[0002] Polypropylene material is cheap, but it has defects such as poor toughness and easy to fold white
Polypropylene is divided into polar and non-polar according to polarity. Polar is mainly used in some situations where the polarity of the material is required, such as for polar materials such as nylon and polyolefin non-polar materials. The middle adhesive layer of the co-extruded composite film, two kinds of adhesive products are commonly used in the market at present, one is the common adhesive, the price is lower but the high temperature resistance is poor, the film material that uses this adhesive as the middle layer co-extruded to make further progress When heat-sealing the package, the

Abstract

The invention belongs to the technical field of chemistry and chemical engineering, and particularly relates to a folding-white free transparent polypropylene material and a preparation method thereof. A polar polypropylene material is prepared from components in parts by weight as follows: 50-100 parts of polypropylene, 5-50 parts of elastomers, 5-30 parts of polar materials, 0.1-1 part of a nucleating agent and 0.5-3 parts of other auxiliaries; a non-polar polypropylene material is prepared from components in parts by weight as follows: 50-100 parts of polypropylene, 5-50 parts of elastomers, 0.1-1 part of an anti-copper agent, 0.1-1 part of a nucleating agent and 0.5-3 parts of other auxiliaries; the raw materials are mixed and added to a double-screw extruder to be extruded and granulated. The polypropylene material is good in flexibility, free of folding white, low in cost and suitable for replacing polypropylene materials in the prior art.
