Abstract

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.

Description

technical field [0001] The invention relates to the field of materials, in particular to an easy-to-clean and spray-free polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) has the advantages of non-toxicity, low odor, low cost, chemical corrosion resistance, good mechanical properties, etc. It has a very wide range of applications in the fields of home appliances, sanitary ware, and electronics. In recent years, with the development of spray-free materials, more and more parts have begun to use spray-free technology. Spray-free coating can not only save process steps and reduce costs, but also be environmentally friendly. [0003] However, in actual use, there are also many challenges in spray-free polypropylene materials. For example, the spray-free polypropylene materials used in the shells of electric rice cookers and electric pressure cookers, because they are in the kitchen environment for a long time, kitchen appl...
