Problems solved by technology

[0003] Now urban sound absorption is still a serious problem. Urban noise seriously affects people's lives. In a noisy environment, people's physical health will continue to decline, and the efficiency of learning and work will continue to decrease. Therefore, noise prevention has always been It is a problem that people are constantly trying to solve, and some building materials with sound-absorbing functions have been derived from this, but these materials often have poor recycling rates, high production costs and complicated processes.

Abstract

The invention relates to an open-cell foam basalt material and a manufacturing method thereof and belongs to the field of basalt materials. According to the open-cell foam basalt material, the problems that an existing sound absorbing material has poor cycle utilization and complicated process are solved, and the open-cell foam basalt material is provided. The open-cell foam basalt material is formed by polymer sponge adsorbing basalt slurry and baking, the basalt slurry is made of, by mass content, 60-80% of basalt powder, 5-10% of dispersing agent and 10-20% of flux, the total mass percentage of each raw material is 100%, and the solid content in the slurry is 40-60%. The method includes the steps of pretreatment of organic body polymer sponge, preparation of basalt slurry, preparation of open-cell foam basalt green body, sintering of open-cell foam basalt and the like to prepare the open-cell foam basalt material. The open-cell foam basalt material can be applied to the processing and utilization of sound absorbing materials.

Description

technical field [0001] The invention relates to a basalt material, in particular to an open-cell foam basalt material and a production method. Background technique [0002] Noise damages the sensory hair cells of the ear's acoustic organs. Once the sensory hair cells are damaged, they will never recover. Sensitive hair cells with high frequencies are most vulnerable to noise damage. Therefore, most people's hearing has already been damaged by noise. If you don't have a hearing test, you often don't realize it, and your hearing will continue to weaken without knowing it. [0003] Now urban sound absorption is still a serious problem. Urban noise seriously affects people's lives. In a noisy environment, people's physical health will continue to decline, and the efficiency of learning and work will continue to decrease. Therefore, noise prevention has always been It is a problem that people are constantly trying to solve, and some building materials with sound-absorbing functi...
