Abstract

The invention provides a humidity-regulating phosphogypsum wall material suitable for a fabricated building and a preparation method of the humidity-regulating phosphogypsum wall material. The humidity-regulating phosphogypsum wall material comprises the following raw material components: in parts by weight, 100 parts of phosphorus building gypsum, 0.3-0.5 part of a water reducing agent, 0.05-0.15part of an air entraining agent, 5-15 parts of modified composite diatomaceous earth and 0.05-0.15 part of a retarder, and vitrified microbeads are added at an amount of 10-20% of the volume of the phosphorus building gypsum. The industrial waste phosphogypsum is adopted as a main raw material, the humidity-regulating phosphogypsum wall material with rapid forming curing and a humidity-regulatingfunction is obtained through introduction of lightweight components, humidity-regulating components and other functional components, and can be applied to inner walls of fabricated buildings, so thatthe way of resource utilization of phosphogypsum solid waste is enriched; and the humidity-regulating phosphogypsum wall material can be widely applied to fabricated civil buildings.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a phosphogypsum wall material with a humidity-regulating function suitable for prefabricated buildings and a preparation method thereof. Background technique [0002] With the development of social economy and science and technology, people gradually pay attention to the development and application of new building materials. Compared with traditional building materials, building energy-saving and environmentally friendly materials have the characteristics of low cost, low pollution, and high recycling rate, which conforms to the concept of modern environmental protection and is conducive to promoting the sustainable and healthy development of society. The prefabricated building is a building that is prefabricated by the factory and connected on site. It has the advantages of energy saving, environmental protection, and fast construction. It is the current development dir...
