Abstract

The invention discloses a special material for flame-retardant plastic sheets for steel coil packaging. The raw materials of the special material comprise, by weight, 80 parts of PC / ABS, 1-2 parts ofa silane coupling agent, 2-4 parts of muscovite powder, 4-8 parts of a toughening agent, 15-20 parts of a plasticizer, 8-15 parts of a flame retardant, 0.3-0.5 part of an antioxidant, 0.2-0.5 part ofa lubricant, 0.1-0.3 part of nano-silica and 0.1-0.3 part of wollastonite powder. The invention also discloses a preparation method of the special material for flame-retardant plastic sheets for steelcoil packaging. The preparation method comprises the following steps: (1) uniformly mixing the PC / ABS, the silane coupling agent, the muscovite powder, the toughening agent, the plasticizer, the flame retardant, the antioxidant, the lubricant, nano-silica and the wollastonite powder; and (2) transferring the obtained mixture into a twin-screw extruder, and carrying out melt extrusion granulationmolding under a vacuum condition by the twin-screw extruder. The special material for the flame-retardant plastic steel sheets for steel coil packaging has good mechanical properties, and meets the using requirements of steel coil packaging materials.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a special flame-retardant plastic sheet material for steel coil packaging and a preparation method thereof. Background technique [0002] At present, a large number of wood fiberboards are used in steel coil packaging. Due to the growing gap between the amount of wood used and the growth rate of shrubs, the ecological balance is seriously damaged. However, plastic packaging is light, cheap, easy to pack, and has a simple molding process. More and more applications. Existing plastic packaging has disadvantages such as low tensile strength, poor impact resistance, and flammability. Contents of the invention [0003] The present invention aims to overcome one of the defects in the above-mentioned prior art, and provides a special flame-retardant plastic sheet material for steel coil packaging. The raw material composition includes: [0004] [0005] The flame reta...
