Abstract
The invention relates to a preparation method for a eucommia ulmoides gum, in particular to a method and a device for extracting the eucommia ulmoides gum from insect excrement of an insect eating eucommia ulmoides. The method adopts the following technical scheme that the method comprises the steps as follows: drying, extracting, filtering and drying. Based on a characteristic that dictyoploca japonica butler larvae like to eat leaves of the eucommia ulmoides and natural eucommia ulmoides gum is difficult to metabolize in living organisms, the eucommia ulmoides gum is extracted from excrement of dictyoploca japonica butler larvae, so that eucommia ulmoides resources can be utilized and protected to the greatest extent. The obtained extract is high in purity, the gum productive rate is higher, the color and the luster of the extracted eucommia ulmoides gum are good, the production steps are simple, the usage amount of a solvent is small, and the risk level is low. Steps of stewing, fermenting and the like in the conventional extraction mode are avoided, the gum productive rate is greatly increased, the extraction cost is saved, and the extracted eucommia ulmoides gum is greatly improved in stretchability, toughness and elasticity.
Description
Technical field
The present invention relates to the preparation method of gutta-percha, relate in particular to a kind of method and device that utilizes the insect worm excrement extraction gutta-percha of the edible bark of eucommia.
Background technology
Today that the natural gum resource provisioning is nervous in the world, price soars, increasing income and decreasing expenditure becomes the realistic problem that global rubber industry faces.How to enlarge the rubber raw materials extent of supply, become the new focus of industry.The tradition medicinal plant bark of eucommia becomes second kind of natural gum resource except rubber tree, and the bark of eucommia is Chinese distinctive famous and precious economic tree, also is the widest important collagen plant of the scope of application in the world.
Gutta-percha is the natural macromolecular material that originates from gutta-percha tree, and is identical with the chemical ingredients of para rubber, and just microtexture is different.Both are isomerss.Gutta-percha is a using trans-polyisoprene, and para rubber is a cis-polyisoprene.World rubber industry was born over more than 100 year.Para rubber is called tree elastomer by custom because of having elasticity at rubber circle, and is used widely.And gutta-percha is the potential substitute of natural gum, and China be if can produce gutta-percha in enormous quantities, and gutta-percha is applied to automobile, plane tyre exploitation; Comply with in the world with anti-form-1,4 structure rubbers are main, the development long lifetime; Safety, the trend of energy-conservation " green tire " will provide new for the poor China of tree elastomer; The competent reserve glue of steady sources kind; Promote China's rubber industry to develop rapidly and healthily, also possibly change the general layout that international tree elastomer distributes, promote development of world rubber industry.
The utilization history of Folium Eucommiae is not long; But the exploitation of the breakthrough of the peculiar gutta-percha processing technology of eucommia health care article and China and Folium Eucommiae feed brings new hope all can for the full use of the bark of eucommia in the world; Especially after the success of gutta-percha and series product development; Formation that drives the big industry of bark of eucommia comprehensive exploitation and bark of eucommia production are developed healthy and stablely, also can promote improving constantly of bark of eucommia economic benefit simultaneously.
The production base is positioned at domestic Lueyang County, the Qinling Mountains, and this county stops one of base as maximum Du of China, has 1.3 hundred million strains, 580,000 mu of high-quality eucommia resources.Qinling Mountains physical environment richly endowed by nature provides good hotbed for the growth of this rare ancient tree.But,, can cause great destruction to eucommia resource if only rely on bark and other positions to extract natural gutta-percha because the production cycle of gutta-percha tree is long; The ginkgo Io moth is one of a main disease and pest in bark of eucommia vegetative period, and gutta-percha is a kind of white rope, and chemical ingredients is anti--1; The 4-TR 301 has the duplicity of rubber-plastics, is called as second kind of natural gum; Be that accommodation is the widest in the world, the high-quality Jiao Yuan that development potentiality is maximum has bright development prospect.
Summary of the invention
The purpose of invention: for provide a kind of can be for China provides new, the competent reserve glue of steady sources kind and preparation method thereof, this kind method do not influence the growth of the natural bark of eucommia again, and can profoundly probe into the purposes of worm excrement in the preparation gutta-percha.
In order to reach as above purpose, the present invention takes following technical scheme: a kind of method of utilizing the insect worm excrement extraction gutta-percha of the edible bark of eucommia, it is characterized in that, and comprise following steps:
Dry: that the worm excrement is carried out thorough drying;
Lixiviate: adopt sherwood oil or ether that dried worm excrement is carried out once above lixiviate, each extraction time is 1-2 hour;
Filter: immersion liquid is filtered, and wash filter residue with flowing water;
Oven dry: filter residue is dried under 70-75 ℃ of condition.
The further technical scheme of the present invention is, also comprises following steps before the said step drying, and water-bath and washing, said water-bath and washing are meant that with the worm excrement with 75 ℃ of water-baths 15 minutes, flowing water washed then.
The further technical scheme of the present invention is that the insect of said worm excrement is the larva of ginkgo Io moth (Dictyoploca japonica Butler).
The further technical scheme of the present invention is, said ginkgo Io moth larva worm age is 3-5 age.
The further technical scheme of the present invention is that stating the lixiviate number of times is three times, and said extraction time is 2 hours.
The further technical scheme of the present invention is, the fecula stool of collecting is placed in the screen device carried out water-bath and washing.
The purposes of the worm excrement of ginkgo Io moth (Dictyoploca japonica Butler) in the preparation gutta-percha.
Be used for the worm excrement and prepare the device that gutta-percha technology is collected the worm excrement, it is characterized in that, comprise treating pond, more than one operating walk way is arranged on the treating pond, said more than one operating walk way all includes the bottom of sieve aperture.
Adopt as above the present invention of technical scheme; Utilize ginkgo Io moth larva happiness food Folium Eucommiae and natural gutta-percha to be difficult for this characteristic of metabolism in vivo; From the ight soil of ginkgo Io moth larva, extract gutta-percha, can utilize and protect eucommia resource to greatest extent.
Since the young leaflet tablet of the larva of the ginkgo Io moth happiness food bark of eucommia, and the gutta-percha content of bark of eucommia young leaflet tablet is relatively low, therefore need carry out acclimatization culture to the kind of ginkgo Io moth, increases the food leaf amount of larva, improves rate of gum output.
Gutta-percha process for extracting of the present invention, the extract purity of gained is high, and product glue rate is also higher, and the gutta-percha color and luster of separating out is good, and production process is simple, and solvent load is little, and is dangerous little.
The polymerization of gutta-percha is under the effect of enzyme, to carry out; After the digestion and absorption of Folium Eucommiae through ginkgo Io moth larva; From the ight soil of output, extract gutta-percha, avoided the link such as boiling, fermentation in traditional extracting mode, improved product glue rate greatly; And practiced thrift extraction cost, and the gutta-percha that proposes also has greatly improved in the quality aspect stretchiness, toughness, the elasticity.
