Polysiloxane-modified emulsion has good comprehensive performance

Guangzhou Chemical Co.
, Ltd.
, Chinese Academy of Sciences, recently developed a cross-linked polysiloxane/acrylate compound emulsion
.

The preparation process of the emulsion is: silicone monomer, water and composite emulsifier prepare siloxane monomer emulsion by shear emulsification and high pressure homogenization, then add cross-linking agent to prepare cross-linked polysiloxane emulsion, and finally cross-linked polysiloxane emulsion and polyacrylate emulsion prepared by continuous emulsion polymerization method are compounded by a simple process to obtain a stable and compatible cross-linked polysiloxane/acrylate compound emulsion
。 The compound emulsion not only has the characteristics of good hydrophobicity, high/low temperature resistance, water resistance, alkali resistance and stain resistance of polysiloxane emulsion, but also has the characteristics of good film-forming, weather resistance, ozone resistance and ultraviolet resistance of acrylic emulsion, which can be used for architectural coatings
such as interior walls, exterior walls, floors, and toilets.
