Description

Environmentally friendly construction Non-burning, insulation, sound absorption, heat insulation, waterproof and mineral bio-functional interior finishing board manufacturing method and eco-friendly construction manufactured by this manufacturing method Non-burning, insulation, sound absorption, heat insulation, waterproof and mineral bio functional interior finishing board {ECO BUILDING INTERIOR BOARDS AND METHOD FOR MANUFACTURING THEREOF}

The present invention relates to a building interior finishing board. More particularly, the present invention relates to a building interior finishing board, and more particularly, to provide a comfortable interior environment by providing minerals-rich biomaterials that are beneficial to the human body as well as fire retardance, heat insulation,

Architectural interior materials have been manufactured in various factories for fire protection, flame retardation, light weight, high quality and price reduction.

Particularly, the building interior material mainly made of synthetic resin is used as a substitute material for wood or steel, and is mainly used for general building material, furniture, or various household goods. For example, flooring material, ceiling material, side wall material, .

Such an architectural interior material is a substitute for wood, and it was superior in diversity of design and productivity, but its appearance was poor due to the heterogeneity of materials, and the coefficient of thermal expansion was large, resulting in warping after construction, lack of elasticity, , Most of which are odorous and toxic, the main cause of which is the gradual release of residual formaldehyde and health problems.

Formaldehyde, which is generally generated from synthetic resin interior materials, is a stimulant gas that stimulates nose and eyes and is suspected to cause illness in humans and animals. Environmental awareness is increasing worldwide And the emission is restricted due to strengthened regulations of each country.

Formaldehyde resins have been widely used as adhesives in the manufacture of wood materials, especially medium density fibrous sheets, and other plate materials. Representative examples of such formaldehyde resins are melamine resins, urea resins, and the like, which are produced by the addition condensation of phenol, melamine, urea and formaldehyde.

Therefore, various methods for reducing formaldehyde remaining in the resin are being studied in various fields in the industry.

Generally, yellow loess, jade, and ceramics are synthesized with adhesives, and they are widely used as building materials, etc. Also, there is a technique of mixing anion with paint or the like, and anion powder is added to a binder and adhered to fibers.

For example, Korean Unexamined Patent Publication (Kokai) No. 2003-75712 discloses a method of manufacturing a lightweight nonflammable building material by compression molding of a high-temperature and high-pressure expanded perlite, vermiculite, cement, lime, In Publication No. 2003-76482, there is disclosed a fire-retardant furniture interior material and a fire-retardant interior material panel product produced by compression-heating with the addition of a non-combustible saturated ceramic adhesive to a vermiculite, and in Publication No. 2000-37956, , Yellow loess, synthetic resin, antimicrobial agent, hectorite, soybean oil, wood powder composed of chemical materials, and synthetic resin material containing loess as a main component are publicly disclosed. In Publication No. 2000-37956, pearlite, cement, endotherm, carboxymethyl A fireproof thermal insulation coating composition composed of cellulose soda powder, coconut, and dimethanolamide, and a method for producing the same, Open No. 10-2004-11404 discloses a method for producing a molded article using a mica stone made of mica stone and an adhesive, and Korean Utility Model Registration No. 20-0328608, which is composed of a veneer and a surface coating layer, Anodic-function flooring material with an anion added with an anion material selected from tourmaline and rare-earth minerals in at least one or more layers in a structure composed of an upper layer, an adhesive layer, and a base layer is disclosed in JP-A No. 20-0335182 A plywood is pressed and fixed to the first adhesive layer in which activated carbon is mixed, an adhesive layer formed by mixing melamine resin, torgari and activated carbon is applied to one side of the plywood, and an anion and a far-infrared ray A flooring material is described in Japanese Unexamined Patent Application Publication No. 20-034776, wherein a plurality of single plates are laminated in the same wood grain direction The physical properties and properties of the wood board are the same as those of natural wood and are composed of a functional adhesive composed of a thermosetting resin containing any one of yellow clay, jade, germanium, charcoal, silver, copper, copper, However, the conventional artificial building interior materials as described above have a problem in that the manufacturing method is complicated and the formaldehyde can not be completely reduced, so that it can not be used practically.

