Embodiment 1

[0028] Example 1 Add different proportions of TEG into polyester PET, mix evenly, extrude a spline with a diameter of about 3mm with an XJ-01 extruder at the melting temperature, and measure its limit with a HC900-2 oxygen index tester Oxygen index, the results are shown in Table 2.

[0029] Table 2 Flame retardant properties of flame retardant TEG on PET

[0030]

Embodiment 2

[0031] Example 2 Adding different proportions of TEG and MCA to polyester PET, mixing uniformly, extruding a spline with a diameter of about 3 mm with an XJ-01 extruder at the melting temperature, and measuring it with a HC900-2 oxygen index tester. Its limiting oxygen index, the results are shown in Table 3.

[0032] Table 3 Flame retardant properties of flame retardant TEG and MCA compounded to PET

[0033]

[0034] It can be seen from Table 3 that when 12 parts of TEG and 8 parts of MCA are used in combination, the limiting oxygen index is 2 higher than that of TEG alone, reaching 31, which has a good flame retardant synergistic effect. And MCA is cheaper and can reduce costs.

Embodiment 3

[0035] Example 3 Different proportions of TEG and MPP were added to polyester PET, mixed uniformly, and a spline with a diameter of about 3 mm was extruded with an XJ-01 extruder at the melting temperature. Its limiting oxygen index, the results are shown in Table 4.

[0036] Table 4 Flame retardant properties of flame retardant TEG and MPP compounded to PET

[0037]

[0038] It can be seen from Table 4 that when 12 parts of TEG and 8 parts of MPP are used in combination, the limiting oxygen index is increased by 1 to 30 when TEG is used alone, which has a good synergistic flame retardant effect.

Abstract

The invention relates to a 4(0,0-diethyl phosphoryl)glycoluril flame retardant composition. The flame retardant composition is prepared by compounding and uniformly mixing 4(0,0-diethyl phosphoryl)glycoluril (TEG) with any one, two or three of melamine cyanurate (MCA), melamine pyrophosphate (MPP) and aluminum diethylphosphinate (1240), wherein the weight fraction of the 4(0,0-diethyl phosphoryl)glycoluril in the flame retardant composition is larger than zero. The flame retardant composition disclosed by the invention has the advantages of multi-element synergistic interaction, high material compatibility, high flame resistance, freeness from halogen, environmental friendliness, reduction in the application cost and the like, and can be applied to flame retardants such as polyester and polyamide.

Description

technical field [0001] The invention relates to a tetrakis(0,0-diethylphosphoryl) glycoluril flame retardant composition and an application method thereof. The flame retardant composition can be used for the flame retardant of engineering plastics such as polyester and polyamide. Background technique [0002] The compounding technology of flame retardants is an effective way to improve the comprehensive cost-effectiveness of flame retardants. The flame retardant of most polymers is achieved through the compounding of flame retardants. Therefore, the research on compounding technology of flame retardants has been become a hot topic. At present, my country is the world's largest polyester producer, but the flame retardant modification rate of polyester in my country is less than 1%, while the flame retardant modification rate of polyester in developed countries is 10-15%. The level of combustion modification rate still has a lot of room for development. Therefore, it is of gr...
