Embodiment 1
[0036] The halogen-free flame-retardant polypropylene compound of this embodiment is composed of the components in Table 1 (Example 1), and the preparation method of the halogen-free flame-retardant polypropylene compound is as follows:
[0037] (1) Mix 0.5 parts by weight of hindered amine light stabilizer UV-3529, 1 part by weight of epoxy resin KD-213, 10 parts by weight of intumescent halogen-free flame retardant FP-2200 and 10 parts by weight of polypropylene PP S700 in banburying Fully banbury in the machine for 30 minutes to ensure that the surface of the halogen-free flame retardant is fully coated with epoxy resin and hindered amine light stabilizer, so as to improve the thermal stability and hydrolysis resistance of the halogen-free flame retardant. A single-screw extruder connected in series with an internal mixer is extruded and granulated to obtain flame-retardant masterbatches.
[0038] (2) Combine the flame retardant masterbatch produced by the first step intern...
Embodiment 2
[0040] The halogen-free flame-retardant polypropylene compound of this embodiment is composed of the components in Table 1 (Example 2), and the preparation method of the halogen-free flame-retardant polypropylene compound is as follows:
[0041](1) 1 part by weight of hindered amine light stabilizer UV-3529, 2 parts by weight of epoxy resin KD-213, 20 parts by weight of intumescent halogen-free flame retardant FP-2200 and 5 parts by weight of polypropylene PP S700 in banburying Fully banbury in the machine for 30 minutes to ensure that the surface of the halogen-free flame retardant is fully coated with epoxy resin and hindered amine light stabilizer, so as to improve the thermal stability and hydrolysis resistance of the halogen-free flame retardant. A single-screw extruder connected in series with an internal mixer is extruded and granulated to obtain flame-retardant masterbatches.
[0042] (2) The flame retardant masterbatch produced by the first step internal mixer interna...
Embodiment 3
[0044] The halogen-free flame-retardant polypropylene compound of this embodiment is composed of the components in Table 1 (Example 3), and the preparation method of the halogen-free flame-retardant polypropylene compound is as follows:
[0045] (1) 2 parts by weight of hindered amine light stabilizer UV-3529, 4 parts by weight of epoxy resin KD-213, 30 parts by weight of intumescent halogen-free flame retardant FP-2200 and 15 parts by weight of polypropylene PP S700 in banburying Fully banbury in the machine for 30 minutes to ensure that the surface of the halogen-free flame retardant is fully coated with epoxy resin and hindered amine light stabilizer, so as to improve the thermal stability and hydrolysis resistance of the halogen-free flame retardant. A single-screw extruder connected in series with an internal mixer is extruded and granulated to obtain flame-retardant masterbatches.
[0046] (2) The flame-retardant masterbatch produced by the first step of internal mixer m...
