Embodiment Construction

[0014] A preparation method of chitosan-silicon dioxide modified puffed feather powder composite material, comprising the following steps:

[0015] (1) Mix 0.5 parts by weight of tetraethyl orthosilicate, 0.5 parts by weight of hydrochloric acid solution with a mass fraction of 0.05%, and 2 parts by weight of absolute ethanol, and then stir at 40°C for 0.5h to obtain a silica sol. Mix 0.2 parts by weight Add chitosan to 10 parts by weight of acetic acid solution, stir and dissolve evenly, then slowly add the silica sol dropwise and stir at 40-50°C for 0.5-1h, and obtain a feather modification solution after cooling;

[0016] (2) 100 parts by weight of poultry feathers are degreased, dedusted, washed, and dried, and then added to the feather modification solution prepared in step (1) to stir evenly. After standing for 1 hour, add it to an extruder at 195 ° C. puffing, and finally pulverizing evenly to obtain the chitosan-silicon dioxide modified puffed feather powder composite ...

Abstract

The invention discloses a preparation method of a chitosan-silica modified expanded feather meal composite material. Silica sol is obtained by a sol-gel method, added into acetic acid solution of chitosan and uniformly stirred to obtain feather modified liquid, the feather modified liquid is mixed with degreased, dedusted, cleaned and dried poultry feather to obtain materials, the obtained materials are added into an expander for expansion, and finally, the materials are crushed to obtain the chitosan-silica modified expanded feather meal composite material. The chitosan-silica modified expanded feather meal composite material prepared by the preparation method has excellent light, breathable and heat insulation performances, good mechanical performance and anti-bacterial mildew-proof performances, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of feather processing, in particular to a preparation method of a chitosan-silicon dioxide modified puffed feather powder composite material. Background technique [0002] With the rapid development of modern agriculture, large-scale poultry farming produces a large amount of waste, most of which are feather waste. At present, most of the treatment of feather waste in my country is to make feather meal and use it as feed directly. The resource utilization rate and utilization value are not high, and it also brings local environmental pollution and affects people's living environment. Therefore, how to improve the utilization value of feathers and expand the application range of feathers has become a key research topic. Puffed feather powder is a material obtained by puffing feather powder. It has a porous and loose fiber structure. Heat and other characteristics, the development value is high. However, th...
