Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a novel anti-sticking coating composition and a coated article. In particular, the present invention relates to a sticker-preventing coating composition and a coated article for forming a surface with a high sticker-preventing effect by painting or attaching a coated article to buildings such as telephone poles, fences, and walls.

[Conventional technology]

Conventional pasting prevention paints include paints containing silicone oil and/or wax (Japanese Unexamined Patent Publication No. 1986-1
No. 06864), silicone rubber beads added (
JP-A-62-25180) and those containing polyorganosiloxane (JP-A-61-159463, JP-A-61-151044) are known. These sticker-preventing paints incorporate fluororesin, silicone resin, and silicone compounds into the paint to impart non-adhesive and slippery properties to the coating, reducing the adhesiveness of the stickers. .

However, these anti-sticking paints have the disadvantage of poor adhesion to materials, and their anti-sticking effects decrease over time.

In addition, when preparing paints, if they are mixed with other paints, repelling or bubbling may occur when the mixed paints are applied, which is a constraint on manufacturing.

[Problem to be solved by the invention]

An object of the present invention is to provide a novel sticker-preventing coating composition and coated product that can form a coating film that has a small contact area with the sticker and has the property that the sticker does not stick to the composition.

[Means for Solving the Problem] The pasting prevention coating composition of the present invention comprises (A) 40 to 95 parts by weight of a coating resin having a hydroxyl group, and (B) the following general formula (1).
) 5 to 60 parts by weight of a low-nuclear melamine resin containing at least 40% by weight of hexakisalkoxymethylmelamine (wherein R represents an alkyl group, of which 3 or more are methyl groups, ), and (C) a sulfonic acid compound blocked with an amine compound having a secondary or (and) tertiary amino group with a boiling point of 50 to 300°C, (A) A pasting prevention coating composition is characterized in that it contains 0.1 to 5 parts by weight of sulfonic acid based on 100 parts by weight of the total solid content of (B).

Further, the anti-sticking coated article of the present invention is a coated article in which the above-mentioned anti-sticking coating composition is applied onto a base material to form an anti-sticking coating film.

The substrate to be coated with the anti-sticking coating composition of the present invention may be any material as long as it can withstand the coating curing conditions, and its shape etc. are not limited.

Examples of such base materials include wood base materials such as wood, plywood, and particle board; gypsum base materials such as gypsum board and gypsum slag board; Fiber cement 1~material;
GRC and concrete 1 ~ materials; iron, aluminum,
Examples include metal materials such as copper, stainless steel, titanium, and zinc; paper materials; stone materials; glass materials; plastic materials; tile materials; and composite materials of each of the above base materials. These base materials can be of any shape, such as a flat plate, a curved plate, or a molded one, as long as they are the object of pasting. It is also possible to coat these substrates with a normal undercoat, intermediate coat, or topcoat and then apply the paper-sticking prevention coating composition of the present invention.

The coating resin having a hydroxyl group as the component (A) used in the sticker-preventing coating composition of the present invention is as follows: 1. Any resin having a hydroxyl group that is commonly used in coatings can be used without any restriction.

Further, as the fluororesin having a hydroxyl group, for example, Lumiflon (trademark) manufactured by Asahi Glass Co., Ltd. and Cefral Coat (trademark) manufactured by Central Glass Co., Ltd. can be used.

These hydroxyl group-containing resins can be used alone or in combination of two or more. The blending amount of these is 40 to 95 parts by weight, preferably 60 to 90 parts by weight as resin content (solid content).

If the amount used is less than 40 parts by weight, the reaction with the low-nuclear melamine resin will be insufficient, and coating film performance such as processability and corrosion resistance will deteriorate. If the amount exceeds 95 parts by weight, the amount of low-nuclear melamine resin will be too small to cause sufficient crosslinking reaction, resulting in poor coating performance such as workability and corrosion resistance.

Such low-nuclear melamine resins contain a large amount of alkyl groups per unit weight compared to polynuclear (high molecular weight) melamine resins commonly used in paints, and this high functional group content is used in anti-sticking paints. This is a necessary requirement.

3 of the alkyl groups that are functional groups in low-nuclear melamine resin
When the main component is HAMM in which at least 3 are methyl groups and less than 3 are alkyl groups having 2 to 5 carbon atoms, it has an uneven and wrinkled surface due to the crosslinking reaction between methoxyl groups and hydroxyl groups in the resin containing hydroxyl groups. An anti-pasting coating is formed. It is not preferable that three or more of the alkyl groups have 2 to 5 carbon atoms because these functional groups have lower reactivity with the hydroxyl group in the resin having a hydroxyl group than a methoxyl group.

Examples of such low-nuclear melamine resins include Cymel 300.301.303.11 manufactured by Mitsui Toatsu Chemical Co., Ltd.

These can be used alone or in combination.

The amount of low-nuclear melamine resin used is 5 to 60% as solid content.
Parts by weight, preferably 10 to 40 parts by weight.

If it is less than 5 parts by weight, a sufficiently cured coating film will not be obtained, and corrosion resistance,
Coating film performance such as weather resistance deteriorates. Moreover, if it exceeds 60 parts by weight, the coating film will be brittle and poor in coating film performance such as corrosion resistance and weather resistance.

