Abstract

The invention discloses a diaphragm material for purifying sewage. Raw materials of the diaphragm material comprise, by weight, 175 parts of ethylene propylene rubber, 20-30 parts of intermediate super abrasion carbon black, 80-90 parts of fast extruding carbon black, 45-55 parts of thermal decomposition process carbon black, 50-60 parts of naphthenic oil, 3-8 parts of indirect zinc oxide, 0.5-1.5 parts of stearic acid, 2.5-4.5 parts of polyethylene glycol, 2.5-4.5 parts of a lubricant, 1-1.5 parts of sulphur and 3-5 parts of a promoter. The invention also discloses a preparation method of the above diaphragm material for purifying sewage. The diaphragm material of the invention has high mechanical property and low expandability.

Description

technical field [0001] The invention relates to the technical field of membranes for purifying sewage, in particular to a membrane material for purifying sewage and a preparation method thereof. Background technique [0002] Since entering the 21st century, the global industry, especially China, has developed faster and faster, and at the same time, the pollution caused by it has become more and more serious. Among them, sewage pollution is one of the important ways, whether it is harmful to human health or have had adverse effects on the environment. Therefore, in today's advocacy of environmental protection, the control of industrial pollution is becoming more and more important, and corresponding sewage treatment plants and sewage treatment systems have emerged as the times require and are more and more widely used. The core part of the sewage treatment system is the aeration pan, and the membrane is used to filter and purify the sewage in the aeration pan. The quality o...
