Modified magnesium cement light wallboard
The invention provides a modified magnesium cement light wallboard. The modified magnesium cement light wallboard is composed of a foaming agent and the following components in parts by weight: 100 parts of magnesium oxide, 5-40 parts of fly ash and/or expanded perlite and polystyrene foam plastic light fillers, 60-80 parts of a sulfur-magnesium-phosphorus blending solution with the baume degree of 20-28 degrees, wherein the sulfur-magnesium-phosphorus blending solution is composed of the following components in parts by weight: 1 part of 50% sulfuric acid, 0.5 part of magnesium sulfate heptahydrate and 0.001 part of 50% phosphoric acid; and the volume ratio of the air bubble volume of the foaming agent to the total volume of the components is (4-5.8) to 1. According to the modified magnesium cement light wallboard, the sulfur-magnesium-phosphorus blending solution is used for replacing a magnesium chloride solution in the prior art, and magnesium chloride with strong activity and poor stability is removed; the technical problem that the quality of a magnesium cement wallboard is difficult to control is basically improved; and the defects, which are difficult to solve for a long period, that the magnesium cement wallboard has efflorscence halogenation and warping deformation, and corrodes a metal components, caused by chloridions are overcome.
