Description

Technical Field

[0001] The invention relates to the technical field of waterborne epoxy coating production, in particular to waterborne epoxy coating production equipment and a production process. Background Art

[0002] In the production process of waterborne epoxy coatings, some companies will use mechanical methods, which are also called direct emulsification methods. Usually, the epoxy resin is ground with a ball mill, colloid mill, homogenizer, etc., and then the epoxy resin is mixed with an emulsifier, heated to a certain temperature, and water is gradually added under intense stirring to form an epoxy resin emulsion. The advantages of mechanical methods for preparing waterborne epoxy resin emulsions are simple process, low cost, and less amount of emulsifier required. However, the size of the epoxy resin dispersed phase particles in the emulsion prepared by this method is large, about 10μm, the particle shape is irregular, the particle size distribution is wide, the stability of the emulsion obtained is generally poor, and the film-forming properties of the emulsion are not very good. In addition, due to the presence of non-ionic surfactants, the appearance and some properties of the coating will be affected.

[0003] Patent announcement number CN217910138U discloses a stirring device for water-based epoxy coating production, and the utility model relates to the technical field of coating production equipment. The rotating box is arranged inside the box body; the right end of the rotating shaft is rotatably connected with a feed pipe through a bearing; there are several stirring rods, and they are fixedly arranged on the outer wall of the rotating box with equal fillets, the right end of the stirring rod is connected to the inside of the rotating box, and several liquid outlet holes are opened on the outer wall of the stirring rod; the gear is fixedly sleeved on the left end of the rotating shaft on the left side; a rack is slidably arranged in the guide groove, and the rack is meshed with the gear; the adjustment frame is fixedly arranged on the top surface of the rack, and the adjustment frame is an arc-shaped structure; the adjustment block is slidably embedded in the middle of the adjustment frame; a transmission rod is fixedly connected to the output end of the No. 1 motor, and the other end of the transmission rod is hinged to the middle of the adjustment block; while stirring, an emulsifier aqueous solution is added to different positions of the epoxy resin solution, and forward and reverse rotation is adopted to ensure the uniformity of mixing.

[0004] However, we will find that during the production process, the method of adding water under stirring to form an epoxy resin emulsion is not considered comprehensively. The reason is that the temperature of the water is not taken into account. Generally, the temperature of the water added to the equipment is often low. After mixing with the mixture with a higher internal temperature, the temperature of the mixture in the production process is lowered. Although the temperature can be increased by heating later, this is not only a problem of increasing energy consumption, but also will cause the temperature to be insufficient at some time during the epoxy resin emulsification process, affecting the emulsification effect of the epoxy resin.
