Embodiment 1

[0012] Add 100 grams of urushiol in a 500 milliliter three-necked flask, 3.0 grams of organic montmorillonite (BP-183) soaked in an appropriate amount of xylene solution for 48 hours, 6.2 grams of hexamethylenetetramine, 150 grams of xylene, and ultrasonically After shaking for 30 minutes, install a thermometer, agitator, water separator and condenser; raise the temperature to 80-90°C for 1 hour, then raise the temperature to 138-140°C and heat to reflux for 2 hours, lower the temperature to 110-118°C, add 55.5 grams of n-butanol and 1.6 grams of phosphoric acid were heated and stirred at 110-118° C. for 1 hour to obtain urushiol-formaldehyde condensation polymer / montmorillonite nanocomposite coating.

Embodiment 2

[0013] Embodiment 2: Add 100 kilograms of urushiol, 6.2 kilograms of hexamethylenetetramine, 150 kilograms of xylenes, 3.0 kilograms of organic compounds that have been immersed in an appropriate amount of xylene solution for 48 hours and ultrasonically vibrated for 30 minutes in a 500-liter reactor. For montmorillonite (BP-183), heat up to 80-90°C for 1 hour, then heat up to 138-140°C and heat to reflux for 1.5 hours, lower the temperature to 110-118°C, add 55.5 kg of n-butanol and 1.6 kg of phosphoric acid, continue Heating and stirring at 110-118° C. for 1 hour, and cooling to prepare the urushiol-formaldehyde polycondensate / montmorillonite nanocomposite coating.

Abstract

The present invention discloses the preparation process of nano urushiol formaldehyde condensation polymer / montmorillonite composite paint. The nano composite paint is prepared with urushiol, hexamethine tetramine and organic montmorillonite as material, and through intercalation, condensation and butylation. The nano composite paint has physical and mechanical performance similar to that of urushiol formaldehyde condensation lacquer but greatly raised uvioresistant capacity.

Description

technical field [0001] The invention relates to a nanocomposite coating and a preparation method thereof, in particular to a method for preparing urushiol-formaldehyde polycondensate / montmorillonite nanocomposite coating with urushiol as a main raw material. Background technique [0002] As early as 1958, Zeng Weicong and others successfully prepared urushiol formal varnish, which is one of the earliest modified products of urushiol. Compared with raw lacquer, urushiol formal varnish is lighter in color, does not have the toxicity of raw lacquer that can cause skin allergies, can dry by itself, and can be applied by various methods such as spraying, rolling, dipping, and brushing. Its paint film not only has good physical and mechanical properties, but also has good chemical corrosion resistance, especially good pesticide corrosion resistance. It has been applied in pesticide sprayers, plant protection machinery, appliances and chemical corrosion protection. However, urushi...
