Abstract

The invention discloses a high-flow, high-modulus, flame-retarding polypropylene composite material for an LFT-D production process. The composite material is composed of following components, by weight, 70-90 parts of polypropylene, 3-10 parts of a compatilizer, 0-0.5 parts of a lubricant, 0-5 parts of an anti-glass fiber exposure agent, 0.1-0.5 parts of an antioxidant, 0-0.5 parts of a photo-stabilizer, 5-25 parts of a flame retardant and 0-5 parts of other additives. The polypropylene composite material has high flowability and modulus and is suitable for a full-automatic LFT-D production process. A product can have a complex structure, is large in breadth and has good size stability.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a high-flow, high-modulus, flame-retardant polypropylene composite material used in the LFT-D production process. technical background [0002] Long fiber reinforced thermoplastics (LFT for short) is a kind of thermoplastic composite material, and it is also a hot spot in the development of thermoplastic composite materials abroad. The material has the characteristics of light weight, high strength, environmental protection and recyclability, and is widely used in the automotive industry, such as used to make structural and semi-structural components, such as front-end modules, bumper beams, instrument panel skeletons, battery brackets, spare tire compartments, Seat frames, pedals, and overall floor panels are ideal materials for lightweight vehicles. The LFT-D production line is also the online composite molding production line for long fiber r...
