Description

POLYMERS WITH SILICON-CONTAINING SIDE CHAINS AND COATING

COMPOSITIONS INCLUDING THESE POLYMERS

TECHNICAL FIELD

[0001] This relates to a novel polymer, and a coating composition of the polymer.

BACKGROUND

[0002] Wood, glass, ceramics, masonry and metal are widely utilized in the constructions of buildings and building products such as windows, floors, furniture, doors and fences in view of their advantages of easy processing, high strength and relatively low cost. It is also well known that these materials are generally porous on structures and easily soaked by liquids. In some cases, they could deteriorate under the influence of outdoor environment (e.g., rain, snow, ultraviolet (UV) lights), or fade in colour over time (e.g. by virtue of spill of beverages, oils). After a period of time, they can become spotted in appearance, lose mechanical strength or undergo dimensional change. The latter two types of deterioration also cause safety concerns. To mitigate this, it is common to coat or treat their surfaces with water- repellant coatings or paints. Additionally, some materials, such as glass and fabrics, have a self-cleaning requirement, and other materials, such as steel, have anti-corrosion requirements, and water proofing coatings are often applied to such materials so as to satisfy these requirements.

[0003] In general, slack wax, polytetrafluoroethylene (PTFE) or silicone has been used as a coating material. Slack wax is widely used because of its advantages of relatively low price, safe to use and ease of processing. Woods and bricks can be quickly treated by slack wax, which provides them with shiny and water repellent surfaces. Also, waxed surfaces

DOCSTOR: 2656202\1 significantly reduce water absorption (U.S. Pat. App. No. 20100249283; U.S. Pat. No. 2231486; U.S. Pat. No. 4360385). However, the drawback is that excessive amounts of slack wax reduces the bonding action between material elements and make subsequent operations more difficult. Additionally, the treated surfaces (e.g., floor) may pose a slippery hazard. Slack wax is also difficult to bond to some substrates, and has a low melting point (less than 70 °C), rendering it inappropriate for certain applications.

[0004] A potential alternative is a varnish, such as polyurethane, which has better hardness, transparency and durability. However, the drawback is that it strongly absorbs UV irradiation, which can cause premature degradation. The varnish film tends to become brittle and can be easily peeled off substrates. Also, the varnish film is also transparent to UV light. In this respect, colors present in varnished substrates, such as wood and brick, are susceptible to fading (J. Paint Tech., 531 (41) 275, 1969).

[0005] Polytetrafluoroethylene ("PTFE") is famous for its non-stick, high water- repellent properties, and is widely used in coating application (U.S. Pat. No. 3055852; U.S. Pat. No. 4857578). However, it suffers from poor solubility in solvents. One approach to resolve this issue is to disperse PTFE particles and other film-forming agents in an organic solvent. In this way, PTFE becomes embedded in the final coating as it is cured. However, with this method, there is a concern about uniformity of the final coatings. Another approach is using water-based PTFE production, (i.e., PTFE emulsion), which works well on bricks and masonry, but is less compatible with woods. This is because the surfactants used in emulsion are difficult to remove from the woods, resulting in a more hydrophilic final coating. Additionally, perfluorooctanoic acid (PFOA), the surfactant in producing PTFE, is a carcinogen. The byproduct of PTFE decomposition is also a health concern, and can cause flu- like symptoms in humans (DuPont, Key Questions about Teflon, accessed on 3 December 2007).

[0006] Apart from PTFE, silicone and silicon-based compounds are also known as low surface energy materials. For examples, JP-A 63-265601 discloses an impregnating method, where silicone polymers are formed within cell walls of woods. This method appears to be effective for prohibiting water absorption, but less effective for improving dimensional stability. U.S. Pat. No. 7658972 discloses a silicone emulsion for waterproofing woods, wherein the main component of emulsion is organopolysiloxane, and such emulsion is cured by the reaction between amino and epoxy. Organosilane quaternary nitrogen compounds have also been employed effectively for imparting water and various stains, as described in U.S. Pat. No. 7589054; U.S. Pat. No.7658972. Silicone products have significant advantages of flexibility, transparency, and resistance to extreme temperatures (-55°C to +300°C). One concern about silicone products is their lack of mechanical strength. Additionally, the low surface energy property of silicone product can cause poor bonding with substrates.

