Problems solved by technology

[0004] At present, the flame retardants commonly used in the market for halogen-free flame-retardant reinforced nylon are OP1312 and OP1311 from Klein, Germany, which are completely dependent on imports, expensive, and unstable supply. Difficult, with high requirements for machine and process
And because flame-retardant reinforced nylon has high resistance characteristics, it is easy to generate static electricity and accumulate continuously when nylon products contact or rub with other materials. A series of security risks

Embodiment 1

[0023] Preparation of a new type of antistatic halogen-free flame-retardant reinforced masterbatch for polyamide, the halogen-free flame-retardant masterbatch is composed of the following raw materials in parts by mass (wt%):

[0024] PA 28%, alkyl hypophosphite 25%, melamine polyphosphate 25%, zinc borate 25%, CTI accelerator 5%, toughening agent 4%, lubricant 0.7%, antioxidant 0.3%, antistatic agent 1.2%, 0.8% silane coupling agent; the above mixture is added to a twin-screw extruder, melted and reacted, extruded and granulated, so as to prepare a new type of antistatic halogen-free flame-retardant reinforced masterbatch for polyamide.

Embodiment 2

[0026] Add the special antistatic halogen-free flame-retardant reinforced masterbatch prepared above to PA6 to carry out glass fiber reinforced flame-retardant modification. The antistatic halogen-free flame-retardant reinforced PA6 is composed of the following raw materials, and its mass parts (wt %) ratios are:

[0027] 43.5% of PA6, 0.5% of silane coupling agent, 30% of alkali-free glass fiber yarn, 25% of antistatic and flame-retardant reinforced masterbatch for polyamide, 0.3% of antioxidant, and 0.7% of lubricant; add the above mixture to the twin-screw Extruder, melt reaction, extrusion granulation, drying at 110°C-120°C for 4-6 hours, injection molding into standard strips according to national standards, and performance testing.

Embodiment 3

[0029] Add the special antistatic halogen-free flame-retardant reinforced masterbatch prepared above to PA66 to carry out glass fiber reinforced flame-retardant modification. The antistatic halogen-free flame-retardant reinforced PA66 is composed of the following raw materials, and its mass parts (wt %) ratios are:

[0030] 43.5% of PA66, 0.5% of silane coupling agent, 30% of alkali-free glass fiber yarn, 25% of antistatic and flame-retardant reinforced masterbatch for polyamide, 0.3% of antioxidant, and 0.7% of lubricant; add the above mixture to the twin-screw Extruder, melt reaction, extrusion granulation, drying at 110°C-120°C for 4-6 hours, injection molding into standard strips according to national standards, and performance testing.

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...
