Problems solved by technology

Incorporation of pigments to render the coating opaque, especially enough so that the resulting coating is difficult to cure and thus less durable
No floor coverings comprising a pigmented high-performance topcoat, or a pigmented high-performance anti-wear layer coated with a high-performance topcoat, are hitherto known

Embodiment 1

[0051]A hydroxyl terminated polyester PE1 was prepared according to Example 1 of UPS No. 5,663,003, incorporated herein by reference. The polyester is prepared based on the following composition:

[0052] 1,6 hexanediol 992.7g

[0053] Glycerin 133.5g

[0054] Phthalic anhydride 1071 g

[0055] Dibutyltin dilaurate 0.5 g

[0056] The reaction mixture was cooled to obtain the final product with an acid number of 2.4 and a hydroxyl number of 179.

[0057] A coating composition was prepared as described in UPS No. 5,719,227, incorporated herein by reference. The following composition was charged to a 2 L flask equipped with a heating mantle, stirrer, and purged with dry air at a rate of 0.25 scf / hr:

[0058] Tone M-100 Hydroxyacrylate by Union Carbide 126g

[0059] Monomer mixture (27.5 wt.% of Sartomer SR499, 27.5 wt.% of 125 grams of Sartomer SR502, 45 wt.% of Sartomer SR351)

[0060] PE1 35g

[0061] The mixture was heated to 100°F and 87 grams of Desmo...

Embodiment 2

[0063] Top coat #1 is TiO 2 Pigment (R-HD6X, supplied by Huntsman) formulated with additional UV photoinitiator. The composition was preheated and applied to a backside printed rigid vinyl film to a thickness of 2 mils. The coated film was conveyed through a 12.75 inch heated drum maintained at about 150°F. With a wrap angle of about 90 degrees, the film is exposed to ultraviolet radiation using a conventional medium pressure mercury vapor lamp or a doped (V bulb) lamp whose spectral output covers the entire UV 200-450nm range. The coated and pigmented abrasion resistant film is then laminated to a tile substrate. The coating had good adhesion and acceptable floor abrasion resistance as judged by the Modified Tabor Abrasion Test Method. Table 1 shows the TiO 2 Various formulations of pigmented paints. All amounts are parts by weight unless otherwise indicated.

[0064] The formula of the colored paint of table 1 embodiment 1

Embodiment 3

[0066] With a kind of pearlescent pigment (Golden Bronze 2.24 μ m, provided by Mearl Corp), prepare top coat coating composition, be coated on the rigid vinyl film, carry out by the method for embodiment 2 with medium pressure mercury vapor lamp UV curing. The cured topcoat was used in flooring applications with acceptable performance.

Abstract

A method and composition for providing a colored high performance wear surface for floor coverings is disclosed. Specifically, the floor covering includes a substrate and a high performance layer comprising a radiation cured pigmented composition. The exposed surface of the floor covering has a stain resistance of less than about 150 Delta E units. A pigmented high performance wear layer can be added in register with a printed design on the substrate or in register with an embossed texture of the substrate. Additionally, a high performance topcoat wear layer may be added. The pigmented high performance layer may include a nacreous pigment.

Description

field of invention [0001] The present invention relates to a floor covering having a radiation curable high performance pigmented topcoat and a radiation curable high performance pigmented abrasion resistant layer adjacent to the radiation curable high performance topcoat. Background of the invention [0002] Resilient floor coverings can be formed as sheets or as individual floor tiles. Typically, in the manufacture of resilient floor coverings, the wear resistant layer is combined with a substrate and resin to form a resilient sheet or floor tile. The substrate typically comprises laminated felted or woven fiberboard, or entangled filaments or fibers. Generally, a substrate is applied with a substantially uniform coating of a liquid or semi-liquid resinous composition comprising a synthetic polymeric material, usually ungelled polyvinyl chloride Plastisols and blowing agents. This liquid or semi-liquid plastisol vinyl composition is then hardened or gelled at elevated t...
