Problems solved by technology

When the transmission and distribution of the pipeline network is too long, it is vulnerable to the threat of irresistible natural disasters and the damage of broken roads, roads, external forces and other conditions, resulting in extremely unstable and unsafe factors
The main reason is that the cooker leaks or the pipe connection hose is aging, deformed, or falling off.
At present, the use of unqualified plastic hoses and stoves without flameout protection devices is quite common for gas users, especially in winter when the doors and windows are closed, which poses a high risk of gas safety hazards and explosion risks
In the traditional gas transmission and distribution design, metal materials such as steel pipes and cast iron pipes have always been used. However, metal gas pipelines have disadvantages such as poor corrosion resistance, inconvenient transportation and installation, and high production and installation costs. The existing technology and There are also few loose pipe materials dedicated to low-hydrocarbon dyes on the market, and those skilled in the art urgently need to develop a preparation method for light-hydrocarbon fuel rubber hoses

Abstract

The invention discloses a preparation method of a light hydrocarbon fuel rubber hose, and belongs to the technical field of high polymer materials. The light hydrocarbon fuel rubber hose adopts reactive extrusion, has the characteristics of no blockage and stiffness, excellent flexibility, can work in complex and harsh industrial working environments, and has elasticity, frost resistance, wear resistance, tear resistance, dilution acid resistance, low temperature water resistance and alcohol resistance, and compared with the prior rubber light hydrocarbon fuel pipeline, the overall performances of the light hydrocarbon fuel rubber hose, especially the advantages of no air leakage, wear resistance, corrosion resistance, antistatic property, small wind resistance, strong compressive strengthand the like, are superior to that of common hard pipelines, and the light hydrocarbon fuel rubber hose is safe and reliable, convenient to install and disassemble, saves time and labor, resists corrosion, is free of maintenance, and has long service life.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a preparation method of a light hydrocarbon fuel rubber hose. Background technique [0002] Light hydrocarbon gas is a new type of environmentally friendly liquid fuel. It uses the by-products C5 and C6 in the process of oil and natural gas mining and processing as raw materials for gas production. Through the patented technology product "light hydrocarbon gas generator", it adopts physical gasification , to convert liquid light hydrocarbons into gaseous mixed gas, which is transported to end users through pipelines. Like natural gas, light hydrocarbon gas is a clean fuel. In addition to high calorific value and clean combustion emission, compared with natural gas and liquefied petroleum gas, its transportation, storage and distribution are more convenient and safe. It is an ideal air source for cooking, heating, cooling and production heating facilities of public uti...
