Abstract
The invention relates to a thermoplastic product in the rapid consumption field and particularly relates to a straw product taking polypropylene as a main base material, and a manufacturing method. The straw product comprises the polypropylene, thermoplastic shape memory macromolecules, a compatilizer, a lubricating agent and an antioxidant. According to the straw with the recoverable shape and the manufacturing method, a deformation temperature of the straw is mainly determined by the property of a shape memory macromolecular material; the deformation temperature of a polypropylene straw is low and is close to the temperature of a human body, so that the polypropylene straw is applicable to room-temperature or low-temperature beverages; the deformation temperature of a polycaprolactone straw is high, so that the polycaprolactone straw can be applied to hot beverages. The content of polypropylene is improved while the content of the shape memory macromolecular material is reduced, and thus the deformation temperature of the product is improved.
