Document Type and Number:
Japanese Patent JP7473492
Kind Code:
B2
Abstract:
This flocked spring (30) has a spring body (31), a cationic electrodeposition coating layer (32) disposed on the surface of the spring body (31), an adhesive layer (33) disposed on the surface of the cationic electrodeposition coating layer (32), and a flocking layer (34) composed of a flocking filler fixed to the adhesive layer (33). The surface roughness Rz of the cationic electrodeposition coating layer (32) on which the adhesive layer (33) is disposed is 19.6 μm or greater. This method for producing a flocked spring has a cationic electrodeposition coating step for performing a cationic electrodeposition coating process on a spring body to form a film of an electrodeposition coating on the surface of the spring body, an adhesive application step for applying an adhesive that includes a roughening solvent to the surface of the coating film, a flocking step for bonding a flocking filler to the surface to which the adhesive has been applied, and a baking step for heating the spring body to which the flocking filler is bonded.