[0007] Until now, studies on superhydrophobic surfaces have attracted much attention.

A superhydrophobic surface, upon which the static water contact angle is more than 150°, and the sliding angle is less than 5°, may generally be prepared by the combination of low surface energy materials and the appropriate surface roughness ((a) T. Onda, S. Shibuichi, N. Satoh, K. Tsujii, Langmuir 1996, 12, 2125. (b) T. Tsujii, T. Yamamoto, T. Onda, S. Shibuichi Angew. Chem. nt. Ed. Engl. 1997, 36, 101 1. (c) J. P. Youngblood, T. J. McCarthy Macromolecules 1999, 32, 6800. (d) X. Feng, Jiang, L. Adv. Mater. 2006, 18, 3063.). However, these superhydrophobic surfaces require special designs on the surface structures, which are not suitable for materials with original complicated surface structures like wood or ceramic tiles, and also not suitable for materials with a transparency requirement, such as glass.

[0063] METHOD OF MAKING THE OPERATIVE POLYMER

COATING COMPOSITION

[0074] There is also provided a coating composition comprising an operative polymer material and an operative solvent material. The operative polymer material consists of one or more of the operative polymers described above. The operative solvent material consists of one or more operative solvents. The operative solvent is configured to solubilize at least a fraction of any amount of the operative polymer material. In some embodiments, for example, substantially all of the operative polymer material is dissolved within the operative solvent material.

[0075] In some embodiments, for example, within the coating composition, the ratio of the weight of operative polymer material to the weight of the operative solvent material is between 4:1 and 1 :100,000. In some embodiments, for example, within the coating composition, the ratio of the weight of operative polymer material to the weight of the operative solvent material is between 1 :10 and 1 : 10,000. In some embodiments, for example, within the coating composition, the ratio of the weight of operative polymer material to the weight of the operative solvent material is between 1 :20 and 1 : 1 ,000.

[0076] In some embodiments, for example, the operative polymer has a weight average molecular weight (Mw) of between 2000 and 1 ,000,000, a number average molecular weight (Mn) of between 2000 and 1 ,000,000, and a polydispersity index (Mw/Mn) between 1 and 10. In some embodiments, for example, the operative polymer has a weight average molecular weight (Mw) of between 10,000 and 500,000, a number average molecular weight (Mn) of between 10,000 and 500,000, and a polydispersity index (Mw/Mn) of between 1 and 7. In some embodiments, for example, the operative polymer has a weight average molecular weight (Mw) of between 50,000 and 500,000, a number average molecular weight (Mn) of between 50,000 and 500,000, and a polydispersity index (Mw/Mn) of between 1 and 5.

[0077] In some embodiments for example, the operative solvent functions to solubilize the operative polymer for facilitating its transport into contact engagement relationship with, and adhesion to the substrate. Suitable exemplary operative solvents include toluene, xylene, ethyl acetate, tetrahydrofuran, acetone, and ethanol.

[0078] In some embodiments, for example, the coating composition further includes a catalyst material.

[0079] In some embodiments, for example, the coating composition includes: (i)

0.0001 to 20 weight percent of the operative polymer material, based on the total weight of coating composition, and (ii) l x lO^"9 to 1 weight percent of the catalyst material, based on the total weight of the coating composition, and (iii) 80 to 99.9999 weight percent of the operative solvent material, based on the total weight of the coating composition. In some embodiments, for example, the coating composition includes (i) 0.01 to 10 weight percent of the operative polymer material, based on the total weight of the coating composition, and (ii) 1 ^χ 10^"5 to 1 weight percent of the catalyst material, based on the total weight of the coating composition, and (iii) 89-99.98999 weight percent of the operative solvent material, based on the total weight of the coating composition.

[0080] In some embodiments, for example, the catalyst material effects hydrolysis and coupling of siloxane groups to the substrate. In some embodiments, for example, the substrate includes hydroxyl groups that react with the siloxane groups in a hydrolysis reaction, [0081] In some embodiments, for example, the catalyst material includes an organotin compound. In some embodiments, for example, the catalyst material includes dibutyltin dilaurate.

[0082] In some embodiments, for example, the coating composition may, but not necessarily, additionally include other materials, such as fillers, extenders, dispersants, surfactants, and pigments. In some of these embodiments, such other materials are present within the coating compositions in amounts that do not materially adversely affect the solubility of the operative polymer material within the operative.

