Abstract

The invention belongs to the technical field of environment protection and energy saving, in particular to ardealite-based heat insulation mortar. The ardealite-based heat insulation mortar is prepared from 12 to 20 parts of cement, 10 to 20 parts of ardealite, 80 to 120 parts of glass beads, 2 to 8 parts of quartz sand, 20 to 30 parts of water, 3 to 6 parts of quicklime and 1 to 2 parts of organic bonding agents in parts by weight. The raw materials use chemical gypsum produced through wet process phosphoric acid production as raw materials; the cost is effectively reduced; the comprehensiveutilization path of the ardealite waste can be widened; the consumption of solid waste in phosphorus chemical industry is increased; the sustainable development of the phosphorus chemical industry canbe promoted.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy saving, in particular to a phosphogypsum-based thermal insulation mortar and a preparation method thereof. Background technique [0002] my country's external wall insulation includes organic insulation systems, inorganic insulation systems, and organic and inorganic composite insulation materials. Among them, organic insulation materials are mainly used. The production and construction technology is very mature, but they cannot be fireproof, pollute the environment, and are easy to age. Inorganic thermal insulation mortar materials have received widespread attention due to their advantages such as low finished product, high strength, thermal insulation, fire prevention, and weather resistance. Vitrified microbead thermal insulation mortar is a new type of inorganic thermal insulation mortar material for external wall insulation, which is made by mixing vitrified micro...
