Novel stone waterproof gum
The invention relates to novel stone waterproof gum which comprises liquid and powder according to the weight ratio of 1:2-1:3. The liquid comprises 50-70% of acrylic copolymer emulsion and 29.2-49.2% of water, and the percent refers to a percent accounting for the total weight of the liquid. The powder comprises 20-80%, preferably 30-41.5% of cement, 20-80%, preferably 50-60% of quartz sand, 1.0-5.0%, preferably 0.5-1.0% of polyvinyl alcohol, and 0.1-3.0%, preferably 0.5-2.0% of water repellents, and the percent refers to a percent accounting for the total weight of the powder. The novel stone waterproof gum has the advantages that a cross-linking network structure of a coating is compact, flexible, firm and strong in waterproof and alkali-resistant function, water and salt are effectively blocked, spotting and whitening are prevented, the coating is excellent in adhesive property and fine in stone reinforcing function, and damage to stones in the carrying process is decreased.
