Abstract
The invention discloses a kind of preparation method of styrene-grafted modified collagen albumen sulfonated cellulose composite material, oxidation sulfonation modifying first is carried out to microcrystalline cellulose with sodium metaperiodate, sodium hydrogensulfite, then add graft reaction in collagen solution and obtain collagen sulfonated cellulose compound, then styrene-grafted modified collagen albumen sulfonated cellulose composite material is obtained with vinyl monomer graft polymerization.The composite material that the present invention obtains has excellent water-fast, weather resistance and mechanical property, and durability is good, has effectively expanded the use scope of collagen material.
Description
Technical field
The present invention relates to macromolecule chemical material technical field, more particularly to a kind of styrene-grafted modified collagen albumen-
The preparation method of sulfonated cellulose composite material.
Background technology
Collagen is a kind of natural macromolecular material, has unique filamentary structure and good biological degradability,
The performances such as also good fillibility, covering, film forming, the raw material as a variety of industries such as process hides, papermaking, medicine, daily use chemicals
Or auxiliary agent, application range are quite varied.In the discarded object of leather industry, the content of protein is more than 30%, and wherein glue
Former albumen accounts for more than the 90% of albumen quality.Collagen is refined and to it for raw material with the inferior cladding of process hides, tailing etc.
Comprehensive development and utilization is carried out, can not only be reduced environmental pollution, and it is with good economic efficiency, enjoy people to pay close attention to.So
And single collagen in performance there are many deficiencies, it is low intolerant to wet rubbing, water resistance as hygroscopicity is big, and quality is crisp
Firmly, easy fracture, bad mechanical property, is much limited in practical applications.Therefore, to improve the performance of collagen, expand
The use scope of collagen material, it is also necessary to further research.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, there is provided one kind has excellent mechanical property and water resistance concurrently
Styrene-grafted modified collagen albumen-sulfonated cellulose composite material preparation method.
The present invention is achieved by the following technical solutions：
A kind of preparation method of styrene-grafted modified collagen albumen-sulfonated cellulose composite material, comprises the following steps：
（1）First 1-5 parts by weight microcrystalline cellulose is added in 20-40 parts by weight sodium periodate solutions and is aoxidized in 30-50 DEG C of lucifuge
2-4h is reacted, 20-40 parts by weight solution of sodium bisulfite is added after obtained oxidation microcrystalline cellulose is washed with water in 60-
80 DEG C of sulfonation 2-4h, add 80-100 parts by weight water and are uniformly dispersed, obtain sulfonation microcrystalline cellulose suspension after being washed with water again；
（2）First 2-8 parts by weight collagens are dissolved in 40-60 parts by weight water, then add 20-40 parts by weight steps（1）
The sulfonation microcrystalline cellulose suspension is stirred reaction, obtains collagen-sulfonated cellulose complex liquid；
（3）0.5-1 parts by weight of styrene is added into 100-120 parts by weight steps（2）Collagen-the sulfonated cellulose is compound
It is uniformly mixed in liquid, adds 0.05-0.01 parts by weight potassium peroxydisulfate in 60-70 DEG C of reaction 3-5h after being passed through nitrogen, obtained after cooling
To styrene-grafted modified collagen albumen-sulfonated cellulose composite material.
The mass concentration of the sodium periodate solution is 3-5g/L.
The mass concentration of the solution of sodium bisulfite is 15-20g/L.
The step（2）It is middle stirring reaction condition be：50-60 DEG C of whipping temp, mixing time 12-24h.
A kind of styrene-grafted modified collagen albumen-sulfonated cellulose composite material, is obtained by the preparation method.
It is an advantage of the invention that：
The present invention first carries out microcrystalline cellulose with sodium metaperiodate, sodium hydrogensulfite to aoxidize-sulfonation modifying, then adds collagen egg
Graft reaction obtains collagen-sulfonated cellulose compound in white solution, then is obtained with vinyl monomer graft polymerization
To styrene-grafted modified collagen albumen-sulfonated cellulose composite material.Pass through sulfonation microcrystalline cellulose and the height of collagen
Effect, which combines, assigns composite material good toughness, and the good water resistance of composite material, corrosion resistance are assigned by graft phenylethene
And weatherability, so as to get composite material there is excellent water-fast, weather resistance and mechanical property, durability is good, effectively expands
The use scope of collagen material.
Embodiment
