Abstract

The invention provides a preparation method of a novel PP hollow plate. The preparation method comprises the following steps: S1, uniformly mixing 18-25 parts by weight of a random copolymerized PP material, 16-22 parts by weight of a wire drawing grade PP material, 18-25 parts by weight of a homopolymerizd PP material, 18-25 parts by weight of a high-transmittance copolymerized PP material and 16-25 parts by weight of a wire drawing grade PE material; and S2, carrying out extrusion molding on the obtained mixture in a range of 193-198 DEG C to form the novel PP hollow plate.

Description

technical field [0001] The invention relates to a novel PP hollow board and a preparation method thereof. Background technique [0002] The new PP hollow sheet (polypropylene hollow sheet) is made of polypropylene raw material mixed with polyethylene raw material and extruded through the hollow sheet production line. The new PP hollow board is a new type of environmentally friendly packaging material. It will not generate dust during use and has a long service life, which is more than 4-10 times the life of corrugated cardboard. It can be recycled and gradually replaces paper corrugated board. The trend is mainly reflected in product packaging. In addition, due to the light weight, good toughness, flexible size and relatively low cost of the new PP hollow board, the new PP hollow board turnover box equipped with various accessories has the tendency to replace the injection molded turnover box. However, the existing new PP hollow board has low toughness and tensile strength...
