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 type extruder, and measure it with a HC900-2 type 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 tetrakis (0-methyl-phenylphosphinoyl) glycoluril flame retardant composition. The flame retardant composition is composed of tetrakis (0-methyl-phenylphosphinoyl) glycoluril (TMPG) 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-methyl-phenylphosphinyl) 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 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-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...
