The invention relates to a glass fiber reinforced polypropylene material used for thin-wall injection molding. The glass fiber reinforced polypropylene material comprises the following components (inpercentages by mass): 41-47% of polypropylene resin, 4.5-8% of an amorphous polyolefin, 18-22% of modified glass fibers, 12.5-16.2% of a polyolefin elastomer, 7.7-11% of ternary copolymer polypropylene, 4-6% of styrene-butadiene transparent impact-resistant resin, 0.1-0.5% of a main antioxidant, and 0.3-0.8% of an auxiliary antioxidant, wherein the cross section of the glass fibers is elliptical.At the same time, the invention also relates to a method of preparing the material. The surface of a component prepared from the material provided by the invention has no floating fibers, low warpage,no gas mark and no tiger skin stripes, and the component has good mechanical properties; at the same time, the elliptical cross section of the glass fibers reduces orientation of the glass fibers andreduces anisotropy of the glass fibers, so that the problem of warpage deformation of the glass fiber reinforced polypropylene material is improved, and the mechanical properties of the material areimproved; and the glass fibers have better compatibility with the polypropylene material after being modified by hydrofluoric acid, the glass fibers and the polypropylene material are more tightly combined, so that the mechanical properties of the prepared finished product are improved.

The invention relates to a glass fiber enhanced flame retardant polypropylene composite material for an upper cover of a battery pack and a preparation method thereof. The composite material is prepared from the following raw materials in parts by weight: 18.4-58.7 parts of polypropylene, 20-40 parts of glass fibers, 20-30 parts of a flame retardant, 1-10 parts of an interface compatilizer, 0.2-0.6 part of a microstructure adjusting aid and 0.1-1 part of an antioxidant. The material is produced by a processing mode of preimpregnating a melt into continuous long fibers, so that the demand on performance of the material is met, and the problem that it is hard to process and low in yield in a high powder filling condition is solved. The original two-step method process method is simplified toone-step method processing, so that the processing course is simplified, the yield of the material is improved and the manufacturing cost is lowered.

The invention belongs to the field of polymer materials and provides a weather-resistant matte-type high-strength PA6 and ASA alloy material and a preparation method thereof. The PA6 and ASA alloy material comprises the following components: 40%-70% of PA6, 10%-25% of ASA, 10%-20% of carbon fiber, 8%-12% of nano-montmorillonite, 1%-5% of a compatibilizer, namely, ABS grafted maleic anhydride, 1%-5% of a toughener, namely, POE grafted maleic anhydride, 0.1%-1% of an antioxidant, 0.1%-1% of a lubricant and 1%-2.5% of carbon black. By adopting the PA6 and ASA alloys, an incompatible system of the PA6 and ASA alloys in a sea-island structure forms slightly rough surfaces of the surface and thus matte delustering-grade surface is formed, the nano-montmorillonite is added to further homogenize the distribution of the slightly rough surfaces and meanwhile, carbon fiber is added to achieve a reinforcement effect, the compatibilizer is added so that the phenomenon that two resins are severely separated and the material is layered and peeled are not caused, and carbon black is added such that the UV aging resistance of the material can be effectively improved, therefore, the weather-resistant matte-type high-strength PA6 and ASA alloy material disclosed by the invention is a matte-grade interior/exterior material which has very excellent overall performance.
