The invention discloses a
coating for
coating a plastic bottom shell of a notebook computer. The
coating comprises a primer and a finish; the primer comprises a component A and a component B, and the
mass ratio of the component A to the component B is 100: (2-5); the component A is prepared from 50 to 70 parts of carboxyl-containing hyperbranched poly (amine-ester)
acrylate, 10 to 20 parts of carboxyl-terminated aromatic
hyperbranched polyester, 2 to 4 parts of functional additive and 20 to 30 parts of
solvent A; the component B is prepared from the following components in parts by weight: 60 to 80 parts of
aziridine cross-linking agent XR-100 and 25 to 35 parts of
butyl acetate; the finish paint is prepared from the following components in parts by weight: 60 to 75 parts of hyperbranched perfluorinated
polyurethane acrylate oligomer, 3 to 5 parts of 4-vinyl-2, 8-bis (
trifluoromethyl)
quinoline, 2 to 4 parts of 2, 4, 6-trivinyl boroxane, 0.1 to 0.3 part of 1-allyl-3-vinyl
imidazole chlorine salt, 4 to 6 parts of matting
powder, 0.8 to 1.2 parts of a flatting agent, 1 to 2 parts of a dispersing agent, 0.8 to 1.2 parts of an initiator and 40 to 50 parts of a
solvent B. The coating for coating the plastic bottom shell of the notebook computer, disclosed by the invention, is good in
impact strength, excellent in
wear resistance, heat and
humidity resistance, cold and hot cycle resistance and heat-resistant stability, and sufficient in
environmental protection property and
adhesive force.
