Description
i 151188in 151188
Den foreliggende opfindelse angår en fremgangsmåde til co-ekstrudering, ved hvilken et grundprofil af et termoplastisk formstof/ navnlig PVC eller ABS, belægges med et lag på i det mindste en del af grundprofilets udvendige side, i en tykkelse 5 på mellem 0,1 og 1,0 mm og bestående af polymethylmethacrylat eller en co-pqlymer deraf til fremstilling af profiler til dør- eller vinduesrammer.The present invention relates to a method of co-extrusion in which a base profile of a thermoplastic resin / especially PVC or ABS is coated with a layer of at least a portion of the outer side of the basic profile, at a thickness of between 0.1 and 1.0 mm and consisting of polymethyl methacrylate or a copolymer thereof for the production of profiles for door or window frames.
Fremgangsmåden som sådan er kendt fra USA-patent nt. 3.447.997.The method as such is known from U.S. Patent 3447997.
Det er kendt i byggeindustrien, at man ofte til udvendigt 10 brug anvender profiler, f.eks. som vinduesrammer eller dørkarme, af termoplastiske formstoffer, som f.eks. hård PVC.It is known in the construction industry that profiles for exterior use are often used, e.g. such as window frames or door frames, of thermoplastic moldings, such as e.g. hard PVC.
Sådanne profiler angribes ofte af vejrliget, idet især stærk bestråling af sollyset på den ene side og temperatursvingninger på den anden side i betydelig grad belaster de anvend-15 te termoplastiske formstoffer lige til grænsen af deres funktionsevne. I bygningsindustrien spiller således lysbestan-digheden af de anvendte termoplastiske formstoffer af udseendemæssige grunde en væsentlig rolle i det lange løb på samme måde som vejrbestandigheden af formstofferne, dvs. pro-20 filerne og deres forhold overf or belastningen ved temperaturforskelle.Such profiles are often attacked by the weather, with particularly strong irradiation of the sunlight on the one hand and temperature fluctuations on the other, significantly stressing the thermoplastic resins used, just to the limit of their functionality. Thus, in the building industry, the light resistance of the thermoplastic resins used for appearance reasons plays a significant role in the long run in the same way as the weather resistance of the resins, ie. the profiles and their conditions transfer the load by temperature differences.
Fra USA-patent nr. 3.447.997 kendes en fremgangsmåde til fremstilling af et vejrbestandigt formstoflaminat, ved hvilken der ved hjælp af trykruller påføres et polymethylmethacrylat-indeholdende.0,125 til 0,5 mm tykt dæklag i plader eller ba-25 ner ved laminerede, ekstruderede foliebaner. Denne kendte fremgangsmåde er imidlertid ikke egnet til fremstilling af profiler til dør- eller vinduesrammer, idet sådanne profiler har kamme og fremspring, hvorved profilet deformeres, dersom der udøves et lokalt tryk for lagpåføringen ved sam-30 tidig opvarmning med henblik på opnåelse af en stabil hæfteforbindelse.U.S. Patent No. 3,447,997 discloses a method of producing a weather-resistant plastic laminate in which a polymethylmethacrylate containing.0,125 to 0.5 mm thick cover sheet or laminated sheet is applied by pressure rollers. extruded film webs. However, this known method is not suitable for producing profiles for door or window frames, such profiles having ridges and projections, whereby the profile is deformed if a local pressure is applied to the layer application upon simultaneous heating to obtain a stable booklet connection.
Fra USA-patentskrift nr. 3.767.523 kendes endvidere en fremgangsmåde til co-ekstrudering af flerlags-folier, hvor forskellige formstoffer afgives samtidigt gennem en fælles dyse.U.S. Patent No. 3,767,523 also discloses a method for co-extrusion of multilayer films, wherein various resins are released simultaneously through a common nozzle.

Formålet med opfindelsen er at fremstille profiler på grundlag af termoplastisk formstof med forbedret lys- og vejrbestandighed. Dette formål opnås ifølge opfindelsen ved an-5 vendelse af den indledningsvis nævnte fremgangsmåde.The object of the invention is to produce profiles based on thermoplastic resin with improved light and weather resistance. This object is achieved according to the invention by using the method mentioned initially.
Til co-ekstrusion egner sig især polymethylmethacrylater eller deres co-polymere eller blandinger af disse med en molekylvægt på ca. 120.000 til 180.000.Particularly suitable for co-extrusion are polymethyl methacrylates or their copolymers or mixtures thereof having a molecular weight of approx. 120,000 to 180,000.
Ekstruderede profiler fremstillet ved anvendelse af denne 10 fremgangsmåde er ejendommelige ved, at de i det mindste på en del af omkredsen er forbundet f ast med et lag af pdLymethyl-methacrylat eller en af dettes co-polymere, idet dette lag fortrinsvis har en tykkelse på 0,1 mm til 1 mm. Med PMMA-laget opnår man en høj brillans af profilet, og ved ind-15 farvning af laget opnår man en høj lysstyrke og renhed af farverne. Alt efter de anvendte tilsætningsmidler, f.eks. et UV-absorberende stof, til PMMA eller dettes co-polymere kan laget gøres stærkt absorberende overfor UV-området i spektret. Med profiler med et sådant påført lag opnår man 20 de netop i bygningsindustrien ønskede i mange år farve-bestandige bygningsdele, der yderligere er væsentligt mere modstandsdygtige overfor vejrliget.Extruded profiles prepared using this method are characterized in that they are at least part of the circumference connected to a layer of pdLymethyl methacrylate or one of its copolymers, this layer preferably having a thickness of 0.1 mm to 1 mm. With the PMMA layer, you achieve a high brilliance of the profile, and by in-coloring the layer you achieve a high brightness and purity of the colors. Depending on the additives used, e.g. a UV absorbent, to the PMMA or its copolymers, the layer can be made highly absorbent against the UV region of the spectrum. With profiles with such an applied layer, 20 those precisely desired in the building industry for many years achieve color-resistant building parts, which are furthermore significantly more resistant to the weather.
Til pigmentering af ΡΜΜΆ-laget kan foruden de almindeligt kendte farvestoffer ligeledes med fordel anvendes pigmenter 25 med en høj absorptionsgrad af synligt lys samtidig med en stærk tilbagekastning i det infrarøde område. Med sådanne pigmenter opnås, at opvarmning ved bestråling fra solen formindskes, således at vejrbestandigheden af bygningsdelene forøges.For the pigmentation of the ΡΜΜΆ layer, in addition to the commonly known dyes, pigments 25 with a high degree of absorption of visible light can also be used at the same time as a strong reflection in the infrared region. With such pigments it is obtained that heating by radiation from the sun is reduced, so that the weather resistance of the building parts is increased.
30 i øvrigt udviser belægningen af termoplastiske formstof-profiler, med f.eks. PMMA, ligeledes gunstige egenskaber30 moreover, the coating exhibits thermoplastic plastic profiles, e.g. PMMA, also beneficial properties
