Description
[technical field]
The present invention relates to film packing material technical field, specifically a kind of that there is velvet, anti-scratch aqueous polyurethane coating.
[background technology]
In recent years, aqueous polyurethane feel coating was widely used in packages printing field.Wherein, some can provide the coating of excellent resilient flexible sense of touch generally to have the defect of resistance to marring, weathering resistance, chemicals-resistant difference, cause gloss to weaken, cut is obvious, and elastic tactility that some coating with the resistance to marring of improvement has is not enough, thus have a strong impact on film quality and attractive in appearance.Therefore, scratch resistance there is good sense of touch become the important indicator weighing aqueous polyurethane coating performance.And with high scratch resistance and good sense of touch, then mean and material surface can be made to keep gloss and attractive in appearance in a long time, and make the materials'use life-span longer.
[summary of the invention]
Object of the present invention is exactly will solve above-mentioned deficiency and provide a kind of that have velvet, anti-scratch aqueous polyurethane coating, and this aqueous polyurethane coating has excellent scratch resistant performance and good sense of touch, is mainly used in film packing material.
Design a kind of that have velvet, anti-scratch aqueous polyurethane coating for achieving the above object, this aqueous polyurethane coating is by weight percentage, composed of the following components:
Organo-siloxane, by the silicone resin of hydroxyl or amido or monomer and di-isocyanate reaction, is guided in aqueous polyurethane, is utilized the crosslinking of organo-siloxane to improve Property of Waterborne Polyurethane by described polysiloxane-modified polyurethane dispersions.
Described acrylate modified polyurethane dispersions is obtained by two prepolymer method, and the number-average molecular weight of described acrylate modified polyurethane dispersions is 1000-2000.
Aluminum oxide in described water nano alumina fluid dispersion is alpha-phase aluminum oxide, and the particle diameter of described alpha-phase aluminum oxide is 5-30nm.
The particle diameter of described alpha-phase aluminum oxide is 20-40nm.
The particle diameter of described polyurethane foam elasticity pearl is 3-8 μm.
Described thickening material is association type polyurethane thickener.
Described defoamer is molecular level acetylenediol defoamer, and described defoamer has 2 hydrophilic groups and 2-3 hydrophobic group.
Described solidifying agent is aziridine hardener.
This has the preparation method of velvet, anti-scratch aqueous polyurethane coating, comprise the following steps: by above-mentioned weight percent, take each component, polysiloxane-modified polyurethane dispersions, acrylate modified polyurethane dispersions, water nano alumina fluid dispersion, polyurethane foam elasticity pearl and defoamer are joined stirrer for mixing, and then add thickening material and solidifying agent, stir at least 30 minutes with 400-600 rev/min, mix, namely obtain that there is velvet, anti-scratch aqueous polyurethane coating.
The present invention compared with the existing technology, by choosing polysiloxane-modified polyurethane dispersions, acrylate modified polyurethane dispersions, water nano alumina fluid dispersion, polyurethane foam elasticity pearl, defoamer, thickening material and solidifying agent are raw material, select suitable aqueous polyurethane dispersion and coatings additive(s), and the scientific matching passed through formulation for coating material and optimization, thus configure and a kind of both there is good sense of touch, weathering resistance, there is again excellent scratch resistance and anti-scratch aqueous polyurethane coating, this coating can be mainly used in film packing material, the film formed at substrate surface after paint solidification has scratch resistance and good sense of touch, be worthy of popularization.
[embodiment]
The invention provides a kind of that there is velvet, anti-scratch aqueous polyurethane coating, this aqueous polyurethane coating is by weight percentage, composed of the following components: acrylate modified polyurethane dispersions 40-60%, the water nano alumina fluid dispersion 0.5-5% of the polysiloxane-modified polyurethane dispersions 20-40% of at least one, at least one, polyurethane foam elasticity pearl 1-8%, thickening material 0.5-15%, defoamer 0.1-1%, solidifying agent 1-5%.The preparation method of this aqueous polyurethane coating, comprise the following steps: by above-mentioned weight percent, take each component, polysiloxane-modified polyurethane dispersions, acrylate modified polyurethane dispersions, water nano alumina fluid dispersion, polyurethane foam elasticity pearl and defoamer are joined stirrer for mixing, and then add thickening material and solidifying agent, stir at least 30 minutes with 400-600 rev/min, mix, namely obtain that there is velvet, anti-scratch aqueous polyurethane coating.
Wherein, organo-siloxane, by the silicone resin of hydroxyl or amido or monomer and di-isocyanate reaction, is guided in aqueous polyurethane, is utilized the crosslinking of organo-siloxane to improve Property of Waterborne Polyurethane by polysiloxane-modified polyurethane dispersions.Acrylate modified polyurethane dispersions is obtained by two prepolymer method, and have good weathering resistance, snappiness, its number-average molecular weight is 1000-2000.Aluminum oxide in water nano alumina fluid dispersion is alpha-phase aluminum oxide, and the particle diameter of alpha-phase aluminum oxide is 5-30nm.The particle diameter of alpha-phase aluminum oxide is 20-40nm.The particle diameter of polyurethane foam elasticity pearl is 3-8 μm.Thickening material is association type polyurethane thickener.Defoamer is molecular level acetylenediol defoamer, and defoamer has 2 hydrophilic groups and 2-3 hydrophobic group, has foam control agent and the defoamer of wettability concurrently.Solidifying agent is aziridine hardener, adds before use, with 400-600 rev/min, stirs more than 30 minutes.
