Abstract
In this article,3-(diethoxymethylsilyl)propyl methacrylate(MPTS) was used as modifying functional monomer,acrylic ester and acrylic acid as main monomers,ionic emulsifiers and nonionic emulsifiers as the composite emulsifier,persulfate(KPS) as initiator,and the silicone modified acrylate copolymer emulsion(SAE) was successfully prepared.The relationship between the stability of SAE emulsion and contents of MPTS,β-hydroxypropyl methacrylate(HPMA),initiator and copolymerization temperature were investigated.IR and TG were used to characterize SAE.The SAE copolymer emulsion was applied in the preparation of silicones-acrylate copolymer humidity coating(SAE-C) with the addition of pigments and fillers,such as diatomite,bentonite,etc.By measuring the basic performance of copolymer emulsion film and SAE-C coatings,the humidifying function of SAE-C coating was investigated.In conclusion,MPTS could improve the adhesion of SAE film and water resistance of the coating.The results show that the basic properties of SAE and SAE-C match the standard for interior wall coatings.The obtained coatings had good humidity-sensitivity and humidity retention,which could be used as the interior wall coating in the building.
