Description

Reaction device for producing water-based paint Technical Field The utility model relates to the technical field of water-based paint production equipment, in particular to a reaction device for producing water-based paint. Background The aqueous coating is a coating using water as a solvent or as a dispersion medium. The raw materials of the water-based paint comprise water-soluble resin, water-dispersible pigment and filler, cosolvent, other auxiliary agents and the like. The water paint has the features of water as solvent, saving in resource, no harm to human body, no environmental pollution, high water resistance, high wear resistance, high ageing resistance, high yellowing resistance, fast drying, etc. In the production process of the water-based paint, the raw materials are fully and uniformly mixed by a stirring mechanism. The utility model discloses a reaction unit that production water paint used, it includes the base, base top fixedly connected with support two, support two top fixedly connected with agitator, agitator bottom fixedly connected with drainage tube, drainage tube one end fixedly connected with buffer tube, buffer tube outer wall one side fixedly connected with output tube, equal fixedly connected with support one of output tube outer wall both sides, support one bottom fixedly connected with is in base top one side, the inside sliding connection of buffer tube has the filter tube, filter tube bottom fixedly connected with erection column. The device is inside leading-in buffer tube with water based paint through the drainage tube, filters by the inside filter tube of buffer tube to drive the stirring post through the motor and rotate, accelerate filtration rate, solved the problem that water based paint reaction back probably can contain impurity or solid precipitate, improved water based paint's production quality. In order to maintain the stability of the reaction system, it is necessary to use a neutralizing agent to adjust the pH value when producing the aqueous coating material.
