Description

本発明は、発泡材の製造方法に関するもので、特に、発泡材のシート上に構造が堅固で、かつ立体状花紋または図案のある滑り止め発泡材を作る製造方法を指すものである。   The present invention relates to a method for producing a foam material, and particularly relates to a production method for producing a non-slip foam material having a solid structure and a three-dimensional flower pattern or design on a sheet of the foam material.

一般に、ゴム発泡材はよい弾力性及び減衰特性があるので、常に床板、シートまたはその他敷板に作られ、普遍に日常生活中の振動吸収、防音及び滑り止めに使われているが、ゴム発泡材を利用して作られるシートは自身の強度が弱く、やや大きいせん断応力を受けることができないので、それらは一般に正方形または長方形のシートに作られ、ロール状の発泡材シートに巻き込められ、または、運搬される途中に引きずられて破断することを避ける。   In general, rubber foam has good elasticity and damping characteristics, so it is always made on floor boards, sheets or other floorboards, and is commonly used for vibration absorption, soundproofing and anti-slip in daily life. Sheets made with the use of these are weak in their own strength and cannot be subjected to slightly large shear stresses, so they are generally made into square or rectangular sheets, rolled into a foam foam sheet, or transported Avoid breaking by being dragged in the middle.

この外、発泡材シートの表面は一般に平面状に作られて滑り止めの効果が強調されておらず、一部の製造メーカはこの問題を解決するため、それら正方形または長方形のシートが製造されてから、更に金型を使い、熱加圧方式によってそれら発泡材シートの表面に立体状の凸紋を形成し、発泡材シートの表面の摩擦力を増やしている。ところが、この方法は、製造の過程、時間及びコストを大幅に増やしてしまうが、それら発泡材シートの連続量産及び強度不足の問題を解決することができず、それら発泡材シートの使用範囲も制限される。   In addition to this, the surface of the foam sheet is generally made flat and the anti-slip effect is not emphasized, and some manufacturers manufacture these square or rectangular sheets to solve this problem. From the above, a mold is further used to form a three-dimensional convex pattern on the surface of the foam sheet by a hot press method to increase the frictional force on the surface of the foam sheet. However, this method greatly increases the manufacturing process, time and cost, but cannot solve the problems of continuous mass production of these foam sheets and insufficient strength, and limits the range of use of these foam sheets. Is done.

その後、一部発泡材シートの加工及び製造業者は、量産できないこと及び強度不足の問題を解決するため、それら発泡材シートを作るときに、その上に一層の網布を貼り付けて固定し、それら発泡材シートの強度を効果的に向上するが、この方法は網布が発泡シートとほかの物との直接接触を隔て、そのために、それら発泡材シートが提供する減衰特性及び滑り止め効果は大幅に低下し、あるべき特性をてしまう。   After that, in order to solve the problem of mass production and lack of strength, the processing and manufacturer of some foam material sheets, when making those foam material sheets, affix a single mesh cloth on it, and fix it, Although effectively improving the strength of the foam sheets, this method separates the mesh fabric from direct contact between the foam sheets and other objects, so the damping properties and anti-slip effects provided by the foam sheets are It will be drastically reduced and will have the desired characteristics.

前述の従来の発泡材シートの量産できない、強度不足または滑り止め効果が低下する等の欠点に鑑み、発明人は長期間の努力研究と実験を経た後、遂に本発明の熱可塑性弾性物を利用して立体凸紋のある発泡材を作る方法を開発設計することができ、この方法によって、構造が堅固で、かつ立体的凸紋のある滑り止め発泡材を作り出すことができる。   In view of the above-mentioned drawbacks such as the mass production of the conventional foam sheet, insufficient strength or reduced anti-slip effect, the inventor finally used the thermoplastic elastic material of the present invention after long-term effort research and experiment. Thus, it is possible to develop and design a method for producing a foam material having a three-dimensional convex pattern. By this method, a non-slip foam material having a solid structure and a three-dimensional convex pattern can be produced.

