Abstract

The invention discloses a special permeable masterbatch for producing a PE (poly ethylene) permeable membrane and a preparation method of the permeable masterbatch. The special permeable masterbatch for producing the PE permeable membrane comprises the following components in parts by weight: 100 parts of PE resin, 30-80 parts of a compound permeate agent, 20-60 parts of a filler, 5-20 parts of a lubricating dispersant and 0.1-0.6 parts of an antioxidant. The preparation method comprises the following steps: mixing the PE resin, the compound permeate agent, the filler, the lubricating dispersant and the antioxidant in a high-speed mixing machine until the temperature of the materials rises to 30-50 DEG C as a result of the friction heat generated by mixing, then discharging and cooling; feeding the cooled materials into a double-screw extruder, performing fusion and extrusion, cooling the extruded materials through a water tank, and pulling into a granulator and granulating to obtain the masterbatch. The special permeable masterbatch for producing the PE permeable membrane has the advantages of no toxicity, cleanness, low cost and the like, and the PE permeable membrane produced by the special permeable masterbatch is favorable in wetting property.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a permeable masterbatch specially used for PE permeable membrane production and a preparation method thereof. Background technique [0002] Because of its strong water absorption, hygienic safety, and convenient use, PE non-woven fabrics are widely used in medical, sanitation, industry, agriculture and other fields. They are revolutionary products that replace traditional fabrics and paper. [0003] Since ordinary PE film is a hydrophobic material, it has no water absorption. Therefore, the PE film for the preparation of PE non-woven fabrics is a water-absorbent PE permeable membrane, which is made by blending PE resin (including LDPE resin and LLDPE resin) with special permeable masterbatches, and then made by casting or blow molding. PE cast film or PE blown film. The PE permeable membranes currently on the market have the problem of poor wettab...
