SYNTHETIC RESIN TATAMI MAT MANUFACTURING METHOD AND SYNTHETIC RESIN TATAMI MAT
PROBLEM TO BE SOLVED: To provide a synthetic resin tatami mat in which a mold structure is relatively simple, a manufacturing process can be shortened, and the contraction anisotropy in the molding is extremely reduced.SOLUTION: A manufacturing method of a synthetic resin tatami mat is characterized as follows: a thermosetting paint is applied on a cavity bottom surface formed of grooves for forming tatami mat patterns and 4-cavity sides in a state of mold opening by using a mold device for polyurethane molding; a synthetic fabric clothing material having a rectangular shape in which a ratio (P/R) of the length (P) in the tatami mesh direction to the length (R) in the vertical direction of the tatami mesh is 1.10-1.30 and having an area of 0.65-0.87 times of an area of a cavity bottom surface is placed on an application surface of the paint; a thermosetting foaming polyurethane raw material is injected in a cavity; a thermosetting polyurethane is foamed and cured after clamping and the paint is also cured; a coating film, the synthetic fabric clothing material and polyurethane foam are molded integrally by performing the mold opening thereafter; and irregular tatami mat patterns are formed on a tatami mat.SELECTED DRAWING: Figure 1
【課題】金型構造が比較的簡単で、製造工程の短縮を図ることのでき、かつ成形の際に収縮異方性の極めて少ない合成樹脂製畳を提供することを目的とする。【解決手段】ポリウレタン成形用の金型装置を使用して、型開きの状態で、畳模様を形成するための溝が形成されたキャビティ底面と４つのキャビティ側面に熱硬化性塗料を塗布し、該塗料の塗布面上に、畳目方向の長さ（Ｐ）と畳目に垂直方向の長さ（Ｒ）との比（Ｐ／Ｒ）が１．１０〜１．３０の長方形状で、面積がキャビティ底面の面積の０．６５〜０．８７倍の合成繊維製布を載置し、キャビティ内に熱硬化性の発泡ポリウレタン原料を注入し、型締後に熱硬化性のポリウレタンを発泡硬化させると共に前記塗料も硬化させ、その後型開きすることにより、塗膜、合成繊維製布、及びポリウレタンフォームを一体成形して、畳表に凹凸のある畳模様を形成する、合成樹脂製畳の製造方法。【選択図】図１
