Description

ECO FRIENDLY LIQUID STATED WALL PAPER COMPOSITION HAVING A FUNCTION OF NON-INFLAMMABLE AND INSULATION}

The present invention relates to an eco-friendly non-combustible heat insulating liquid wallpaper, and more particularly, to an eco-friendly non-combustible heat insulating liquid wallpaper that provides weather resistance by imparting water repellency and antibacterial properties and strengthening binding properties.

One of the most important elements in our daily life is the residential environment centered on the housing. The residential environment is diversified not only in residential homes but also in offices, sales places, and various accommodations.

Various interior materials are inevitably applied to the construction of such residential facilities, and wood interior materials such as cement-based walls and plywood made of various woods, wallpaper, textile materials, paints, etc. are applied. Some raw materials are used as raw materials for the materials, but by using a substantial portion of them as synthetic materials to improve durability, it is found that various harmful substances are released to adversely affect the human body.

In particular, interior materials that are applied to residential spaces where people live and rest for a long time have a close impact on the environment. So far, cement walls or formalin-detected plywood, formalin-containing grass, and organic solvents Since the interior environment is mostly used to decorate and finish the indoor environment using exposed plastering wallpaper, such interior materials inevitably release harmful substances and dominate most residential environments such as living rooms or homes.

These indoor harmful environments include respiratory diseases (cold, asthma, etc.) and skin diseases (atopic dermatitis, rashes, etc.) caused by organic solvents or formalin, and are most severe in newly decorated homes and offices. An incompetent guest, "SICK HOUSE SYNDROME," coined the phrase.

Due to such a phenomenon, recently, a wallpaper form in which a wall is finished in the form of painting a liquid directly on the wall has been disclosed.

Related technologies include, for example, registered patent No. 004088, registered patent No. 1138128, and the like.

By the way, the liquid wallpaper is poor in insulation and fire resistance, and because it is directly painted on the wall was not environmentally friendly in terms of hazard.

Particularly, in the case of registered patent No.0406288, only the functional composition related to the removal of toxicity is disclosed, which is irrelevant to heat insulation and fire resistance, and in the case of Registered Patent No.0406288, the construction time is shortened through rapid drying and the adhesion of the loess is increased. Only compositions for the expression of intrinsic function have been disclosed and this also has nothing to do with the thermal insulation, fire resistance, antifungal properties of the present invention.

In addition, as a result of requesting the Gyeonggi Northern Intellectual Property Center of Gyeonggi North Chamber of Commerce and Industry in order to confirm the prior art with respect to the present invention, according to the report dated September 24, 2012, Patent No. 1168010, Patent No. 0994787, etc. It was confirmed by peripheral technology.

However, Patent No. 1168010 is a panel that is cut to a certain size using a press or a mold, and it is described in the report that no similarity is found except that it contains some diatomaceous earth. It is not related to wallpaper, but it has been found that there is no similarity except that it contains starch system as diatomaceous earth and thickener.

As such, the concept of the liquid wallpaper related to the present invention is in an early stage of development. Since the technology is not matured, the surrounding technology or the bottom technology is very poor, and thus the need for protection for the technology preemption is recognized.

The present invention has been made in consideration of the prior art level as described above and confirmed to be protected, A material mixed with a non-combustible binder sodium silicate and an acrylic composition (acryl monomer) having a coating property, and heat insulating properties Its main purpose is to provide environmentally friendly non-combustible insulating liquid wallpaper that can increase the non-flammability and thermal insulation while having environmentally friendly, excellent adhesiveness by forming a B material having a certain ratio.

In addition, the present invention has a further object to further increase the longevity of the A, B mixture by inhibiting the development of mold, and further comprises a C material that blocks the decay to prevent mold form and decay.

The present invention as a means for achieving the above object, as a composition constituting an environment-friendly non-combustible insulating liquid wallpaper, A mixed with 10-20% by weight Yttria, 20-30% by weight acrylic monomer and the remaining sodium silicate matter; Silica powder 5-10% by weight, bentonite 5-10% by weight, diatomaceous earth 5-10% by weight, talc 5-10% by weight, titanium dioxide 5-10% by weight, starch paste 15-20% by weight, wood powder 30-60 It includes; B material mixed by weight%, and provides an environmentally friendly non-flammable insulating liquid wallpaper, characterized in that the mixed composition A and B material in a weight ratio of 7: 3 to 6: 4.

