The present invention relates to a high-performance waterproof coating composition having a heat shielding and heat insulating performance that can replace the conventional urethane waterproofing method and a method of constructing a heat insulating and heat shielding structure for buildings using the same.

In general, in a new building or an old building, a heat insulating material such as styrofoam is attached to the outer wall of the building to form a heat insulating wall, and an outer heat insulating panel having a finishing plate made of artificial stone or natural stone is attached to the outside of the heat insulating material. Continuously attached to the left and right, to enhance the appearance of the building while improving the insulation, heat insulation and sound insulation.

However, in order to attach the finishing plate to the outside of the heat insulating material, by applying an adhesive or an adhesive mortar on the outer surface of the heat insulating material and then attaching the finishing plate to the wall surface of the building, the conventional exterior heat insulation panel constructed as described above Since adhesives and adhesive mortars do not have insulation and heat shielding effects, and finish plates are also known to have little insulation and heat shielding effects, the thermal insulation effect is not so large in proportion to the construction of a relatively complicated and expensive exterior insulation panel. There has been a problem of low efficiency.

On the other hand, urethane waterproofing paints, which have been widely used as exterior paints for buildings, require problems such as blistering and lifting of the coating film, and the effect of blocking and blocking heat from external heat is not high. to be.

Accordingly, the inventors of the present invention have excellent heat shielding effect and thermal insulation effect compared to the existing urethane waterproofing method, and have high resistance to compression and corrosion of concrete and cement buildings, and excellent resistance to chemical components such as salt, oil, etc. The functional waterproof coating composition was developed, and the construction method of the thermal insulation and thermal insulation structure for buildings was used.

Accordingly, an object of the present invention is to provide excellent heat resistance and heat insulation effect for the purpose of extending the life of a building as well as to save energy, and to improve the compressive strength of the building such as concrete or cement and to prevent corrosion, and to have excellent resistance to chemical components such as salt and oil. It is to provide a highly functional waterproof coating composition having weather resistance.

In addition, another object of the present invention is to provide a method for constructing a heat insulating and heat shield structure that can be applied to a building using the above-described high-performance coating composition.

In addition, in order to achieve another object, the present invention provides a method for constructing a heat insulating and heat shield structure for buildings, characterized in that using the coating composition.

Hereinafter, with reference to the accompanying drawings, a high functional waterproof coating composition having a thermal insulation and heat insulating performance according to the present invention and a construction method using the same will be described in detail.

At this time, if there is no other definition in the technical terms and scientific terms used, it has a meaning commonly understood by those of ordinary skill in the art.

In addition, repeated description of the same technical configuration and operation as in the prior art will be omitted.

Insulation in the present invention means to prevent the conduction of heat (말) refers to the suppression of heat transfer to the inside of the building, the heat shield (遮 熱) is visible light or infrared rays that act as a heat It means to reduce or prevent the heat flowing in or out by reflecting the light, which means preventing the heat flowing in from the outside of the building or suppressing the leakage of heat generated from the inside.

 The present invention by developing a high-performance paint, such as heat shielding and heat insulation performance that can be used on the building interior / exterior materials surface, when applied to the outside, the concrete compressive strength enhancement and corrosion protection and waterproof function is the basic and high energy in sunlight Reflects infrared rays to protect internal room temperature from external climate and temperature, minimizing energy loss due to external environmental changes, and reflecting radiant heat generated from internal heating element when applied internally, dramatically reducing cooling and heating costs by maximizing energy efficiency It is possible to provide an effect that can effectively improve the durability of the building.

At this time, in the coating composition according to the present invention, the acrylic emulsion resin or the styrene-butadiene copolymer emulsion resin uses 15 to 46 parts by weight as a substrate for forming a coating film, which is less than 15 parts by weight, which reduces the adhesion of the coating film. This may cause problems of falling due to self-weight or external force and a problem of lowering the elasticity of the waterproofing agent, and when used in excess of 46 parts by weight, the elasticity and adhesion are insignificant while the viscosity of the paint is increased, thereby reducing workability. .

