[0021] A preparation method for grouting material, comprising the steps of:
[0022] (1) Take polyethylene glycol 200 and mix it with glycerin at a mass ratio of 8:3 to obtain a mixture. Take the mixture and add starch at a mass ratio of 6:1, then add methanesulfonic acid with a mass ratio of 3 to 5% of the mixture, and heat up to 140~ Stir and mix at 150°C for 2~3h, cool to 60~80°C to obtain a cooled product, take the cooled product and add 10% sodium hydroxide solution with a mass fraction of 5:2, stir and mix for 20~30min to obtain a stirred mixture;
[0023] (2) Take the stirred mixture and raise the temperature to 110~115°C, vacuum dehydrate at -0.09~-0.1MPa for 2~3h, cool to 50~60°C, and add 50~70% of the mass of the stirred mixture to diphenyl Methane diisocyanate, stirred and mixed at 75~80°C for 3~4h to obtain mixture A, in parts by mass, take 20~30 parts of mixture A, 12~15 parts of hydroxypolydimethylsiloxane, 50~70 parts Acetone, 2~5 parts of N,N-dimethylcyclohexy...

Description
technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of a grouting material. Background technique [0002] The grouting material is made of high-strength materials as aggregate, cement as binder, supplemented by high fluidity, micro-expansion, anti-segregation and other substances. It adds a certain amount of water at the construction site, and it can be used after stirring evenly. The grouting material has the characteristics of good self-flowing property, rapid hardening, early strength, high strength, no shrinkage, and slight expansion; non-toxic, harmless, non-aging, no pollution to water quality and surrounding environment, good self-tightness, and anti-rust. In terms of construction, it has the advantages of reliable quality, reduced cost, shortened construction period and convenient use. Fundamentally change the stress on the base of the equipment, so that it can evenly bear all the loads ...
