Description
【0001】
【発明の属する技術分野】
本発明は練り消しに関し、更に詳しくは、軽量で、練り易く、且つソフトで練り心地の良好な練り消しに関する。
【0002】
【従来の技術】
従来、練り消しは練ったり、引き伸ばしたりして造形を楽しむことを主たる目的とするものであるが、今日、その興趣性を高めるために、芳香や、各種果物や食物の香りを発するもの、練ったり、引き伸ばしたりしているうちに色が変色するもの、等が実用化されている。
【0003】
しかしながら、練り消しは主として年少の子供に向けられているにも拘らず、軽量性や練り易さ、練り心地、更には、使い方の多様性化については、これまで殆ど注目されていないのが実情である。
【0004】
【発明が解決しようとする課題】
本発明は、かかる実情に鑑み、軽量で、練り易く、且つ練り心地が改善され、多様な使い方の可能な練り消しを提供するものである。
【0005】
【課題を解決するための手段】
本発明者らは上記課題を解決するべく鋭意研究の結果、練り消し基材に、特定の中空微小球を配合することにより、所期の目的が達成されることを見い出し、本発明に到達した。
【0006】
即ち、本発明は粘弾性基材に、熱可塑性ポリマーの表面を不活性無機粉体でコーティングしたハイブリッド中空微小球を配合してなることを特徴とする練り消しを内容とする(請求項1)。
【0007】
好ましい態様としては、上記ハイブリッド中空微小球の配合量が粘弾性基材100重量部に対し10〜300重量部である練り消しである(請求項2)。
【0008】
より好ましい態様としては、上記ハイブリッド中空微小球の配合量が粘弾性基材100重量部に対し10〜250重量部である練り消しである(請求項3)。
【0009】
【作用】
本発明の練り消しは、熱可塑性ポリマーの表面を不活性無機粉体でコーティングしたハイブリッド中空微小球を配合したので、軽量化されるとともに、ソフトで練り易さ、練り心地に優れ、更には、従来の使い方の練り、引き伸ばしの他に、様々な使い方が可能となる、等多くの特徴を有する。
【0010】
例えば、軽く、ふわふわしたソフトな手触り感であるので、手の小さい年少の子供や手の力の弱い老人でも楽しむことができ、また軽く、ふわふわした感じで衝撃吸収力が強いので投げつけた時の危険性も小さい。また、水に浮く練り消しが得られるので、所望のキャラクターや動物の形に造形した後、水槽や浴槽に浮かせて楽しんだり、軽い練り消しと従来の重い練り消しとを混ぜ合わせ、両者の混合割合と沈み具合(又は浮き具合)を体感、学習する知育玩具としても利用できる。
【0011】
更に、軽量化されているので、体積当りの単価が安くなり、同一体積当りの輸送単価も安くなり、また、半製品や製品の持ち運びが容易である。
【0012】
【発明の実施の形態】
本発明に用いられる粘弾性基材としては、ゴム、樹脂、エラストマー等の粘弾性を有する物質が用いられる。
【0013】
ゴム系基材としては、例えば、IIR(ブチルゴム)、IR(イソプレンゴム)、SBR(スチレン−ブタジエンゴム)、BR(ブタジエンゴム)、EPM(エチレンプロピレンゴム)、EPDM(エチレンプロピレン三元共重合体)、アクリルゴム、ポリイソブチレン、NR(天然ゴム)が挙げられ、これらは単独でもよいが、好ましくは2種以上組み合わせて用いられる。更に、練り消しの機能を損なわない範囲で、スチレン系樹脂、オレフィン系樹脂、エチレン−酢酸ビニル系樹脂、塩化ビニル系樹脂等の他の基材と組み合わせても差し支えない。
【0014】
本発明に用いられる、熱可塑性ポリマーの表面を不活性無機粉体でコーティングしたハイブリッド中空微小球としては、例えば、ポリアクリロニトリルを主成分とする高分子中空微小球体の表面が、炭酸カルシウム、タルク、酸化チタン等の粉体でコーティングされたものが市販され、具体的には、松本油脂製薬株式会社製のマイクロスフェアーMFLシリーズ「100CA」、「80CA」、「80GCA」、「100SCA」等が挙げられる。これらは単独で又は必要に応じ2種以上組み合わせて用いられる。
【0015】
上記ハイブリッド中空微小球の配合量は、粘弾性基材100重量部に対し10〜300重量部が好適である。ハイブリッド中空微小球の配合量が10重量部未満では本発明の効果が不十分となり、一方、300重量部を越えると練り時間が長くなる傾向があり、また、そのためにハイブリッドバルーンが潰れるおそれがある。従って、より好ましくは、粘弾性基材100重量部に対し10〜250重量部である。
尚、充填剤を配合しない場合は、練りや引き伸ばし性の面からは30重量部以上使用するのが好ましい。
【0016】
本発明の練り消しは、更に、必要に応じて、プロセス油、流動パラフィン、菜種油、綿実油等の軟化剤、重質炭酸カルシウム、軽質炭酸カルシウム、シリカ、珪藻土、酸化マグネシウム、タルク、セリサイト、石英粉末、モンモリロナイト、ホタテ、カキ、しじみなどの貝殻粉末などの充填剤、有機中空粒子、無機中空粒子及び有機・無機顔料、染料などの着色材、香料、安定剤、滑剤、酸化防止剤、紫外線吸収剤、防カビ剤などの他の添加物も適宜任意に使用することも可能である。
【0017】
上記の如き成分からなる練り消しは、混練され、プレス成形、射出成形、押出成形等により成形され、所定の寸法に裁断されて製品とされる。
【0018】
