Abstract
The invention relates to a method for preparing keratin adhesive by using feathers. The method comprises the following steps of : (1) washing the feathers, drying to obtain clean feathers, shearing the clean feathers, immersing the sheared feathers into a dissolving liquid for dissolving, filtering to remove residues, and obtaining soluble feather keratins; and (2) standing and shaping the soluble feather keratins at the temperature of 15 DEG C-30DEG C to obtain the keratin adhesive. The method is simple in operation and quick in production effect, provides a new feasible scheme for development of the adhesive, improves a utilization ratio of the feathers, provides a new application approach for the feathers, turns waste into wealth and reduces pollution to the environment during burning treatment of the feathers.
Description
Technical field
The invention belongs to the preparation field of glue paste, particularly a kind of method utilizing feather to prepare Keratin sulfate glue paste.
Background technology
1993, Wang Zhenjie utilized feather, hoof tips food nutrition tackiness agent, was by after feather and hoof tips difference acidolysis and alkaline hydrolysis, carried out neutralizing treatment, concentrated, then obtained concentrated solution, packaging final prod after drying.The crude protein of the nutritive glutinous mixture obtained is close to 80%, and other various protein classes enrich, and is to have nutrition, bonding double effects.2005, the triumphant profit of RJ, the people such as DA Rankine, the Keratin sulfate of the S-sulfonation of solubility has been prepared and has been comprised film, fiber, foam and adhesive material by utilization, the method that wherein adhesive material adopts is: obtain keratein(e) or keratein(e) peptide solution with reductive agent (mercaptan or phosphorus), and it is mixed with S-sulfonate keratin solution, result in formation of cross-linked network structure, become tackiness agent.2007, Manfred Drank and Robert Wimmer thinks and only Keratin sulfate just can be utilized to form available model by the change of temperature and pressure, and any pharmaceutical chemicals need not be added, also think that the bio-based materials made by this method also can be applied to numerous aspects as a kind of tackiness agent simultaneously.2010, Zhenyu Du and X.B Sun thinks in industry of artificial boards, urea aldehyde as main adhesive type has very large drawback because of the formaldehyde content of its superelevation and burst size, they attempt the reaction by being polymerized with urea aldehyde by Keratin sulfate, are optimized urea aldehyde, and they are by adjustment mol ratio, add Keratin sulfate sequence and increase the technology such as Keratin sulfate quantity, finally obtain the tackiness agent of low toxicity, and because keratic utilization, greatly reduce the price of this material.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method utilizing feather to prepare Keratin sulfate glue paste, discarded poultry feather is degraded recovery by the present invention under certain condition, obtain feather keratin solution and feather keratin cross-linking agent two kinds of form material with certain viscosity, be processed as glue paste further.This degraded solutions and cross-linking agent can adhesion characteristic obvious, and process the method green non-pollution of material.
A kind of method utilizing feather to prepare Keratin sulfate glue paste of the present invention, comprising:
(1) feather is clean, drying obtains clean feather, is dipped in lysate and dissolves, cross and filter to remove residue, obtain the feather keratin of solubility after being shredded by clean feather;
(2) the solubility feather angle egg obtained is left standstill shaping at 15 DEG C ~ 30 DEG C, obtain Keratin sulfate glue paste.
In described step (1), the mass volume ratio of clean feather and lysate is 1 ~ 10g:10 ~ 50ml.
In described step (1), lysate is the mixing solutions of 2M ~ 10M urea, 0.05M ~ 1M Sodium Metabisulfite and 0.05M ~ 1M sodium lauryl sulphate (SDS).
Be dissolved as in bath temperature 70 DEG C ~ 120 DEG C in described step (1), dissolve 15min ~ 30min with the concussion of the speed of 80 ~ 120r/min.
Leaving standstill shaping temperature in described step (2) is 20 DEG C ~ 25 DEG C Keratin sulfate being formed with viscosity.
In described step (2), Keratin sulfate glue paste is made up of keratin solution and Keratin sulfate cross-linking agent.
In described step (2), the range of viscosities of Keratin sulfate glue paste is 40-400000mPa.s.
beneficial effect
(1) preparation method of the present invention can realize reluctant bird waste feathers to reclaim to dissolve recycling;
(2) the inventive method is simple and quick, turns waste into wealth;
(3) product viscosity that prepared by the present invention can reach the requirement of Yaoing Qiu≤1200mPa.s of light industry standard QBQ/T1961-2011 office glue medium viscosity;
(4) product that prepared by the present invention is poisoned little, achieves economic benefit, and reaches the object of protection of the environment.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
