Technical Field

[0001] The utility model belongs to the field of synthetic leather treatment and mixing, in particular to a mixing device used for the production of water-based polyurethane synthetic leather treatment agents. Background Art

[0002] The basic principle of solvent synthetic leather is the online rapid reaction molding after the prepolymer is mixed and coated. Two or more prepolymers and combination materials are added to the mixing head in a set ratio, mixed evenly and then injected and coated on the base cloth or release paper. After entering the drying oven, the low molecular prepolymer begins to react and gradually forms a high molecular polymer, which is formed in the reaction process. When the synthetic leather is coated, in order to better mix the stock solution, a corresponding mixing device is required to mix the materials to be coated. When the existing mixing device is used, due to its lack of an effective uniform material distribution structure, the fixed position feeding device will cause the material entering the barrel to accumulate when feeding into the mixing device, which is not conducive to mixing by the stirring device and has limitations.
