Kind Code:
A1
Abstract:
A quick-setting waterproof spray coating for marine anticorrosion and a preparation and construction method therefor. The coating consists of material A and material B. The material A consists of the following components by weight percentage: 40-65% of emulsified asphalt, 27-50% of rubber latex, 8-20% of zinc oxide dispersion liquid, 5-15% of filler slurry, 0.05-3% of sodium silicate aqueous solution, 1.5-2.5% of antiaging agent, 0.03-0.08% of mould-proof bacteriostatic agent, and 0.1-0.3% of defoaming agent; the B material consists of the following components by weight percentage: 5-20% of a soluble metal salt which does not contain chloride ions, 1-5% of ethylene glycol, 0.1-0.5% of alkyl polyoxyethylene ether, and deionized water as balance. A waterproof coating film for marine anticorrosion, prepared from the coating, has good chloride iron penetration resistance and excellent waterproof and antibacterial effects, and can be used for marine construction waterproofing.
