Abstract
A kind of method utilizing discarded chicken feather to prepare environment-friendly adhesive, by chicken feather respectively with after the cleaning of suds, 5% aqueous sodium hydroxide solution and distilled water, dry in baking oven, pulverize, taking dry pulverizing chicken feather adds in reaction vessel, adds aqueous hydrochloric acid, stirring reaction, filter, remove wherein insolubles; Then heat up and distill out portion of water, obtaining solid content is the solution of 35 ~ 45%, the temperature of reaction system is down to 45 DEG C, add the epoxy chloropropane of dry chicken feather quality 10%, continue stirring reaction after 1.5 hours, discharging, the chicken feather tackiness agent that availability is excellent, the tensile shear strength of this tackiness agent can reach 13.1 ~ 13.8MPa, and simple to operate, is easy to the realization of suitability for industrialized production.
Description
Technical field
The invention belongs to technical field of adhesive preparation, be specifically related to a kind of method utilizing discarded chicken feather to prepare environment-friendly adhesive.
Background technology
China's macro rearing chicken stock number increase is very fast, and chicken feather output is considerable.But due to domestic chicken feather collection aspect existing problems, a big chunk chicken feather is all treated as rubbish and has been processed, and causes certain pollution, add environmental pressure to environment.Chicken feather contains Keratin sulfate up to more than 85%, and is rich in 18 seed amino acids and multi mineral prime element, is valuable natural resource.Traditionally, chicken feather is generally used to manufacture warm-up, artwork or Shuttlecock etc.The utilization ratio of this mode chicken feather is low, and the most chicken feather of generation goes out of use, and does not realize the comprehensive utilization of chicken feather.In recent years, the comprehensive utilization of people to chicken feather proposes new thinking, mainly contains: 1) chicken feather fibers makes hydrogen storage medium after charing; 2) material of air filter paper is manufactured; 3) the high strength synthetic materials of light-duty densification is produced; 4) chicken feather fibers is weaved cotton cloth the clothes made.But these directions are all in initial stage development, the commodity with practical value cannot be changed into and produce economic benefit.
Chicken feather main component is Keratin sulfate, and this Keratin sulfate can further by acid or alkaline degradation.The tackiness agent of the preparation environment-friendly type that this character of chicken feather can be used.Along with the development of China's modernization construction process, tackiness agent demand sharply increases, and conventional urea-formaldehyde resin adhesive is owing to can discharge virulent formaldehyde gas gradually, and therefore, the cheap environment-friendly adhesive of development of new has great importance.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of method utilizing discarded chicken feather to prepare environment-friendly adhesive, simple to operate, be easy to the realization of suitability for industrialized production.
In order to achieve the above object, the technical scheme that the present invention takes is:
Utilize discarded chicken feather to prepare a method for environment-friendly adhesive, comprise the following steps:
By chicken feather respectively with after the cleaning of suds, 5% aqueous sodium hydroxide solution and distilled water, dry in 50 DEG C of baking ovens, then pulverize, taking dry pulverizing chicken feather adds in reaction vessel, add the aqueous hydrochloric acid of the 5mol/L of 5 ~ 8 times amount, stirring reaction 0.8h at the temperature of 70 DEG C, filters, removes wherein insolubles; Then be warming up to 90 DEG C and distill out portion of water, obtaining solid content is the solution of 35 ~ 45%, and the temperature of reaction system is down to 45 DEG C, add the epoxy chloropropane of dry chicken feather quality 10%, continue stirring reaction after 1.5 hours, discharging, the chicken feather tackiness agent that availability is excellent.
The tensile shear strength of described chicken feather tackiness agent is 13.1 ~ 13.8MPa, and the tensile shear strength 8MPa of more traditional bone glue adhesive has higher bonding strength.
Tool of the present invention has the following advantages:
1, the present invention is the comprehensive utilization of discarded chicken feather, meets sustainable development and sees, and is the environmental development policy of country, the encouragement category of policy.
2, tackiness agent that the present invention obtains is environment-friendly material, and bio-toxicity is low, to operator ' s health without harm.
3, the present invention proposes the high degraded means of a kind of chicken feather degradation efficiency, and have found suitable linking agent, reduce operation sequence, enhance productivity, reach the object turned waste into wealth.
4, the present invention proposes a kind of novel tackiness agent, this tackiness agent has excellent stability, low temperature resistant high-temperature behavior.
