Magnesia composite material for roofs and preparation process of magnesium composite

Abstract

The invention relates to a magnesia composite material for roofs. The magnesia composite material comprises the following raw materials in percentage by weight: 30%-70% of a base material, 20%-60% of filler and 10%-15% of an auxiliary material, wherein the base material is a mixture of magnesium oxide and magnesium chloride, the filler is lightweight filler or inert filler, and the auxiliary material is a reinforcing material. The magnesia composite material has the advantages of compact solidification body, high strength, high cementitious property, high durability, good workability, good fireproof property, good salinity and alkalinity resistance and the like; besides, the magnesia composite material is quick to solidify and easy to cure, is energy-saving and environment-friendly, belongs to a green, environment-friendly and energy-saving product, and has wide applications in multiple fields such as building materials and the like.

Description

technical field [0001] The invention relates to a magnesium composite material and a preparation process thereof, in particular to a magnesium composite material for roofing and a preparation process thereof, belonging to the technical field of building materials. Background technique [0002] Although magnesium cement products have gone beyond the original scope of magnesium cement products as wood-saving materials, their applications are mostly limited to plate products, decorative products and other fields. It is the development trend of the magnesium cement industry to jump out of the framework of traditional magnesium cement products and transform to an industrial system with new building materials as the main body. Qinghai Qaidam Circular Economy Pilot Zone has gradually developed into an important national inorganic chemical raw material and production base. With the acceleration of the development process, it has increasingly shown its special geographical and resour...

Problems solved by technology

However, in practical applications, when used as building materials, magnesia cementitious materials also expose some shortcomings, especially the magnesium oxychloride cement without any modifiers, which has poor water properties, expansion deformation, moisture absorption, halogen return, and frosting. The problem of corroded rebar
