Abstract

The invention discloses polyester-amino baking enamel for roll aluminum. The polyester-amino baking enamel comprises the following components in parts by weight: 20 to 40 parts of polyester resin, 4 to 10 parts of hexamethoxy methyl melamine resin, 3 to 5 parts of a cosolvent, 2 to 4 parts of blocked waterborne isocyanate, 1 to 3 parts of a pH regulator, 0.5 to 1 part of a defoamer, 0.5 to 1.5 parts of a dispersing agent, 0.3 to 0.5 part of a base material wetting agent, 20 to 30 parts of deionized water, 0.2 to 0.4 part of a flatting agent, and 3 to 30 parts of pigment. The invention aims atproviding the polyester-amino baking enamel for roll aluminum, finally achieves the performances of high flexibility and high fullness through the improvement of the compactness of coating, and meanwhile further achieves the purposes of reducing wastewater and exhaust emission and protecting the environment.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a polyester amino baking varnish for rolling aluminum. Background technique [0002] Traditional aluminum coil paints generally use solvent-based coatings, and the dispersion medium of solvent-based coatings is organic solvents (generally referred to as VOC). Most of the organic solvents volatilized from the coating film are toxic and harmful substances, which not only cause harm to the human body , and pollute the natural environment. The invention is a water-based paint, which uses tap water as a diluent, belongs to non-hazardous chemicals, and has the characteristics of safety, environmental protection and non-toxicity. The use of water-based products not only enables users to protect employees' bodies from harmful solvents during coating construction, but also reduces users' harm to the environment, reduces the discharge of harmful exhaust gas, waste water and waste, and is...
