Abstract

The invention discloses a method for preparing a flame-retardant flexible freight bag. The method comprises the following operating steps: (1) uniformly mixing melamine cyanurate, sodium molybdate dihydrate, glycine N-bis(octylaminoethyl)hydrochloride and polyvinyl imidazol, adding the mixture into a ball mill, performing ball milling for 2-3 hours, and drying to obtain a flame retardant; and (2)uniformly mixing polypropylene resin, the flame retardant, N-acetylthiourea and mixed additives, adding the mixture into an extruder, performing melt spinning, braiding into a suspender and base clothby a weaving machine, cutting, and sewing, thereby obtaining the flame-retardant flexible freight bag. The preparation method of the flame-retardant flexible freight bag provided by the invention issimple to operate and low in cost, and the prepared flame-retardant flexible freight bag has excellent mechanical property and high filament strength, does not cause a breakage phenomenon after braided molding, particularly has excellent flame-retardant property, and can prevent fostering of the fire when the fire happens.

Description

technical field [0001] The invention belongs to the technical field of container bag preparation, and in particular relates to a method for preparing a flame-retardant container bag. Background technique [0002] Container bag, also called ton bag, is a flexible large packaging container, the main material is polypropylene, with dustproof, moisture-proof, radiation-resistant, safe, anti-aging, anti-ultraviolet, anti-static, dust-proof, dust-proof and gas-proof Explosive and other characteristics. Strong structure, suitable for modern large-scale transportation, very suitable for export, widely used in lithium powder lithium ore, silicon powder silicon ore, battery materials, zinc oxide powder, fluorite powder, copper oxide powder, tin oxide powder, lead oxide powder, titanium White, as well as the packaging of food-grade raw materials and auxiliary additives such as activated carbon, with a load capacity of 200kg-2000kg, which can be divided into round and square. It can b...
