Definitions
- the present invention relates to an easy-to-peel coating composition, and more particularly, to an easy-to-peel coating composition that can be restored to its original state by easily peeling the coating layer when changing color and design preferences or wanting to use it again as an original product.
- paint is a fluid material that is widely applied to the surface of an object to form a thin film layer and dries and hardens over time to protect the surface of the object as well as increase the aesthetics.
- such paint is applied to various structures such as buildings to make the appearance of the structure beautiful, and is often used to improve durability by preventing damage such as corrosion.
- paints mainly used for the protection of structures such as buildings there are oil-based paints, enamel paints, and water-based paints. These paints have the effect of not only protecting buildings and materials (materials), but also increasing aesthetics and improving insulation and heat resistance.
- Paints such as general paints are being developed for the main purpose of improving adhesion to materials to improve durability, and have a characteristic that it is not easy to peel off after drying/curing after application to a work piece.
- Paints such as general paints are being developed for the main purpose of improving adhesion to materials to improve durability, and have a characteristic that it is not easy to peel off after drying/curing after application to a work piece.
- a material such as paper wallpaper
- the peeling cannot be done at all or the paper is torn when peeled forcibly.
- the object of the present invention is to maximize the effect of restoring the original state because it is easy to peel off the material on which the paint is applied, and at the same time, it is designed as a water-based type and developed for use in indoor interiors and in contact with the human body.
- An object of the present invention is to provide an easy-to-peel coating composition having excellent protection and durability.
- a paint composition that can be easily peeled off from an object according to the present invention includes 30 to 80 parts by weight of a PVB (polyvinyl butyral) resin; 1 to 5 parts by weight of an additive containing an antifoaming agent; and a water-soluble solvent containing water as the remainder.
- a PVB polyvinyl butyral
- the molecular weight of the PVB resin may be 100,000 to 210,000 g/mole, and the PVB resin may have a particle size of 170 to 240 ⁇ m.
- the coating composition may further include an additional component including latex, acrylic copolymer, polyvinyl acetate, urethane or polyvinyl alcohol, wherein the weight ratio of the PVB resin to the additional component is 9 to 12: 1 day.
- an additional component including latex, acrylic copolymer, polyvinyl acetate, urethane or polyvinyl alcohol, wherein the weight ratio of the PVB resin to the additional component is 9 to 12: 1 day.
- the paint composition may include any one or more of a releasability additive and an inorganic material.
- the releasability additive is selected from the group consisting of silicone oil, silicone polymer, silicone emulsion, modified silicone oil or polymer, siloxane and modified siloxane, silicone rubber, wax-type additive, surfactant, oil, and silane 1 to 20 It may contain parts by weight.
- the inorganic material may include 5 to 40 parts by weight of at least one selected from the group consisting of SiO 2 , CaCO 3 , BaSO 4 , Talc, Al(OH) 3 , Al 2 O 3 and TiO 2 .
- the aqueous solvent may further include any one or more of alcohols, cellosols, and carbitols.
- the object may be made of paper, wood, or glass.
- the present invention relates to an easy-to-peel paint composition, and it can be used as a functional paint with excellent durability while maximizing the effect of restoring the original state and protecting the material because it is easily peeled off from the material to which the paint is applied.
- the easy-to-peel paint composition of the present invention is designed to be water-based and eco-friendly, so it can be safely used even when in contact with the human body, so it can be applied to indoor interiors. In this case, there is an advantage regardless of location and use.
- the easily peelable paint of the present invention is applied and the dried/cured coating film can be peeled off, and the peeled coating film is dissolved in alcohol and can be recycled.
- the heat insulating material is mixed or dispersed in the easy-to-peel paint of the present invention and applied to an external window, it is possible to obtain cold protection and thermal insulation effects.
- FIG. 1 is a photograph comparing the state in which a paint containing PVB resin alone (A ⁇ ), a paint containing a releasability additive (B ⁇ ), and a paint containing an inorganic material (C ⁇ ) are applied to paper.
- FIG 3 shows photographs showing before and after peeling from glass according to the content ratio of PVB and latex.
- FIG 4 shows photographs showing before and after peeling from silk (PVC) wallpaper according to the content ratio of PVB and latex.
- the present invention is an easily peelable paint composition
- a polyvinyl butyral (PVB) resin comprising a polyvinyl butyral (PVB) resin, an additive including an antifoaming agent, and water, and may further include a releasability additive or an inorganic material.
- the easy-to-peel paint composition protects the applied material and has excellent durability compared to the general paint that can be peeled off, and it is easy to peel off even from paper wallpaper, so it maximizes the restoration effect of the material. There is an advantage that it can be used safely regardless of place and purpose as it is used for indoor interiors.
- the PVB (polyvinyl butyral) resin is dissolved in the water and painted on the surface of the material, and serves to protect the surface after the solvent is dried. It is desirable to have characteristics.
- the PVB (polyvinyl butyral) resin is a resin having excellent flexibility, tensile strength, and toughness in the form of water dispersion, and has the advantage of enabling easy peeling of the easily peelable paint composition from the material.
- the PVB (PolyVinyl Butyral) resin may be prepared by a condensation reaction of PVA and n-butyraldehyde.
- the PVB resin may be of an aqueous or emulsion type, and when the solvent is dried after painting on the surface of the material, it serves to protect the surface of the material.
- the PVB resin is a resin excellent in flexibility, tensile strength and toughness, and it is possible to easily peel the peelable paint composition from the material.
- the structure of the PVB resin may include a butyral group, an acetyl group, and a hydroxyl group represented by Chemical Formula 1 below as repeating units.
- the molecular weight of the PVB resin is 100,000 to 210,000 g/mole, it is excellent in terms of peelability and storage stability, and when the PVB resin has a particle size of 170 to 240 ⁇ m, peelability and storage stability are further improved has the effect of being

- a material such as wood or glass, including paper wallpaper.
- a material such as paper, which has many pores (porous) and the internal cohesion between the material is weak, so that interlayer separation may occur, it is difficult to peel the coating layer from the paper because of its high adhesion with the paint.
- the easy-to-peel paint composition may further include a pigment to identify the painted portion.
- the pigment include extender pigments, colored pigments, and mixed pigments thereof.
- the easily peelable paint composition may contain 5 to 30 parts by weight of the pigment, preferably 5 to 20 parts by weight.
