Manufacturing method of wall sound insulation material

Abstract

The invention discloses a manufacturing method of a wall sound insulation material, and relates to the related field of wall sound insulation material manufacturing. The invention aims at solving theproblems that in the prior art, sound insulation materials prepared after materials are combined are insufficient in adhesiveness, and cracks, stripping and the like can occur when the materials act on the wall. The method comprises the following steps: separating barks and stems of obtained branches to prepare crushed plant fibers; preparing foam concrete, and crushing the foam concrete; preparing silicon dioxide sol, and adding a silane coupling agent, an expanding agent and an antioxidant into the silicon dioxide sol; adding the obtained lower-layer static precipitate and the obtained lower-layer filter residue into a wet mixture, and mechanically stirring and mixing to obtain a sound insulation material matrix; preparing a sound insulation material mixed filler; adding the sound insulation material matrix into the sound insulation material mixed filler; and extruding, dehydrating and drying the plant fibers, adding the plant fibers into the mixture, and mechanically stirring and mixing.

Description

technical field [0001] The invention relates to the field related to the manufacture of wall sound-insulating materials, in particular to a method for manufacturing wall-surface sound-insulating materials. Background technique [0002] Sound insulation refers to the isolation, isolation, separation, etc. of sound or noise through certain objects, so sound insulation materials are needed. The number of decibels related to the incident sound energy on one side of a material relative to the transmitted sound energy on the other side is the sound insulation of the material, usually expressed by the symbol R (dB). Sound insulation materials refer to a class of materials, components or structures that can block sound transmission or reduce transmitted sound energy, and are characterized by heavy weight and high density, such as steel plates, lead plates, concrete walls, brick walls, etc. The material is dense, it is difficult to absorb and transmit sound energy, and the reflectio...
