Plant derived plastic blend and a method of manufacturing the same

摘要

Provided are a plant derived plastic blend and a manufacturing method thereof in which high density polyethylene and polylactic acid are microscopically mixed to improve the mechanical properties of the plant derived plastic blend. The plant derived plastic blend comprises 10 wt % or more and 90 wt % or less of a plant derived polyethylene and 10 wt % or more and 90 wt % or less of a plant derived polylactic acid to achieve a total of 100 wt %, and further contains 1 wt % or more and 20 wt % or less of a compatibilizing agent. The manufacturing method of the plant derived plastic blend is carried out in a cylinder by applying a shear flow field and a stretching field and melt-kneading raw material containing the plant derived polyethylene, the polylactic acid and the compatibilizing agent.

1. A plant derived plastic blend comprising:
10 wt % or more and 90 wt % or less of a plant derived high density polyethylene and 10 wt % or more and 90 wt % or less of a plant derived polylactic acid to achieve a total of 100 wt %; and further containing 1 wt % or more and 20 wt % or less of a compatibilizing agent, wherein a modulus of elongation of the plant derived plastic blend is 950 MPa or more and a breaking elongation of 4% or more, and wherein a proportion being 1 μm or less of a domain size of the plant derived polylactic acid is 60% or more in the case where the plant derived high density polyethylene is a matrix, and a proportion being 1 μm or less of a domain size of the plant derived high density polyethylene is 40% or more in the case where the plant derived polylactic acid is a matrix.
