Description

Stirring Device for Binary Liquid Type Water-based Adhesive The present invention relates to a stirring device for a two-component water-based adhesive used when attaching a skin material to a core member during the manufacturing process of automobile interior materials. The two-component water-based adhesive used to bond the surface material of automotive interior materials to the core consists of a urethane resin as the main component and a hardener. The main component and the hardener are mixed and stirred in a predetermined ratio and used within an appropriate time. The mixing ratio is determined manually, and the mixing is performed manually for a considerable amount of time. However, manual stirring presents problems such as difficulty in achieving precise mixing and difficulty in achieving uniform mixing. FIG. 1 is a drawing showing the front view of a stirring device for a two-component aqueous adhesive according to the first embodiment of the present invention. FIG. 2 is a drawing showing the right side of a stirring device for a two-component aqueous adhesive according to the first embodiment of the present invention. FIG. 3 is a block diagram showing the configuration of a stirring device for an aqueous adhesive according to the first embodiment of the present invention. FIG. 4 is a flowchart showing a stirring method for a two-component aqueous adhesive according to the first embodiment of the present invention. FIGS. 5 to 10 are schematic diagrams illustrating a stirring method for a two-component aqueous adhesive according to the first embodiment of the present invention. FIG. 11 is a drawing showing a curing agent supply unit according to a second embodiment of the present invention. FIG. 12 is a block diagram showing a cleaning unit according to a third embodiment of the present invention. FIG. 13 is a drawing showing a stirring device for a two-component aqueous adhesive according to the fourth embodiment of the present invention. Hereinafter, a manufacturing apparatus (1) for a two-component aqueous adhesive according to an embodiment of the present invention will be described in detail with reference to the attached drawings.
