Abstract

The invention discloses a preparation method of an anti-static PP (polypropylene) master batch. The preparation method comprises following operation steps: (1), samarium chloride and ytterbium chloride are added to water and are mixed and stirred uniformly, then dodecyl salicylic acid is added, after uniform mixing and stirring and a thermal insulation reaction, an upper water layer is removed, and dodecyl salicylic acid rare earth is obtained; (2), after dodecyl salicylic acid rare earth and sodium dodecyl benzene sulfonate are mixed uniformly, an anti-static agent is prepared; (3), after PPresin, the anti-static agent, an antioxidant and talcum powder are mixed uniformly, the mixture is added to a twin-screw extruder and subjected to extrusion and pelletization, and the anti-static PP master batch is prepared. The preparation method of the anti-static PP master batch is low in cost and simple to operate, and a prepared finished product is excellent in washing durability and moistureresistance.

Description

technical field [0001] The invention belongs to the technical field of preparation of plastic master batches, and in particular relates to a preparation method of antistatic polypropylene master batches. Background technique [0002] Antistatic masterbatch is obtained by high-speed mixing of carrier and antistatic system, extrusion molding, and then pelletizing. It is used to reduce the surface resistance of materials and prevent the adverse effects of static electricity on various industrial sectors and humans. Polypropylene is a thermoplastic resin produced by the polymerization of propylene. It has a lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but it has stronger impact strength. The impact strength of polypropylene increases with the increase of propylene content. The Vicat softening temperature of polypropylene is 150°C. Due to the high degree of crystallinity, the surface stiffness and scratch resistance of this material a...
