Embodiment 1

[0019] Preparation of nanocomposite modifier: (1) Add 37.5 mL of isopropanol to 1000 mL of deionized water while stirring, then slowly add 37.5 mL of tetraisopropyl titanate dropwise, stir for 1 hour after the addition, and add a little over Oxidize the hydrogen solution until the solution becomes clear. Then transfer it to a constant temperature oil tank, and return to the oil bath for 48 hours to prepare the titanium dioxide sol. After the sol is prepared, add 15g nano-SiO 2 Mixed with 25g nano tourmaline powder to prepare modified TiO 2 Sol. (2) Weigh 100g of carbon nanotube powder and place it in a beaker, disperse it in mixed acid, oscillate ultrasonically for 2 hours, then wash it with deionized water until neutral, filter it through a microporous membrane, put it into a vacuum drying oven, After drying at 110°C for 24 hours, take it out for use. (3) Using carbon nanotubes as a carrier to modify TiO 2 sol for loading, carbon nanotubes and modified TiO 2 The sol was...

Abstract

The invention discloses a nano composite stone material protection agent. A carbon nanotube-supported TiO2 / tourmaline nano-composite modifier is added, wherein the TiO2 particles can reduce the scattering intensity of long wave ultraviolet ray and absorb short wave ultraviolet ray; nano SiO2 particles can absorb and reflect the ultraviolet ray, wavelength being less than 400 nm, and infrared ray,wavelength being larger than 800 nm, both absorption rate and reflection rate reaching more than 70%, so that anti-aging effect of the protection agent is greatly enhanced; meanwhile, the nano-particles have photocatytic function, so that organics can be decomposed at high efficiency. The protection agent is higher than hypochlorous acid in sterilization effect and is significantly enhanced in anti-bacterial corrosion property and improved in self-cleaning performance and adhesion force. Meanwhile, the hardness, anti-scrubbing effect and anti-wearing effect of a coating layer are enhanced by means of the carbon nanotubes and nano SiO2.

Description

Technical field: [0001] The invention relates to a stone protective agent, in particular to a nanocomposite stone protective agent and a preparation method thereof Background technique: [0002] In interior decoration, the application of stone occupies a relatively large proportion. For example, fluorocarbon stone protective agent is widely used in the coating protection of indoor stone countertops and stone wash basins. It is one of the coatings with important applications for indoor high-grade stone protection. Stone waterproof coating is a kind of stone protection technology, which has a wide range of applications in the modern stone industry. The waterproof coating makes the synthetic resin evenly distributed on the surface of the stone or slowly penetrates into the stone to form a protective film, so that the stone has waterproof, anti-fouling, oil-proof, acid and alkali resistance, weathering resistance, aging resistance, freeze-thaw resistance, Anti-biological erosio...
