Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described below, so as to make the technical solution of the present invention easier to understand and grasp.

[0019] A preparation formula for an anion exchange membrane, the raw materials of the formula and the parts by weight of the raw materials are: anion resin, 5000-7000 parts; low-density polyethylene (LDPE), 1250-1800 parts; chlorinated polyethylene (CPE), 600-930 parts parts; polyisobutylene (PIB), 300-520 parts; polyethylene wax, 70-120 parts; EBS, 10-20 parts; antioxidant, 3-5 parts. Among them, the anionic resin is washed several times with washing water to remove impurities such as suspended solids and blocks, and is washed until the pH value is neutral. Discharge at 68°C, and after cooling, grind and sieve powder in turn. The anion resin red sieve specification is 100 mesh. Ethylene wax, EBS, and antioxidant are mixed by roller pressure, mixed with internal pressure until compl...

Abstract

The invention provides a preparation formula of an anion exchange membrane, wherein the formula comprises the raw materials in parts by weight: 5000-7000 parts of anion resin; 1250-1800 parts of low density polyethylene (LDPE); 600-930 parts of chlorinated polyethylene (CPE); 300-520 parts of polyisobutylene (PIB); 70-120 parts of polyethylene wax; 10-20 parts of EBS; and 3-5 parts of an antioxidant. The anion exchange membrane prepared by implementing the technical scheme has the advantages of small pressure water permeability, small resistance, high chemical stability, and acid and alkali resistance.

Description

technical field [0001] The invention relates to an ion exchange membrane, in particular to a preparation formula of an anion exchange membrane. Background technique [0002] Ion exchange membrane is a key component of electrodialyzer, which has certain selectivity and conductivity, including cation exchange membrane and anion exchange membrane, which are widely used in the electrochemical department to separate different types of ions, such as seawater, brackish water Desalination, desalination and concentration of solutions, electrolytic production of inorganic compounds and recovery and purification of radioactive elements, softening and desalination of boiler water, treatment of industrial products such as electronics, medicine, chemicals, food, coal, and metallurgy. Ion exchange membranes with different structures and different methods have obvious differences in ion selectivity, exchange capacity, resistance, water permeability, and chemical and mechanical stability. A...
