Abstract

The invention discloses a preparation method for a high-toughness aging-resistant wall insulation material, belonging to the technical field of building materials. Quartz sand and moissanite contain alarge amount of silicon carbide; silicon carbide reacts with oxygen to produce silica and carbon dioxide; carbon dioxide foams and reduces the heat conduction efficiency of the material; lycopene hasstrong antioxidant capacity and strong aging resistance; the surface of an agitated substance contains a large amount of active groups, and the active groups act with active groups on a wall surface,so the wall insulation material prepared in the invention is improved in adhesion to a wall substrate; after the powder of Pinus nigra var is soaked in an alkali solution, lignin is decomposed, cellulose and hemicellulose are partially decomposed; the fiber of Pinus nigra var has high ultraviolet resistance and is resistant to aging, the undecomposed cellulose of Pinus nigra var improves the aging resistance of the wall insulation material; and the wall insulation material has good application prospects.

Description

technical field [0001] The invention discloses a preparation method of a high-toughness and aging-resistant wall thermal insulation material, which belongs to the technical field of building materials. Background technique [0002] Wall insulation material is a material that can have heat insulation function inside or outside the wall. There are many insulation material products, most of which are external wall insulation. The insulation layer is completed at the same time as the building, and there are also internal insulation. , the stairs of general buildings are internal insulation. [0003] Wall energy-saving and thermal insulation materials include organic (such as benzene board, polystyrene board, extruded board, polystyrene foam board, rigid polyurethane foam, polycarbonate and phenolic, etc.), inorganic (such as perlite cement board, foam Cement board, composite silicate, rock wool, autoclaved sand aerated concrete block, traditional thermal insulation mortar, etc....