USE OF COATING COMPOSITION

[0083] The coating composition is applied to a substrate so as to effect contact engagement relationship between the coating composition and the substrate. Such application includes that effected by deposition of the coating composition on the substrate, or by coating of the substrate with the coating composition. In response to the contact engagement relationship, production is effected of a material layer (or "film") that is adhered to the substrate.

[0084] In some embodiments, for example, the application of the coating composition on the substrate includes that by brushing, brush painting, spraying, or dipping.

[0085] In some embodiments, for example, the adhesion of the material layer is to at least a portion of the surface material of the substrate. In some embodiments, for example, the adhesion of the material layer is to at least a portion of the substrate surface material and also to a portion of the substrate disposed below the substrate surface material of the substrate. The adhesion to a portion of the substrate disposed below the substrate surface material is effected after the application of the coating composition to the substrate, and after the applied coating composition has penetrated the substrate through an opening in the substrate surface material of the substrate so as to become disposed in contact engagement relationship with a subsurface portion of the substrate.

[0086] In some embodiments, for example, the adhesion includes chemical bonding between the material layer and the substrate. In some of these embodiments, for example, the chemical bonding is effected by the hydrolysis reaction between siloxane groups of the operative polymer and the hydroxyl groups of the substrate. In some embodiments, for example, the adhesion includes physical adhesion between the material layer and the substrate. For example, physical adhesion or attachment may occur between the operative polymer and a substrate surface which is metallic.

[0087] It is understood that one or more portions of the substrate, including the surface of the substrate, may become modified, (physically, or chemically, or both physically and chemically) in response to, at least, the contact engagement of the coating composition with the substrate. The term "substrate" is intended to cover the substrate prior to such contact engagement, as well as any modified form it assumes in response to such contact engagement. As well, the term "substrate surface material" is intended to cover the substrate surface material prior to such contact engagement, as well as any modified form it assumes in response to such contact engagement.

[0088] In some embodiments, for example, the contacting of the coating composition with the substrate is effected by applying the coating composition onto a substrate surface material of the substrate, and the substrate surface material of the substrate is relatively less hydrophobic than the operative surface material whose production is effected by, at least, the contacting of the coating composition with the substrate. In some embodiments, for example, the operative surface material is configured for interacting with a water droplet disposed on the operative surface material, such that, under the same environmental conditions, the contact angle of the operative surface material-disposed water droplet is greater than the contact angle of a water droplet disposed on the substrate surface material of the substrate.

[0089] In some embodiments, for example, after the application of the coating composition, the applied coating composition is cured so as to effect production of a cured material layer (or "film"). Curing includes evaporation of the operative solvent material. In some embodiments, for example, the curing includes the supply of an artificial heat input.

[0090] In some embodiments, for example, the contact angle of a water droplet on the operative surface material of the cured material layer in ambient air at a temperature of 20 degrees Celsius, at a pressure of one (1) atmosphere, and at a relative humidity of between 30 percent and 50 percent, is greater than 90 degrees. In some embodiments, for example, the contact angle of a water droplet on the operative surface material in ambient air at a temperature of 20 degrees Celsius, at a pressure of one (1) atmosphere, and at a relative humidity of between 30 percent and 50 percent, is greater than 1 10 degrees. In some embodiments, for example, the contact angle of a water droplet on the operative surface material in ambient air at a temperature of 20 degrees Celsius, at a pressure of one (1 ) atmosphere, and at a relative humidity of between 30 percent and 50 percent, is greater than 120 degrees. In some embodiments, for example, the contact angle of a water droplet on the operative surface material in ambient air at a temperature of 20 degrees Celsius, at a pressure of one (1 ) atmosphere, and at a relative humidity of between 30 percent and 50 percent, is greater than 150 degrees. [0091] In some embodiments, for example, the sliding angle of a water droplet, having a volume of between 20 μΐ to 30 μΐ, on the operative surface material of the cured material layer in ambient air at a temperature of 20 degrees Celsius, at a pressure of one (1) atmosphere, and at a relative humidity of between 30 percent and 50 percent, is less than 80 degrees. In some embodiments, for example, the sliding angle of a water droplet, having a volume of between 20 μΐ and 30 μΐ, on the operative surface material in ambient air at a temperature of 20 degrees Celsius, at a pressure of one (1) atmosphere, and at a relative humidity of between 30 percent and 50 percent, is less than 40 degrees. In some embodiments, for example, the sliding angle of a water droplet, having a volume of between 20 μΐ and 30 μΐ, on the operative surface material in ambient air at a temperature of 20 degrees Celsius, at a pressure of one (1) atmosphere, and at a relative humidity of between 30 percent and 50 percent, is between 10 degrees and 40 degrees.

