ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hard polyvinyl chloride resin composition having excellent fire retardant properties. The present invention relates to a hard polyvinyl chloride resin composition having excellent fire retardant properties.
硬質塩化ビニル樹脂は耐水性、耐薬品性、電気絶縁性及

プ、タンク、ダクト等の工業材料、電気機器用材料、雑
貨、その他に広く用いられている。Hard vinyl chloride resin has excellent water resistance, chemical resistance, electrical insulation, and mechanical properties, so it is used as building materials, industrial materials such as boards, pipes, tanks, ducts, materials for electrical equipment, miscellaneous goods, etc. Widely used.
硬質塩化ビニル樹脂は難燃性であって、他のプラスチッ
クに比較して燃焼し難い樹脂に属しているが、無機材料
や金属材料のように不燃性ではないため、その用途があ
る程度制限される場合がある。Hard vinyl chloride resin is flame retardant and belongs to the class of resins that are less combustible than other plastics, but because it is not nonflammable like inorganic and metal materials, its uses are limited to some extent. There are cases.
塩化ビニル樹脂を難燃化させるために、従来から三酸化
アンチモン、三酸化モリブデン、ホウ酸亜鉛、ホウ酸バ
リウム、トリクレジルホスフェート等のリン酸エステル
等を難燃化剤として用いることが行われており、なかで
も三酸化アンチモンが最も有効であることはよく知られ
ている。In order to make vinyl chloride resin flame retardant, antimony trioxide, molybdenum trioxide, zinc borate, barium borate, phosphate esters such as tricresyl phosphate, etc. have traditionally been used as flame retardants. Of these, antimony trioxide is well known to be the most effective.
しかし、三酸化アンチモンを使用する場合得られる難燃
性には限界があり、硬質塩化ビニル樹脂１００部に対し
て約１０部添加した場合が最も難燃性が良く、更に難燃
性を向上させようとして添加量を多くしても難燃性は向
上しない。However, there is a limit to the flame retardancy that can be obtained when using antimony trioxide, and the best flame retardancy is obtained when about 10 parts are added to 100 parts of hard vinyl chloride resin, and flame retardance can be further improved. Even if the amount added is increased, the flame retardance will not improve.
そればかりか、かえって添加量の増加につれて難燃効果
が低くなるという欠点がある。Moreover, it has the disadvantage that the flame retardant effect decreases as the amount added increases.
また、三酸化モリブデン、ホウ酸亜鉛は硬質塩化ビニル
樹脂の熱分解を促進させるため樹脂組成物の熱安定性が
極端に悪くなり、成型・押出し加工法で使用することが
非常に困難である。In addition, molybdenum trioxide and zinc borate accelerate the thermal decomposition of hard vinyl chloride resin, resulting in extremely poor thermal stability of the resin composition, making it extremely difficult to use in molding and extrusion processing methods.
トリクレジルホスフェート等のリン酸エステルは塩化ビ
ニル樹脂の可塑剤として使用するため、硬質塩化バニル
樹脂に対して難燃化に必要な量を添加して用いることが
出来ない。Since phosphoric acid esters such as tricresyl phosphate are used as plasticizers for vinyl chloride resins, they cannot be added to hard vinyl chloride resins in an amount necessary for flame retardation.
本発明者は、上記に鑑み鋭意研究の結果、硬質塩化ビニ

すぐれた防火性能を持った硬質塩化ビニル樹脂組成物を
提供するに至ったものである。In view of the above, as a result of extensive research, the present inventors have found that by incorporating 2 to 60% of polarite powder into a hard vinyl chloride resin composition, it is possible to achieve the following without affecting thermal stability.
We have now provided a hard vinyl chloride resin composition that can be applied to conventional molding and extrusion processing methods and has far superior fireproofing performance compared to antimony trioxide, which is generally considered effective in terms of quantity. be.
本発明に用いられるポーラサイトは天然に産する鉱石で
あり、それを粉砕して使用する。The polarite used in the present invention is a naturally occurring ore, and is used after being crushed.
ポーラサイトの王な化学的成分はホウ素及びカルシウム
で、その割合は一般にＢ２Ｏ３：４０〜４５％、ＣａＯ
：１０〜３０％で、その他Ｎａ、に、Ｍｇ、Ａｔ、Ｆｅ
、Ｓｉの酸化物及び結晶水を含む。The main chemical components of polacite are boron and calcium, and their ratio is generally B2O3: 40-45%, CaO
:10-30%, other Na, Mg, At, Fe
, Si oxide, and crystal water.
このポーラサイトの組成等は産地によって違う場合もあ
るが、本発明には何ら差支えなく使用することが出来る
。Although the composition etc. of this polarite may differ depending on the production area, it can be used without any problem in the present invention.
典型的なポーラサイトとしてはコレマナイト及びウレキ
サイトがあげられ、その紐取の＊＊例を示すと次の通り
である。Typical polarites include colemanite and ulexite, and examples of their strings are shown below.
本発明に用いられるポーラサイト粉末は５０メツシュ篩
下全通の、好ましくは２００メツシユ篩下のものであり
、５０メツシユより大きいものを使用すると難燃効果が
悪くなるばかりか、成形物の強度が低下し、また表面が
荒れて商品価値を低下させるので好ましくない。The polarite powder used in the present invention should pass through a 50 mesh sieve, preferably a 200 mesh sieve. If a powder larger than 50 mesh is used, not only will the flame retardant effect deteriorate, but the strength of the molded product will deteriorate. This is undesirable because the surface becomes rough and the commercial value decreases.
硬質塩化ビニル樹脂組成物中のポーラサイトの添加量は
２〜６０％好ましくは３〜５０％であり、その含有量が
２％より少ない場合は難燃効果が弱く、６０％以上の場
合は樹脂の物性、特に強度が低下するという不利益を生
じる。The amount of polarcite added in the hard vinyl chloride resin composition is 2 to 60%, preferably 3 to 50%; if the content is less than 2%, the flame retardant effect is weak, and if it is 60% or more, the resin The disadvantage is that the physical properties, especially the strength, are reduced.
ポーラサイトの主成分はＢ２Ｏ３及びＣａＯであるが同
じホウ素とカルシウムからなる合成のホウ酸カルシウム
は硬質塩化ビニル樹脂に対して難燃効果をほとんど示さ
ないばかりか知って添加量を増加させると燃焼しやすく
なる。The main components of polarite are B2O3 and CaO, but synthetic calcium borate, which is made from the same boron and calcium, not only shows almost no flame retardant effect on hard vinyl chloride resin, but also causes combustion if the amount added is increased. It becomes easier.
またカルシウムと同族（アルカリ土類金属）であるマグ
ネシウム、バリウム及びストロンチウムのホウ酸塩も難
燃効果を示さない。In addition, borates of magnesium, barium, and strontium, which are homologous to calcium (alkaline earth metals), also do not exhibit flame retardant effects.
