In order to be sewn into a suitable protective gear, the foaming material provides a flexible 'buffering and tight-feeling property to protect and reduce the risk of injury to the human muscles or joints during exercise, but due to foaming There are many kinds of materials, and the protective gears made with the characteristics of different foaming materials have different advantages and disadvantages. In addition to the basic characteristics of φ, consumers pay more attention to (1) breathable effect, (2) protective gear texture and weight. . To emphasize the breathable effect, it is better to use PU foam. The reason is that the foaming hole of pu foam is open type, and it will be breathable, but its foaming density is too light [generally more than 0_08 per cubic centimeter (g/cm3) below] and the extension elasticity is poor. If the texture and weight of the protective gear are concerned, the rubber foam material of Neoprene is better, the density is higher, the airtight waterproof property is better, and the extension elasticity is good, but the disadvantage It is not air permeable 'often through destructive punching (for example: using a round hole die and stamping method to break the hole and make the Neoprene in the hole, that is, Ne〇prene which forms a destructive aperture in appearance) can borrow 3 M437784 The pore size is ventilated; and the production of Neoprene foam has a high technical level, and often requires two-stage foaming processing. The product has high elongation elasticity (extension elastic fracture is generally more than 200%), and the price is also responsible. If the customer needs different density, It is also necessary to re-produce. The prior art is currently being improved in view of the above disadvantages: (1) U.S. Patent No. 4,832,1, "Orthopedic supports and material for making same", wherein the surgical brace is made of a soft, elastic composite material. It is made of a soft, closed-cell elastomer Ne〇prene rubber material as a base layer, and the Neoprene rubber has a flaky shape, and has a large and deep pore diameter penetrating and dispersed on the surface of the sheet-like Neoprene rubber. A soft, elastic stretchable and porous knit fabric protects the skin and conforms to its base layer. There is also a flexible, elastically stretchable and porous knit fabric that fits over the other side of the base layer. The composite utilizes perforation in a closed cell elastomer to provide porosity and allow air and water to pass through the composite and provide sufficient elasticity to compress a portion of the body surrounding the user under tension. The composite is sufficiently porous to ventilate and improve the air impermeability of Neoprene by the permeability of the pores. (2) US Patent No. US6861379, "BREATHABLE NEOPRENE SUBSTITUTE", reveals a two-layered laminate that is breathable, elastic on all sides, and hydrophilic and non-irritating. It can replace Neoprene. The material is characterized in that it comprises a foam having an elastic and open foamed pore structure, so that the density of the foam is low, so that the foam is compressed to the thickness of the original crucible/4 by pressurization. And on the surface of the pressed foam, a porous and moisture-absorbing M43 / /Μ elastic cloth is used as the inner layer 'and __ a porous and looped elastic cloth as the outer layer, The outer layer is applied to the surface of the foam by means of a fire so that the added foam can increase the density and be breathable.

This composite material includes The central layer, the inner layer and the outer layer. One side of the central layer has continuous grooves, and the grooves are interlaced mesh embossing to promote heat dissipation to the body. Among them, there are many γ-shaped cuts at the grooves. Extending the shell through the central layer and the area of the groove distributed in the layer while retaining sufficient elasticity and density of the center layer material to provide sufficient compression support. This invention cuts the material but fails to be directly as in US483201 The material sees the pore size, but it is cut by the center layer and has a gas permeable effect when stretched. (4) Taiwan Patent No. 079820, which provides a gas-permeable and tough material forming method for sports equipment. The foam is horizontally cut so that the cutting line is parallel to the foaming line of the foam, so as not to damage the foaming line, and then the surface is heated and pressurized to make the The internal structure of the molded body is more compact, and the foaming line is stronger to improve the overall toughness and strength, and is sufficient to replace the high-priced materials currently used, and is applied to sports equipment at a lower cost. The PU foam is heated and pressurized to toughen and enhance the density. (5) Taiwan Patent Publication No. 201006523, which provides a sports protector comprising an inner cloth surface layer, an outer cloth surface layer, and a sandwiched inner layer. a bubble-permeable cotton layer between the surface layer of the cloth and the surface layer of the outer cloth; the foamed cotton layer is formed by 5 M437784 heat and the elongation is greater than 120%, thereby enabling the whole to produce light weight, good air permeability and high Elongation, high strength, etc. This is also to increase the toughness and increase the density by heat-pressing the bubble-permeable cotton. (6) Taiwan Patent Certificate No. 119423, which discloses an elastic breathable cloth and its preparation method, mainly utilizing The rubberized medicine is directly pressed out of the vulcanization molding after being stirred and stirred, and