Example Embodiment
[0027] Example 1
[0028] Water 15%, silicone rubber emulsion 5.37%, sodium lauryl benzoxanthate emulsion 0.5%, phthalic acid 26.5%, S-100 emulsifier 15%, 5040 dispersant 2%, sodium chloride 0.02%, Vinyl caproate 10%, isooctyl alcohol 0.01%, bentonite 1%, heavy calcium carbonate 12%, wollastonite 10%, iron oxide 0.5%, silicon dioxide 1%, iron oxide yellow 0.1%, defoamer 1%
[0029] The preparation method includes the following steps:
[0030] (1) Dissolve sodium chloride with 5% water and set aside;
[0031] (2) Mix sodium dodecyl benzoxanthate and silicone rubber emulsion, stir mechanically for 5 minutes, and then set aside;
[0032] (3) Mix S-100 emulsifier and phthalic acid, add 5% water to disperse for 5 minutes, then add the sodium chloride solution prepared in step (1), stir mechanically for 10 minutes, and place it in the suction tank. After the suction is completed, disperse for 15-20 minutes;
[0033] (4) Add vinyl acetate and 5040 dispersant to the suction tank for sucti...
