Title
(EN) Translucent polyurethane or poly-isocyanurate foams
(ZH) 半透明聚氨酯或聚异氰脲酸酯泡沫材料
Abstract
(EN)
The present invention relates to a process for producing translucent polyurethane and poly-isocyanurate foams by reaction of a component A comprising A1 at least one polyol reactive with the componentB; A2 optionally at least one amine; A3 water and optionally formic acid; A4 at least one foam stabilizer; A5 optionally auxiliary and/or additive substances; A6 optionally at least one flame retardant; A7 at least one catalyst; and a component B comprising B1 at least one aliphatic or cyclo-aliphatic polyisocyanate component or a combination thereof; and B2 optionally at least one hydrophilizedisocyanate; and B3 less than 20 parts by weight of an aromatic polyisocyanate component, wherein the parts by weight of B3 are based on the sum of the parts by weight of B1 to B3 normalized to 100 parts by weight, characterized in that the reaction of the component A with the component B is carried out at an isocyanate index of at least 150, wherein the obtained translucent polyurethane and poly-isocyanurate foams have a light transmission according to EN ISO 13468-2:2006 of at least 10% and a haze of at least 70%, determined according to ASTM D1003-13, in each case measured at a layer thickness of 20 mm. The present invention further relates to polyurethane and poly-isocyanurate foams obtained by the process and to the use thereof as a construction element, as a wall element, as a floor element, in buildings, in vehicles or lamps.
