Water-soluble photocatalytic titanium dioxide sol spray and preparation method thereof

Abstract

The invention relates to the technical field of environmental protection, and discloses a water-soluble photocatalytic titanium dioxide sol spray and a preparation method thereof. The water-soluble photocatalytic titanium dioxide sol spray is prepared from the following raw materials in parts by weight: 3-5 parts of titanium tetrachloride, 50-70 parts of epoxy resin, 10-30 parts of absolute ethylalcohol, 4-6 parts of sodium hydroxide solution, and 8-10 parts of hydrogen peroxide. A nano-titanium dioxide sol spray is used as a photocatalyst and supported on the leaf surface of a plant, providing a large surface area, so that the photocatalyst can be supported effectively and the effect of the photocatalyst can be maintained for a long time; in addition, as the leaf stomates of the plant can absorb automobile exhaust gases, the automobile exhaust gas pollution can be reduced more efficiently by virtue of the coupling of absorption by the leaf stomates and photocatalytic degradation. Thetechnical product is a water-soluble photocatalytic titanium dioxide sol and thus can be used in combination with a multifunctional landscaping pesticide-spraying sprinkler of the transport department, and the catalyst spraying cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water-soluble photocatalytic titanium dioxide sol spray and a preparation method thereof. Background technique [0002] The control and treatment of motor vehicle exhaust has become an important topic in the world. Developed countries have made important progress due to the relatively advanced overall technology of motor vehicles and the control technology of motor vehicle exhaust. Now they are moving towards ultra-low pollution emissions and zero pollution emissions. my country It started late in this area, and many control technologies are in the stage of exploration and trial, but they are striving to be in line with international standards. [0003] There are two types of motor vehicle exhaust purification methods: organic internal purification and external purification. Internal purification is to improve the structure and combustion conditions of internal ...

Problems solved by technology

[0004] Nano-titanium dioxide, also known as transparent ultra-fine titanium dioxide, is an important topic in the field of material science research. Although the current research on nano-photocatalytic ecological roads has achieved preliminary results, and its application in physical engineering has also achieved good results, however, in practical applications The process is affected by a variety of objective factors, such as the adverse effects of nano-photocatalytic materials on the pavement, such as whether the nitrate and sulfate adsorbed in the pavement will cause erosion of pavement materials, etc., such as small application range, single type of degraded pollutants, Active ingredients have short lifespan, etc. Therefore, how to control motor vehicle exhaust in a large area and how to solve high-pollution and large-area road motor vehicle exhaust pollution are still a difficult problem. For this reason, we propose a water-soluble photocatalytic titanium dioxide sol spray and its Preparation
