Method for preparing inorganic heat preservation insulating board

Abstract

The present invention belongs to the building energy-saving material field, in particular to relate to an inorganic heat-preservation and heat insulation plate and the corresponding preparation method; the inorganic heat-preservation and heat insulation plate consists of cement material; the components and the weight ratio in the preparation process are that: 40-55 percent of cement, 1-15 percent of powder coal ash, 0-15 percent of mine powder, 2-3 percent of tackiness agent, .2-0.3 percent of reinforcing fibre, 0.2-0.4 percent of surface active agent, 2-4 percent of thickening agent, 2-4 percent of foam agent and 35-45 percent of water. The inorganic heat-preservation and heat insulation plate is milled and matched with the materials and is milled according to the stated order. The present invention has the advantages of low cost, much better mechanical character, low heat-conductivity coefficient, not easy to be ignited and to be aged as well as convenient to be manufactured and produced in large scale.

Description

technical field [0001] The invention belongs to the field of building energy-saving materials, and in particular relates to a preparation method of an inorganic thermal insulation board. Background technique [0002] In recent years, with the development of the economy, my country has gradually increased its emphasis on the field of building energy conservation. At present, most of the building thermal insulation materials produced and applied in my country are organic materials, such as polystyrene boards. Although polystyrene boards have good thermal insulation effects in use as thermal insulation materials, the construction process is complicated and the overall cost is high; At the same time, because the hydrophobicity of polystyrene board is not compatible with conventional hydrophilic materials, it is difficult to guarantee the quality of subsequent construction other than the surface layer, and it is prone to quality problems such as cracking, falling off, and hollowin...

Problems solved by technology

At present, most of the building thermal insulation materials produced and applied in my country are organic materials, such as polystyrene boards. Although polystyrene boards have good thermal insulation effects in use as thermal insulation materials, the construction process is complicated and the overall cost is high; At the same time, because the hydrophobicity of polystyrene board is not compatible with conventional hydrophilic materials, it is difficult to guarantee the quality of subsequent construction other than the surface layer, and it is prone to quality problems such as cracking, falling off, and hollowing of the surface layer mortar. Decoration such as facing tiles, use of paint or construction poses a significant constraint

Other organic materials, such as polystyrene particle insulation mortar, foamed polyurethane board, foamed polyethylene, foamed polypropylene, etc., have the common disadvantages of being flammable and aging
