Description

A kind of carboxymethyl chitosan-starch-novolac epoxy resin blending whole degrading film and its Preparation method
Technical field
The present invention relates to plastic sheeting technical field, specifically a kind of carboxymethyl chitosan-starch-novolac epoxy resin is common Mix up degradable film and preparation method thereof.
Background technology
In recent years, it is on the rise, causes global wide because waste plastic is difficult to degraded " white pollution " that brings General concern, countries in the world have put into effect limitation or have prohibitted the use of the relevant laws and regulations of non-degradable plastic packing article successively.On the other hand, by In manufacture conventional plastic raw material oil be non-renewable resources, with the mankind a large amount of use will exhaustion, thus development with Renewable resource is raw material, degradable environment-friendly plastic is extremely urgent.
The focus of countries in the world research is turned into using biodegradable starch material to prepare degradable packaging film.But Be starch while plastics degradability is improved, on the one hand can cause the decline of its physical and mechanical properties, make its processing tired Difficulty, on the other hand also have that hydrophily is too strong, the compatibility between most of resins for universal use is very poor, cause made of film power Learn performance to decline to a great extent, block-water performance is poor, so as to hinder extensive use of the starch plastic during industrialization promotion.Phenolic aldehyde Epoxy resin is a kind of widely used high molecular polymer, and performance contains substantial amounts of polar group between plastics and rubber Group's hydroxyl, toxicity is very low, and molecular chain structure is symmetrically regular, has unique strong adherence, epithelium pliability, flatness, resistance to Oiliness, solvent resistance, protecting colloid, gas barrier performance and the specially treated water resistance having, while also have certain Biological degradability, water and carbon dioxide can be resolved under the conditions of having in wet environment existing for bacterium in 6 months completely, be Biodegradable Materials, but it is higher to degraded environmental requirement in degradation process, degradation speed is still seemed relatively slow.
