燃性であるがため、火災の発生時には延焼し易いととも
に有害ガス等の発生が多いという欠点もある。(Prior Art) In recent years, with the diversification of buildings, the performance of building materials has improved, and as a result, many plastic building materials have come to be used as interior or exterior materials. Compared to cement-based building materials, these plastic building materials are lightweight, have excellent heat insulation properties, environmental resistance against humidity and freezing, decorative properties, and productivity/processability, but on the other hand, they are flammable. Because of this nature, when a fire breaks out, it tends to spread easily and generates a lot of harmful gases.

煙性樹脂であるフェノール系樹脂を使用する等の種々の
対策が試みられている。In order to improve these drawbacks, the amount of plastic used should be kept to the minimum necessary for molding building materials, and flame retardants such as aluminum hydroxide should be added, and phenolic resins, which are low smoke-emitting resins, should be used for plastics. Various countermeasures such as these have been attempted.

徴とするものである。(Means for Solving the Problems) The method for producing a phenolic resin composite molded body of the present invention includes coating steel slag particles with a novolac type phenol resin in a weight ratio of 20 to 100 g per 1 liter of steel slag, It is characterized by putting this into a mold and heating and curing it.
本発明でいう鉄鋼スラグとは、鉄鋼を生産するときに発
生するもので、一般にＣａＯとＳｉＯ２の２成分を主成
分としており、銑鉄を生産するときに生成する高炉スラ
グと粗鉄を生産するときに生成する製鋼スラグを指す。The steel slag referred to in the present invention is generated when producing steel, and generally has two main components, CaO and SiO2, and is produced when producing blast furnace slag and crude iron when producing pig iron. Refers to the steelmaking slag produced in

含有している。また、鉄鋼スラグは有害物質を含まず、
しかも耐熱耐火製、断熱性に優れるため、例えば高炉ス
ラグの場合は、セメント原料等に用いられている。Steel slag contains Afz(h) and MgO in addition to the above two components, and steelmaking slag contains Fe01Mg0, MnO, etc.In addition, steel slag does not contain harmful substances,
Moreover, it is made of heat-resistant, fire-resistant material and has excellent heat insulation properties, so in the case of blast furnace slag, for example, it is used as a raw material for cement.

であってもよい。The average particle size of the steel slag particles used in the present invention (50% particle size in particle size distribution measured by standard sieve measurement) is 0.15
~2.5 mm. If the average particle diameter is less than 0.15 mm, the specific surface area increases, so a large amount of resin is required to bind (bind) the steel slag particles with resin, and as a result, nonflammability cannot be ensured. Moreover, if the average particle size exceeds 2.5 mm, the airtightness and surface smoothness of the molded product will be extremely poor. In particular, steel slag with a narrow particle size distribution and an average particle size of about 0.3 to 1.2 mm is preferably used. These iron slags may be treated with a coupling agent such as aminosilane or acrylic silane for the purpose of improving interfacial adhesion with the phenolic resin.

なるとともに、耐燃焼性に優れた建築材料となり得る。(Function) According to the method for producing a phenolic resin composite molded article of the present invention, a large amount of inorganic steel slag particles are replaced with a very small amount of organic novolac type phenol, which is a flame-retardant resin that emits very little smoke when burned. Since the slag aggregate is coated with a resin and bonded by heating and curing in the mold, the slag aggregates are evenly bonded to each other by organic matter without applying pressure in the mold during heat curing, and the physical structure is controlled. This makes it possible to maximize the strength of the molded product, and it can also be used as a building material with excellent flame resistance.
