Abstract

The invention discloses a weatherproof noctilucent paint for aluminum coating. The weatherproof noctilucent paint comprises, by weight, 10-25 parts of modified aluminate alkaline earth metal noctilucent pigment, 0.3-0.8 part of fluorescent pigment, 30-40 parts of fluorocarbon resin, 1-3 parts of ethylene glycol, 1-2 parts of film-forming assistant texanol, 5-10 parts of calcium carbonate, 1-7 parts of silicone oil, 10-15 parts of titanium dioxide, 10-25 parts of a curing agent, 1-3 parts of an anti-settling agent, 1-5 parts of a dispersant and 1-2 parts of a defoaming agent. The invention also discloses a use method. The noctilucent paint has good weather resistance and high hardness, the added fluorescent pigment takes the paint apparent color and luminous effect into account, a reflective substrate with a white underlayer is conducive to improving the of luminous effect of a noctilucent coating, a volatile substance harmless to the human body is adopted as the solvent, and the hot coating process has no harm to the operation staff, and is more environmentally friendly.

Description

technical field [0001] The invention relates to a weather-resistant luminous paint for coating aluminum and a use method thereof. Background technique [0002] Coated aluminum is also known as sprayed aluminum, coated aluminum coil, and sprayed aluminum coil. The preparation process is generally cleaning (removing a layer of lubricating oil, anti-oxidation grease and various dirt attached to the surface of the aluminum coil during rolling) → chemical formation (adding chemical raw materials to form an oxide film on the surface of the aluminum coil) → coating → baking bake. In the painting process, the paint or paint of the corresponding color is painted according to the customer's requirements. At present, some luminous painted aluminum is favored by merchants, so it is gradually becoming popular to apply luminous paint on the surface of the formed aluminum coil. Luminous pigments have poor water resistance (weather resistance) and are unstable to water. Even the moisture ...
