Problems solved by technology

The masterbatch formula system is too complicated, and there are many types of small molecule additives, which will affect the processing of fully degradable material products, easily cause small molecule precipitation and other problems, and there is a certain risk
CN102040814A provides a black masterbatch specially used for polylactic acid-based degradable plastics. The formula system also contains petroleum-based non-degradable additives such as polyethylene wax, ethylene-vinyl acetate wax and EBS, which cannot realize the real sense of color masterbatch. Completely degraded
[0004] Degradable materials have experienced the development from "degradable" to "full degradable". Partially degradable materials such as starch-filled polypropylene or polyethylene materials, only the starch part can be degraded, so the traditional color masterbatch with polyethylene as the carrier It can be used in this kind of degradable material products, but degradable materials have now developed to the stage of fully degradable materials, which requires that the coloring masterbatch of fully degradable material products should also have the performance of complete degradation. None of the several patents achieved the complete degradability of the composition of the masterbatch

Abstract

The embodiment of the invention discloses a non-petroleum base complete degradation master batch which comprises the following components in percentage by weight: 30%-50% of carrier, 20%-70% of pigment and 0-60% of stuffing, wherein the carrier is a biological base complete degradation polymer; the biological base complete degradation polymer comprises one or two of hydroxy fatty acid ester PHA series, polylactic acid PLA and polydiethylene glycol sebacate PBS. The master batch prepared by the invention contains no petroleum base and no degradable addition agent; and the needed carrier is derived from renewable resources, thereby realizing the complete degradation in the true sense and more effectively promoting the application of a degradable material and the protection of environments.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a color masterbatch and a preparation method thereof, in particular to a non-petroleum-based degradable color masterbatch and a preparation method thereof Background technique [0002] In the past nearly one hundred years, the polymer material industry has achieved rapid development. The application and development of synthetic polymer materials have greatly facilitated people's lives, but the extensive use of disposable non-degradable products has brought serious environmental pollution problems. The problem of "white pollution" has attracted global attention. Countries have invested manpower and financial resources in the research and development of fully biodegradable materials. After nearly two decades of development, the research and development of fully degradable materials has made great progress. Fully degradable materials Products are gradually accepted by people because o...
