Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin preparation, and more specifically to a storage-resistant low-temperature curing epoxy resin preparation stirring and mixing device. Background Art

[0002] Epoxy resin is a high molecular polymer, which is a condensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of the epoxy group, it can be opened by a variety of compounds containing active hydrogen, and cured and cross-linked to form a network structure. Storage-resistant low-temperature curing epoxy resin is an epoxy resin with a curing agent added. It can be quickly cured at a lower temperature and will not damage heat-sensitive precision electronic components. It is easy to store after curing. Storage-resistant low-temperature curing epoxy resin requires the use of stirring and mixing equipment during the processing.

[0003] In the existing stirring and mixing equipment, in order to prevent the materials from solidifying and mixing during the stirring process, the stirring equipment needs to be heated. During the heating process, the heat gradually enters the inside of the stirring equipment from the outside, and the center of the material will be difficult to heat and unevenly mixed. In addition, water vapor will carry the raw materials and dissipate during the heating process, resulting in a reduction in moisture and material during the mixing process, resulting in reduced quality of the finished product and increased costs.

[0004] In view of this, the present application proposes a storage-resistant low-temperature curing epoxy resin preparation stirring and mixing equipment. Utility Model Content
