Abstract

The present invention is a one-part coating (liquid type) thermal insulation coating material used in various buildings and industrial facilities as a binder using a latex, acrylic emulsion and liquid silica-sol having excellent adhesive strength, and as inorganic filler, low thermal conductivity besides talc and silica. It is a product manufactured using micro ceramic filler, and has the advantage of showing insulation effect close to that of styrofoam, which is also commonly used as a thin film thickness (1-1.5mm).

1) Easy construction and finish only by coating, so no separate finishing work is needed.

2) The space according to the volume occupied by the existing insulation is reduced

3) It can replace the imported goods

4) Low thermal conductivity and energy savings

5) With insulation and condensation prevention

6) The adaptable temperature range of the material itself is -40 ℃ to + 280 ℃, which is adaptable to any climatic conditions and is a new technology product that solves all the problems of existing insulation materials (solid and liquid products).

Description

Liquid heat insulation coat (TEMP-COAT)

The materials currently used for insulation purposes in various buildings and industrial facilities include styrofoam, urethane foam, insulation materials for solid building and general insulation paint, but they do not exhibit sufficient insulation effect and have difficulties in durability and workability. have

In the case of styrofoam, the material itself has a large volume, which occupies a lot of space for the building, reducing the effective area, and urethane foam has the basic insulation effect due to the high film thickness, but there is a risk of fire due to lack of heat resistance. Problems caused by the leakage of toxic gas in the event of fire and disposal of a large amount of urethane foam waste caused by the demolition of buildings are also pointed out as major problems.

In addition, solid insulation materials are inconvenient in workability, and in the case of general insulation paints, the thermal conductivity is low, so the insulation effect is not large. Condensation caused by the temperature difference inside and outside the building due to the addition of a large amount of inorganic fillers The phenomenon can be prevented to some extent, but it is also difficult to achieve sufficient effects.

The present invention is a one-component liquid type thermal insulation coating material as a product of a new technology that solves all the problems of the existing various insulating materials

1) Because of the excellent thermal insulation effect due to low thermal conductivity, energy saving effect can be achieved for various buildings (thermal conductivity: 0.03Kcal / mh ℃: KSL 9016-95)

2) It has a high insulation effect even with a small film thickness, so it can increase the use space of the building.

3) As it is a liquid insulation material, it is possible to apply brushes, rollers, sprays, etc.

4) The use of silica sol and ceramic fillers has the advantage of preventing insulation and condensation of buildings.

Particularly, the silica-sol in the binder (binder) is a sol type material in which silica powder with low thermal conductivity is liquefied and can lower the thermal conductivity of the binder powder itself. In addition, the micro ceramic filler with low thermal conductivity Unlike the existing inorganic filler materials such as silica, talc, and calcium carbonate, it is possible to drastically lower the thermal conductivity of the product, and to disperse the binder powder properly is the core technology.

The present invention is a latex (latex), acrylic emulsion and silica-sol as a binder and as the inorganic filler using talc, silica and micro-ceramic fillers to increase the thermal insulation effect to reduce the energy used in buildings and thin film thickness It is a one-component liquid type thermal insulation coating material of new technology that can maximize the effective area of buildings as it is constructed (1-1.5mm).

The present invention will be described in detail through the following examples.

In the example, "part" is weight ratio.

Example

10-30 parts of latex, 10-30 parts of acrylic emulsion resin, and 10-30 parts of liquid silica-sol were gradually added to the production container, and stirred slowly at 40-60 ° C. for 30 minutes to 1 hour, followed by 10-30 parts of zinc oxide, and titanium dioxide. 10-30 parts, 5-15 parts of calcium carbonate are added and dispersed for 30 minutes by high speed agitation. The latex used can be CR, SBR, etc.

Next, the micro ceramic filler with low thermal conductivity is gradually added and aged for 2-5 hours after mixing and stirring. At this time, the binder is sufficiently wetted between the ceramic filler and other inorganic fillers to achieve a complete dispersion state. Ceramic filler is SiO2 / Al2O3 / Fe2O3 type and particle size is less than 10 micron.

Next, add about 2-5 parts of ethylene glycol or propylene glycol as a freeze stabilizer, and stir for 30 minutes. Then, mix 5-10 parts of water and stir at low speed for 20-30 minutes, and then use fine particle silica as thickener. -2 parts are added and the present invention is completed after 1 hour of aging.

As a result of the thermal conductivity test, 0.03Kcal / mh ℃ (KSM 9016-95) was obtained as the above product. It can be expanded and solve the waste disposal problem of urethane foam which is used as the existing insulation.

In addition, it can be said to be a new technology product that can replace the import effect of the liquid type heat insulating material currently imported and used.
