Background technology
Along with industrial expansion, electric wire demand increases day by day, and for electric wire
Insulating sheath material belongs to organic polymer mostly, and this kind of electric wire is at high pressure, thermal source, certain
Burning is easily caused under the conditions of temperature, oxygen concentration etc..So the fire-retardant of cable material of polyolefin seems
The most necessary, halogen containing flame-retardant flame retarding efficiency is high, but when fire occurs, Halogen fire proofing
A large amount of toxic gas can be discharged, the mankind, environment are caused " secondary harm ".Therefore, along with
People's requirement to environmental protection, developing novel, phosphorus flame retardant etc. is that cable material grinds
Study carefully the focus in field.
At present, EVA/MH is the study hotspot of non-halogen flame-retardant cable, but due to magnesium hydroxide
How the shortcoming of fire retardant self, can guarantee that again while reducing flame retardant of magnesium hydroxide consumption
System possesses good anti-flammability and is always study hotspot.

(> 99.9%, Germany's Lay is because stepping on chemical industry in Fil) 8 kilograms and N-(cyano methyl)-4-(2-((4-(4-(2-
Oxo-pyrrolidine-1-base) piperidin-1-yl) phenyl) amino) pyrimidine-4-yl) Benzoylamide 3 kilograms；
Adding distilled water in magnesium hydroxide makes magnesium hydroxide quality % in magnesium hydroxide slurry be 7
Weight %, is subsequently adding N-(cyano methyl)-4-(2-((4-(4-(2-oxo-pyrrolidine-1-base) piperidines
-1-base) phenyl) amino) pyrimidine-4-yl) Benzoylamide, it is placed in thermostat water bath heating together,
Limit heating edge is stirred by high shearing mixing emulsor, and rotating speed is 500 turns/min, when temperature exists
When 60 DEG C, add EVA, di-n-octyl sebacate, polypropylene grafted maleic anhydride, 2,4,6-tri-
Tert-butyl phenol, stirs 3 minutes at 1000 turns/min, mix homogeneously, is heated to 110 DEG C of temperature,
Putting in screw extruder and extrude and get final product, wherein extrusion temperature is 220 DEG C, in extrusion
Steam pressure controls as 1Mpa.
Embodiment 2
Prepare halogen-free anti-flaming polyolefin power cable according to the same manner as in Example 1, different
Part is not use N-(cyano methyl)-4-(2-((4-(4-(2-oxo-pyrrolidine-1-base) piperidines-1-