the thickness thereof is controlled by the heating roller to form a low-density high-breathable elastic skin layer, and when the inner lining cloth is attached, the guide slanting plate and the roller are The gap becomes smaller, and the surface of the roller has a deep groove, so that the paste is deeper, so that when the inner lining cloth is fitted, the inner lining cloth and the elastic skin layer have only a very thin adhesive layer, or even only a deep groove. It is sticky, to ensure its breathable function, and the finished product is easy to manufacture when pressing lines and patterns, the defect rate is extremely low, and the color and the layer of any breathable material can be added; this is directly made of rubber as the basic material. (7) Taiwan Patent Certificate No. M336272, elastic cloth breathable structure, - elastic cloth breathable structure, which mainly has ... elastic layer formed by plastic or rubber 'elastic layer': elastic layer - Substrate, the substrate is made of cotton, fiber cloth, knitted fabric, non-woven fabric, nylon cloth or Tedron cloth, etc., and has a number of through holes on the surface of the elastic layer. It is convenient for the user to carry out various sports (4), and the through hole is used to achieve the function of ventilation and ventilation, so that the user can feel dry and comfortable during exercise. This is to use a plastic or rubber foam material to punch holes to form a through hole to improve the breathability. W Taiwan Patent No. 203971 discloses a composite material having an elastic gas permeable effect, which is also a prior invention produced by the applicant for improving the aforementioned different materials. The composite material having the elastic gas permeable effect comprises: a cloth layer and a An elastic layer, wherein the elastic layer is made of a closed-cell foamed material, having a bottom surface attached to the cloth layer, a top surface on the opposite side of the bottom surface, and a plurality of needle-punching penetrating the bottom surface and the top surface And the cloth layer has a substrate and a plurality of piercing elements distributed on the substrate, and the pinning hole is formed by the needle pinning technique, and the piercing element on the cloth layer is passed through the pinning hole of the elastic layer, and The cloth layer and the elastic layer are firmly combined. After the bonding, the needle hole also has a gas permeable effect, so the composite material can have both elastic and air permeable effects, and the side of the elastic layer away from the cloth layer is protruded by the knot-forming element. And showing a visual and tactile similarity to the cloth. The aforementioned patents are also mainly for the gas-permeable effect of the non-breathable material of the closed-cell rubber foam material by means of needle sticking. (9) Taiwan Patent No. 205659, which provides an elastic material having a tapered moisture permeable hole and a method for preparing the same, which is the prior invention of the applicant, wherein the elastic material is provided with a plurality of tapered holes on an elastic base layer, The tapered hole has an inner opening on the inner surface and an outer opening on the outer surface, wherein the inner opening has a larger diameter than the outer opening, and in order to achieve the effect of moisture permeability, the elastic base layer of the invention is further included. a waterproof and moisture permeable layer and a cloth layer on the outer surface, or a waterproof and moisture permeable layer on the inner and outer surfaces of the elastic base layer, and a cloth layer on the inner waterproof and moisture permeable layer, the cloth layer The water-repellent degree is in the level of 1~3. With the innovation of the above-mentioned elastic materials and its preparation method, the elastic material can have the characteristics of softness, elasticity, warmth and the like, and has the functions of moisture permeability and waterproof. The aforementioned patents are mainly developed and improved for non-breathable materials of rubber foamed materials. The prior art composite material for S vines is manufactured by processing with a single foaming material, and the user can select only the material of fixed density and weight, whether it is Neoprene foaming material or M437784 pu foam. It is not possible to have both waterproof and breathable properties, and it is not possible to adjust the overall density of the composite material according to the needs of the user. [New content] The main structure of the prior art composite foamed material is composed by laminating an elastic knitted fabric on both sides of a single-density foam. The t-like structure provides a simple and viscous shock absorbing material. However, since the foam used in the composite material is made of a single material, when the foamed material has a low density, although its gas permeability is good, its ductility and elasticity are poor; if the foamed material has a high density, Its water resistance and exhibitability are good, but the through-rollability is poor, so a single material has only a single-characteristic, and it is limited in its application range. In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a composite foaming material for a protective device which can be selectively used by a user to selectively set a density of a composite foamed material and which is both waterproof and breathable. In order to achieve the above purpose, the composite foam for the protective gear of the present invention is composed of - 14 1 ' ', one or more foams of different densities, and the foam layer M437784