At this time, with respect to 100 parts by weight of the liquid wallpaper composition mixed with the A material and the B material, 20-30 parts by weight of the C material is further added to increase mold prevention and antiseptic properties, wherein the C material is sodium benzoate (Sodium Benzoate) 5-10% by weight, quaternary ammonium compound (Quaternary ammonium compound) 1 to 14% by weight, phenol derivatives (Phenol derivative) 1 to 3% by weight and the remaining water is also characterized.

In addition, wood flour constituting the B material is characterized in that the fine powder having a uniform particle shape of 200 mesh (74㎛) by grinding pine or cottonwood.

According to the present invention, it is possible to implement environmentally friendly in the field of liquid wallpaper, to improve the heat insulation, to ensure non-flammability and flame retardancy is to strengthen the fire resistance, to prevent the occurrence of mold and decay can achieve a long life.

Hereinafter, preferred embodiments according to the present invention will be described in detail.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, the embodiments in accordance with the concept of the present invention may add various changes and may have various forms, but this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, the spirit and technology of the present invention It is to be understood that all changes, equivalents, and substitutes included in the scope are included.

The present invention relates to a composition constituting a liquid wallpaper, that is, a kind of paint composition, the liquid wallpaper refers to the form of wallpaper to finish the wall in the form of painting the paint directly on the wall as described above.

In particular, the present invention is a liquid wallpaper by solving the problems such as the limit of the existing liquid wallpaper, that is, paint form, heat insulation, fire resistance, and mold problems caused by repetition of condensation due to temperature differences, shortening the lifespan due to corruption It is a new creation to open up a new type of market.

To this end, the liquid wallpaper according to the invention is constructed as follows.

That is, A material mixed with 10-20% by weight of Yttria, 20-30% by weight of acrylic monomer and the remaining sodium silicate; Silica powder 5-10% by weight, bentonite 5-10% by weight, diatomaceous earth 5-10% by weight, talc 5-10% by weight, titanium dioxide 5-10% by weight, starch paste 15-20% by weight, wood powder 30-60 B material mixed in a weight%; is a coating composition prepared by mixing in a weight ratio of 7: 3 to 6: 4.

In addition, for antifungal and antiseptic properties, 5-10% by weight of sodium benzoate, 1-14% by weight of quaternary ammonium compound, 1-3% by weight of phenol derivative and remaining water Consisting of the C material may be further added to the A, B mixture 20-30 parts by weight based on 100 parts by weight of the A, B mixture.

At this time, the composition ratio constituting the liquid wallpaper composition is formulated to satisfy all the following four conditions required by the alloy screening criteria.

That is, according to the alloy screening criteria, the composition ratio of the composition should not be ① the sum of the maximum amounts of all components is less than 100%, ② the sum of the minimum amounts of all components should not exceed 100%, ③ the composition of any one component The sum of the maximum amount and the minimum amount of the remaining components should not exceed 100%. (4) It is required that the sum of the minimum amount of any one component and the maximum amount of the remaining components not reach 100%. It can be seen that satisfies all of these conditions.

Hereinafter, the reason for limiting the composition ratio of the said composition is demonstrated.

First, the A material is to implement a non-flammable, flame retardant function, the B material is added to implement a heat insulation and environmentally friendly function.

At this time, the yttria has an excellent hot stability at high temperature, has a very low thermal conductivity, and has a very high resistance to thermal shock and is added for fire reinforcement.

Such yttria is reinforcing fire resistance, that is, fire retardant function because of the excellent thermal barrier function, in the present invention should be added to be limited to 10-20% by weight, if less than 10% by weight of the fire reinforcement reinforcement drops sharply, If it exceeds 20% by weight, the dispersibility and coating properties deteriorate, so it should be limited to the above range.

In addition, the acrylic monomer is to act as a coating agent by increasing the room temperature stability to enhance the adhesion. In addition, it lowers the freezing temperature of sodium silicate to enhance the function as wallpaper.

Therefore, in the present invention, it should be added to be limited to 20-30% by weight, it is difficult to perform the function as a wallpaper when the adhesion strength is lowered when added to less than 20% by weight, since more than 30% by weight, the viscosity is increased and the applicability worsens It should be limited to the above range.

In addition, the sodium silicate is a main component constituting the A material, and is added to implement nonflammability and flame retardancy.

Such sodium silicate generally refers to liquid sodium silicate, and is mainly known as water glass.

When the sodium silicate reacts with the metal ions contained in the composition of the present invention at the time of exotherm due to a fire or the like, it forms a film while gelling, and the non-flammability and flame retardancy are increased by the film.

