Abstract

The invention discloses a polypropylene sphere bubble material and a preparation method thereof, wherein the polypropylene sphere bubble material is prepared from the following raw materials by weight: 98.225% of polypropylene, 0.1-0.3% of a transparent nucleating agent, 0.1-0.3% of a rigidity increasing nucleating agent, 0.3-1% of an organic diffusing dispersant, 0.01-0.03% of a fluorescent whitening agent, 0.05% of N,N'-ethylenebis(stearamide), 0.05-0.4% of an antioxidant 1010, 0.1-0.3% of an antioxidant 168, 0.2-0.6% of an ultraviolet ray absorber Uv-531, and 0.03% of white expansion oil. According to the present invention, the polypropylene raw material and various auxiliary agents are mixed by using the high speed stirrer, and the obtained mixture is subjected to melt extrusion and granulation with the twin-screw granulation machine; the prepared polypropylene sphere bubble material has advantages of excellent mechanical property, high transparency and light stability; the method has advantages of short product molding cycle, rapid processing, production efficiency improving, and manufacturing cost reducing; and the obtained polypropylene sphere bubble material is specially applied in LED lampshades and other lamp tool members.

Description

technical field [0001] The invention relates to a novel modified polypropylene material, in particular to a polypropylene bulb material used in the field of LED lamp shades and a preparation method thereof. Background technique [0002] The materials required for the LED lampshade in the prior art are the following two types. [0003] Polycarbonate (referred to as PC) is an amorphous thermoplastic resin with excellent comprehensive properties containing carbonate groups in its molecular chain. It has excellent electrical insulation, elongation, dimensional stability, good heat resistance, and low water absorption. , non-toxic and excellent impact performance, due to the special structure of polycarbonate, it has become the fastest growing general-purpose engineering plastic among the five major engineering plastics, however, unmodified polycarbonate still has shortcomings , which is specifically manifested in insufficient processing fluidity, easy stress cracking, poor chem...
