The invention provides an easy-to-clean spraying-free
polypropylene material and a preparation method thereof. The easy-to-clean spraying-free
polypropylene material is prepared from the following rawmaterials in parts by weight: 70-90 parts of low-
viscosity polypropylene resin, 10 to 30 parts of high-
viscosity polypropylene resin, wherein the weight parts of the low-
viscosity polypropylene resinand the weight parts of the high-viscosity polypropylene resin sum to 100 parts, 0.5 to 1 part of an
antioxidant, 0.5 to 1 part of a lubricating agent and 1-5 parts of easy-to-clean
metal toner master batch. The preparation method comprises the following steps: mixing the low-viscosity polypropylene resin, the high-viscosity polypropylene resin, the
antioxidant and the
lubricant by using a high-speed
agitator, and adding the obtained mixture into a double-screw extruder through a main feeding port; adding the easy-to-clean
metal toner master batch into the double-screw extruder through a sidefeeding port; and then performing
melt extrusion and
granulation to obtain the material. The easy-to-clean spraying-free polypropylene material has excellent mechanical properties, processability andeasiness in cleaning, and can be applied to the fields of automobiles and household appliances such as automobile exterior trim, air conditioner decoration strips, exterior decoration structures of small household appliances and the like.