Therefore, in order to further increase the effect, it is possible to mix the material capable of eluting metal ions together in an aqueous solution state while being decomposed at a specific temperature, for example, an initial exothermic temperature in a fire.

At this time, the preferred metal ions may be Ca, Mg, Al, Ba, etc., since these metal ions are gelled while producing insoluble silicate metal hydrate or silicate metal hydroxide while polymerizing with silicate ions.

On the other hand, the B material is added to the thermal insulation and environmental friendliness, of which bentonite is expandable clay, the silica powder is flame retardant, quencher, diatomaceous earth is responsible for the insulation and air cleaning, deodorizing function.

And talc adjusts volume as a white pigment, and titanium dioxide is also used as a pigment.

In addition, starch grass performs a natural thickener and adhesive function, wood flour performs a heat insulation enhancement, absorption, sound absorption function.

At this time, when bentonite is added in an amount less than 5% by weight, the adsorption property is lowered. If it is more than 10% by weight, ion exchangeability and swelling property are increased so that the volume is increased to decrease the physical properties.

In addition, the silicone powder is a substance that intensifies flame retardancy and increases water resistance through a powder curing function, and induces quenching to express the color of the pigment itself. It is preferable to add in the range.

In addition, since diatomaceous earth contains a myriad of pores enough to absorb a liquid up to five times its volume, it performs deodorization and air cleaning functions, and is preferably mixed with bentonite, which is a clay component, in the same ratio.

In addition, the talc and titanium dioxide is used as a pigment, it is preferably added in 5-10% by weight in consideration of the relationship with other components.

In addition, starch paste is a natural eco-friendly adhesive for maintaining the state of the liquid wallpaper of the present invention is firmly applied to the wall by enhancing the adhesion by enhancing the adhesion, when less than 15% by weight, the adhesive strength is lowered, 20% by weight If it exceeds, viscosity becomes large and applicability worsens and it should limit to the said range.

In addition, wood flour should be selected from pine and cottonwood, and 200 mesh (74㎛) fine granular powder made of wood alone should be used by grinding cottonwood powder suitable for maintaining workability and whiteness. This wood powder is a cellulose material obtained from nature, and it reduces friction with the compounding composition to solve problems such as curling and bending, and improves the thermal stability of the surface of the table, that is, heat resistance and strength, and it is a natural material. It is possible to construct a breathable liquid wallpaper that keeps fine pores adequately and ensures breathability.

To this end, in the present invention is added as a main component constituting the B material, it should be added limited to the range of 30-60% by weight.

In addition, the A material and the B material should be mixed in a weight ratio of 7: 3 to 6: 4 in order to enhance flame retardancy and nonflammability.

If the content of B substance is added more out of the above range, the insulation and eco-friendliness will be increased, but the flame retardancy and non-combustibility and fire resistance are poor, which is vulnerable to fire, and if the A substance is added in excess of the above range, Lack of adhesion prevents it from functioning as a liquid wallpaper.

Therefore, these mixtures must be mixed in the above range, and other functional materials may be further added in a certain part by weight based on 100 parts by weight of the mixed A and B mixtures.

For example, 20-30 parts by weight of a C substance for enhancing antifungal function and antiseptic properties may be added. Among the components constituting the C substance, sodium benzoate is added to increase the antiseptic property and includes caffeine. Therefore, it should be added within the range of 5-10% by weight.

In addition, quaternary ammonium (quaternary ammonium salt) is a kind of cationic surfactant in the form of a salt, a compound mainly used as a cleaning agent, used for plaque suppression and antibacterial effect, and may be added in less than 1% by weight in the present invention. When the anti-fungal and antimicrobial effect is sharply lowered, and if it exceeds 14% by weight, the antifouling property is sharply increased to weaken the binding of the subsequent layer should be added in the above range.

In addition, the phenol derivative is a cleaning agent that performs a kind of disinfection function, in addition to the cleaning function in the present invention is added to improve the adhesion of the coating, that is, the layer. To this end, it should be added in the range of 1-3% by weight, but if added in less than 1% by weight it is difficult to expect the cleaning effect, if it exceeds 3% by weight should be limited to the above range because of the risk of concern.

The liquid wallpaper according to the present invention having such a composition replaces the existing paper wallpaper by being applied to the interior wall, but creates a new concept wallpaper culture having excellent heat insulation, fire resistance, fire resistance, waterproofness, nonflammability, and eco-friendliness compared to the existing paper wallpaper. It is expected to be possible.

Hereinafter, examples will be described.
