1. a kind of production method of bacteria cellulose thermos flask crust, which comprises the following steps:

Wood gluconacetobacter is first activated, then seed liquor is inoculated into culture medium according to the inoculum concentration that volume ratio is 4%, is put into Stationary culture 6d in 30 DEG C of constant incubators.The bacteria cellulose film for then taking out generation is put into immersion treatment in NaOH solution, The distilled water flushing of flowing is used again, until the close neutrality of the pH of flushing liquor.

Bacteria cellulose film obtained above is put into beater, 12000rpm polishes 10 minutes；

Above-mentioned gained paste bacteria cellulose is subjected to sterilization treatment.

Paste bacteria cellulose after sterilizing is poured onto thermos flask crust mold, dry, cooling, air-dried molding.

2. bacteria cellulose thermos flask crust according to claim 1 is it is characterized by: the thickness of bacteria cellulose exists Between 0.25cm-0.6cm.

3. bacteria cellulose thermos flask crust according to claim 2 is it is characterized by: the thermos flask skin thickness is about 0.2mm。

4. bacteria cellulose thermos flask crust according to claim 3 it is characterized by: the thermos flask crust contain pot lid and Bottle body two parts.

5. bacteria cellulose thermos flask crust according to claim 4 it is characterized by: the thermos flask crust pot lid and pot Body two parts can individualism, can intact combination.

Technical field

The present invention relates to a kind of preparation processes based on bacteria cellulose material thermos flask crust, belong to chemical field.

Background technique

Bacteria cellulose refer at different conditions, by acetic acid Pseudomonas, Agrobacterium, rhizobium etc. certain is micro- The general designation of the cellulose of biosynthesis.It has many unique compared with plant cellulose, artificial synthesized bacteria cellulose Property.

1. bacteria cellulose, without the associations product such as lignin, pectin and hemicellulose, has height compared with plant cellulose Crystallinity and the high degree of polymerization；

2. hyperfine reticular structure.Bacteria cellulose fibre is to be combined into 40~60 nanometers by 3~4 nanometers of diameter of fento Thick fibre bundle, and it is intertwined to form flourishing hyperfine network structure；

3. the elasticity modulus of bacteria cellulose is the several times of general plant fiber to ten times or more, and tensile strength is high；

4. bacterial fibers are known as higher biocompatibility, adaptability and good biodegradability；

5. Modulatory character when bacteria cellulose biosynthesis.

Bacteria cellulose thermos flask crust holds tool by pure bacteria cellulose is refined.Mainly for there is glasses The people of demand hold glasses.The shape of thermos flask crust is in elongated ellipsoid shaped, and thermos flask crust shown in reference shape market is The use type that consumer welcomes.The size of thermos flask crust can be varied, can also print text, trade mark and figure as needed Case, so that specific customization appearance is preferably presented.

At present, it is common to use thermos flask crust, shell majority is made of plastics and chemical component, is largely made for a long time With certain adverse effect can be generated to environment, while can also cause a degree of destruction to environment.And bacteria cellulose is warm Pot crust can then avoid problem above.

Summary of the invention

When the technical problems to be solved by the invention, a kind of thermos flask crust manufacture craft is provided, is to mention more specifically For a kind of manufacture craft by bacteria cellulose production thermos flask crust.

In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of system of bacteria cellulose thermos flask crust Make technique, the thermos flask crust manufacture craft is divided into following steps:

Wood gluconacetobacter is first activated, then seed liquor is inoculated into culture medium according to the inoculum concentration that volume ratio is 4%, It is put into stationary culture 6d in 30 DEG C of constant incubators.The bacteria cellulose film for then taking out generation, is put into NaOH solution and impregnates Processing, then with the distilled water flushing of flowing, until the pH of flushing liquor is close to neutral.

Bacteria cellulose film obtained above is put into beater, 12000rpm polishes 10 minutes；

Above-mentioned gained paste bacteria cellulose is subjected to sterilization treatment.

Paste bacteria cellulose after sterilizing is poured onto thermos flask crust mold, dry, cooling, air-dried molding；

It is an advantage of the invention that thermos flask crust manufacture craft of the invention, unique constituent is exactly bacterial fibers Element.Bacteria cellulose is a kind of pure edible bacteria cellulose, also not any to human body and environment even if being used for a long time Damage, without any toxicity and side effects, and production method is simple.
