具有改进的耐候性的层压制品
摘要：
本发明涉及一种制造耐候性层压制品的方法，该层压制品包括位于载体层上的树脂浸渍纤维层，优选树脂浸渍的饰面纸层。本发明还涉及可通过本发明方法获得的层压制品，以及用于制造该耐候性层压制品的层压制品半成品和所述层压制品的用途。所述方法包括如下步骤：提供树脂浸渍纤维层；在第一固化步骤中使树脂浸渍纤维层的树脂固化，其中在所述第一固化步骤中对树脂浸渍纤维层施加接触压；在至少部分固化的树脂浸渍纤维层上施加树脂涂布层；在独立的第二固化步骤中使树脂涂布层的树脂固化；以及在第一固化步骤之前、之中或之后将树脂浸渍纤维层层压到载体层的至少一个表面上，或者在第二固化步骤之前、之中或之后将经固化和涂布的树脂浸渍纤维层层压到载体层的至少一个表面上。
摘要（英）：

The invention relates to a process for the manufacture of a weather resistant laminate comprising a resin impregnated fibrous layer, preferably a resin impregnated decorative paper layer on a carrier layer. The invention further relates to laminates obtainable with the process according to the invention, to an intermediate laminate for use in the manufacture of the weather resistant laminate and to the use of said laminates. The process comprises the steps of providing a resin impregnated fibrous layer, curing the resin of the resin impregnated fibrous layer in a first curing step, wherein in said first curing step a contact pressure is applied to the resin impregnated fibrous layer, applying a resin coating layer on the at least partially cured resin impregnated fibrous layer, curing the resin of the resin coating layer in a separate second curing step and laminating the resin impregnated fibrous layer on at least one surface of a carrier layer before, during or after the first curing step, or laminating the cured and coated resin impregnated fibrous layer on at least one surface of a carrier layer before, during or after the second curing step.
