Embodiment 1

[0022] Each raw material is taken by weighing the following proportions by weight:

[0023] Polyethylene terephthalate-1,4-cyclohexanedimethanol PETG 83 parts, flame retardant triphenylphosphine oxide TPO 15 parts, nucleating agent sodium benzoate NaA 1 part, PEPQ antioxidant 0.5 part, 0.5 part of 1010 antioxidant.

[0024] Dry the weighed raw materials, then add them to a high-speed mixer and mix for 10 minutes, take them out, add them to a twin-screw extruder with a melting temperature of 150-240 ° C, extrude, and granulate to obtain the high transparency of the present invention Halogen-free flame retardant material. The process conditions of the twin-screw extruder are: the temperature of the first zone of the extruder is 140-160°C, the temperature of the second zone is 160-180°C, the temperature of the third zone is 180-200°C, the temperature of the fourth zone is 200-220°C, and the temperature of the fifth zone is 220- 240°C, the temperature in the sixth zone is 220-24...

Embodiment 2

[0026] Each raw material is taken by weighing the following proportions by weight:

[0027] 83 parts of polyethylene terephthalate-1,4-cyclohexanedimethanol PETG, 15 parts of flame retardant triphenyl phosphate, 1 part of nucleating agent sodium benzoate NaA, 0.5 part of PEPQ antioxidant, 0.5 part of 1010 antioxidant.

[0028] The preparation method is the same as in Example 1.

Embodiment 3

[0030] Each raw material is taken by weighing the following proportions by weight:

[0031] Polyethylene terephthalate-1,4-cyclohexanedimethanol PETG 88 parts, flame retardant triphenylphosphine oxide TPO 5 parts, flame retardant bisphenol A-bis(diphenyl phosphate ) 5 parts of BDP, 1 part of nucleating agent sodium benzoate, 0.5 part of PEPQ antioxidant, and 0.5 part of 1010 antioxidant.

[0032] The preparation method is the same as in Example 1.

Abstract

The invention discloses a high-transparency halogen-free flame retardant material and relates to the field of high-polymer materials. The flame retardant material is prepared from raw materials in parts by weight as follows: 80-95 parts of PETG (polyethylene terephthalate glycol) resin, 5-20 parts of a flame retardant, 0.1-1 part of a nucleating agent and 0.1-1 part of an antioxidant; the flame retardant is a halogen-free organophosphorus flame retardant and preferably is prepared from at least two of triphenylphosphine oxide, triphenyl phosphate, bisphenol A-bis(diphenyl phosphate), resorcinol bis(diphenyl phosphate), tetrakis(2,6-dimethylphenyl) 1,3-phenylene bisphosphate and polysulfonydipheylene phenylphosphonate through combination. With the adoption of multiple halogen-free flame retardants, the transmittance of PETG is not affected, and the transmittance of the PETG resin reaches 92% or above; the material is a low-smoke zero-halogen material and has an excellent flame retardant effect; a UL94 test reaches V-0(3mm), the LOI (oxygen index) is larger than 30. The high-transparency halogen-free flame retardant material can be widely applied to the field such as building materials, automobiles, electronics, spinning and the like which have higher requirements for flame retardancy and transparency.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a highly transparent halogen-free flame-retardant material. Background technique [0002] Polyethylene terephthalate-1,4-cyclohexanedimethanol (PETG) is a transparent, non-crystalline copolyester composed of terephthalic acid (PTA), ethylene glycol ( EG) and 1,4-cyclohexanedimethanol (CHDM) three monomers are polycondensed by transesterification. Compared with PET, PETG has more 1,4-cyclohexanedimethanol comonomer, and compared with PCT, it has more ethylene glycol comonomer. Therefore, the performance of PETG is quite different from that of PET and PCT. PETG sheet has outstanding toughness and high impact strength, its impact strength is 3 to 10 times that of modified polyacrylates, and has a wide processing range, high mechanical strength and excellent flexibility, compared with PVC transparency High, good gloss, easy to print, is a new generation of environmentally friendly ...
