Description

TECHNICAL FIELD [0001] The present invention relates to a natural interior material containing natural minerals,

The present invention relates to a building interior material, and more particularly, to a building interior material which can be used as a building interior, a vehicle, an aircraft, a ship, an amusement facility, a theme park, a sound device, a speaker, And the inner side walls are made of at least one of natural minerals such as ililite, kaolin, ocher, mica stone, pozzolan, ore ore, clay, and vermiculite, which are environmentally friendly materials, , Anti-virus, blood circulation and metabolism. It activates aged cells to promote excretion of waste products and lipids, thereby eliminating the cause of skin aging and maintaining health and youthfulness. Natural pulp or natural fiber, which is used to increase the sound absorption, flame retardancy, and heat insulation. It relates to a process for producing architectural interior material with water and them.

In general, architectural interiors are substitutes for wood, and they are superior in design diversification and productivity. However, due to the heterogeneity of the materials, their appearance is poor and the thermal expansion coefficient is large, resulting in warping after construction, lack of elasticity, Or most of it is odorous and toxic, the main cause of which is the gradual release of residual formaldehyde and health problems.

Formaldehyde, which occurs in the building interior materials mainly made of synthetic resin, is known as a substance which stimulates nose and eyes with irritating gas and is suspected to cause diseases in humans and animals, and environmental concern is increasing worldwide And the emission is restricted due to the tightening of regulations in 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.

On the other hand, in general, with the massive supply of buildings, the claim of residents demanding a pleasant living environment is increasing day by day as the level of living and awareness of living increase. As the disputes with neighboring households become more frequent due to noise, It is gradually becoming shrinking.

In recent years, the noise of floor impact systems such as children's running noise and walking footsteps caused the complaints of the residents because of the speciality of sharing the walls and floors with the neighbors. And the residential environment performance related to the sound insulation performance is important for the comfortable living environment and the privacy of the residents. It is no wonder that a lot of households live in a wall or a floor with one another in the house, so there is a problem of sound insulation. The reasons for such noise problems are the changes in human relationships due to self-centered living, changes in the sound source as the living standard improves, and changes in the performance requirements of the residents. However, the more fundamental problem is the nature of the material used and the problem with the construction method. The concrete used in the apartment house is heavy and is a closed room due to the nature of the material. Therefore, the barrier is good for the noise (air transmission sound) transmitted by air, such as a voice or TV sound, to other materials of the same thickness. However, due to the nature of the material, the impact sound (solid transmission sound) generated by the direct impact on the concrete surface is easily transmitted to the adjacent generation. These characteristics are often experienced by people who live in apartment houses. Typical examples are sounds from upper floors, falling objects, etc. Even if the frequency of occurrence is not high, it is an unpleasant noise source. Therefore, such a noise source causes the complaints of tenants. This noise is an important factor that determines the quality of the residential environment. Among them, the floor impact sound between the generations is a solid sound transmission. When the impact force hits the bottom, impact energy is applied to the floor slab of the mortar, insulation layer (lightweight foam concrete, styrene foam) It is best not to generate the impact source itself in order to reduce the floor impact sound, which is transmitted by vibrating the floor slab so that the emitted sound is decomposed. However, it is impossible to realistically develop a new interlayer noise reducing material as a method to minimize impact energy. Therefore, a sound absorbing material (sound absorbing material) which is used to supply a pleasant apartment and improve the quality by applying a building material having sound insulation, vibration suppression and dustproof effect is a building material used for the purpose of absorbing sound, And plate-like sound-absorbing materials. The porous sound-absorbing material has fine bubbles or fine-tube-shaped holes formed on its surface and inside, and the sound energy is converted into heat energy and absorbed due to the friction caused by the air inside the holes being vibrated by the sound waves . The plate-like sound absorbing material obtains a sound absorbing effect by consuming sound energy while the sound waves vibrate the plate.

