Compared with the comparative example 1, the polysiloxane quaternary ammonium salt is added in the examples 20 to 21, so that the tensile strength of the flexible soft porcelain is improved, and the sterilization rate of the surface of the flexible soft porcelain is improved;
example 2 and examples 20-21 show that in the range of 5-10Kg of the mass of the quaternary ammonium polysiloxane, the more the quaternary ammonium polysiloxane is added, the greater the tensile strength and sterilization rate of the flexible soft porcelain;
compared with example 21, comparative example 2 shows that when the addition amount of the polysiloxane quaternary ammonium salt exceeds 10Kg, the tensile strength of the flexible soft porcelain becomes small, but the sterilization rate is still increased.
Compared with the comparative example 3, the ammonium chloride is added in the examples 22 to 23, so that particles such as ore sand and the like in the high-molecular emulsion are quickly suspended and dispersed, the leveling property of the emulsion is further improved, and the tensile strength of the flexible soft porcelain is improved;
example 2 and examples 22-23 show that the more ammonium chloride is added, the greater the tensile strength of the flexible soft porcelain, in the range of 5-10Kg of ammonium chloride;
in comparison with example 23, comparative example 4 shows that when the amount of ammonium chloride added exceeds 10Kg, the tensile strength of the flexible soft porcelain becomes small.
