Embodiment 1

[0029] A kind of halogen-free flame-retardant nylon 66 masterbatch, by weight percentage, its composition is:

[0030] Polyhexamethylene adipamide 86.3

[0031] Melamine cyanurate 12

[0032] Tetraphenylresorcinol diphosphate 1

[0033] 3,5-di-tert-butyl-4-hydroxyphenyl propionate octadecyl 0.5

[0034] Bis-2,2,6,6-tetramethylpiperidinol sebacate 0.2

[0035] A preparation method of halogen-free flame-retardant nylon 66 masterbatch. The above-mentioned components are mixed in a high-speed mixer in proportion for several minutes, and then added to a screw extruder for granulation. The processing temperature is 200-300 ° C, and the screw rotation speed is 200-580 rpm.

Embodiment 2

[0037] A kind of halogen-free flame-retardant nylon 66 masterbatch, by weight percentage, its composition is:

[0038] Polyhexamethylene adipamide 88.5

[0039] Melamine cyanurate 10

[0040] Tetraphenylresorcinol diphosphate 1

[0041] 3,5-di-tert-butyl-4-hydroxyphenyl propionate octadecanyl 0.3

[0042] Bis-2,2,6,6-tetramethylpiperidinol sebacate 0.2

[0043] Others are the same as in Example 1.

Embodiment 3

[0045] A kind of halogen-free flame-retardant nylon 66 masterbatch, by weight percentage, its composition is:

[0046] Polyhexamethylene adipamide 85

[0047] Melamine cyanurate 12.5

[0048] Tetraphenylresorcinol diphosphate 2

[0049] 3,5-di-tert-butyl-4-hydroxyphenyl propionate octadecanyl 0.3

[0050] Bis-2,2,6,6-tetramethylpiperidinol sebacate 0.2

[0051] Others are the same as in Example 1.

Abstract

The invention discloses a halogen-free flame-retardant nylon 66 masterbatch, which comprises the following components in percentage by weight: 20 to 90 percent of polyhexamethylene adipamide, 5 to 60 percent of flame retardant A, 5 to 60 percent of flame retardant B, 0.1 to 2 percent of antioxidant and 0.1 to 2 percent of light stabilizer. The invention has the advantages that: different from a method of directly adding the flame retardants, the method comprises the following steps of: preparing a halogen-free flame-retardant masterbatch taking nylon 66 as a matrix and blending with nylon 66 to obtain halogen-free flame-retardant nylon 66 masterbatch; and the halogen-free flame-retardant nylon 66 masterbatch is more convenient to store and use and has better operability and higher mechanical properties and flame retardancy.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant nylon 66 masterbatch, in particular to a halogen-free flame-retardant nylon 66 masterbatch suitable for manufacturing environmentally friendly nylon products. Background technique [0002] As we all know, nylon is one of the most commonly used engineering plastics. It has good wear resistance, strong corrosion resistance, and excellent processing performance. It is widely used in automobiles, electronics, living appliances, packaging and other fields. But its flammable shortcomings limit its further application. According to the theory of "phosphorus-halogen synergistic flame retardant", nearly 70% of the flame retardants used in the flame-retardant nylon 66 masterbatch on the market are halogen-containing flame retardants, mainly polybrominated diphenyl ethers and polybrominated biphenyls, This kind of substance has high flame retardant efficiency, less dosage, and has little effect on the physi...