In order to secure the sound absorption performance of such a sound-absorbing material, synthetic fibers such as polyester and polyurethane are generally used. Since the sound-absorbing agent is widely used as an interior material, it is important to have flame retardancy. The flame retardant mainly used is a halogen-based flame retardant and a phosphorus-based flame retardant. However, since synthetic fibers such as polyester and polyurethane have high flammability, a large amount of flame retardant should be used. However, if the flame retardant is used in an excessively large amount, the sound absorbing performance of the sound absorbing material deteriorates. And the manufacturing cost of the sound absorbing material is also increased. Above all, such a sound absorbing material has a problem that it is difficult to obtain a flame retardancy exceeding a certain level even if the amount of the flame retardant is increased.

On the other hand, there are many kinds of odorous substances including ammonia in our daily life. Sulfur compounds such as hydrogen sulfide and mercaptan, nitrogen compounds such as ammonia, scatol, and amine, and fatty acids such as formic acid and acetic acid, and the like. In recent years, as the level of living has become more sensitive to odor, the odor that gives an uncomfortable feeling of life is defined as pollution, and regulations under the related laws are strengthened. Various methods have been used to remove such odors. There are four types of deodorization methods currently in use.

The first is a sensory method that uses fragrance, which does not remove a basically stinky substance by making it impossible for a person to smell bad smells by using stronger fragrance than a bad odor in a bathroom or room . Spices added to most of these deodorants are easily diffused indoors and accumulate in the lungs during breathing, which can be harmful to the human body during long-term use.

The second is a physical adsorption method, which is a typical de-aeration method using activated charcoal. Charcoal adsorbs odorous substances with a porous material with a surface area of 1 g of about 300 m ² . It takes a relatively long time to deodorize, and if the odor particles are adsorbed to the pores of the activated carbon, the adsorbed particles can no longer be adsorbed. Therefore, there is a disadvantage that the used activated carbon must be replaced regularly.

The third is a chemical treatment method. As a typical method, chlorine dioxide is a substance that is mainly used for oxidizing odor molecules.

The fourth method is to enclose the odor particles and confine them in a specific molecule to obtain the deodorizing effect. Materials such as flavonoids, hydroxypropylbetacyclodextrin and zinc chloride are used in this method. Although most of the deodorizers are diluted or dispersed in the form of a short deodorant, a limited deodorant which only deodorizes some of the substances causing the odor, It has a range of limitations. When these products are sprayed using a spray, the deodorizing component is accumulated in the body through the respiratory apparatus, and therefore, there is a problem in that care is required for long-term use.

The binder material serves as an adhesive for bonding one of the natural pulp and the natural fiber to various additives.

The construction interior material of the present invention is completed by combining a magnesium board 200 having a plurality of through holes 210 formed therein with an adhesive material at the lower end of the building interior body 100 manufactured as described above.

Hereinafter, the process for manufacturing the natural building material containing natural minerals according to the present invention will be described in more detail.

First, a first mixture production step (S1) is performed for manufacturing the building interior material main body 100.

The first mixture-producing step (S1) may be carried out by mixing at least one of natural minerals such as ilite, kaolin, loess, mica, pozzolan, biotite, clay and vermiculite with 100-1,000 mesh A weight ratio of one fine powder to natural pulp or natural fiber and water is 1 to 3: 1 to 3: 3 to 15 to produce a mixture.

Next, at least one kind of oil selected from the group consisting of 1 to 5 g of a binder material per the first mixture 100, 1 to 5 g of an expanding agent, 5 to 30 g of a flame retardant, 0.1 to 5 g of a flour and 0.1 to 5 g of tea tree oil, castor oil and flaxseed oil A second mixture is produced through a second mixture producing step (S2) in which 1.0 to 10.0 g of calcium complex or zinc complex is added and mixed.

Next, a molding step (S3) for molding the mixed mixture in the second mixture producing step (S2) into a predetermined shape may be performed. In the molding step (S3), for example, the second mixture may be injection molded into a panel shape or the like by an injection molding machine.

Next, in the drying step S4, the building interior main body 100 formed in the molding step S3 is dried by a dryer, and the dryer is a microwave dryer of 15 to 24 mm, and is dried in the dryer at 60 to 100 DEG C S4 may be performed.

