Method for preparing nano-modified styrene-acrylic/siloxane graft copolymerized composite emulsion
A method for preparing a nano-modified styrene-acrylic/siloxane graft copolymerized composite emulsion. The prepared composite emulsion has a styrene-acrylic molecule with a glass transition temperature that gradiently changes and a siloxane molecular chain, both of which are bonded together by means of a strong covalent bond, such that the cross-linking degree and compatibility of the styrene-acrylic component and the siloxane component can be effectively improved at a nanoscale level. The emulsion enables a treated cement-based material to simultaneously form a surface protective layer and an internal crystalline waterproof layer, such that the composite protective emulsion is endowed with good rheological properties, waterproof performance, ion permeation resistance, carbonization resistance, acid and alkali corrosion resistance, and aging resistance.
