Description

Technical Field

[0001] The utility model relates to a mixing device for producing polyurethane resin, in particular to a mixing device for producing polyurethane resin for solvent-free synthetic leather, belonging to the technical field of polyurethane resin production. Background Art

[0002] Polyurethane resin is a polymer compound that can be made into polyurethane plastics, polyurethane fibers, polyurethane rubbers and elastomers. It has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, smaller compression deformation, and good heat insulation, sound insulation, shock resistance and anti-toxic properties. It is often used as a processing material for solvent-free synthetic leather. However, when polyurethane resin is produced in the chemical industry, it is necessary to mix multiple raw materials.

[0003] In the actual operation of traditional mixing equipment for polyurethane resin production, in order to limit and fix the mixing tank on the equipment, a cable tie is generally used to tie the mixing tank to the equipment frame. However, due to the large elasticity of the cable tie, it is difficult to limit the mixing tank well. When the stirring paddle rotates at high speed, the entire mixing tank is prone to vibration. When the material inside the mixing tank is initially unevenly distributed or is hit by external force, it is more likely to cause some deviation, which will cause the stirring paddle to scrape the inner wall of the mixing tank, which not only affects the mixing process, but also causes damage to the equipment. Utility Model Content
