It is not easy to dehydration.High water-absorption fiber has the following advantages that [(1) surface area is big, and absorption speed is fast；(2) gel does not flow after absorbing water,
It can keep the intensity and integrality of water-absorption fiber:(3) manufacture craft of amenities is simplified；(4) general fiber can be used
Processing equipment makes product with other fiber blends.Since high water-absorption fiber has lot of advantages, in agriculture, woods, gardening, day
The sector applications such as articles for use chemical industry, building material industry, health care and communications and transportation have a extensive future.
Ni Jianping exists《The preparation and application of fiber and hydrogel composite material》Using acrylic acid as monomer in one text, N, N '
One the third phthalein of di-2-ethylhexylphosphine oxide amine is crosslinking agent, adds a small amount of microcrystalline cellulose, ultraviolet light-initiated to prepare polyacrylic acid/microcrystalline cellulose
Composite high-water-absorptivresin resin, crushes, the super absorbent resin powder more than 120 mesh after screening is prepared by being laminated complex technique
The high-hydroscopicity paper base material of similar " sandwich " structure, soaking effect is significantly but due to compound preparing high water adsorbing paper being laminated
During, it is necessary to coating binder on page, in the drying process, the migration that the change of coating structure and adhesive occur
It can influence the intensity of page.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, strengthens moisture-keeping functions, reduces cost, simplifies technique,
A kind of preparation method of biodegradation type moisturizing vegetables packaging fibrous paper is provided.
The present invention is achieved by the following technical solutions：
A kind of preparation method of biodegradation type moisturizing vegetables packaging fibrous paper, comprises the following steps：

Enzyme, under the conditions of 40-50 DEG C pre-process 2-3 it is small when, then 80-90 DEG C handle 2-3 it is small when after, be cooled to room temperature immersion 4-5
After it, high-speed stirred obtains slurry into suede, stand-by；
(2) 40-60 DEG C during 12-18 weight starch is mixed with 100-120 mass concentrations for 2-5% sodium hydroxide solutions
Dissolve by heating completely, then add 1-2 parts by weight succinic anhydrides, the ethanol solution of 1-2 parts by weight silane coupling agents, 50-
80 DEG C of heating water baths, when reaction 10-12 is small, obtain modified starch, stand-by
(3) add degree of neutralization to mixture obtained by step (2) and reach 60-80% acrylic monomers and 5-10 parts by weight bumps
Rod soil, until after when soaking at room temperature ageing 24-48 is small after mixing, it is stand-by；
(4) by mixed solution mixed at high speed obtained by the slurry obtained by step (1) and step (3) it is uniform after, rise temperature is extremely
At 80-90 DEG C, 0.1-0.5 parts by weight is added into solution N, N '-methylene-bisacrylamide that mass concentration is 1-5%
With 1-2 parts by weight initiator potassium persulfates, when stirring polymerisation 24-36 is small, starch-polyacrylic acid-attapulgite mixing is obtained
Slurry, be copied into body paper, after being dried in vacuo, drying both biodegradation type moisturizing vegetables packaging fiber
Paper.
The fiber is bamboo fibre, the one or more in reed fiber, awns stalk fiber, wheat straw fiber, rice-straw fibre.
The starch is cornstarch, tapioca or the one or more of of farina mix.
The attapulgite is 200-400 mesh.
A kind of preparation method of biodegradation type moisturizing vegetables packaging fibrous paper, it is characterised in that by claim 1-4
The method is prepared.
It is an advantage of the invention that：
(1) present invention, at room temperature by continuing to degrade in water, changes fiber by fiber after cellulase degradation
Form, breaks into slurry afterwards, increases fiber fluffy degree, paper pulp is had good mechanical strength and gas permeability, starch is put into
Succinic anhydride, modification in the ethanol solution of silane coupling agent mixed preparing, introduces organic group on starch surface, changes
The combination degree of kind starch and other boundaries, while succinic anhydride can improve the adhesiveness of fiber surface.
(2) after being mixed after attapulgite and acrylic acid are compound with modified starch, slight implode occurs for addition crosslinking agent, and third
Crosslinking between olefin(e) acid and starch, while the carboxyl of acrylic acid introducing and the hydroxyl of fiber react, and are combined more with fiber
Fully, moisture-keeping functions are improved, enhance the mechanical properties such as tensile strength, permanent deformation and tearing strength, and reduce life
Cost is produced, simplifies technique, the material prepared can carry out biodegradation using starch to be carbon-based.
