[0045] Embodiment 2: The amount of each material contained in the inorganic thermal insulation dry powder mortar: 700kg of desulfurized gypsum, 40kg of cement; 75kg of fly ash; 110kg of expanded perlite; 55kg of vitrified microbeads; 13kg of redispersible latex powder; Cellulose 3.0kg; polypropylene 1.5kg; starch ether 1kg; composite retarder 1.5kg.

Embodiment 3

[0046] Embodiment 3: The amount of each material contained in the inorganic thermal insulation dry powder mortar: 800 kg of desulfurized gypsum, 30 kg of cement; 15 kg of fly ash; 90 kg of expanded perlite; 30 kg of vitrified microspheres; 25 kg of redispersible latex powder; Base cellulose 4.0kg; polypropylene 1.5kg; starch ether 2kg; composite retarder 2.5kg.

[0047] Dry powder mortar is a single-component dry powder material produced in a factory. It can be used only by adding water and stirring at the construction site. Its advantage is that it overcomes the disadvantages of inaccurate proportioning of two-component materials on site and difficult quality control, and has the advantages of stable and reliable quality and simple and easy construction.

[0048] Inorganic thermal insulation dry powder mortar is mainly used in hot summer and cold winter and hot summer and warm winter regions, which can save energy by 50% and 65% in newly built, rebuilt and expanded civil buil...

Abstract

The invention relates to inorganic heat-insulating dry powder mortar, which comprises the following components in percentage by weight: 30 to 95 percent of inorganic gelled material, 5 to 70 percent of lightweight aggregate and 0 to 10 percent of additive, wherein the inorganic gelled material comprises 75 to 90 weight percent of desulfuration gypsum and 10 to 25 weight percent of cement; the lightweight aggregate is hydrophobic expanded perlite or vitrified micro bubbles or a mixture of the hydrophobic expanded perlite and the vitrified micro bubbles; and the additive comprises a composite retarder, a water retention agent, a thickening agent, a cementing compound and a reinforcing agent. The inorganic heat-insulating dry powder mortar can replace cement mortar and mixed mortar, is applied to non-humid wall surfaces such as the inner side of an outer wall, a separating wall, an inner partition wall, a ceiling and the like, has the characteristics of heat preservation, heat insulation, crack resistance, fire prevention, ageing resistance, environmental protection, biological bite corrosion prevention and the like, and can improve the heat-preserving and heat-insulating performanceof wall bodies.

Description

technical field [0001] The invention relates to a building material, in particular to an inorganic thermal insulation dry powder mortar used for interior wall plastering. Background technique [0002] Energy is the basic condition for the survival and development of human beings, and saving energy is the basic national policy of our country. Building energy consumption has accounted for 30% of the total social energy consumption in our country. Therefore, improving energy efficiency in the process of building use is of great significance to my country's energy conservation and emission reduction work! [0003] Energy-saving materials for walls of building enclosure structures can be divided into organic materials, such as polystyrene board, rubber powder particles, polyurethane, etc., and inorganic materials, such as aerated concrete, vitrified microbeads, rock wool, etc. Two categories. [0004] The current wall energy-saving products in my country are mainly based on org...
