Abstract

The invention provides a porous adsorption gas-permeable membrane and a preparation method thereof, which relate to the technical field of high molecular materials. The porous adsorption gas-permeablemembrane provided by the invention is prepared from the following raw materials: polyethylene, polypropylene, a porous adsorption powder body, an elastomer, a surface treating agent and a lubricatingagent. The porous adsorption gas-permeable membrane provided by the invention is excellent in waterproofness and gas permeability, watertight, higher in gas permeability, and capable of enabling gasiform water molecules to smoothly pass through, achieves the effect on timely discharging moisture, is not stuffy when in use, and can be directly used as a waterproof material or widely applied to various fields with requirements on gas permeability and waterproofness; the porous adsorption powder body with a specific function is added into a raw material formula for preparing the porous adsorption gas-permeable membrane, so that without influencing the gas permeability of the material, a waterproof function of the gas-permeable plastic membrane is greatly improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a porous adsorption gas permeable membrane and a preparation method thereof. Background technique [0002] The breathable film is a kind of polymer filled with a certain proportion of mineral fillers, which forms a controllable space around the filler, which allows water vapor, air and other gases to pass through, but does not allow liquids to pass through. It is used in the production of baby diapers, women's sanitary napkins, Baby diapers, medical protective clothing and warm and cold packs (heating stickers), protective equipment, food packaging (such as plastic wrap, composite film, cooked food packaging bags, etc.) It is widely used in agriculture and home furnishing. For China with such a large population base, there is a large market space and a great demand. [0003] Among the commonly used breathable membranes at present, composite breathable membranes made of...
