[0002] Epoxy resin is a kind of polymer, which refers to the general name of a class of polymers containing more than two epoxy groups in the molecule. It is the polycondensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of the epoxy group, it can be ring-opened by a variety of compounds containing active hydrogen, and cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin. In the production and processing process of epoxy resin, a mixing reactor is needed to assist in mixing the water-based epoxy curing agent and epoxy resin, so that the epoxy resin undergoes a chemical cross-linking reaction under a certain environment and changes into an insoluble and infusible three-dimensional network structure after curing.

[0003] When the existing epoxy resin heating and mixing reactor is used for mixing, a driving motor is used to drive a multi-layer stirring blade group to stir in the reactor. However, after the initial stirring, some water-based epoxy resins may gradually accumulate locally at the bottom of the reactor, and the stirring blade group is also difficult to stir the raw materials at the bottom of the reactor, making it difficult for the raw materials at the bottom of the reactor to be fully mixed, resulting in a general mixing effect.

[0004] Therefore, it is necessary to provide a new epoxy resin heating and mixing reactor to solve the above technical problems. Content of the Utility Model

[0025] The change in negative pressure on both sides of the piston 42 causes the raw materials at the bottom end of the kettle body 1 to be transported to the upper end position of the kettle body 1. While stirring and mixing evenly, it can ensure that the raw materials inside the kettle body 1 can be fully mixed under the action of the stirring blade group, so that the reaction can be fully carried out.

[0026] Reference Figure 1 and Figure 3 As shown, two upper pipes 52 are symmetrically arranged on the upper side wall of the kettle body 1, and two interfaces are symmetrically arranged on the lower side wall of the kettle body 1.

[0027] It should be noted that: the raw materials at the lower end of the kettle body 1 flow out through the two interfaces, and at the same time, they flow back to the top end of the kettle body 1 through the two upper pipes 52.

Use the middle seat 61 to drive the frame plate 44 to reciprocate accordingly, so that the frame plate 44 drives the two slide rods 43 to slide relative to the tube walls at both ends of the horizontal tube 41. The opposite ends of the two slide rods 43 jointly drive the piston 42 to reciprocate inside the horizontal tube 41. Utilize the negative pressure change on both sides of the piston 42 to enable the raw materials at the bottom end of the kettle body 1 to alternately pass through the two straight tubes 5 and the two first connecting tubes and be conveyed into the horizontal tube 41, and then alternately pass through the two branch tubes 51 and the two second connecting tubes and be respectively conveyed to the upper end position of the kettle body 1.
