The invention discloses a toughened crack-resistant high-flexibility thin spraying material as well as a preparation method and application thereof, and belongs to the technical field of surface sealing, reinforcing and supporting of mine laneway
engineering. The toughened crack-resistant high-flexibility thin spraying material is prepared from the following components in parts by
mass: 100 parts of a cementing material, 170 to 200 parts of
styrene-butadiene
emulsion, 40 parts of water, 2 to 15 parts of
basalt fiber, 5 to 30 parts of rubber
powder, 0.1 to 2 parts of a drier, 0.1 to 2 parts of an accelerator, 0.8 to 5 parts of a curing agent, 1 to 3 parts of a cross-linking agent, 1 to 5 parts of a
foaming agent, 0.2 to 1 part of a penetrant, 2.5 to 3 parts of a
flame retardant and 3 to 5 parts of a rheological additive. Compared with sprayed concrete, the prepared thin spraying material is thin in spraying layer, high in construction efficiency, low in
material consumption, free of dust and low in
pollution, and has high flexibility, tensile strength and adhesion performance.
