Abstract

The invention belongs to the field of polypropylene composites, and discloses a black glass fiber reinforced polypropylene composite and a preparation method and application of the black glass fiber reinforced polypropylene composite. The black glass fiber reinforced polypropylene composite comprises the flowing components, by mass, 50.4-86.7% of polypropylene, 10-40% of glass fibers, 2-6% of compatilizer, 0.4-1.0% of carbon black, 0.2-0.8% of primary antioxidants, 0.2-0.8% of auxiliary antioxidants and 0.5-1% of other auxiliaries, and the carbon black is furnace carbon black with the 45-145mg / g iodine absorption value. Because the furnace carbon black with the proper iodine absorption value is added to the black glass fiber reinforced polypropylene composite, the adverse effect of the furnace carbon black on the hot oxygen aging resisting performance of the polypropylene composite is reduced, the antioxidant content in the polypropylene composite is reduced and the hot oxygen aging resisting performance of the black glass fiber reinforced polypropylene composite is improved. The black glass fiber reinforced polypropylene composite keeps good dispersity and pigmentation degree and meanwhile reduces the using amount of the antioxidants and product cost.

Description

technical field [0001] The invention belongs to the field of polypropylene composite materials, in particular to a black glass fiber reinforced polypropylene composite material and its preparation method and application. Background technique [0002] In recent years, with the rapid development of the automobile industry, the demand for black glass fiber reinforced polypropylene composite materials is increasing. However, in many cases, polypropylene is required to have a certain heat and oxygen aging resistance. For example, modified polypropylene as an automotive interior material generally requires an aging time of 400 hours or more at 150°C. If it is a PP material near the engine compartment, then The requirements are higher, usually requiring more than or equal to 1000 hours. There are tertiary carbon atoms in the main chain of polypropylene (PP), which are prone to chemical changes under the action of external factors such as heat, oxygen, and ultraviolet rays.
