Abstract

The invention belongs to the field of an inorganic waterproof leaking stoppage material and specifically provides a reinforcing anti-cracking solution for a quick leaking stoppage material and a preparation method thereof. The formula of the reinforcing anti-cracking solution contains the following components by weight percent: 18-25% of aqueous epoxy acrylic emulsion, 2-5% of aqueous amino resin, 0.09-0.4% of polyvinyl alcohol, 0.05-0.15% of cellulose ether, 0.2-0.45% of starch ether, 0.1-0.24% of lithium sulfate, 0.2-0.9% of calcium chloride, 0.04-0.08% of 2-amino-2-methyl-1-propyl alcohol, 1-2% of de-foaming agent and the balance of water. When the reinforcing anti-cracking solution is applied to the quick leaking stoppage material, the anti-cracking capacity of the quick leaking stoppage material can be greatly promoted, and meanwhile, the curing time is not delayed and the bonding strength and cohesion strength of the quick leaking stoppage material can be promoted.

Description

technical field

[0001] The invention belongs to the field of inorganic waterproof plugging materials, and in particular relates to a reinforcing and anti-cracking liquid used in fast plugging materials and a preparation method thereof. Background technique

[0002] Existing inorganic waterproof plugging materials are mainly composed of rapid hardening cement, aggregate, water reducing agent, cellulose ether and other materials, and a certain proportion of water is added during use, and then used for rapid plugging after mixing evenly.

[0003] The current waterproof plugging materials have the following problems and disadvantages: (1) The plugging material often cracks when it is cured and formed in the later stage; (2) The bonding strength with the base layer is not strong; (3) The strength will weaken significantly when the amount of water is added too much , and a large number of cracks will appear.
