Embodiment 1

[0028] Example 1 Add different proportions of TMG 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.

[0030]

Embodiment 2

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

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

[0033]

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

Embodiment 3

[0035] Example 3 Add different proportions of TMG and MPP 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 a HC900-2 oxygen index tester The limiting oxygen index, the results are shown in Table 4.

[0037]

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

Abstract

The invention relates to a tetrakis(0,0-dimethylphosphoryl) glycoluril flame retardant composition. The flame retardant composition is composed of tetrakis (0,0-dimethylphosphoryl) glycoluril (TMG) and melamine cyanurate (MCA), melamine polyphosphate (MPP) and aluminum diethylphosphinate Any one, two or three of (1240) are compounded and uniformly mixed in any weight ratio, and the tetrakis (0,0-dimethylphosphoryl) glycoluril in the flame retardant composition The weight fraction 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 retardant performance, halogen-free environmental protection, and can reduce application costs, etc., and can be used for flame retardant of polyester, polyamide, etc. agent.

Description

technical field [0001] The invention relates to a tetrakis(0,0-dimethylphosphoryl) 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] Widely used polyesters mainly include PET and PBT, which are the earliest linear thermoplastic polymers to achieve industrial production. It has excellent fatigue resistance and friction resistance, excellent aging resistance, outstanding electrical insulation performance, good processing performance, stable to most organic solvents and inorganic acids, and is mainly used for spinning and engineering plastics. In recent years, polyester PET is used as a flame-retardant modified spinning, and polyester PBT is used as a flame-retardant modified engineering plastic. Therefore, flame-retardant polyester technology has gradually become one of the research hotspots. [0003] R...