[0092] Suitable substrates include, for example, wood, glass, masonry, steel, aluminium, fabrics, ceramic, concrete. The substrate can be natural or can be man-made. The substrate surface may be optionally cleaned, polished, and/or otherwise pretreated or activated in order to improve adhesion to the applied (or deposited) coating composition.

[0093] In some embodiments, for example, the substrate is an article to which another coating composition has been applied or deposited.

[0094] Further embodiments will now be described in further detail with reference to the following non-limitative examples. Example 1 :

[0095] For preparing polymer A2, four equivalents of tri(trimethylsilyloxy)silyl propyl methacrylate (monomer (a)), one equivalent of trimethoxysilyl propyl methacrylate (monomer (b)), and one equivalent of methyl methacrylate (monomer (c)) were mixed in 100ml toluene (functioning as a solvent) under stirring and protection of N₂. 0.02 g Azobisisbutyronitrile was then added to the mixture to initiate the polymerization at 70°C. The reaction was continued over 36 hours. After that, the reaction solution was rotevaporated to remove the toluene. A light yellow color liquid (that included polymer A2) was collected with a yield of 98 percent (i.e. 2 weight percent of polymer A2 was removed with the solvent).

[0096] The molecular weight of each one of the prepared polymers was measured by gel permeation chromatography (GPC). The instrument used was a Viscotek™ TDA-302 size exclusion chromatograph (Viscotek™) equipped with tetra detectors refractive index (RI), UV, viscosity (VISC), and two-angle laser light scattering (7° and 90°, λ=670 nm)]. PS sample (Viscotek™) with a stated peak molecular weight of 99,500 g/mol and a molecular weight distribution ("MWD") of 1.03 was used to calibrate the instrument. Tetrahydrofuran ("THF") was used as the mobile phase at a flow rate of 1.0 mL/min and the column temperature of 30 °C. The samples were dissolved in THF with the sample concentrations of 2.0 mg/mL, depending on molecular weight of the polymer, and 100 μΐ_^ of such solution was injected to start data collection. The data obtained was analyzed using OmniSEC™ software. The produced polymer (i.e. polymer A2) had a weight average molecular weight (Mw) of 91 ,600, a number average molecular weight (Mn) of 29,400, and a polydispersity index (Mw/Mn) of 3.2. [0097] Polymers Al , A3, A4, and A5 were prepared using an identical procedure as that used for preparing polymer A2, with the exception that the ratio of starting monomers (a), (b), and (c) were different in each case. The ratios of starting monomers (a), (b), and (c), used in the preparation of polymers Al to A5, are identified in Table 1.

Table 1. The molar ratio of starting monomers (a), (b) and (c) for preparing polymers Al to A5

[0098] In preparing each one of the polymers A6 to A 10, the ratio of starting monomers (a), (b) and (c) were fixed in the molar ratio of 4: 1 : 1 , and each one of the groups R² and R⁷ is propyl, and the groups R¹, R³, R⁴, R⁵, R⁶, R⁸, R⁹, R¹⁰, R¹⁴, and R¹⁵ (R³, R⁴, and R⁵ are the same, and R⁸, R⁹, and R¹⁰ are the same) were tuned, in the manner set out in Table 2, so as to prepare polymers A6 to A10.

Table 2. R¹, R³, R⁴, R⁵, R⁶, R⁸, R⁹, R¹⁰, R¹⁴, and R¹⁵ groups in polymers A6 to A10

The solubility of each of polymers Al to A10 is listed in Table 3, below.

Table 3. Solubility of polymers Al to A10

Example 2:

[0099] Hydrophobic characteristics of various coating compositions, prepared from the polymeric compounds prepared in Example 1, were evaluated, when the coating compositions were applied to woods and ceramic tiles.

