摘要:
A flat structure has at least one support layer (I) and at least one transparent coating layer (II), an optional backing layer (III) made of a chemically or mechanically foamed material arranged under the support layer (I), and an optional compact or priming layer (IV) arranged between the support layer (I) and the coating layer (II) and/or between the support layer (I) and the backing layer (III). The coating material for layers (II), (III) and (IV) is made of a combination of (a) epoxidation products of unsaturated fatty acid esters having a chain 8 to 22 carbons long with polyvalent aliphatic alcohols with 2 to 6 C atoms and in average more than one epoxide group per molecule; and (b) partial esters of polycarboxylic acids with polyether polyols containing at least one free carboxylic acid group per molecule and a double bond; (c) an optional water-proofing agent; and (d) other optional additives from the group that consists of fillers, pigments, foaming agents and auxiliary substances. The weight ratio between components (a) and (b) lies between 0.6:1 and 1:1.4.
摘要:
The present invention relates to a method for producing a flat article comprising a material that contains the products of several reactions. The method comprises the following steps: carrying out a pre-cross-linking of a mixture comprising an epoxydation product of a carboxylic acid ester using at least one cross-linking agent in order to form a mouldable material; moulding the mouldable material in the shape of a flat article; and curing the moulded material in order to produce a flat article, wherein the pre-cross-linking reaction is separate from the curing reaction. This invention also relates to a mouldable material that can be stored and to a flat article that can be obtained from the same.
摘要:
The invention relates to materials containing polyreaction products hardened by UV radiation in the presence of at least one UV initiator and/or by electron emission and/or IR radiation, fabrics based on renewable raw materials which contain said materials containing polyreaction products especially in their top layer, and methods for producing said fabrics.

摘要:
The invention relates to materials containing polyreaction products, which include reaction products of dicarboxylic or policarboxylic acids or the derivatives thereof with epoxidation products of carboxylic acid esters and at least one filling material. The invention also relates to a method for the production of said materials as well as to their use in the production of sheet material on the basis of renewable raw materials.
