Building waterproof thermal-insulation mortar and preparation method thereof

Abstract

A building waterproof thermal-insulation mortar is characterized by being prepared from the following raw materials in parts by weight: 300-400 parts of cement, 40-50 parts of waste building brick powder, 20-24 parts of wood fiber, 4-6 parts of calcium formate, 7-9 parts of hydroxypropyl methyl cellulose, 40-45 parts of silicon carbide micro powder, 10-20 parts of calcium oxide powder, 10-12 parts of brown fused alumina powder, 30-35 parts of dry city sludge powder, 40-45 parts of Datong earth, 4-6 parts of aluminum sulfate, 20-24 parts of carboxymethyl starch, 4-6 parts of modified nano carbon powder and 600-650 parts of water. The building waterproof thermal-insulation mortar has a good thermal-insulation property, can be cemented to a wall firmly, and has excellent compressive and tensile properties, as well as good weather-resistant, environmental-friendly, waterproof, anti-cracking and anti-flaking properties.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a building waterproof and 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 construction, the u...

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
