Problems solved by technology

The content of zinc in the coating is usually more than 70%, resulting in too high zinc powder content in the coating, the coating is easy to be porous, and the adhesion is reduced, which affects the bonding force between the upper coating and the zinc-rich coating, making the coating's corrosion resistance reduced performance
[0005] The existing powder coating production process is inconvenient to quickly stir and fuse the raw materials, and the chemical resistance of the coating, especially the alkali resistance, is not significant. Therefore, the present invention provides an environment-friendly epoxy zinc-rich anti-corrosion powder coating. Production equipment and production process

Abstract

The invention relates to the technical field of paint production, and discloses production equipment and a production process of an environment-friendly epoxy zinc-rich anti-corrosion powder paint.The production equipment comprises a stirring barrel, a heating ring is installed on the inner side wall of the stirring barrel, and a threaded connector is formed in one side of the heating ring; the surface of the threaded connector is in threaded connection with a barrel cover through a threaded connector. According to the production equipment of the environment-friendly epoxy zinc-rich anti-corrosion powder coating, through cooperative arrangement of the stirring barrel, the motor, the transmission rod, the rotating rod and the stirring blades, when the equipment is used, the motor is externally connected with a power supply, then required raw materials are put into the stirring barrel, and then the raw materials are stirred through the rotating rod and the stirring blades, so that the effect of stirring and mixing the raw materials is achieved; through the arrangement of a heating ring, the heating ring is externally connected with a power supply during use to heat raw materials, so that the raw materials are fused more quickly, and through the cooperative arrangement of a paint discharge pipe, a valve and a paint box, a user can discharge paint conveniently during use.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to production equipment for an environment-friendly epoxy zinc-rich anticorrosion powder coating, and also relates to a production process for an environment-friendly epoxy zinc-rich anticorrosion powder coating. Background technique [0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] As we all know, powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film, and...
