Abstract

The invention discloses an aluminum alloy colored plate primer and a preparation method thereof, and aims to provide an aluminum alloy colored plate primer with high product adhesion, favorable flexibility and smooth paint film. The technical scheme is as follows: the primer is prepared from the following components in percentage by mass: 20-27% of polyester resin, 0.4-0.6% of antisettling assistant, 4-6% of solvent, 15-25% of tetramethylbenzene, 3-7% of titanium white, 20-30% of filler, 4-6% of epoxy resin, 4-6% of amino resin, 0.4-0.6% of leveling agent and 0.4-0.6% of hard drying agent. The aluminum alloy colored plate primer belongs to the technical field of paints.

Description

technical field [0001] The invention relates to a paint formula, in particular to an aluminum alloy color plate primer, and also relates to a preparation method of the aluminum alloy color plate primer; it belongs to the technical field of paint. Background technique [0002] Color plate primer is a kind of paint used for the surface coating of aluminum alloy plate, which plays the role of decoration and protection. It not only requires excellent adhesion with the primer, but also can beautify the visual effect of the product and protect the substrate from environmental and other factors affecting the service life. At present, the topcoat used in coil coating generally adopts the following raw materials in its formulation: ordinary saturated polyester, ordinary amino resin, pigment, additive, and solvent. After the above raw materials are blended, they are processed according to the conventional coil coating production process through processes such as dispersion, grinding,...
