Description

Technical Field

[0001] The present invention relates to the technical field of polyurethane foaming agent preparation, and particularly relates to a foaming device for preparing polyurethane foaming agent. Background Art

[0002] The polyurethane foaming technology is a process of foaming isocyanate prepolymer through chemical reaction. In this process, isocyanate molecules form polyurethane foam through chain transfer reaction, and this foam has excellent physical properties such as low density, high elasticity, good wear resistance and corrosion resistance.

[0003] In the preparation process of polyurethane foaming agent, the uniform mixing of materials and bubble control are the key factors affecting product quality. Traditional foaming devices mostly use one-way stirring or fixed spiral blades for mixing, but such devices have problems such as low mixing efficiency, poor material fluidity, and easy generation of bubbles.

[0004] Especially when dealing with materials with high viscosity or multi-phase mixing requirements, traditional devices are difficult to achieve sufficient convection, resulting in uneven mixing and affecting the performance of the foaming agent. In addition, the generation of bubbles will reduce the density of the product, and the existing technology lacks a mechanism for dynamically adjusting stirring parameters and actively suppressing bubbles, making it difficult to meet the production requirements of high-quality foaming agents.
