Abstract
The invention discloses biodegradable plastics comprising the following components by weight: 70-90 parts of poly(ethylene carbonate)polyurethane, 20-50 parts of starch, 3-8 parts of a modifying agent, 10-20 parts of a plasticizer, and 10-20 parts of a lubricant. The biodegradable plastics disclosed by the invention adopt the starch and poly(ethylene carbonate)polyurethane as main components, can be decomposed into carbon dioxide and water after being discarded, thereby having no pollution to the environment; and by adding the modifying agent and the lubricant, the air permeability is improved.
Description
Technical field
The present invention relates to chemical production field, relate to specifically a kind of biodegradable plastics in this field.
Background technology
Plastics are of many uses, but have the problem of hard degradation, cause environmental pollution.Although use polylactic resin can produce the plastics that can be degraded, its production cost is higher, ventilation property is also poor, is never used widely.
Summary of the invention
It is low that technical problem to be solved by this invention is just to provide a kind of production cost, has the biodegradable plastics of good permeability.
The present invention adopts following technical scheme:
A kind of biodegradable plastics, comprise the composition of following weight content: polymerized thylene carbonate urethane 70-90 part, starch 20-50 part, properties-correcting agent 3-8 part, softening agent 10-20 part, lubricant 10-20 part.
The invention has the beneficial effects as follows:
Biodegradable plastics disclosed in this invention, use starch and polymerized thylene carbonate urethane as main component, after discarding, can be degraded to carbonic acid gas and water, environmentally safe; Improve its permeability by increasing properties-correcting agent and lubricant.
Embodiment
