Abstract

The invention discloses an even-structure and high-permeability microporous membrane used for filtering. The even-structure and high-permeability microporous membrane is prepared from the following raw materials in parts by weight: 100-110 parts of polyethylene, 27-30 parts of acrylonitrile, 0.1-0.2 part of dicumyl peroxide, 2-4 parts of plasticizer, 1-2 parts of antimonous oxide, 0.8-1 part of zinc borate, 1-2 parts of antioxidant, 0.8-2 parts of heat stabilizer, 1-2 parts of 2-Octyl-3(2H)-isothiazolone, 1-3 parts of calcium propionate, 0.7-2 parts of triglycidyl isocyanurate, 4-6 parts of diacetone alcohol, 0.7-1 part of oleic diethanolamide, 0.5-1 part of sodium myrastate and 1-2 parts of glycolic acid. Compared with other existing technologies, the process technology disclosed by the invention has the advantages of simple technology, high yield and efficient production efficiency and is suitable for large-scale continuous production, and production cost is lowered; in addition, polyolefin is adopted, so that the price of raw materials is low, and finally, the cost of an air filtering membrane is greatly lowered.

Description

technical field [0001] The invention relates to the field of filter membrane materials, in particular to a microporous membrane with uniform structure and high air permeability for filtration and a preparation method thereof. Background technique [0002] In recent years, with the deterioration of the environment such as smog and sandstorms, people's health has been seriously endangered whether they are at home or in public places. In addition, due to the improvement of living standards and the popularization and use of air-conditioning, it has entered thousands of households. In summer, the air in closed spaces where air-conditioning is used for a long time is turbid and the quality is extremely bad, leading to more and more people suffering from air-conditioning syndrome, such as poor sleep quality. There are many situations that seriously affect your health, such as poor immunity and weakened immunity. Even if the air conditioner is not used in winter, the long-term clos...
