Description
Glass for beskyttelse av øynene.Glasses for eye protection.
Den foreliggende oppfinnelse vedrører et glassThe present invention relates to a glass
for å beskytteøynene, som kan anvendes til forskjellige formål, f.eks. briller, maske, skjermer som beskytter øynene o.s.v. to protect the eyes, which can be used for various purposes, e.g. glasses, mask, screens that protect the eyes, etc.
Det nye beskyttelsesglasset ifølge oppfinnelsen består av en plate av silikatglass og erkarakterisert vedat minst en av sidene av denne platen er dekket med et belegg av mykt plastmateriale, som er selvhelende. The new protective glass according to the invention consists of a plate of silicate glass and is characterized in that at least one of the sides of this plate is covered with a coating of soft plastic material, which is self-healing.
Ifølge en foretrukket utførelse består det myke plastbelegget av et alifatisk polyuretan med liten fornetning, som har en elastisitetsmodul på mindre enn 2000 daN/cm 2og en høy bruddforlengelse på mere enn 60 % med en plastisk deformasjonsgrad på mindre enn 2 %. According to a preferred embodiment, the soft plastic coating consists of an aliphatic polyurethane with a small cross-linking, which has a modulus of elasticity of less than 2000 daN/cm 2 and a high elongation at break of more than 60% with a degree of plastic deformation of less than 2%.
Polyuretan har egenskaper som gjør at overfladiske sprekker forsvinner spontant eller etter kort tid, hvoretter materialet får tilbake sitt opprinnelige utseende. Polyurethane has properties that cause superficial cracks to disappear spontaneously or after a short time, after which the material returns to its original appearance.
Belegg som har slike egenskaper er alledede kjent. Ifølge oppfinnelsen ble disse belegg anvendt på glass for briller og beskyttelsesskjermer for øynene av silikatglass. Coatings that have such properties are already known. According to the invention, these coatings were used on glass for spectacles and protective screens for the eyes made of silicate glass.
Man oppnår ved denne anvendelsen en rekke fordeler, for det første kan man som ..beskyttelsesglass anvende minerale glass med de fordeler dette er kjent å medføre, og for det annet vil i tilfelle brudd på mineralglasset glass-splintene bli holdt tilbake av belegget av plastmaterialet og for det tredje er dette materiale på grunn av sine selvhelende egenskaper ufølsomt overfor sprekker, slik at det myke belegget ikke gjør det nødvendig med noe ytterligere beskyttelsesbelegg. Det selvhelende myke belegget kan f.eks. ha en tykkelse på This application achieves a number of advantages, firstly, mineral glass can be used as protective glass with the advantages this is known to entail, and secondly, in the event of a break in the mineral glass, the glass splinters will be held back by the coating of the plastic material and thirdly, due to its self-healing properties, this material is insensitive to cracks, so that the soft coating does not require any additional protective coating. The self-healing soft coating can e.g. have a thickness of
fra 0,1 til 1 mm og fortrinnsvis fra 0,2 til 0,5 mm.from 0.1 to 1 mm and preferably from 0.2 to 0.5 mm.
Belegget av mykt plastmateriale kan påføres f.eks. på den siden av beskyttelsesglasset som vender mot øynene. Man unngår på denne måten at glass-splinter fri-gjøres i tilfelle av knusing, og man unngår å skade øynene og ansiktshuden. The coating of soft plastic material can be applied e.g. on the side of the protective glass facing the eyes. In this way, shards of glass are avoided in the event of breakage, and damage to the eyes and facial skin is avoided.
