Technical Field

[0001] The utility model relates to the technical field of silicone oil production, in particular to a high-speed homogenizing and separating device for the production of silicone oil for polyurethane foam sealant. Background Technique

[0002] Polyurethane foam sealant is a special moisture-curing polyurethane foam system, commonly known as one-component foaming agent, PU sealant, etc., which is the product of the cross-combination of aerosol can sealing technology and polyurethane foam technology. It fills polyurethane prepolymer, foaming agent, catalyst and other components in a pressure-resistant aerosol can, and then sprays from the can into holes or gaps, quickly foaming and expanding and reacting and curing with moisture in the air or on the substrate, having multiple effects such as caulking, bonding, sealing, heat insulation, etc. In one-component polyurethane foam sealant, a matching professional silicone oil should be used to produce foam with uniform and delicate pores and obtain a better caulking effect.

[0003] During the production process of silicone oil, it is necessary to homogenize and separate the silicone oil to separate impurities in the silicone oil. However, in the existing homogenizing and separating machine, the centrifugal cylinder is usually fixed on the transmission mechanism with bolts to achieve the high-speed rotation of the centrifugal cylinder. But this way is not convenient to disassemble the centrifugal cylinder for cleaning or replacement. To solve the above problems, a high-speed homogenizing and separating device for the production of silicone oil for polyurethane foam sealant that is convenient to disassemble the centrifugal cylinder is provided now.
