Abstract

The invention discloses composite gypsum based thermal insulation mortar prepared from the following raw materials in parts by weight: 40-50 parts of citric acid gypsum, 10-15 parts of boron gypsum, 0.5-1 part of fatty alcohol polyoxyethylene ether sodium sulfate, 1-2 parts of calcium alginate, 0.5-1 part of lactose, 1-3 parts of aluminum oxide, 1-2 parts of calcite powder, 4-8 parts of peat soil, 40-50 parts of expanded glass beads, 0.2-0.5 part of ammonium polyphosphate, 0.5-1 part of potassium hydroxide, 1-2 parts of jute fiber and 4-8 parts of adjuvant. The thermal insulation mortar disclosed by the invention is prepared by effectively utilizing waste industrial gypsum so as to be energy-saving, environment-friendly, green and pollution-free; and the thermal insulation mortar is favorable in thermal insulation performance and durability and good in social and economic benefits.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite gypsum-based thermal insulation mortar and a preparation method thereof. Background technique [0002] Insulation mortar is an important building material used to construct the thermal insulation layer of the building surface, and plays a vital role in the thermal insulation and energy saving effect of the building. With the implementation of the national building energy conservation policy, more and more attention has been paid to the rational use of safe and environmentally friendly materials and sustainable development in the construction industry. [0003] Citric acid gypsum is the waste of citric acid production, and borogypsum is the waste of boric acid production with colemanite. Among them, the annual residue of citrate gypsum in my country reaches 100kt. The discharge of these industrial wastes not only pollutes the environment, but also wastes resources. ...
