PP calcium plastic material for improving printing suitability for packaging box and preparation method of PP calcium plastic material

Abstract

The invention provides a PP calcium plastic material for improving printing suitability for a packaging box body and a preparation method of the PP calcium plastic material. The PP calcium plastic material for improving the printing suitability for the packaging box body is prepared from the following raw materials in parts by mass: 30-60 parts of PP resin, 1-5 parts of PE resin, 40-65 parts of ground calcium carbonate, 1-3 parts of borate multifunctional additive and 0.5-1 part of anti-aging agent. The PP calcium plastic material for improving the printing suitability for the packaging box body is obtained by conducting uniform stirring, conducting granulating by a double-screw extruder and finally conducting extruding and molding by a single screw. According to the PP calcium plastic material for the packaging box body and the preparation method thereof, the formula is simple, printing coloring is obviously improved, and the mechanical property is good; and the preparation method issimple in process, convenient to operate and control, high in production efficiency and low in production cost.

Description

technical field

[0001] The invention relates to the field of polymer materials, in particular to a PP calcium-plastic material for packaging boxes with improved printing suitability, and further relates to a preparation method of the material. Background technique

[0002] Calcium-plastic composite materials are high-density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC) and other thermoplastic resins, adding high-content inorganic fillers such as calcium carbonate, various antioxidants, lubricants, etc. This kind of additive is made by heating, plasticizing, extruding / calendering. Compared with traditional carton packaging materials, the packaging box prepared by using it has the advantages of compression resistance, impact resistance, moisture resistance, recyclability, green environmental protection, etc. be widely used.

[0003] With the wide application of calcium-plastic composite materials in the outer packaging of commodities, and the different e...
