Abstract

The invention belongs to a foaming insulation board used for building industry, and relates to a foaming insulation board made by industrial waste residue and a manufacturing method thereof. The foaming insulation board comprises the following raw materials by weight ratio: slag powder, desulfurized gypsum, fly ash, quicklime, cement, polypropylene fiber, hydrogen peroxide, water glass, disodium methylene dinaphthalenesulfonate, a water reducer, a waterproof agent and water. The method comprises the following steps: placing the raw materials according to ratio in a mixer for stirring and mixing, casting in a die, and solidifying and performing wet and heat maintenance to obtain the foaming insulation board. The foaming insulation board mainly employs industrial waste residue, and has the advantages of energy saving and environmental protection, good thermal insulation performance, high compressive strength, low production cost and simple process.

Description

technical field [0001] The invention belongs to a foamed thermal insulation board used in the construction industry, and relates to a foamed thermal insulation board made of industrial waste residue and a manufacturing method thereof. Background technique [0002] Extruded boards and foamed boards made of plastic materials such as polystyrene and polyurethane currently used, although light in weight and thermal insulation, have low compressive strength and are flammable, seriously threatening the safety of people's lives and property. Granular rubber powder mortar made of porous lightweight materials such as perlite solves the problem of fire prevention, but it has high water absorption rate, is easy to crack, and has poor thermal insulation effect. Foamed cement insulation board has a good light-weight heat insulation effect, but a large amount of cement is not conducive to energy conservation and environmental protection.
