Aerated phosphorus building gypsum heat preservation block and preparation method thereof

Abstract

The invention discloses an aerated phosphorus building gypsum heat preservation block and a preparation method thereof. The aerated phosphorus building gypsum heat preservation block is prepared fromthe following raw materials by mass percent: 71-82% of phosphorus building gypsum, 4-6% of calcium carbonate, 7.5-10% of aluminum sulfate, 2-3% of a foam stabilizer, 0.75-1.5% of a retarder, 0.75-1.5%of a water reducing agent and 1.5-3% of chopped fiber. The aerated phosphorus building gypsum heat preservation block prepared by the invention is excellent in the aspects of mechanical property andlight-weight heat preservation, accumulated industrial byproduct gypsum is utilized to produce the aerated phosphorus building gypsum heat preservation block, a block body material, which is good in heat preservation effect and light in self-weight and has good compression resistance and crack resistance, is produced when the utilization of solid waste and environmental protection are simultaneously solved, the material has a positive meaning in the aspects of resource saving and environmental protection, a large quantity of phosphorus building gypsum can be utilized for the material, and thematerial can be recycled, thereby being more environmentally friendly.

Description

technical field [0001] The invention relates to an aerated phosphorus building gypsum thermal insulation block and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] In China, the production of industrial by-product gypsum is large and pollutes the environment seriously (such as phosphogypsum), so it needs to be developed and utilized. At present, China has begun to use phosphogypsum to produce building materials and apply them to projects; the wall masonry materials in the construction industry mainly use clay bricks, solid blocks or hollow blocks. These materials have a single variety, poor thermal insulation performance, and waste Resources also affect the performance of the house. [0003] Ordinary clay bricks are small and heavy; aerated concrete blocks are large and heavy; hollow blocks are large and light, but the recycling of demolition waste is poor, the thermal conductivity is large, and the cost is ...
