In the application, because the particle diameter of fast extruding furnace black and high abrasion furnace black is smaller, it is nanoscale, is not easy to disperse, therefore
The beautiful powder of silicon is further added in reinforcing filler, the dispersiveness and mobility of reinforcing agent can be improved, is advantageous to improve extrusion
Performance.
Preferably, the plasticizer is paraffin oil.
Preferably, the trifunctional group acrylate is trimethylol-propane trimethacrylate.
Vulcanizing agent employs cumyl peroxide and sulphur in the application, and uses trifunctional group acrylate and poly- fourth
For diene resin as crosslinking coagent, the addition of sulphur can extend time of scorch, while can deepen state of cure (vulcanization)；Trifunctional
Acrylate and polybutadiene add as crosslinking coagent, are favorably improved the resistance to elevated temperatures of material, can reduce material
The high temperature compression of material, while the adhesive force and bonding force of material and line, material and material can be increased, improve the quick-fried of pipe
Broken pressure.
Antiscorching agent is employed in the application, extends time of scorch, is advantageous to extrude.
Age resistor is simultaneously using 4,4- double (α, α dimethyl benzyl) diphenylamines, 2,2,4- trimethyls -1,2- two in the application
Hydrogenated quinoline condensate and 2-mercaptobenzimidazole, wherein 4,4- double (α, α dimethyl benzyl) diphenylamines are that a kind of high temperature is anti-old
Agent, inventor have found that with after other component combines, having good synergy, resulting composition resists age resistor of the present invention
The performances such as aging are more preferable.
Supporting material is use only in the application, not using dis-reinforcing filler, to meet urea conducting tube high rigidity 75
± 5HA and high tensile >=14MP requirement, while meet the requirement of low high temperature compression.After being combined with other components,
The application can take into account the processing characteristics of material simultaneously.
The urea conducting tube of the application exploitation is requirement without metals such as zinc, copper, magnesium, and requires 150 DEG C of high temperature resistant, low
High temperature compression≤25%, and can be separated out after zinc, copper, magnesium contact urea, and then produce corrosion.
The application further relates to a kind of preparation method of automobile using urea conducting tube pipeline elastomeric material, comprises the following steps：
