Example Embodiment

[0021] Example 1: The high-efficiency antistatic masterbatch for the BOPP film is characterized by containing the following components and contents (parts by weight):

[0022] Polypropylene 70

[0023] Antistatic agent 30

[0024] The antistatic agent is composed of the following materials in the following proportions (parts by weight):

[0025] Non-ionic glycerol fatty acid ester 4

[0026] Non-ionic ethoxy amine 7

[0027] Semi-ionic borate derivative 1.5

[0028] The production method of high-efficiency antistatic masterbatch for BOPP film is characterized by the use of precision weighing system ingredients, the antistatic agent and carrier polypropylene are fully mixed and then the melt is extruded by a twin-screw extruder, and the extruder produces The temperature is controlled at 215°C, the current is controlled at 440mA, the speed of the extruder is controlled at 420r / min, the head pressure is controlled at 18Pa / h, and the melt temperature is controlled at 220°C. After the ...

Abstract

The invention relates to a high-efficient antistatic master batch used for BOPP membranes and a production process thereof, aiming at solving the problems of the prior art that various other functional promoters should be added, the process is complex, the process cost is high, the antistatic agent content in the master batch is low, the amount of added membrane is high, the membrane fabrication cost is increased and the antistatic effect is not ideal. The invention adopts the technical proposal that: the master batch comprises the components with the following content (weight portions): 62 to 70 portions of polypropylene and 30 to 38 portions of antistatic agent; the antistatic agent can use the complexing agent of non-ionic glycerin fatty acid ester, non-ionic ethoxyamine and semi-ionic borate derivatives. The production process uses a precision system for batching; the antistatic agent and the polypropylene are mixed and then extruded by a double screw extruder with the extruder temperature being 215 to 225 DEG C, the electric current being 440 to 460mA, the revolution being 420 to 430r/min, the die pressure being 18 to 20MPa/h and the melt temperature being 220 to 230 DEG C; the melt is extruded, dried, cooled and granulated and then the master batch is made.

Description

Technical field [0001] The invention belongs to the functional auxiliary agent of plastic film and its process, and specifically refers to a high-efficiency antistatic masterbatch for BOPP film (ie, biaxially oriented polypropylene film) and its production process. Background technique [0002] BOPP film is a very important flexible packaging material. Due to its colorless, odorless, tasteless, non-toxic characteristics, high tensile strength, high impact strength, high toughness, and excellent optical properties, it is used in the packaging field. It has a very wide range of applications and its market continues to expand. In 2007, the output of BOPP film in my country reached 2 million tons per year. By the end of 2008, more than 20 BOPP film production lines will be put into production. In the future, the annual output of BOPP film will reach 250~300. 10,000 tons / year. However, during the processing or use of BOPP film, the friction between the films will generate static elect...
