Abstract

The invention discloses a flame-retardant glass fiber reinforced polypropylene composite material for manufacturing a coil frame and a preparation method thereof. The composite material is mainly prepared from polypropylene, glass fiber, a fire retardant, a compatilizer, a nucleating agent, a dispersing agent and an antioxidant serving as raw materials. The preparation method comprises the following steps of: (1) uniformly mixing the polypropylene, the fire retardant, the compatilizer, the nucleating agent, the dispersing agent and the antioxidant; and (2) performing melt extrusion on the mixed raw materials obtained by the step (1) and the glass fiber in a melt extruder and pelleting to obtain a product. The invention provides the flame-retardant glass fiber reinforced polypropylene composite material for manufacturing the coil frame and the preparation method thereof.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a modified composite material and a preparation method thereof, in particular to a flame-retardant glass fiber-reinforced polypropylene composite material for manufacturing a coil skeleton and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a general-purpose plastic widely used in various electronic and electrical components. [0003] The most prominent property of polypropylene is its multi-facetedness. Its value and multi-facetedness mainly come from its excellent chemical resistance. Common acid and alkali organic solvents have little effect on it. It has a relatively low Density and relatively high melting point. In addition, polypropylene (PP) is non-toxic, tasteless, low density, has good electrical properties and high-frequency insulation, and is not affected by humidity. It is suitable for making mechanical parts, corrosion-resist...
