002] Conventionally, so-called resin laminates have been used as automotive interior parts, building materials, distribution and packaging materials. The resin laminated board has a resin-made surface material and a resin-made back surface material, and the back surface material is provided with a concave part whose front end part abuts the inner surface of the surface material. In particular, a nonwoven fabric is pasted on the front side of a surface material for automotive interior parts or building materials that emphasize appearance. Conventionally, various methods have been adopted as a method for producing the resin laminated board. First, a technique of...
