Low-Tg acrylate emulsion for cement-based building materials, and preparation method thereof
The invention relates to low-Tg acrylate emulsion for cement-based building materials. The acrylate emulsion is composed of latex particles with a soft-core hard-shell structure. The emulsion Tg is -30 DEG C to 5 DEG C, the core Tg is -50 DEG C to -5 DEG C, and the shell Tg is -5 DEG C to 20 DEG C. The proportion of core is 70-95%, and the proportion of shell is 5-30%. The principle of the emulsion provided by the invention is that low-Tg core-shell-structured latex particles are synthesized with a core-shell polymerization process; and with the protection of the shells to the soft cores, the problem of the adaptability of low-Tg acrylate emulsion and cement is solved. Therefore, the application range of the low-Tg acrylate emulsion is expanded.