【実施例】
以下、実施例及び比較例に基づいて本発明を更に詳細に説明するが、これらは本発明の範囲を何ら制限するものではない。

[0003]
However, despite the fact that kneading is mainly aimed at younger children, there has been little attention so far regarding lightness, ease of kneading, kneading comfort, and diversity of usage. It is.
[0004]
[Problems to be solved by the invention]
In view of such circumstances, the present invention provides a kneading agent that is lightweight, easy to knead, has improved kneading comfort, and can be used in various ways.
[0005]
[Means for Solving the Problems]
As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that the intended purpose is achieved by blending specific hollow microspheres with the kneaded base material, and have reached the present invention. .
[0006]
That is, the present invention includes a kneading characterized in that hybrid hollow microspheres in which the surface of a thermoplastic polymer is coated with an inert inorganic powder are blended with a viscoelastic substrate (claim 1). .
[0007]
As a preferred embodiment, the hybrid hollow microsphere is mixed with 10 to 300 parts by weight based on 100 parts by weight of the viscoelastic substrate (claim 2).
[0008]
As a more preferable embodiment, the hybrid hollow microsphere is mixed with 10 to 250 parts by weight with respect to 100 parts by weight of the viscoelastic substrate (claim 3).

Further, since the weight is reduced, the unit price per volume is reduced, the unit price for transportation per unit volume is also reduced, and the semi-finished product and the product are easy to carry.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
As the viscoelastic base material used in the present invention, a viscoelastic substance such as rubber, resin, or elastomer is used.
[0013]
Examples of the rubber base material include IIR (butyl rubber), IR (isoprene rubber), SBR (styrene-butadiene rubber), BR (butadiene rubber), EPM (ethylene propylene rubber), EPDM (ethylene propylene terpolymer). ), Acrylic rubber, polyisobutylene, and NR (natural rubber). These may be used alone or in combination of two or more. Furthermore, it may be combined with other base materials such as a styrene resin, an olefin resin, an ethylene-vinyl acetate resin, and a vinyl chloride resin as long as the kneading function is not impaired.
