Description
Vynález sa týká sposobu výroby 1'ahčeného plošného útvaru s vlasovým, povrchom na báze hlór obsahujúcičh vinylových homoplymérov a/alebo kopolymérov želatináciou, nadúvaním a fixáciou vlasovej vrstvy v jednom technologickom procese.The present invention relates to a process for the production of a lightweight, hair-based, hair-based surface comprising vinyl homopolymers and / or copolymers by gelation, puffing and fixation of the pile layer in one process.
Známe je, že vytváranie vlasového povrchu na íahčených polymérnych materiáloch vločkováním sa robí tak, že na 1'ahčený útvar, vyrobený v samostatnom procese sa známými spósobmi nanesie adhezívna vrstva, do ktorej sa vnesu vlákenné částice (PAT USA 4 303 706, PAT NSR 2 944 063, Franc. PAT 2 207 212, Franc. PAT 2 468 682, ČSSR PAT 155 435).It is known that the formation of a pile surface on lightweight polymeric materials by flocculation is accomplished by applying an adhesive layer in known manner to a lightweight body, manufactured in a separate process, in which known fibrous particles are introduced (PAT USA 4,303,706, PAT NSR 2). 944 063, French PAT 2 207 212, French PAT 2 468 682, Czechoslovakia PAT 155 435).
Podl'a PAT USA 4 362 774 sa textília s pěnovou vrstvou vyrobí aplikáciou vrstvy pěny na pohybfivý pás textilie, do ktorej sa možu aplikovat vločky za následného vysušenia a kalandrovania.According to U.S. Pat. No. 4,362,774, a foamed fabric is produced by applying a foam layer to a moving web of fabric to which flakes can be applied, followed by drying and calendering.
NSR PAT 3 024 054 popisuje vytváranie vlasového povrchu modakrylovým vlasom na základ z pěnového· 1,2-pofybutadienu, pričom fixácia vlasu sa docieli aplikáciou vysokofrekvenčně) energie a súčasne sa- kalandrovaním vytvoří vzorovaný povrch.NSR PAT 3 024 054 describes the formation of a pile surface with a modacrylic pile based on a foam of 1,2-pofybutadiene, wherein the pile fixation is achieved by the application of high-frequency energy and at the same time by self-calendering a patterned surface.
Nevýhodou postupov, ktoré používajú ako· podklad pre povločkovanie polotovar vyrobený v samostatnom procese, je použitie predovšetkým rozpúšťadlových lepidlových systémov, ktoré sposobujú okrem ekologických a bezpečnostných problémov aj problémy technologické, hlavně pri nanášaní adhezívnej vrstvy na íahčený útvar, z hfadiska dosiahnutia rovnoměrného* povrchu vlasovej vrstvy.A disadvantage of the processes which use a semi-finished blanket in a separate process is the use of solvent-based adhesive systems which, in addition to environmental and safety problems, also cause technological problems, especially when applying an adhesive layer to a lightweight structure. layers.
Pri priamom vločkovaní do nevytrdenej pěny sa nedosahuje dostatečné ukotvenie vlasovej vrstvy.By direct flocculation into the non-torn foam, insufficient anchoring of the hair layer is achieved.
