(3) preparation of the hydrophilic aluminium foil coating of bottom surface unification
Successively hydrophilic acrylic resin, polyurethane acrylic resin, reactive thinner are added in stirrer by proportioning claimed in claim 1, be under 1500～2500 revs/min, to stir 15～30 minutes at rotating speed, and then add light trigger, under the rotating speed of 1000～2000 revs/min, stir 10～15 minutes, obtain the hydrophilic aluminium foil coating of desired bottom surface unification.
Curing mode of the present invention is: first base material aluminium foil is carried out to pre-treatment, pre-treatment comprises cleans base material aluminium foil surface and base material aluminium foil is carried out to drying and processing with the mixed solution of grease-removing agent and deionized water; After pre-treatment, the coating of preparation is filled with to paint roller, by the rotation of paint roller, coating is coated in to the two surfaces of base material aluminium foil bag uniformly, the coating applying on base material aluminium foil is controlled at 1g/m
2left and right; The high voltage mercury lamp ultraviolet light irradiation that is 1kw through overpower solidifies for 30 seconds, finally can obtain hydrophilic aluminium foil coating.
Advantage of the present invention and beneficial effect are mainly:
1, hydrophilic aluminium foil coating of the present invention, bottom surface unification, solidifies by ultraviolet light irradiation, the complete processing that dry at two ends two of needs of relatively traditional hydrophilic aluminium foil, work simplification and energy saving, in addition, coating has reduced the volatilization of organic solvent, is conducive to environmental protection.
2, the protracted hydrophilicity of the bottom surface unified hydrophilic aluminum foil coating by ultraviolet light irradiation is strong, and hardness is moderate, and sticking power is good, less to the wearing and tearing of punching die, and anticorrosion effect is better.
Background technology
Hydrophilic aluminium foil is the modified aluminium foil material that makes to solidify in pure aluminum foil surface-coated hydrophilic coating by special process.Water of condensation can scatter rapidly on hydrophilic aluminium foil, can not condense into the globule, thereby increases heat exchange area, accelerates cooling and warming speed, also can effectively avoid water of condensation to hinder air flowing and the noise that produces.Based on this, class hydrophilic coating material for aluminium foil requires to have following performance: 1, good wetting ability and resistance to corrosion; 2, good plasticity and to the non-abradability of mould; 3, extremely strong resistance to punching press oiliness, solvent resistance, heat impedance; 4, gas-flow resistance is little.Traditional hydrophilic aluminium foil applying coating, comprises primer coating and hydrophilic surface lacquering, need to have the process of twice application and baking.In addition, traditional hydrophilic aluminium foil coating, in coating process, is mainly by the volatilization of water and organic solvent, and heating film forming is solidified.On the one hand, the volatilization of a large amount of organic solvents is unfavorable for environmental protection; On the other hand, the power consumption that is heating and curing is large, and baking time is longer, and production efficiency declines.
For overcoming the defect of traditional hydrophilic aluminium foil coating.The present invention is by synthesis hydrophilic based acrylic resin, and mixed polyurethane acrylic resin, reactive thinner and light trigger, prepare the hydrophilic aluminium foil coating of a kind of novel bottom surface unification, it solidifies by ultraviolet light irradiation mode, abandon solvent evaporates and pollute to reduce, enhance productivity simultaneously.Coating resin itself is with hydrophilic radical, and paint film has protracted hydrophilicity, and mechanical property is better, and corrosion resistance nature is strong, the complete Application Areas applicable to hydrophilic aluminium foil.
Summary of the invention
The object of the invention is the defect in order to overcome traditional hydrophilic aluminium foil coating, hydrophilic aluminium foil coating of a kind of bottom surface unification and preparation method thereof is provided.
