Description
本発明は、軽量な靴本体を実現し、併せて、耐赤外線用、粘着防止用の射出成形長靴を提供する The present invention realizes a lightweight shoe body, and also provides an injection-molded boot for infrared resistance and anti-adhesion.
元来ポリ塩化ビニルは比重が１．４であり、ポリ塩化ビニルに適した可塑剤・安定剤・充填剤などの配合剤を含有させても１．２程度とポリ塩化ビニル配合物は重い傾向にある。そのため長時間作業の疲労軽減可能な耐油機能をもつ長靴の要望があるが、まだ十分な特性の長靴はできていない（特許文献１参照）。
軽量化する技術としては高分子量ポリプロピレンを有する熱可塑性エラストマーを使用する長靴が知られているが、耐油性・コストに問題がある。発泡剤を含有した長靴も知られているが、裏布との接着・寸法安定性・本体部と底部の接着の問題がある（特許文献２参照）。
Polyvinyl chloride originally has a specific gravity of 1.4, and even if it contains compounding agents such as plasticizers, stabilizers, and fillers that are suitable for polyvinyl chloride, it tends to be heavy with about 1.2. It is in. For this reason, there is a demand for boots having an oil resistance function capable of reducing fatigue during long-time work, but a boot having sufficient characteristics has not yet been made (see Patent Document 1).
As a technique for weight reduction, boots using a thermoplastic elastomer having a high molecular weight polypropylene are known, but there are problems in oil resistance and cost. Boots containing a foaming agent are also known, but there are problems of adhesion to the back fabric, dimensional stability, and adhesion between the main body and the bottom (see Patent Document 2).
長靴はその性質上、水が漏れないよう密封構造となっているため、夏場の屋外作業用途においては、太陽光線中の赤外線波長領域がゴム及び樹脂などの長靴の主たる構成材料が吸収して長靴内の温度が上昇しても逃げ道が無く、炎天下においては外気温＋２０℃にもなるとの報告もある。
そのため着用者は着用部に多量の汗をかき雑菌が繁殖して不衛生となるばかりでなく、不快感から集中力が落ちて作業効率が低下し、労働災害の引き金ににもなりかねない現状がある。また最近では炎天下における作業において太陽光による低温火傷が発生している。
Due to the nature of rubber boots, they have a sealed structure that prevents water from leaking. Therefore, in summer outdoor work applications, the infrared ray wavelength region in the sun's rays is absorbed by the main components of rubber boots and rubber boots. There is also a report that even if the temperature rises, there is no escape route, and the outside air temperature reaches + 20 ° C. under hot weather.
As a result, the wearer sweats a large amount of sweat on the wearing part, and not only hygienic bacteria can grow and become unsanitary, but the concentration can be reduced due to discomfort and work efficiency can be reduced, which can trigger occupational accidents. There is. Recently, low-temperature burns caused by sunlight have occurred during work in hot weather.
射出成形長靴金型は長靴表面の艶出しのため鏡面加工をほどこすことが一般的で、耐油長靴として使用するポリ塩化ビニルは柔軟性・ゴム弾性を付与する目的で多量の可塑剤を含有させる。そのため長靴本体表面部に粘り気が生じ、長靴本体部同士が粘着する問題がある。
粘着防止をする技術としては金型をブラスト加工し表面を粗く仕上げる、または密着面のみ金型をブラスト加工することがある。
ただし専用金型となってしまうため、新たに金型を製作もしくは修正加工しなければならない為、他品種への影響、金型費用が問題となる。
Injection molded boots molds are generally mirror-finished to polish the boot surface, and polyvinyl chloride used as oil-resistant boots contains a large amount of plasticizer for the purpose of imparting flexibility and rubber elasticity. . Therefore, there is a problem that stickiness occurs on the surface part of the boots main body and the boots main part sticks to each other.
Techniques for preventing adhesion include blasting the mold to finish the surface rough, or blasting the mold only on the contact surface.
However, since it becomes a dedicated mold, a new mold has to be manufactured or modified, so the influence on other varieties and mold costs become a problem.