In addition, in the present invention, the film-forming substrate is a styrene and butadiene copolymer emulsion having excellent resistance to high elasticity, acrylic emulsion resin and concrete and mortar to increase the compressive strength, corrosion resistance, and chemical components such as salt and oil.

Alumino silicate provides heat shielding, thermal insulation effect as well as noise prevention function in the coating composition of the present invention. In order to maximize the above-mentioned effect, it is used in the form of fine microscopic hollow powder (Ceramic Microscopic Hollow Spheres). desirable. At this time, if the use of less than 5 parts by weight of the noise protection, heat shielding, heat insulation function is sharply reduced and the use of more than 20 parts by weight, the above-mentioned effect is not greatly increased, while the expensive ceramic hollow powder is used excessively Since manufacturing cost greatly increases accordingly, it is preferable to use it within the use range mentioned above.

In the present invention, calcium carbonate, talc and titanium dioxide (TiO ₂ ) is used for the coating hiding power by using as a extender pigment, calcium carbonate is 15 to 35 parts by weight, talc is 5 to 10 parts by weight, and titanium dioxide is 2 ~ It is preferable to use 7 parts by weight. If the mixing ratio between each component is less than the above-mentioned range of use, the hiding power is decreased and the coating film does not form more than the thickness required. If the use is over the above-mentioned range, the hiding power is greatly increased while the elastic force is dropped, resulting in a decrease in waterproof performance. Because it comes. In addition, various mixing ratios between the above components are matters that can be adjusted by any person having ordinary skill in the art, and thus, detailed descriptions thereof will be omitted.

In the present invention, the dispersant plays a role of evenly dispersing and storing stability and workability between the raw materials in the mixing process with other raw materials, when less than 0.1 parts by weight is not evenly dispersed between the raw materials and more than 1 part by weight The dispersing force and workability are improved, but it is preferable to use it within the above-described range of use because it may be a cause of peeling phenomenon due to a decrease in water resistance. Specifically, in the present invention, it is preferable to use a polyacrylate-based dispersant.

In the present invention, the antifoaming agent provides a role of suppressing the generation of bubbles or destroying the generated bubbles in the manufacture of the paint, when using less than 0.1 parts by weight, the durability of the coating film formed due to the foaming in the manufacture of the paint falls, 1 part by weight If exceeded, the viscosity rises due to excessive foaming suppression and workability is inferior. Therefore, it is preferable to use within the above-mentioned use range.

Preservatives act to prevent the coating composition produced from decay or collapse of the coating film, if less than 0.1 parts by weight of the product will lead to a shorter shelf life due to faster decay of the product, if more than 1 part by weight of the product has a minimal anti-corruption On the other hand, since it may cause problems such as peeling phenomenon due to a decrease in adhesive strength, it is preferable to use within the range of 0.1 to 1 parts by weight.

The thickener serves as a viscosity modifier to prevent the settling pigment from settling into the bottom of the container during storage of the finished paint composition, if less than 0.1 parts by weight, the storage stability is lowered due to the delamination of the raw materials, 1 weight Exceeding the portion, the product is inflated due to excessive viscosity increase and workability is significantly reduced, it is preferable to use within the above-mentioned range of use.

Texanol (2,2,3-Trimethyl-1,3-Pentanendiol Monoisobutyrate) plays a role in forming a coating film while allowing the paint to dry quickly. When less than 0.1 part by weight, the above-mentioned effects are insignificant and 1 part by weight When used in excess, the workability deteriorates, so it is preferable to use the above-mentioned use range.

In addition, in the present invention, the heat shielding pigment and the anti-settling agent are used in combination with a commercial product by a known method, and detailed and detailed description thereof will be omitted.

At this time, the dispersing agent, antifoaming agent, preservative, and thickener described above may use the components generally used by those skilled in the art of the present invention, so that any known one can be used as long as it meets the object of the present invention. Do.
