Description
本発明は、射撃用ターゲットクレー組成物に関する。 The present invention relates to a target clay composition for shooting.
従来、クレー射撃で広く使われているターゲットは、主に石油ピッチから作られていた。しかしながら、発ガン性が危惧されるベンゾピレンが含まれており、環境に影響を及ぼす問題があった。 環境に影響を及ぼさないものとして、特許文献1(国際公開01/53231A1パンフレット)には、クレー射撃ターゲット製造用組成物として、非金属鉱物の粉末、あるいは貝殻の粉末、あるいは金屑;65〜85質量%、接着剤;5〜13質量%、石膏;0.3〜2質量%、比重調整剤;2〜6質量%、酸化鉄;0〜1質量%、シリケート;3〜6質量%、粘土;0〜3質量%からなる組成物が開示されている。
しかしながら、この組成物によって得られるターゲットは、出割れ(クレー放出機で射撃用クレーを発射する時に、その衝撃で射撃用クレーが破壊してしまう現象。集中して射撃用クレーの発射を待っている射手から最も嫌われる。)が多く、破砕性も不十分であるという欠点があったり、さらに成形時の材料の流動性に問題があった。
However, the target obtained with this composition is cracked (a phenomenon in which the shooting clay is destroyed by the impact when the shooting clay is fired with a clay discharger. Most of them are hated by archers), and there are drawbacks such as insufficient crushability, and there is a problem in the fluidity of the material during molding.
本発明は、従来の主に石油ピッチから作られた射撃用クレーで問題であった、環境に影響を及ぼすことがなく、さらに出割れが少なくかつ破砕性が良好であり、成形時の材料の流動性が良好な射撃用クレー組成物を提供することを目的とする。 The present invention has been a problem with conventional shooting clay made mainly from petroleum pitch, has no impact on the environment, has less cracking and has good crushability, and is suitable for the material at the time of molding. An object is to provide a shooting clay composition having good fluidity.
本発明者は、前記課題を解決するために鋭意検討を行った結果、繊維状物質類を非金属鉱物に混合することによって、上記課題を解決出来ることを見いだし本発明をなすに至った。
すなわち、本発明は下記の通りである。
(1)少なくともフィラーとバインダーとからなる射撃用クレー組成物であって、前記フィラーが、88.0〜99.8質量%の非金属鉱物類及び0.2〜12.0質量%の繊維状物質類とからなることを特徴とする射撃用クレー組成物。
(2)繊維状物質類が、ウォラストナイトであることを特徴とする(1)記載の射撃用クレー組成物。
(3)バインダーが、金属石鹸類を2.0〜98.0質量%含有することを特徴とする(1)または(2)記載の射撃用クレー組成物。
(4)金属石鹸類が、ステアリン酸亜鉛であることを特徴とする、(3)記載の射撃用クレー組成物。
(5)バインダーが、石油ワックス類を2.0〜50.0質量%含有することを特徴とする(1)から(4)のいずれかに記載の射撃用クレー組成物。
(6)バインダーが、ロジンエステル類を5.0〜95.0質量%含有することを特徴とする(1)から(5)のいずれかに記載の射撃用クレー組成物。
As a result of intensive studies to solve the above problems, the present inventor has found that the above problems can be solved by mixing fibrous substances with non-metallic minerals, and has reached the present invention.
That is, the present invention is as follows.
(1) A shooting clay composition comprising at least a filler and a binder, wherein the filler is 88.0 to 99.8% by mass of non-metallic minerals and 0.2 to 12.0% by mass of fibrous material. A clay composition for shooting characterized by comprising substances.
(2) The firing clay composition according to (1), wherein the fibrous substance is wollastonite.
(3) The clay composition for shooting according to (1) or (2), wherein the binder contains 2.0 to 98.0% by mass of metal soaps.
(4) The shooting clay composition according to (3), wherein the metal soap is zinc stearate.
(5) The clay composition for shooting according to any one of (1) to (4), wherein the binder contains 2.0 to 50.0% by mass of petroleum wax.
(6) The clay composition for shooting according to any one of (1) to (5), wherein the binder contains 5.0 to 95.0% by mass of rosin esters.
本発明は出割れが少なくかつ破砕性が良好であり、成形時の材料の流動性が良好な射撃用クレー組成物を提供出来る効果を有する。 INDUSTRIAL APPLICABILITY The present invention has an effect that it can provide a shooting clay composition with few cracks and good crushability and good flowability of a material during molding.
本発明について、特にその好ましい形態を中心に、以下具体的に説明する。
本発明において非金属鉱物類とは、アルカリ土類金属のリン酸塩、炭酸塩、硫酸塩やアルカリ土類金属の水酸化物やアルミの珪酸塩等から構成されるものであり、例えば重炭酸カルシウムやタルクや珪砂やカオリンや消石灰や生石灰や高炉スラグやこれらを単独で使用しても良いし、2種類以上を混合して使用しても良い。本発明において繊維状物質類とは、珪酸カルシウムや炭酸カルシウムや珪酸ナトリウムの繊維状物質や天然植物や合成樹脂の繊維状物質のことを指す、例えばウォラストナイトやウィスカやガラスファイバーやパルプや古紙解砕粉やビニロン繊維やポリエステル繊維やナイロン繊維やこれら単独で使用しても良いし、2種類以上を混合して使用しても良い。
The present invention will be specifically described below, particularly focusing on preferred forms thereof.
In the present invention, the non-metallic minerals are composed of alkaline earth metal phosphates, carbonates, sulfates, alkaline earth metal hydroxides, aluminum silicates, etc. Calcium, talc, silica sand, kaolin, slaked lime, quicklime, blast furnace slag, and these may be used alone, or two or more kinds may be mixed and used. In the present invention, fibrous substances refer to fibrous substances such as calcium silicate, calcium carbonate and sodium silicate, and fibrous substances such as natural plants and synthetic resins. For example, wollastonite, whisker, glass fiber, pulp and waste paper The pulverized powder, vinylon fiber, polyester fiber, nylon fiber, or these may be used alone, or two or more kinds may be mixed and used.
本発明においてフィラーに88.0〜99.8質量%の非金属鉱物類を使用する。
さらに好ましくは90.0〜99.5質量%、最も好ましくは90.5〜99.0質量%使用する。88.0質量%未満だと破砕性が悪く、99.8質量%を超えると出割れが多くなる。