On the other hand, there is a conventional built-in board (a mixture of perlite, sawdust, silica sol, etc.) using perlite, which is manufactured by pressing a material into a certain frame and pressing it with a press machine. The pore of the foamed perlite is destroyed and the function of the heat insulation is degraded. In the existing product technology, since the natural drying and the water are mixed and diluted at a low temperature, the combined property of waterproof property and heat insulating property is poor, There is a problem that it is structurally weak and easily damaged. Also, even if the pearlite is not damaged, the conventional built-in board can not exert the functions other than the pearlite, so that the surface shape is not good to be used as the interior finishing material, and it is burnt and broken so that the interior can not be formed in a comfortable environment.

Fireproof and insulation, sound absorption, heat insulation, waterproof and mineral bio functional interior board manufacturing method and eco-friendly construction manufactured by this manufacturing method Fireproof, insulation, sound absorption, Mineral bio functional interior finishing board is intended to provide.

According to the present invention, there is provided an eco-friendly building fireproof, insulation, sound absorption, insulation, waterproof and mineral bio functional interior finishing board comprising at least one main material selected from the group consisting of perlite and vermiculite; A binder consisting of at least one of liquid sodium silicate, liquid potassium silicate, silica sol and alumina sol, and binding the main material; The binder is made of at least one of magnesium oxide (MgO), iron oxide (Fe203), titanium oxide (TiO2), aluminum oxide (Al2O3), calcium carbonate (CaCo3), and zinc oxide (ZnO) An insoluble and waterproof curing agent; Wherein the binder is made of at least one selected from the group consisting of granite powder, elvan powder, jade powder, zircon powder, zeolite and talc, and accelerating curing of the binder and releasing mineral elements.

1 is a photograph of a state in which a flame is applied,
FIG. 2 is a photograph showing a side to which a flame is applied after applying a flame,
3 is a photograph showing the temperature on the opposite side of the flame.

The eco-friendly building fireproof, insulation, sound absorption, heat insulation and waterproofing, and mineral bio-functional interior finishing board according to the present invention is characterized by comprising at least one main material selected from the group consisting of perlite and vermiculite, And an admixture which accelerates curing of the curing agent and emits a biomolecule (far-infrared ray, anion, etc.).

The main materials, perlite and vermiculite, have the following characteristics.

The perlite is a lightweight aggregate used as a raw material for fire-proofing, heat insulating materials and sound absorbing materials. It is a powder having a particle size of 1 to 8 mm. A first perlite powder having a particle size of 1 to 3 mm, a second perlite powder having a particle size of 4 to 6 mm, Of the third peroxide powder are mixed at a weight ratio of 1: 1.5 to 3.0: 2.5 to 3.0.

The reason why the first, second and third perlite powders having different particle sizes are used is that, when only the second and third perlite powders are used, a void space is formed between the second and third perlite powders, To prevent degradation. Although only the first peroxide powder may be used, the cost is increased and the supply and demand is not smooth and there is a risk of loss during handling. The first, second and third perlite powders are commercially available products that can be purchased commercially.

The first, second and third peristaltic powders may be used by mixing two or more thereof.

The vermiculite is widely used as a heat-resistant material and a sound insulating material as a porous material, and a material having the same particle size as the above-mentioned perlite is mixed and used.

Conventional products are manufactured by natural drying at a low temperature and have no water resistance, and they are not used as a surface finishing material due to cracking due to no insulation and surface adhesion due to high pressure and aqueous bonding, and molds are generated. In order to solve this problem, the binder is composed of a mixture of liquid sodium silicate, liquid potassium silicate, silica sol and alumina sol.

Wherein the binder is a mixture of 55 to 65 wt% of liquid sodium silicate, 20 to 30 wt% of liquid potassium silicate, 5 to 10 wt% of silica sol, and 5 to 10 wt% of alumina sol when four kinds are used together, 60 to 80 parts by weight of the perlite powder (or a mixture of vermiculite or vermiculite and vermiculite, hereinafter referred to as perlite) is mixed as a main ingredient.

Sodium silicate can be used in powder form as well as in liquid phase. It can be used as an inorganic binder and exhibits a high adhesive strength. It also serves as a fireproofing function and less tacky. It can prevent the waterproof bonding and the breakage of powder on the surface of the product. When mixed, the adhesive strength of the main material such as pearlite is weak, and even when mixed in an amount exceeding 65% by weight, there is not much change in the adhesive force.

The liquid potassium silicate dissolves well with other materials to increase the adhesive strength. When less than 20% by weight is mixed, the meltability is weak. When the amount is more than 30% by weight, the solubility and the adhesive strength are not greatly changed.

