Coating for coating plastic bottom shell of notebook computer

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of notebook computer shell coating, in particular to a paint for coating the plastic bottom shell of a notebook computer. Background technique [0002] The bottom shell of the notebook computer is an important component of the notebook computer, and it plays the role of protecting other components and heat dissipation in the notebook computer.
