【考案の詳細な説明】
本考案は発泡ポリエチレン樹脂成形品の表面に多数の凹
凸を有する成形品に関するものである。[Detailed Description of the Invention] The present invention relates to a foamed polyethylene resin molded product having many irregularities on its surface.
発泡台戊樹脂殊に発泡ポリエチレンは包装材、浮体、雑
貨用品等に巾広く使用されているが、物性上粘っこいこ
とから摩擦抵抗が多きく、包装物の開梱時、製品取り出
しが困難であるとか表面のビーズ模様が美観をそんじた
り、曲げに対してビーズの表皮部分から亀裂が入りやす
い等の問題が発生する。Foamed base resin, especially foamed polyethylene, is widely used in packaging materials, floating bodies, miscellaneous goods, etc. However, due to its sticky properties, it has a lot of frictional resistance, making it difficult to remove the product when unpacking the package. Problems arise such as the bead pattern on the surface detracts from the aesthetic appearance, and the beads tend to crack from the outer layer when bent.
本考案は上記欠点に着目−その表面の改質について、種
々の検討を行った結果、表面にビーズ径の０．０２〜２
倍の多数の凹凸を付与した発泡ポリエチレン樹脂成形品
にすることによって、包装用発泡ポリエチレン成形品な
どのすベリが良く所期の目的を達するに好適であること
を見いだした。The present invention focuses on the above drawbacks.As a result of various studies on the modification of the surface, we found that
It has been found that by making a foamed polyethylene resin molded product with twice as many irregularities, it is possible to make a foamed polyethylene molded product for packaging, etc. smooth and suitable for achieving the intended purpose.
発泡合皮樹脂成形品のうち発泡ポリエチレンは特に粘性
が高く梱包を開くときの改良効果が特に著しい。Among foamed synthetic leather molded products, foamed polyethylene has particularly high viscosity, and the improvement effect when opening the package is particularly remarkable.
発泡ポリエチレン成形品としては、ビーズ発泡成形品及
び押出発泡成形品があるが、特にビーズ発泡成形品が最
も好適である。Foamed polyethylene molded products include bead foam molded products and extrusion foam molded products, and bead foam molded products are particularly preferred.
表面の凹凸の大きさはビーズ径の０．０２〜２倍程度が
特に良好である。The size of the surface irregularities is particularly good if it is about 0.02 to 2 times the bead diameter.
小さ過ぎるとすべり効果が少く、大き過ぎると凸部の粘
着が多少起るので好ましくない。If it is too small, the sliding effect will be small, and if it is too large, the protrusions will stick to some extent, which is not preferable.
本考案の実施の１例を図面に基づいて説明する。An example of implementation of the present invention will be described based on the drawings.
第１図は、表面凹凸が出来る工夫をした金型であり、直
径２ｒｒａｎ、深せ２ｒｒｒｍの凹を等間隔に設けた金
型て従来方法と同じ成形を行った。FIG. 1 shows a mold designed to create surface irregularities, and molding was performed in the same manner as in the conventional method using a mold in which concavities of 2 rran in diameter and 2 rrrm in depth were provided at equal intervals.
出来上り製品本体２は表面に直Ｂ２ｍｍ、深さ２ｒｒｖ
ｎの凸部を多数に有するものであるが、第２図に示すこ
とく、弱電器機包装材として使用した場合、段ポールケ
ース３の内側でのすべりが良く、又弱器機商品４とのす
べりが良くなる為梱包及び開梱の作業性が大巾に改善さ
れた。The finished product body 2 has a straight B2mm on the surface and a depth of 2rrv.
Although it has many n convex parts, when used as a packaging material for light electrical equipment, as shown in Fig. 2, it slides well inside the corrugated pole case 3, and it also has a good grip with the light electrical equipment product 4. Due to improved sliding, the workability of packing and unpacking has been greatly improved.
次に他の例を図面に基づき説明すると、第３図に示すご
とく表面を２０メツシユ、高さ２ｒｒａｎの網目模様の
成形品にしたところ、表面のヒース模様がなくなり表面
美観が向上されるはかりてなく折り曲げに対しても、網
目模様でない成形品に比べ強度が増す結果を得た。Next, to explain another example based on the drawings, as shown in Fig. 3, when the surface is made into a molded product with a mesh pattern of 20 meshes and a height of 2 rran, the heather pattern on the surface disappears and the surface appearance is improved. The result was that the strength was increased compared to molded products without a mesh pattern, even when folded.
本考案では、いかなる複雑な成形品でもよく、その全表
面に凹凸をつけるのが好ましいが、表面の一部又はある
面にのみ凹凸をつけてもよい。In the present invention, any complex molded product may be used, and although it is preferable that the entire surface of the molded product be provided with irregularities, it is also possible to provide irregularities only on a part of the surface or on a certain surface.
本考案による成形品は各種包装資材として、又スポーツ
用品、ブイ、その他広汎な用途に使用でき、作業性向上
、美観向上の効果か著しい。The molded product according to the present invention can be used as various packaging materials, sporting goods, buoys, and other wide-ranging applications, and has remarkable effects on improving workability and aesthetic appearance.