[0014]
As the hybrid hollow microspheres coated with an inert inorganic powder on the surface of a thermoplastic polymer used in the present invention, for example, the surface of a polymer hollow microsphere mainly composed of polyacrylonitrile is composed of calcium carbonate, talc, Those coated with powders such as titanium oxide are commercially available.

About each sample, the lightness and workability (a kneading condition, a stretching condition, a touch) were measured and evaluated by the following method. The results are shown in Table 2.
[0022]
The weight of the lightweight kneaded sample was expressed as a value divided by the volume.
[0023]
The stickiness and feel when a workable kneaded sample was kneaded or stretched were evaluated according to the following criteria.
(Double-circle): There is no feeling of bleed and stickiness, and the touch is also good.
○: There is no bleed and stickiness, and the touch is good.
□: Although there is no bleeding feeling, there is a sticky feeling and the touch is also poor.
Δ: There is no bleed and stickiness, but the fabric is deformed over time.
X: There is a sticky feeling, and the fabric is also deformed with time.
[0024]
[Table 2]
[0025]
Comparative Examples 1-4
Except that the hybrid hollow microsphere “MFL-100SCA” was not used, the same operation as in Examples 1 to 4 was performed, and the characteristics of the obtained kneaded samples were measured and evaluated. The results are shown in Table 3.
[0026]
[Table 3]
[0027]
Examples 5-10
Except having changed into the mixing | blending shown in Table 4, it operated similarly to Examples 1-4, and measured and evaluated the characteristic of the obtained kneaded sample. The results are shown in Table 4.
[0028]
[Table 4]
[0029]
Comparative Examples 5-10
Except that the hybrid hollow microsphere “MFL-100SCA” was not used, the same operation as in Examples 5 to 10 was carried out, and the properties of the obtained kneaded samples were measured and evaluated. The results are shown in Table 5.
[0030]
[Table 5]
[0031]
Examples 11-16, Comparative Examples 11-15
Except having changed into the mixing | blending shown in Table 6, it operated similarly to Examples 1-4, and measured and evaluated the characteristic of the obtained kneaded sample. The results are shown in Table 6. In Example 16, since there are many hybrid hollow microspheres, some of them are broken during kneading and are slightly heavier.
[0032]
[Table 6]
[0033]
From Table 2 to Table 6, by blending hybrid hollow microspheres whose surface is coated with an inert inorganic powder, the weight of the thermoplastic polymer is reduced and processability, that is, easy to knead, bleed and stickiness It can be seen that there is no feeling and a soft and comfortable kneading can be obtained.
[0034]
Further, as is apparent from Table 6, when cross-linked styrene-acrylic hollow particles [JSR SX866 (A)] are used instead of the hybrid hollow microspheres, as shown in Comparative Examples 14 and 15, stickiness There is a bad touch and the effect of weight reduction is small. Furthermore, when organic hollow spheres (Microsphere F-80ED) are used, as shown in Comparative Examples 11 to 13, the weight reduction is sufficient, but the powder rises during blending and kneading, handling and work There is an environmental problem.
[0035]
Examples 17-22
As shown in Table 7, the same operation as in Examples 1 to 4 was conducted except that light calcium carbonate was not used, and the properties of the obtained kneaded samples were measured and evaluated. The results are shown in Table 7.
[0036]
[Table 7]
[0037]
From Table 7 above, it can be seen that even when no filler is used, kneading with good processability is obtained, and since this kneading does not contain a filler, it is surprisingly light in weight.
[0038]
【The invention's effect】
As mentioned above, the kneading blended with the hybrid hollow microspheres of the present invention coated with an inert inorganic powder on the surface of the thermoplastic polymer is lightweight, soft, easy to knead, and excellent in kneading comfort. .
[0039]
In addition, the kneading of the present invention has a light and soft hand, so it is easy to handle even for young children and the elderly, and it is very light so there is little danger. Further, it can be floated in water, and it can be used as an educational toy for experiencing and learning the sinking condition (or floating condition) by mixing the light kneading of the present invention and the conventional heavy kneading.
