Abstract

The polyolefin elastomer (POE) was added to polypropylene (PP) to prepare PP composites, and the influence of different POE content on the properties of PP composites was explored. The results show that in terms of the mechanical properties of the material, the tensile strength decreases with the increase of POE content of the thermoplastic elastomer, while the elongation at break, bending strength and impact strength increase first and then decrease with the increase of POE content of the thermoplastic elastomer. Due to the addition of the filler, the composites have good thermal stability and reach the maximum value when the mass fraction of POE is 6%, and the mechanical properties are also optimal. After aging, compared with pure PP materials, PP composites can also maintain their excellent mechanical properties. Therefore, the prepared PP composites can be used in building water supply.
