Description

Fremgangsmåte for fremstilling av et laminert materiale av polyuretanplast eller polyuretanskumplast og et annet materiale. Method for producing a laminated material of polyurethane plastic or polyurethane foam plastic and another material.

Oppfinnelsen angår en fremgangsmåte for fremstilling av et laminert materiale av en bane av polyuretanplast eller The invention relates to a method for producing a laminated material from a web of polyurethane plastic or

polyuretanskumplast og et baneformet materiale, eksempelvis et vevet stoff eller en polyurethane foam plastic and a web-shaped material, for example a woven fabric or a

plastfolie uten anvendelse av klebemidler. plastic film without the use of adhesives.

Ved fremstilling av slike laminerte materialer er det av forskjellige grunner uøn-sket å anvende klebemidler, f. eks. fordi In the production of such laminated materials, it is for various reasons undesirable to use adhesives, e.g. because

prisen på det laminerte materialet derved the price of the laminated material thereby

forhøyes, videre fordi mange klebemidler is increased, further because many adhesives

angripes av mugg og insekter, videre fordi attacked by mold and insects, further because

det laminerte materialet oppstives som the laminated material is braced as

følge av klebemidlet, dvs. at bøyeligheten result of the adhesive, i.e. that the flexibility

av begge materialene i det laminerte materialet på grunn av klebemidlet går tapt, of both materials in the laminated material due to the adhesive is lost,

eller fordi klebemidlet angripes av vaske-midlene eller de kjemiske rensemidler, som or because the adhesive is attacked by the detergents or the chemical cleaning agents, which

anvendes for å rengjøre det laminerte materialet. used to clean the laminated material.

Det er kjent å foreta en hurtig oppvarmning av polyuretankunststoff til smel-tetemperaturen og deretter forbinde dette It is known to rapidly heat polyurethane plastic to the melting temperature and then connect this

med et annet materiale til et laminert pro-dukt uten å anvende Mebemiddel. Den with another material into a laminated product without using Mebemiddel. It

sammenklebing som oppnås ved en slik bonding which is achieved by such

fremgangsmåte resulterer i et laminert materiale som for mange formål' ikke vil være method results in a laminated material which for many purposes will not be

sterkt nok, fordi bare kantene av porene i strong enough, because only the edges of the pores i

polyuretankunststoffet forbinder seg med the polyurethane plastic connects with

det andre materialet. the other material.

Fremgangsmåten ifølge oppfinnelsen The method according to the invention

går ut på fremstilling av et laminert materiale av en bane av polyurentanskum-plast og annet materiale som også foreligger i baneform, særlig tekstilmateriale, involves the production of a laminated material from a web of polyurethane foam plastic and other material that is also available in web form, particularly textile material,

hvor polyurentanplastens overflate ved oppvarmning gjøres klebrig, f. eks. ved at den smeltes, hvoretter det andre materiale presses mot den klebrige, overflaten, og fremgangsmåten karakteriseres ved at where the surface of the polyurethane plastic is made sticky by heating, e.g. in that it is melted, after which the other material is pressed against the sticky surface, and the method is characterized by

overflaten av polyurentanplasfcen opphetes hurtig ved hjelp av gassflammer til en temperatur som ligger vesentlig over polyuretanplastens smeltetemperatur, slik at overflatelaget av polyuretanplastbanen i det the surface of the polyurethane plastic is heated quickly with the help of gas flames to a temperature that is significantly above the polyurethane plastic's melting temperature, so that the surface layer of the polyurethane plastic web in the

minste delvis avbrennes, før det andre materiale forbindes med polyuretanplastens overflate. the smallest is partially burned off, before the other material is connected to the surface of the polyurethane plastic.

Patenthaverne har videre funnet at be-stemte ipolyuretanplaststoffer og polyure-tanskumplaststoffer, som ved oppvarmning tal en. temperatur, som ligger, langt over polyurentanets smeltepunkt, slik at en del av materialoverflaten avbrennes, etter av-kjøling til en temperatur, som ligger vesentlig under smeltepunktet for polyuretan, forblir myke og ikilebrige, d.v.s. at det foregår en form for underkjøling hvorved det også kan klebes til ømfintlige, vevete materialer, f. eks. av polyamid, ull eller andre materialer, hvis spaltningstempera-tur ligger under smeltepunktet for polyuretan. Derved oppnås det en sterk binding mellom lagene og det fremstilte laminerte 2nateriale er mykt og bøyelig og blir hver-ken angrepet av sopp eller insekter eller vaskemidler eller kjemikalier som vanligvis anvendes for rengjøring. The patent holders have further found that certain polyurethane plastics and polyurethane foam plastics, which when heated count one. temperature, which is far above the polyurethane's melting point, so that part of the material surface is burned off, after cooling to a temperature which is significantly below the polyurethane's melting point, remain soft and non-brittle, i.e. that a form of subcooling takes place whereby it can also stick to delicate, woven materials, e.g. of polyamide, wool or other materials, whose decomposition temperature is below the melting point of polyurethane. Thereby a strong bond is achieved between the layers and the manufactured laminated material is soft and pliable and is neither attacked by fungi or insects nor detergents or chemicals that are usually used for cleaning.

Fremgangsmåten ifølge oppfinnelsen kan anvendes ved alle de polyuretanstoffer som ved den beskrevne varmebehandling gdr spaltningsprodukter, som stivner ved. en temperatur under polyuretanets smelte- The method according to the invention can be used with all the polyurethane substances which, in the described heat treatment, generate cleavage products, which solidify. a temperature below the polyurethane's melting
