Waterproof material
The invention discloses a waterproof material. The waterproof material is prepared from the following components in parts by weight: 15-25 parts of polyvinyl alcohol, 4-8 parts of calcined kaolin powder, 3-6 parts of calcined vermiculite power, 0.5-2 parts of hydroxypropyl methyl cellulose ether, 3-5 parts of 4,6-dihydroxypyrimidine, 8-10 parts of 1,2,4-triazo[4,3-a]pyrazine-3-carboxylic acid ethyl ester, 6-8 parts of sodium hydroxide, 9-16 parts of potassium chloride, 20-25 parts of sodium fluoride and 50-65 parts of water. When the waterproof material is applied indoors, a spray-coating construction method can be adopted, and the material is capable of permeating into the concrete of the lower layer along the gaps and the microcracks of the leakage parts of ceramic tiles and further permeating into the hairline cracks of the concrete for waterproof repair; and when the waterproof material is applied outdoors, the waterproof material has excellent impact fatigue property, and is capable of effectively resisting high-frequency repeated impact caused by rainstorm and hailstorms.
