Embodiment 1
[0088] Embodiment 1: A kind of carboxylated styrene-butadiene latex, wherein the components included are as shown in Table 1, and are prepared through the following steps:
[0089] S1, under vacuum conditions, uniformly mix the first solvent, sodium stearate, acrylic acid, N-methylol acrylamide, acrylamide, and pH regulator in the corresponding weight fraction of the water phase material to form the water phase material;
[0090] S2, under vacuum conditions, the corresponding weight fractions of styrene, butadiene, and ethyl 3-mercaptobutyrate in the oil phase material are mixed uniformly to form the oil phase material;
[0091] S3, mixing the mbs seed latex, sodium dodecylbenzene sulfonate, and liquid caustic soda mixture of the corresponding weight fraction in the primer to form a primer;
[0092] S4, under vacuum conditions, take the fourth solvent in other materials, 260 parts of the water phase material obtained in the step S1, 555 parts of the oil phase material obtained...
Embodiment 2-5
[0097] Example 2-5: A carboxylated styrene-butadiene latex, the difference from Example 1 is that the components included in it are shown in Table 1.
