Paint reaction kettle

Abstract

The invention discloses a paint reaction kettle, comprising a barrel body, a stirrer, a feeding hole and a discharge hole, wherein the stirrer is arranged in the barrel body; the feeding hole is formed in the top of the barrel body; the discharge hole is formed in the bottom of the barrel body; the stirrer comprises a stirring shaft; a small paddle and a large paddle are sequentially arranged on the stirring shaft from top to bottom; a plurality of connecting rods are evenly distributed on the stirring shaft between the large paddle and the small paddle; a scraper plate which contacts the inner wall of the barrel body is arranged at the tail end of each connecting rod; a side stirring device is arranged between the end of the large paddle and the stirring shaft; and a content gage which is communicated with the barrel body is arranged on the barrel body. According to the paint reaction kettle, the paint is relatively even to stir; the stirring effect can be examined in real time; the product performance is uniform; the product is not coked; a vortex effect is also generated during stirring; and the material turning and mixing effects are further improved.

Description

technical field [0001] The invention relates to the field of paint processing, in particular to a paint reaction kettle. Background technique [0002] Coatings are prepared by mixing special resins, pigments and fillers, curing agents and other additives in a certain proportion, and then through hot extrusion, crushing and sieving. They are stable in storage at room temperature. After electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dipping (thermoplastic method), they are heated and baked to melt and solidify to form a flat and bright permanent coating film to achieve decorative properties. And anti-corrosion purposes, one of the key materials in powder coatings such as epoxy / polyester and polyester / TGIC used in large quantities is polyester resin, and the production process generally adopts a three-pot reaction system (beating pot, ester Chemical / transesterification kettle, polycondensation kettle / ); the agitator of the reactor is a single...
