Description

Eco-Friendly FUNCTIONAL COATING COMPOSITIONS FOR FINISHING FLOORS AND WALLS OF CONCRETE STRUCTURES USING NATURAL MINERALS}

The present invention does not emit harmful substances such as formaldehyde or volatile organic compounds (VOCs), radiates far-infrared rays and anions, which are helpful for health promotion, and has deodorizing ability, antibacterial properties, chemical resistance, It relates to an eco-friendly functional paint composition for finishing concrete structure floors and walls using natural minerals with improved weather resistance, waterproofness, insulation and flame retardancy.

Paints are roughly classified into water-based paints and oil-based paints depending on the vehicle used as a product that protects the object by applying it on the surface of the object to form a dried coating layer and makes the appearance beautiful.

Water-based paints use water instead of organic solvents, so the emission of volatile organic compounds is low, and since it is economical and easy to handle, emulsion paints mainly used for building walls are typical. Oil-based paints use organic solvents to reduce the emission of volatile organic compounds. There are many, and oil-based enamel used for woodworking is typical. However, due to various reasons, the quality of water-based paints has not yet reached that of oil-based paints, and recently, in order to lower the amount of volatile organic compounds in oil-based paints, the development of water-soluble paints, which is an intermediate product between water-based paints and oil-based paints, has been actively progressed.

In the conventional finishing treatment of floors and walls of concrete structures, functional members such as a waterproofing agent, paint, wood, etc., or functional members such as insulation were installed and then treated with a finishing material to give functionality.

However, finishing materials such as paints, wallpaper, flooring, plywood, and insulation are experiencing many difficulties with symptoms such as sick house syndrome, which is caused by harmful substances such as formaldehyde and volatile organic compounds.

Therefore, it is possible to fundamentally block formaldehyde and volatile organic compounds in the lifestyle of modern people who improve the living environment and pursue the quality of life, and radiate far-infrared rays and negative ions, which are helpful for health promotion, and deodorizing ability, antibacterial, etc. Eco-friendly finishing materials with the same function are required.

The acrylic copolymer is an acrylic monomer such as MMA (methyl methacrylate), MA (methyl acrylate), and 2-HEMA (hydroxy ethyl methacrylate), and a silane having an unsaturated group, an alkoxy group, or a hydroxy group. It is preferable to use a water-soluble acrylic copolymer obtained by copolymerizing the compound.

The silica aerogel has an insulating effect as the air filled with silicon dioxide having extremely high porosity is sealed, and it is difficult to disperse when 2 parts by weight or more is added.

The amethyst emits 90% or more of far-infrared rays, and is known to promote deodorization, suppression of harmful bacteria and metabolism, and if it is added in an amount of 5 parts by weight or more, the amount of far-infrared radiation is improved, but it causes sedimentation in the paint.

In addition, the preferred dosage is 5 to 20 parts by weight, and flame retardancy and heat resistance are improved when excessively added, but there is difficulty in adhesion or dispersion.

The dispersant is preferably added with at least one of dispersants such as methoxyalkyloxyacetic acid, sodium polyacrylate, maleic anhydride, sodium alkylnaphthalenesulfonic acid, and alkylbenzenesulfonate.

The thickener is added to prevent sedimentation of the functional raw material and maintain an appropriate viscosity. It is preferable to add at least one of inorganic thickeners such as acrylic, urethane, and clay.

In the present invention, the stabilizer is applied to concrete, and an alkylamine or alkylamide is added to maintain stability with a soluble substance generated during the hydration reaction of concrete, and a sunscreen agent is used to prevent discoloration or aging. Can be put in.

The input sunscreen is a physical sunscreen such as zinc oxide and titanium dioxide, or chemicals such as oxybenzone, abovenzone, and ethylhexyl methoxycinnamate. It is preferable to add at least one of the sunscreen agents, and the total amount of the stabilizer is preferably 3 to 6 parts by weight.
