A kind of preparation method of energy-saving ceramsite light-weight wallboard

Abstract

The invention relates to the technical field of wallboard production, and particularly discloses a preparation method for an energy-saving ceramsite lightweight wallboard. The method comprises the following steps that S1, a rectangular heat preservation wall core is selected, a plurality of V-shaped through holes are formed in the heat preservation wall core, each through hole comprises two open ends and a connecting end, sodium bicarbonate is placed at the connecting ends, and a plurality of fine grooves are formed in the surface of the heat preservation wall core; S2, a mold is selected, theheat preservation wall core is vertically placed into the mold, one side edge of the heat preservation wall core is enabled to be in contact with the bottom of the mold; S3, net racks are placed on the two sides of the heat preservation wall core correspondingly; S4, a concrete filler with the filling components comprising cement, mixing water, river sand, ceramsite, a water reducer, fly ash, cellulose and an early strength agent is mixed and then is injected into the mold; S5, vibrating is performed on the concrete filler; and S6, demoulding is performed after the concrete filler is solidified and hardened, and the energy-saving ceramsite lightweight wallboard is prepared after demoulding. By adopting the technical scheme, the wallboard can have the relatively high compression resistance.

Description

Technical field [0001] The invention relates to the technical field of wallboard production, in particular to a method for preparing energy-saving ceramsite lightweight wallboard. Background technique [0002] With the further strengthening of national energy conservation and environmental protection and ecological construction policies, green demonstration projects in the construction industry have been continuously promoted, and building wall materials are developing in the direction of energy conservation, soil conservation, waste utilization, environmental protection and improvement of building functions. Traditional partition wall materials consume a lot of non-renewable resources and cause serious pollution problems. At the same time, wet construction makes labor intensity high and construction costs high. Therefore, the partition wall material is gradually upgraded to a lightweight thermal insulation wallboard made of glass fiber reinforced cement or calcium silicate board...

Problems solved by technology

[0003] However, the insulation performance of this light-weight thermal insulation interior wallboard is average. Therefore, a preparation method for lightweight partition wall panels with ceramsite and cement as the main filler material has appeared, and ceramsite is used as coarse aggregate to fill the wall. In the body core material, the insulation wall core is used to cover the inside of the wall; but because the cement will generate heat during the hydration reaction, and the volume will shrink at the same time, it is easy to generate cracks at the insulation wall core, resulting in poor compression resistance of the wallboard
