Abstract

The invention discloses amine-free waterproof emulsion, and belongs to the technical field of waterproof coatings. The amine-free waterproof emulsion comprises, by weight, 40-50 parts of deionized water, 0.6-12.0 parts of emulsifying agent, 0.02-20 parts of phosphoric acid ester monomers, 0.05-40 parts of hydrophilic monomers, 0.05-60 parts of hydrophobic monomers, 0.05-20 parts of polymerization stabilizer, 0.02-5 parts of vinyl silicone, 0.02-5 parts of initiating agent, 0.02-5 parts of chain transfer agent, 0.02-5 parts of pH buffering agent, 0.02-5 parts of antifoaming agent, 0.02-5 parts of preservative and 0.02-5 parts of alkali liquid. The invention further provides a preparing method of the amine-free waterproof emulsion and a waterproof coating containing the amine-free waterproof emulsion. The waterproof emulsion and the waterproof coating are environmentally friendly and free of pollution, and pungent smells such as ammonia smells are not generated.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, and relates to a waterproof emulsion and a preparation method thereof, in particular to an amine-free waterproof emulsion, a preparation method thereof and a waterproof coating containing the amine-free waterproof emulsion. Background technique [0002] my country is a large manufacturing country. With the expansion of the economy, the national outbreak of environmental pollution and severe atmospheric smog has seriously threatened the environment on which the people of the country depend. VOC in coatings and adhesives is the cause of severe atmospheric smog. The culprit of smog is the most important cause of smog. Although the current performance of water-based coatings cannot exceed that of traditional solvent-based coatings, it has become an inevitable development trend of waterproof coatings because of its pollution-free, environmental protection and compliance with national enviro...
