Abstract

PURPOSE:To make it possible to weld a base material with a skin material easily without causing failure or deterioration or the like of a surface layer of a base resin sheet, by melting the surface layer by hot air of a specified temperature. CONSTITUTION:After a surface layer part of the laminate surface of a base material of a thermoplastic resin sheet is melted by hot air of a temperature of a melting point of the base material +100 to 300 deg.C, a skin material is laminated thereon, and a laminate thus prepared is contact-bonded between pressure rolls in a pair and then cooled down. A base sheet 1 is fed to the pressure rolls 3 by a guide roll 5. The hot air heated to a prescribed temperature is applied onto the surface of the base material from a hot-air blowing port 4 provided movably in the longitudinal and vertical directions above the base material in front of the rolls 3, the surface is melted and joined together with the skin layer 2 fed from the other side, laminated by subsequent pressure rolls and cooled, and then the laminate thus prepared is taken out as a composite sheet, a product. The thermoplastic resin sheet of the base material to be used is preferably an olefin foamed resin sheet, in particular, and the multiplication rate of foaming thereof is seven times or below, or five times preferably. As for the skin material to be used, a fabric leaf, woven fabric, nonwoven fabric and a highly-foamed resin sheet can be enumerated.

ものでも使用される。FIG. 1 shows an apparatus for manufacturing a composite sheet by adding M layers of skin material to a thermoplastic resin sheet or a foamed sheet according to the present invention.
The resin sheet 1 can be used either in-line or out-of-line as it is from sheet or foam sheet manufacturing equipment.

る。The sheet 1 is conveyed toward the pressure roll 3 by a guide roll 5. Hot air heated to a predetermined temperature is radiated onto the surface of the base material from a hot air outlet 4 provided on the top surface of the base material in front of the roll 3 so as to be movable back and forth and up and down, and the surface is melted and sent to the other side. The product is layered with a skin material, then subjected to mmM using a pair of press rolls, cooled, and then taken out as a product composite sheet.

調をもたらす。The base thermoplastic resin sheet used in the present invention includes:
In particular, as the expansion ratio increases by 1, which is preferable for olefin foam resin sheets, it becomes difficult to adjust the molten state when melting the surface of the base material. As a result, the laminated state becomes unsatisfactory.

しながて１発泡倍率は７倍以下、好ましくは５倍である
１発泡倍率２以下を低発泡、２〜８倍を中発泡、８倍以
上を高発泡と言う。Therefore, the foaming ratio is 7 times or less, preferably 5 times, and a foaming ratio of 2 or less is called low foaming, 2 to 8 times is called medium foaming, and 8 times or more is called high foaming.
