Embodiment 1

[0020] Preparation of two-dimensional hexagonal boron nitride nanosheets: first, 33.80 g of lithium tetraborate (Li 2 B 4 o 7 ), 39.00g of sodium azide (NaN 3 ) and 19.20g of 400-mesh metal magnesium powder (Mg) are ball-milled and placed in a 500mL stainless steel high-temperature reaction kettle, sealed and put into a muffle furnace, and heated to 500°C at a rate of 10°C / min. Keep warm for 18 hours, and cool down to room temperature naturally after the reaction is completed. Take out the product in the high-temperature reactor and wash it with absolute ethanol and deionized water for 4 times, then soak it in a hydrochloric acid solution with a volume ratio of 1:1 and stir for 4 hours. During this period, the concentration of hydrochloric acid should be monitored, and the hydrochloric acid solution should be replenished in time. After the reaction was complete, the product was filtered with suction and washed three times with absolute ethanol. Finally, the cleaned product...

Embodiment 2

[0029] Preparation of two-dimensional hexagonal boron nitride nanosheets: first, 33.80 g of lithium tetraborate (Li 2 B 4 o 7 )), 63.50g of sodium azide (NaN 3 ) and 32.86g of 400-mesh metal magnesium powder (Mg) are ball-milled and placed in a 500mL stainless steel high-temperature reaction kettle, sealed and put into a muffle furnace, and heated to 600°C at a rate of 5°C / min. Keep warm for 24 hours, and cool down to room temperature naturally after the reaction is completed. Take out the product in the high-temperature reactor and wash it with absolute ethanol and deionized water for 4 times, then soak it in a hydrochloric acid solution with a volume ratio of 1:1 and stir for 4 hours.

Abstract

The invention discloses nanometer material modified fluorocarbon resin stone material waterproof paint. The paint is prepared from the following ingredients: a resin raw material composed of polyvinylidene fluoride resin and acrylic resin, a hexagonal phase boron nitride two dimension nanosheet, a silane coupling agent, dibutyltin dichloride and solvent oil. By two-dimensional nanometer material modification technology, on the premise of guaranteeing the light transmittance and glossiness of the stone material waterproof paint, the hardness, abrasive resistance and permeation resistance of thestone material waterproof paint are substantially improved, so that the protection lifetime and protection effect of the stone material waterproof paint are remarkably improved.

Description

Technical field: [0001] The invention relates to a stone waterproof coating, in particular to a nano-material modified fluorocarbon resin stone waterproof coating and a preparation method thereof. Background technique: [0002] 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 erosion and other functions, so as to improve the service life and decorative performance of stone. Fluorocarbon resin waterproof coating belongs to a new generation of stone waterproofing agent. Compared with traditional coatings, it has many excellent characteristics, such as extremely low surf...