[00100] Solutions were prepared, from each one of the prepared polymers Al to A 10, by dispersing the respective polymer, along with dibutyltin dilaurate (as the catalyst) in ethanol, such that each one of the solutions included 5 weight percent of the combination of the respective polymer and the catalyst, based on the total weight of the solution, with the catalyst present at a concentration of 20ppm. 20 μΐ of each solution was brushed on each substrate (woods and ceramic tiles) over an area of 4 cm². The coated samples were cured at ambient conditions over 6 hours. Tap water droplets were used for measuring the static contact angle (10 μΐ) and sliding angle (30 μΐ). Table 4 illustrates measured water contact angles and sliding angles on coated and uncoated woods. Table 5 illustrates measured water contact angles and sliding angles on coated and uncoated ceramic tiles. NA means that the sliding angle was over 90° on measured surfaces.

*CA means water static contact angle and SA means water sliding angle on the substrates Table 5. Water static contact angles and sliding angles on the surfaces of uncoated and coated ceramic tiles*

*CA means water static contact angle and SA means water sliding angle on the substrates

[00101] In terms of each kind of sample above, two parallel samples were prepared and tested. On each single sample, ten (10) different spots were randomly selected and tested, and average errors were calculated. It was found that, in the testing of sliding angle, there were no trails of water left behind after the water droplet slid off of the coated woods and coated ceramic tiles. Example 3:

[00102] A PTFE emulsion (sigma-adrich) was also applied to coat the woods and ceramic tiles. PTFE emulsion was diluted to 5 weight percent and coated on the substrates, which were cured at 120°C over 2 hours. After that, all the samples were washed by ethanol and water to remove the surfactants that come from the emulsion. When the samples were dried, contact angles were tested. However, no water repellent samples were attained. PTFE treated samples showed hydrophilic property, which should because of the deep absorbed surfactants in the substrates.

Example 4:

[00103] Hydrophobic characteristics of various coating compositions, prepared from the polymeric compounds prepared in Example 1 were evaluated, when the coating compositions were applied to glass slides, and steel and aluminium blocks.

[00104] Solutions were prepared, from each one of the prepared polymers Al to A10, by dispersing the respective polymer, along with dibutyltin dilaurate (as the catalyst) in ethanol, such that each one of the solutions included 3 weight percent of the combination of the respective polymer and the catalyst, based on the total weight of the solution, with the catalyst present at a concentration of 20ppm. Glass slides and steel blocks were dipped in the prepared solutions, and then cured at ambient conditions over 6 hours. Subsequently, tap water droplets were used for measuring the static contact angle (10 μΐ) and sliding angle (30 μΐ) measurements. The surfaces of aluminum and steel blocks were polished by sands paper before coating. Table 6 illustrates the measured water contact angles and sliding angles for the coated and the uncoated surfaces of the substrates. Table 6. Water contact angles and sliding angles on glass, steel and aluminum blocks*

The coatings were cured at ambient conditions over 6 hours. Table 7 illustrates the surface properties of the fabrics before and after the application of the coating.

Table 7. Surface properties of fabrics before and after hydrophobic treatment*

* tap water was used for the static contact angle (10 μΐ water droplet size) and sliding angle (30 μΐ water droplet size) measurements; all the angles were measured after the droplets were put on the surface for 30 sec. NA means that the sliding angle is over 90° on measured surfaces. CA means contact angle. SA means sliding angle.

Example 6:

[00107] A solution was prepared by dispersing polymer A2, along with dibutyltin dilaurate (as the catalyst) in ethanol, such that the solution included 5 weight percent of the combination of the polymer A2 and the catalyst, based on the total weight of the solution, with the catalyst present at a concentration of 20ppm.

[00108] Six (6) spruce samples were provided (each 2x2x 1 cm). Three (3) were coated with the prepared solution, and three (3) remained uncoated. The coated and uncoated spruce pieces were kept in tap water for 24 hours. After that, excess water on samples was wiped off by tissues. All of samples were weighted before and after soaked in water. The water absorption of samples were calculated by the equation,

Water absorption percentage gain = (100 x (W_a - Wo)AV₀) percent, wherein Wa is the weight of sample after absorbing of water and W₀ is the weight of sample before soaked in water. [00109] The non-coated spruce samples had an average 46 percent gain by weight.

The coated one had a 7 percent gain by weight.
