Antibacterial polymethyl methacrylate and preparation method thereof

Abstract

The invention discloses an antibacterial polymethyl methacrylate and a preparation method thereof. Mesoporous silica can be taken as a carrier, nano silver can be generated on the surface and holes ofthe mesoporous silica in situ, so that mesoporous silica particles carrying the nano silver can be obtained, and the phenomenon of nano silver agglomeration can be effectively solved; uniform dispersing in a polymethyl methacrylate substrate can be achieved, and as the addition of the nano silver particles, the polymethyl methacrylate can have good broad-spectrum antibacterial, powerful bactericidal and lasting antibacterial effects; and a cross-linked network can be formed by connecting modified silica composite particles and polymers through chemical bonds, and therefore, interfacial forcecan be enhanced, and the thermostability of the polymethyl methacrylate can be increased.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antibacterial organic glass and a preparation method thereof. Background technique [0002] Plexiglass usually refers to polymethyl methacrylate, which is the plastic with the best transparency so far. Its light transmittance can be as high as 93%, which is more than 10% higher than ordinary inorganic glass, and The density is very small, compared with traditional silica glass, its mechanical properties and toughness have been greatly improved, and its performance in terms of processing performance is also quite excellent. The preparation of colored organic glass is also much simpler than inorganic glass. Excellent insulation performance is also an important feature of it. Because of its many advantages, it is widely used in construction, culture and education, navigation, aviation and daily life. [0003] Due to its good antibacterial effect, nano silve...

AI Technical Summary

Problems solved by technology

[0003] Due to its good antibacterial effect, nano silver has been applied to the production of products in various fields, such as medicine and medical equipment, antibacterial plastics and rubber products, antibacterial textiles and clothing footwear, antibacterial coatings, ceramics and glass, green antibacterial coatings, etc. Applying nano-silver to plexiglass can endow the plexiglass with an antibacterial effect. However, how to solve the phenomenon of nano-silver agglomeration and uneven distribution in the preparation process has become a research hotspot.
