Problems solved by technology

However, organic thermal insulation materials are combustible and flammable materials that are not resistant to high temperatures and soften at around 100°C. Burning quickly spreads on the combustible body. This kind of fire is difficult to achieve effective rescue and often causes serious economic losses and casualties.

Abstract

The invention relates to a non-grouting-molded inorganic thermal insulation board and a preparation method thereof. The components of the grouted-molded inorganic thermal insulation board are: 500-600 parts of high-alumina cement, 100-200 parts of ordinary silicon cement, desulfurization 100-200 parts of gypsum, 350-450 parts of vitrified microbeads, 3 parts of hydroxypropyl methylcellulose, 1 part of 6mmPP fiber, 8 parts of glass fiber mesh, 4 parts of non-woven fabric, 4 parts of animal protein foaming agent, 1000 parts of water. The grouting-molded inorganic thermal insulation board has high strength, is not easy to pulverize, has low water absorption, strong adhesion to the wall, is not easy to fall off, and has low thermal conductivity, which has a good energy-saving and thermal insulation effect. Therefore, the grouting molding The inorganic thermal insulation board has two functions of fire prevention and energy-saving insulation at the same time, so that the building is safer and more energy-saving, and the building meets the requirements of energy-saving, environmental protection, and green buildings.

Description

technical field [0001] The invention relates to a grouting-molded inorganic thermal insulation board and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] At present, there are many kinds of thermal insulation materials in my country's construction industry, which are mainly divided into organic thermal insulation materials and inorganic thermal insulation materials according to their chemical composition. Organic thermal insulation materials, due to complete sets of equipment, less investment, quick factory construction, light bulk density and low thermal conductivity, are very suitable for building thermal insulation, so they are developing rapidly. It can be said that organic thermal insulation materials have made great contributions to building energy conservation. However, organic thermal insulation materials are combustible and flammable materials, which are not resistant to high temperatures and soften ...
