Problems solved by technology

[0003] For CPP heat-sealable films, in the prior art, anti-adhesive masterbatch and slip agent masterbatch need to be added to the surface layer to effectively reduce the friction coefficient of the CPP heat-seal layer and achieve the required opening performance, but this method The process is complicated, and the timing and temperature of adding the two masterbatches need to be strictly controlled. At the same time, the amount of addition is large, which wastes a lot of manpower and material resources. It is a technical problem that needs to be overcome in the production of CPP heat-sealable films.

Abstract

The invention relates to high-efficiency composite type anti-sticking smooth master batch for producing a CPP (casting polypropylene) membrane. The high-efficiency composite type anti-sticking smooth master batch is specifically prepared from the following components in parts by mass: 75-80 parts of a polypropylene material, 7-11 parts of a silica material, 8-12 parts of an erucic acid material and 1-2 parts of a dispersing agent. Tests show that when a CPP heat-seal type membrane is prepared, to achieve a good anti-sticking and smooth effect, the addition ratio of the master bath is 0.4%, the addition ratio of a conventional additive is 0.2%, but the ratio of a polypropylene material in the master bath is as high as 80%, that is, the amount of the silica material and the erucic acid material is only 0.08%, which is far less than the amount of 0.2% of the conventional additive, so that the amount of the master batch can be greatly reduced, and the production cost of a company can be lowered.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to a high-efficiency composite anti-sticking and slippery masterbatch for CPP film production. Background technique [0002] CPP film, also known as unstretched polypropylene film, is a non-stretched, non-oriented flat extrusion film produced by melt casting quenching. Compared with blown film, it is characterized by fast production speed, high output, good film transparency, gloss, thickness uniformity, and excellent balance of isotropic properties. At the same time, because it is a flat extrusion film, the subsequent processes such as printing and lamination are extremely convenient, so it is widely used in the packaging of textiles, flowers, food, and daily necessities. [0003] For the CPP heat-sealing film, in the prior art, the surface layer needs to be added with anti-sticking agent masterbatch and slip agent masterbatch respectively, in order to effect...
