Abstract

The invention discloses a self-heat-insulation light weight wallboard containing hollow ceramsites and a preparation method thereof, and belongs to the technical field of building materials. The self-heat-insulation light weight wallboard comprises the following components by mass: 20-60 parts of a cementitious material, 5-30 parts of a lightweight aggregate, 0.05-0.5 part of a composite early strength agent, 2-8 parts of a foaming agent, 0.02-0.14 part of a foam stabilizing agent, 0.1-0.8 part of a catalyst, 0.05-0.6 part of a binder, 0.05-0.6 part of straw fiber and 15-30 parts of water. The preparation method is as follows: putting the cementitious materials, the straw fiber and the binder together, then mixing, then orderly adding the water, the foaming agent, the stabilizer and the catalyst, stirring to obtain a slurry mixture, adding hollow ceramsites, obturator perlite and expanded vermiculite in saturated surface-dry condition, stirring, then using an injection pump to inject into a wallboard forming machine for molding, and 3-5 hours after the concrete is solidified and hardened, demoulding to obtain the self-heat-insulation light weight wallboard containing the hollow ceramsites. The self-heat-insulation light weight wallboard containing the hollow ceramsites has energy saving, environmentally-friendly, fire insulating, sound-insulation, high-strength, lightweight, waterproof, thermal-insulation, corrosion-resistant, durable and other characteristics.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a self-insulating lightweight wallboard containing hollow ceramsite and a preparation method thereof. Background technique [0002] The factory prefabrication and assembly construction of residential components is an important symbol of the modernization of the housing industry. Due to the neat size of the lightweight wall panels, easy molding and mechanized production, the production efficiency is high, and the lightweight partition wall panels are large in size, large in size, It has good integrity, can be assembled and installed, and has high construction efficiency. At present, light wall panels are regarded as the preferred interior wall products for residential industrialization at home and abroad, and are widely used in construction projects. [0003] At present, light-weight wall panels mostly adopt the method of sandwiching a layer of polystyrene p...
