Composite light wall board and production method thereof

Abstract

The invention provides a composite light wall board and a production method thereof, and belongs to the technical field of production of building wall materials. The composite light wallboard is of a three-layer composite structure consisting of a lower compact face layer, a light sandwiched layer and an upper compact face layer in a seamless compositing manner, wherein the thickness of the lower compact face layer is equal to that of the upper compact face layer, and the thickness of the light sandwiched layer ranges from 40mm to 140mm. Besides, the lower compact face layer and the upper compact layer are formed by the same manner of compositing mortar with a layer of alkali-resistant glass fiber mesh fabric, and the light sandwiched layer is formed by compositing hollow ceramic-particle light aggregate concrete with reinforced rib meshes. The composite light wall board has the advantages of high strength, low face density, convenience in construction, good heat and sound insulation effect and the like.

Problems solved by technology

[0002] Most of the inner partition wall materials in the prior art are solid or hollow clay bricks. The processing and use of this traditional wall material takes up waste land, consumes a lot of energy, and is wet-work construction, which makes construction management difficult. The construction environment is harsh, and the bigger disadvantage is that due to its heavy weight, the use of other supporting materials in the building structure increases, such as the increase in the use of masonry mortar, resulting in unnecessary waste

In addition, these traditional materials do not have the effect of heat preservation and sound insulation, so it is imperative to improve the traditional wall materials. The substitutes that have appeared so far include plates with perlite concrete structures, plates with ceramsite concrete structures, and gypsum hollow walls. Slats, ceramsite foam concrete slats, GRC sandwich light concrete composite wall panels, etc.

These wall panels are either hollow slabs made of ceramsite light aggregates and cement with high strength but large bulk density as the main raw materials, or polystyrene particles or expanded perlite ultra-light aggregates and cement, etc. Lightweight composite wallboards are made of the main raw materials. The mechanical parameters of these wallboards are currently unsatisfactory, or the strength is low, or the surface density is high, or the heat insulation and sound insulation properties are not ideal, so they cannot be widely used. Ground applications, especially gypsum slats, cannot be used in environments that are in contact with water, otherwise their mechanical properties will be significantly reduced

In addition, the current performance of these wall panels can only meet the technical index requirements for partition wall panels that do not require high mechanical performance indicators. If they are further used in household walls and enclosure walls for residential industrialization, their comprehensive use Performance indicators are difficult to meet the needs of these walls
