The present invention relates to a method for producing a functional building interior material using a cap material.

Typically, the foamed styrofoam is attached to the interior and exterior walls of the building to maintain a constant temperature and sound insulation inside the building, which is called a building interior material. Such building interior materials are manufactured in various ways, such as alternately stacking a plurality of foamed styrofoam and glass fibers and packaging the plastic to remove internal air to improve insulation and sound insulation.

As an example of building interior materials, Korean Utility Model Publication No. 20-0407098 "Architecture Insulation Material" is published.Aluminum foil and nonwoven fabric bonded with a transparent PET film are bonded with a synthetic resin to form a resin adhesive layer, and a nonwoven fabric and a foamed PE resin. Embossing was formed on aluminum silver foil in the state of thermal bonding, so that it has a long life and high insulation and sound insulation effect.

However, the related art is a technical idea that all materials are vulnerable to heat, and in the event of a fire, a large amount of toxic substances harmful to the human body and the natural environment are released.

On the other hand, the air cap is a plastic that is soft and soft to the touch because it is transparent and thin, and in particular, a plurality of air layers are formed in a predetermined arrangement, and used as a cushioning material for packaging of an object that may be damaged or used as a heat insulating material for a home window.

It is a technology that can prevent the growth of mold by preventing condensation by improving the insulation effect of the building by preventing the phenomenon of the head passing through the insulation.

However, in the above technical concept, all materials are vulnerable to heat, and in the event of a fire, a large amount of toxic substances harmful to the human body and the natural environment are released, and an air cap is placed between the flat insulations, resulting in loss of function of the air ball due to external impact. Such problems can not be solved the problems of building interior materials using air caps.

However, in the above-mentioned prior art and all the prior arts, the air caps are merely bonded to the heat insulating materials, and ultimately, the technical ideas cause the air ball to be deformed by the crimping of the heat insulating materials. Because of this loss, technical ideas are required to solve these problems.

Hereinafter, with reference to the accompanying drawings will be described in a batch about the configuration of the present invention and its effects, effects.

Advantages and features of the present invention, and methods for achieving them will be apparent with reference to the embodiments described below in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be embodied in various different forms, and only the present embodiments are provided to make the disclosure of the present invention complete and common knowledge in the technical field to which the present invention belongs. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. And like reference numerals refer to like elements throughout the specification.

The present invention relates to a building interior material is maximized insulation and sound insulation in the building.

In particular, the present invention, unlike the existing air cap using a specific material is not only positively improved the effect of insulation and sound insulation, but also added a flame retardant material made of a high molecular compound is given an excellent level of flame retardant function, and further in the grain Note that the use of extracted natural synthetic resins and eco-friendly adhesives significantly reduces the amount of pollutants generated during incineration or disposal, and thus relates to the manufacturing method of functional building interior materials using eco-friendly air caps, which exhibits environmentally friendly benefits.

1 is a flowchart sequentially listing the manufacturing method of a functional building interior material based on an eco-friendly air cap constituted by a preferred embodiment of the present invention, the construction of the object level by the sequential implementation of the detailed steps to be described later and the mixing of all elements Acquire interior materials.

Functional building interior material of the present invention as shown in Figure 1 is largely a heat insulating material molding step (S100) for producing a heat insulating material; and, an air cap molding step (S200) for manufacturing an air cap; and, heat insulation prepared as described above Consists of a thermal insulation material bonding step (S300) to integrate the material and the air cap to be integrated.

The above insulation material molding step (S100) is a process of forming an individual space 11 made of polygons in a foamed styrofoam to form a predetermined pattern, wherein the foamed styrofoam is all insulation that can be processed by a person skilled in the art It comprises a functional material, and preferably comprises a foamable polyethylene resin processed by adding a blowing agent and a curing agent to the polyethylene resin.

On the other hand, the above step of forming a short material (S100) by arranging a plurality of foam insulation bars (bar) made of a thickness of 0.5cm ~ 1cm cross each other by arranging in the shape of any one of rhombus, diamond, honeycomb (multiple individual spaces) 11) is provided.

Honeycomb arrays in particular have the best function in terms of insulation and sound insulation. In this case, the honeycomb array is 360 ° by collecting three regular hexagons of 120 ° in each vertex at each vertex. In this case, it can be represented as (6, 6, 6). It can be found in the cross section of honeycomb because it is related to the shape of honey house. When the length of the circumference is constant in the cut section of the honeycomb, the widest area is the regular hexagon, and in the three-dimensional diagram, it is the regular hexagonal column that guarantees the maximum volume among the regular square columns.

As described above, the heat insulating material 10 adopting the honeycomb array is used in various products because it uses less material and is strong in bending and compression with a light and rigid structure.

