Problems solved by technology
The assembly and production methods in the prior art are usually to coat the components or components with an adhesive in advance, or attach a layer of pressure-sensitive adhesive to the surface of the silicone rubber material to achieve better adhesion between each other. , but the disadvantage of this method is that the processing procedure is cumbersome, and the requirements for the adhesive are high, and the adhesive usually needs to have good comprehensive properties, such as antibacterial, weather resistance, etc.
However, the polymers used in these fields are exposed to the outside for a long time, and their surfaces are prone to growth and reproduction of various harmful microorganisms. These microorganisms will easily cause biofouling and biocorrosion of materials over time, and even threaten human health

Abstract
The invention belongs to the technical field of rubber materials, and particularly relates to a self-adhesive antibacterial silicone rubber patch and a preparation method thereof, and the self-adhesive antibacterial silicone rubber patch comprises the following components by weight: 100 parts of antibacterial silicone rubber, 20-60 parts of a reinforcing agent, 3-8 parts of a structure control agent, 1-3 parts of a vulcanizing agent, 1-3 parts of a flame retardant, and 1-3 parts of an antioxidant. All the components of the composition have a good synergistic effect; the prepared silicone rubber patch has the advantages of wide spectrum, high antibacterial property, good biocompatibility, low toxicity, good weather resistance, excellent mechanical properties, good self-adhesion and good storage stability; in addition, the preparation method is simple, the raw materials are easy to obtain, the energy is saved, the environment is protected, the reproducibility is good, and the productionefficiency is high.
Description
technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a self-adhesive antibacterial silicone rubber and a preparation method thereof. Background technique [0002] Silicone rubber materials are widely used in the assembly and production of electronic components, equipment components and other supplies. In many cases, it is required to have good adhesion between silicone rubber and components and sub-assemblies to achieve the desired effect. The assembly and production methods in the prior art are usually to coat the components or components with an adhesive in advance, or attach a layer of pressure-sensitive adhesive to the surface of the silicone rubber material to achieve better adhesion between each other. , but the disadvantage of this method is that the processing procedure is cumbersome, and the requirements for the adhesive are high, and the adhesive usually needs to have good comprehensive properties, s...
