Description

Wall paper construction method using anti-dyeing coating composition {WALL PAPERING METHOD USING TRANSFER INHIBITOR COMPOSITION}

The present invention relates to a wallpaper construction method using an anti-transfer coating liquid composition that prevents migration from occurring over time when wallpaper is applied to gypsum board among interior finishing materials of various buildings, and includes a water-soluble acrylic emulsion, ethanol, and meshel. Transfer dye that can reduce unnecessary construction time and construction costs in advance due to dissatisfaction and defects caused by the tenant's construction after moving in through the anti-transfer coating liquid containing a loss (methyl cellulose) thickener. It relates to a wallpaper construction method using an anti-coating liquid composition.

First, the dyeing phenomenon refers to the phenomenon that the sublimation dye (colored paper) contained in the base paper of the gypsum board melts and spots such as red, yellow, and blue appear on the surface of the wallpaper.

This dyeing phenomenon is a phenomenon that occurs mainly in silk wallpaper (PVC) rather than paper wallpaper.

The cause is that the sublimation dye is dissolved in the plasticizer contained in the wallpaper, or the sublimation dye is dissolved by PVA (Polyvinyl alcohol) and PVAc (Polyvinyl acetate) contained in the bond and binder in the paper paste to increase the adhesion strength during wallpaper construction. Or

As gypsum board mixed with sublimation transfer paper is used on the gypsum board base, the sublimation dye contained in the gypsum board base melts after time elapses due to the rise of lamps, home appliances, and air temperature and is struck down by gravity, so that it is transferred to the wallpaper surface. Will occur.

As such a prior art, there is registered patent No. 10-0467775 "Staining-resistant wallpaper and its manufacturing method",

The prior art includes a laminated structure of a first coating layer or a second coating layer on the base layer of the wallpaper surface, and the composition of the coating layer surface is applied to the surface of a coating solution consisting of polyurethane or urethane-acrylate composition to It proposes a technology that prevents contamination from water.

However, in the prior art, by forming a polyurethane layer or urethane-acrylate on the surface of the wallpaper, the sublimation dye (colored paper) contained in the base paper of the constructed gypsum board melts and is struck down by the gravity of the earth, so that the polyurethane layer or Due to the urethane-acrylate layer, there is a problem that the spots are spread out more due to the coating layer, and because there is a coating layer, there is no place for the dissolved dye to escape after injection of acetone, so that removal is impossible.

Another prior art is Patent Publication No. 10-2016-0070081 "a coating composition having improved liquid stain repellency and a manufacturing method thereof",

The coating composition in the prior art is polymer particles of i) 12% to 80% per dry weight based on the total dry weight of the coating composition, per dry weight based on the total dry weight of the polymer particles, polymerization As a unit, from 3% to 70% vinyl acetate; 2% to 65% styrene; And 20% to 55% of the (meth)acrylate monomer; ii) 0.1% to 6% wax; And iii) 14% to 55% pigment. It also proposes a technique for preparing the coating composition.

However, it is effective in preventing contaminants and repellency on the surface of wallpaper, but sublimation dyes (colored paper) contained in gypsum boards, plasticizers contained in wallpaper, and bonded to coarse glue to increase adhesion strength when constructing wallpaper. And there is a problem in that it is impossible to prevent the migration phenomenon caused by dissolution due to the PVA and PVAc components contained in the reinforcing agent to which the binder is added.

Therefore, the present invention was devised to solve the above problem,

It is intended to provide a wallpaper construction method using an anti-migration coating composition that can prevent migration caused by dissolving sublimation dyes with PVA and PVAc components of sublimation dyes and plasticizers contained in wallpaper, reinforcing agents used in paper paste and bonds. To do.

Specifically, a coating layer is formed on the gypsum board or wallpaper or both through a dyeing prevention coating solution containing a water-soluble acrylic emulsion, and the background paste used does not contain PVA and PVAc components to prevent migration to prevent migration. Another object is to provide a wallpaper construction method using a coating liquid composition.

Wallpaper construction method using the dyeing prevention coating liquid composition according to the present invention

Forming a coating layer by applying an anti-transfer coating solution to wallpaper or gypsum board or both,

It comprises a step of curing the formed coating layer and a step of laminating the wallpaper and the gypsum board using an adhesive member.

First, the anti-salt coating liquid composition according to the present invention is characterized in that it comprises a water-soluble acrylic emulsion, ethanol, and mecellose (methyl cellulose) thickener.

