Example Embodiment
[0041] Example 1
[0042] A water-resistant gypsum emulsion of the present embodiment, the feedstock comprises the following weight components:
[0043] 80 gypsum;
[0044] Silica bit 20 parts;
[0045] 16 copies of boron sand
[0046] 5 copies of alumina;
[0047] 4 parts of activated carbon;
[0048] 20 copies of cement;
[0049] 28 s illumination emulsion;
[0050] 3 parts of hydroxypropyl methylcellulose;
[0051] 5 parts of polyacrylamide.
[0052] The solid content of the epoxic acid emulsion is 25%.