本件発明で用いるガラス微小中空粉体とは、組成はソーダ石灰ケイ酸ガラス(SiO2、Na2O、CaO、B2O3）であり、粒子大きさ１６〜６５μｍ（塩の粒子の１/４程度の大きさ）であり、真密度０．１３〜０．６０ｇ/cm3の形状は真球である。
このようなガラス微小中空粉体は、住友スリーエム株式会社がグラスバブルズという商品名で市販している。
靴の軽量化を考えれば比重が小さいグレードが好ましいが、耐圧強度が小さい傾向にある。
比重０．３８以下のグレードは耐圧強度が弱く、射出成形における射出圧でバルーン（膜）が破壊するため含有量を増やしても比重１．０以下が得られない。
比重０．６グレードは耐圧強度が高いが、比重１．０以下の配合物にするには計算値で５０部以上の含有が必要のため配合における作業性（飛散性、練上がり時間）、成形性（溶融粘度上昇にともなう内部発熱及びシリンダ温度上昇にともなう焼け）が著しく低下してしまい、コストも上がってしまう。
比重０．４２、０．４６のグレードを比較すると０．４２のほうが耐圧強度が高くかつ比重が小さい。
含有量は添加量が多すぎるとガラス微小中空粉体同士がスクリュー回転圧及び射出圧によりぶつかり合いバルーンが破壊するため２５部〜４０部が好ましい。
主な製品を表１に示す。K25、K37、S42XHSをポリ塩化ビニル組成物へ２０部添加し比重を測定したところ、K25は、計算比重０．９、実測比重１．０２、K37は、計算比重０．９９、実測比重１．０３、Ｓ４２ＸＨＳは、計算比重１．０４３、実測比重１．０４、であった。
K25、K37の耐圧強度ではロール練時の負荷による潰れが発生し計算比重が得られないが、S42XHSは計算比重に近い実測比重のため、負荷に耐えうるグレードといえる。
The glass fine hollow powder used in the present invention is a soda-lime silicate glass (SiO 2 , Na 2 O, CaO, B 2 O 3 ), and has a particle size of 16 to 65 μm (1 / of salt particles). The size of true density 0.13 to 0.60 g / cm 3 is a true sphere.
Such a glass micro hollow powder is marketed by Sumitomo 3M Co., Ltd. under the trade name Glass Bubbles.
Considering weight reduction of shoes, a grade with a low specific gravity is preferable, but the pressure strength tends to be small.
Grades with a specific gravity of 0.38 or less have weak pressure resistance, and the balloon (membrane) is broken by the injection pressure in injection molding, so even if the content is increased, a specific gravity of 1.0 or less cannot be obtained.
The 0.6 specific gravity grade has high compressive strength, but it requires a calculated value of 50 parts or more to make a compound with a specific gravity of 1.0 or less, so the workability in the compounding (scattering and finishing time), molding Properties (internal heat generation with an increase in melt viscosity and burning with an increase in cylinder temperature) are remarkably reduced, and the cost is also increased.
Comparing the grades with specific gravity of 0.42 and 0.46, 0.42 has higher pressure resistance and lower specific gravity.
If the content is too large, the glass micro hollow powders collide with each other due to the screw rotation pressure and the injection pressure, and the balloon is destroyed.
The main products are shown in Table 1. When 20 parts of K25, K37 and S42XHS were added to the polyvinyl chloride composition and the specific gravity was measured, K25 had a calculated specific gravity of 0.9, an actual specific gravity of 1.02, K37 had a calculated specific gravity of 0.99 and an actual specific gravity of 1. 03, S42XHS had a calculated specific gravity of 1.043 and a measured specific gravity of 1.04.
With the pressure strength of K25 and K37, crushing due to the load during roll milling occurs and the calculated specific gravity cannot be obtained, but S42XHS can be said to be a grade that can withstand the load because of the measured specific gravity close to the calculated specific gravity.

抗菌剤としては窒素系、窒素硫黄系、窒素硫黄ハロゲン系、環状炭化水素系等の有機系抗菌剤、銀-銅-ゼオライト(Ag-Cu-Zeolite)、銀-亜鉛-ゼオライト(Ag-Zn-Zeolite)等の無機系抗菌剤、有機無機複合系抗菌剤などが挙げられる。
顔料は好みに応じて、市販のものを１種、または２種以上混合して使うことができる。
本発明者はポリ塩化ビニル組成物に上記のガラス微小中空粉体を添加し、種々実験を行った。
フタル酸エステル系可塑剤を加えた平均重合度１１００の標準的なポリ塩化ビニル１００質量部に対して、ガラス微小中空粉体（製品名：S42XHS）を４０質量部まで添加し、比重を測定した結果を図１に示す。