For the above reasons, if the individual space 11 of the heat insulating material 10 is configured in a honeycomb array, a small amount of foamed styrofoam can secure the maximum individual space, and the individual space thus secured increases the insulation and sound insulation effect. You can expect. In addition, the addition amount of the foamed styrofoam, which is a combustible material, is useful for preventing fire and the production cost is reduced, which is advantageous for mass production.

The air cap molding step (S200) is a process of manufacturing the air cap 20 by melt molding polyethylene and flame retardant materials and natural synthetic resin. In particular, the core technology is to alternately form the arrangement position of the air ball 21 in the individual space 11 of the insulating material 10 in the molding process.

The air cap molding step (S200) is a main material generation step (S210) for generating the basic components of the air cap; and a natural synthetic resin production step (S220) for manufacturing a natural synthetic resin to add environmentally friendly elements to the air cap; And a flame retardant material producing step of manufacturing a flame retardant material for imparting a flame retardant function to the air cap (S230); and a flame retardant material adding step of forming a shape of an air cap while applying the flame retardant material (S240). .

The main material generation step (S210) is divided into the main component polyethylene and secondary components acrylonitrile, antimony, decapron, and prepared by grinding to 0.5 ~ 0.8 ㎛ size so that each component can be perfectly fused to each other, These particle sizes are based on information obtained from the following experimental results.

For the experiment, each component was ground to a size of 0.1 ~ 0.5㎛, 0.5 ~ 0.8㎛, 1 ~ 1.5㎛ and then prepared by mixing each of the components crushed to the same size, per area from the specimens separated by each size It was measured in order of distribution, surface texture, durability, heat insulation, and flame retardancy.

The measuring method is as follows.

* Distribution per area: The distribution of specimens per 100 mm2 of polyethylene was measured, and the numerical value decreases every time the distribution of specimens was small based on 1: 1 distribution.

* Surface Texture: A surface roughness meter manufactured by Mitutoyo that measures the entire surface of polyethylene using SJ-210, which can measure up to 360 µm (-200 µm to +160 µm).

* Other durability, insulation, and flame retardancy measured the internal temperature of the facility by installing the insulation material with each specimen added to the test wall and leaving it for a certain period of time, and measuring the durability and flame retardance according to the corrosion degree of the insulation material.

<Comparison of Air Cap Performance According to Particle Size>

As shown in Table 1, while the distribution per surface area, surface texture, durability, heat insulation, flame retardancy, and light transmittance of the specimens molded from 0.1 to 0.8 μm were excellently aggregated, the specimens molded from 1.0 to 1.5 μm were obtained. Surface texture and durability were slightly lower than those of specimens molded from 0.1 to 0.8 μm crushed components.

On the other hand, although the performance of the specimens molded with the components pulverized to 0.1 ~ 0.5㎛ was slightly superior to the performance of the specimens molded with the components pulverized to 0.5 ~ 0.8㎛, it was molded with the components pulverized to 0.1 ~ 0.5㎛ One test piece has a problem that the manufacturing cost is significantly higher than 0.5 ~ 0.8 ㎛ high productivity, as well as a considerable time when grinding.

As a result, it was confirmed that the manufacture of a predetermined air cap by grinding to 0.5 ~ 0.8㎛ gives the same function but excellent manufacturing process.

The above-mentioned natural synthetic resin generation step (S220) is divided into the process of manufacturing a general material to give an environmentally friendly element to the air cap made of polyethylene as follows.

Carbon powder extraction step (S221) for pulverizing the outer skin of the grains to select and extract the powder having a carbon skeleton of plastic properties; and adding phenolic vegetable oil and charcoal powder obtained in the cashew production process to the carbon powder And a mixture generation step of mixing the mixture (S222); and a polymer generation step (S223) of adding citric acid to the mixture and heating the polymer material formed by the citric acid to generate a polymer.

The carbon powder extracting step (S221) is a process of selecting and extracting powder having a carbon skeleton of a plastic property after crushing the outer skin of the grain, wherein the grain is not limited to any one, but according to a preferred embodiment of the present invention It is most preferable to use a shell of pine nuts and chestnuts in which this hard and smooth powder having a carbon-based carbon skeleton can be extracted in large quantities. In this regard it can be confirmed in Example 2 below.

Below, the extraction amount of carbon powder according to the types of grains and the grains most similar to those of other plastics were analyzed and compared.

The grains used in the experiments include by-products of chestnuts and pine nuts proposed by the present invention, as well as by-products of rice bran and corn, which are mainly used by manufacturers of vegetable plastics.

<Comparison Table of Properties of Plastics by Cereal By-products>

In the present invention, as shown in Table 2, the plastic properties of the natural synthetic resin prepared using carbon powder extracted from by-products of chestnut, pine nuts, bran, and corn under the condition that 100% pure plastic properties were analyzed.

