Description
Technical field
The present invention relates to a kind of Degradable plastic film, particularly a kind of starch-based fiber element Degradable plastic film.
Background technology
Along with the fast development of China's economy, plastics industry scale is also rapidly expanded, and plastic prod is applied to increasing industry.2010, world's plastics consumption was estimated as 3,128 hundred million t, and Chinese Plastics consumption is estimated also just will more than 5,600 ten thousand t.Plastic prod is industrial, agriculture and daily life provides conveniently, and also create a large amount of waste, these wastes exist in solid form, and its source mostly is the Phthalates such as packing bag, beverage bottle, agricultural mulching simultaneously.These volume of waste are large, the resolving time is very long, and degrade in physical environment very difficult, someone estimates about needs 200 years ~ 1,000,000 years.The treatment process (landfill, burning and recycling) of plastic refuse is difficult to fundamentally to solve " white pollution " that plastic garbage brings, and can not meet the needs that people's growing " environmental friendliness " realize.Further, plastics are petroleum-based products, and the fluctuation of oil price also causes the instability of plastic prod price.The minimizing day by day of current oil resource, the sustainable development of plastics industry must be restricted.
Due to degradative plastics have raw material sources extensively, degradable, the advantage such as free from environmental pollution, therefore increasing investigator starts to pay close attention to degradation material.The main purpose of exploitation degradative plastics is the problem of environmental pollution brought for solving plastic refuse.It under particular circumstances, can be degraded to carbonic acid gas and moisture, does not give environment.
The kind of degradative plastics is very many, divides, also have multiple different kind according to its degraded type.But modal degradable plastics is mainly photodegradable plastics and biodegradable plastic two class.Degradable plastics developed through decades, and biodegradable plastic becomes its principal mode.And in biodegradable plastic, starch plastics accounts for most of degradable plastics.Starch is a kind of natural high moleculer eompound, can be possessed certain plasticity by molecular modification, is therefore regarded as one of research object of degradation material field most potentiality.Starch-based, biodegradable plastics common are starch-filled plastic, full-starch plastic and some take starch as the biochemical synthetic polymer of raw material.
But be also faced with some problems in Starch-base Degradable Plastic field: (1) use properties.The mechanical property of starch-based material and conventional plastic also have larger gap, and especially cause mechanical properties decrease after water suction, starch content is larger, and mechanical properties decrease is more obvious.(2) price.Though the obtained degradative plastics mechanical property of chemical synthesis comparatively starch-filled plastic and full-starch plastic good, its complex manufacturing, production cost is higher, can only be applied to pharmaceutical field at present.(3) degradation property.Degradative plastics of a great variety, does not have clear and definite regulation for its degradation property, and product degraded accuracy affects comparatively large by environment for use, degraded accuracy is difficult to control.(4) raw material sources.Starch-base Degradable Plastic uses the starch of grain-production as raw material, occurs that industry strives conflicting of grain with people.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, the Degradable plastic film that a kind of good mechanical properties, degradation speed are fast, raw material sources are extensive, cheap is provided.
In order to realize above goal of the invention, north is invented by the following technical solutions: a kind of starch-based fiber element Degradable plastic film, is made up of the raw material of following mass parts: starch 20 ~ 30 parts; Polyvinyl alcohol 15 ~ 20 parts; 10 ~ 20 parts, cotton fibre; Glacial acetic acid 5 ~ 10 parts; Acetic anhydride 5 ~ 10 parts; Catalyzer 0.1 ~ 0.5 part; Linking agent 2 ~ 5 parts; Glycerine 3 ~ 6 parts; Oxalic dialdehyde 2 ~ 5 parts.
Described starch adopts W-Gum, wheat starch, Starch rice, sweet potato starch or yam starch.
Described catalyzer is the vitriol oil.
Described linking agent is tributyl citrate.
Starch can adopt W-Gum, wheat starch, Starch rice, sweet potato starch or yam starch, wide material sources, and price is lower.Polyvinyl alcohol can improve the mechanical property of degradable plastics as toughener.Cellulose acetate made by employing cotton fibre and starch is cross-linked, and make Degradable plastic film, linking agent is tributyl citrate, and catalyzer is the vitriol oil.
Major advantage of the present invention and beneficial effect are:
(1) because native starch is cheap, wide material sources, the Degradable plastic film of preparation has higher economic worth and social value;
(2) adopt cellulose acetate and starch to be cross-linked, obtained Degradable plastic film good mechanical performance, degradation speed is fast;
(3) degradable plastics membrane preparation method is simple, easy handling.
