Special water-based paint for aluminium foils with hydrophilic coatings

Abstract

The invention discloses a special water-based paint for aluminium foils with hydrophilic coatings. The water-based paint comprises the following raw materials: water-based acrylic emulsion, modified amino resins, poly-butyl acrylate, a defoamer polyoxypropylene glycerol ether, calcium chloride, dioctyl sodium sulfosuccinate, epoxidized butyl oleate and butyl cellosolve. The water-based paint has the advantages that the produced water-based paint has good film-forming property; the formed films have excellent hydrophilicity, corrosion resistance, self-lubricating properties and mold-proof and antibacterial properties, serve as radiating fins of evaporators of air conditioners, eliminate surface condensation during refrigerating, obviously improve the heat exchange efficiency, reduce energy consumption, reduce noises, prolong service lives, greatly reduce spacing of fins and provide key matching technologies for high property and miniaturization oriented development of the air conditioners; and three wastes in the production and application processes of the water-based paint are reduced and the work environments of paint lines can be effectively improved.

Description

technical field [0001] The invention mainly relates to a water-based paint, in particular to a special water-based paint for hydrophilic coated aluminum foil. Background technique [0002] Traditional water-based coatings have many advantages: water-based coatings use water as a solvent, saving a lot of resources; water-based coatings eliminate the fire hazard during construction; reduce air pollution; Working environment conditions. Generally, the organic solvent (accounting for paint) of water-based paint is between 10% and 15%, but the current cathodic electrophoretic paint has dropped to less than 1.2%, which has a significant effect on reducing pollution and saving resources. Water-based coatings can be directly applied on wet surfaces and in humid environments; water-based coatings have good adaptability to material surfaces and strong coating adhesion. Water-based paint application tools can be cleaned with water, greatly reducing the consumption of cleaning solvent...

AI Technical Summary

Problems solved by technology

[0003] However, traditional water-based coatings also have many disadvantages: Water-based coatings have high requirements on the cleanliness of the construction process and the surface of the material. Due to the high surface tension of water, dirt is easy to cause shrinkage cavities in the coating film; water-based coatings are stable against strong mechanical forces. Poor performance, when the flow rate in the pipeline changes sharply, the dispersed particles are compressed into solid particles, causing pitting in the coating film

Water-based paint has the problem of poor water resistance, which makes the stability of the paint and bath solution poor, and the water resistance of the coating film is poor
