Embodiment 1

[0031] In this embodiment, the preparation process of the waterproof polymer material is as follows:

[0032] Put 0.06 parts of modified nano-magnesium oxide and 0.08 parts of dispersant in 9 parts of water, stir for 240s, and then put it under the power of 700W for 0.5h to obtain a uniform mixed solution; then weigh 40 parts of fly ash, 26 Pour phosphorus slag, 10 parts of ordinary Portland cement, 7 parts of sodium bentonite into the mixing pot, stir for 90 seconds to obtain the mixture particles, then mix the obtained mixture particles, 0.01 parts of admixture, 4 parts of sodium hydroxide solid and Add 5 parts of sodium silicate solids into the muffle furnace (setting temperature is 800°C), calcinate for 5 hours, sieve after cooling to obtain geopolymer colloid powder; then add the homogeneous mixed solution obtained above to the above geopolymer Stir in the colloidal powder for 240s to obtain a geopolymer slurry, then pour, vibrate, and cure under natural conditions to obt...

Abstract

The invention discloses a waterproof polymer material and a preparation method thereof. The invention is composed of raw materials such as fly ash and ordinary portland cement, and is composed of admixtures such as nano-magnesium oxide, and the geopolymer has good construction performance, and at the same time has compressive strength, good bonding strength development, and shrinkage performance. Good, good impermeability and other characteristics. The invention can make full use of fly ash solid waste, not only can solve the problem of solid waste stacking, and turn waste into treasure, but also the prepared waterproof geopolymer material can be used for repairing cracks in tunnel lining and other parts. The waterproof geopolymer material of the present invention omits the configuration process of the alkali excitation solution, realizes normal temperature preparation, and has a simple preparation method, low cost, and is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of geopolymer-based materials, in particular to a waterproof geopolymer material and a preparation method thereof. Background technique [0002] "Ten Tunnels and Nine Cracks" describes the general situation of cracks in tunnels today. Tunnel cracks are the main cause of tunnel water leakage and other diseases, and are also common diseases in tunnel construction and operation. Among the many diseases and problems in tunnels, cracks in tunnel lining structure are relatively common, and they are more harmful. The occurrence and development of cracks not only promote each other with water leakage and regional deterioration of lining, but also directly affect the quality of tunnels. The safe bearing of the lining structure forms a vicious circle and accelerates the destruction process of the lining structure. At present, the treatment measures for tunnel lining cracks include two aspects. One is to improve the s...
