High-strength iron-ore slag-containing powder thermal insulation mortar and preparation method thereof

Abstract

High-strength iron-ore slag-containing powder thermal insulation mortar is characterized by comprising the following raw materials in parts by weight: 300 to 340 parts of cement, 50 to 55 parts of cement road slag powder, 20 to 24 parts of iron-ore slag powder, 8 to 10 parts of flaky graphite, 14 to 18 parts of sodium bentonite powder, 5 to 8 parts of sodium carboxymethyl cellulose, 20 to 25 parts of meerschaum powder, 50 to 56 parts of kaolinite powder, 10 to 15 parts of gypsum powder, 4 to 6 parts of hydroxypropyl sesbania gum powder, 5 to 8 parts of xanthan gum, 1 to 2 parts of acrylamide, 3 to 4 parts of borax, 4 to 6 parts of modified nano-carbon powder, and 600 to 650 parts of water. The thermal insulation mortar adopting iron-ore slag powder is high in unit weight, low in heat conductivity, anti-crack, ageing resistant, high in cohesive force, good in workability and construction property, convenient to use, waterproof, impervious, high in compressive strength, convenient to store and transport, and pollution-free.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high-strength iron ore slag powder 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 attracted extensive attention due to their advantages such as low finished product, high strength, thermal insulation, fire prevention, and weather resistance. However, there are still disadvantages such as high cost and limited material sources, and there is still room for improvement. [0003] With the development of building green construc...

Problems solved by technology

Among them, organic insulation materials are mainly used. The production and construction technologies are very mature, but they cannot prevent fire, pollute the environment, and are easy to age.

Inorganic thermal insulation mortar materials have received extensive attention due to their advantages such as low finished product, high strength, thermal insulation, fire resistance, and weather resistance, but there are still disadvantages such as high cost and limited material sources, and there is still room for improvement.

[0003] With the development of building green construction, the use of abandoned concrete blocks, standard bricks and (hollow) aerated concrete blocks and other construction solid wastes has become a commonly used material for energy saving requirements, but due to its large size and relative strength Therefore, during the handling process, it is easy to cause damage to the edges and corners due to improper operation, and this part of the blocks will not be used for the main project
