Abstract

The invention discloses a preparation method of an anatase-type nanomaterial and self-cleaning solar glass made from the nanomaterial, and provides a method for producing a nanomaterial which is used as a self-cleaning coating on glass in the natural environments, and self-cleaning solar glass made from the nanomaterial. The preparation method comprises the following steps: (1) introducing nitrogen gas with high purity up to 99.99% into a Ti(OR)4 gasifier, a water gasifier, a mixing section of a reactor and a hydrolysis reaction section of the reactor respectively; mixing Ti(OR)4 vapor-carrying nitrogen gas with cold nitrogen gas in the mixing section to form Ti(OR)4 aerosol particles; transferring the Ti(OR)4 aerosol particles to the hydrolysis reaction section of the reactor, and mixing and carrying out hydrolysis reaction on the Ti(OR)4 aerosol particles and water vapor in the hydrolysis reaction section of the reactor, to produce TiO2 ultrafine particles. The self-cleaning solar glass made from the nanomaterial is produced by spray-coating the nanomaterial on the outer surface of glass at normal temperature and curing at normal temperature. The method is simple and low in cost, and the production of the self-cleaning solar glass from the nanomaterial is convenient.

Description

technical field

[0001] The invention relates to an anatase nanometer TiO 2 The preparation method and the product application of using the nanomaterial obtained by the method to make self-cleaning solar glass, the self-cleaning solar glass involved can be the glass used in solar glass vacuum heat collection tubes, solar photovoltaic glass, solar curtain walls, etc. technical background

[0002] With the limitations of conventional energy sources such as petrochemicals and the increasingly serious problem of environmental pollution, countries around the world are also accelerating investment in new energy sources. Outline and gist of the "Twelfth Five-Year Plan" "Emerging Energy Industry Development Plan" In the next ten years, China's energy development will mainly advance towards two goals. One is that by 2020, the proportion of non-fossil energy in total primary energy consumption will reach about 15%. ; Second, by 2020, China's carbon dioxide emissions per unit of GDP wi...
