磷酸酯抗燃油用离子交换树脂及其制备方法
摘要：
本发明公开了一种用于磷酸酯抗燃油纯化的离子交换树脂及其制备方法，其目的在于解决现有方案无法有效纯化磷酸酯抗燃油的问题。本发明包括阳离子交换树脂和阴离子交换树脂，所述的阳离子交换树脂为大孔接枝邻苯二酚－聚苯乙烯阳离子交换树脂；所述的阴离子交换树脂由阴离子交换树脂A和阴离子交换树脂B组成，按重量百分比计阴离子交换树脂A占40%~60%，余量为阴离子交换树脂B。本发明通过离子交换作用，阳离子型树脂可有效除去磷酸酯抗燃油中的阳离子如铁离子，钙离子等，提高抗燃油的电阻率，阴离子型树脂可有效除去磷酸酯抗燃油中因水解产生的酸性物质，提高油质。
摘要（英）：

The invention discloses an ion exchange resin for phosphate fire-resistant oil and a preparation method thereof, and the purpose is to solve the problem that present schemes can not effectively purify phosphate fire-resistant oil. The ion exchange resin of the invention comprises a cation exchange resin and an anion exchange resin, and the cation exchange resin is a macroporous grafted catechol-polystyrene cation exchange resin; the anion exchange resin is composed of an anion exchange resin A and an anion exchange resin B, and the anion exchange resin A accounts for 40%-60% on a weight basiswith the balance being the anion exchange resin B. According to the invention, through ion exchange effect, the cationic resin can effectively remove cations such as iron ions, calcium ions and the like in the phosphate fire-resistant oil, and increase the resistivity of the fire-resistant oil, while the anionic resin can effectively remove acidic substances generated by hydrolysis in the phosphate fire-resistant oil, and increase oil quality.
