Method for preparation of polyolefin microporous membrane by wet process |
| abstract |
The invention relates to a method for preparation of a polyolefin microporous membrane by a wet process. According to the method, polyolefin resin, an antioxidant and liquid paraffin are adopted as raw materials for preparation of the microporous membrane through a thermally induced phase separation method. Employment of the preparation method provided in the invention can effectively prevent thermal oxidative degradation and carbonization phenomena in a high temperature processing process of polyolefin resin. The antioxidant and the polyolefin resin are mixed and dispersed more uniformly, and the antioxidant can be removed during liquid paraffin extraction, so that the pure and high performance polyolefin microporous membrane can be obtained. |
