Abstract

The invention discloses a flame-retardant type fuel plastic woven bag and a preparation method thereof. The flame-retardant type fuel plastic woven bag comprises the following raw materials in parts by weight: 100 parts of polypropylene granules, 170-180 parts of nano calcium carbonate powder, 4-5 parts of paraffin, 3-4 parts of stearic acid, 3.5-4.5 parts of a coupling agent, 0.2-0.6 part of an antioxidant DLTP, 9-11 parts of polyoxymethylene, 20-24 parts of linear low-density polyethylene, 1.3-1.6 parts of polyethylene wax, 3.1-3.6 parts of an ethylene-methyl acrylate copolymer, 1.3-1.7 parts of tributyl citrate and 0.5-0.9 part of turpentine. Abnormities such as adhesion and melt marks are avoided after the flame-retardant type fuel plastic woven bag is tested under high temperature of 85 DEG C, and the flame retardancy meets the standard of the coal industry, so that the flame-retardant type fuel plastic woven bag can be widely applied to packaging of chemical engineering products, industrial minerals, chemical fertilizers, cement, fish meal, grains, feeds, fruits, vegetables and other agricultural and sideline products.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to a flame-retardant plastic woven bag and a preparation method thereof. Background technique [0002] Ordinary polypropylene woven bag raw materials are blended with polypropylene base material and inorganic fillers such as calcium carbonate. Due to the poor compatibility between polypropylene base material and inorganic fillers, the amount of inorganic fillers is less, resulting in The softening temperature of the raw material is low, so it can only be used for packaging of materials below 100 °C. The flame-retardant plastic woven bags currently on the market are basically anti-aging types, that is, to prevent plastics from continuing to produce thermal oxygen aging at high temperatures, thereby prolonging the service life of plastic products, but they cannot improve the temperature resistance of woven bags. Contents of the invention [0003] In view of this, the object of ...
