Problems solved by technology

However, the existing automobile air ducts are poor in flame retardancy, which brings hidden dangers to the safety of passengers; the environmental protection is not up to standard, especially the smell, which affects the physical and mental health of passengers-the current air ducts are mainly blow molding processes, and the materials used are usually PE, and it is difficult for PE materials to meet the flame retardancy and smell requirements at the same time

Abstract

The invention provides an automobile air duct and a preparation method thereof, the automobile air duct comprises the following raw materials in parts by weight: 70-82 parts of PE (polyethylene), 4-8parts of antimonous oxide, 8-16 parts of decabromodiphenyl ethane, 3-10 parts of POE, 0.1-0.3 part of antioxidant 1076, 0.1-0.3 part of antioxidant 168 and 0.1-0.4 part of ultraviolet absorbent UV 944; and an anti-dripping agent accounts for 0.35% of the total weight of the substances. The automobile air duct is formed by blow molding, and the prepared automobile air duct is good in flame retardancy, high in anti-bending strength, high in tensile strength and small in smell.

Description

technical field [0001] The invention relates to an automobile air duct and a preparation method thereof. Background technique [0002] Cars have become a common tool for people to travel. High speed, comfort and safety are people's pursuit of cars. Cars are better sealed. For comfort, the requirements for odor in the car are relatively high. In order to improve the safety performance of cars, Auto parts are required to have good flame retardancy. However, the existing automobile air ducts are poor in flame retardancy, which brings hidden dangers to the safety of passengers; the environmental protection is not up to standard, especially the smell, which affects the physical and mental health of passengers-the current air ducts are mainly blow molding processes, and the materials used are usually PE, and it is difficult for PE materials to meet the flame retardancy and odor requirements at the same time. Contents of the invention [0003] In order to solve the above proble...