Preferably, the drying step S4 includes a first drying step S4-1 and a second drying step S4-2. The first drying temperature of the first drying step S4-1 corresponds to the second drying temperature of the second drying step S4-1. It is set to a relatively low temperature value as compared with the drying temperature. For example, the first drying temperature may be set to a room temperature, that is, a temperature of 15 to 25 ° C, and the second drying temperature may be set to a temperature of 60 to 100 ° C. The first drying time may be set to a relatively short time as compared with the second drying time. For example, the first drying time may be set to a time within 1 hour, and the second drying time may be set to a time of 10 hours or more.

That is, in the present embodiment, the first drying step (S4-1) is performed for a relatively short time at a relatively low temperature, the second drying step (S4-2) is performed for a relatively long time at a relatively high temperature, . If the sound absorbing material containing a considerable amount of moisture is dried at a relatively high temperature immediately, there may occur a case where the building interior main body is bent or a crack is formed in the building interior main body. Therefore, in the present embodiment, the building interior material is primarily dried at the first room temperature, and then is secondarily dried at a high temperature when a certain amount of moisture is evaporated.

Finally, a cutting step S5 for cutting the dried building interior material to a predetermined size in the drying step S4 may be performed. In the cutting step (S5), the building interior material is cut into a predetermined size, and the building interior material can be cut to a size that can be used in an actual construction site by a cutting machine.

More preferably, as shown in Fig. 3

Compared to the conventional building interior material, the building interior material produced in this way can exhibit the effect of being beneficial to the human body as compared with the existing building interior material due to the emission of far-infrared rays and anions due to the inclusion of natural minerals. The most representative example of the conventional architectural interior materials is a wood-wool board, that is, a wood fiber interior material, which is formed by compressing wood fibers and an inorganic binder at a high temperature and a high pressure. However, either natural pulp or natural fiber absorbs sound absorption better than wood fiber. Therefore, the construction interior material of the present invention, which uses either natural pulp or natural fiber as a main raw material, has better sound absorption performance than conventional building interior materials using wood fiber as a main raw material. Table 2 below compares the sound absorption performance of the building interior material having the sound absorption function according to the prior art and the building interior material according to the present embodiment by the noise frequency.

[Table 2] shows the absorption coefficient for noise of each frequency under the temperature condition of 23.7 ~ 25.4 ℃ and the humidity condition of 53.8 ~ 55.6% R.H. In Table 2, the architectural interior material according to the prior art is made by adding wood fiber as a main material and various additives other than wood fiber. Therefore, as shown in [Table 2], it can be said that the construction interior material according to the present embodiment has superior sound absorption performance as compared with the construction interior material according to the prior art.

The building interior material according to the present embodiment exhibits excellent deodorizing performance as compared with conventional de-covering.

In order to confirm the deodorization performance of the building interior material of the present invention, propylene glycol monomethyl ether acetate (PGMEA), which is widely used as a cleaning agent for formaldehyde, acetone, and electronic circuit, which are main causes of odor, ammonia, trimethylamine, Were subjected to a deodorization test. As a concrete test method, specimen pieces (1 mm thick, 10 cm wide and 10 cm long pieces of specimens) each having a suitable size were cut into a container of 5 L volume, and each odor sample gas was individually forced After the injection, the deodorizing performance of each gas was measured by measuring the residual gas concentration in the container containing the specimen pieces with a test measurement time of 2 hours. [Table 3], [Table 4], [Table 5] and [Table 6] below show the test results for each deodorization test.

Test Items Test result Odor Sample concentration (ppm) Deodorization rate (%) ammonia 0 minutes 500  0.0 30 minutes 27 94 60 minutes 20 96 90 minutes 14 97 120 minutes Less than 1 100

As can be seen from the above experimental results, it can be seen that the concentration of the odor sample decreases significantly with the lapse of time, and thus the excellent deodorizing performance of the architectural interior material of the present invention can be confirmed. Especially, in the initial deodorization rate, unlike conventional deodorization, it can exhibit a high deodorizing effect that removes almost 90% of the odor within 30 minutes of the generation of odor.
