【考案の詳細な説明】
本考案は浮力が強く、しかも強靭なフロートに関するも
のである。[Detailed Description of the Invention] The present invention relates to a float that has strong buoyancy and is strong.
近時、合成樹脂発泡体、特にポリスチレン発泡体からな
るフロートが広く使用されるようになった。In recent years, floats made of synthetic resin foams, particularly polystyrene foams, have come into wide use.
しかし、合成樹脂発泡体は、一般に脆弱であって破損し
易く、耐久性に欠ける欠点がある。However, synthetic resin foams are generally brittle, easily damaged, and lack durability.
本考案者は合成樹脂発泡体の有する長所を活かし、しか

ある。The inventor of this invention has developed this invention as a result of research to make use of the advantages of synthetic resin foam and to create a strong float.This invention is based on the outer layer of polystyrene foam that has been expanded to a high magnification. The gist of the float is that a polyester resin layer is formed on the outer surface of a core material covered with a resin foam.
本考案のフロートの芯材を構成するポリスチレン発泡体
は高倍率に発泡した発泡体が用いられ、例えば３０〜６
０倍、好ましくは４０〜６０倍発泡のものが用いられる
。The polystyrene foam that constitutes the core material of the float of the present invention is a foam that has been expanded to a high ratio, for example, 30 to 6
The one that is foamed 0 times, preferably 40 to 60 times, is used.
このポリスチレン発泡体の外層にはポリオレフィン系樹
脂発泡体が被覆されている。The outer layer of this polystyrene foam is coated with a polyolefin resin foam.

覆せられている。As this polyolefin resin, polyethylene, polypropylene or a copolymer resin thereof is used,
The polyolefin resin foam is coated on the polystyrene foam to a thickness of 30 mm or more, preferably 50 to 100 mm thick.

ル成形用樹脂、殊にガラス繊維を混和したポリエステル
樹脂またはガラス繊維布状物を捲回した上にポリエステ
ル成形用樹脂を塗装して硬化せしめてポリエステル樹脂
層とされている。A polyester resin layer is formed as the outermost layer, and a polyester molding resin, especially a polyester resin mixed with glass fiber, or a glass fiber cloth is wound, and then the polyester molding resin is coated and cured to form a polyester resin. It is said to be a layer.
図面によって説明すれば、（１）は高倍率に発泡したポ
リスチレン発泡体であり、（２）はポリエチレン発泡体
でポリスチレン発泡体（１）の全表面に密着して被覆せ
られている。To explain with reference to the drawings, (1) is a polystyrene foam that has been expanded to a high magnification, and (2) is a polyethylene foam that is tightly coated on the entire surface of the polystyrene foam (1).
３はガラス繊維を混和したポリエステル樹脂層であり、
前記ポリエチレン発泡体２の全表面にポリエステル成形
用樹脂を塗装被覆し、硬化して得られたものである。3 is a polyester resin layer mixed with glass fiber,
It is obtained by coating the entire surface of the polyethylene foam 2 with a polyester molding resin and curing it.
本考案のフロートは、上記の如く高倍率に発泡したポリ
スチレン発泡体１が芯材とされているので極めて軽量で
浮力が強い。The float of the present invention is extremely lightweight and has strong buoyancy because the polystyrene foam 1 that has been expanded to a high magnification as described above is used as the core material.
また、ポリスチレン発泡体１の外層にはポリエチレン発
泡体２の如きポリオレフィン系樹脂発泡体が被覆せられ
ているので安定であり、従って内蔵されるポリスチレン
発泡体１は高発泡でそれ自体脆弱であっても全く支障は
ない。In addition, the outer layer of the polystyrene foam 1 is covered with a polyolefin resin foam such as the polyethylene foam 2, so it is stable, and therefore the polystyrene foam 1 contained therein is highly foamed and is itself fragile. There is no problem at all.
また、再生したポリスチレン発泡体も使用することがで
きる。Recycled polystyrene foam can also be used.

ン、トルエン、キシレン等の溶剤によってポリオレフィ
ン系樹脂発泡体は侵されないので、芯材の形状が変化す
ることなくポリエステル樹脂層を形成せしめることがで
きる。Since the polyolefin resin foam is not attacked by solvents such as malelstyrene, benzene, toluene, and xylene in the polyester molding resin, the polyester resin layer can be formed without changing the shape of the core material.
ポリエステル樹脂層３、特にガラス繊維を混和したポリ
エステル樹脂層３は極めて強靭であり、余り厚い層は必
要でなく、一般に数關ないし１０数朋で充分である。The polyester resin layer 3, especially the polyester resin layer 3 mixed with glass fiber, is extremely strong and does not require a very thick layer, and generally a few to ten thick layers are sufficient.

材が用いられているので極めて軽量で浮力が強く、外層
がポリエステル樹脂層３で形成せられているので耐衝撃
性、耐久性が良好である。The float of the present invention uses a core material made of highly expanded polystyrene foam 1 covered with polyolefin resin foam, so it is extremely lightweight and has strong buoyancy, and the outer layer is made of polyester resin layer 3. It has good impact resistance and durability.
従って、ポリエステル樹脂層３は亀裂を生じたり、破損
したりするかそれは極めて少いが、かりに亀裂を生じて

レン発泡体が充満されているので浮力が低下することが
ない。Therefore, the polyester resin layer 3 is very unlikely to crack or break, but even if it does crack, it will not be buoyant because the inside is filled with polyolefin resin foam and polystyrene foam. It never declines.
また亀裂が生じても、ポリエステル成形用樹脂を塗装し
て修複することができるので、極めて経済的である。Furthermore, even if cracks occur, they can be repaired by painting with polyester molding resin, which is extremely economical.
