Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high flame-retardant, high-rigidity and easy-to-process glass fiber reinforced flame-retardant polypropylene composite material for the upper cover of a battery pack and a preparation method thereof. Background technique [0002] At present, with the enhancement of environmental protection awareness in various countries, the market share of new energy vehicles has gradually increased, and the demand for materials around new energy vehicles in the material market has gradually increased. Compared with traditional fuel vehicle materials, new energy vehicle battery peripheral materials are a new market in the material market. Due to the particularity of the battery part of the new energy vehicle, the battery pack design has extremely high safety requirements for this part, so the materials used in the battery part, whether it is a structural part material or ...