More specifically, the water-soluble acrylic emulsion is Methyl acrylate, Ethyl acrylate, Isopropyl acrylate, n-Butyl acrylate, 2-Ethylhexyl acrylate, Methyl methacrylate, Ethyl methacrylate, n-Butyl methacrylate, iso-Butyl methacrylate, n-Hexyl methacrylate, Lauryl Consisting of mixing one or two or more mixtures selected from the group consisting of methacrylate, methacrylic acid, 2-Hydroxyethyl methaacrylate, and Hydroxypropyl methacrylate and purified water,

More preferably, n-Butyl Acrylate Monomer 4 wt%, Methyl Methacrylate Monomer 18 wt%, 2-Ethyl hexyl acrylate 18 wt%, Methacrylate 2 wt%, 2-Hydroxyethyl Methacrylate 2 wt%, Anionic surfactant 1 wt%, It is made by including 55% by weight of purified water, and the ethanol is preferably composed of 5 to 10 parts by weight, and 2 to 10 parts by weight of mecellose (methyl cellulose) thickener when the total weight of the total anti-transfection coating solution is 100 parts by weight,

More preferably, when the total weight of the dyeing prevention coating solution is 100 parts by weight, it is characterized in that it comprises 7 parts by weight of ethanol and 3 parts by weight of a thickener of mecellose (methylcellulose).

In addition, as the ethanol does not dissolve the sublimation dye, it is preferable to improve the drying speed to have the effect of shortening the drying time of the coating layer (C),

The mecellose (methyl cellulose) thickener is also preferably made of a thickener that does not dissolve the sublimation dye.

Here, the thickener refers to a solution used for pharmaceuticals, adhesives, cement, latex, paints, cosmetics, etc. by increasing the viscosity.

In particular, the present invention uses a mecellose (methyl cellulose) thickener,

First of all, Mecellose is made from cellulose obtained from wood and cotton, and cellulose refers to an insoluble natural polymer having 30 to 65% crystallinity due to hydrogen bonding between molecules. Cellulose, which is insoluble in water, is made of a water-soluble polymer called Cellulose ether, Mecellose, and Hecellose through etherification, and mecellose and hecellose are nonionic. As a water-soluble polymer, it is used as a thickener, moisturizer, lubricant, stabilizer, etc. in various fields such as construction, cement extrusion, ceramic extrusion, polymer polymerization, paint, detergent and medicine, and household goods.

As the physical properties of the mecellose,

1. Solubility

It dissolves easily in cold water, but does not dissolve in hot water, only dispersion.

2. Nonionic

It has excellent compatibility with various ionic/nonionic additives in the aqueous solution state, providing stable dissolution properties.

3. PH stability

It maintains a very stable viscosity in the range of pH 3.0 to 11.0, and this solubility can be affected by pH conditions (acid.base).

4. Organic solvent solubility

Some specifications are also soluble in polar organic solvents or mixtures of water and organic solvents.

5. Suspension stability

It increases the stability of the suspension in the solution.

7. Surface activity

It shows the properties of a surfactant having both hydrophilicity and hydrophobicity, and can be used in areas requiring a protective colloid function or an emulsification function.

8. Gelling characteristics

Mecellose is well soluble in cold water through a hydration reaction with water. In hot water, it is only dispersed by gelation, and some of the highly substituted standards (PMA, PMB, PMH standards) increase in hydrophobicity. Soluble in organic solvents.

In addition, hecellose has similar properties to mecellose, but does not gel even in hot water.

Therefore, due to the above components, the dyeing prevention coating solution according to the present invention has the characteristics of excellent water resistance, adhesion, dryness, flexibility, weather resistance, flowability, and workability.

In addition, this dyeing prevention coating solution is preferably applied to wallpaper or gypsum board and then cured to form a coating layer.

Along with this, it is possible to mix and use the adhesive member, and in this case, a coating layer may not be formed, but it is more preferable to form a coating layer to improve adhesion due to the same type of components.

In the present specification, as a member containing an adhesive liquid component for constructing the adhesive member wallpaper, it is preferably made of a viscous adhesive liquid, and more preferably made of a mixture of starch, water, etc., and adhesion to the total weight It is preferable that the member and the coating solution be made in a ratio of 3:7 to 7:3,

More preferably, it is preferable to mix the adhesive member and the coating solution at a weight ratio of 1:1.

It is preferable that the adhesive member in the present invention use an eco-friendly material to prevent chemical substances from coming out of the wallpaper,

The adhesive member is characterized in that it is produced after aging by mixing rice and water.

More specifically, rice and water are mixed in a weight ratio of about 1:2, soaked, exposed to the atmosphere, and aged at room temperature for about 6 days. At this time, starch generated from rice is discharged together with water. After repeating this process about 10 times, the solid material obtained by naturally drying the obtained precipitate is mixed with water in a weight ratio of about 1:1, and the viscosity is gradually stirred for 5-10 minutes at a temperature of 60-70 degrees Celsius. To manufacture an improved adhesive member.

In addition, the adhesive member may be used by further mixing the Sancho extract so as to have excellent antibacterial and antifungal properties.
