Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of U.S. Provisional Application No. 63 / 241,573, entitled "Aqueous Surface Treatment Composition," filed September 8, 2021, the disclosure of which is incorporated herein by reference in its entirety.

[0002] The present invention relates to aqueous surface treatment compositions, and more particularly to aqueous surface treatment compositions containing aminosilicones, surface treatment agents and coatings formed therefrom, and surface treatment methods using the same. [Background technology]

[0003] Water-based coatings are of interest due to their environmentally favorable profile compared to solvent-based coatings, which may use volatile organic solvents. However, solvent-based coatings tend to exhibit better performance and durability compared to water-based coatings. One approach to improving the performance of water-based coatings is to modify the design of the base resin.

[0004] Another approach to improve the performance of water-based coatings is to use additives that work in conjunction or synergy with the water-based resin. Silicones are used in coatings to treat hard surfaces. Coatings for hard surfaces are typically solvent-based systems. Using silicones in water-based systems is generally more difficult than in solvent-based systems. Typical silicones may require the use of large amounts of surfactants to make them compatible with water-based resins. However, using large amounts of surfactants may reduce the elasticity of the water or lead to leaching of the surfactant from the coating. Silicone polyethers have good compatibility with acrylic latexes and can increase the slip of the coating, but silicone polyethers have limited durability and hydrophobicity. Silicone rubbers (e.g., polydimethylsiloxane) can increase slip at very low concentrations. However, silicone rubbers tend to cause craters and other defects in the film and are difficult to use to increase water repellency when used in high concentrations. In addition, it is preferable that the use of silicone additives does not significantly affect the finish of the coating, such as glossy or matte finishes. Thus, there is a need for silicone-based aqueous surface treatment compositions that have improved properties, such as durability and hydrophobicity, without introducing defects or significantly affecting properties such as gloss, especially when used in high concentrations.

[0083] Aspects of the present technology may be further understood with reference to the following examples, which are intended primarily to illustrate aspects of the technology and are not intended to limit the technology to the specific embodiments illustrated by the examples.

[0084] Working Example

[0085] Paint preparation: The coating compositions were prepared by standard mixing techniques as described in Organic Coatings: Science and Technology, Z. Wicks, F. Jones and P. Pappas, Eds., Wiley-Interscience Publishers, 1998, Chapter 31, Architectural Coatings, which is incorporated herein by reference in its entirety.

[0086] Preparation of coating samples: The paints were applied to glass slides or steel plates using a Bird-type applicator with a 75 micrometer gap and allowed to dry at room temperature for one week. The plates and steel plates were cleaned with IPA prior to application of the paint.

[0087] Static water contact angle: Water contact angles were measured using a VCA Optima instrument. A 4 microliter drop of Millipore water was generated by a Hamilton syringe and deposited on the paint coating. A video was recorded to capture the drop after contact. The reported contact angle is the average of the contact angles of three drops.

[0088] Dynamic friction coefficient: The dynamic friction coefficient was measured using a friction and wear tester manufactured by CSM, using a linear reciprocating stroke with an amplitude of 0.5 mm, a stainless steel ball (diameter 5 mm), a load of 2 N, and a sliding speed of 1 cm / sec.

[0089] Dynamic contact angle:The water dynamic contact angle and oil dynamic contact angle were measured with a Thermo Fisher Cahn DCA322 microbalance. The paint was applied using a sponge applicator on both sides of a Renata black scrub test panel cut to a rectangular size of 1 inch by 1.5 inches. The dry film thickness of the paint was approximately 50 micrometers. The speed and total depth of immersion of the sample were 80 micrometers / second and 8 mm, respectively. The initial surface tension of the water before measuring the water dynamic contact angle using a platinum Wilhelmy plate was equal to 72 mN / m. After immersion and withdrawal of the paint sample, the surface tension of the water after immersion of the sample was measured to quantify the leaching of the surfactant or surface active material into the water. The oil used for the oil contact angle was soybean oil Agri-Pure 25 from Cargill. The surface tension of soybean oil was 33 mN / m.

[0090] Crater formation was assessed visually.

[0091] Example I: Water-based acrylic paint

[0092] The water-based coating composition is shown in Table 1. Hydroplat WE3111 is a wetting agent manufactured by BASF. Dispex CX4230, Dispex AA4144 are dispersants manufactured by BASF. Foamstar ST2438, Foamstar ST2420 are defoamers manufactured by BASF. Rheovis PU1191, Rheovis PU1331 are polymeric rheology modifiers manufactured by BASF. Attagel 50 is a clay-based rheology modifier. Titanium oxide pigments Ti-Pure R902 and R746 are manufactured by DuPont. Minex-7 is manufactured by Unimin Specialty Minerals. Texanol is a flocculant manufactured by Eastman. Proxel BD20 is a preservative manufactured by Lonza. Acronal 4230PLUS is an all-acrylic latex with a minimum filming temperature of 6°C and 60% solids manufactured by BASF.

