Environment-friendly plastic bottle

Abstract

The invention discloses an environment-friendly plastic bottle. The environment-friendly plastic bottle is characterized by being prepared from the following substances in parts by weight: 30-50 parts of a polylactic acid / polypropylene co-mixture, 20-30 parts of a polylactic acid / starch / plant protein powder co-mixture, 10-20 parts of polypropylene / starch / plant protein powder co-mixture, 0.1-0.5 part of an anti-oxidant, 0.5-4.5 parts of a dispersing agent, 6-15 parts of a plasticizer, 1-10 parts of polylactic acid, 1-10 parts of polypropylene, 0.1-0.5 part of a nucleating agent, 1-10 parts of a compatilizer and 1-5 parts of a chain extender. The substances are dispersed by a high-speed mixer, are molten and mixed at a temperature of 180-220 DEG C through a twin-screw extruder, and are extruded to form a tyre mould; and finally, the tyre mould is subjected to blow-molding to obtain the environment-friendly plastic bottle. The environment-friendly plastic bottle provided by the invention is low in production cost, is excellent and stable in mechanical property, is degradable, and is small in environmental damage.

Description

technical field [0001] The invention relates to the technical field of plastic product production, in particular to an environment-friendly plastic bottle. Background technique [0002] With the popularity of plastic packaging bottles, the problems it brings are becoming more and more obvious. Due to its good corrosion resistance, some waste plastic packaging bottles that cannot be reused are difficult to be decomposed and returned to nature, resulting in the accumulation of waste plastics. , This is what we often call "white pollution". The main components of "white pollution" are polypropylene, polyvinyl chloride and polyethylene, which can remain in the field for decades without degrading, and accumulate in the soil plow layer year by year, resulting in soil compaction, poor permeability, and hindered root growth. Stubble crop yields have declined, some by more than 20 percent, and the situation is worsening. The resulting negative environmental effects have aroused ser...
