Embodiment 1

[0028] Example 1 Add different proportions of TIPRG to polyester PET, mix evenly, extrude a sample strip with a diameter of about 3 mm 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.

Embodiment 2

[0031] Example 2 Add different proportions of TIPRG 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 an HC900-2 oxygen index measuring instrument The limiting oxygen index, the results are shown in Table 3.

[0032] Table 3 Flame retardant performance of flame retardant TIPRG and MCA compounded on PET

[0033]

[0034] It can be seen from Table 3 that when 12 parts of TIPRG and 8 parts of MCA are used in combination, the limiting oxygen index is increased by 2 compared with that of TIPRG used alone, reaching 30, which has a good flame retardant synergistic effect. And MCA is cheaper, which can reduce the cost.

Embodiment 3

[0035] Example 3 Add TIPRG and MPP in different proportions 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 it with an HC900-2 oxygen index measuring instrument The limiting oxygen index, the results are shown in Table 4.

[0038] It can be seen from Table 4 that when 12 parts of TIPRG and 8 parts of MPP are used in combination, the limiting oxygen index is increased by 2 compared with that of TIPRG used alone, reaching 30, which has a good synergistic flame retardant effect.

Abstract

The invention relates to a tetrakis (0,0-diisopropylphosphoryl) glycoluril flame retardant composition. The flame retardant composition is composed of tetrakis (0,0-diisopropylphosphoryl) glycoluril (TIPRG) and melamine cyanurate (MCA), melamine polyphosphate (MPP) and diethylphosphinic acid Any one, two or three kinds of aluminum (1240) are compounded and uniformly mixed in any weight ratio, and tetrakis (0,0-diisopropylphosphoryl) glycoluril is added to the flame retardant composition The weight fraction in is greater than zero. The flame retardant composition of the present invention has the advantages of multi-element synergy, good compatibility with materials, high flame retardancy, halogen-free environmental protection, and can reduce application costs, etc., and can be used for flame retardancy of polyester, polyamide, etc. agent.

Description

technical field [0001] The invention relates to a tetrakis(0,0-diisopropylphosphoryl) 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] Since halogenated flame retardants will produce toxic and harmful substances such as polybrominated dibenzodioxanes and polybrominated dibenzofurans during use, they will cause a certain degree of harm to the human body and the environment, so they are limited in many applications. The use of halogenated flame retardants, the current substitutes for halogenated flame retardants are mainly phosphorus nitrogen flame retardants. Phosphorus and nitrogen-based flame retardants have the advantages of high efficiency, low toxicity, and non-corrosion, so they have good market prospects. [0003] PET and PBT are the most widely used and largest output products in polyester res...