På grunn av den høye forlengelsesstyrken i belegget av plastmateriale, kan beskyttelsesglasset underkastes meget store deformasjoner, uten at dette belegget går istykker. Snarere tvertimot, virker belegget mer beskyttende i det tilfelle hvor det finner sted en meget stor forlengelse siden det ruller seg rundt de skjærende kanter på glass-splinter og lignende, slik at man unngår skader av slike skarpe kanter. Ved anvendelse på beskyttelsesglass for øynene, oppfyller derfor belegget av mykt plastmateriale på en spesielt fordelaktig måte flere funksjoner,, og resultatet blir et beskyttelsesglass med høy kvalitet. Due to the high elongation strength of the coating of plastic material, the protective glass can be subjected to very large deformations, without this coating breaking. Rather, on the contrary, the coating acts more protectively in the case where a very large extension takes place, since it rolls around the cutting edges of glass splinters and the like, so that damage from such sharp edges is avoided. When applied to protective glasses for the eyes, the coating of soft plastic material therefore fulfills several functions in a particularly advantageous way, and the result is a protective glass of high quality.
Belegget av polyuretanplast kan ikke bare anvendes som et belegg for indre beskyttelse for å unngå kontakt med glass-splintene, men det kan også i enkelte tilfelle med fordel anvendes på den ytre overflate av beskyttelsesglasset. Man har konstatert at dette belegget på grunn av sine elastiske egenskaper er praktisk talt ufølsomt overfor visse mekaniske påvirkninger som vanligvis forandrer over-flaten i silikatglass. Man har således konstatert at dette myke plastbelegget uten å bli forandret kan motstå en lengre anvendelse under sandblåsing, hvorunder de samme anvendelses-betingelser overflaten i et silikatglass ville blitt full-stendig matt og ugjennomsiktig. Masker og beskyttelsesskjermer for personale som arbeider med sandblåsing og også andrei beskyttelsesglass for slike arbeidsbetingelser kan således med fordel være belagt med det nevnte plastbelegg på The coating of polyurethane plastic can not only be used as a coating for internal protection to avoid contact with the glass splinters, but it can also in some cases be advantageously used on the outer surface of the protective glass. It has been established that this coating, due to its elastic properties, is practically insensitive to certain mechanical influences which usually change the surface in silicate glass. It has thus been established that this soft plastic coating, without being changed, can withstand prolonged use during sandblasting, under which the same conditions of use would have made the surface of a silicate glass completely dull and opaque. Masks and protective screens for personnel who work with sandblasting and also other protective glasses for such working conditions can thus advantageously be coated with the aforementioned plastic coating on
den ytre overflate av glasset som vender mot sandblåsings-_ strømmen. Også når dette belegget bare finnes på den ytre siden, vil det i en viss utstrekning kunne holdeintilbake glass-splinter, selv om i prinsippet en total beskyttelse bare til-veiebringes når det også finnes et belegg av mykt plastmateriale på den glass-siden som vender mot øynene. the outer surface of the glass facing the sandblasting flow. Even when this coating is only found on the outer side, it will to a certain extent be able to hold back glass splinters, although in principle total protection is only provided when there is also a coating of soft plastic material on the glass side that faces against the eyes.
Selve platen av silikatglass kan være utførtThe plate itself can be made of silicate glass
på forskjellige måter. Platen kan f.eks. bestå av vanlig monolitisk glass som er utglødet, dvs. som er uten indre spenning. Det er imidlertid anbefalt å anvende en plate av silikatglass som er underkastet en termisk eller kjemisk herdning. Disse herdede glassplater er særlig motstands-, dyktige mot sjokk, og bør spesielt anvendes i tilfeller hvor man frykter mekaniske påkjenningér.1 en annen utførelse kan silikatglasset likeledes være et flerlagsglass, dvs. sammen-satt av to eller flere glasplater som er sammenlimt ved mellomliggende belegg av termoplastisk materiale. in different ways. The plate can e.g. consist of ordinary monolithic glass that is annealed, i.e. without internal tension. However, it is recommended to use a sheet of silicate glass which has been subjected to a thermal or chemical hardening. These toughened glass sheets are particularly resistant, able to withstand shocks, and should especially be used in cases where mechanical stress is feared. In another embodiment, the silicate glass can also be a multi-layered glass, i.e. composed of two or more glass sheets that are glued together at intermediate points. coating of thermoplastic material.
