下地材に関する物である。DETAILED DESCRIPTION OF THE INVENTION The present invention uses a plate-shaped material made of foamed plastic as a substrate, and coats one or both surfaces of the substrate with a first coating composition consisting of an aqueous liquid containing an aqueous emulsion as a main component and an isocyanate compound or an isocyanate polymer. It is characterized by coating the product (a), and then painting or spraying a second coating composition (b) containing as main components one or more of an aqueous emulsion and a powdery material, a granular material, and a fibrous material. Lightweight and fire resistant,
This article relates to a base material for mortar coating that has excellent soundproofing properties, heat insulation properties, and workability.
従来よりポリスチレン発泡体、硬質ポリウレタ
ン発泡体等を素材とする材料が断熱材として建築
の際壁面の内側に使用されている。 BACKGROUND ART Conventionally, materials made of polystyrene foam, rigid polyurethane foam, etc. have been used as heat insulating materials on the inside of walls in construction.
これらは軽量で断熱性に優れている一方表面が

果も小さくコスト的にも高価である。 Although these are lightweight and have excellent insulation properties, they have a rough surface and low strength and cannot be used as wall or ceiling materials as they are, so they are pasted on one or both sides of the foam using plywood or gypsum board adhesive. However, in both cases, a base paper of wood or gypsum board is placed on the surface, which not only does not improve the fire resistance, but also has a small soundproofing effect and is expensive.

を保証するために使用されている。 In this construction method, the innermost framework is intended to support the rough wood board, and the rough wood board serves as a support base for the waterproof paper sheet and lath netting.When the waterproof paper sheet is coated with cement mortar, water escapes to the back side, resulting in water shortage. It is used for the purpose of preventing poor curing, and also lath netting,
It is used to ensure the retention of the cement mortar layer on the wall by enclosing the lath network when the cement mortar hardens.

難いことなどが欠点として指摘されている。 In this way, in the case of cement mortar coating, the preparation process requires a lot of labor, which is an impediment to rationalization, but in recent years, in order to solve these problems, toluene, xylene, ethyl acetate, etc. It is an integral panel coated with a resin or rubber paint soluble in organic solvents such as butanol, or a mixture of cement and synthetic resin, and can replace the conventional rough wood boards, waterproof paper sheets, and lath mesh. Efforts are being made to streamline the process, but there are problems such as the use of large amounts of organic solvents in the manufacturing process, poor workability when cutting cement-coated panels, and difficulty in achieving the adhesion of cement mortar on-site. It has been pointed out as a drawback.
本発明はこれら両者の欠点を排除したモルタル
塗装用軽量下地板を提供するものである。 The present invention provides a lightweight base plate for mortar coating that eliminates both of these drawbacks.
