Embodiment 1

[0027] Example 1 Add different proportions of TIPRPG to polyester PET, mix evenly, use XJ-01 type extruder to extrude a sample with a diameter of about 3 mm at melting temperature, and use HC900-2 type oxygen index tester to measure its limit Oxygen index, the results are shown in Table 2.

[0029]

Embodiment 2

[0030] Example 2 Add different proportions of TIPRPG and MCA to polyester PET, mix evenly, use XJ-01 type extruder to extrude a sample with a diameter of about 3mm at melting temperature, and use HC900-2 type oxygen index tester to measure The limiting oxygen index, the results are shown in Table 3.

[0031] Table 3 Flame retardant properties of flame retardants TIPRPG and MCA compounded on PET

[0032]

[0033] It can be seen from Table 3 that when 12 parts of TIPRPG and 8 parts of MCA are used in combination, the limiting oxygen index is increased by 3 compared with that of TIPRPG alone, reaching 30, which has a good synergistic effect of flame retardancy. And MCA is cheaper, which can reduce the cost.

Embodiment 3

[0034] Example 3 Add different proportions of TIPRPG and MPP to polyester PET, mix evenly, use XJ-01 type extruder to extrude a sample with a diameter of about 3mm at melting temperature, and use HC900-2 type oxygen index tester to measure The limiting oxygen index, the results are shown in Table 4.

[0035] Table 4 Flame retardant properties of flame retardants TIPRPG and MPP compounded on PET

[0036]

[0037] It can be seen from Table 4 that when 12 parts of TIPRPG and 8 parts of MPP are used in combination, the limiting oxygen index is increased by 2 compared with that of TIPRPG alone, reaching 29, which has a good synergistic flame retardant effect.

Abstract

The invention relates to a tetra(0-isopropyl-phenylphosphinyl)glycoluril (TIPRPG) flame retardant composition. The flame retardant composition is prepared from tetra(0-isopropyl-phenylphosphinyl)glycoluril and any one or two or three of melamine cyanurate (MCA), melamine polyphosphate (MPP) and diethyl aluminum phosphinate (1240) through compounding according to any weight ratio and uniformly mixing, wherein the weight fraction of TIPRPG in the flame retardant composition is greater than 0. The flame retardant composition disclosed by the invention has the advantages that multiple elements are synergic, the material compatibility is good, the flame retardance is high, the flame retardant composition is halogen-free and environment-friendly, the application cost can be reduced and the like, so that the flame retardant composition can be applied to flame retardants of polyester, polyamide and the like.

Description

technical field [0001] The invention relates to a tetrakis(0-isopropyl-phenylphosphinoyl) glycoluril flame retardant composition and an application method thereof, and the flame retardant composition can be used for flame retardancy of engineering plastics such as polyester and polyamide . Background technique [0002] Polyester has developed rapidly as a chemical fiber industry and engineering plastics industry. At present, my country's polyester production capacity ranks first in the world. At the same time, my country is also the world's largest polyester consumer market, but the flame retardant modification of polyester is less. At present, the flame retardant modification rate of polyester in my country is about 1%, while that in developed countries is 10-15%. There is great room for development of polyester flame retardant modification. At present, flame retardants for polyester generally have the disadvantages of high price and poor performance. It is an important ...
