Abstract

Disclosed is an aqueous coating agent which enables the formation of a good coating film by an in-mold coating technique, and which can be used in an in-mold coating process comprising applying the coating agent on the inner wall of a cavity within a mold to form a coating film and injecting a filler material into a gap between an object to be treated and the coating film, thereby forming a coating film comprising the filler material and the above-mentioned coating film as the outermost layer on the surface of the object for the purpose of solving a problem of the disposal of an organic solvent. The aqueous coating agent is mainly composed of water and a film forming aid. When 10 g of the aqueous coating agent is placed in an acrylic pipe having a height of 1 m and an inner diameter of 34 mm and the pressure in the acrylic pipe is reduced to form a foam, the height of the foam is 400 mm or more.

Description

technical field [0001] The invention relates to a water-based coating agent used in an in-mold coating method. In the in-mold coating method, after the coating agent is applied to the inner wall of a mold cavity in a mold to form a coating film, it is applied to the object to be treated and Filling material is injected into the gap between the coating films, thereby forming a coating film formed by the filling material and the coating film as the outermost layer on the surface of the object to be treated. Coated film molded product obtained by in-mold coating method of water-based coating agent. Background technique [0002] For example, in the manufacturing method of the steering wheel of an automobile, after the core rod of the steering wheel is installed in the mold cavity, a resin material is injected into the mold cavity to harden to form a resin layer. From the point of view of good touch, polyurethane resin is used as the resin material, but polyurethane resin has th...
