Abstract

The invention relates to the field of wallboard preparation processes, in particular to a light sound insulation wallboard and a preparation method thereof. The light sound insulation wallboard is prepared from the following components in parts by weight: 34.2-51 parts of water, 85 to 95 parts of ceramsite, 30 to 40 parts of river sand, 25 to 30 parts of pottery sand, 20 to 35 parts of fly ash, 90to 100 parts of low-alkalinity sulphoaluminate cement, 15 to 25 parts of medical stone powder; 3-5 parts of a water reducing agent, and 5-13 parts of a fiber mixture. The light sound insulation wallboard and the preparation method thereof have the beneficial effects that the mixture D is obtained through specific components in parts by weight, then the mixture D is paved through a wallboard machine, the wallboard is prepared through the steps of standing, cutting, maintaining and the like, and the prepared wallboard has the advantages of being light in weight and good in sound insulation effects.

Description

technical field [0001] The invention relates to the technical field of wallboard preparation technology, more specifically, it relates to a light-weight soundproof wallboard and a preparation method thereof. Background technique [0002] Lightweight wallboard is a new type of energy-saving wall material composed of various industrial waste residues such as cement and fly ash. It has the advantages of light weight, high strength, multiple environmental protection, sound insulation, and rapid construction.
