Problems solved by technology
The use of organic insulation systems in building maintenance structures can achieve building energy conservation, but there are deficiencies in their application to building maintenance structures: organic insulation materials are prone to aging under natural conditions, and their service life is limited when used in building maintenance structures; organic insulation materials It is flammable, and it is difficult to meet the "non-combustible or flame-retardant requirements" of building maintenance structures for thermal insulation materials
Inorganic thermal insulation materials represented by foamed concrete have good chemical stability, long service life, non-combustibility, and can meet fire protection requirements under various conditions, but their thermal conductivity is relatively large, so they are used in building maintenance structures to improve thermal resistance limited

Abstract
The invention discloses a heat-insulating and energy-saving board of an ecological building prepared from volcanic ash and a preparation method thereof. The energy-saving board comprises frameworks and pore spaces among the frameworks, wherein the frameworks comprise the following components in parts by weight: 10-95 parts of volcanic ash and 5-90 parts of inorganic gelled material; and the pore spaces are closed pore spaces with the size of 0.1-5mm and the porosity of 20-80 percent. The heat-insulating and energy-saving board has the advantages of long service life, low preparation cost, small heat conductivity coefficient and favorable heat-insulating performance.
Description
technical field [0001] The invention relates to a thermal insulation and energy-saving board and a preparation method thereof. Background technique [0002] In order to achieve building energy saving, one of the feasible methods is to increase the thermal resistance of the building maintenance structure. The common method is to use insulation materials on the building maintenance structure: it has a small thermal conductivity, good chemical stability, certain mechanical strength, and a long service life. Compatible with the normal maintenance period of the main body of the building, it is non-combustible or flammable, and has good constructability. [0003] Existing insulation materials are often porous materials, such as organic insulation systems represented by polystyrene board insulation materials and polyurethane insulation materials, and inorganic insulation systems represented by foamed concrete. The thermal conductivity of organic thermal insulation materials is low...
