Abstract
The invention provides a water-soluble polyurethane-based quick-drying base coat with an ultrahigh solid content and a production process thereof. The base coat consists of the following raw materials according to percentage by weight: 20%-40% of water-soluble polyurethane resin, 50%-65% of heavy calcium carbonate, 1%-5% of rutile type titanium dioxide, 0.4%-0.6% of thickener, 0.6%-1.0% of dispersing agent, 0.4%-0.5% of defoaming agent, 2.5%-10% of water and 0%-2% of color paste. The production process of the base coat comprises the following steps of: (1) adding the water-soluble polyurethane resin into a container; (2) adding the dispersing agent and the defoaming agent and stirring the mixture for 5 minutes; (3) adding the heavy calcium carbonate and the rutile type titanium dioxide and rapidly stirring the mixture for 20-30 minutes; (4) adding the thickener and water to adjust the viscosity and stirring the mixture for 5 minutes; and (5) adding the color paste to adjust the color for use. The base coat has the advantages of ultrahigh solid content and high drying speed, and can be applied to sealing edges of arc-shaped surfaces of medium-density fiberboards and melamine boards, as well as used as a primer instead of NC (nitrocellulose lacquer).
