Description
Technical field
The invention belongs to wrapping material preparing technical field, be specifically related to a kind of degradable package material masterbatch and preparation method thereof.
Background technology
Degradable plastics be utilize plant straw etc. to make to human body and eco-friendly article, be different from the plastics of three large synthesis, after discarded, under bioenvironmental effect, can disintegrate, to people or environment all harmless, belong to Green Packaging.Degradable plastic bag is a kind of One-stop Shopping bag of " can degrade, easily degrade ".Degradable plastic bag, from the difference of raw material Sum decomposition factor, can be divided into two kinds: the plastics bag that the biodegradation agents such as one is based on vinyon, blending starch are made, and is also called biodegradation type plastics bag.This plastics bag mainly depends on microbial process to decompose.But the plastic degradation of bulk can only be become less unit of plastic by this degradable plastics, and the composition of plastic molecules does not have completely dissolve, so its degraded is limited.Another kind is based on vinyon, the plastics bag that the mineral powders such as blending photodegradable aid and calcium carbonate are made, and is also called photodegradation shape pocket.This plastics bag decomposes under the effect of sunlight.Its shortcoming is degradation time because sunshine and climate change are difficult to prediction, thus uncontrollable degradation time.
Current studies in China has gone out a kind of new degradable plastics, its composition be polyvinyl alcohol add starch add again photosensitizers synthesis, polyvinyl alcohol is degraded easier than polyethylene natively, add photosensitizers can accelerate plastics degraded by absorbing sunlight, starch then can promote plastics biodegradable speed in soil.Therefore this novel degradable plastics are more easily degraded relative to front kind, and after its degraded, plastic components resolves into the material of the simple molecular structure such as carbon and water, compares environmental protection.Light, biodegradation plastic have had very large improvement than photodegradation plastic and Biodegradable plastic, having plant-scale photo & bio degradable plastics is up to now in common non-degradable polyolefin plastics, add photodegradable aid (as molysite class photosensitizers) and microbial nutrition agent (as starch, Mierocrystalline cellulose, chitin etc.) miscibility photo & bio degradable plastics.Degradation time: biodegradable plastic is decomposed into carbonic acid gas completely and water needs for a long time, generally speaking in 2-12 month.Goods lose original shape become little fragment can think degraded substantially complete.
Although at present relevant degradative plastics research and report more, many particular problems can not solve, the jaundice of degradable plastic bag color and luster dimness, and transparency is low, to the sense that people's one is clean and ugly not, uses worried.Degradable plastic bag weight capacity is low in addition, can not meet the requirement of client's many dresses thing and Reusability; Amyloid degradative plastics water tolerance is all bad, and wet tenacity is poor, and a chance water then mechanical property falls greatly.
