NOVELTY - Modified polyethylene breathable master batch comprises 40-70 pts. wt. polyethylene, 0.5-2.5 pts. wt. talc, 35-60 pts. wt. calcium carbonate, 0.1-2 pts. wt. antioxidant, 0.1-2 pts. wt. stabilizer and 80-110 pts. wt. modified graphene dispersion liquid; the modified graphene dispersion liquid includes 0.1-2 pts. wt. graphene, 0.1-1 pts. wt. dispersant and 60-100 pts. wt. solvent. USE - The master batch is useful for preparing ultra-thin breathable film. ADVANTAGE - The modified polyethylene breathable master batch: can actively improves the mechanical properties of the polyethylene material, and realizes the preparation of ultra-thin breathable film with smaller gram weight; and is simple to prepare, economical and environmentally friendly, and can realizes large-scale continuous production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the modified polyethylene breathable master batch comprising (1) weighing polyethylene, talc, calcium carbonate, antioxidant, and stabilizer, stirring, melting, extruding, granulating into particles, and drying; and (2) completely soaking the polyethylene particles obtained in step (1) in the modified graphene dispersion liquid, heating and stirring, removing the solvent, and air drying to obtain the modified polyethylene breathable master batch.
