1results about How to "Improve low temperature flexibility" patented technology

This invention belongs to the field of building materials technology, specifically relating to a high-flexibility emulsion, its preparation method, and its application in flexible ceramics. The high-flexibility emulsion uses methyl methacrylate, isooctyl acrylate, hydroxyethyl acrylate, and modifier A as core monomers; and methyl methacrylate, styrene, hydroxyethyl acrylate, and modifier B as shell monomers, prepared using a monomer pre-emulsification semi-continuous seed emulsion polymerization process. Modifier A is obtained by reacting epoxidized cashew nut shell powder with a mercapto compound; modifier B is obtained by reacting carboxybenzotriazole, epoxy silane, and epoxy acrylate. This invention prepares a core-shell structured high-flexibility emulsion using a monomer pre-emulsification semi-continuous seed emulsion polymerization process. By introducing specific modifiers A and B into the core and shell monomers, the low-temperature flexibility, frost resistance, tensile properties, and weather resistance of flexible ceramics are optimized.
