Problems solved by technology

[0002] Polyester materials are widely used in industrial production and people's daily life, but most polyester materials are flammable
Especially as engineering plastics or decoration materials, flame retardant must be required. However, flame retardants with excellent cost performance, especially halogen-free flame retardants for polyester, are still rare in the market. By compounding or designing flame retardant molecules It is the main direction of current research to achieve the purpose of excellent flame retardants with structures containing multiple flame retardant elements.

Embodiment 1

[0027] Example 1 Add different proportions of TMPG 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.

[0029]

Embodiment 2

[0030] Example 2 Add different proportions of TMPG 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 type extruder, and measure it with a HC900-2 type oxygen index measuring instrument The limiting oxygen index, the results are shown in Table 3.

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

[0032]

[0033] It can be seen from Table 3 that when 12 parts of TMPG and 8 parts of MCA are used in combination, the limiting oxygen index is increased by 3 compared with that of TMPG alone, reaching 31, 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 TMPG and MPP 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 4.

[0036]

[0037] It can be seen from Table 4 that when 12 parts of TMPG and 8 parts of MPP are used in combination, the limiting oxygen index is increased by 2 compared with that of TMPG alone, reaching 30, which has a good synergistic flame retardant effect.

Abstract

The invention relates to a tetra(0-methyl-phenylphosphinyl)glycoluril (TMPG) flame retardant composition. The flame retardant composition is prepared from TMPG 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 TMPG 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-methyl-phenylphosphinoyl) 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] Polyester materials are widely used in industrial production and people's daily life, but most polyester materials are flammable. Especially as engineering plastics or decoration materials, flame retardant must be required. However, flame retardants with excellent cost performance, especially halogen-free flame retardants for polyester, are still rare in the market. By compounding or designing flame retardant molecules It is the main direction of current research to achieve the purpose of excellent flame retardants with structures containing multiple flame retardant elements. [0003] The invention discloses a tetrakis (0-methyl-phenylphosphinoyl) glycoluril flame re...
