Problems solved by technology

A further disadvantage of UV-curing coatings, e.g. in the case of PUR coatings, is that crosslinking is limited, which can in particular limit the gas barrier function of the coating

Embodiment 1

[0126] Example 1: Linoleum Base

[0127] First, all the components of the linoleum composition listed in Table 1 below were mixed in a suitable mixing apparatus to form a base mass (mixed mass) as homogeneous as possible. The mixed mass thus obtained is processed into skins and conveyed to a scraper or granulator, after which the granules of the mixed mass thus obtained are conveyed to a calender and pressed, for example as a substrate, under pressure and at a temperature of typically 10°C to 150°C The material is jute. The panels obtained are then stored in an aging cabinet at about 80° C. for 2 to 3 weeks.

[0128] The formulations are listed as an example in Table 1, where the values ​​indicated are in % by weight relative to the amount of the total mixture (linoleum layer). The individual components of the formulations specified in Table 1 were chosen such that for each particular formulation of the linoleum layer a value of 100% by weight was produced.

[0129] Table ...

Embodiment 2

[0131] Example 2: Coated Linoleum Base

[0132] Each roll coat applied a coat, the composition and amount of which is shown in Table 2, to the base layer. As evident from Table 3, the coating was cured initially by irradiation with an excimer lamp (Excirat 172) at a wavelength of 172 nm at a line speed of 10 m / min under a nitrogen atmosphere (oxygen content below 150 ppm). In a second irradiation step with a mercury lamp at the same line speed (Printworld PUVD 270-2, without IR lamp, UV1 and UV2, 160 W / cm power), the curing of the coating is carried out under normal atmosphere.

Embodiment 3

[0145] Example 3: Emissions measurement

[0146] The emissions from these panels obtained were measured using the FLEC test.

[0147] FLEC measurement unit used: Chematec (SCP Seitz Chromatographic Products GmH); measurements were performed after 28 days.

[0148] Table 4

[0149]

[0150] The results of the FLEC tests are presented in Table 5, where it is evident that the uncoated linoleum layer has a TVOC value of up to 170 μg / m 2 h. This value is slightly higher than for PUR-coated linoleum layers.

[0151] Examples 2 and 3, which did not contain a photoinitiator in the coating, had lower TVOC values ​​than the uncoated linoleum layer. However, although they do not contain a photoinitiator, Examples 2 and 3 have significantly higher TVOC values ​​than Examples 4 to 7 according to the invention.

Abstract

Described herein are low-emission sheet materials, comprising at least one base layer and a (meth) acrylate-based coating arranged thereon, wherein the sheet material has a TVOC (total volatile organic compounds) value of ≤ 50μg / m2.h, measured according to ISO 16000-10 by means of a field and laboratory emission cell (FLEC). Also described herein, are methods for making and using wear layers and sheet materials comprising same, obtained by irradiation at a wavelength from 10nm to 200 nm or by irradiation wing a source of high-energy photons in combination with a UV radiator.
