Description

High-tearing-resistance organosilicon leather Technical Field The utility model relates to the technical field of artificial leather, in particular to high-tearing-resistance organic silicon leather. Background The technical scheme includes that the stretch-resistant organic silica leather (CN 119427868A) comprises a hand feeling layer, a first organic silica gel layer, a first base material, a second organic silica gel layer and a second base material which are sequentially arranged, all layers of structures are combined into a whole through the viscosity of the first organic silica gel layer and the second organic silica gel layer, one of knitted fabric, woven fabric or non-woven fabric is selected as the first base material and the second base material, a third organic silica gel layer is additionally arranged between the first organic silica gel layer and the first base material in some embodiments, the stretch-resistant performance of the organic silica leather is improved through a multilayer composite structure, large-scale production is achieved through the processes of coating liquid silica gel with release paper, attaching the base material, stripping the release paper and arranging the hand feeling layer in the preparation process, and the organic silica leather is mainly applied to scenes such as furniture sofa skins, automobile interiors, mobile phone shell films and the like. However, the prior art still has the following technical problems that firstly, the middle base material is only made of common cloth materials, the tearing strength of the common knitted fabric is limited (the tearing strength is less than or equal to 15N/mm), the cloth is thicker, the cloth is difficult to further thin, the severe requirements of high-end fields such as aerospace, electronic packaging and the like on the tearing resistance, deformation resistance and thinness of the material are difficult to be met, the integral failure of leather is easily caused by the breakage of the base material after long-term use, secondly, the outer surface of only one side of the product is an organic silica gel layer, the other side of the product is a base material layer, the base material layer is easily aged due to the corrosion of external environment when being directly exposed or attached to a target object, the surface properties of two sides are inconsistent, the suitability of the product under multiple scenes is limited, and the use requirements of the high-end fields on the double-side protection and uniform stress of the material can not be met. Disclosure of Invention The utility model aims to solve the problems and provides the high-tearing-resistance organic silicon leather. In order to achieve the above purpose, the utility model provides a high-tear-resistance organic silica leather, which comprises a first silica gel layer, a first film layer, a second silica gel layer, a second film layer and a third silica gel layer which are sequentially arranged, wherein the first silica gel layer, the first film layer, the second silica gel layer, the second film layer and the third silica gel layer are sequentially adhered, and the first film layer and the second film layer are respectively one of PI film, carbon fiber or aramid fiber paper.
