Abstract
Composite porous and preparation method thereof the invention discloses a kind of improved salix monogolica konjaku, step is as follows：Salix monogolica is removed the peel, crushed, is sieved, is dried, is cooled down, purify after obtain salix cellulose；Salix cellulose is modified using sodium metaperiodate；Use PAMAM modified konjakus；After sodium metaperiodate modification salix cellulose, PAMAM modified konjakus and pore-foaming agent are well mixed, 24h is reacted under normal temperature, is cleaned repeatedly with deionized water, it is composite porous that drying obtains improved salix monogolica konjaku.The present invention uses konjaku, salix monogolica to have the advantages that raw material is sufficient, cheap as raw material, have important application value in fields such as sorbing material, biomaterials.
Description
Technical field
The present invention relates to a kind of improved salix monogolica-konjaku is composite porous, belong to field of compound material.
Background technology
For a long time, cellulose is always weaving, the key industry raw material of papermaking, with its recyclability, biodegradable
Property and cost advantage are increasingly subject to the attention of people, in medicine control, release tech, immobilization technology, biology sensor, membrane material
Material, performance chemicalses and additive etc. show good development prospect.Reduction and oil, natural gas due to arable land etc.
The increasingly depleted of fossil resource, the yield of synthetic fibers will be restricted more and more.And native cellulose is as a kind of
Green, environmentally friendly, reproducible resource, obtain a unprecedented opportunity to develop.
Salix monogolica is the desert plant that a kind of only a few can be grown in salt-soda soil.Its sprout is yellow, in leaf is linear or line
Shape lanceolar, branch, which is grown thickly, is not afraid of husky pressure, and well developed root system, rudiment power is strong, is desert-control tree, be mainly distributed on the Inner Mongol,
The ground such as Hebei, Shanxi, Shaanxi, Gansu, Qinghai, Sichuan.Salix monogolica is one of the first choice of " three Norths shelter-forest ", is not only acted as windproof solid
Effect that is husky, conserving water and soil, improving the ecosystem, maintaining ecological balance etc. that also there is unique function.
Salix monogolica in addition to small part is used for pulping and paper-making, fiberboard and composite plate, burn or lose as yule logs by the overwhelming majority
Abandon, cause the huge wasting of resources.The main chemical compositions of salix monogolica mainly have cellulose, hemicellulose, lignin and ash content, fine
The content of element is tieed up in more than 60-70%, is natural reproducible biomass resource, rationally will produce huge warp using salix monogolica resource
Benefit of helping and ecological benefits.At present, most research all concentrates on the cellulose how extracted in salix monogolica.Beijing Forestry University
Department of chemistry engineering Jiang builds new et al. the influence that have studied steam blasting pretreatment to salix monogolica composition and fibre structure performance（Modernization
Work, 2008,28 (2)）.Agricultural University of the Inner Mongol's material science and School of Art and Design Zhang Bin et al. are using salix cellulose as original
Material, have studied the technique that supercritical ultrasonics technology prepares microfibril（Paper and papermaking, 2014,33 (3)）.Agricultural University of the Inner Mongol's material science
With refined et al. main chemical compositions cellulose, the hemicelluloses that salix monogolica material has been isolated using chemical reagent of School of Art and Design Li Ya
Element（Agricultural University of the Inner Mongol's journal, 2014,35 (1)）.Industry light industry textile industry institute of Qiqihar University is permitted phoenix et al. and utilizes peroxidating
Hydrogen method separates salix monogolica and the cellulose in caragana microphylla mixed material（Chemistry of forest product and industry, 2006,26 (2)）.Zhengzhou University's chemical industry
Salix cellulose is extracted with energy institute Huang star et al. use acid catalysis Ethanol Method（Jiangsu's agriculture science, 2014,42 (3)）.
Konjaku glucomannan（Konjac glucomannan, abbreviation KGM）It is after starch and cellulose, one kind is more
Abundant renewable natural polymer child resource, has biodegradable, and its hydrosol has very high viscosity and multifrequency nature
Such as thickening, gel and film forming performance；And a kind of excellent dietary fiber, available for prevention and treatment hypertension, high fat of blood,
The diseases such as cardiovascular disease, it has also become important food additives and healthy food material.In fields such as chemical industry, environmental protection and oil drillings
Also there is important use（Structural chemistry, 2003,06:633-642）.
Using acidified modified, alkali modification, grafting, copolymerization and modification, it is cross-linking modified and etherification modified the methods of can improve KGM's
Performance, for example add alkali deacetylate processing KGM, its strain resistant ability enhancing, mechanical property are improved after processing, therefore natural
KGM and its modified product, turn into one of focus of research（Material Leader, 2009,19:32-36）.
, can also be by being mixed with other suitable biopolymers to improve KGM property except chemical modification（Material
Leader, 2009,19:32-36）.Such as Wuhan University of Technology Fan Li Hong konjaku is made after sodium periodate oxidation oxidation konjaku
（OKGM）, utilize its aldehyde radical and hydroxypropyl chitosan（HPCS）On amino crosslinking prepare hydrogel, while by graphene oxide
（GO）Added as additive in hydrogel and obtain hydroxypropyl chitosan/oxidized konjaku/graphene oxide hydrogel（Wuhan University
Journal (Edition), 2016,04:361-367）.Guangzhou Business School Huang builds the method for just using physical blending, according to KGM:
Silk peptide=1:0,1:2,2:1,0:1 molal weight is molten by quantitative silk peptide in the case of stirring than preparing blending colloidal sol
In deionized water, after being completely dissolved, add quantitative KGM powder, under 45 DEG C of water bath conditions, with 450rmin-1Stirring
1h, blending colloidal sol is prepared（Concentration is 1.2%）（The biological journal in the torrid zone, 2016,04:472-476）.University Of Agriculture and Forestry In Fujian is thanked
Third clearly according to KGM:Fibroin=1:1、1:2、1:3 mass ratio is mixed and stirred for being allowed to well mixed, have studied silk egg
