Embodiment 1

[0024] Embodiment 1: use pig hair as raw material to make non-waterproof protein film

[0025] Choose 1000 kilograms of variegated pig hair raw materials to manufacture protein film, and its technological process is as follows:

[0026] (1) Remove the large debris mixed in the pig hair, and then use clean water to clean the blood, feces, sand and other sundries stuck on the pig hair in an industrial washing machine and then dry it;

[0027] (2) Put pig hairs into a stainless steel tank, add 1% NaOH aqueous solution submerged in pig hairs, soak at room temperature for 96 hours, make the pig hairs soft, then dry them with a press and recover the lye;

[0028] (3) sending the softened pig hair into a grinding mill to be crushed into 10 mesh coarse grains;

[0029] (4) Put the crushed pig hair into a stainless steel tank, add 6% H that has not passed the pig hair 2 o 2 After soaking the solution at 70°C until it is colorless, send it to a filter press to filter and recover the ...

Embodiment 2

[0033] Embodiment 2: use chicken feather as raw material to make non-waterproof protein film

[0034] Choose 1000 kilograms of white chicken feather raw materials to manufacture protein film, and its technological process is as follows:

[0035] (1) Remove the large pieces of sundries mixed in the chicken feathers, and then use clean water to clean the blood, feces, sand and other sundries on the chicken feathers in an industrial washing machine, and then dry them;

[0036] (2) Put the chicken feathers into a stainless steel tank, add 0.4% NaOH aqueous solution that has not passed the chicken feathers, soak for 72 hours at room temperature, make the chicken feathers soft and then dry them with a press and recover the lye;

[0037] (3) Feather after softening is sent into the grinding mill and crushed into 10 mesh coarse grains;

[0038] (4) Put the crushed chicken feathers into a stainless steel pot, add 0.1‰ alkaline protease aqueous solution that has not crossed the chicken...

Embodiment 3

[0041] Embodiment 3: make waterproof protein film with ox horn as raw material

[0042] Choose 100 kilograms of variegated cattle and sheep horn raw materials to manufacture protein film, and its technological process is as follows:

[0043] (1) After the ox horns are cut into slices with a slicer, the blood, feces, sand and other debris adhering to the ox horns are cleaned with clear water in an industrial washing machine and then dried;

[0044] (2) Put the horns of cattle and sheep into a stainless steel tank, add 0.8% KOH aqueous solution that has not passed the horns of cattle and sheep, soak for 72 hours at room temperature, make the horns of cattle and sheep soft, squeeze them dry with a press and recover the lye;

[0045] (3) sending the softened cattle and sheep horns into a grinder and crushing into 10 mesh coarse grains;

[0046] (4) Put the crushed cattle and sheep horns into a stainless steel tank, add 4% H that has not passed the cattle and sheep horns 2 o 2 A...

Abstract

Disclosed are a protein membrance for fur of animals such as chicken, duck, goose and pig, ox and sheep, and hard protein of horn of ox, goat, of hoof shell of pig, ox and sheep, made by softening, crushing down and hydrolysis, and its preparing method. The protein membrance can be made into that has resistance to water or not, replacing for plastic mulching film, plastic film or packaging material of whole degradation without pollution. The intermediate-albumin gluegenerated in the preparing course can be used as stickerwithout pollution for chemical and dye printing industries. The invention has abundant raw material, simple technique, low cost, comprehensive usage, no pollution to the environment and no need for special equipment, with wide application range and value; it will bring about remarkable social and economic benefits.

Description

technical field [0001] The present invention relates to a kind of protein film and preparation method thereof that utilize the horny protein of livestock and poultry. Background technique [0002] At present, a large amount of livestock and poultry hairs such as poultry, chickens, ducks and goose feathers, livestock waste pig and cattle wool, livestock horns such as cattle and sheep horns, hoof shells of pigs, cattle and sheep, etc., these raw materials are collectively referred to as livestock and poultry hair horn protein in the present invention. Most of these livestock and poultry keratin proteins are discarded as garbage, seriously polluting the environment, and have not been rationally developed and utilized. Contents of the invention [0003] The purpose of the present invention is to provide a protein film that can replace agricultural plastic film or packaging film by using keratin of livestock and poultry hair a...
