Abstract

The invention discloses a high-strength light-weight non-combustible modified foam thermal insulation material of cement-based waterborne polyester resin. The foam thermal insulation material comprises the following components in percentage by weight: 6.0%-7.5% of waterborne polyester resin, 45%-57% of cement, 20%-25% of water, 1%-2.5% of oleic acid, 1%-8% of inorganic packing, 10% of a foaming agent, 1%-2% of a curing agent, 0.5% of a catalyst, 0.5% of a coagulation agent, 0.5% of a foam stabilizer and 0.5% of a glass fiber. The invention also discloses a preparation method of the modified foam thermal insulation material of the cement-based waterborne polyester resin and application of the modified foam thermal insulation material. The modified foam thermal insulation material has the innovation points that four problems of light weight, high strength, heat preservation and non-inflammability are simultaneously solved; the application is innovated; secondary construction of sticking the thermal insulation material on an outer wall or an inner wall in the past is replaced; a thermal insulation wall body is directly fabricated; and the foam thermal insulation material is applied to building partition walls, bearing wall bodies or outer wall thermal insulation structures, and molding processing of artistic relief and model sculpture.

Description

technical field [0001] The invention belongs to the field of thermal insulation building materials, and in particular relates to a high-strength light-weight non-combustible cement-based water-based polyester resin modified foam thermal insulation material, a preparation method and an application thereof. Background technique [0002] At present, the commonly used building insulation materials at home and abroad are mainly organic foam materials and inorganic foam materials. Organic types such as: polystyrene foam (EPS, XPS), rigid polyurethane foam insulation materials, phenolic resin insulation materials. Inorganic insulation materials such as foam glass, rock wool board, foam concrete (foam mortar), expanded perlite insulation mortar, fiber cement insulation board, etc., all have their own characteristics. [0003] The advantages of organic thermal insulation foam materials are light weight, good thermal insulation performance (small thermal conductivity), but the streng...
