Abstract

The invention relates to the technical field of building materials, in particular to a phosphogypsum thermal insulation block and a preparation process thereof. The block comprises a block body, the top of the block body is provided with a decorative panel, and the decorative panel is matched with the top surface size of the block body. One side of the block body is provided with a connection slot, and a side, away from the connection slot, of the block body is provided with a connection protrusion, and the block body comprises the following raw materials in percentage: 40%-70% of building phosphogypsum, 20%-30%of fly ash, 10%-20% of cement, 2%-3% of gas generator, 0.75%-1.5% of retarder, 0.75%-1.5% of water reducing agent and 1 .5%-3% of chopped fiber. The invention adopts the building phosphogypsum as a cementing material, the phosphogypsum thermal insulation block has higher strength, and excellent mechanical properties, light weight and heat preservation properties, the thermal conductivity is 0.25-0.3 W/m.k, the compressive strength can reach 3.5-4.5MPa, the thermal insulation capacity is high, the weight is light and the seismic performance is good. The 120 mm thick phosphogypsum thermal insulation block has a weight of less than 90kg/m<2>. The gas generator makes the phosphogypsum thermal insulation block contain a large number of small holes and has heat preservation and insulation performance, and the added chopped fiber can effectively suppress crack problems.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a phosphogypsum thermal insulation block and a preparation process thereof. Background technique [0002] Phosphogypsum block is a sustainable green building material product, and it is necessary to speed up the research on the application technology of phosphogypsum wall materials and broaden its application forms. Phosphogypsum walls have not been widely used since they were introduced into China in the 1980s like other cement wall materials. There is a large amount of phosphogypsum waste that is not easy to handle every year, and it is necessary to turn waste into treasure as soon as possible. With the advancement of wall reform in China, a development space has been created for new types of walls that use phosphogypsum as raw materials. [0003] At present, China has begun to use architectural phosphogypsum to produce building materials and apply them to projects;...
