Description

A kind of silkworm feed additive and preparation method for improving mulberry silk intensity and electric conductivity
Technical field
The present invention relates to Silkworm Raise field of feed, more particularly to a kind of mulberry for improving mulberry silk intensity and electric conductivity Additive for feed of silkworm and preparation method.
Background technology
China is the cradle of planting mulberry and breeding silkworm, according to legend the existing history of 5,000 years, silkworm is prevented and cured diseases, science is raised, Had made great progress in terms of development man-made feeds.Mulberry silk, is a kind of natural animal protein fiber, by matured silkworm point Secrete a liquid solidification to form, because it has graceful gloss, magnificent outward appearance, soft feel, good hygroscopicity and breathes freely Property, it is very popular, the title of " human body Second Skin " is have, and the cutin and collagen of mulberry silk and human body are all albumen Matter, structure is very close, and with fabulous human-body biological compatibility, supply falls short of demand for the market demand, in weaving, biological medicine, group The fields such as weaver's journey are all widely used.Therefore mulberry silk is applied to wearable strain sensing by people in research in recent years Device, because the factors such as structural instability, electric conductivity is poor easily occurs in processing procedure in current mulberry silk, the project does not have slowly Progress.So many scholars are directed to being modified the research of domestic silkworm silk, at present, the method that silk and its product are modified mainly has thing Modified, chemical modification and blending and modifying etc. are managed, the patent of invention of such as Application No. 201110115064.2 discloses a kind of raising The method and modified silk boiled-off silk line of silk line degradation property, its be under anaerobic, by after degumming silk line carry out γ- X ray irradiation x, the dosage of the irradiation is 50kGy~1000kGy, and the modified silk boiled-off silk line obtained after invention processing has Preferable mechanics and degradation property, are suitable as operation suture thread, nerve trachea, artificial blood vessel or artificial bone etc.;Application No. 201110336674.5 patent of invention discloses a kind of modified silk and preparation method thereof, and the modified silk passes through degumming process And modification and obtain, its fibroin albumen through processing appropriateness it is modified, Protein secondary structure is mainly beta sheet structure, reduction Random coil structure, this structure can be beneficial to preferably combine blood platelet, and then quickly promote thrombosis;Application No. 201610317379.8 invention provides a kind of preparation method for the silk fiber that graphene is modified, by by fibroin film Dissolving prepares the regenerated silk aqueous solution, and it is fine to be mixed with regenerated silk with the chitosan of graphene oxide water solution and low molecule amount Dimension, and in the layer graphene film of surface atomizing one of regenerated silk fiber, the inside and surface of regenerated silk fiber is all added Grapheme material, fundamentally function to silk fiber be modified, assign silk fiber high intensity, conduction, thermally-stabilised Optimize the original characteristic of silk fiber to greatest extent etc. performance, and by optimizing the preparation process of the regenerated silk aqueous solution;But on State these methods and often there are problems that complex procedures, cost are higher, pollute, therefore need new method of modifying.
The content of the invention
The invention provides a kind of silkworm feed additive and preparation method for improving mulberry silk intensity and electric conductivity, overcome at present There is higher, pollution environment of complex procedures, cost etc. in the method for modifying of physics, chemistry and blending that silk and its product are used etc. Defect there is provided one kind it is easy to operate, modifying process is completed in silkworm body, and stability and controllability are ensured, it is possible to increase mulberry The mulberry silk feed addictive of silk intensity and electric conductivity.
In order to reach above-mentioned purpose, the present invention uses following concrete technical scheme:One kind improves mulberry silk intensity and led Electrical silkworm feed additive, be educated using activated carbon and diatom as primary raw material through diatom water planting, diatom water process, activated carbon Processing, proportioning step are prepared from.
Present invention also offers above-mentioned raising mulberry silk intensity and the preparation method of the silkworm feed additive of electric conductivity, tool Body comprises the following steps:
