Low-emission glass fiber reinforced polypropylene composite material and preparation method thereof

The invention provides a low-emission glass fiber reinforced polypropylene composite material and a preparation method thereof. The preparation method comprises the following steps of: obtaining raw material polypropylene resin, glass fiber, compatibilizer and auxiliary agents, blending the polypropylene resin, the compatilizer and the auxiliary agents to obtain a mixture; feeding the mixture andthe glass fibers to an extruder and melt-extruding under microwave conditions. In that preparation of the composite material, the microwave is introduced into the preparation of the composite material, the heat can be ensured to penetrate into the interior of the polypropylene macromolecule and the additive molecule, the excessive overheating caused by partial overheating is avoided, thereby effectively reducing the amount of the polypropylene or the additive decomposed into the volatile organic small molecular compound when the glass fiber reinforced polypropylene composite material is produced, and obviously reducin
