Description

Soundproof Panels {The panel to take soundproof functional}

The present invention relates to a thermal insulation and soundproofing plate for building, and more specifically, to waterproof, constructability, and the like formed of a mixture of a high-weight polyester nonwoven fabric having excellent tensile strength and mechanical properties, an acrylic polymer emulsion, Portland cement, quicklime or slaked lime, etc. The present invention relates to a plate member provided with a reinforcing material (core material) at regular intervals between upper and lower fiberboards having excellent processability and durability, and an inner insulation layer for insulation and sound insulation.

The indoor noise of apartment houses is caused by the weight reduction of the structure and the operation of the mechanical equipment due to the high rise, and the vibration and noise generated by the forcible force of the mechanical equipment are transmitted to the interior of the house by the pipes and the structure, which causes enormous damage to life. The concrete used in most apartment houses in Korea is heavy and dense due to the characteristics of the material, so it is better to block the noise transmitted through the air such as speech or TV sound than other materials of the same thickness. However, due to the characteristics of the material, the impact sound (solid transmission sound) generated by direct impact on the concrete surface has a characteristic of being easily transmitted to the adjacent generation.

These characteristics are often experienced by people living in multi-family houses, and the most common ones are the sound of running upstairs and dropping things, and is a major source of noise that is annoying even if the frequency of occurrence is not high.

The measures to improve the sound insulation performance for the floor impact sound reduction currently being constructed include the use of a flexible floor finish that changes the characteristics of the impact source, and the second floor structure that prevents or transmits the impact energy to the structure as much as possible. (floating floor) or the use of a resilient mat, to prevent the floor from vibrating against the third impact to increase or increase the rigidity of the floor slab, to block the sound reflected from the fourth floor slab, etc. In order to improve the ceiling structure of the lower layer for the purpose of the present. Increasing the thickness of the floor slab increases the floor density and stiffness of the floor at the same time, which greatly reduces the impact sound of the floor. When the slab thickness is increased by 10%, the reduction effect is about 2-3dB. In reality, however, it is difficult to increase the thickness or install beams in existing designs, so it is desirable to insulate the ondol components from slabs and walls. Flexible floor finishes, such as carpet and monolium, reduce the impact level of high-end light weights by extending the impact time and lowering the maximum impact force for light impacts. However, it is difficult to expect the effect on heavy impact sounds such as the sound of a child playing, so lowering the spring constant using a flexible material increases the reduction effect. To improve the ceiling structure of the lower floor, the attenuation amount varies greatly depending on the thickness and support conditions of the air layer during the installation of the double ceiling, and the impact sound is amplified when the impact sound is equal to the resonance transmission frequency between the slab and the boards ceiling. Care should be taken as this may cause problems. In recent years, the most frequently implemented method is the sound insulation of the floor structure. However, if the density of the material used is low, cracks may occur on the floor. Also, when the material with high density is used, the sound insulation against impact sound is deteriorated. There was.

The present invention is designed to solve the above problems,

Low-cost building plate that is durable, fireproof, waterproof, and soundproof, and light in weight, allowing direct construction even when constructing concrete slabs or ceilings and walls for soundproofing, and aiming to lighten and strengthen concrete slabs and improve ceiling structures.

In order to achieve the above object, the present invention is based on a high weight polyester nonwoven fabric having excellent chemical stability, solvent resistance, heat resistance, etc., flame retardancy and low molding shrinkage, and its unique miscibility, adhesiveness, water resistance, and alkali resistance. Excellent acryl polymer emulsion, ordinary lime-like portland cement, lime and siliceous raw materials such as silica sand, blast furnace slag and fly ash, and a mixture of a certain amount of foaming agent and admixture diluted in a certain amount are precipitated inside the core substrate, dried, and then formed into a sheet of fiber. It relates to a building plate material formed by adhering insulation (insulation) layers of EPS board, PS board, urethane foam, glass wool, rock wool, mineral wool polyester, etc., which are excellent in sound insulation, sound insulation, heat insulation, and the like.

Hereinafter, the present invention will be described in detail.

In the present invention, the fiber board material of the upper and lower plates 6 and 7 is a siliceous raw material such as general portland cement, a small amount of quicklime or calcined lime, silica powder, and foaming agent in the central substrate 2 of the high-weight polyester nonwoven fabric and the acrylic polymer emulsion. And an inner surface 1 of which the liquid mixture diluted by mixing the admixture or the like is cured by a hydration reaction and the surface finishing layer 3 finished by applying the mixed liquid about once. The core substrate (1), that is, the high-weight polyester nonwoven fabric is manufactured by processing polyester long fibers or short fibers to secure a plurality of pore layers, and thus the inner layer (1), that is, an acrylic polymer emulsion and portland cement, etc. The mixture of diluted components is penetrated and combined with the cured layer to form a rigid configuration. At this time, the strength and weight can be increased or decreased according to the mixing amount of the inorganic portland cement and lime powder, and the inner layer 1 can be simply formed due to the characteristics of the cement hardened by the hydration reaction, Oil resistance, water resistance and chemical resistance makes it waterproof. After the reinforcing material 4 is installed in the upper plate 6 and the lower plate 7 configured as described above at regular intervals, the insulating (insulation) layer 8 for insulation, sound absorption, and sound insulation is configured. At this time, the reinforcing material 4 formed in the fiber boards of the upper and lower plates 6 and 7 has a low density and a function of protecting the insulation layer 8 of a somewhat lower density from the weight of the concrete that is poured in the concrete slab construction. It has a function of preventing the settlement of the bottom caused by the insulation (insulation) layer (8). In addition, the upper and lower plates composed of lime and other inorganic raw materials have a function of further increasing adhesion to concrete due to the concrete and friendly inorganic materials. 6 and 7 are simply a cross-sectional view showing an example of the soundproofing process using the soundproofing panel of the present invention, that is, the construction of the floating floor structure and the structure to improve the ceiling structure.

As described above, the present invention is simply made of inorganic fiber board, reinforcement, and insulation (insulation) layer mainly composed of polyester fiber and acryl polymer emulsion, general portland cement, quicklime, or slaked lime which have excellent durability, tensile strength and mechanical properties. It is not only possible to shorten the air by directly applying during the construction of the floor structure, but also to solve the problems of the conventional floating floor structure, mat type sound insulation floor structure, or double ceiling sound insulation structure, so that it can be utilized as a material for noise prevention of the multi-story construction condition It is possible to achieve the weight reduction and rigidity of the floor concrete slab between each floor of the high-rise housing.