The sulfonic acid compound (hereinafter referred to as blocked acid catalyst) blocked with an amine compound having a secondary or (and) tertiary amino group as component (C) used in the present invention is used as a curing catalyst, and is used as a curing catalyst. In addition to methanesulfonic acid, aromatic sulfonic acids such as para-toluenesulfonic acid, dodecylbenzenesulfonic acid, dinonylnaphthalenesulfonic acid, dinonylnaphthalene disulfonic acid, and the following structural formulas [11) to [■], R□-8o3H・=(II) ○ II II R, -C-○-CH, CH25o3H...[■]^ R10-(CH,), ~, S O3H...[■]R□

It is blocked with an amine compound having a primary or (and) a tertiary amino group. Other acid catalysts include organic carboxylic acids such as maleic acid and phthalic acid, carboxylic acids inherent in polyols, and phosphate catalysts, but all of these have weak effects as acid catalysts and are less likely to be used as low-nucleate compounds as mentioned above. In combination with melamine resin, the crosslinking reaction promotion effect is weak.

Examples of amine compounds having a secondary amino group with a boiling point of 50 to 300°C that serve as blocking agents include diethylamine, dipropylamine, diisopropylamine, dibutylamine, diisobutylamine, di-2-ethylhexylamine, di-secondary butylamine, and diallylamine. , N-methylhexylamine, 3-pipecoline, 4

The aliphatic sulfonic acids represented by the above structural formulas (11) to [■] can be obtained by converting an aliphatic sulfonic acid salt such as a sodium salt or potassium salt of a sulfonic acid into a free acid by desodiumization or depotassiumization. good.

The blocked acid catalyst is produced by charging an amine compound having a secondary or (and) tertiary amino group and a sulfonic acid into a container, and stirring the mixture at 20 to 30°C for 10 to 20 minutes.

The molar ratio of amine/sulfonic acid is from 0.5 to 7, preferably from 1 to 5, and only in this case an anti-pasting coating having an uneven, wrinkled surface is formed. When the amine/sulfonic acid molar ratio is less than 0.5, there is a large amount of unblocked sulfonic acid, resulting in poor storage stability of the paint. On the other hand, if the molar ratio exceeds 7, no improvement is observed due to the addition of the blocking agent, the curing reaction slows down, and the coating hardness, corrosion resistance, weather resistance, etc. of the resulting coating film decreases.

The amount of the blocked acid catalyst to be used is 0.1 to 5 parts by weight, preferably 0.1 to 5 parts by weight as sulfonic acid, based on 100 parts by weight of the total solid content consisting of the resin having a hydroxyl group and the low-nuclear melamine resin.
It is 2 to 4 parts by weight. If the amount is less than 0.1 part by weight, the catalytic effect during baking will be insufficient, resulting in poor corrosion resistance, weather resistance, etc. of the coating film.

Further, it is not necessary to use more than 5 parts by weight, and even if more than this is used, coating film performance such as corrosion resistance and weather resistance will only deteriorate.

The pasting prevention coating composition of the present invention has the above-mentioned (
It contains components A) to (C). Above (A)~
The anti-pasting coating composition containing component (C) may be used as a clear coating as it is, or may be used as a clear coating or
C) Ingredients include dyes such as oil-soluble dyes and dispersible dyes; organic pigments such as azo pigments, phthalocyanine pigments, lake pigments, quinacridone pigments, and dioxazine pigments; inorganic pigments such as titanium oxide, iron oxide, and carbon black; aluminum, copper Metal powders such as talc, barium sulfate, silica, barium carbonate, alumina white, clay, calcium silicate,
Adding extender pigments such as precipitated magnesium carbonate,
It can also be used as color clear paint or enamel paint.

In addition, the anti-sticking coating composition of the present invention may contain wax-based slipping agents such as polyethylene, silicone, and fluororesin, antifoaming agents, leveling agents, pigment dispersants, ultraviolet absorbers, light stabilizers, heat stabilizers, and the like. Agents can be added as necessary.

The above-mentioned sticker-preventing paint composition is diluted with a solvent such as Kijiroll if necessary to an appropriate coating viscosity, and applied to a roll coater, flow coater, roll flow coater, bar coater, etc.
Apply the coating to the object using a coating machine such as a spray gun or an electrostatic spray coating machine at 100 to 400°C, preferably 1.
．． By baking at a temperature of 20 to 300°C for 10 seconds to 60 minutes, preferably 30 seconds to 30 minutes, to a dry coating thickness of 10 to 100 μm, preferably 15 to 80 μm,
A coated article having an anti-sticking coating is obtained in which the dried coating forms a textured, wrinkled surface which reduces the contact area of the sticker and thereby prevents the sticking of the sticker. If the dry coating thickness of the anti-sticking coating composition is less than 10 μm, a coating film with a shrinking surface cannot be obtained, and if it exceeds 100 μm, foaming or the like occurs in the coating film, resulting in poor coating appearance.

The sticker-preventing paint composition of the present invention may be applied directly or indirectly to buildings such as telephone poles, fences, and walls to form a sticker-preventing coating, or may be applied to a base material to prevent stickers. A sticker-preventing coated article with a coating film formed thereon may be attached to the above-mentioned buildings, etc.

Even if posters or other posters are affixed to the anti-sticking painted object formed in this way, the contact area of the coating film formed on the painted object with the affixing paper is small, so the adhesion of the adhesive laminate is particularly poor.
Highly effective in preventing stickers.

1, Eng. □.

As mentioned above, the sticker-preventing paint composition of the present invention uses a resin with good adhesion to the substrate to form a coating film with a small contact area with the sticker, so it has good adhesion to the substrate. Moreover, unlike conventional anti-pasting paints that use fluororesin, silicone resin, and silicone compounds oriented on the surface to provide non-adhesiveness and slipperiness to the surface of the coating, the wrinkles that form on the coating are caused by the unevenness of the surface. Because it uses a small contact area, the sticker prevention effect continues over time.

In addition, the paint has excellent storage stability, and if mixed with other paints, it will not cause repelling or bumps when painted, and has excellent coating hardness, corrosion resistance, and weather resistance. A coating film can be obtained.
