Abstract

The invention belongs to the field of buildings, and particularly discloses an energy-saving and environment-friendly light wallboard and a preparation method thereof. The light wallboard is preparedfrom the following components by weight: 10-28 parts of Portland cement, 10-25 parts of coarse aggregate, 20-40 parts of fine aggregate, 4-9 parts of silica fume, 3-5 parts of fiber, 2-7 parts of expanded perlite, 2-5 parts of water-based nano carbon black, 3-12 parts of slag powder, 4-6 parts of nano calcium carbonate, 70-120 parts of water and 2- 6 parts of an additive. The production cost is reduced, the wallboard molding strength is high, and compared with a traditional light wallboard, the light wallboard still has high strength and high waterproof performance in the long-term use process, a large amount of industrial waste residues are utilized as the raw materials, waste is turned into wealth, the purposes of saving energy and protecting the environment are achieved, and the compression resistance and the waterproof performance of the wallboard are improved.

Description

technical field [0001] The invention relates to related fields of construction, in particular to an energy-saving and environment-friendly lightweight wallboard and a preparation method thereof. Background technique [0002] Wallboard is a commonly used construction material in the process of house decoration. The function of wallboard is mainly used in exterior wall insulation wall construction, interior wall partition board, etc. In addition to the functions of sound insulation and fire prevention, the partition board should also have low energy consumption. Energy saving, heat insulation, impermeability, freeze-thaw resistance, anti-carbonization and other functions, and meet the requirements of aesthetics of architectural art decoration. With the continuous development of urban buildings, in order to save space and reduce loads, non-load-bearing walls in various construction projects generally use lightweight wall panels. At present, there are many types of lightweight ...
