A kind of self-adhesive antibacterial silicone rubber and preparation method thereof

Abstract

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. The formula composition of the self-adhesive antibacterial silicone rubber patch is by weight: 100 parts of antibacterial silicone rubber, 20 parts of reinforcing agent 60 parts, 3-8 parts of structure control agent, 1-3 parts of vulcanizing agent, 1-3 parts of flame retardant, 1-3 parts of antioxidant. The various components of the present invention have good synergistic effect, good compatibility with silicone rubber, and the prepared silicone rubber patch has broad-spectrum high antibacterial properties, good biocompatibility, low toxicity and good weather resistance, mechanical properties The invention has the advantages of excellent performance, good self-adhesiveness and storage stability, and in addition, the preparation method is simple, the raw materials are easy to obtain, energy saving and environmental protection, good reproducibility and high production efficiency.

Description

Technical field [0001] The present invention belongs to the field of rubber material technology, specifically relates to a self-adhesive antibacterial silicone rubber and a preparation method thereof. Background [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 that the silicone rubber has good adhesion performance between components and components to achieve the desired effect. The assembly and production methods in the prior art are usually coated with a binder in advance on components or components, or a layer of pressure-sensitive adhesive is attached to the surface of the silicone rubber material to achieve a better bond between each other, but the disadvantage of this method is that the processing process is cumbersome, and the requirements for the binder are high, and the binder usually needs to have good comprehensive properties, such as antiba...

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
