Problems solved by technology

Therefore, automotive bellows require high toughness and flame retardancy. This is because the wall of the automotive bellows is thin and belongs to thin-walled pipes. If the toughness is too low, it will affect the springback of the bellows opening after being stressed, and affect the service life of the bellows.

Abstract

The invention discloses a flame-retardant and anti-aging polypropylene material for automobile corrugated pipes and a preparation method thereof, wherein the polypropylene material is formed by mixingand extrusion granulation of polypropylene, a flame retardant, a flame retardant synergist, a toughening agent, a lubricant, a light stabilizer, a dispersant and an antioxidant. By using the flame retardant, the compound anti-aging auxiliary agent and the high-efficiency dispersant, the polypropylene masterbatch is endowed with high anti-aging performance, at the same time, the flame retardant level can reach V-0, and corresponding automobile corrugated pipe materials can be provided according to the flame retardant requirements of different customers.

Description

technical field [0001] The invention belongs to the technical field of polypropylene materials, and in particular relates to a flame-retardant and anti-aging polypropylene material for automobile bellows and a preparation method thereof. Background technique [0002] As corrugated pipes are widely used in machinery manufacturing, petrochemical and various construction projects, they have expanded to more fields in recent years. With the promotion of lightweight, and because of the material cost, production cost and excellent performance of polypropylene, polypropylene automotive bellows have great development prospects in the future market. Bellows are generally soft connections on hard pipes to slow down the vibration and deformation of pipes. Automotive bellows are used to reduce vibration and noise, facilitate installation and prolong the life of the exhaust muffler system. They are used to absorb the vibration of the exhaust system. Prevent excessive thermal deformation...
