The technique of mixing a liquid binder such as melamine resin and urea resin, and solidifying the mixture by heating and pressurizing to produce an artificial building material, etc., is a known technique that has already been partially put to practical use. Naturally, these building materials, which are formed by solidifying the fusible fibers with a flammable binder, become flammable building materials, which can cause fire, which is the largest waste of resources, and the degree of fire caused by the generated gas. Furthermore, given the increasing number of tragedies that result in the death torment, measures to combat these inflammations can play an important role both economically and socially.

本発明の組成物の経済性が更に増大する。As the binder (c), a synthetic resin binder such as a phenol resin, a melamine resin, and a urea resin is used. When using synthetic resin waste materials (B) such as polyvinyl chloride, polyethylene, and polystyrene together with the main raw material (A), the waste materials are melted by heating to serve as a binder. The use amount of c) can be reduced. This makes it possible to reuse hard-to-dispose plastic waste materials,
The economics of the composition according to the invention are further increased.

Imparts properties. That is, 10 to 20 parts by weight of the flameproofing agent composition (D) was kneaded with 100 parts by weight of the composition obtained by mixing the materials (A), (B) and (C) in the above mixing ratio, and then heated. It is pressed to obtain the flame-retardant composition of the present invention.

た人造木材は、現在、日本の廃棄物対策としては、重要
であるばかりでなく、防火対策、森林資源擁護対策にと
っても、見逃す事の出来ない発明である。[0008] In the waste, there is much paper in terms of quantity. The spread of recycled paper is also important as a method for treating discarded paper, but it is not technically possible to recycle all paper waste. Therefore, the incombustible composition of the present invention, which can be used for any waste paper or any waste wood as a raw material, and artificial wood using the same, are not only important at present as waste measures in Japan, but also fire prevention measures, This is an indispensable invention for forest resource protection measures.

果を発揮出来ることは特記すべき事である。[0009] Waste materials such as vinyl of the composition (B) are ones that are currently difficult to treat. It should be noted that these materials can be used as raw materials for artificial wood and reduce the amount of expensive binders used.

材（Ｂ）を針状のかんなで削って、綿状に粉砕して原料
とするのである。それ故、落綿などは直ちに原料となり
得るのである。綿状に出来ない材料は、微粉砕する。Most preferably, the waste paper (A) and the waste vinyl material (B) are ground with a needle-shaped planer and crushed into a cotton-like raw material. Therefore, cotton drop can be used as a raw material immediately. Materials that cannot be made into cotton are finely pulverized.
【００１１】植物質の繊維質のみでなく、例えば、ナイ
ロン屑等人絹類のくずを綿状にして組成物Ａに混合使用

前者に比較して弱い。[0012] Artificial wood containing a large amount of cotton-like material generally has a beautiful surface when it is made into a product, and also has a characteristic that its bending strength is stronger than its compressive strength. A product containing a large amount of finely pulverized aggregate has a slightly rough skin, and its bending strength is weaker than that of the former.

Consisting of (c) alone or in combination selected from magnesium chloride and calcium chloride, (a): (b):
The composition of (c) has a weight ratio of 1: 0.5 to 1.5: 0.5 to 1.5 (preferably 1: 1: 1).

言う事が出来る。If the [flameproofing agent composition D] is added to the mixture of the above-mentioned "compositions (A), (B) and (C)" and agitated and heated to give a product, the product does not contain a flameproofing agent. Compared to the one
Significantly increases flame retardancy. This can be said to be the greatest feature of the present invention.

め、続けて燃焼する為には、多量の熱量を必要とするこ
ととなり、結果的に、熱量不足を生じ、自己消火する事
になるものと考えられる。In general, the flame-retardant / flame-retardant action requires a large amount of heat in order to continue burning because the flame retardant reacts with heat to generate an endothermic action by the addition of the flame retardant. As a result, it is considered that there is a shortage of heat and self-extinguishing occurs.
【００１７】又、可燃性物質の熱による脱水作用を、例

のと考えられている。In addition, the dehydration effect of the combustible substance due to heat is released, for example, by the release of water of crystallization contained in the inorganic flame retardant.
It is considered that actions such as prevention and inactivation are taken into consideration.
【００１８】上記防炎剤（Ｄ）はこれらの作用を兼ね備

記載がある。The flame retardant (D) can be considered to have both of these effects. Standard A1321-1975 entitled "Method of Testing Flame Retardancy of Interior Materials of Buildings"
Stipulates a method for testing the flame retardancy of a material used for the interior of a building in the early stage of a fire, and has the following description.

この規格の用途、物性等を抜粋すると次の通りである。The standard A5908-1986 concerning "Particle Board" is based on the principle that a small piece of wood is used as a main raw material and a density of 0.5 g / cm 3 is formed by hot pressing with an adhesive.
It is specified for a plate having a thickness of 0.9 g / cm 3 or less.
The usage and physical properties of this standard are as follows.

達成されるものである。As described above, the standard of "particle board" defines only the flame-retardant second-grade product and the flame-retardant third-grade product. Flame retardant grade 1 products are achieved for the first time by the use of the flame retardants of the present invention.

It is possible to manufacture boards floating in water, and conversely, if high-density aggregate is mixed in, it is possible to freely manufacture solid heavy boards such as rocks.

ップ等を増加させることが必要となる。In order to produce light artificial wood having a density of 0.9 without using lightweight aggregates, it is necessary to use a large amount of waste paper made of waste paper as the material (A), as much as possible. It is difficult to achieve, and it is necessary to increase the number of wood chips and the like as in a particle board.

ルボードに十分匹敵するものである。The composition for a flame-retardant board of the present invention uses a large amount of waste paper such as waste paper and wood chips, and in some cases, effectively uses synthetic resin waste material, and uses a specific flameproof material. By adding the agent composition, it is possible to achieve the first grade of flame retardancy, and the strength is sufficiently comparable to that of a conventional particle board.