As can be seen from Table 2, the by-products of chestnut showed the highest similarity in properties such as strength, hardness, insulation, insulation, stability, elasticity, and buffering under 100% of plastic properties. Similarities were shown in order of chaff.

In particular, chestnut by-products showed the highest carbon powder extraction rate of 68.72%, so that a large amount of carbon powder could be extracted even with small by-products, whereas bran and corn were 28.14% and 39.10%, respectively. Could.

As a result, it is most preferable to use by-products of chestnuts or by-products of pine nuts to extract the carbon powder of plastic properties.

The mixture generation step (S222) refers to a process of mixing the polymerization catalyst and the charcoal powder to the carbon powder. Herein, the polymerization catalyst refers to a novel natural coating agent that is manufactured similarly to the natural lacquer component structure and has excellent mechanical properties as well as rust prevention, moisture proofing, electrical insulation, and chemical resistance, and is harmless to the human body. In particular, the present invention used a phenol-based vegetable oil that can be obtained in the production process of cashew nut away from the conventional method using formalin, an environmental pollutant.

Cashew nut oil (CNSL), on the other hand, contains anacardic acid (60-65%), cardol (15-20%), cardanol (10%) and some methylcardol during the extraction process. Phenolic derivatives of cardol cause CNSL's vesicant activity and toxicity. And the method of extracting the CNSL can be divided into solvent extraction method and technical extraction method, in the present invention, when the technical extraction method using methanol and ammonia, cardol recovery is easier to use the technical extraction method.

In addition, the above-mentioned charcoal powder basically removes the smell of carbon powder and cashew nut oil, and also exhibits a moisture removal function, thereby preventing condensation that may easily occur when using agricultural facilities.

The polymer generation step (S223) is a process of adding a citric acid to the mixture, and heating the polymer material formed by the citric acid to generate a polymer. That is, as charcoal added to the mixture is ignited in the process of heating the polymer material formed by citric acid, the mechanical properties of the weight are improved.

In this case, the improvement of the mechanical properties includes the effect of preventing the crazing property of the plastic material being severely deformed locally in the narrow region of the wedge shape when subjected to tensile stress or bending, and its excellent water absorption rate, so that the glass transition temperature, yield stress, It refers to the effect of reducing the hygroscopic property of lowering the elastic modulus.

The above flame retardant material generation step (S230) is a process for imparting flame retardancy to the air cap, and consists of pulverizing the powder of 0.5 ~ 0.8㎛ size the same as the main material after drying the flame retardant compound, the binder and the diluent.

The above flame retardant compound is a mixture of high molecular chlorinated polyethylene powder, inorganic aluminum hydroxide powder and zinc borate powder. The above materials are fire resistant and have excellent functions without the occurrence of toxic substances such as carcinogens during combustion. .

The binder refers to a binder compound in which AW-101-50, which is an acrylic binder, PolySol, which is a water-soluble acrylic binder, and Michel, a natural organic fiber (CMC) binder.

In addition, the diluent is an isolated microorganism of a species deposited under ATCC Accession No. PTA-10208, and refers to the total fatty acid produced by the microorganism with at least about 10% by weight of icosapentaenoic acid and distilled water extracted two or three times with hydrothermal extraction.

The flame retardant material of the present invention composed of the aforementioned material is preferably composed of 40 to 50% by weight of the flame retardant compound, 40 to 45% by weight of the binder, and 10 to 15% by weight of the diluent. For example, if the flame retardant compound is less than 40% by weight, it is difficult to find the effect of the flame retardant function only by increasing the manufacturing cost. On the contrary, when the flame retardant compound exceeds 50% by weight, the heat cap, light resistance and weather resistance of the air cap are remarkably increased. It implies a reduced problem.

The flame retardant material adding step (S240) refers to a step of injecting the molten main material and the natural synthetic resin into the molding machine and then adding the flame retardant material to form the air cap, and the flame retardant material is the main material and the natural synthetic resin in the molding machine. Apply a uniform amount evenly to the front of the air cap before solidifying.

The above insulation material bonding step (S300) is a process of applying a natural adhesive to both sides of the air cap to integrate with the insulation material, in particular, the air ball formed in the air cap is positioned to be alternately placed in a separate space formed in the insulation material The air layer of the cap can be maintained.

For example, the auxiliary film laminated on the air cap is bonded using a natural adhesive prepared by mixing the natural ingredients extracted from rosin, garlic and kelp, sodium alginate and distilled water, the present invention proposes a method for producing a natural adhesive Same as 3.

1. Prepare 20-40 wt% of rosin powder, 10-15 wt% of garlic, 10-15 wt% of kelp, 25-30 wt% of sodium alginate, and 15-20 wt% of distilled water.
