Embodiment 1

[0032] The environment-friendly type antistatic flame retardant polypropylene material of the present embodiment is made of the following components by weight:

[0033] 100kg of polypropylene powder resin, 18kg of piperazine pyrophosphate, 5kg of pentaerythritol diphosphate melamine salt, 3kg of melamine cyanurate, 1.5kg of graphene, 1.5kg of zinc stearate.

[0034] The preparation method of the above-mentioned environment-friendly antistatic flame retardant polypropylene material is:

[0035] ①Pour the above components into a high-speed mixer according to the formula and mix at 900n / min until the friction heat generated by the mixing makes the temperature of the material rise to 80°C-90°C and stop stirring, then add graphene and stir at a low speed Stir for 2 minutes at 100 rpm, discharge and cool;

[0036] ② Feed the cooled mixture into the twin-screw extruder for melting and extrusion. The temperature of each zone of the twin-screw extruder is: T 1 =140°C, T 2 =150, T 3...

Abstract

The invention relates to an environment-friendly antistatic and flame-retardant polypropylene material and a preparation method thereof. The polypropylene material of the invention has good flame-retardant properties, mechanical properties, water-resistant desorption properties and environmental protection properties, and meets the requirements of the "ROHS" directive promulgated by the European Union. . The present invention uses piperazine pyrophosphate, pentaerythritol diphosphate melamine salt, and melamine cyanurate as the main halogen-free composite flame retardant system, supplemented by the flame retardant synergistic effect of graphene, enhanced toughening and electrical conductivity, The flame retardant system can obtain a better flame retardant effect at a lower dosage, and the prepared polypropylene material has better mechanical properties, the oxygen index is greater than 35%, the vertical combustion reaches V-0 level, and the thermal decomposition temperature Higher than 450°C, it has long-term antistatic effect, and has better resistance to water desorption.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an environment-friendly antistatic flame retardant polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is widely used in the manufacture of components such as electronic appliances, auto parts, and modern office supplies due to its good heat resistance, low water absorption, and high comprehensive mechanical properties. However, due to the defects of flammability and poor antistatic properties of polypropylene, its application in some fields is limited. [0003] Currently used flame retardant polypropylene materials include halogen / antimony flame retardant polypropylene and halogen-free flame retardant polypropylene materials. The former type of flame-retardant polypropylene is prone to secondary disasters due to thermal cracking and a large amount of corrosive toxic gases and smoke generated during combustion. Therefore, accordi...
