As can be seen from Table 1, examples 1-3 provide fabricated building insulated exterior wall panels having a low thermal conductivity and good insulation properties. It can be seen from the experimental data comparing example 1 with comparative examples 1-3 that the thermal conductivity of the fabricated building thermal insulation external wall panel provided in example 1 is much smaller than that of the fabricated building thermal insulation external wall panels provided in comparative examples 1-3, which may be caused by the difference of the raw material polymer acrylic emulsion in the thermal insulation concrete slurry, and the polymer acrylic emulsion may affect the thermal insulation performance of the thermal insulation particle material. Therefore, in the process of preparing the high-molecular acrylic emulsion, the gamma-methacryloxypropyltrimethoxysilane graft modified nano calcium carbonate and the gamma-aminopropyltriethoxysilane graft modified aluminum hydroxide are added to synergistically improve the positive influence degree of the high-molecular acrylic emulsion on the heat preservation performance of the heat preservation particle material.