[0093] The comparative silicone emulsion is a 50% solids emulsion of dimethiconol silicone rubber emulsion, produced by emulsion polymerization and stabilized with sodium lauryl sulfate and sodium lauryl ether sulfate, the viscosity of the silicone rubber is in the range of 350,000 to 700,000 mPa·s, as measured on a Brookfield viscometer LVDV with spindle #4 at 0.3 rpm at 25°C.

[0094] Silicone Emulsion A is a 45% weight percent solids emulsion of an alkylamino silicone stabilized with a nonionic surfactant. The alkylamino silicone is modified at both ends and is represented by formula (I), where x is 650, y is 3.5, R 1 is an alkyl group having 16 to 18 carbon atoms; R 2 , R 3 , and R 4 are methyl and R 5 is an N-(2-aminoethyl)-3-aminopropyl group. The aminosilicone was emulsified with a mixture of nonionic surfactants selected from ceteareth-7 and ceteareth-21. The aminosilicone had a viscosity of about 5000 to about 20,000 mPa s. The viscosity was measured on a Brookfield viscometer LVDV with spindle #4 at 30 rpm.

[0095] [Table 1]

[0096] The alkyl-terminated amino silicones provide increased hydrophobicity compared to silicone rubber emulsions. At a concentration of 3% by weight, the alkyl-terminated amino silicone emulsions provide both reduced friction and increased hydrophobicity without producing film defects or significantly affecting gloss.

[0097] Example II: Clear Acrylic Coating

[0098] The acrylic compositions shown in Table 2 were applied to glass slides using a Bird-type applicator and allowed to dry at room temperature for one week. Rhoplex AC261 is an all-acrylic latex manufactured by Dow with a minimum film forming temperature of 16°C. Nalco 1050 colloidal silica has a particle size of 20 nm. Silicone Emulsion A and comparative emulsions are described in Example I.

[0099] [Table 2]

[0100] The alkyl-terminated amino silicones provide increased hydrophobicity compared to the comparative emulsion. Even at a concentration of 0.3 wt%, Silicone Emulsion A significantly reduces the dynamic coefficient of friction (Example 8) compared to the comparative coating (Comparative Example 10). Example III: Dynamic Contact Angle and Surfactant Leaching Tests The coatings of Example I (Comparative Example 3, Example 4, and Comparative Example 5) were applied and dried on black Reneta scrub test panels (Foam P121-10N, black plastic-vinyl chloride / acetate copolymer). The advancing dynamic water contact angle and the dynamic contact angle of soybean oil of the coating films were measured to evaluate hydrophobicity and oleophobicity. Leaching of surface active materials from the coating into the water phase was evaluated by measuring the surface tension of the water before and after immersion of the coating samples. The lower the surface tension, the worse the surfactant leaching (Reference: P. Santos et al., Low VOC Coalescents. Coatings World - Technical Papers, p2019, https: / / www.coatingsworld.com / issues / 2019-2008-2001 / view_technical-papers / low-voc-coalescents).

[0101] [Table 3]

[0102] The advancing water contact angles for the coating containing the alkyl-terminated aminosilicone are higher than those for the coating containing the comparative emulsion.

[0103] The comparative paint (Comparative Example 11) leaches surface active material into the water, as indicated by the surface tension decreasing from an initial value of 72 mN / m in clean water.

[0104] The alkyl-terminated aminosilicone does not result in any significant additional release of surface active material, whereas the comparative silicone emulsion further reduces the surface tension of water.

[0105] The increase in advancing oil contact angle for the alkyl terminated aminosilicone is significantly higher than that for the comparative emulsion, indicating a better oleophobic effect of the alkyl terminated aminosilicone emulsion than that of the comparative emulsion.

[0106] Example III: Water-Based Acrylic Paint

[0107] The water-based coating compositions are shown in Table 4. Hydroplat WE3105 is a wetting agent from BASF. Dispex AA4146 is a dispersing agent from BASF. Foamstar ST2410 is a defoamer from BASF. Rheovis PU1250 is a polymeric rheology modifier from BASF. Titanium dioxide pigment Ti-Pure R902 is from DuPont. Texanol is a flocculant from Eastman. IPEL BP-503 is a preservative from IPEL. Acronal 4670PLUS is an all-acrylic latex with a minimum filming temperature of 10°C and 50% solids from BASF.

[0108] The comparative silicone emulsion is a 50% solids emulsion of dimethiconol silicone rubber emulsion prepared by emulsion polymerization and stabilized with sodium lauryl sulfate and sodium lauryl ether sulfate, the viscosity of the silicone rubber is in the range of 350,000 to 700,000 mPa·s, as measured on a Brookfield viscometer LVDV using spindle #4 at 0.3 rpm at 25°C.

