Abstract

The invention discloses a metering oil pipe for petrochemical industry and a preparation method thereof. The oil metering pipe for petrochemical industry comprises a composite barrier layer, a first antistatic plastic layer, a fiber-reinforced explosion-proof layer and a second antistatic The plastic layer, wherein the composite barrier layer is composed of a low-permeability barrier layer distributed inside and outside, a reinforced barrier layer and an adhesive layer between the two. The above metering oil pipe for petrochemical industry not only greatly improves the overall barrier performance and environmental protection performance through the internal and external cooperation of multiple layers of different materials, but also has excellent antistatic performance and comprehensive mechanical properties, such as bending resistance, anti Tensile, compressive, anti-explosion and other properties, can be widely used in the field of oil delivery and transportation, automotive fuel systems, etc.

Description

technical field [0001] The invention relates to an oil pipe for petrochemical industry, in particular to a metering oil pipe for petrochemical industry and a preparation method thereof. Background technique [0002] With the enhancement of people's awareness of environmental protection and the strict implementation of environmental protection laws, environmental protection has covered the prevention and control of air, water, soil, noise and other aspects. Especially the air pollution, whether it is particulate matter such as PM2.5, nitrogen oxides, hydrocarbons, or carbon monoxide, will increase with the increase of sulfur content. Fuel oil pollution is an important source of pollution, which has received more and more attention. [0003] Fuel pollution comes from two aspects. On the one hand, the sulfur content in fuel oil is an important source of air pollution; on the other hand, the leakage and volatilization of fuel oil are also important reasons for the increase of ...
