Embodiment 1

[0029] A kind of preparation method of antibacterial fiber sponge material of the present invention, preparation process is as follows figure 1 shown, including the following steps:

[0030] (1) Get the mulberry branch and wash away the sediment with tap water, dry it at 78°C for 24 hours, grind the mulberry branch into mulberry branch powder, and pass the mulberry branch powder through a 10-mesh sieve to obtain a mulberry branch powder with a particle size of about 2mm;

[0031] (2) Weigh 0.334g of mulberry branch powder, add 5g of ([EMIM][Ac]) and mix uniformly, and heat the uniformly mixed solution to 100°C in a collector-type constant temperature heating magnetic stirrer until dissolved, Heating for 40min;

[0032] (3) Inject the mixture into the pre-prepared mold, weigh 20g of anhydrous sodium sulfate, add it into it and stir continuously until the mixture is uniform, and mold it at 90°C for 1 hour to obtain a semi-finished product;

[0033] (4) Wash the semi-finished p...

Embodiment 2

[0036] (1) Get the mulberry branch and wash away the sediment with tap water, dry it at 78°C for 24 hours, grind the mulberry branch into mulberry branch powder, and pass the mulberry branch powder through a 10-mesh sieve to obtain a mulberry branch powder with a particle size of about 2mm;

[0037] (2) Weigh 0.2g of mulberry branch powder, add 4g of ([EMIM][DEP]) and mix evenly, and heat the uniformly mixed solution to 100°C in a collector type constant temperature heating magnetic stirrer until it dissolves, Heating for 1h;

[0038] (3) Inject the mixture into the pre-prepared mold, weigh 12.6g of anhydrous sodium sulfate, add it into it and stir continuously until the mixture is uniform, and mold it at 90°C for 1 hour to obtain a semi-finished product;

[0039] (4) Wash the semi-finished product with distilled water at 50°C to remove the pore-forming agent and excess solvent, then take 10ml of the prepared cellulase solution with a concentration of 0.0025g / ml and add it to ...

Embodiment 3

[0042] (1) Get the mulberry branch and wash away the sediment with tap water, dry it at 78°C for 24 hours, grind the mulberry branch into mulberry branch powder, and pass the mulberry branch powder through a 10-mesh sieve to obtain a mulberry branch powder with a particle size of about 2mm;

[0043](2) Weigh 0.3g of mulberry powder, add 6g of [AMIM][Cl] and mix evenly, heat the mixed solution to 80°C in a collector-type constant temperature heating magnetic stirrer until dissolved, and heat for 30min ;

[0044] (3) Inject the mixture into the pre-prepared mold, weigh 25.2g of anhydrous sodium chloride, add it and stir continuously until the mixture is uniform, and mold at 90°C for 1.5h to form a semi-finished product;

[0045] (4) Wash the semi-finished product with ethanol at 50°C to remove the pore-forming agent and excess solvent, then take 10ml of the cellulase solution with a concentration of 0.0025g / ml and add it to the mold, and add buffer to adjust the pH to 6 , react...

Abstract

The invention discloses a preparation method of an antibacterial fiber sponge material, which comprises the following steps: (1) washing mulberry branches, drying and crushing to a certain particle size to obtain mulberry branch powder; (2) taking a certain amount of mulberry branch powder and a certain After a certain amount of configured ionic liquid is mixed in a three-necked flask, heat treatment in a heat-collecting constant temperature heating magnetic stirrer; (3) the sample obtained in step (2) is placed in a mold, an appropriate amount of pore-forming agent is added, and stirred evenly, Molding; (4) washing to remove the pore-forming agent and excess solvent, adding the prepared cellulase solution into the mold for reaction; (5) freezing the molded sample and freeze-drying at low temperature to obtain the finished product of the fiber sponge. The invention adopts the renewable mulberry waste as raw material, the regeneration cycle is rapid, the environmental pollution caused by the mulberry burning is avoided, and the high-value conversion of the mulberry waste is realized at the same time; it has the characteristics of ventilation, water retention and moisturizing, and has no allergens , no immune response, natural antibacterial effect and other advantages.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial fiber sponge material, which belongs to the field of biochemical industry. Background technique [0002] Artificial sponge has existed for decades as a daily necessities. The sponge products sold in the market are mainly made of polyurethane and polystyrene. Not only the production process will pollute the environment, but also the discarded sponge is difficult to degrade. The raw material of artificial sponge mainly comes from petroleum, and along with the continuous reduction of petroleum resources, the source of raw material will also be a serious problem. In recent years, people have a better understanding of environmental protection, and there must be a new environmentally friendly sponge to replace it. Therefore, people are committed to the research and development of environmentally friendly and natural bio-sponges for cosmetics, high-tech adsorbents and other products with high...
