Description
本発明は、軽量化プラスチック靴型の処方とその製造方法に関する。 The present invention relates to a lightweight plastic shoe mold formulation and a method for manufacturing the same.
従来技術は、他の線状鎖低密度ポリエテン（ＬＬ−ＤＰＥ）やエチレンプロピレンゴム（ＥＰＤＭとも称される）などを添加して、発泡効果を向上せず、純高密度ポリエテン（以下、ＨＤＰＥとも称される）だけで、発泡するものが、殆どなく、また、既存の技術では、純ＨＤＰＥ微発泡成形技術に対して、気泡口径の大きさを安定的に制御することが困難であり、それは、ＨＤＰＥの融点が、比較的に高いため、融点により制限が厳しくなり、また、融成物の強度が極めて低いため、加工性が悪くなり、靴型用軽量発泡材料として使用することが非常に難しい。 The prior art does not improve the foaming effect by adding other linear chain low density polyethene (LL-DPE), ethylene propylene rubber (also called EPDM), etc., and pure high density polyethene (hereinafter also referred to as HDPE). In the existing technology, it is difficult to stably control the bubble size with respect to the pure HDPE micro-foaming molding technology. Since the melting point of HDPE is relatively high, the limit becomes severe due to the melting point, and the strength of the melt is extremely low, so the processability is poor and it is very useful as a lightweight foam material for shoe molds. difficult.
既存のＨＤＰＥ＋ＥＶＡ発泡材料やＥＰＤＭ或いはＬＬ−ＤＰＥは、一次発泡法や二次発泡法によって、微発泡材料を生産するが、上記のように、材料物性が、靴を製造することに必要とする靴型に適合しないだけでなく、それとともに、下記の問題点が残される。 Existing HDPE + EVA foam material, EPDM or LL-DPE produce fine foam material by primary foaming method or secondary foaming method, but as mentioned above, the material properties need to produce shoes Not only does it not fit the mold, but it also leaves the following problems.
１、二次閉鎖装置を必要するため、設備コストが高い。 1. Since a secondary closing device is required, the equipment cost is high.
２、殆ど、マスターバッチを製造することが必要とし、また、射出機のネジ杆の中段から、発泡剤を添加するため、生産工程が多くなるだけでなく、生産操作が複雑になり、産出量が低下され、工程時間が長くなる。 2. Mostly, it is necessary to manufacture a masterbatch, and since the foaming agent is added from the middle stage of the screw thread of the injection machine, not only the production process increases, but also the production operation becomes complicated, and the output amount Is reduced, and the process time is increased.
３、金型の変換や発泡割合で二次金型のサイズを算出するため、操作が複雑になり、品質が不安定である。一次発泡法や二次発泡法は、気泡口径をマイクロメートル気泡のサイズ範囲内に制御すること、即ち、口径を１０μｍ〜５０μｍの範囲内、泡孔密度が、１０９〜１０１２個／ｃｍ３に制御することができないため、完成品の品質安定度が悪くなる。 3. Since the size of the secondary mold is calculated based on the mold conversion and the foaming ratio, the operation becomes complicated and the quality is unstable. In the primary foaming method and the secondary foaming method, the bubble diameter is controlled within the micrometer bubble size range, that is, the pore diameter is within a range of 10 μm to 50 μm, and the bubble pore density is controlled to 109 to 1012 / cm 3 . The quality stability of the finished product deteriorates because it cannot be done.
４、マイクロメートル級泡沫プラスチック微粒子から、軽質微発泡ＨＤＰＥに作成する場合、そのような微粒子が、融点が高かい高分子で、空気を被覆し、ＨＤＰＥと混合して添加され、高分子膜の融点が、ＨＤＰＥより高いため、溶融断裂されず、軽量化の目的が実現されるが、価格が高く、格別のエンジニアリング樹脂以外、一般の汎用型製品に適用すると、コストが高くなる。 4. When making from micrometer-class foam plastic fine particles to light micro-foamed HDPE, such fine particles are a polymer having a high melting point, coated with air, mixed with HDPE, and added to the polymer film. The melting point is higher than that of HDPE, so that the purpose of weight reduction is realized without melting and tearing. However, the cost is high when applied to general general-purpose products other than special engineering resins.

本発明は、上記の各種類の試験から分かるように、靴型材質の要求を満足するため、充填材料として、炭酸カルシウム（ＣａＣＯ３）とマグネシウム塩ひげ結晶とを、各５０％の割合で、混合して使用し、それは、炭酸カルシウムが、高剛性で、微細穴発泡ＨＤＰＥ材料の硬度が、気泡の密度が高くなるほど、低下するため、炭酸カルシウムを充填することにより、微細穴発泡ＨＤＰＥ材料の硬度が強化されるが、炭酸カルシウム含量の増加とともに、微細穴発泡ＨＤＰＥ材料の湾曲強度や引張強度及び断裂伸長率が、低下し、特に、断裂伸長率の低下が激しく、また、マグネシウム塩ひげ結晶により、微細穴発泡ＨＤＰＥの引張強度等の諸欠点を解消すれば、炭酸カルシウムである充填材料による欠点が解消され、そのため、確実に、本発明の予期の効果や目的が実現されることができる。 As can be seen from the above-mentioned various types of tests, the present invention satisfies the requirements for shoe-shaped materials, and as a filling material, calcium carbonate (CaCO 3 ) and magnesium salt whiskers are used in a ratio of 50%, It is used as a mixture, because calcium carbonate is highly rigid and the hardness of the microporous foam HDPE material decreases as the density of the bubbles increases, so by filling the calcium carbonate, Hardness is strengthened, but as the calcium carbonate content increases, the bending strength, tensile strength and tear elongation rate of the micro-hole foam HDPE material decrease, especially the tear elongation rate decreases drastically. By eliminating various defects such as the tensile strength of the micro-hole foamed HDPE, the defects due to the filling material which is calcium carbonate can be eliminated. It is possible to effect or purpose of Ming expected to be realized.
