Description

technical field [0001] The invention relates to the technical field of PP / PE materials, in particular to an extrusion grade foamed PP / PE material and a preparation method thereof. Background technique [0002] Polyethylene (PE) and polypropylene (PP) are both crystalline thermoplastic resins, both of which have the advantages of light weight, low price, good electrical insulation performance, and convenient processing. The PP / PE plastic alloy material made by blending has effectively improved the mechanical strength, heat resistance and self-lubricity of a single material, but there are still some problems in the PP / PE plastic alloy material, such as the compatibility of PP and PE. The performance is not good enough, the wear resistance is poor, the mechanical properties are not good, etc. Therefore, it is necessary to develop an extrusion-grade foamed PP / PE material with good comprehensive performance. Contents of the invention [0003] In view of the above deficiencies...
