[0062] 1. * indicates a bleaching process stage, so the * number in the process indicates the number of process stages implemented. It also means washing with water. For example: BC(2)P(1)P(2)* represents a process section in the bleaching process, which is continuously treated with the combined agent BC(2) and with the process P(1)P(2). BC(2)P(1)P(3)*BA(2)P(6)* means the combination of two process sections. Before the end of the process section, solid-liquid separation is required, and the obtained resin is washed with water, and then the resin is obtained through solid-liquid separation before entering the next process section.

[0063] 2. r means to repeat the previous bleaching process, for example: BP(1)P(1)P(6)*BF(2)P(8)*r means: BF(2)P(8) It is implemented twice in a row, it is two bleaching stages; R means repeating all the bleaching process stages before *, for example: BC(2)P(1)P(3)*BA(2)P(6)*R Indicates: BC(2)P(1)P(3)*B...

Abstract

The present invention relates to a preparation method of resin material. It uses the industrial-grade sodium polystyrene sulfonate resin and makes it undergo the combined treatment of bleaching and purification, its sulfonation temperature is 100deg.C, so that the light color high-purity sodium polystyrene sulfonate cation exchange resin can be obtained. Said invention also provides the concrete steps of its bleaching process and purification process.

Description

technical field [0001] The invention relates to a preparation method of a resin material, in particular to a preparation method of a light-colored high-purity polystyrene sodium sulfonate cation exchange resin with a sulfonation temperature ≥ 100°C. Background technique [0002] Sodium polystyrene sulfonate cation exchange resin is an auxiliary drug for the treatment of hyperkalemia. Its mechanism of action is to exchange sodium in the resin with potassium in the human body, that is, to absorb potassium ions in the human body and release the potassium ions in the resin. The sodium ions in the resin will be excreted together with the potassium in the body, thereby reducing the potassium content in the blood. For patients with hyperkalemia who need hemodialysis, adjuvant treatment with sodium polystyrene sulfonate can prolong the dialysis cycle and reduce the number of dialysis. It not only reduces the suffering of patients but also reduces the economic burden of patients. A...
