Abstract

The invention discloses a foamed basalt environment-friendly sound-insulation material and a manufacturing method thereof. The foamed basalt environment-friendly sound-insulation material is mainly prepared from the following raw materials: basalt ores, nano hollow microbeads, gypsum, waste glass powder, a foaming agent, a fluxing agent, a foam stabilizer, a dispersing agent and auxiliary materials. The manufacturing method comprises the following steps: pulverizing, mixing, drying, foaming, cutting, polishing the finished product and the like. The method is simple and easy to operate. The sound insulation capacity of the prepared foamed basalt environment-friendly sound-insulation material is 28-69%, and the porosity is 90-96%. The method is simple and easy to operate. The prepared finished product has the advantages of no toxicity, no radiation, low heat conductivity coefficient, favorable sound insulation capacity, moth resistance, corrosion resistance, stable and favorable chemical properties and the like. The main raw material basalt has wide mineral deposit distribution in China as a volcanic rock, and thus, is easy to acquire and low in price. Therefore, the obtained product has high cost performance. The foamed basalt environment-friendly sound-insulation material has the environment-friendly effect in the aspects of manufacturing and use.

Description

technical field [0001] The invention relates to an environment-friendly sound-insulating material, in particular to a foamed basalt environment-friendly sound-insulating material and a production method thereof. 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 insulation 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 constantly want to...
