Problems solved by technology

[0004] Soft PVC sheets have various excellent features, but in recent years, there are problems with heavy metal compounds caused by some stabilizers of vinyl chloride resins, VOC problems and endocrine disruptor problems caused by some plasticizers or stabilizers, and problems when burning. The use of vinyl chloride-based resins is gradually being restricted due to the generation of hydrogen chloride gas and other chlorine-containing gases.

Embodiment

[0228] In order to demonstrate this invention more concretely and in detail, an Example is shown below, However, this invention is not limited at all by these Examples. The measurement standards and test methods for the physical properties of the resin sheet-coated metal laminates shown in Examples and Comparative Examples are as follows.

[0229] (a) Production of resin sheet and resin sheet-coated metal laminate

[0230] 1) Raw material mixing and extrusion film making of layer A

[0231] Using isosorbide and 1,4-cyclohexanedimethanol as dihydroxy compounds, a polycarbonate copolymer was obtained by melt polymerization (structural unit derived from isosorbide: derived from 1,4-cyclohexanedimethanol The structural unit=70:30 (mol%)). The obtained polycarbonate copolymer had a glass transition temperature of 120° C. and a reduced viscosity of 0.56 dl / g.

Abstract

The disclosed resin-sheet-covered metal laminate exhibits excellent weatherability, embossing transferability, embossing heat resistance, workability, and surface hardness. Said resin-sheet-covered metal laminate is characterized by the provision of a resin layer (layer A) on a metal plate, said resin layer containing a polycarbonate resin that contains a structural unit derived from a dihydroxy compound having, in part of the structure thereof, the site represented by formula (1). (However, the site represented by formula (1) is not part of -CH2-O-H).

Description

technical field [0001] The present invention relates to a resin sheet-coated metal laminate and a method for manufacturing the same. The resin sheet-coated metal laminate can be applied to casings of electrical and electronic equipment or mobile phones, panels of plywood furniture or steel furniture, and integral bathrooms. Panels for walls or ceilings, building materials for interior doors or partitions, front doors and vertical panel members around them that require high weather resistance, etc., and this resin sheet covers the embossing of the metal laminate to improve design Processability is also excellent. Background technique [0002] In the above-mentioned applications, soft vinyl chloride resin sheets (hereinafter referred to as "soft PVC sheets") coated with embossed designs on synthetic resin molded products or plywood, wood fiber boards, and metal plates have been used. ) made of materials, and coated metal plates, etc. [0003] In addition, for materials with ...
