Colored paint production reaction kettle convenient for material supplement

Abstract

The invention belongs to the field of paint preparation, and discloses a colored paint production reaction kettle convenient for material supplement. The reaction kettle comprises a reaction kettle body, the top end of the reaction kettle body is provided with a squared feed pipe, the upper end of the feed pipe is provided with a first pipe cover; two sealing plates are arranged in the feed pipe and respectively hinged to the left side and right side of the feed pipe, two sealing plates are both downward inclined, the movable sides of two sealing plates are pressed against each other; a compressed spring is arranged between the lower side of each sealing plate and a position, which is opposite to the lower side of the sealing plate, on the lateral wall of the feed pipe, two ends of two sealing plates are respectively pressed against the front side and rear side of the feed pipe; the reaction kettle also comprises a support rod, the support rod is slidingly connected to the first pipe cover; the lower end of the support rod is provided with a support head, and the external edge of the lower end of the support head is abut on two sealing plates. The provided reaction kettle solves the problems that in the prior art, during the production process of paint, operator needs to wear chemical protective cloth and gas mask for raw material supplement, the operation is complicated, and the production speed is influenced.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to a reaction kettle for color paint production which is convenient for feeding materials. Background technique [0002] Coating refers to a continuous film that covers the surface of an object to be protected or decorated and can form a firm adhesion with the object to be coated. The process of paint production is to crush solid pigment particles by external force and disperse them in resin solution or emulsion to form a uniform and fine suspension dispersion. Its production process mainly includes pre-dispersion, grinding and dispersion, paint mixing, purification and packaging and other steps. [0003] In the process of dispersing and mixing paint, some materials are usually added according to the current situation of the paint. However, in the production process of some paints, especially some colored paints, the raw materials usually contain relatively high toxicit...
