(2) raw material being stirred is added to twin screw extruder, add glass fibre to twin screw extruder again, temperature in twin screw extruder is respectively: 255 DEG C of district's temperature, 255 DEG C of two district's temperature, 255 DEG C of three district's temperature, 250 DEG C of four district's temperature, 250 DEG C of five district's temperature, 245 DEG C of six district's temperature, 240 DEG C of seven district's temperature, 240 DEG C of eight district's temperature, die head temperature is 250 DEG C, vacuum pressure >=0.08pa, after discharging, tie rod is crossed water cooling, pelletizing, dry, packaging.
The advantages such as brominated Polystyrene has high flame retardant, thermostability and good electrical property, and dispersiveness and compatibility are good in superpolymer, is easy to processing, non-blooming, its good electrical property can improve the CTI value of this nylon.
Glass fibre has good thermotolerance and higher physical strength, can increase accordingly resistance toheat and the intensity of this nylon.
Zinc borate has high thermal stability, can effectively improve the flame retardant properties of nylon, and the feature such as nontoxic, low water solubility, granularity is little, proportion is little, good dispersity, and environmental protection easily processing again, has reduced the injury to processing staff greatly.
Antioxidant 1010 is a kind of hindered phenol antioxygen of high molecular, and volatility is very low, and is difficult for migration, and resistance to extraction, can improve the antioxygen property of this nylon, can effectively extend the work-ing life of goods; Antioxidant 1010 is also a kind of processing stabilizers efficiently simultaneously, can improve the discoloration-resistant of polymer materials under high temperature process condition.
Oxidation inhibitor 1068 is composite products of antioxidant 1010 and irgasfos 168, and compound oxidation inhibitor 1068 has lower cost, better than the antioxidant effect of independent use irgasfos 168 or antioxidant 1010.
Calcium stearate can increase the workability of this nylon in the time of extrusion moulding and compression moulding, makes nylon molding more laborsaving, greatly reduces production difficulty, has improved production efficiency.
There are good synergistic effect antimonous oxide and above-mentioned brominated Polystyrene used time, and flame retardant effect obviously improves.Improve greatly the flame retardant properties of this nylon.
Halogen-free flame retardants synergist is mainly taking nitrogen system, phosphorus series compound and metal hydroxides as main, non-volatile when burning, do not produce corrosive gases, safety and environmental protection, and it can coordinate with other fire retardant, coordinate performance, has improved again CTI value when improving flame retardant resistance.
The invention has the beneficial effects as follows: brominated Polystyrene and zinc borate all have high flame retardant, thermostability and electrical property, can improve flame retardant resistance and the CTI value of this nylon, add antimonous oxide to play synergistic effect with brominated Polystyrene simultaneously, obviously improve the flame retardant properties of this nylon, halogen-free flame retardants synergist can coordinate with other fire retardant, play coordinative role, make this nylon there is excellent flame retardant properties and higher CTI value.
