Problems solved by technology

At present, the tolerance temperature of existing composite antibacterial materials is basically 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

Abstract

The invention discloses a heat-resistant composite antibacterial functional material, which is composed of hollow mesoporous silica and nano silver particles and alpha-ammonia titanium phosphate filled in hollow mesopores of the hollow mesoporous silica, wherein the mass ratio of the nano silver particles to the alpha-ammonia titanium phosphate is 2:5 to 3:7; thealpha-ammonia titanium phosphate isobtained through conventional synthesis by mixing alpha-titanium hydrogen phosphate and ammonia water in a molar ratio of 1:5 to 4:5, in which the H<+> on the -OH group of the titanium hydrogen phosphate layer is replaced by NH<4+>. In the invention, the hollow mesoporous silica is used as a solid carrier, so that the nano silver particles can be dispersed and embedded in the hollow mesopores toachieve the slow release of the active ingredient; and then the alpha-ammonia titanium phosphate wraps the outside of the hollow mesoporous silica loaded with the nano silver particles loaded, therebygreatly improves the heat resistance of the material.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a preparation method of a heat-resistant composite antibacterial functional material. 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. At present, the tolerance temperature of existing composite antibacterial materials is basically 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 this material is limited. Contents of the invention [0003] In order to solve the above problems, the prese...
