Abstract

PURPOSE:To make a masking material reusable and to make the mounting and detachment thereof easy, by attracting a magnetic material cut into a required shape and having elasticity and flexibility to a magnetically permeable material as the masking material before performing painting. CONSTITUTION:A magnetic material having elasticity and flexibility is cut into a required shape. This cut magnetic material is attracted to a magnetically permeable material as a masking material to apply paint to said magnetically permeable material. The magnetic material is pref. prepared by containing a magnetic material such as a magnet in a synthetic resin such as a silicone resin or acrylic resin having elasticity and flexibility and has a sheet shape having a thickness of 0.5-3mm. In the cutting of the magnetic material into the required shape, a cutter can be employed and the cross-sectional shape of the cut part pref. has a trapezoidal from having the attracted part as a long side in order to improve painting finish.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a coating method for obtaining coated products for industrial, industrial and domestic use.

[Background technology]

Conventionally, masking materials have been made by cutting paper or plastic sheets with adhesive on one side into the desired shape, pasting them on the desired positions of the object to be painted, and then painting. It is expensive because it cannot be used, it requires skill to apply because it is a thin sheet, it takes time to remove it after painting, and depending on the solvent of the paint, adhesive may remain and cleaning is required. There were drawbacks such as becoming

[Purpose of the invention]

An object of the present invention is to provide a coating method that allows the masking material to be reused, is easy to attach and detach in a short time, and allows double-sided masking coating.

[Disclosure of the invention]

The present invention is capable of achieving the above object because it is a coating method characterized by adsorbing an elastic and flexible magnetic material cut into a desired shape onto a magnetically permeable material to form a masking material before painting. The present invention will now be described in detail.

Magnetic materials used in the present invention include elastic and flexible synthetic resins such as silicone resin, acrylic resin, vinyl resin, polyurethane resin, polyethylene resin, and fluororesin, natural rubber, isoprene rubber, styrene rubber, and butyl rubber. , Butadiene rubber, ethylene propylene rubber, nitrile rubber, chloroprene rubber, Heibalon, urethane rubber, polysulfide rubber, silicone rubber, fluororubber, acrylic rubber, and other rubbers alone, modified products, and mixtures containing magnetic materials such as magnets. It is preferable that the sheet be in the form of a sheet with a thickness of 0.5 to 3H because it is easy to handle and convenient. Cutting into the desired shape can be done by cutting with a cutter, cutting by punching, etc. The cutting method is not particularly limited, but it is important that the cross-sectional shape of the cut part is trapezoidal with the long side being the suction part, so that the paint finish is not affected. This is a good thing.

The magnetically permeable material is not particularly limited as long as it can be coated with a magnetic material such as iron.

The present invention will be explained below based on examples.

Example After cleaning the surface of the iron plate, a 2WM thick elastic and flexible magnetic sheet cut into the desired shape was adsorbed with Chirei Magnet Co., Ltd. (product name: 11ES-7P) at the desired position to serve as a masking material. After spraying an inorganic paint (manufactured by Matsushita Electric Works Co., Ltd., product name CM2110-1), pre-drying it at a glossy ~■°C to make it tack-free, removing the masking material, and baking it at 160°C for an additional time to create a painted product. I got it.

Comparative example After cleaning the iron plate surface, the thickness was cut into the required shape Q21R'
Paste the single-sided adhesive paper of ff to the required position to use as a masking material, then spray apply the same inorganic paint as in the example, pre-dry it with ``C'' and remove the masking material. A coated product was obtained by additional baking at 160″C.

〔Effect of the invention〕

As is clear from Table 1, the coating conditions of Examples and Conventional Examples show that the performance of the coating of the present invention was good, confirming the superiority of the coating of the present invention.

Note to Table 1: Look at the presence or absence of a clear boundary between the masking area and the painted area.
