Abstract

The invention discloses a flame retardation fiber reinforced polyethylene flexible coil and a manufacturing method thereof. The manufacturing method comprises the following steps: bleaching wood fibers by using a degreasing and bleaching solution, and uniformly mixing the degreased and bleached wood fibers, high-polymerization degree ammonium polyphosphate, light calcium carbonate, a silane coupling agent A-172, chlorinated paraffin, dicapryl phthalate and stearic acid in a high speed mixer to obtain a premix; spraying atomized melamine resin to the premix while stirring in order to coat the premix; drying the coated premix, and uniformly mixing the dried melamine resin coated premix with linear low-density polyethylene resin to obtain a mixture; and sequentially carrying out kneading extrusion, open milling tabletting, press polishing lamination, molding cooling fixing and cutting trimming on the mixture to obtain the flame retardation fiber reinforced polyethylene flexible coil. The flame retardation fiber reinforced polyethylene flexible coil has the advantages of goof flame retardation and fireproofing performances, large strength and good flexibility.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite materials, and in particular relates to a flame-retardant wood fiber reinforced polyethylene flexible coil and a manufacturing method thereof. Background technique [0002] Polyethylene (PE for short) is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100 ° C ~ -70 ° C), good chemical stability, and can withstand most acid and alkali erosion. Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. [0003] Wood fiber has relatively high strength and rigidity and low density. It is added to plastics such as polyvinyl chloride, polyethylene, polypropylene, ABS resin and polystyrene to make wood-plastic composite materials. It has filling, strengthening, Reduce weight and cost. [000...
