Anti-scaling filtering membrane and preparation method thereof

The invention provides an anti-scaling filtering membrane. The anti-scaling filtering membrane is prepared from the following reagents: a polyetherimide represented by a formula (1) and a polyetheramine cross-linking agent represented by a formula (2). Wherein n is an integer, and 50 < = n < = 70. Wherein a, b and c are integers, and (a + c) < = b. The anti-scaling filtering membrane disclosed by the invention can achieve a good anti-scaling effect, so that the anti-scaling filtering membrane has high filtering efficiency and long service life. 本揭露内容提供一种抗结垢过滤膜，其是藉由包括以下试剂制备而成：以式(1)表示的聚醚酰亚胺以及以式(2)表示的聚醚胺交联剂。其中n为整数，且50≦n≦70。其中a、b及c为整数，且(a+c)≦b。本揭露的抗结垢过滤膜可达到良好的抗结垢效果，从而具有高过滤效率以及长使用寿命。
