Abstract

The invention provides an inorganic foamed concrete insulation board and a preparation method thereof. The insulation board comprises foamed concrete, and has density of 160-250kg / m<3>, compressive strength of 0.3-0.5 MPa, and coefficient of thermal conductivity of 0.05-0.062 W / m.K. The prepared insulation board has the characteristics of low unit weight and good heat insulation effect, and can be widely used as an insulation material in the field of construction.

Description

technical field [0001] The invention relates to a thermal insulation material and a preparation method thereof, in particular to an inorganic foamed concrete thermal insulation board and a preparation method thereof. Background technique [0002] Foamed concrete, also known as foamed concrete, is to introduce nitrogen, carbon dioxide, oxygen or air into the concrete slurry by chemical or physical means according to the application requirements, and after molding and reasonable maintenance, the formation contains a large number of holes and has a certain strength. concrete products. Foam concrete can be divided into cement foam concrete, magnesite foam concrete, gypsum foam concrete and pozzolanic cement foam concrete according to the composition of cementing materials; according to the type of main filler used, it can be divided into fly ash foam concrete and slag foam concrete , Straw foam concrete; according to density, it can generally be divided into six grades, namely ...
