Problems solved by technology

[0004] The most common catastrophic problems encountered in the production and use of BOPA films are due to the influence of static electricity, temperature, pressure and other factors, as well as the migration and penetration of short-chain molecules between the two layers of the film or due to the smooth surface of the film. Film adhesion occurs and it is difficult to separate, and in severe cases, the entire roll of film will be scrapped
In particular, modern plastic processing is developing towards automation, high speed and high quality. The faster the processing speed, the easier it is to generate static electricity due to friction, and the easier it is for films to stick together, which seriously hinders high-speed production.

Embodiment 1

[0015] Example 1: An anti-blocking BOPA film functional masterbatch, the raw material weight ratio of its preparation is: PA6: 95%; POSS-1: 5%. According to the ratio, the above raw materials are added into the twin-screw by using a precision weight-loss self-measurement feeding system, and then the melt is extruded and granulated. The speed is 50~100 kg / hour, and the speed of the granulator is 16~21HZ. Put the prepared masterbatch in a vacuum dryer at 100~150℃, and dry it for 16~24 hours to get the finished masterbatch.

Embodiment 2

[0016] Example 2: An anti-blocking BOPA film functional masterbatch, the raw material weight ratio of which is prepared is: PA6: 90%; POSS-1: 10%. According to the ratio, the above raw materials are added into the twin-screw by using a precision weight-loss self-measurement feeding system, and then the melt is extruded and granulated. The speed is 50~100 kg / hour, and the speed of the granulator is 16~21HZ. Put the prepared masterbatch in a vacuum dryer at 100~150℃, and dry it for 16~24 hours to get the finished masterbatch.

Embodiment 3

[0017] Example 3: An anti-blocking BOPA film functional masterbatch, the raw material weight ratio of its preparation is: PA6: 95%; POSS-2: 5%. According to the ratio, the above raw materials are added into the twin-screw by using a precision weight-loss self-measurement feeding system, and then the melt is extruded and granulated. The speed is 50~100 kg / hour, and the speed of the granulator is 16~21HZ. Put the prepared masterbatch in a vacuum dryer at 100~150℃, and dry it for 16~24 hours to get the finished masterbatch.

Abstract

The invention relates to a functional master batch for an antisticking BOPA film and a production method thereof, and the master batch is used to prepare a biaxial stretching BOPA film. The functional master batch is prepared by the following raw materials by weight: 90-95% of PA; and 5-10% of cage-shaped polyhedral oligomeric silsesquioxane (POSS), wherein the typical molecular formula of POSS is R7R' (SiO1.5)8, and the beneficial effects are that POSS is used as an antisticking agent, and fine aggregated micro-areas are formed on the surface of the BOPA film by the nano effects of POSS, which increase the roughness of the film surface and decrease the friction coefficient between films; on the other hand, the addition of POSS can reduce the surface polarity of the BOPA film, increase the hydrophobicity of the BOPA film, decrease the penetration of water, and thus improve the barrier property of the BOPA film, and has no adverse effect on mechanical properties; additionally, no other additive is required to be added during the production process of the master batch.

Description

technical field [0001] The invention relates to a biaxially stretched BOPA film functional masterbatch and a production method thereof. The masterbatch can be used to prepare a biaxially stretched BOPA film and is used in the field of plastic packaging. Background technique [0002] Biaxially oriented nylon film (BOPA) is an important material for the production of various composite packaging materials, and has become the third largest packaging material after polypropylene biaxially oriented film (BOPP) and polyester biaxially oriented film (BOPET). As a high barrier film base material, BOPA has higher barrier performance than polypropylene biaxially oriented film BOPP film, and BOPA film has high resistance to cracking, impact resistance, tensile strength and puncture resistance. The best, with excellent softness, good puncture resistance, wide application range (-60°C~150°C), acid, alkali, grease and various common organic solvents, especially excellent grease resistance,...
