[0036] After the above components are fully mixed in a high-speed mixer, they are extruded and granulated by a twin-screw extruder. The extrusion temperature is controlled at 180°C and the screw speed is controlled at 400r / min to obtain the product. The obtained products are subjected to relevant experi...

[0042] After the above components are fully mixed in a high-speed mixer, they are extruded and granulated by a twin-screw extruder. The extrusion temperature is controlled at 180°C and the screw speed is controlled at 400r / min to obtain the product. The obtained products are subjected to relevant experimental tests, the flexural strength and flexural modulus are tested according to GB / T9341, the notched impact is tested according to GB / T1843, the flame retardancy is tested according to ASTM UL94, and the glow wire ignition temperature is tested according to IEC60695.2-12 . The test results are shown in the table below:

Embodiment 5
[0044] Example 5 is a method of directly adding various flame retardants, and the added content is equivalent to 26% coated flame retardant masterbatch. Comparing Example 5 and Example 8, it can be seen that the method of adding masterbatches improves the flame retardant of the system. The ignition level has been increased from 3.2mmV-0 to 1.6mmV-0, and the glow wire ignition temperature has also been improved. Comparing Example 5 and Example 6, the amount of coating masterbatch added in Example 6 is only 22%, but the flame retardant performance of Example 6 has fully reached the effect of Example 5, indicating that the same flame retardant level coating masterbatch is achieved The use of pellets can reduce the amount of flame retardants.
