Problems solved by technology

Nano-silver particles are added to the acrylic plate, and the nano-silver inside the plate cannot touch bacteria. Only the nano-silver on the surface of the plate can touch bacteria, so that the sterilization efficiency of the entire plate is low.

Embodiment 1

[0037] Add 7.5kg of methyl methacrylate monomer into the polymerization reactor, add 1.5g of azobisisobutyronitrile as an initiator, add an appropriate amount of release agent, stir evenly, heat to boiling, the material viscosity reaches about 60s, stop Heat and cool with cooling water, stir and cool to 30°C to prepare a slurry. Take 2.5kg of methyl methacrylate monomer, add 250g of modified nano titanium dioxide and 300g of 731A into the methyl methacrylate monomer, and after ultrasonic dispersion, pour it into the prepolymer, transfer it to a stirring tank, and add 1kg of o-phthalic acid Dibutyl diformate, an appropriate amount of low-temperature initiator and mold release agent, stir evenly, vacuumize and remove air, pour into a silicon glass mold, and discharge air bubbles. Pour the measured material into the silicon glass mold, discharge the air bubbles, and clamp the mold with spring clips. Place the mold filled with material in a water bath, maintain the temperature of...

Abstract

The invention relates to an antibacterial organic glass plate which comprises the following raw materials in percentage: 75-90% of a methyl methacrylate monomer, 0.5-2% of an initiator, 0.5-1% of a release agent, 5-20% of nano titanium dioxide, 0.5-10% of ammonium phosphomolybdate and 1-3% of a surfactant. The antibacterial organic glass plate has the beneficial effects that the antibacterial property of the acrylic plate can be greatly improved by adding the modified nano titanium dioxide in the batching process, the acrylic plate with excellent antibacterial property is obtained, organic matters in bacteria react under the illumination condition, and the titanium dioxide is used as a catalyst to be oxidized to generate CO2 and H2O so as to kill the bacteria; meanwhile, OH and H2O attached to the surface of titanium dioxide are oxidized into. OH. OH which has very strong oxidizing capacity, unsaturated bonds of organic matters are attacked or H atoms are extracted to generate new freeradicals, a chain reaction is excited, and finally bacteria are decomposed. The acrylic plate prepared by adding titanium dioxide is high in sterilization efficiency, free of waste, safe, environmentally friendly and suitable for large-scale production.

Description

technical field [0001] The invention relates to an antibacterial organic glass plate and a preparation method thereof, belonging to the technical field of organic glass processing. Background technique [0002] Plexiglass is also called acrylic, and its chemical name is polymethyl methacrylate. It is a kind of polymer material developed earlier. It has the advantages of smooth surface, high hardness, high temperature resistance, uniform dyeing, and easy molding. Antibacterial acrylic sheet has a broad market prospect. It is widely used in medical, construction and bathroom industries, and has broad application prospects. Under the premise of not changing the physical properties of the acrylic sheet, making the acrylic sheet have antibacterial properties can broaden the application range of the acrylic sheet and increase the added value of the acrylic sheet production. [0003] For example, the invention patent with application number 201510017754.2 introduces a method of us...
