【発明の名称】ポリオレフィン金属積層板の製造方法
Document Type and Number:
Japanese Patent JPH0710564
Kind Code:
B2
Abstract:
PURPOSE:To make favorable adhesion of polyolefin, which is inexpensive and superior in dielectric characteristics, to a metallic foil and to contrive an improvement in heat resistance, by a method wherein the metallic foil, a specific adhesive film and a fiber are laminated, to which crosslinking treatment is performed. CONSTITUTION:A metallic foil 1, a polyolefin adhesive film 2, glass fiber cloth 3 and a polyolefin sheet 4 are superposed upon one another in order. After those have been integrated through heating and pressurization, crosslinking treatment is performed by holding them within moisture atmosphere. Copper is favorable as a material of the metallic foil and oxygen-free copper is suitable especially for transmission at a high-frequency zone. A copper foil whose surface has been roughed is preferable from a view point of an improvement in adhesion. Then the polyolefin adhesive film is used to make favorable adhesion between the metallic foil and an insulation base material. The glass fiber cloth is indispensable for prevention of a warp or a twist to be generated on a laminated sheet due to a distortion generated at the time of molding processing such as a difference between thermal expansion coefficients or specific heat between those of the metallic foil and insulation base material or in heating-cooling processes.
