Abstract

The invention provides a primer matched paint and a preparation method thereof. The primer matched paint is composed of a photocuring fluorine-containing aircraft skin enamel paint and an ultraviolet-curing polyurethane acrylate primer. The preparation method comprises the following steps: mixing the components, dispersing by sanding, processing by an ultrasonic dispersion technique for 40-120 minutes until the fineness reaches 10 mu m and the observation by an electron microscope shows that the nano TiO2 is uniformly dispersed in the paint solution, storing at 50 DEG C for 28 days, and slightly precipitating the paint. The VOC (volatile organic compound) of the primer matched paint can be lowered to 10% below. The weather resistance, mold resistance, salt spray resistance and damp-heat resistance of the paint are greatly enhanced, thereby ensuring that the formed cured paint film has excellent protective actions.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a primer matching paint and a preparation method thereof. Background technique [0002] The coating system composed of TB06-9 zinc yellow polyurethane primer and TS96-71 fluorine polyurethane enamel developed by our company can meet the skin protection requirements of the third-generation aircraft currently in service, but it is a solvent-based paint with an organic solvent content of 50%. , and the overall coating process has a long cycle, and it takes more than ten hours to dry only by heating and baking, which takes up a lot of machine positions and consumes a lot of energy. With the strengthening of national environmental protection, aircraft coatings are also faced with the requirement to reduce VOC (volatile organic compounds). Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a matching coating for the...
