[0040] The preparation method of polymer material provided by the invention comprises:
[0041] a, the water phase comprising water, dispersant and auxiliary dispersant and the oil phase comprising the organic compound of -C=C-, the organic compound of -C=C- and initiator are mixed to carry out suspension polymerization to prepare into the matrix polymer,
[0042] The weight ratio components contained in the water phase are water: dispersant: auxiliary dispersant = 800~1000: 0.5~3.0: 0.05~0.2, and the weight ratio components contained in the oil phase are organic compounds containing -C=C- : organic compound containing -C=C-: initiator = 0.75~0.98: 0.02~0.25: 0.003~0.01, the weight ratio of oil phase and water phase is 1: 4~6.
[0043] The dispersant is one or both of inorganic dispersant or organic dispersant, the inorganic dispersant is one or more of silicate, carbonate or phosphate, and the organic dispersant is polyethylene Alcohol, gelatin, carboxymethylcellulose or poly...

[0060] (1) Polymerization: Add 18 liters of pure water to a 50-liter polymerization kettle, heat to 45°C, add 10 g of magnesium carbonate, 20 g of gelatin and 0.15 g of methylene blue under stirring, and add 3 kg of benzene Ethylene, 1kg divinylbenzene, 20g benzoyl peroxide mixed oil phase. Close the reactor, feed clean compressed air into the reactor, and keep the gas phase pressure in the reactor at 0.02MPa. Turn on the stirring, adjust the liquid beads to an appropriate particle size, raise the temperature to 80°C, keep warm for 12 hours, then raise the temperature to 100°C, keep warm for 20h, filter, wash, dry, and sieve to obtain 2.57kg of white balls with a particle size of 0.5-0.8mm.
[0061] (2) Sulfonation: Add the spheres obtained after polymerization into a 50-liter reaction kettle, add 10kg of 105% oleum, heat up to 110°C, keep warm for 16 hours, cool down, slowly add pure water dropwise, and draw out 1 / 2 3 liquid, continue to add pure water dropwise, operate in t...
