Problems solved by technology

As we all know, during the process of air circulation in the air duct, there will be some dust and moisture attached to the air duct inside the car, which is conducive to the growth of microorganisms and bacteria. When the air circulates again, the air will take away the bacteria in the air duct and spread them into the car. , have an impact on the health of passengers

Abstract

The invention provides an XPE air duct for an automobile and a preparation method of the XPE air duct. The XPE air pipe is prepared from the following raw materials in parts by weight: 50-100 parts of polyethylene, 10-35 parts of a foaming agent, 8-20 parts of modified zinc oxide, 1-10 parts of calcium stearate, 2-8 parts of a cross-linking agent, 0.5-1.5 parts of a coupling agent and 0.3-1.6 parts of an antibacterial agent, the antibacterial agent comprises a combination of a nano silver antibacterial agent and a nano zinc oxide antibacterial agent. The XPE air pipe provided by the invention not only has the characteristic of light weight, but also has better antibacterial and mildew-inhibiting properties.

Description

technical field [0001] The invention belongs to the technical field of automobile air ducts, and in particular relates to an XPE air duct for automobiles and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people are paying more and more attention to the level of air quality in cars. Not only pay attention to the health and environmental protection of vehicle interior materials, but also pay more and more attention to the high quality of automotive air-conditioning ducts. The air duct of the car is connected to the air conditioning outlet and the air outlet. It is the air duct for cooling and heating air in the air conditioning system. It is responsible for sending the processed temperature adjustment, humidity adjustment, and purified airflow to the cockpit to complete the ventilation in the cockpit. , Cooling, heating, defrosting and defogging functions. Therefore, the preparation of automobile air ducts has ...
