Problems solved by technology
The irregularity and three-dimensionality of the bubbles make it have excellent sound insulation properties; but there are still some limitations in absorbing sound waves. Usually, it is necessary to drill a certain number of through holes through the aluminum plate on the foamed aluminum plate to increase and improve the sound wave. Absorption effect; resulting in increased processing steps and increased production costs
[0003] In addition, the production of aluminum foam board is to add a foaming agent to the aluminum metal in a high-temperature molten state, and after stirring, it is coo...

Abstract
The invention relates to a sound insulation material and a manufacturing process thereof as well as a sound insulation board made of porous foamed aluminum materials and a manufacturing process thereof, aiming to solve the technical problems that the provided foamed aluminum particle board is required to have the characteristics of good sound insulation and sound wave absorption effects, intensity conforming to operational requirements and lower cost, and the provided process is required to have the characteristics of simple working procedures, convenient manufacturing and higher production efficiency. The invention has a technical scheme that the compound foamed aluminum particle board is a flat board formed by the mutual adhesion of foamed aluminum particles, wherein the surface of at least one plane of the flat board is compounded with a screen board or a perforated board. The manufacturing process is carried sequentially according to the following steps of: 1. crushing: crushing waste foamed aluminum materials into foamed aluminum particles with the sizes of 1-6mm in a crushing machine; 2. laminating and molding: uniformly mixing the foamed aluminum particles and adhesive according to the weight ratio of 1:3-7, then pouring in a mold, and laminating and molding in a press; and 3. drying the adhesive, and heating up to bake the molded board so as to dry and solidify the adhesive.
Description
technical field [0001] The invention relates to a sound-insulating material and its manufacturing process, in particular to a sound-insulating board made of porous aluminum foam material and its manufacturing process. Background technique [0002] Sound insulation and noise reduction is an important issue facing modern society; sound insulation and noise reduction plays an important role in the fields of transportation, construction, military, manufacturing and human health. The new material that has emerged in recent years - aluminum foam board, is formed by the disorderly arrangement of many closed bubble holes, and the isolation film between adjacent bubble holes is an aluminum material that is melted at high temperature and foamed and then cooled and solidified. The irregularity and three-dimensionality of the bubbles make it have excellent sound insulation properties; but there are still some limitations in absorbing sound waves. Usually, it is necessary to drill a cert...
