Embodiment 1
[0012] In the reactor with agitator, add the following raw materials by weight percentage: 0.10% trimethylolpropane triacrylate, 0.05% nano titanium phosphate, 15% novolac epoxy resin, particle size is 10 oily nano Titanium dioxide 0.8%, nano-anion powder 1.0%, YL-109 defoamer 0.001%, silane coupling agent 0.003%, dibutyltin dilaurate 0.003%, polyacrylate 0.02%, the balance is water; after adding the mixture, fully stir Mix evenly to form a mixture, stir at room temperature at a speed of 1500 rpm for 5 minutes, and allow it to react for 2 hours to obtain a transparent ultraviolet bactericidal coating.
[0013] Under the irradiation of light, the present invention will produce a photocatalytic reaction similar to photosynthesis, produce free hydroxyl groups and active oxygen with strong oxidation ability, have strong photoredox function, and can oxidize and decompose various organic compounds and Some inorganic substances can destroy bacterial cell membranes and solidify virus ...

Abstract
The invention provides a transparent ultraviolet sterilization paint. The paint comprises, by weight, 0.05-0.15% of trimethylolpropane triacrylate, 0.05-0.15% of nanometer titanium phosphate, 10-16% of novolac epoxy resin, 0.5-1.5% of oily nanometer titanium dioxide, 0.5-1.5% of nanometer negative ion powder, 0.001-0.004% of an antifoaming agent, 0.001-0.004% of a silane coupling agent, 0.001-0.004% of dibutyltin dilaurate, 0.01-0.04% of polyacrylate, and the balance water, wherein the antifoaming agent is YL-109; and the granularity of the oily nanometer zinc oxide is 10-35nm. The paint of the invention, which is nontoxic, odorless, safe and environmentally friendly, can generate a photocatalytic reaction like photosynthesis under the light irradiation and generate free hydroxyl radicals and active oxygen with extremely strong oxidation capabilities, so the paint which has a very strong photoredox function can oxidize-decompose various organic compounds and partial inorganic substances, destroy cell membranes of bacteria, cure proteins of viruses, kill the bacteria, decompose organic pollutants, and decompose the organic pollutants into pollution-free water (H2O) and carbon dioxide (CO2), thereby the paint has extremely strong sterilization, deodorizing, mildew resisting, antifouling, self-cleaning, and air purifying functions. The paint can efficiently, rapidly and lastingly purify air.
Description
technical field [0001] The invention belongs to the field of materials, especially the field of new energy materials, and specifically relates to an ultraviolet bactericidal coating. Background technique [0002] It is understood that due to the lack of relevant laws and regulations in the interior decoration industry to regulate the industry, fake and inferior products flood the market, making decoration pollution one of the main killers threatening people's health. Moreover, in recent years, the number of cardiovascular diseases such as hypertension and coronary heart disease among middle-aged and elderly people caused by interior decoration has increased year by year. Harmful substances in decoration materials are the culprit. Harmful substances in decoration materials are mainly radon, formaldehyde, benzene, TVOC, ammonia, etc. Radon exists in natural marble, wood-based panels, paints and various raw materials. Long-term exposure to radon can cause cancer. About 10% of ...
