Description

Technical Field

[0001] The utility model relates to the technical field of acrylic rubber production, in particular to an emulsion post-processing device for acrylic rubber production. Background Art

[0002] Acrylic rubber is an elastomer obtained by copolymerization with acrylate as the main monomer. Its main chain is a saturated carbon chain and the side group is a polar ester group. It usually requires the participation of vulcanization point monomers to make it easy to vulcanize. Since the primary structure is a saturated carbon chain and polar side groups, it has excellent heat resistance, aging resistance and oil resistance.

[0003] According to the publication number CN217189037U, a technical field of acrylic rubber production equipment is disclosed, which specifically relates to an emulsion post-processing device for acrylic rubber production. The emulsion post-processing device for acrylic rubber production includes an aging kettle, a stripping kettle, a coagulation kettle and a filter tank connected in sequence; the feed port of the aging kettle is connected to the polymer emulsion pipeline, the aging kettle and the stripping kettle, and the stripping kettle and the coagulation kettle are connected through an emulsion delivery pipeline, the emulsion delivery pipeline is provided with a protective sleeve on the outside, and an electric heating strip is provided between the emulsion delivery pipeline and the protective sleeve; the discharge port of the coagulation kettle is connected to the filter tank, the liquid discharge port of the filter tank is connected to the washing water recovery pipeline, and the solid discharge port of the filter tank is connected to the raw rubber particle discharge pipe. The emulsion post-processing device of the utility model avoids emulsion demulsification when the emulsion is transported at low temperature, especially below zero degrees, reduces the difficulty of pipeline cleaning, and improves the quality of raw rubber particles.

[0004] However, the above device still has shortcomings. By using an electric heating strip installed outside the emulsion delivery pipeline to heat the emulsion after the acrylic rubber is produced, demulsification can be prevented. However, the pipeline heating strip cannot heat the emulsion evenly, which will cause the emulsion to stick during pipeline transportation and be difficult to clean. Secondly, it is difficult to maintain the heating strip in the delivery pipeline, which is very inconvenient. Utility Model Content
