Embodiment 1

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

[0028] Table 2 Flame retardant performance of flame retardant TBG on PET

[0029]

Embodiment 2

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

[0031] Table 3 Flame retardant performance of flame retardant TBG and MCA compounded on PET

[0032]

[0033] It can be seen from Table 3 that when 12 parts of TBG and 8 parts of MCA are used in combination, the limiting oxygen index is increased by 3 compared with that of TBG used alone, reaching 29, which has a good flame retardant synergistic effect. And MCA is cheaper, which can reduce the cost.

Embodiment 3

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

[0036]

[0037] It can be seen from Table 4 that when 12 parts of TBG and 8 parts of MPP are used in combination, the limiting oxygen index is increased by 3 compared with that of TBG alone, reaching 29, which has a good synergistic flame retardant effect.

Abstract

The invention relates to a 4(0,0-dibutyl phosphoryl)glycoluril flame retardant composition. The flame retardant composition is prepared by compounding and uniformly mixing 4(0,0-dibutyl phosphoryl)glycoluril (TBG) 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-dibutyl 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 (O, O-dibutylphosphoryl) glycoluril flame retardant composition and an application method thereof. The flame retardant composition can be used for flame retardancy of engineering plastics such as polyester and polyamide. Background technique [0002] After a century of development, polyester materials have rapidly penetrated into various fields of modern society and played an increasingly important role. However, the flammability of most polyesters has greatly restricted the materials in many applications. With the enhancement of people's awareness of safety and environmental protection, it has become an important research direction to develop polyester flame retardants with high flame retardant efficiency, little harm to human body and environmental pollution. Phosphorus-nitrogen synergistic flame retardant, with the characteristics of halogen-free, low toxicity, high decomposition temperature, and good mechanical p...
