Description

Paint stirring device and stirring method using the same {AN APPARATUS FOR MIXING PAINT AND METHOD OF MIXING PAINT USING THE SAME}

The present invention relates to a paint stirring device and a stirring method using the same.

In general, as a method of coating a marine paint, an airless coating method in which the paint is sprayed through a spray gun by applying pressure to the paint is currently most widely used.

In recent years, solvent-free drawing materials are widely used in ship painting work, and since solvent-free drawing materials do not use solvents, which are volatile organic compounds, they are less harmful to the human body and have a low risk of fire, and there are no environmental problems such as air pollution, and the solid content is high. It is preferred because of its simple coating process.

However, since such a solvent-free coating material does not contain a volatile solvent, the viscosity is high, and during painting, the viscosity must be lowered to maintain an appropriate viscosity so that it can be smoothly sprayed through the spray gun.

At this time, during the painting operation, when the viscosity of the solvent-free material is high, spraying defects may occur in the spray gun, and when the viscosity is too low, there is a problem that the painting quality is deteriorated due to a decrease in flowability.

1 is a flowchart illustrating a process of stirring the paint using a conventional stirrer and supplying the paint to a spray gun.

Referring to FIG. 1, in the prior art, a paint container was opened (S10), and a curing agent was added to the subject of the solvent-free drawing material contained in the paint container, and then the subject and the curing agent of the solvent-free drawing material were stirred using a stirrer or the like (S20).

In addition, a sprayer is provided on the paint hose that connects the paint container and the spray gun. By adjusting the pressure of the sprayer (S30), the solvent-free paint is sprayed through the spray gun by supplying the solvent-free paint from the paint container to the spray gun. It can be done (S40).

In this process, if the spraying efficiency of the spray gun is low due to the high viscosity of the solvent-free paint, the paint container is heated for a predetermined time (S50), and the temperature of the solvent-free paint contained in the paint container is measured (S60), and it is determined that the viscosity has decreased. Then, the solvent-free paint was supplied to a spray gun through a sprayer and sprayed.

However, in such a conventional paint painting operation, the process of heating the paint container must be repeated whenever the spraying efficiency of the spray gun decreases, and the exact viscosity of the solvent-free paint cannot be confirmed, so that it can be sprayed under smooth conditions through the spray gun. It is quite difficult to adjust to an appropriate viscosity, and thus there is a problem that the coating quality is deteriorated.

In addition, in order to adjust the viscosity of the paint, it is necessary to repeatedly take the paint container out of the stirrer and take it to a separate heater to heat the paint container, so that the work time is excessively consumed and the work efficiency is deteriorated.

In the present invention, a paint stirring device and a stirring method using the same, specifically, agitating the paint accommodated in the paint container with a viscometer combined stirrer, measuring the viscosity, and adjusting the heating amount to maintain the paint at a preset appropriate viscosity, A paint stirring device capable of supplying a paint having an appropriate viscosity so that the paint is sprayed under a smooth condition through a spray gun during paint work, and a stirring method using the same are provided.
