Abstract

By means of this invention, glass beads are coated with natural and organically modified montmorillonite to be competed with commercial products, applied easily, compatible with environmentally friendly water-based road marking paints, have high wear resistance and retoreflectivity. Coated glass beads are spread on the vvater based paint that is applied on 10 x 50 cm briquettes, soon after the paint applying process. Ratio of glass beads to paint is 33 % by vveight. After paint dries, in order to simulate the way, a vvheel with 6 bars pressure shutties on the paint. At the end of this process, night visibilities are measured. After 10.000 cycles of shuttling, night visibility of paint inciuding vvater based montmorillonite coated glass bead is higher than the paints inciuding commercial silane coated, uncoated and modified montmorillonite coated glass beads. Modified montmorillonite coated glass beads provide similar night visibility when compared to commercial silane based glass bead and higher night visibility than uncoated glass bead.

Description

TARIFNAMEW Bulusun Ilqili Oldugu Teknik Saha Bulus, uygulamasi özellikle çevre dostu su bazli yol çizgi boyalarinda gerçeklestirilmis olup, yoI çizgi boyalarinda gece görünürlülügünü arttiran cam kürecik yüzeylerinin daldirma yöntemiyle nanoboyutlu inorganik esasli dogal bir kil (montmorillonit) ve/veya modifiye kil ile kaplanmasi, kaplama sonucunda da cam küre yüzey özelliklerinin gelistirilerek, ticari benzerlerine göre yüksek retroreflektif özellige sahip, asinma direnci daha yüksek dolayisiyla uzun ömürlü gece görünürlügüne sahip boya uygulamasina olanak saglayan, ucuz cam küreciklerin elde edilmesi ile ilgilidir. DESCRIPTION Technical Field to which the Invention Relates The application of the invention is especially in environmentally friendly water-based road marking paints. glass that increases night visibility in road marking paints. A nano-sized inorganic-based natural clay with the dipping method of the spherical surfaces. (montmorillonite) and/or modified clay, resulting in glass By improving the spherical surface properties, it is highly retroreflective compared to its commercial counterparts. feature, with higher abrasion resistance, therefore, long-lasting night Inexpensive glass beads that allow the application of paint with high visibility. it's about getting it.

Teknigin Bilinen Durumu Cam küreler boya uygulamasinin hemen ardindan farkli gradasyonda olacak sekilde boya yüzeyine yayilmakta olup en büyük boyutlular en üstte, düsük boyutlular alta yerlesecek sekilde uygulama gerçeklestirilmektedir. Bu uygulamanin uygun olmasi gece görünürlügü açisindan çok önemli olan retroreflektif özellikte yol çizgi boyalari elde edilmesinde kritik bir öneme sahiptir [1,2,3]. Cam küre parçaciklari serbest akis göstermez ise istenilen düzgün dagilim saglanamamaktadir. Tane boyutu küçük kürelere cam yüzeyinde bulunan hidrofilik -OH grubu nedeniyle nem etki etmekte ve topaklanma problemi ortaya çikabilmektedir. Topaklanma, cam küre yüzeyinin hidrofobik kaplanmasi ile önlenebilmektedir. Ancak, cam küre yüzeyindeki hidrofobik kaplama malzemesi ile boya arasinda iyi bir adhezyon saglanmamasi durumunda trafik altinda cam kürecikler boya yüzeyinden kolayca kopabilmektedir. Dolayisi ile retroreflektif kaybina neden olan uygulamalar söz konusu olabilmektedir. Bunu önlemek için de arada ayrica baglayici ajan kullanimi gerçeklestirilmektedir. Ancak bu durumda da boya cam küre yüzeyini çok kaplamakta ve sonuçta retroreflektivite düsmektedir. Ayrica, baglayici ajanlar hidrofobik olmadigi için topaklanma probleminin artisina da neden olabilmektedir [2]. State of the Art Glass spheres should be in different gradation immediately after paint application. spreads over the paint surface and the largest sizes are at the top, the lower ones are at the bottom. The application is carried out in such a way that it is settled. The suitability of this application Road marking paints with retroreflective properties, which are very important in terms of night visibility. It has a critical importance in obtaining it [1,2,3]. Glass sphere particles free flowing If it does not show the desired smooth distribution cannot be achieved. Small grain size Spheres are affected by moisture due to the hydrophilic -OH group on the glass surface and agglomeration problem may occur. Clumping of the glass ball surface can be prevented by its hydrophobic coating. However, the hydrophobic If good adhesion is not provided between the coating material and the paint. Glass beads can easily break from the paint surface under traffic. Due to There may be applications that cause retroreflective loss. this much In order to prevent this, a binding agent is also used in between. However In this case, too, the paint covers the surface of the glass ball too much, resulting in retroreflectivity. is falling. In addition, because the binding agents are not hydrophobic, agglomeration It can also cause an increase in the problem [2].