Silica sol is a liquid phase which is a colloid in which fine particles of silicic acid (SiO ₂ n n H ₂ O) are dispersed in a dispersion medium such as water and is used for bonding materials such as sodium silicate and alumina sol, %, The bonding strength between the materials is weak and the strength is weakened. When the content is mixed at 10 wt% or more, the workability is lowered.

The alumina sol accelerates the bonding of materials, and a water-soluble liquid phase is used, and if it is out of the range of 5 to 10 wt%, the bonding force between the materials is weak, which weakens the strength and lowers the workability.

The four kinds are mixed to produce the optimum binder. Since the binder can perform its function even if the four kinds are not all mixed, the four kinds are not limited to being used together, and two or more types The mixing ratio can be mixed at an equal ratio on the basis of weight, and the mixing ratio is not limited thereto since there is no difference in binding by type.

60 to 80 parts by weight of the binder is mixed in an amount of 60 to 80 parts by weight per 100 parts by weight of the pearlite. When the amount of the binder is less than 60 parts by weight, the pearlite particles are weakly bonded to each other. The castle falls.

The insoluble and waterproof curing agent is composed of at least one of magnesium oxide (MgO), iron oxide (Fe203), titanium oxide (TiO2), aluminum oxide (Al2O3), calcium carbonate (CaCo3) and zinc oxide (ZnO) The binder reacts with the binder to cure the binder while exhibiting insoluble and waterproof characteristics, and 5 to 20 parts by weight of the binder is mixed with 100 parts by weight of the binder. When less than 5 parts by weight is mixed, the curing rate is delayed or the curing degree is weak, and when it is mixed with more than 20 parts by weight, workability is deteriorated due to rapid and excessive curing.

Magnesium oxide (MgO), iron oxide (Fe2O3), titanium oxide (TiO2), aluminum oxide (Al2O3), calcium carbonate (CaCo3) and zinc oxide (ZnO) are mixed freely under conditions satisfying the mixing ratio range to the binder .

As the admixture, at least one of an elvan powder, a jade powder, a zircon powder, a zeolite and a talc having a particle size of 100 to 500 μm is used, and 5 to 10 parts by weight of the admixture is mixed with 100 parts by weight of the binder.

Although the above-mentioned admixture differs slightly depending on materials, it ion-reacts with the curing agent to accelerate the curing of insolubility and waterproofness, and emit functional minerals, far-infrared rays and anions, and also functions as fire retardant, As well.

The materials of the admixture are mixed at a free mixing ratio as in the case of the curing agent.

The eco-friendly construction of the present invention is as follows: fireproof, insulation, sound absorption, insulation and waterproof, and mineral bio-functional interior finishing board manufacturing method.

At least one of magnesium oxide (MgO), iron oxide (Fe203), titanium oxide (TiO2), aluminum oxide (Al2O3), calcium carbonate (CaCo3) and zinc oxide (ZnO) is prepared as a hardening agent.

As the admixture, at least one of an elvan powder, a jade powder, a silica powder, a zeolite and a talc is prepared.

3. Built-in finish board manufacturing.

The size of the mold can be variously changed. For example, it is possible to manufacture the mold from 9T to 30T, 45T and the width and length from 300 x 600 to 1200 x 2400 have.

The above material contained in the mold is pressed, aged at a low temperature, cured at a middle temperature and high temperature to form a board. Curing can be both natural curing and forced curing. However, since hardening takes a long time during natural curing, productivity lowers, Heating and near infrared curing are desirable with strength and high temperature curing systems.

The drying and curing conditions include primary drying at 90 to 120 ° C for 10 to 30 minutes, secondary drying at 200 to 250 ° C for 10 to 30 minutes and drying at 300 to 350 ° C for 10 to 25 minutes for the near infrared ray for aging.

In addition, the built-in finishing board can be pressed to make the built-in finishing board more rigid, and the pressing conditions are from 150 to 250 ton pressure for 3 to 7 minutes, preferably 200 ton pressure for 5 minutes. If the pressing condition is out of the range, the increase of the strength is weak, and cracks of the built-in finishing board may occur due to excessive pressing.

On the other hand, it can be processed so as to form concavo-convex portions on the surface during pressing. For example, recesses and protrusions are formed on the surface of the press so that the recesses and protrusions are formed together with the pressing.

Products that have been cured and pressed can be stabilized through low temperature aging drying (150 ~ 300 ℃, 10 ~ 30 minutes). The present process is a process different from the above-described drying process, and is for the curing and aging of the press-completed product.
