Problems solved by technology

The control of the internal pore size of the material by the above method mainly depends on the comprehensive and precise control of temperature, material ratio, pressure and gravity, and the process is relatively complicated.
Ordinary fluid filter materials such as activated carbon are also generally designed with a filter mesh structure. Due to structural reasons, the specific surface area of ​​the material is small, and the adsorption and filtration performance of the material cannot be fully exerted.

Abstract

The invention belongs to the technical field of foaming materials, and concretely relates to an environmentally-friendly breathable porous material. The material comprises 3-8 parts of a curing agent, 1-7 parts of a functional material, 2-5 parts of a solid pore forming agent and 0-2 parts of decomposable solid glue. The invention also provides a preparation method of the environmentally-friendly breathable porous material. The preparation method has the advantages of simple control of the size of pores in the material, obtaining of ideal size pores and capillary meso-pores by controlling the dimension and shape of the solid pore foaming agent, and easy development of the material performances of the material due to good connectivity of large and small pores of the material.

Description

technical field [0001] The invention belongs to the technical field of foaming materials, and in particular relates to an environment-friendly and breathable porous material and a manufacturing method thereof. Background technique [0002] Foaming material is a widely used porous structure material, which is widely used in various industries that are closely related to us. Over the years, domestic foaming materials have developed at a rate of 20%, and the output and application fields have continued to expand. In recent years, due to environmental pollution, foaming materials have become more and more widely used in fluid filtration fields such as air filtration and water filtration. In addition, in the field of acoustic wave filtration, foaming materials have become more and more widely used in recent years. [0003] Most of the existing foaming materials on the market are balanced foaming, such as sponge, foaming cement, etc. These foaming materials are generally obtained...
