Description
DK 155495 BDK 155495 B
Opfindelsen angår et glasemne til beskyttelse af øjnene og af den art, der omfatter mindst én plade af silikatglas, hvoraf den ene mod brugerens øje vendende side har et lag af svagt tværbundet, transparent polyurethanlag, der har en høj elastisk deformationsevne med forlængelse før brug på over 60% ved et permanent plastisk deformationsforhold på under 2% og et elasticitetsmodul på under 2000 daN/cm . Der kan være tale om briller, masker eller skærme.BACKGROUND OF THE INVENTION The invention relates to a glass blank for the protection of the eyes and of the type comprising at least one sheet of silicate glass, one of which facing the user's eye has a layer of slightly cross-linked, transparent polyurethane layer having a high elastic deformation capability with extension before use on over 60% at a permanent plastic deformation ratio of less than 2% and a modulus of elasticity of less than 2000 daN / cm. These may be glasses, masks or screens.
Ifølge opfindelsen er glasemnet ejendommeligt ved, at der på den bort fra øjnene vendende side af glasemnet også findes et polyurethanlag af i hovedsagen samme beskaffenhed som førstnævnte lag.According to the invention, the glass blank is characterized in that on the side facing the eyes of the glass blank there is also a polyurethane layer of substantially the same nature as the first layer.

ninger hurtigt forsvinder af sig selv, således at det genvinder sit oprindelige udseende.things quickly disappear by themselves, so that it regains its original appearance.
Hovedfordelen ved sådanne glasemner er, at man dels som beskyttelsesglas kan anvende mineralsk glas med de velkendte egenskaber, dels opnår - i det tilfælde, hvor glasset går i stykker -at glasskår tilbageholdes af plastlaget, som desuden ikke er følsomt over for ridsninger, fordi det er selvhelende, hvorfor det bløde lag ikke behøver et yderligere beskyttelseslag. Det bløde, selvhelende lag kan eksempelvis have en tykkelse på 0,1 til 1 mm, fortrinsvis på 0,2 til 0,5 mm.The main advantage of such glassware is that it is possible to use, as protective glass, mineral glass with the well-known properties, and partly obtains - in the case where the glass breaks - that glass shards are retained by the plastic layer, which is also not sensitive to scratches because it is self-healing, which is why the soft layer does not need an additional protective layer. For example, the soft self-healing layer may have a thickness of 0.1 to 1 mm, preferably 0.2 to 0.5 mm.
Med det bløde plastlag på den side af beskyttelsesglasset, clej. vender mod øjnene undgår man, at glasskår i tilfælde af brud løsner sig og skader øjnene eller ansigtet.With the soft plastic layer on the side of the protective glass, clue. facing the eyes, it is avoided that glass shards in case of breakage loosen and damage the eyes or face.
Som følge af polyurethanlagets store deformationsevne kan glasemnet udsættes for kraftige deformationer uden risiko for, at laget rives over. I tilfælde af meget stor strækpåvirkning yder plastlaget en udmærket beskyttelse, idet det folder sig om glasskårenes skarpe kanter, som herved forhindres i at volde skader.Due to the high deformation capability of the polyurethane layer, the glass blank can be subjected to strong deformations without the risk of tearing the layer over. In the case of very high tensile stress, the plastic layer provides excellent protection as it folds over the sharp edges of the glass shards, thereby preventing damage.
Man har konstateret, at det udvendige plastlag på glasemnet, på grund af sine elasticitetsegenskaber praktisk taget er ufølsomt over for de mekaniske påvirkninger, der normalt angriber overfladen af en plade af silikatglas. Man har således konstateret, at det bløde plastlag er i stand til uden skade at tåle langvarig brug ved arbejdet med sandblæsning, medens en plade af silikatglas under lignende forhold hurtigt gøres mat og uigennemsigtig. Masker eller beskyttelsesskærme for personalet, der arbejder med sandblæsning, eller andre beskyttelsesruder til brug under lignende forhold, kan derfor hensigtsmæssigt være forsynet med et sådant plast lag på den side af glaspladen, der vender mod sandstrålen.It has been found that, due to its elasticity properties, the outer plastic layer of the glass blank is virtually insensitive to the mechanical stresses that normally attack the surface of a sheet of silicate glass. Thus, it has been found that the soft plastic layer is able to withstand long-term use without damage during sandblasting work, while a plate of silicate glass under similar conditions quickly becomes dull and opaque. Therefore, masks or protective screens for personnel working with sandblasting, or other protective windows for use in similar conditions, may conveniently be provided with such a plastic layer on the side of the glass plate facing the sandblasting.
Selve silikatpladens udformning kan være forskellig. Den kan f.eks. bestå af én enkelt plade af udglødet glas, dvs. glas uden indre spændinger. I mange tilfælde er det dog hensigtsmæssigt at anvende en silikatglasplade, der er hærdet ad termisk eller kemisk vej. Sådanne plader af hærdet glas har stor styrke over for stødpåvirkninger, hvorfor de anvendes, specielt når der er risiko for mekaniske stød. Glaspladen kan også være en laminatrude bestående af to enkelte silikatglasplader, der er sammenklæbede ved hjælp af et mellemlag af plastmateriale.The design of the silicate sheet itself may be different. It can e.g. consist of a single plate of annealed glass, ie. glass without internal tension. In many cases, however, it is advisable to use a silicate glass plate which is thermally or chemically cured. Such tempered glass sheets have high impact resistance to impact, which is why they are used, especially when there is a risk of mechanical shock. The glass plate may also be a laminate pane consisting of two single silicate glass sheets which are bonded together by an intermediate layer of plastic material.
