Waterproof and breathable membrane assembly and electronic equipment with waterproof and breathable membrane assembly

Abstract

The invention provides a waterproof and breathable membrane assembly and electronic equipment with the waterproof and breathable membrane assembly. The waterproof and breathable membrane assembly comprises a waterproof breathable layer, an adsorption layer and an annular covered edge, wherein the waterproof breathable layer is located on one side, close to the external environment, of the waterproof and breathable membrane assembly; the waterproof breathable layer and the annular covered edge form a containing cavity, and the adsorption layer is located in the containing cavity. When the annular covered edge and the adsorption layer are overlooked, the outer boundary of the adsorption layer is positioned on the inner side of the outer boundary of the annular covered edge. The waterproof performance of the waterproof and breathable membrane assembly is IP67 or IP68, and the breathable rate is 100-6000 ml / min / cm<2>@7 kPa; the specific surface area of the adsorption layer is 700-2000 m<2> / g; the adsorption layer is subjected to edge covering treatment, so that the adsorption layer is basically not stressed in the thickness direction, and the layering phenomenon is avoided. The waterproof and breathable membrane assembly has high waterproofness and high breathability, and can absorb harmful gases such as VOC (volatile organic compounds) and ozone in air, is particularly suitable for being applied to the field of sensor electronic equipment, and ensures the accuracy of sensor transmission signals in the shell.

Problems solved by technology

[0003] In some special fields, people hope that the waterproof and breathable membrane components can play more roles; for example, in the field of sensor electronic equipment, people hope that the waterproof and breathable membrane components can also play the role of purifying the air; The components are very sensitive, and the polluting gases (VOC, ozone and other gases) in the outside air can easily pass through the waterproof and breathable membrane components to have a certain impact on the internal components of the sensor electronic equipment, and then affect the accuracy of the sensor transmission signal or data; but At present, there are no waterproof and breathable membrane components with similar functions on the market, which also limits the development and application of waterproof and breathable membranes to a certain extent.
