Description

200815189 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 1960s, space technology flourished. Because space is full of electromagnetic waves, in order to block the electromagnetic waves from harming the human body and causing misoperations with related precision instruments, scientists have comprehensively studied the development of electromagnetic shielding materials, due to the height. Resistance to tortuosity and flexibility, the general metal sheet or metal foil can not fully meet the characteristics of the demand, using electroless electron microscopy technology to metallize the molecular organic fiber into a tortuous, flexible, conductive and electromagnetic wave The conductive fabric with the shielding function began to develop. Since the 1980s, due to the rapid development of industrialization such as electronic equipment and information equipment, there is 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 malfunctions caused by external electromagnetic interference caused by precision instruments and equipment in buildings. The human body is affected by possible health effects in an environment filled with electromagnetic waves, and electromagnetic wave shielding materials are now an indispensable material. Generally, it can be used as a kind of electromagnetic wave shielding material. For example, metal copper foil, aluminum foil, iron plate, etc. are well known, and the shielding performance of electromagnetic waves can meet the demand, but the main disadvantages thereof are resistance to tortuosity and poor flexibility. There are many limitations and shortcomings in end use and design, especially the use of coiling and the use of curved facials. There is a very large number of defects in the 114404.doc 200815189. 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 fibers 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 the thickness is about 〇 mm to 0.6 mm. Non-woven metallized into conductive non-woven fabric, different tissue and fiber Danny number, thickness is about 0.12 mms12 mm. After the fabric is metallized by electroless plating, it becomes an electromagnetic wave shielding conductive fabric. The electrical magnetic shielding and electrical conductivity of the fabric can generally meet the demand, but the biggest disadvantage is that it has no compression elasticity, and is used for applications requiring compression and space design restrictions. Great shortcomings and limitations. The electric cloth foam is coated with a hot sol using a conductive cloth, and then has a required width by slitting, and is 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 and foil foam having compressive elasticity. The biggest disadvantage of such products is the high cost of processing engineering. The hot-melt crucible has the danger of infiltrating from the fiber hole to the surface and affecting the conductive function during the coating. The conductive aluminum foil cloth is easy to contact with the surface of the coated heating device during processing. , causing wear or damage, affecting its electrical conductivity, electromagnetic wave shielding performance and weather resistance. Moreover, the minimum cutting thickness of polyurethane foam is 2 mm to 3 mm, and the accuracy of cutting precision is very limited. Generally, the positive and negative tolerances are about 〇·5 mm, and there are 2 error operations when making foam coating. Sexually difficult, for the use of thinner thickness of 0.05 mm to 1.5 mm and the need for thickness accuracy South ό s 用途 用途 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生114404.doc 200815189 The use of commonly known polyurethane foam or polyurethane foam burnt fabrics, knitted fabrics, non-woven fabrics, etc. into a retractable elastic material, and then metallized into a conductive material through the electrolysis of electroplating, its electrical conductivity and Electromagnetic wave shielding performance can generally meet the demand, but the biggest disadvantage of this kind of conductive material and the problem that can not be overcome by using 2 diseases is that the polyurethane foam is poor in weather resistance, easy to embrittle, and easy to be embrittled due to the high hardness of the polyurethane. It is easy to fall off, has poor thickness accuracy, and is easy to fall when foaming and metal scraps are cut during cutting. Even when used inside electronic equipment, it is easy to drop due to poor weather resistance and metal powder. The danger of the road, and the polyurethane foam is generally cut to a small 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 disadvantages of the above-mentioned conductive elastic material, a generally known method of designing a three-dimensional fabric is proposed. For example, Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. 2-3264 has the largest disadvantage of the three-dimensional vertical fiber portion, that is, the intermediate thickness of the support, and the elasticity. The fiber portion is attached to the metal when it is electrolessly plated by wet dipping, and its structural design is very complicated in terms of fabric design. Even worse, the conductive foam is used in the longitudinal direction ( After the cutting, the fabric is designed to cut off some of the fibers and gold chips when cutting, which may cause short-circuit interference to the internal use of electronic and information equipment. Japanese Patent Laid-Open Publication No. 2002-84088, the main drawback of such a product is that it must be accurately cut to the portion without the three-dimensional fiber during cutting, and the defects in the processability and size specifications of the end use are very large and cannot be fully and effectively satisfied. The final use specification requirements, and in the cutting, if cut to the middle, there is a 114404.doc 200815189 body fiber silk (four) copies 'will lose its original design to prevent metal debris falling off' is the special toilet _ The shortcomings of the 3264 bulletin 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 defect for the thickness precision, and the three-dimensional fiber cloth The width and width of the latitudinal point, that is, the thickness of the three-dimensional fiber and the non-stereoscopic fiber are inferior in accuracy. The disadvantage is that the thicker the thickness, the greater the influence on the thickness accuracy, and the more precise thickness is required. The electromagnetic wave shielding the demand for conductive cloth materials has very large defects and limitations, which is necessary for improvement and development.
