ItJX »'This creation is about an insole and midsole The new creation of the finished shoe material, especially refers to a polyolefin plastic as the main basic material, in the process of molding insoles and shoe-sole shoe materials, first apply electron beam irradiation bridge or gamma ray irradiation bridge,-and then During the heating molding process, the supercritical fluid is injected to achieve the expansion effect, so that the finished insole and the finished product of the shoe midsole completely meet environmental protection requirements. [Previous technology] Stupid pressing, because the insole and the sole of the shoe must meet the characteristics of light weight and high cushioning. Therefore, all will go through the molding process of foaming technology. Generally speaking, conventional shoe materials such as insoles and midsoles are manufactured as shown in the first figure. A predetermined proportion of foamed mixed materials (such as EVA plastic, foaming agent, bridging agent and other additives) are used. And other raw materials) are kneaded and mixed, rolled or extruded to form a preliminary embryo with a quantitative reduction ratio, and then put into a heating mold to heat mold and foam into a predetermined size of shoe material, and then cool and shape to become an insole. Or the primary finished product of the midsole shoe material, and then cooperate with other parts to cooperate with subsequent processing. According to investigations, there have been many announcements regarding patents approved for insoles or midsole shoes, such as: 287081, 3570069, 424043, 2727, 47832, etc., and the common points in the manufacturing process are all used. The foaming agent is added as the foaming material for the initial embryo of the shoe material. With the effect of the foaming agent undergoing rapid chemical expansion upon heating, the initial embryo is foamed into a finished shoe sole or midsole. … On the basis of current environmental protection requirements, chemical additives such as foaming agents are given priority to reduce or even eliminate the use. If there are other manufacturing methods that can replace the addition of foaming agents, it will be a brand new product. Manufacturing direction, and when it can be more in line with the requirements of environmental protection. It must be emphasized here that, in terms of environmental protection concepts and requirements of M273235, 丨 仏 .., it does not mean how much the foaming agent itself is added to the manufacturing of shoe materials can cause great harm to the environment. However, when the shoe material is discarded due to damage after a long period of use by the consumer, the foaming agent becomes a burden on environmental protection; from another angle, the disposal of the shoe material without the foaming agent can be treated more than before. Adding foaming agents is more labor-saving and has no environmental concerns. This is based on environmental considerations when discarding. Furthermore, in order to increase the physical properties of the insole and the sole of the shoe, a bridging agent needs to be added before the shoe material is foamed to increase the melting strength of the plastic, so as to increase the temperature range suitable for foaming of the plastic melt. The currently used bridging agents are peroxides, which are decomposed by heat to generate highly activated free radicals. These free radicals cause active sites on the anti-stone reverse chain to form cross-links. Only melted plastics have sufficient melt strength and viscosity to keep the gas from forming bubbles. Under the strict environmental protection requirements, reduction or even elimination of chemical additives is a necessary consideration. In addition to avoiding the pungent odor generated in the manufacturing process, the environmental load generated during disposal or incineration can be reduced. Because the environmental requirements at the time of disposal can also be considered in advance during manufacturing, it is also a contribution to environmental protection. Therefore, we strive to innovate so that the insole or midsole shoe material does not need to add foaming agents and bridging agents during the manufacturing process. Can still produce the expected requirements of the shoe material, that is, research and development efforts for this creation = direction. [New content] The main purpose of this creation is to provide an insole and the finished product of the midsole of the shoe. In the process of molding the molten plastic by heating and molding the shoe material, first apply electron ^ irradiation bridge or gamma ray irradiation bridge , And then inject the supercritical fluid produced by the supercritical gas pressurization system into the secret plastic. When the supercritical fluid is converted into a gas, it will swell in the plastic to achieve a two-inch plastic shoe swell. And the role of the finished shoe material. M273235 The structure of this creation is based on polyolefin plastic ^^ exhaust || beam irradiation bridge or gamma ray irradiation bridge, and then supercritical fluid and high-pressure expansion of the insole and midsole shoe material finished product, with surface layer And the inner layer, which has most of the holes formed by the high-pressure gas pulled plastic staggered and extended in all directions. [Embodiment] About this creation to achieve the above purpose, the following preferred and feasible embodiments are described in detail with the accompanying drawings. As described later, I fully revealed the characteristics and effects of this creation. This creation is for the production of insoles or midsole shoe materials. Therefore, appropriate plastics will still be selected to form S. This creation is based on thallium plastics. The manufacturing process of this creative embodiment is shown in the second figure. After mixing the hydrocarbon plastic, the cross-linking bridge can be used. The effect of the cross-linking bridge can be achieved by electron beam irradiation technology or gamma-ray & ray) irradiation. Technology achieved, these technologies can make plastic reach the side of the bridge. The material is then fed into a hydraulic pressure automatic s machine and heated to form a mold, and in this process, a supercritical fluid is injected (by -supercritical gas augmentation system), #Heating temperature and ultra When the homeland fluid volume reaches a predetermined value. The supercritical fluid is immediately released (depressurized) and the phase of the plastic towel is viewed as a gas and expands uniformly, so that the plastic melts the volume of the body. When the silk mold is finally cooled, the insole of the size is completed. Or the finished product of the midsole of the shoe, which must be advanced-for subsequent processing. The finished product of the insole and insole of this creation, as shown in the three pictures of f, == the finished product of the sheet-shaped shoe material with the edge shape and thickness, can be divided into the surface layer 11 2 ^ 12 in structure. As shown in the fourth figure, in the inner layer 12 two holes 13 and other holes 13 are formed by staggering and extending in various directions by high-pressure gas pulling through the high-pressure gas.
