Abstract

Ved en fremgangsmåte til fremstilling av en skum- plastplate (1) blir et utgangsmateriale anbragt mellom to dekklag (3, 4) og en kjemisk oppskummingsreaksjon av utgangsmaterialet innledet. Som dekklagmateriale for platen anvendes en bærer av et ikke-vevet eller vevet tekstilstoff med et belegg som består av et pulver- formet anorganisk materiale og ytterligere bestanddeler. Skumplastplaten (1) far en kjerne (2) av oppskummet plast som er anordnet mellom to lag (3, 4) av dekk- lagmateriale. For forbedring av bruksegenskapene av skumplastplaten blir intensiteten av oppskummingsreaksjonen redusert i området for minst ett dekklag (3, 4) ved fremstillin- gen. Det pulverformede anorganiske materiale reagerer herunder basisk eller inneholder i det minste en basisk reagerende andel. Den oppskummede plast får dermed en uregelmessig porestørrelsesfordeling over tykkelsen av kjernen (2), idet den midlere porestørrelse i området for minst ett dekklag (3, 4) er mindre enn i midten (I) av kjernen (2).In a process for preparing a foam plastic sheet (1), a starting material is placed between two cover layers (3, 4) and a chemical foaming reaction of the starting material is initiated. As a covering material for the plate is used a carrier of a non-woven or woven textile fabric with a coating consisting of a powdered inorganic material and additional components. The foam plastic sheet (1) has a foamed plastic core (2) arranged between two layers (3, 4) of cover layer material. In order to improve the application properties of the foam plastic sheet, the intensity of the foaming reaction is reduced in the area of at least one covering layer (3, 4) during manufacture. The powdered inorganic material reacts below basic or contains at least a basic reacting proportion. The foamed plastic thus has an irregular pore size distribution over the thickness of the core (2), the mean pore size in the region of at least one covering layer (3, 4) being smaller than in the center (I) of the core (2).
