摘要：
본발명은열가소성물질을포함하는스트럿(strut)에의해연결된 2 이상의금속외피(shell) 및경질폴리우레탄폼을포함하는심재(core)를포함하는복합프로파일형재를제조하는방법에관한것으로, 상기방법은금속외피들에의해형성된중공공간내로경질폴리우레탄폼의출발성분들을도입하여경질폴리우레탄폼이형성되는단계, 및분말코팅또는베이킹에나멜을사용하여복합프로파일형재의외측표면에표면코팅을후속적용하는단계를포함하고, 경질폴리우레탄폼은하기성분들: A) 하나이상의폴리이소시아네이트, B) 이소시아네이트에대하여반응성이있는하나이상의다작용성화합물, C) 적어도포름산을포함하는하나이상의발포제, D) 임의로하나이상의난연제, E) 임의로하나이상의촉매및 F) 임의로추가보조제또는첨가제의 반응에의해수득되며, 경질폴리우레탄폼의출발성분들은무기충전제를포함하지않는다.
摘要（英）：

The present invention relates to a method for producing a composite profile shape member comprising a core material (core) comprising two or more of the metal shell (shell) and rigid polyurethane foam are connected by a strut (strut) comprising a thermoplastic material, the method comprising: It is subsequently applied to the surface coating on the outside surface of the composite profile shape member by the introduction of the starting components of the rigid polyurethane foam into the hollow space formed by the metal sheath using the steps that are the rigid polyurethane foam is formed, and a powder coating or baking enamel comprising the step of, and the rigid polyurethane foam has the following components:
A) at least one polyisocyanate,
B) isocyanate at least one polyfunctional compound which is reactive with respect to,
C) at least one blowing agent comprising at least formic acid,
D) optionally at least one flame retardant,
E) optionally at least one catalyst and
F) optionally adding supplements or additives
The reaction may be obtained by a,
Starting components for rigid polyurethane foams do not contain inorganic filler.
