preparation example Construction

[0074] The present invention has no special limitation on the preparation method of the film material of the BOPP film, which can be obtained by melting and blending the base material and the anti-aging composition, and then extruding and granulating. In the present invention, there is no special limitation on the preparation method of the BOPP film from the film material, and it can be carried out according to the conventional film making method well known to those skilled in the art.

[0075] The BOPP film provided by the invention is added with the anti-aging agent composition provided by the invention, so it exhibits excellent abnormal performance. The experimental results show that: compared with the BOPP film material added with traditional anti-aging agent, the BOPP film material provided by this application has no adverse effect on haze, low friction coefficient and ash content, significantly improved long-term anti-aging effect, and effectively solves the phenomenon of...

Abstract

The invention provides an anti-aging composition and a BOPP film. The anti-aging composition provided by the invention is prepared from the following components: an amine synergist, a hindered phenolantioxidant, a phosphite antioxidant, an acid acceptor and a processing aid, wherein the amine synergist is a compound shown as a formula (1) and / or a compound shown as a formula (2). The specific amine synergist shown as the formula (1) and / or the formula (2) is matched with the hindered phenol antioxidant, the phosphite antioxidant and the acid acceptor for combined action, and the processing aid is supplemented, so the problem that the end face of the BOPP film becomes red can be solved, the friction coefficient of the film can be reduced, antioxidant effect is improved, and a low ash content is kept.

Description

technical field [0001] The invention relates to the field of polymer additives, in particular to an antiaging composition and a BOPP film. Background technique [0002] Biaxially oriented polypropylene (BOPP) film has the characteristics of high gloss, high stiffness, good barrier performance, and high impact strength. It is widely used in printing, adhesive tape, clothing packaging, cigarette packaging and other fields, and is a rapidly growing Special polypropylene materials, and with the improvement of polypropylene polymerization technology, conventional wire drawing materials used to produce BOPP film technology is becoming more and more mature. [0003] The production of BOPP film material is to first make the melt of high molecular polypropylene into a sheet or a thick film through a long and narrow machine head, and then in a special stretching machine, at a certain temperature and a set speed, simultaneously or separately Stretching in two vertical directions (long...
