Abstract

The invention provides a spraying quick-setting waterproof coating for marine corrosion prevention and a preparation method and construction method thereof. The spraying quick-setting waterproof coating is composed of a material A and a material B, wherein the material A is prepared from the following components in percentage by weight: 40 to 65 percent of emulsified asphalt, 27 to 50 percent of arubber emulsion, 8 to 20 percent of a zinc oxide dispersion liquid, 5 to 15 percent of filler slurry, 0.05 to 3 percent of a sodium silicate aqueous solution, 1.5 to 2.5 percent of an anti-aging agent, 0.03 to 0.08 percent of a mildew-proof bacteriostatic agent and 0.1 to 0.3 percent of a defoaming agent, and the material B consists of the following components in percentage by weight: 5 to 20 percent of a chloride ion-free soluble metal salt, 1 to 5 percent of ethylene glycol, 0.1 to 0.5 percent of alkyl polyoxyethylene ether and the balance of deionized water. The prepared waterproof coatingfilm for marine corrosion prevention is good in chloride ion permeability resistance and good in waterproof and antibacterial effects, and can be used for marine building waterproofing.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a spraying quick-setting waterproof coating for marine anticorrosion and its preparation and construction method. Background technique [0002] High Cl in marine environment - The concentration has a corrosive effect on the concrete of the building and the steel bars in the concrete, seriously affecting their service life; and the high humidity in the marine environment will make the building moldy, affecting the performance and appearance of the building. Therefore, the high salinity and high humidity of the marine environment put forward higher requirements for the protective materials of buildings. Therefore, for the waterproofing of buildings in marine areas, our company has developed a corrosion-resistant chloride ion permeability and antibacterial properties. Spray quick-setting waterproof coating for marine anticorrosion. Contents of the invention [0003...
