Conventional building finishing materials as described above help to reduce the sick house syndrome, but in general, the temporary effect is usually obtained after construction, and the purification and purification of indoor air due to the extremely low adsorption rate and decomposition rate of various harmful substances such as volatile organic compounds and formaldehyde There is a problem that the efficiency is low and still emit harmful substances.

The present invention has been made to solve this problem, and to promote the adsorption and decomposition of various harmful substances such as organic compounds, formaldehyde, etc., by firing fine powder silica of 5-6 nanoparticles to activate the pores The photodegradation effect of adsorbing and desorbing harmful gases, the viscosity increase and dispersion effect by fine powder silica of 2-3 nanoparticles, the far infrared and anion are generated by tourmaline and the vibration wave energy of far infrared ray. The present invention provides a method of manufacturing a functional building material and a functional building material that can be used in a harmless and environmentally friendly manner, including lithium silicate as an effect and binder to enhance the adsorption and decomposition efficiency.

The present invention comprises the steps of calcining fine powder silica having a particle diameter of 5 to 6 nanometers: adding a dispersant to water and mixing and stirring; Mixing and stirring the calcined fine powder silica of 5-6 nanoparticles with fine powder silica having a particle size of 2-3 nanometers and fine powder tourmaline having a particle size of 5-6 nanoparticles to the resultant of the step so that the composite is uniformly dispersed. Wow; Adding and stirring a binder consisting of lithium silicate and EVA to the result of the step; And a step of sequentially adding an antifoaming agent and a thickener to the resultant of the step.

The fine powder silica of 5-6 nanoparticles is 18-22 parts by weight, 5-10 parts by weight of fine powder silica of 2-3 nanoparticles, 2-4 parts by weight of fine powder tourmaline of 5-6 nano, 28-32 parts by weight of lithium silicate, 4 to 6 parts by weight of EVA, 0.5 to 1.0 part by weight of dispersant, 0.5 to 1.0 part by weight of antifoaming agent, 0.2 to 0.4 part by weight of thickener, and 30 to 36 parts by weight of water.

The fine powder silica of 5 to 6 nanometers is characterized in that by firing for 5 to 7 hours at 180 ~ 220 ℃ in the kiln.

1 is a block diagram showing a manufacturing step of the functional building finish material according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention comprises the steps of firing fine powder silica having a particle diameter of 5 to 6 nanometers (S1) and: adding a dispersant to water and mixing and stirring (S2); Mixing and stirring the calcined fine powder silica of 5-6 nanoparticles with fine powder silica having a particle size of 2-3 nanometers and fine powder tourmaline having a particle size of 5-6 nanoparticles to the resultant of the step so that the composite is uniformly dispersed. (S3); Adding and stirring a binder made of lithium silicate and EVA to the resultant of the step (S4); To prepare a functional building finishing material comprising; step (S5) to sequentially add a defoaming agent and a thickener to the result of the step.

These functional building finishes are powdered into 5-6 nanoparticles and calcined to 18-22 parts by weight of fine powder silica, 5-10 parts by weight of fine powder silica of 2-3 nanometers, and 2-4 parts by weight of fine powder tourmaline of 5-6 nano. And 28 to 32 parts by weight of lithium silicate, 4 to 6 parts by weight of EVA, 0.5 to 1.0 parts by weight of dispersant, 0.5 to 1.0 parts by weight of antifoaming agent, 0.2 to 0.4 parts by weight of thickener, and 30 to 36 parts by weight of water.

In the above, 5 to 6 nano fine powder silica is to increase the strength of the finishing material, while the effect of allowing the adsorption and decomposition of harmful substances in a number of pores, while 5 to 6 nano fine powder silica activates the pores more. In order to make the firing in the kiln for 5-7 hours at 180 ~ 220 ℃ to increase the size of the pores 3 to 4 times to have a continuous adsorption, decomposition.

The fine powder silica of 5-6 nanoparticles may contain 18 to 22 parts by weight, but if the content is less than 18 parts by weight, there may be a problem in that the adsorption and decomposition effects are weak and the content may exceed 22 parts by weight.

The lithium silicate is used as an inorganic binder having a molar ratio of about 40%, and it is environmentally friendly as it is a property of strengthening the surface of the cement and concrete to penetrate and react to the surface of cement and concrete, but the adhesion to the coating surface is inferior to organic By combining a small amount of EVA (ethylene vinyl acetate) as a binder to improve the adhesion stability by complementary properties between organic and inorganic components, when the lithium silicate is less than 28 parts by weight, the amount of EVA organic binder is relatively increased There is a problem, and if the amount exceeds 32 parts by weight, the amount of EVA is reduced, so there is a problem that the adhesive force is lowered, it is preferable to contain 28 to 32 parts by weight.

The EVA (ethylene vinyl acetate) is an organic binder to combine with the lithium silicate to have adhesion stability, the lithium silicate is cured when the polyvinyl butyral (PVB) polyvinyl alcohol (PVA) and the like combined with the organic binder Since there is a property to lose the adhesive force, the lithium silicate is combined with EVA to have fluidity, but EVA is less than 4 parts by weight, the adhesion is lowered, if more than 6 parts by weight there is a problem that the chemical resistance increases.

And 0.5 to 1.0 parts by weight of dispersant, 0.5 to 1.0 parts by weight of antifoaming agent and 30 to 36 parts by weight of water are mixed therein to obtain a finish.