Baslangiçta büyük boyutlu cam kürelerin yüzeyde olmasina bagli olarak yüksek olan retroreflektivite zamanla araçlarin üzerinden geçmesi yani mekanik etkiler ve boyanin asinmasiyla birlikte retroreflektivite degeri paralel olarak azalis göstermektedir. Cam küre asinmasi sonucu olusan bosluklar tozla kaplanip yüzey grilesmekte ve hem gece hem de gündüz retroreflektivitesi azalmaktadir. Initially high due to the large sized glass spheres on the surface. retroreflectivity, that is, passing over vehicles over time, that is, mechanical effects and paint With wear, the retroreflectivity value decreases in parallel. Pine The cavities formed as a result of the wear of the sphere are covered with dust and the surface becomes gray and both both night and day retroreflectivity decreases.

Yüzey modifikasyonu yapilmamis olan cam kürelerin boya ile adezyonu düsük olacagindan, boya içerisindeki cam kürelerin kopmasi daha kolaydir. Glass spheres without surface modification have low adhesion with paint. It will be easier for the glass spheres in the paint to break off.

Literatüidgmgm üstesinden gelebilmek için cam kürecikler polimerik yama organik esasli çesitli malzemelerle kaplanmistir. kürenin kaplanmasinda kullanilmistir [4]. US3222204 nolu patentde florokarbonlar kullanilmistir. Her iki uygulama da pahalidir ve olusan ürünlerin performans testleri sonrasi yipranmasi fazladir. Yani yol çizgi boyasi üzerinden tasit geçtikçe cam kürelerin boya yüzeyinden kopmasi fazladir [5]. elde edilen poliüretan esasli polimerik malzemelerle cam kürecikler kaplanmistir. Bu yöntem de pratik olmayan pahali bir yöntemdir ve istenilen performans sonuçlara ulasilamamaktadir [1]. Glass beads polymeric patch to overcome literature idgmgm It is coated with various organic-based materials. It was used in the coating of the sphere [4]. Fluorocarbons in patent US3222204 used. Both applications are expensive and the performance tests of the resulting products wear is excessive. That is, as the vehicle passes over the road marking paint, the glass the rupture of the spheres from the paint surface is high [5]. Glass beads were coated with the obtained polyurethane-based polymeric materials. This method is also an impractical and expensive method and the desired performance results in results. cannot be reached [1].

Literatürde çogunlukla hidrofobik yapisi nedeniyle silan bilesikleri kaplama malzemesi olarak kullanilmistir. Ticari uygulamalarda da silan bilesikleri ile kapli cam bu uygulamalar kapsiz cam kürelere ve diger uygulamalara kiyasla daha pratik olmakla birlikte bu çalismadan da görülebilecegi gibi daha çevreci, daha ucuz ve dogal malzemeler bulunabilir [6,7,8,9]. kullanilmistir [3]. peroksit ile karistirilmistir. Bu çalisma daha karmasik, özel bir dikkat gerektirdigi için pahali bir kaplama yöntemidir [10,11] Ayrica benzoil peroksit uçucu ve alev alici bir malzeme oldugundan süreç içerisinde kaplama etkisi azalacak alev alma tehlikesi de söz konusu olabilecektir. In the literature, silane compounds are mostly used for coating due to their hydrophobic nature. was used as the material. Glass coated with silane compounds also in commercial applications these applications are more practical compared to uncapped glass balls and other applications However, as can be seen from this study, it is more environmentally friendly, cheaper and natural materials can be found [6,7,8,9]. has been used [3]. mixed with peroxide. This study is more complex, as it requires special attention. It is an expensive coating method [10,11] In addition, benzoyl peroxide is a volatile and flammable Since it is a material, the coating effect will decrease in the process and the danger of flaming is also present. may occur.

