Antistatic, halogen-free, and fire-retardant enhanced master batch dedicated for polyamide and preparation method thereof

Abstract

The invention relates to an antistatic, halogen-free, and fire-retardant enhanced master batch dedicated for polyamide and a preparation method thereof. The fire-retardant master batch is composed of following components in parts by weight: 25 to 50 parts of PA, 15 to 30 parts of alkyl phosphinate fire-retardant, 15 to 30 parts of melamine polyphosphate fire retardant, 8 to 15 parts of zinc borate fire retardant, 4 to 6 parts of CTI improver, 1 to 1.5 parts of antistatic agent, 3 to 8 parts of flexibilizer, 0.5 to 1 part of coupling agent, 0.7 to 1.5 parts of lubricant, and 0.3 to 1 part of anti-oxidant. The sum of the weight ratio of components mentioned above is 100 wt%. The fire-retardant master batch is used to produce fire-retardant enhanced and modified nylon, meets standards of the United States underwriters laboratories (UL)-941.6mm and a higher V-0 grade, simultaneously achieves that glowing wire temperature (GWIT) is equal to or larger than 750 DEG C and the CTI value is equal to or larger than 600 V, also has a antistatic performance, meets European Union RoHS, International Electrotechnical Commission (IEC) halogen-free and Reach rule requirements, is easy to use and excellent in comprehensive performance, and does not affect color matching.

Description

technical field

[0001] The invention relates to the field of flame-retardant modification of polymer materials, in particular to a novel antistatic halogen-free flame-retardant reinforced masterbatch for polyamide and a preparation method thereof. Background technique

[0002] Nylon is a kind of engineering plastic with excellent performance, wide range of uses and large dosage. It is widely used in the fields of electronics, transportation, construction, vehicle manufacturing, office supplies, sports equipment and other fields. It has excellent comprehensive properties: high strength, high toughness Good (wet state); good oil resistance, organic solvent resistance and chemical resistance; small friction coefficient, excellent self-lubricating performance; good processing performance. With the development of electronic, electrical and communication equipment towards miniaturization, light weight and high performance, the amount of nylon modified materials is increasing. How...