Uvedené a ďalšie nevýhody rieši tento vynález, podfa ktorého sposob výroby fahčeného plošného útvaru s vlasovým povrchom na báze chlór obsahujúcich vinylových homopolymérov* á/alebo* kopolymérov vločkováním a želatináciou sa robí tak, že na separačnú podložku sa nanesie pasta chlór obsahujúceho vinylového polyméru vo formě pěny a/afebo s obsahom 0,5 až 7 °/o hmot. nadúvadla s teplotou uvolnenia plynov v rozmedzí 70 až 220 °C a po jej predželatinácii s případnou čiastočnou alebo úplnou expozíciou nadúvadla sa následné povrství vrstvou pasty chlór obsahujúceho vinylového polyméru, do ktorej sa vnesú vlákenné částice a vytvořený útvar sa želatinu je a připadne súčasne 1'ahčí pri teplote 150 °C až 200 °C počas 1 až 30 minút a následné sa oddělí od separačnej podložky.These and other disadvantages are solved by the present invention, wherein the process for producing a chlorine-containing, lightweight hair-based sheet containing vinyl homopolymers and / or copolymers by flocculation and gelatinization is accomplished by applying a chlorine-containing vinyl polymer paste in the form of and / or or containing 0.5 to 7% by weight of foam; blowing agents with a gas evolution temperature in the range of 70 to 220 ° C and after its pregelatinisation with a possible partial or complete exposure of the blowing agent, the coating is subsequently coated with a layer of chlorine-containing vinyl polymer paste into which the fiber particles are introduced. It is lighter at 150 ° C to 200 ° C for 1 to 30 minutes and subsequently separated from the separation pad.
Výhodou tohoto vynálezu je jeho 1'ahká technologická uskutečnitelnost:, zabezpečenie pevného ukotvenia vlákenných častíc a ekologické a ekonomické výhody oproti doposiaí používaným sposobom.The advantage of the present invention is its low technological feasibility: providing a firm anchoring of the fiber particles and ecological and economic advantages over the methods used hitherto.
Zvolený spůsob dvojvrstvovej základné pre vlasovú vrstvu dovoluje široké variácie v hrúbke, v stupni 1’ahčenia spodnej polymérnej vrstvy, čím sa dosahuje variabilita vlastností celého útvaru a možností jeho* použitia.The chosen method of the two-layer base for the pile layer allows for wide variations in thickness, in the degree 1 '

Prvá kompozícia sa mechanicky naplní vzduchem na kontinuálnom generátore pěny na hustotu 400 g. dm-3 a nanáša sa v hrúbke 5 mm na separačný papier s povrchovým povlakom silikónovej emulzie, predželatinuje sa pri teplote 140 °C po dobu 4 minút. Na predželatinovanú penovú vrstvu sa nanáša druhá kompozícia o hrúbke 0,35 milimetrov, do ktorei sa vnášajú vlákenné častíce na báze polyamidu 6 o jemnosti 22 dtex a dížke 3 mm v jednosmernom elektrickom poli o intenzie 5 kV. cm-1. Povločkovaný útvar sa želatinuje pri teplote 180 stupňov Celsia po dobu 8 minút. Po ochladení a očistění od prebytočnej vločky sa vytvořený plošný útvar oddělí od separačnej podložky.The first composition is mechanically filled with air on a continuous foam generator to a density of 400 g. dm -3 and applied at a thickness of 5 mm to a release paper with a silicone emulsion surface coating, pregelatinized at 140 ° C for 4 minutes. A second 0.35 mm thick composition is deposited onto the pregelatinized foam layer into which the fiber particles based on polyamide 6 having a fineness of 22 dtex and a length of 3 mm in a 5 kV DC electric field are introduced. cm -1 . The flocculated formation is gelatinized at 180 degrees Celsius for 8 minutes. After cooling and clearing the excess flake, the sheet formed is separated from the separation pad.
Vytvořený 1'ahčený plošný útvar má celkovú hrůbku 7 mm a slúži ako podlahovina do mokrých priestorov.The formed 1 'lightweight sheet has a total depth of 7 mm and serves as a floor covering for wet areas.
P r i k 1 a d 7Example 1 and d 7
Postup ako v příklade 6, s tým rozdielom, že k prvej kompozícii sa přidá 0,5 kg azo-dikarbónamidu a 0,25 kg stearátu olovnatého.The procedure as in Example 6, except that 0.5 kg of azodicarbonamide and 0.25 kg of lead stearate are added to the first composition.
Vytvořený plošný útvar má celkovú hrůbku 8 mm a slúži ako podlahovina do vlhkých a studených priestorov.The formed sheet has a total depth of 8 mm and serves as a floor covering in damp and cold spaces.