本発明の目的の一つは、熱可塑性弾性物ペレットを利用して発泡材シートを作り、耐高温網布を発泡材シートの表面に貼り付けて固定し、並びに加熱装置によって加熱を行い、発泡材シートが可塑化する程度まで軟化した後、更に表面が均一で複数個の小さい凹溝がある圧縮型ローラまたは圧縮金型をもってローリングまたは圧縮し、すでに塑化した発泡材シートのやや大きい圧力を受ける部分がやや小さい圧力を受ける部分へ移動するようにし、かつ耐高温網布の阻止によって耐高温網布の網孔から突き出され、発泡材シートの表面に均一かつ立体状の凸紋を形成し、このとき、直ちに発泡材シートに冷却処理を行えば、発泡材シートの表面に網布の花紋または図案によって立体状の類似した花紋または図案を形成することができる。   One of the objects of the present invention is to make a foam sheet by using thermoplastic elastic pellets, affix a high-temperature net cloth to the surface of the foam sheet and fix it, and heat by a heating device, and foam After the material sheet is softened to the extent that it is plasticized, it is further rolled or compressed with a compression type roller or compression mold having a uniform surface and a plurality of small grooves, so that a slightly higher pressure is applied to the already plasticized foam sheet. The receiving part moves to a part that receives a little small pressure, and is protruded from the mesh hole of the high temperature resistant net cloth by blocking the high temperature resistant net cloth, forming a uniform and three-dimensional convex pattern on the surface of the foam sheet. At this time, if the foam sheet is immediately cooled, a three-dimensional similar flower pattern or design can be formed on the surface of the foam sheet by using a mesh pattern or design.

本発明のもう一つの目的は、網布を剥離して、発泡材シートの表面に網布の花紋または図案によって立体状の類似した花紋または図案を形成することである。
本発明の更に一つの目的は、冷水を循環する方式をもって圧縮型ローラまたは圧縮金型の表面を低温状態にし、それによって、発泡材シートを立体状凸紋があるように圧縮ローリングまたは成型圧縮を行うと、直ちに発泡材シートを冷却することができ、それら立体状凸紋は迅速に定型され、快速に立体状凸紋のある滑り止め発泡材を作ることができる。 Another object of the present invention is to peel off the net cloth to form a three-dimensional similar flower pattern or pattern on the surface of the foam sheet by the net pattern or pattern.
Another object of the present invention is to cool the surface of the compression mold roller or the compression mold with a method of circulating cold water, thereby compressing the foam sheet with compression rolling or molding compression so as to have a three-dimensional convex pattern. When done, the foam sheet can be immediately cooled, the three-dimensional convex patterns can be quickly formed, and a non-slip foam material with the three-dimensional convex patterns can be made quickly.

本発明は、熱可塑性弾性物ペレットを利用し、発泡材シートを製造し、予定網孔サイズの耐高温網布を発泡材シートの最少一面の表面に貼り付けて固定し、加熱装置によって加熱を行い、発泡材シートが可塑化する程度まで軟化させ、最少一組の金型をもって発泡材シートを加圧し、発泡材シートに耐高温網布が被せてある一面を加圧する金型の表面には均一に複数個の小さい凹溝が設けられ、加圧過程に於いてすでに塑化した発泡材中のやや大きい圧力のかかる部分はやや小さい圧力のかかる部分へ移動してそれら網孔を突き通り、発泡材シートの表面の各網孔に対応する位置に均一かつ立体状の凸紋が形成されることを特徴とする。   The present invention uses thermoplastic elastic pellets to produce a foam sheet, a high-temperature net cloth having a predetermined mesh hole size is affixed to the surface of at least one surface of the foam sheet, fixed, and heated by a heating device. The foam sheet is softened to the extent that it is plasticized, the foam sheet is pressed with a minimum of one set of molds, and the surface of the mold that pressurizes one side of the foam sheet covered with a high-temperature net cloth is applied to the surface of the mold. Uniformly provided with a plurality of small concave grooves, the part of the foam material already plasticized in the pressurizing process moves to the part of the slightly pressurized pressure and passes through these holes, A uniform and three-dimensional convex pattern is formed at a position corresponding to each net hole on the surface of the foam sheet.

本発明の目的、特徴及び方法を、ここに実施例を取り上げ、図面と合わせて詳しく説明する。
本発明の実施例では、熱可塑性弾性物ペレットを使用して伝統的ゴム原料と取って代わり、弾性物ペレットが発泡加工の過程に於いて加熱成型しやすい特徴を利用し、本実施例の滑り止め発泡材を作るものである。本実施例の製造過程に於いて、先ずこの種の熱可塑性弾性物ペレットを金型内に入れて発泡作業を行い、発泡作業が完成したら、金型から発泡材１０を取り出し、並びにばり除去及び修整処理を行い、図１に示すような立方体発泡材１０を形成し、更に実際の厚さの需要によって発泡材１０を複数枚のシート２０に裁断し、あるいは、更に発泡材シート２０の対応側辺を溶接して一巻き連続の発泡材に形成する。 The objects, features and methods of the present invention will now be described in detail in conjunction with the drawings, taking examples here.
In the embodiment of the present invention, a thermoplastic elastic pellet is used to replace the traditional rubber raw material, and the elastic pellet is easily heat-molded in the foaming process. It makes stop foam. In the manufacturing process of the present embodiment, first, this kind of thermoplastic elastic material pellet is put into a mold and foaming work is performed. When the foaming work is completed, the foam material 10 is taken out from the mold, and the flash removal and The cube foaming material 10 as shown in FIG. 1 is formed by the modification process, and the foaming material 10 is further cut into a plurality of sheets 20 according to the actual thickness demand, or further, the corresponding side of the foaming material sheet 20 The sides are welded to form a continuous foam material.

