Modified foam thermal insulation material based on waterborne polyester resin and preparation method of modified foam thermal insulation material

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.
