Problems solved by technology

[0002] With the improvement of the quality of human life, the research on antibacterial materials has developed rapidly, but the antibacterial performance of the antibacterial materials currently used is not ideal, and the general antibacterial rate can reach 80%. The requirements are getting higher and higher, so it is necessary to develop a medical material with excellent comprehensive performance, stronger antibacterial performance, and harmless to living organisms or the environment.

Embodiment 1

[0017] A kind of preparation method of novel antibacterial material, this method comprises the following steps:

[0018] Step 1, 65 parts of polyethylene, 13 parts of Cu-MOF-Al 2 o 3 Nanomaterials, 3 parts of ethyl formate and 5 parts of polylactic acid were added to the reactor, and 1 part of sodium carbonate, 5 parts of lauryl betaine, 1 part of sodium tripolyphosphate and 0.8 parts of sodium xylene sulfonate were dissolved in 30 parts water, then add it into the reaction kettle, stir and mix evenly under the condition of 50°C, the stirring speed of stirring and mixing is 150 rpm, and the mixing time is 30 minutes, then raise the temperature to 80°C under the vacuum degree of 0.01MPa, stir After 20 minutes, the temperature was raised to 130° C., and the reaction was stirred for 30 minutes to obtain the initial product;

[0019] Step 2. Add 1.5 parts of antioxidant BHT and 1.3 parts of co-antioxidant DLTP to the primary product obtained in step 1, stir and mix evenly at a t...

Embodiment 2

[0029] Step 1, 50 parts of polyethylene, 16 parts of Cu-MOF-Al 2 o 3 Nanomaterials, 4 parts of ethyl formate and 5 parts of polylactic acid were added to the reaction kettle, and 1 part of sodium carbonate, 5 parts of lauryl betaine, 1 part of sodium tripolyphosphate and 0.8 parts of sodium xylene sulfonate were dissolved in 30 parts water, then add it into the reaction kettle, stir and mix evenly under the condition of 50°C, the stirring speed of stirring and mixing is 150 rpm, and the mixing time is 30 minutes, then raise the temperature to 80°C under the vacuum degree of 0.01MPa, stir After 20 minutes, the temperature was raised to 130° C., and the reaction was stirred for 30 minutes to obtain the initial product;

[0030] All the other preparations are the same as in Example 1.

Embodiment 3

[0032] Step 1, step 1, 45 parts of polyethylene, 23 parts of Cu-MOF-Al 2 o 3 Nanomaterials, 6 parts of ethyl formate and 5 parts of polylactic acid were added to the reactor, and 1 part of sodium carbonate, 5 parts of lauryl betaine, 1 part of sodium tripolyphosphate and 0.8 parts of sodium xylene sulfonate were dissolved in 30 parts water, then add it into the reaction kettle, stir and mix evenly under the condition of 50°C, the stirring speed of stirring and mixing is 150 rpm, and the mixing time is 30 minutes, then raise the temperature to 80°C under the vacuum degree of 0.01MPa, stir After 20 minutes, the temperature was raised to 130° C., and the reaction was stirred for 30 minutes to obtain the initial product;

[0033] All the other preparations are the same as in Example 1.

Abstract

The invention discloses a method for preparing a novel antibacterial material. According to the method, polyethylene, a Cu-MOF-Al2O3 nano material, ethyl formate, polylactic acid, sodium carbonate, laurylanido propyl betaine, sodium tripolyphosphate and sodium xylene sulfonate are adopted as main raw materials, a double-layer structure platform is established through MOF organic ligands, polyethylene is hid under a biological pollution prevention 'clean' surface, under a dry-state condition, an outermost molecule brush surface is subjected to water loss collapse, bacteria propagated through gases and liquid droplets are killed by antibacterial compositions inside in a contact sterilization mode, under a water phase condition, an amphoteric polymer of an outer layer forms a hydration shell,then bacteria in solutions are prevented from adhesion, and the antibacterial properties of materials are improved. The method disclosed by the invention is green and environmental-friendly and relatively small in environment influence, and a material prepared by using the method has a relatively good antibacterial effect on escherichia coli and staphylococcus.
