The present application relates to solid waste recycling technical field, provide a kind of based on coal-based solid waste's anti-dispersion grouting material and its preparation method and application, the material is made of coal gangue, fly ash, silica ash, cellulose, water reducing agent and alkali activator, wherein, alkali activator is made of deionized water, sodium hydroxide and water glass.The based on coal-based solid waste's anti-dispersion grouting material is prepared according to following steps: after mixing coal gangue, fly ash, silica ash, cellulose and water reducing agent, stirring treatment is carried out, and powder precursor is prepared;Alkali activator is added to the prepared powder precursor, and alkali activator is made of deionized water, sodium hydroxide and water glass, continue to stir to prepare the based on coal-based solid waste's anti-dispersion grouting material.The present application can prepare the anti-dispersion grouting material of excellent fluidity, stability and mechanical property, provides innovative path for the resource of coal-based solid waste, significantly reduces material cost, improves environmental benefits and engineering application value.

The application discloses a plugging glue and a preparation method thereof. The plugging glue raw material comprises the following components in percentage by mass: 9-25% of photocuring resin, 0.5-1% of a photo initiator, 70-85% of modified inorganic fillers and 4-6% of modified heat-conducting fillers; the modified inorganic fillers are inorganic fillers modified by a silane coupling agent; and the modified heat-conducting fillers are heat-conducting fillers modified by a silane coupling agent. The photocuring resin, the modified inorganic fillers and the modified heat-conducting fillers are compounded, so that the plugging glue has excellent viscosity and rapid curing performance, the shortcomings of traditional high polymer adhesives are overcome, and the plugging glue can be used for rapidly plugging the inflatable equipment under pressure, and can be applied to the rapid pressure plugging of the sand eye cracks, micro cracks and annular leaking parts of the inflatable equipment.

The application provides a kind of adhesive for flexible composite pipe repair and its preparation method.The adhesive includes modified metal oxide particles, dilution monomer, acrylate prepolymer and photoinitiator;The modifier of modified metal oxide particles is selected from one or more than two combinations of stearic acid, sodium stearate and polyoxyethylene stearate.The adhesive can effectively shorten the construction time, reduce energy consumption and be more environmentally friendly in the process of flexible composite pipe repair.