本実施例の製造過程に於いて、図２に示すように、先ず各発泡材シート２１（または一巻の連続する発泡材シート）を加熱装置６０に輸送し、加熱装置６０が発生する高温によって発泡材シート２１を加熱し、発泡材１０が塑化可能な程度まで軟化されたら、更に予定網孔４１サイズのある耐高温網布４０を発泡材シート２１の一側面に貼り付けて固定し、または、実際の需要によって両側表面に貼り付けて固定する。本実施例が実際に実施される場合は、これに局限されず、耐高温網布４０を発泡材シート２１の一側（または両側）表面に貼り付けて固定し、それから、すでに耐高温網布４０が貼り付けてある発泡材シート２１を加熱装置６０へ輸送し、加熱装置６０によって加熱を行い、それを塑化可能な程度まで軟化させてもよい。   In the manufacturing process of the present embodiment, as shown in FIG. 2, first, each foam material sheet 21 (or one continuous foam material sheet) is transported to the heating device 60, and due to the high temperature generated by the heating device 60. When the foam material sheet 21 is heated and softened to such an extent that the foam material 10 can be plasticized, a high-temperature net cloth 40 having a predetermined mesh hole 41 size is further attached to one side surface of the foam material sheet 21 and fixed. Or, it is fixed by sticking to both sides according to actual demand. When this embodiment is actually carried out, the present invention is not limited to this, and the high temperature resistant net cloth 40 is attached and fixed to the surface of one side (or both sides) of the foam sheet 21, and then the high temperature resistant net cloth is already fixed. The foam sheet 21 to which 40 is attached may be transported to the heating device 60, heated by the heating device 60, and softened to such an extent that it can be plasticized.

次に、図３に示すように、更に上圧縮金型（または上圧縮型ローラ）７０及び下圧縮金型（または下圧縮型ローラ）７１をもって各発泡材シート２１を圧縮（またはローリング）する。ここで特に注意するべきことは、発泡材シート２１上の網布４０を被せている一面に加圧する各金型７０の表面には均一に複数個の小さい凹溝８０が設けられ、加圧の過程に於いて、第４図に示すように、すでに塑化された発泡材１０中のやや大きい圧力を受ける部分２２はやや小さい圧力を受ける部分２３（または圧力を受けない部分、すなわち、それら凹溝８０に対応する部分）へ移動し（矢印に示す方向）、この場合、網布４０に阻止されない発泡材は耐高温網布４０の網孔４１を突き通り、発泡材シート２１の表面に網布４０の網孔４１の図案により各網孔４１と対応する位置に立体状の凸紋９０が形成され、その後、直ちに発泡材シート２１に冷却処理を行えば、発泡材１０を構造が堅固でかつ立体状凸紋９０のある滑り止め発泡材に製造することができる。本実施例が実際に実施される場合、滑り止め発泡材を製造した後に網布４０を剥がし取り、発泡材シート２１の表面に網布４０の花紋または図案のような立体状花紋または図案を形成することもできる。   Next, as shown in FIG. 3, each foam sheet 21 is further compressed (or rolled) with an upper compression mold (or upper compression roller) 70 and a lower compression mold (or lower compression roller) 71. It should be particularly noted here that a plurality of small concave grooves 80 are uniformly provided on the surface of each mold 70 that pressurizes one surface of the foam material sheet 21 that is covered with the net cloth 40, In the process, as shown in FIG. 4, a portion 22 in the already plasticized foam 10 that receives a slightly high pressure is a portion 23 that receives a slightly low pressure (or a portion that does not receive pressure, that is, those concave portions. (In the direction indicated by the arrow), in this case, the foam material not blocked by the mesh cloth 40 penetrates the mesh hole 41 of the high temperature resistant mesh cloth 40, and the mesh material is formed on the surface of the foam sheet 21. If a three-dimensional convex pattern 90 is formed at a position corresponding to each net hole 41 according to the design of the net hole 41 of the cloth 40, and then the foam material sheet 21 is immediately cooled, the structure of the foam material 10 is solid. Anti-slip foam with three-dimensional convex pattern 90 It can be produced in. When the present embodiment is actually implemented, after the anti-slip foam material is manufactured, the mesh cloth 40 is peeled off, and a three-dimensional flower pattern or design such as the flower pattern or design of the mesh cloth 40 is formed on the surface of the foam material sheet 21.
