Natural macromolecular material is the same, after this kind of protein material film forming, there are plastic senses it is strong, water-resistance and rotproofness are poor the problems such as.Silicon
Siloxane modified gelatin can improve the water-resistance and flexibility [201310012009.X] of gelatin film to a certain extent, but silicon
Disorder distribution of the oxygen alkane component in film directly affects membrane structure, film properties and film application.
Parents' film can make silicone components be distributed in the one side of film, and another side is gelatin, to make the property of membrane material
Two kinds of properties are also presented in matter and function.The present invention passes through Macromolecular self-assembly mistake for using the interaction between each macromolecular
Journey prepares novel gelatin parents film.
Summary of the invention
The purpose of the present invention is overcoming above-mentioned deficiency, the preparation of monocycle oxygen terminated polysiloxane modified gelatin parents' film is provided
Method, invention preparation have the characteristics that strong gelatin leather finishing agent hydrophobic, ductility is good, thermal stability is low, film is soft.
The technical scheme adopted by the invention is as follows:
A kind of preparation method of monocycle oxygen terminated polysiloxane modified gelatin parents' film, comprises the following steps that
(1) Gelatin Yu Shuizhong being configured to aqueous solution, adjusts its temperature at 40~60 DEG C, regulation system pH is 8~
11, mass concentration is 3~8%, and solution is divided into 4 equal portions, and sodium alkyl sulfate is all added into every portion, stirs 4~8h, wherein
The long alkyl chains of sodium alkyl sulfate are 10,12,14 or 16, and dosage is the 1~20% of gelatin quality；
(2) solution for obtaining step (1) takes out a, and the list that point 1~8 batch of addition molecular weight is 500 is epoxy-capped poly-
Siloxanes, the dosage of monocycle oxygen terminated polysiloxane are 0.04~3.0 times of primary amine groups mole in gelatin molecule, in 40~
60 DEG C of 24~30h of reaction, obtain solution A, and wherein concentration of polymer solution is 1 ~ 30%；
(3) solution for obtaining step (1) takes out a, and the epoxy-capped poly- silicon oxygen of list that molecular weight is 1000 is added portionwise
Alkane, the dosage of monocycle oxygen terminated polysiloxane is 0.04~3.0 times of primary amine groups mole in gelatin molecule, in 40~60 DEG C
24~30h is reacted, solution A is obtained, wherein concentration of polymer solution is 1 ~ 30%；
(4) solution for obtaining step (1) takes out a, and the epoxy-capped poly- silicon oxygen of list that molecular weight is 2000 is added portionwise
Alkane, the dosage of monocycle oxygen terminated polysiloxane is 0.04~3.0 times of primary amine groups mole in gelatin molecule, in 40~60 DEG C
24~30h is reacted, solution A is obtained, wherein concentration of polymer solution is 1 ~ 30%；
(5) solution obtained step (1) takes out a, in 40~70 DEG C of persistently stirrings 12~for 24 hours, obtains solution D,
Middle solution concentration is 1~10%；
(6) by solution A, solution B, solution C and solution D with mass ratio be (1~5): (1~5): (1~5): 1 ratio mix
Afterwards, it obtains containing the polysiloxane-modified gelatin mixed aqueous solution of different weight average molecular weight；
(7) it weighs 5~10g and contains the different polysiloxane-modified gelatin mixed aqueous solutions of weight average molecular weight, be placed in polytetrafluoro
In the mold of ethylene, it is added dehydrated alcohol in a mold, the volume ratio of ethyl alcohol and mixed liquor is 1:(1~8), after mixing,
It is dried in 25~70 DEG C of room temperature baking oven, obtains the modified gelatin film with different contact angles, can be obtained under part of ratio
Parents' film hydrophobic while hydrophilic is obtained, the film ductility is good.
The present invention has following remarkable advantage using the monocycle oxygen terminated polysiloxane modified gelatin of different molecular weight: first
First, the longer monocycle oxygen terminated polysiloxane modified gelatin of molecule segment can form microphase-separated with gelatin molecule, promote material
Embody excellent, special performance.Firstly, monocycle oxygen terminated polysiloxane is incompatible with gelatin, the two is led in film forming procedure
It crosses intermolecular interaction and forms micro phase separation structure, material is promoted to embody excellent, special performance.Secondly, siloxanes group
Change of gradient is presented in point content in the longitudinal direction, makes the two sides of film that heterogeneity be presented, and is on one side gelatin enrichment, can be tight with hide
Close combination；Another side is siloxanes enrichment, and siloxanes is one kind using duplicate Si-O key as main chain, has been directly connected on silicon atom
The polymer of machine group；This special construction of organosilicon and composition, having it, low-temperature flexibility is good, surface tension is low, biological
The features such as compatibility is good, resistance to combustion, good weatherability, water-tolerant, thermostabilization are good and good permeability.Third, silicone components are in film
In be orderly distributed, so that film is had the characteristics that softness, meet suitcase leather, clothing leather or car decoration leather high demand.In exploration
Can superior, cheap hybrid protein finishing agent while, prepare novel gelatin membrane material, obtain the waste of leather industry
To high level conversion.
Monocycle oxygen terminated polysiloxane modified gelatin parents' film of different molecular weight of the present invention can be used as suitcase leather,
The finishing agent of clothing leather or car decoration leather.
