Description of the invention: [Technical field to which the invention pertains] Materials The present invention relates to a multilayer composite having a puncture-preventing function, particularly a slow-resistance puncture material. 5 [Prior Art] In the past, there was a 贱 _ Wei Laihe (4) Yi from the metal plate (four) formula. However, due to such a thick structure, softness and stretchability are very poor, so it has long been abandoned. Most of the multi-layer composite materials on the market that have the function of avoiding puncture are made of multi-layered fabric materials such as cotton, hemp, 10 nylon or polyester, and the puncture-proof effect of this structure is basically the same. The number of layers of material used is proportional, that is, the more layers of the stack 4, the better the effect of puncture prevention, but the more layers used, the thicker the finished product will be, and the softness will be The worse, how to achieve a 15 balance under the two-pole requirement of avoiding puncture and softness and comfort has been a problem for a long time. _ 0This 'In order to be able to manufacture a composite material with a small number of layers and a thin thickness but good puncture resistance, various manufacturers have begun to improve the material and composition to improve the effect of anti-puncture. For example, some products are A fabric layer having a high strength and a high unit price, such as a polyfluorene material, is further impregnated with a resin such as an acrylic resin, which is, for example, an acrylic resin, and then stacked and laminated. Such a product can have a predetermined penetration strength. However, high-strength fabrics are costly, and because of the impregnation, the product is stiffer, softer, and functionally lost. Also, for example, the case of w〇 2004/089143, which is coated on one side of the fabric layer with a hard abrasive 4 201014710 reinforced powder material reinforced polyurethane and/or acrylic resin. Another case is W02006/040679 which is a varnished polyurethane and/or acrylic resin reinforced with a clay material surface that is miniaturized in the form of strontium silicate. However, no matter which the previous case is complicated, it is also trying to increase the hardness of the fabric composition and resist the puncture in a hard-to-hard manner to enhance the penetration resistance.

In order to achieve the above object, the slow-resistance puncture material of the present invention comprises a body 'consisting of a plurality of layers of fabric layers, and the material of the fabric layer may be cotton, hemp, nylon or polyester. a highly elastic PU adhesive layer coated between two adjacent fabric layers to allow two adjacent fabric layers to be adhered, the high elastic pu glue I5 containing asphalt 'the weight of the asphalt contained in the high elastic PU adhesive The percentage is 5-30%. [Embodiment] In order to explain the features and effects of the present invention, an embodiment will be described below in detail. The first figure is a schematic cross-sectional view of an embodiment of the invention. As shown in the figure, the slow-resistance puncture material of the present invention comprises: a body 10, which is composed of a plurality of fabric layers U, and the material of the fabric layer may be cotton, hemp, nylon or material, etc., in this embodiment The medium is 5 201014710. The same elastic silicone layer 12' is applied between two adjacent fabric layers u, so that the adjacent fabric layer U can be adhered to by the high-hybrid pu glue layer 12. The southern elastic PU adhesive layer is composed of pu The weight percentage of the asphalt contained in the pu 5 gum composed of the glue mixed asphalt was 53% by weight. The asphalt in the PU glue is formed by the combination of bridging and bonding, and the combination of the asphalt and the asphalt can change the physical properties of the bonded high-elastic PUg glue, and the elasticity is high. The viscosity of the 11 glue can be greatly improved' and the stretched stretch characteristics are about 10 20 times higher than the conventional pu glue. The following table lists the physical properties of the test for the single cloth before the uncoated high-elastic Pu rubber. Unit Test Method Tensile Strength kg/2.54cm L 80 Tensile Strength W 133 ASTM D5035 Flexibility % L 22 Elongation W 11 ASTM D5035 Tear Strength Kg L 72 Tear Strength W 86 ASTM D2262 Burst Strength Kg/cm2 50+ ASTM 3786 and Tensile Stoll Abrasion Cycles 1.01b 2460 ASTM 3886 6 201014710 In this example, the above table is tested. The single cloth is made up of a fabric layer, the body is a structure of four fabric layers, each fabric layer has a thickness of about 6 mm 1.0 mm, and the total thickness of the body is about 2 4_4.〇mm, two adjacent fabrics. The layers are coated with a highly elastic pu glue layer, wherein the high elasticity 1 >1; the weight percentage of the glue 5 to the total product is 1 〇 2%. The body was tested for its penetration strength of 1232.3 Nt. The following is the structure of the composite of the present invention. The data obtained after the test method of εν12568 is the thickness of the laminated layer. The penetration strength l-7mm 2 291.3 Nt 2.5mm 3 622.3 Nt 3.4mm 4 1232.3Nt The tests listed in the above table As can be seen from the numerical values, the structure of the present invention can exceed the standard value (ll〇〇Nt) required by the general inspection when the number of layers is four, and the thickness of the body can be lower than the expected value of the industry (below 5 mm). Therefore, sufficient puncture resistance can be provided in a state where the thickness is not very thick. In addition, the test can be carried out by testing the high elastic PU adhesive layer in the weight percentage of the total product (also in the test method of EN12568). 7 201014710 Maximum force of sample (Nt) Puncture length (mm) / puncture strength (Nt) Percentage 1 1432.2 0.61/1128 6 10% 2 1425.9 ___0.81/1117.1 10% 3 1526.8 —_0.63/1115.6 12% 4 1580.1 _ 0.62/1128.9 12% 5 1604.6 0.65/119^ ο 14% 6 1684.2 0.83/1182.8 14% 7 1755.9 0.83/1115.8 16% 8 1657.9 L__ 0.60/1115.2 16% It can be known from the above test values, basically high elasticity When the pu glue layer accounts for 10% by weight of the total product, the puncture resistance of the product of the invention exceeds the general inspection standard llOONt value, and the resistance value of the ampere 〇 61 mm 5 exceeds the llOONt ' ii28.6Nt. And® can know that the higher the weight percentage of the high elastic pu glue layer to the total product, the greater the measured value, but the relative softness of the product will also deteriorate with the increase of the high elastic PU adhesive layer. Therefore, the high elasticity 1>1; the weight percentage of the rubber layer to the total product should be in the range of about 1〇-2〇%. 10 Since the body of the present invention is used in a soft manner of viscous and stretchability to slow down or prevent puncture, it is different from the conventional method in which the hard-wearing method is used, so that the product of the present invention can better exert the good stretchability and the like. The softness characteristics are more suitable for use in clothing or footwear. 8 201014710 BRIEF DESCRIPTION OF THE DRAWINGS The first figure is a schematic cross-sectional view of an embodiment of the present invention.
