专利汇可以提供Manufacture of copper-decorated eaves trough专利检索,专利查询,专利分析的服务。并且PURPOSE: To cheaply manufacture the title eaves trough in simple processes by subjecting the surface of a copper foil to chemical treatment such as sulfurization or oxidation to color the surface; coating the colored surface with a transparent protective film to form a sheet; and sticking the sheet to the outside of a plastic pipe.
CONSTITUTION: The surface of copper foil 1 is subjected to chemical treatment such as sulfurization or oxidation to color the surface black or green. Colored surface 2 is dried, optionally treated with a rust inhibitor, coated with curing type clear lacquer such as ultraviolet-curing coating or urethane resin coating, and cured to coat transparent protective film 3 as well as to prevent weathering discoloration of surface 2, thus forming sheet 4. The lacquer is sufficiently cured not to be damaged by a liquid adhesive. With film 3 facing outward, sheet 4 is sticked to the outside of plastic pipe 5 with the adhesive. The joint of sheet 4 is straightened so that it is hidden to the back side at the time of execution.
