Abstract

The invention relates to the technical field of a macromolecular material, and concretely discloses a high thermal stability masterbatch for PE / PP film and a preparation method thereof. The high thermal stability masterbatch is prepared from the following raw material ingredients in parts by weight: 50 to 70 parts of PE resin, 40 to 60 parts of PP resin, 30 to 50 parts of maleic anhydride graftedcompatibility agents, 10 to 20 parts of sodium stearate, 1 to 5 parts of antioxidants and 5 to 10 parts of thermal stabilizing agents. The masterbatch uses newly prepared thermal stabilizing agents; the thermal stability of the plastic film prepared from PE resin or PP resin and mixed resin of PE resin and PP resin can be greatly improved. In addition, the PP or PE film prepared by adding the highthermal stability masterbatch does not have film shrinkage after the placement for 48 hours under the condition of 110 DEG C.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high thermal stability masterbatch used for PE / PP films and a preparation method thereof. Background technique [0002] PE protective film, that is, polyethylene film, is the simplest polymer organic compound and the most widely used polymer material in the world today. It is often used in the preparation of sheets, plates, electronic appliances, and handicrafts. But the heat resistance stability of PE protective film is not good. In order to further improve the thermal stability of the material, a common method is to add masterbatches during the preparation process. [0003] In addition, with the needs of life and industrial production, in order to further improve the comprehensive performance of single-component materials, composite membranes have emerged as the times require. The common one is PE / PP composite film, which is composed of polyethylene PE and polypr...
