DEG C, 300r/min be stirred, the glycerol for adding cassava oxidized starch quality 60 ~ 70% is stirred, and homogeneous obtains homogenizing fluid；
(3) it takes homogenizing fluid 4 ~ 10:3 in mass ratio ~ 5 that soybean protein isolate is added, is stirred 20 ~ 30min, adds homogenizing fluid
The sodium alginate of quality 20 ~ 30%, obtains mixture, takes mixture 2 ~ 4:8 in mass ratio ~ 11 that distilled water is added, adds mixture
The glycerol of quality 5 ~ 10% adjusts pH to 7 ~ 8, is warming up to 60 ~ 80 DEG C and is stirred, and filters, and takes filter vacuum to deaerate to get anti-
Finish.
Processing condition in the step (1) are as follows: in 5 ~ 8min of 18000r/min homogeneous.
The preparation method of the antibacterial activity agent, includes the following steps:
It takes chitosan 1 ~ 3:40 in mass ratio ~ 50 that the acetic acid that mass fraction is 0.5% is added, obtains mixed liquor a, taken in 20 ~ 25 DEG C mixed
It closes liquid a 3 ~ 5:5 in mass ratio ~ 8 and the xanthan gum solution that mass fraction is 1% is added dropwise, adjust pH to 5 ~ 6, add mixed liquor a
The Tween-80 of quality 1 ~ 3% and the nisin of mixed liquor a mass 8 ~ 15% are stirred, and centrifugation takes precipitating drying, i.e.,
Obtain antibacterial activity agent.

The growth and breeding of bacterium and gemma have inhibiting effect, antibiotic layer are formed on greaseproof surface, so that the antibacterial effect of greaseproof mentions
It rises；
(2) tapioca is added through octenyl succinic acid anhydride in the present invention, under alkaline condition, carries out starch conversion, is formed and be modified
Tapioca, starch is after aoxidizing, molecular chain rupture, and the quantity of hydroxyl reduces, and carboxyl and carbonyl content improve, while introducing carboxylic
After base group, three-dimensional effect hinders the association again of hydrogen bond, and strand is relatively free, under the hydrophilic interaction of carboxyl, water
Molecule largely enters inside starch granules, so that oxidized starch paste be made to keep collosol state for a long time, gel strength is reduced, thus
The degree of polymerization for reducing starch increases the water solubility, cohesive force and stability of starch, a small amount of nano-silica powder is added
Body facilitates the tensile strength and waterproof performance of anti-oil film, and the polymerization that plasticizer glycerol stream avoids nano silica is added,
Gel network structure can be formed in starch film to improve starch-base biodegradation, soybean protein isolate is added, in low humidity conditions
Under, the oxygen permeability of soybean separation protein tunica albuginea is low, while the anti-oil film to be formed is compounded with sodium alginate polysaccharide, increases the glutinous of anti-oil reservoir
Degree makes it uniformly be adhered to brown paper surface, and the carboxyl of the amino and oleic acid molecular that introduce in the oil-proofing agent of formation has occurred quiet
It is electrically coupled, oleic acid molecular is adsorbed on oil-proofing agent molecular surface, prevents the infiltration of grease to a certain extent, enhances the anti-of paper
Oily effect；
(3) present invention is using Hydrolyzed Collagen as raw material, and styrene and butyl acrylate are modified monomer, to Hydrolyzed Collagen
Graft modification is carried out, sizing activating agent is formed, is filled after sizing by penetrating into paper fiber hole, formed and caused in paper surface
Close film improves the mechanical property and water repelling property of paper, is added into greaseproof, on the one hand fixed antibacterial activity thing
Confrontation greaseproof carries out antibacterial action, carries out hydrophobic treatment to paper surface, then oil-proofing agent is applied to the upper of sizing activating agent
Layer forms the grease proofing greaseproof in top layer surface layer, if oleic acid is penetrated into through first layer oil-proofing agent, the sizing activating agent of the second layer
Also the blocking that can be carried out a part of grease prevents from penetrating into brown paper base paper, forms dual anti-oil reservoir, improve oil preventing performance.
