JPS6057916B2 - Roller application method for multi-colored paint - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for applying a multi-colored paint by roller coating.

Multicolored pattern paints are widely used for painting the interior and exterior walls of buildings because the paint film not only has a multicolored pattern finish, but also a three-dimensional pattern finish to some extent.

This method of applying multi-colored paint is called "Zola Coat Gun", which is especially used for multi-colored paint, because the nozzle diameter of the normally used spray gun is small and the paint cannot be discharged.
or a mortar gun. On the other hand, roller painting is becoming popular in architectural painting, but the advantages of roller painting are that it requires almost no curing and is easy to work with, whereas spraying requires extensive curing. It is said that the coating has good properties, does not require much skill on the part of the operator, and can be easily painted on small areas. Therefore, it would be very convenient if roller painting could be used to apply multi-colored paint, but conventionally, when painting with a roller, the roller presses the pattern itself while applying the paint, so it is thought that a uniform multi-colored pattern can be created. The reality is that roller coating has not been seriously considered. ′, R, /↓邊←1, ＾−
y＾↓, 1 ι, - After examining various coating methods, we found that the desired purpose was achieved by applying aggregate-containing paint to the primer layer and then applying multi-colored paint using a special porous roller. I discovered that.

That is, the present invention is characterized in that after the surface to be painted is prepared, a sealer is applied, an aggregate-containing paint is applied with a roller, and then a multi-colored paint is applied with a porous roller. This paper relates to a roller coating method for multi-colored paint. The present invention involves first preparing the surface of the surface to be painted, such as removing dust and dirt from the surface of a building, etc., and then applying an alkaline sealer if the surface to be painted is concrete, or applying an alkaline sealer if the surface is wood, as in normal painting. It is preferable to apply a wood sealer to prevent the material from affecting the top coat and to create a uniform pattern.

Next, the aggregate-containing paint is applied by roller coating for 10 to 30 minutes.
Paint to a dry film thickness of μ. The paint components of the aggregate-containing paint include synthetic resin paints, emulsion paints, etc. used for architecture and wood. As aggregate,
Examples include cold water crushed stone, silica sand, etc., which are usually used in architectural paints, and the content of aggregate in the paint is about 20 to 5% by weight. The roller used for roller coating the aggregate-containing paint may be either a porous roller that is used for roller coating multicolored paint, or a regular Up roller. If the diameter of the aggregate is small, there is no problem with rollers made of UP, but since they contain aggregate, porous rollers are more suitable for use. The porous roller used in the present invention is a roller that is commercially available as a roller for painting aggregates and materials, and is a sponge-like roller made of foam, such as polyurethane, and made porous by the bubbles of the urethane foam. It is.

There are various types depending on the diameter of the bubbles. The aggregate-containing paint is applied with a roller, and after drying, the multicolored pattern paint is applied with a porous roller.

If you use a roller made by Nuppu other than a porous roller, the pattern will be non-uniform and the intended purpose cannot be achieved, so a porous roller is always used. Porous rollers may be the commercially available ones mentioned above, but as the diameter of the air bubbles makes it difficult to form patterns, it is best to avoid rollers that are too small in diameter or too strong. The presence of about 5 to (9) pieces is suitable for the pattern finishing of the present invention. The method of using this porous roller is no different in that it uses a multi-colored paint, and any ordinary painting method may be used. The multicolored paint is not particularly limited, and a wide variety of paints can be used, including water-based multicolored paints that have been developed recently. The first feature of the present invention is that roller coating can provide the same multicolored pattern as spray coating.

This is because a porous roller is used as a painting tool, and the surface of the primer coated with aggregate paint has a certain degree of unevenness, so the roller does not slip even when multicolored paint is applied on top of it. In particular, even when painting vertical areas where the roller easily slides, a multi-colored pattern finish was achieved evenly. Secondly, since multi-colored paint can be applied using rollers, curing problems associated with spraying work can be solved,
This leads to improved workability and, in turn, rationalization of painting. It greatly contributes to the development of society. Furthermore, since the primer layer has an uneven shape, when a multicolored pattern paint is applied thereon, a multicolored pattern with excellent three-dimensional effect can be applied, and both vertical and horizontal areas can be uniformly coated. The present invention will be explained below using examples.

Example 1 After removing dust, oil, etc. from the concrete surface and thoroughly drying the base surface, a commercially available alkaline sealer is applied.

Next, aggregate-containing Iku D Horus White (manufactured by Kansai Paint Co., Ltd., trade name, synthetic resin blended paint. Aggregate used: Sankyo Calcium SK-1 (trade name, made by Sankyo Seifun Co., Ltd., 60-100 mesh - 50 weight) % passing), aggregate content 20% by weight) to a dry film thickness of approximately 20μ with a porous roller (manufactured by Yoshikawa Brush Co., Ltd., material polyurethane, number of holes 8/inch)
Paint with a roller. After the coating film was left for one day and night, Zolacoat (trade name, Kansai Paint Co., Ltd., multicolored paint) was further applied with a roller using the same porous roller. Although the base surface was vertical, a uniform multicolored pattern finish could be obtained without the roller slipping. The multi-colored pattern finish of this product was compared with that obtained by painting Zolacoat with a Zolacoat gun, and the result was comparable. Example 2 After removing dust, oil, etc. from the concrete surface and allowing the base surface to sufficiently dry, a commercially available alkaline sealer is applied.
