1337937 IX. Description of the Invention: [Technical Field] The present invention relates to the technical field of conductive cloth, and more particularly to a method for producing an elastic conductive cloth having antifouling properties, weather resistance and metal adhesion. [Prior Art]

In the I960s, space technology flourished. Because space is full of electromagnetic waves, in order to block the electromagnetic waves from harming the human body and causing malfunctions to the interference of related precision instruments, scientists have comprehensively studied the development of electromagnetic shielding materials due to their high resistance to tortuosity and flexibility. Demand, the general metal sheet or metal foil can not fully meet the characteristics of the demand, using electroless metallurgy technology to metallize the polymer organic fiber into a conductive fabric with the function of tortuosity, flexibility, conductivity and electromagnetic wave shielding development of. Since the 1980s, the rapid development of industrialization such as electronic equipment and information equipment has become a growing demand for the prevention of electromagnetic interference. In recent years, the rapid growth of electronic devices such as laptop computers, plasma TVs, mobile phones, LCD TVs, and communication devices has become more important to solve the problem of electromagnetic interference, and to prevent the malfunction of external instruments and equipment caused by external electromagnetic waves. Electromagnetic wave shielding materials are now an indispensable material in the environment of electromagnetic waves. Generally, it can be used as a kind of electromagnetic wave shielding material, for example, a well-known metal copper foil, aluminum foil, iron plate, etc., in which the shielding performance of electromagnetic waves can meet the demand, but its main disadvantage is that the tortuosity and the drawability are poor, for the final There are many limitations and shortcomings in the use and design of the application, especially the use of the winding and winding and the use of curved facial products have a very large 114404.doc 1337937 shortcomings. The general metallization of the cloth becomes a very variety of conductive fabrics. For example, the general fabric is metallized to become a conductive fabric, and the different tissues and fiber deniers have a thickness of about 0.07 mm to 0.25 mm. The knitted fabric is metallized to become a conductive knitted fabric, with different microstructures and fiber Dani numbers, and a thickness of about 0.07 mm to 0.6 mm. Non-woven metallized into conductive non-woven fabric, different tissue and fiber Danny number, thickness of about 0.12 〇1〇1 to 1.2 fabric

After electroless plating and metallization, it becomes an electromagnetic wave shielding conductive fabric, and electromagnetic shielding and conductivity can generally meet the demand, but the biggest disadvantage is that it has no compressive elasticity, and there is a great shortage for applications requiring compression and space design restrictions. Disadvantages and limitations.

The conductive cloth foam is coated with a hot-melt adhesive using a conductive cloth, and then formed into a required width by cutting, and then coated with a polyurethane foam having a required thickness and width to form a conductive cloth foam having compressive elasticity. . In addition, a hot-melt aluminum foil cloth is used to make the polyurethane foam into a conductive aluminum foam having compressive elasticity. The biggest disadvantage of such products is the high cost of processing engineering. The hot melt adhesive has the danger of leaking from the fiber hole to the surface and affecting the conductive function during the coating. The conductive ingot cloth is easy to contact with the surface of the coated heating device during processing. Friction causes wear or breakage 'affects its electrical conductivity, electromagnetic wave shielding performance and weather resistance. Moreover, the minimum cutting thickness of polyurethane foam is 2 to 3, and the accuracy of cutting precision is very limited. The normal positive and negative tolerance is about 〇5 mm' and there are 2 errors when making foam coating. The workability is extremely difficult, and there are great disadvantages and limitations for the design use where the thickness of the thin 0.G5 is required to be used in mm and the thickness is required to be high. 114404.doc I use the well-known polyurethane foam or polyurethane foam burnt fabric, knitted fabric, non-woven fabric, etc. to become a compressive elastic material, and then metallized into a conductive material through electroless key, its conductivity and electromagnetic wave shielding performance can generally It meets the demand, but the biggest disadvantage of this kind of conductive material and the problem that can not be overcome by the user's disease is that the polyurethane 6 is foaming Zhao, because it is a polyurethane sulphate, it has poor ten-time, easy embrittlement, metal The film is easy to be brittle and inferior, the thickness is 4 degrees, the foam and metal scrap are easy to fall when cutting, and even more: when used inside the electronic sigh, the weather resistance is poor and the metal powder is easy to fall. The danger of electronic sighing short circuit 'and polyurethane foam is the most common knife! With a thickness of 2 mm to 3 mm, the demand for thinner and lighter electronic and communication equipment that cannot meet the characteristics of thin and light materials is the biggest drawback and limitation. In order to improve the shortcomings of the above-mentioned conductive elastic material, the generally known three-dimensional weaving t method is proposed in the 疋, such as the Japanese patent special opening 卜 _ _ public /, the biggest disadvantage 疋 stereo vertical fiber part, that is, the support intermediate thickness Fiber of 丨.卩 'When using wet impregnation method, electroless metallization = metal adhesion will be attached' and its structural design is not complicated in terms of fabric design. Moreover, the general conductive foam is used in the longitudinal direction. ) The j fabric 2 is easy to cut off some of the fibers and metal scraps when cutting. Dong Shi is in danger of short-circuit interference in the internal use of electronic and information equipment. Japanese Patent Special 2()() 2_84 () Bulletin No. 88, this product is mainly lacking i must be accurately cut to the part without the three-dimensional fiber, the final use of 2 processing and size specifications are very large, can not effectively complete the end-use specifications And in the cutting, if you cut the part of the body filaments 114840.doc 1337937 in the middle, you will lose the original design to prevent (4) the function of falling debris, that is, with the special opening 2001-3264 The disadvantages are the same, and even more so due to the influence of the take-up tension during the weaving and processing of the three-dimensional fiber cloth, the supporting force and the support type of the middle upright fiber have a very large disadvantage for the thickness precision, and the width of the three-dimensional fiber cloth The width of the wide latitude to different points, that is, the thickness of the three-dimensional fiber and the non-stereofilament are poor. The disadvantage is that the thicker the thickness, the greater the influence on the thickness accuracy.

The more demanding electromagnetic wave shielding conductive cloth materials for thickness accuracy, there are very large defects and limitations, and f is necessary for development and development.
