Abstract

The invention relates to a microbubble magnesia cement internal / external wallboard and a preparation method thereof. The invention belongs to the technical field of light boards. The microbubble magnesia cement internal / external wallboard comprises the following components in parts by weight: 100 parts of magnesia, 16-50 parts of magnesium chloride, 2-45 parts of microbubble foaming agent, 26-75 parts of water, 1-16 parts of glass fiber cloth, 0.1-0.3 part of non-woven fabric and 0.2-4 parts of magnesite modifier. The preparation method comprises the following steps: (1) mixing magnesium chloride and water, and adding magnesia; (2) adding fly ash, sawdust, reclaimed materials and perlite; (3) adding magnesite modifier; (4) adding microbubble foaming agent; (5) putting into a mold to form a bottom layer, laying the glass fiber cloth layer on the bottom layer, adding slurry to form a plurality of separation layers (the glass fiber cloth layer is laid between every two separation layers, and the topmost slurry forms the surface layer), and finally, extruding with pressure rollers to obtain a blank board; and (6) curing the blank board, sanding and cutting to obtain the finished product. By adding the microbubbles, the invention has the advantages of simple method, good product quality, small volume, low cost and the like, and is convenient to process.

Description

technical field [0001] The invention belongs to the technical field of lightweight boards for construction, in particular to an inner and outer wall board with microfoam glass magnesium cement and a preparation method thereof. Background technique [0002] At present, with the wide application of glass magnesium cement board and glass magnesium products in the construction industry, the glass magnesium industry is booming, resulting in a sharp shortage of raw material supply. A certain proportion of fly ash, sawdust, straw powder, rice husk powder, perlite and other materials are used as filling materials in the manufacture of glass magnesium board. Fly ash, sawdust, straw powder, rice husk powder, etc. are industrial and agricultural wastes that are discarded. Even so, waste materials are now readily available, and the price and cost are increasingly used in the product market, resulting in product quality, volume, and production. cost and other technical issues.
