Abstract

The invention discloses a spraying rapid-solidification waterproof coating. The coating is characterized by consisting of a bitumen latex and a curing agent, wherein the bitumen latex consists of the following components in parts by weight: 60-65 parts of petroleum asphalt, 30-35 parts of water, 5-7 parts of an emulsifier, 20-35 parts of a neoprene latex and 10-20 parts of a styrene-butadiene latex, and the curing agent consists of, in parts by weight, 10-15 parts of anhydrous calcium chloride and 80-90 parts of water. Because of adoption of the above technical scheme provided by the invention, the spraying rapid-solidification waterproof coating has good low-temperature resistance, flexibility, flexure resistance, tear resistance, ageing resistance and dispersibility. Emulsified asphalt is modified fully, and a calcium chloride solution has extremely strong demulsification speed and property on the modified emulsified asphalt. Films are formed through spraying by using special devices; sprayinging technology is adopted; the efficiency is high; seamless connection is realized; and water channeling does not exist.

Description

technical field [0001] The invention relates to the field of waterproof coatings, in particular to a spraying quick-setting waterproof coating and a production method thereof. Background technique [0002] With the increasing number of urban civil buildings and complex industrial buildings and sewage treatment plants, the requirements for waterproof coating materials are getting higher and higher. The previous waterproof coatings are all solvent-based, and have low elongation and low construction efficiency. Construction period, and improper operation can also cause water leakage, for example, polymer emulsion building waterproof coating, polymer cement waterproof coating, polyurethane, asphalt waterproof coating. Among them, polyurethane and asphalt waterproof coatings contain a large amount of volatile and toxic substances of solvents and isocyanates, which pollute the environment, are not conducive to environmental protection, and do not adapt to current national policies...
