Abstract
The invention discloses a guniting material and a preparation method thereof.The guniting material comprises a component A and a component B. The component A comprises a microcapsule high polymer material, a coalescing agent, a plasticizer, a waterproof agent, a weather-proof agent, carbonate, silicate and silica fume which are optimized in proportion, and the dosage of each component is equal to that of the microcapsule high polymer material, the coalescing agent, the plasticizer, the waterproof agent, the weather-proof agent, the carbonate, the silicate and the silica fume; the component B comprises an inorganic dispersing agent, an organic dispersing agent, a coalescing agent, a plasticizer, a waterproof agent, a weather-proof agent, a defoaming agent and a reaction repairing agent in an optimized ratio. The adhesive force, tensile strength, elongation at break and other properties of the prepared guniting material all reach the industrial indexes. The guniting material has elasticity and toughness, weather resistance, high flame retardance, high strength, flowability, sagging resistance, crack resistance, impermeability, watertightness, high elastic modulus and high elongation at break, has good compressive strength, does not crack after being overloaded and is pressed, the leakproofness of the material is kept, and the service life of the guniting material is prolonged. And a good protection effect is achieved on a pressed and crushed object.
Description
technical field [0001] The present application relates to the field of shotcrete materials, in particular to a shotcrete material and a preparation method. Background technique [0002] Shotcrete plugging is a common method to solve the problem of air leakage caused by coal pillar cracking. However, the existing shotcrete has many drawbacks. For example, the inorganic foam shotcrete material has poor cohesion, thin shotcrete, and long solidification time. When it is subjected to pressure disturbance again, it is prone to cracking and falling off, resulting in poor blocking effect. For another example, the price of the organic foamed resin shotcrete material is expensive, and during the reaction process, a high temperature easily ignites the coal mass, causing hidden dangers in production. SUMMARY OF THE INVENTION [0003] The present application provides a shotcrete and a preparation method to solve the problems of poor sag resistance, crack resistance and weather resista...
