Abstract
The invention relates to the technical field of building materials, in particular to an air-hardening fast felt. The air-hardening fast felt product is prepared by impregnating a cementitious material into an engineering felt and then sealing the engineering felt with a sealing plastic film, wherein the cementitious material is composed of the following raw materials in parts by weight: 20 to 30 parts of a base material, 3 to 6 parts of a functional filler, 3 to 5 parts of a synergistic aid, 2 to 4 parts of a composite hardening accelerator and 2 to 4 parts of a compound nano powder. The cementitious material is prepared by placing the base material, the functional filler, the synergistic aid, the composite hardening accelerator and the compound nano powder in a mixing device for mixing. The prepared air-hardening fast felt has not only good mechanical properties, but also excellent weather resistance, and is suitable for use in water-free places, thereby effectively ensuring its quality.