[0109] Silicone Emulsion A is a 45% weight percent solids emulsion of an alkylamino silicone stabilized with a nonionic surfactant. The alkylamino silicone is modified at both ends and is represented by formula (I), where x is 650, y is 3.5, R 1 is an alkyl group having 16 to 18 carbon atoms; R 2 , R 3 , and R 4 are methyl and R 5 is an N-(2-aminoethyl)-3-aminopropyl group. The aminosilicone was emulsified with a mixture of nonionic surfactants selected from ceteareth-7 and ceteareth-21. The aminosilicone had a viscosity of about 5000 to about 20,000 mPa s. The viscosity was measured on a Brookfield viscometer LVDV with spindle #4 at 30 rpm.

[0110] The abrasive scrub resistance test was performed according to ASTM 2486 (Method A) and the test was performed in duplicate.

[0111] Blocking resistance test:The paint was applied to a black matte plastic panel (Reneta P-121-10N) using a film applicator with 7 mil clearance and allowed to dry at room temperature for 7 days. The plastic panel was cut into a 2" x 2" square. Two pieces were placed with the painted sides facing each other. The facing specimens were placed in a 50°C oven. A 1000 gram cylindrical weight (radius = 2 cm) was placed on the specimen and held at 50°C for 2 minutes. The contact pressure on the specimen was approximately 80 grams / cm. 2 After cooling, the facing specimens were peeled apart. The panels were rated based on visual inspection. The degree of block resistance was rated on a scale of 10 to 0. This block resistance rating is described in ASTM D4946. The degree of seal is an estimate of the area on the specimen where the paint on the surfaces is adhered to each other. A rating of 10 indicates no adhesion or seal. A rating of 1 indicates a seal of 50% to 75%. This test was performed in triplicate.

[0112] Surfactant Leaching Test Method: The paints were applied to black matte plastic panels (Reneta P-121-10N) using a film applicator with 7 mil clearance and allowed to dry for 2 hours at room temperature. Three drops of water, each approximately 0.1 cc in volume, were placed on the test paint and allowed to remain for 10 minutes. The panel was raised to a vertical position, allowing the water drops to run off, and then allowed to dry vertically overnight at room temperature. The panels were rated based on visual inspection.

[0113] [Table 4]

[0114] The aminosilicone emulsion at a concentration of 2.9 wt.% provided increased blocking resistance (Example 11) compared to the base paint without silicone (Comparative Example 12). In addition, the example paint with the alkyl-terminated aminosilicone emulsion (Example 11) provided much less surfactant bleed than the base paint (Comparative Example 12) and the comparative paint with the silicone rubber emulsion (Comparative Example 13). Figures 1 to 3 are photographs of the paint panels used in the surfactant bleed test. Figure 1 is the panel with Comparative Example 12 and shows large visible water streaks. Figure 2 is the panel for Comparative Example 13 and shows small visible water streaks. Figure 3 is the panel for Example 11 and shows minimal water streaks. In addition, the alkyl-terminated aminosilicone emulsion did not significantly reduce the abrasion scrub resistance of the paint, whereas the comparative silicone rubber emulsion reduced the abrasion scrub resistance very significantly.

[0115] Example IV: Polyurethane Dispersion Clearcoat

[0116] The clearcoat compositions are shown in Table 5. Bayhydrol UH2953 / 1 is an aliphatic, fatty acid modified anionic polyurethane dispersion, 34.5% by weight solids, manufactured by Covestro. Di(propylene glycol) propyl ether or Dowanol DPnP is a flocculant manufactured by The Dow Chemical Company. BYK346 is a wetting agent manufactured by BYK. BYK028 is a defoamer manufactured by BYK. Aquaflow TM NHS300 is a rheology modifier manufactured by Ashland.

[0117] The compositions were prepared in an IKA Laboratory Technology RW16 Basic Overhead Mixer. The water and flocculant solvent were premixed at low mixing speed (approximately 100 RPM). The water / flocculant premix, polyurethane dispersion, wetting agent, defoamer, silicone emulsion, rheology modifier, and additional water were added to the main vessel of the mixer and mixed together at medium speed (approximately 600 RPM) for 15 minutes. The compositions were then mixed at high mixing speed (approximately 1200 RPM) for 5 minutes. The compositions of Example IV (Comparative Example 14, Example 12) were applied to glass slides using a film applicator to form a 10 mil thick wet film and allowed to dry. The static water contact angles in Table 5 are the average of five measurements.

[0118] [Table 5]

[0119] The example formulation using an alkyl-terminated aminosilicone (Example 12) exhibited increased hydrophobicity compared to the comparative formulation (Comparative Example 14), as indicated by the high water contact angle value (106°).
