Abstract

The invention provides a quick-drying single-component plastic primer. The quick-drying single-component plastic primer comprises the following components in parts by weight: 30-50 parts of polyurethane modified acrylic resin, 10-20 parts of butyl acetate, 0.5-1 part of a wetting dispersant, 15-20 parts of nano barium sulfate, 18-25 parts of titanium dioxide, 0.1-1 part of hydrophobic modified fumed silica, 0.2-1 part of carbon black and 0.1-1 part of anti-settling wax. The quick-drying single-component plastic primer disclosed by the invention is easy to construct, good in appearance and leveling property, a formed paint film is flat and smooth in appearance, quick to dry, surface-dried in 5-10 minutes, excellent in adhesion to PP, ABS, nylon+glass fiber and other materials, and excellentin adhesion to upper-layer finish paint, and the paint adhesion testing adhesion is level 0-1; and hot water resistance (40 DEG C) lasts for 10 days or above. After the water resistance test, the paint adhesion testing adhesion is level 0-1. The quick-drying single-component plastic primer disclosed by the invention is good in flexibility and good in impact resistance; the plastic primer has goodadhesion on different materials, and applies the nano barium sulfate to have good water resistance.
