They are usually made by mixing polyurethane prepolymer modified epoxy resin with self-made curing agent in a ratio of 10:1 to 1:1 (by weight) to form a curing system with high temperature resistance, good toughness and high reactivity. In the production process of epoxy adhesives, the mixing and preparation equipment is a very important piece of equipment.

In existing technologies, the mixing of raw materials is uneven due to the presence of large air bubbles within the raw materials. Furthermore, since epoxy adhesives are quite viscous, the equipment is not convenient for stirring and requires precise and rapid temperature control. Therefore, we propose an epoxy adhesive production mixing device. Utility Model Content
