Description
Technical field
The present invention relates to plastic sheeting technical field, specifically a kind of that starch-novolac epoxy resin is blended degradable is closely knit
Bag and preparation method thereof.
Background technology
In recent years, owing to waste plastic " white pollution " brought that be difficult to degrade is on the rise, cause global extensively
General concern, countries in the world have put into effect the relevant laws and regulations limiting or prohibitting the use of non-degradable plastic packing article successively.On the other hand, by
Non-renewable resources in manufacturing the raw material oil of conventional plastic, along with a large amount of use of the mankind will be exhausted, thus development with
Renewable resource is that raw material, degradable environmental friendliness plastic are extremely urgent.
Biodegradable starch material is utilized to become the focus of countries in the world research to prepare degradable packaging film.But
It is starch while improving plastics degradability, on the one hand can cause the decline of its physical and mechanical properties so that it is processing is tired
Difficulty, on the other hand there is also hydrophilic too strong, and the compatibility between major part resins for universal use is very poor, causes the thin film power made
Performance declines to a great extent, and block-water performance is poor, thus hinders the starch plastic extensive application during industrialization promotion.Phenolic aldehyde
Epoxy resin is a kind of broad-spectrum high molecular polymer, and performance is between plastics and rubber, containing substantial amounts of polar group
Group's hydroxyl, toxicity is the lowest, and molecular chain structure symmetry is regular, has the strong adherence of uniqueness, epithelium pliability, flatness, resistance to
Oiliness, solvent resistance, protecting colloid, gas barrier performance and the specially treated resistance to water having, the most also have certain
Biological degradability, with the presence of water and carbon dioxide can be resolved under conditions of antibacterial 6 months completely in wet environment, be
Biodegradable Materials, but higher to degraded environmental requirement in degradation process, make degradation speed still seem relatively slow.
Boehmeria is the traditional fibre crop of great distinct Chinese characteristics, and China's long-term ramie planting area reaches 200,000 hectares of left sides
The right side, in addition to ramie phloem extracts as textile product, Boehmeria boon is seldom utilized.Boehmeria boon utilization rate is low, place
The problems such as reason is difficult are always governments at all levels and relevant department's question of common concern, are also peasant's extremely concerns.Boehmeria
Bone, as the by-product of the large-scale production processing of Boehmeria industry, is important living resources, wherein rich cellulose, half fiber
Element, its content of cellulose deciduous species similar with fibre morphology, the most preferable plant fiber tableware prepare raw material, and
To its most efficient exploitation for improving Boehmeria comprehensive value, promoting that Boehmeria industry development is the most significant.
Summary of the invention
It is an object of the invention to provide a kind of starch-novolac epoxy resin and degradable sealing bag and preparation side thereof are blended
Method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of starch-novolac epoxy resin is blended degradable sealing bag, the component of following portions by weight be prepared from: phenol

Mediate 15 minutes, release cooling, obtain Boehmeria boon and strengthen material；
(3) mixed-powder and 2 that surface hydrophobicity step (1) obtained is modified, 6-di-tert-butyl-4-methy phenol mixes
Close, disperseed 60-90 minute by colloidal mill, be subsequently adding the Boehmeria boon enhancing material that step (2) obtains, made by twin screw
In grain machine, melt extrude pelletize under conditions of controlling temperature 170-180 DEG C, obtain the starch masterbatch of a diameter of 6mm；
(4) starch masterbatch, novolac epoxy resin, tributyl 2-acetylcitrate and remaining residue step (3) obtained
After composition mix homogeneously at normal temperatures, join in single screw extrusion machine, control temperature and enter under the processing temperature of 170-180 DEG C
Row hot-melt extruded Blown Film, last qualitative rolling, packs and get final product.
Beneficial effects of the present invention: product of the present invention is that safe formula produces, and can be used to manufacture food pack etc., produces
When product use, intensity is big, water-fast, oil resistant, durable in use, is advantageously implemented large-scale industrial production simultaneously, it is easy to grasp, just
In popularization, discarded after product under the oxygen-enriched and effect of microorganism can automatic classifying, ultimately generate carbon dioxide and water, ecological
Environmental protection.
