Abstract
The invention discloses a kind of biodegradable plastics based on Sargassum polysaccharides and preparation method thereof.The main component of biodegradable plastics is as follows: Na-alginate 10 90 parts, carrageenan 10 90 parts, 0.1 10 parts of calcium chloride, ethanol 0 40 parts.This plastic foil preparation method is simple, and product strength is high, and transparency is good, and safety non-toxic, can be as food pack.Comparing existing plastic foil, the product that the present invention is produced also has the advantage of fully biodegradable, has stopped the white pollution that petroleum-based plastics film produces.
Description
Technical field
The present invention relates to a kind of biodegradable plastics based on Sargassum polysaccharides and preparation method thereof, belong to biodegradation material
Material technical field.
Background technology
Owing to petroleum-based plastics goods are difficult to biodegradation, it is stacked and process is a global difficult problem, creates
Substantial amounts of white pollution thing, thus biodegradable plastics is all being greatly developed in countries in the world.Current biodegradable plastics
Mostly formed by biomaterial and petroleum based material such as polyethylene etc. are blended, there is certain biological degradability, but still cannot be complete
Degradable, the problem the most fundamentally solving plastic product white pollution.It is many that the present invention has developed a kind of employing Sargassum
Biodegradable plastics prepared by sugar carrageenan and calcium alginate, it is high that it has intensity, safety non-toxic, fully biodegradable etc.
Advantage, alternative petroleum-based plastics product, stop the generation of white pollution, thus there is wide market prospect.
Summary of the invention
It is an object of the invention to provide a kind of biodegradable plastics based on Sargassum polysaccharides and preparation method thereof, this is moulded
Material membrane preparation method is simple, and product strength is high, and transparency is good, and safety non-toxic, can be as food pack.Compare existing plastics
Film, the product that the present invention is produced also has the advantage of fully biodegradable, has stopped the white that petroleum-based plastics film produces
Pollute.
The present invention is achieved by the following technical solutions:
A kind of biodegradable plastics based on Sargassum polysaccharides, main component includes according to the mass fraction: sodium alginate 10-90
Part, carrageenan 10-90 part.
Described composition the most also includes: calcium chloride 0.1-10 part, ethanol 0-40 part.
Described preparation method comprises the steps:
(1) weigh sodium alginate, carrageenan in proportion, be added to the water, be stirred well to dissolve completely；
(2) solution of gained in step (1) is poured in container, in an oven in 30-80oC toasts 5-72 hour；
(3) calcium chloride of 0.1-10 part is joined in the ethanol of 0-40 part and the water of 50-99.9 part, wiring solution-forming, described part
Number is mass fraction；
(4) calcium chloride solution in step (3) is poured in the container toasted, soak 1-60 minute；
(5) from container carrageenan and calcium alginate composite membrane are taken off out, after naturally drying, i.e. can get hot strength excellent,
Biodegradable plastics film.
The remarkable advantage of the present invention is: carried out by the carrageenan of the calcium alginate of cross-linked network Yu linear structure multiple
Close, one can be formed and partly run through network structure (semi-interpenetrating networks), material can be obviously enhanced
Intensity.Compared with existing petroleum-based plastics, this novel plastic can be degradable by biology.And owing to its intensity is high, safety
The feature such as nontoxic, can use as food pack etc., and production process is simple, has wide market prospect.
Accompanying drawing explanation
Fig. 1 is Product Rendering.
Detailed description of the invention
Below in conjunction with present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.Base
Embodiment in the present invention, that those of ordinary skill in the art are obtained under not making creative work premise thus its
His embodiment, broadly falls into the scope of protection of the invention.
Embodiment 1
A kind of based on Sargassum polysaccharides carrageenan with the biodegradable plastics of calcium alginate, by 40 parts of sodium alginates, 60 parts of OK a karaoke clubs
Glue is soluble in water, is configured to the aqueous solution that total mass concentration is 1%, pours in container, in an oven in 50oDry 24 hours under C.
Then the solution that 1 part of calcium chloride of configuration, 20 parts of ethanol and 79 parts of water are formed, pours in the container toasted, soaks 30 minutes, take off
Film, dries naturally, i.e. can get high intensity and the good biodegradable plastics film of transparency, and described number is mass fraction.
Being placed on film by 500 g counterweights, this film can bear bigger pressure and the most damaged, and effect is as it is shown in figure 1, demonstrate film-strength
Height, can use as plastic packaging bag.
