Abstract

The invention provides a magnesium oxychloride fiber light wallboard, and relates to the wallboard field in the construction materials. The wallboard is composed of the following components in parts by weight: 40 to 60 parts of magnesium chloride water solution, 20 to 30 parts of magnesium oxide, 0.1 part of fly ash, 0.2 part of slag, 0.5 part of construction waste, 0.1 part of waste ceramic, 2 parts of short glass fiber, 2 parts of straw, 2 parts of saw dust, 3 parts of perlite, and 0 to 2 parts of modifier. The formula of the wallboard comprises industrial and agricultural wastes such as fly ash, slag, mineral slag, construction wastes, broken ceramics, straws, and saw dust, thus the wastes are fully recycled and reutilized, and moreover the using amount of sands and stones is reduced, so the destroy on mountain and river bed is avoided, resources are saved, and environment is protected. The prepared magnesium oxychloride fiber light wallboard has the advantages of good water resisting property, high compressive strength, good freeze resisting performance, good acid / alkali resistant property, no halogen appearance, no scumming, and no deformation.

Description

technical field [0001] The invention relates to a wallboard, in particular to a lightweight magnesium oxychloride fiber wallboard and a preparation method thereof. Background technique [0002] At present, wall panels are generally made of bricks, which not only has a long construction period, is time-consuming and labor-intensive, and has low construction efficiency, but also consumes a large amount of concrete. Destroying natural mountains; digging riverbeds to take sand also caused water and soil erosion, and there was a serious crisis in concrete raw material resources. In many areas of our country, there has been a serious shortage of sand and gravel aggregate resources. [0003] Lightweight wallboard is a new type of energy-saving wall material. It is more and more widely used in various frame structures such as prefabricated houses or offices, hotels, and residential quarters due to its light weight, easy use, and fast construction. Inner partition wall. The curre...