WOO1/42349 patentinde digerlerinden farkli olarak cam küreler poli vinil asetat ile kaplanmistir. Kaplanan cam küreler yol çizgi boyasina serpildikten sonra bir yil içerisindeki gece görünürlülügü degerleri ölçülmüstür. Sonuçlara göre polivinil asetat kaplamali cam kürelerin boyaya tutunmasinin kaplamasiz cam kürelere göre daha iyi oldugu görülmektedir. Ancak silan kapli ticari ürünler ile herhangi bir karsilastirma yapilmamistir. Ayrica polivinil asetat, silan bilesiklerine göre daha pahali olabilmektedir [10]. In the WOO1/42349 patent, unlike the others, the glass spheres are made of poly vinyl acetate. is covered. One year after the coated glass balls are sprinkled on the road marking paint Night visibility values in the interior were measured. According to the results polyvinyl acetate Coated glass balls have better adhesion to paint than uncoated glass balls. appears to be. However, any comparison with silane-coated commercial products not done. In addition, polyvinyl acetate is more expensive than silane compounds. can be [10].

Söz konusu bulus ile ticari ürünler ile rekabet edebilecek, inorganik esasli, ucuz, uygulamasi kolay ve çevreye zarari olmayan ve özellikle çevre dostu su bazli yol çizgi boyasi ile oldukça uyumlu asinma direnci yüksek &yüksek retroreflektif . özellige &p cam kürecikler elde edilebilmektedir. With the said invention, inorganic based, cheap, easy to apply and environmentally friendly, especially environmentally friendly water-based road Highly abrasion resistant & highly retroreflective, highly compatible with line paint. especially &p glass beads can be obtained.

Bulusun Çözümünü Amaçladigi Teknik Problem Yollarda gündüzleri rahatlikla görülebilen yol çizgileri, gece karanlikta görünür olmalarini yüzeylerinde bulunan cam kürelerine borçludur. Cam küreler küresel seklinin ve cam yapisinin etkisiyle, gece araçlardan yol çizgilerine gelen far isiklarini geri yansitarak sürücüye yatay isaretleri görünür kilmaktadir. Bu da sürücünün yol çizgileri sayesinde yönlendirilmesine ve daha dikkatli, trafik kurallarina uygun bir yolculuk yapmasina yardimci olmaktadir. Cam küreler; yagmurlu havada bile far isigini geri yansitabildikleri için, geceleri trafik güvenligini saglamak açisindan önemlidir. Bu sekilde gelen isigin isik kaynagina geri yansitilmasina boya içindeki yüzdesi, hacimce boya yüzeyinde kalacak kismi, retroreflektivite en yüksek düzeyde olacak sekilde ayarlanmaktadir. The Technical Problem That The Invention Aims To Solve Road lines, which can be easily seen on the roads during the day, are visible in the dark at night. They owe their existence to the glass spheres on their surfaces. glass spheres spherical With the effect of its shape and glass structure, the headlights coming from the vehicles to the road lines at night reflects back, making horizontal markings visible to the driver. This is the driver's way lines and a more careful, traffic-compliant It helps him travel. glass spheres; even in the rain Since they can reflect the light back, they are used to ensure traffic safety at night. is important. In this way, the incoming light is reflected back to the light source. the percentage in the paint, the part that will remain on the paint surface by volume, the retroreflectivity is set at a high level.

