    摘要： Polyisocyanate preparations containing latent tin catalysts are made from an organic polyisocyanate and a reaction product of a sulfonyl isocyanate and an organic tin catalyst in which at least one tin-oxygen bond is present. The organic tin catalyst preferably contains a tin-alkoxy, tin-siloxy, distannoxane and/or tin-carboxylate group. The reaction product of a sulfonyl isocyanate with a tin-carboxylate must generate carbon dioxide during its formation. The sulfonyl isocyanate and organic tin compound are used in quantities such that at least one isocyanato-sulfonyl group is present for each tin-oxygen bond. These polyisocyanate preparation are storage stable and may be used to produce adhesives, coatings and foams.

    摘要翻译： 含有潜在锡催化剂的多异氰酸酯制剂由有机多异氰酸酯和磺酰基异氰酸酯与存在至少一个锡 - 氧键的有机锡催化剂的反应产物制成。 有机锡催化剂优选含有锡 - 烷氧基，锡 - 甲硅烷氧基，二锡氧烷和/或锡 - 羧酸酯基团。 磺酰基异氰酸酯与锡 - 羧酸盐的反应产物在其形成过程中必须产生二氧化碳。 磺酰基异氰酸酯和有机锡化合物的用量使得每个锡 - 氧键存在至少一个异氰酸基 - 磺酰基。 这些多异氰酸酯制剂是储存稳定的，可用于生产粘合剂，涂料和泡沫。

    摘要： A process for the production of foam cushions from different fluid reaction mixtures comprising introducing a first reaction mixture and at least one other reaction mixture into a mold cavity and leaving the mixtures to react to form a cushion having zones of differing elasticity or firmness, characterized in that one of the two reaction mixtures is not introduced into the mold cavity until it has creamed up and is already viscous, and in that the second reaction mixture, which has not creamed up, is introduced at the same time or later.

    摘要： A vacuum mold and process for manufacturing a textile-covered cushion. The process broadly comprises back foaming, wherein (i) the cover is placed on the edge of a vacuum molding part at least partly containing a mold cavity and is stretched before a vacuum is applied to the mold cavity, (ii) the cover is sucked into position, (iii) a foamable reaction mixture is then applied to the back of the cover and (iv) when the reaction mixture has set to form the foam core, the cushion is removed from the mold, the improvement wherein prior to the application of the vacuum to the mold cavity, the cover is brought into contact with at least one moveable section of the wall of the mold cavity as it is positioned over the mold cavity, the cover is fixed to this section and the section together with the cover fixed thereto is then moved into the molding position.

    摘要： The present invention is directed to an apparatus for the production of foam cushions having textile covers by inserting a textile cover into a mold cavity having gates which project into the mold cavity, initially preforming the textile cover by applying a vacuum through holes in the mold cavity such that the textile cover conforms to the contour on both sides of the gates, clamping the textile cover against the gates, further positioning the textile cover such that it conforms to the contours of both the gates and the mold cavity, releasing the clamps and introducing a foam-forming reaction mixture into the mold cavity. The present invention is also directed to a form tool having gates, means for applying a vacuum through holes in the mold cavity in gates and clamping means for clamping the mold cover to the gates.
