Non-load bearing building energy-saving wallboard and preparation method thereof

Abstract

The invention discloses a non-load bearing building energy-saving wallboard and a preparation method thereof. The wallboard is prepared by adopting a prefabricating method, and comprises a decorative layer, a protective layer, a heat insulation layer and a concrete structural layer, wherein the decorative layer is positioned on the outer surface of the wallboard; the protective layer is positioned at the inner side of the decorative layer, and consists of polymer modified cement mortar and alkali-resistant fiberglass mesh; the heat insulation layer is positioned at the inner side of the protective layer, and consists of inorganic heat insulation mortar or an inorganic heat insulation board with compressive strength of over 1.0MPa; and the concrete structural layer is positioned at the inner side of the heat insulation layer and positioned at the outer side of a building foundation structure. The prefabricated wallboard is combined with a building envelope wallboard through a lightweight external wall heat insulation decorating system, so that good heat insulation and decoration properties can be provided on the premise of ensuring the safety performance of the system, the difficulty of building construction using the wallboard is effectively reduced, and energy is reduced.

Description

technical field [0001] The invention relates to building enclosure structures in the technical field of building energy conservation, in particular to a non-load-bearing building energy-saving wall panel and a preparation method thereof. Background technique [0002] At present, the total energy consumption of buildings in my country has exceeded 30% of the total primary energy consumption, ranking first in energy consumption, and the proportion of building energy consumption in my country's energy consumption is still increasing year by year. Building energy conservation has become one of the key areas of energy conservation in the whole society First, the energy-saving and thermal insulation of building exterior walls is one of the key points of building energy-saving and consumption-reducing. There are mainly three energy-saving methods of the existing building envelope structure, three methods of external wall internal insulation, external wall internal insulation and san...

Problems solved by technology

These three insulation methods have their own advantages and disadvantages. The advantage of external wall insulation is that it can effectively avoid the generation of cold and heat bridges and effectively protect the main structure. However, the disadvantage is that the widely used organic insulation boards have relatively poor fire resistance. , and its construction is relatively difficult; the advantage of internal insulation of the external wall is that the construction is relatively simple and the cost is low, but its disadvantages are also obvious. It is difficult to avoid the generation of cold and thermal bridges by adopting the method of internal thermal insulation of the external wall. The junction of layers is prone to condensation, mildew, etc.; the advantage of sandwich insulation is that it has lower requirements for insulation materials, especially the strength of insulation materials. The disadvantage is that the generation of cold and heat bridges cannot be avoided, and construction is difficult.
