Abstract

The invention discloses a lightweight sound-insulating material and a preparation method thereof. This lightweight sound insulation material is made of foam concrete, and the dry material of foam concrete includes the following components: cement, dried sludge, silica fume, fly ash, gypsum powder, slag, shell powder, water reducing agent, Foaming agent; Wherein, foaming agent comprises the following components: polyacrylamide, polyethyleneimine, polyvinylpyrrolidone, hydroxypropyl methylcellulose, triethanolamine, surface hydrophilic modified nano-soil powder, surface active agent. At the same time, a preparation method of the lightweight sound-insulating material is also disclosed. The light-weight sound-insulating material of the present invention has good sound-insulating effect, and at the same time has the advantages of light weight, high strength, heat insulation and waterproof. Application prospects.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a lightweight sound-insulating material and a preparation method thereof. Background technique [0002] Foaming agent, also known as foaming agent, is a substance that can promote foam to form a closed-cell or connected-cell structure. Under certain conditions, through chemical reaction changes or physical methods, it can form a large number of uniform and stable foams in a short period of time. The foaming agent is introduced into the concrete to generate tiny airtight uniform air bubbles inside the concrete, which can form foamed concrete with excellent properties such as light weight, high strength, thermal insulation, heat insulation, and earthquake resistance. However, there are still some problems in the foam concrete at present, including poor slurry stability, uneven air bubbles after hardening, low strength, easy cracking, and easy water absorptio...