Yol çizgi boyalarinin üzerinden araçlar geçtikçe boyaya tutunmus olan farkli gradasyondaki cam kürelerin yüzeyde bulunan büyük tane boyutlulari araçlarin yapmis oldugu sürtünme etkisiyle yüzeyden ayrilmakta ve küçük tane boyutlular boyanin da zamanla asinmasina bagli olarak yüzeye dogru çikmaktadirlar. Sonuçta da, gece görünürlülügü zaman içinde azalmaktadir. Gece görünürlülügünün uzun süreli olmasi için cam küre ile boya arasinda siki bir bag olmalidir. Bunu saglayabilmek için de cam küreler, bu bagi saglayabilecek farkli malzemelerle kaplanmaktadirlar [1,2,3]. Literatürde bunu saglayabilmek için genellikle organik esasli polimerik yapiya sahip malzemeler tercih edilmistir. Bu tür malzemelerin yapilari boya malzemesi içinde bulunan baglayici ile uygun kimyasal yapida olmalidir ki uygulama sirasinda yol çizgi boyasi üzerine atilan cam küreciklerin bir kismi yukarida kalirken bir kismi da boyaya batmadan durabilecek sekilde yapisma islemi gerçeklestirilmelidir. Yani kaplama malzemesinin kimyasal yapisi boya içinde bulunan baglayiciya yapisacak sekilde seçilmelidir. Bu tür malzemelerde ayrica zamanla günesin etkisiyle sararma problemleri olabildigi gibi hava sicakliginin artmasina bagli olarak cam kürecik üzerinde bulunan kaplamalarda organik esasli bazi bilesenlerin difüzyonu gibi problemler de yasanabilmektedir. As vehicles pass over the road marking paints, different paints are attached to the paint. The large grain sizes of the glass spheres in the gradation It is separated from the surface by the effect of friction and small grain sizes they rise towards the surface depending on the wear of the paint over time. After all Also, visibility at night decreases over time. Long night visibility For it to last, there must be a tight bond between the glass ball and the paint. this much In order to provide this bond, glass spheres are made with different materials that can provide this bond. they are covered [1,2,3]. In order to provide this in the literature, organic Materials with based polymeric structure are preferred. Such materials Their structure should be in a chemical structure suitable for the binder in the paint material. Some of the glass beads thrown on the road marking paint during two applications The process of sticking in such a way that a part of it can stand without sinking into the paint while remaining above should be carried out. In other words, the chemical structure of the coating material is in the paint. It should be selected to stick to the connector found. In such materials, There may be yellowing problems with the effect of the sun over time, as well as the air temperature. organic-based coatings on the glass bead depending on the increase in Problems such as diffusion of some components can also be experienced.

Bu bulusta cam küreler, inorganik esasli, nanoboyutlu dogal sodyum montmorillonit ve kuaterner amonyum tuzlari ile modifiye edilmis montmorillonit örnekleriyle kaplanmistir. Daha sonra, kaplanmamis veya ticari olarak su bazli yol çizgi boya uygulamalarinda önemli bir yere sahip silan esasli polimerik malzemelerle kapli cam kürelerle performans açisindan kiyaslanmistir. Performans testleri sonrasinda daha daha uzun ömürlü bir uygulama olanagi saglanmistir. Ayrica ilgili kaplama malzemesinin inorganik esasli dogal bir ürün olmasina bagli olarak zamanla yasanabilecek difüzyon problemleri engellenirken daha ucuz maliyetler söz konusudur. Kaplamada kullanilan malzemenin simdiye kadar bu amaçla ilk kez bu çalisma ile kullanilmis olmasi, dogal kaynaklarin katma degeri yüksek ürünlere dönüstürülmesi açisindan da ayrica bir öneme sahiptir. Üstün geri yansitma özelliginin ve yüksek asinma direncinin yanisira yukarida belirtilen tüm özellikleri nedeniyle bu bulus diger patentlerden farklilik arz etmektedir. In this invention, glass spheres are inorganic based, nanosized natural sodium montmorillonite. and montmorillonite samples modified with quaternary ammonium salts. is covered. Next, uncoated or commercially water-based road marking paint Glass coated with silane-based polymeric materials, which have an important place in Compared to spheres in terms of performance. After performance tests a longer lasting application opportunity is provided. Related coating over time, depending on the fact that the material is an inorganic based natural product. While preventing diffusion problems that may occur, cheaper costs are promised. subject. This is the first time that the material used in the coating has been used for this purpose until now. The fact that it has been used with work, natural resources to products with high added value. It is also important in terms of conversion. Superior reflectivity In addition to its feature and high wear resistance, all the above-mentioned features Therefore, this invention differs from other patents.
