Research of Properties and Preparation on Zero-VOC Acrylic Elastic Emulsion

Abstract

The core-shell acrylic emulsion was synthesized，with P(MMA/BA) as core，and with P(2-EHA/MBA/HPA) as shell. The influence of the mass ratio of core/shell on mechanical properties was investigated in detail. The high elongation at break proved that the emulsion may have a potential application in coating industry, afforded by HPA as functional monomer. However, when the amount of HPA exceeds 1.5 wt. % to the total monomers, the emulsion will become unstable and precipitation occurs.

Comparison on Reduction of VOCs Emissions from Radiata Pine (Pinus Radiata D. Don) between Sodium Bicarbonate and Ozone Treatments

“…It has been found that the sodium hydroxide solution can partially remove terpenes and aldehydes from pine extract [18]. Sodium bicarbonate has been used as a buffer to significantly reduce the VOC contents in styrene-acrylate emulsion [20] and acrylic elastic emulsion [21]. Additionally, researchers have found that treating cannabis leaves with sodium bicarbonate could inhibit their VOC acidity and reduce aldehyde emissions [22].…”

Application of a Novel Initiator on Acrylic Emulsion Polymerization

“…The development of water-based coatings has been an irreversible trend with the social progress and the people's life improvement [1]. As one of the main film forming material of water-based coatings, acrylic emulsion has recently been widely studied.…”
