Problems solved by technology
Organic antibacterial materials such as chlorhexidine acetate have been successfully added to inorganic layered carrier materials such as hydrotalcite and montmorillonite, but the temperature resistance of these composite antibacterial materials is less than 200 ° C. In some processes that need to withstand high temperatures (such as plastics, resins, etc.), it is difficult to reach the lower temperature limit required by the process
That is to say, the application of the material is limited

Embodiment 1
[0029] The present embodiment utilizes the preparation method of the present invention to prepare the imidazolium ionic liquid intercalation α-ammonium phosphate titanium composite antibacterial material, which has the following general formula: Ti[(C n MIM)PO 4 ] 2 ; where (C n MIM) represents 1-alkyl-3-methylimidazolium cation (n is a natural number from 1 to 20), and the specific preparation steps of the material are as follows:
[0030] 1) According to bromide 1-tetradecyl-3 methylimidazolium ionic liquid ([C 14 MIM] Br) and the mol ratio of α-titanium ammonium phosphate are weighed in the ratio of 1: 10;
[0031] The ionic liquid described in this embodiment is: imidazolium ionic liquid. The conventional synthetic technique of imidazolium ionic liquid obtains, is that this professional and technical personnel can implement, for example by alkyl imidazolium cation and F - , Cl - 、Br - , I - Anion, combined according to the conventional process to obtain the halogen...

Heat-resistant composite antibacterial functional material and the preparation method thereof are provided. Imidazole ionic liquid and Ti ammonium a-phosphate undergo intercalation assembling to prepare the antibacterial materials. The general formula of the antibacterial material is shown as follows: Ti(A)b(PO4)2, wherein A represents the cation of imidazole ionic liquid, b represents 1 or 2. The antibacterial material can keep its structure and antibacterial function unchanged under the temperature of 250? or above, and have more than 90% antibacterial efficiency for sensitive bacteria.
Description
technical field [0001] The invention relates to an antibacterial functional material and a preparation method thereof, in particular to a novel heat-resistant composite antibacterial functional material synthesized by using ionic liquid and an inorganic carrier as raw materials and a preparation method thereof. Background technique [0002] Heat-resistant composite antibacterial functional materials are currently a hot spot in the research of antibacterial materials. This material has both the high temperature resistance characteristics of inorganic materials and organic antibacterial materials. The antibacterial effect is good and the sterilization speed is fast. advantage. Organic antibacterial materials such as chlorhexidine acetate have been successfully added to inorganic layered carrier materials such as hydrotalcite and montmorillonite, but the temperature resistance of these composite antibacterial materials is less than 200 ° C. In some processes that need to withst...
