JPS60106864A - Paint which prevents trace of sticked paper from remaining - Google Patents

Abstract

PURPOSE:To provide the titled paint which allows paper stuck onto a building to be easily peeled off without leaving traces of the stuck paper remaining, by adding a relatively large quantity of a silicone oil and/or wax to a specified room-temperature drying paint. CONSTITUTION:10-70pts.wt. (per 100pts.wt. resin component of paint) silicone oil such as KF 356 (a product of Shinetsu Kagaku K.K.) and/or wax such as liquid paraffin are/is blended with a room-temperature drying paint for coating structures, selected from among acrylic lacquer, nitrocellulose lacquer, acrylic emulsion paint and epoxy emulsion paint.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paint for preventing stickers from being pasted on buildings, which can be easily peeled off and do not leave any traces.

Advertisements, promotional flyers, etc. pasted on utility poles, lampposts, distribution towers, pedestrian bridges, bridge piers, gates, and other structures not only detract from the aesthetics, but also require a huge amount of labor and expense to remove them. become. Moreover, it is difficult to remove the sticker completely without leaving traces of the sticker, so some parts of the sticker remain attached.
Often.

Therefore, the present inventors investigated a paint that can be easily peeled off even if a sticker is pasted and does not leave traces of the sticker, and as a result, the present invention was achieved. That is, the present invention relates to a paint for preventing pasting marks, which is made by adding 10 to 70 parts by weight of silicone oil and/or wax to 100 parts by weight of the resin in a specific room-temperature-drying paint.

The present invention achieves this objective by adding silicone oil and/or wax to certain room temperature drying paints that are conventionally applied to buildings. The amount of silicone oil and/or wax added is in the range of 10 to 70 parts by weight based on 100 parts by weight of the resin content of the paint that dries at room temperature. If the amount added is less than 10 parts by weight, it will not have a significant effect on preventing paper sticker marks, and if it exceeds 70 parts by weight, the compatibility with the paint will deteriorate, which is not preferable. Conventionally, when silicone oil or wax is used as an additive in the paint field, it is intended to be used as a color separation prevention agent for paints, a surface smoothing agent for paint films, etc. It is several percent by weight or less.

On the other hand, in the present invention, an unexpected effect was brought about by significantly increasing the amount of silicone oil or wax added.

As the wax, liquid paraffin, polyethylene wax, or the like is used.

The specific room temperature drying paint used in the present invention is a paint selected from acrylic lacquers, nitrocellulose lacquers, acrylic emulsion coatings and epoxy emulsion coatings.

The paint for preventing pasting marks of the present invention is produced by thoroughly stirring the above-mentioned room-temperature-drying paint, silicone oil, and/or wax to uniformly disperse the paint, and then applying it to a building using a normal brush.
Paint by roller painting, spray painting, etc.

In the present invention, by adding a specific amount of silicone oil and/or wax to the paint, the resulting paint film has
Even if a sticker is pasted, peeling work is easy and no trace of the sticker remains. Therefore, the present invention greatly contributes to preserving the aesthetic appearance of the city.

The present invention will be explained below with reference to Examples and Comparative Examples.

[Metalact H-5J (part name manufactured by Kansai Paint ■, metal pre-treatment paint) was applied to the aluminum plate.

After drying for 2 hours, 30 parts by weight of silicone KF356 (part name manufactured by Shin-Etsu Chemical, silicone oil) was added to 100 parts by weight of the resin.

It was spray coated to a dry film thickness of μ and allowed to dry for - weeks.

Next, commercially available laundry glue was applied to the coated surface, and then imitation paper was attached. A peel test of the imitation paper was then conducted based on the number of openings over time after application. The results are shown in Table 1.

Example 2 "Metalact H-5" was painted on a galvanized iron plate, and after drying for 2 hours, silicone KF-362 < Shin-Etsu Chemical (product name silicone oil manufactured by II) and liquid paraffin were applied to 100 parts by weight of resin. , 10 parts by weight and 2 parts by weight, respectively

(Part name manufactured by Kansai Paint@, epoxy resin emulsion paint) was applied with a roller at a rate of 200 g/rrr and allowed to dry for one week.

Next, a commercially available laundry glue was applied to the coating film, and then imitation paper was attached. Then, a peel test of the imitation paper was conducted depending on the number of hours and days after pasting. The results are shown in Table 1.

Example 4 "Gloster Sealer" (part name manufactured by Kansai Paint ■, acrylic resin emulsion-based undercoat paint) was applied to the concrete mortar surface at a rate of about 100 g/rd and dried for 4 hours. Next, Gloster (part name manufactured by Kansai Paint@, acrylic resin emulsion-based topcoat paint) containing 20 parts by weight of liquid paraffin per 100 parts by weight of resin was applied with a roller at a rate of 180 to 200 g/bo for one week.
