Abstract

The invention discloses a tear-resistant anti-seepage plastic bag. Raw materials of the plastic bag comprise (by weight): 65-85 parts of polypropylene, 4-12 parts of benzoyl peroxide polyester, 2-8 parts of terpolymer EP rubber, 4-10 parts of a reinforcing filler, 0.2-0.5 part of zinc oxide, 0.2-0.6 part of maleic anhydride, 1-2 parts of a plasticizer, 14-25 parts of a compound lubricant, 1-2 parts of an anti-aging agent, 0.2-0.8 part of a release agent, and 0.2-1 part of a light stabilizer. The plasticizer comprises the following ingredients (by weight): 0.1-0.6 part of 9,10-octyl epoxy stearate , 0.1-0.4 part of butyl phthalate and 0.5-1.2 parts of epoxidized soybean oil. The compound lubricant is prepared by the following process: adding humic acid into a sodium hydroxide solution, heating and stirring, adjusting the system to neutral level, adding carbon nanotube, magnesium stearate and microcrystalline wax, heating and stirring, grinding, centrifuging, removing an upper solution,and drying the lower layer of solids to obtain the compound lubricant.

Description

technical field [0001] The invention relates to the technical field of plastic bags, in particular to a tear-resistant and anti-leakage plastic bag. Background technique [0002] At present, the plastic bags sold in the market are used to hold items.
