Abstract:
An insulating product which comprises a fibrous material which is at least partly impregnated with a thermo-plastics substance which, once heated, produces a plurality of encased gaseous voids.
Abstract:
Highly concentrated aqueous polyurethane dispersions are converted into stable foams. Textile fabrics coated with these foams are useful, inter alga, as darkening for glass panes.
Abstract:
Disclosed is a process for making a two or more component foam composite obtained by adhesion of a polyurethane foam onto a substrate comprising the steps of frothing an aqueous polyurethane formulation; applying the froth to a substrate and drying the froth into a foam wherein the foam has a dry density of 35 kg/m 3 to 160 kg/m 3 (2.2-10 Ibs/cft). The process allows the production of foam backed textiles without the need for a flame lamination step or the need for an adhesive layer between the textile and the foam layer and is optionally optimized for superior handling properties for covering polyurethane molded foam cushions.
Abstract translation:公开了一种制备通过将聚氨酯泡沫粘附到基材上获得的两种或多种组分泡沫复合材料的方法,包括起泡水性聚氨酯配方的步骤; 将泡沫施加到基材上并将泡沫干燥成泡沫,其中泡沫体的干密度为35kg / m 3至160kg / m 3(2.2-10磅/英寸2)。 该方法允许生产泡沫背衬的纺织品,而不需要火焰层压步骤或者需要在织物和泡沫层之间的粘合剂层,并且任选地优化用于覆盖聚氨酯模塑泡沫垫的优异的操作性能。
Abstract:
Der Erfindung betrifft ein Verfahren zur Herstellung eines mit einem Harzfilm beschichteten, bevorzugt plattenförmigen Trägermaterials (18), insbesondere einer Schichtstoff-, HDF-, MDF- und/oder Spanplatte, mit den Schritten: Herstellen eines Schaumes auf der Basis eines wässrigen Harzsystems mit Füllstoffen, der hinschtlich seiner Schaumstabilität so ausgebildet ist, dass der Schaum die Füllstoffe fixiert; Auftragen einer Schicht (14) des Schaums auf ein bevorzugt poröses, weiter bevorzugt bahnförmiges Substratmaterial (10), insbesondere Papier oder ein Faservlies, Trocknen des beschichteten Subtratmaterials und Aufpressen des auf eine Restfeuchte getrockneten beschichteten Substratmaterials auf das Trägermaterial (18), insbesondere mit der Substratmaterialseite auf das Trägermaterial (18).
Abstract:
An improved process for applying a treating agent in the form of a foam to fibrous material wherein the improvement comprises applying foam having a blow ratio of from about 2:1 to about 6:1 using equipment designed for the application of liquid treating agents is disclosed.
Abstract:
The present invention relates to a reinforced composite material, comprising an organic polymer, a silicon polymer, and an interphase between said organic polymer and said silicon polymer, wherein said interphase comprises chemical bonds between the organic polymer and the silicon polymer, and to a method to obtain said reinforced composite material. The present disclosure can be used to improve the mechanical properties of silica aerogels by functionalization of textile materials.
