Description

A melamine foam sound absorbing tile having a surface layer and a method of manufacturing the same

The present invention relates to a melamine foam sound absorbing tile having a surface layer and a construction method thereof, and more particularly, to cut melamine resin foam made of a three-dimensional network structure by foaming melamine resin in a thickness and size according to sound absorbing purpose and various uses. Next, a surface layer having a lattice mesh layer is formed on the surface thereof to improve compressive strength, tensile strength, and durability on the surface of the melamine resin foam having a very poor surface durability.

In addition, this configuration increases the low frequency sound absorption performance in the control and sound absorption of the building sound, and preferably improves the sound absorption performance of the high frequency sound.

Another object of the present invention is to provide a melamine foam sound-absorbing tile having a surface layer capable of forming an interior decoration function by forming various designs on exposed surfaces, and a method of manufacturing the same.

The lack of surface durability thus improves the durability and design of melamine resin foams, which have been limited in use, and thus can be used in a wider range of applications across the construction and industrial sectors.

Melamine resin foam is a soft foam with excellent sound absorption and thermal insulation, and has excellent flexibility, elasticity, and resilience. It is an open-cell structure with fine porosity and excellent flame retardancy (heat stability 240 °, smoke). Density Toxicity Index Oxygen Index Stable in flame propagation tests. It can be used in ultra low temperature (-200 ~ Max.240 °), and it is ultra light (6 ~ 11kg / ㎥) body composed of ultra-fine three-dimensional network structure and does not cause chemical deformation in water and the porosity of resin foam is 90 ~ 95. % And antibacterial properties.

The general supply specification for melamine resin foam is 1250mm × 2500mm × thickness 500 ~ 1000mm. In the present invention, it is used to cut to the standard according to the use and can be cut into a variety of shapes, such as board curved processing uneven processing, cutting and shape processing using a saw blade knife and the like is easy.

However, there are relatively disadvantages to the above excellent characteristics. Ultra-light (6 ~ 11kg / ㎥) body, which has a weak surface durability, which can scratch the surface or generate dust. When used in walls, low ceilings, machinery, industrial facilities, etc. Its use was limited because it was not suitable for maintenance.

Due to these shortcomings, when used as interior sound absorbing interior materials, it is generally used as a backfill sound absorbing material or by attaching synthetic resin sheets or synthetic leather with perforations (porosity of 20 to 35%) to the exposed surface, and also using synthetic fiber fabrics. It was.

In case of using as the back filling sound absorbing material, the perforated sound absorbing method (perforation rate of 15 to 35%) is applied to the ceiling plate or the inner wall of the wall (high density interior board, MDF, metal plate, ceramic embedded board) and used as the back filling sound absorbing material. It was. However, this method has to secure 100 ~ 200mm of the resonance absorption space of the back side, which leads to inefficiency of space utilization.

In addition, the sound insulation system according to the purpose of independent use of space in architectural sound and interior space structure is an important spatial element that must be made like sound absorption. Therefore, it is effective for sound insulation soundproofing as double ceiling and insulated interior wall isolated indoors (non-bearing ceilings and walls that form an isolated interior space using plasterboard or interior boards in concrete slab structure walls facing the outside air in interior construction). Punching or opening a part of the floor to resonate sound absorption is to lower the sound insulation performance.

The open air resonance sound absorption structure enlarges the heating and cooling space, and the convection of the interior can contact the slab and the outer wall, which can lead to condensation and energy loss. This method leads to a waste of 15 to 35% of the double wall, which is useful for thermal insulation, which leads to waste of energy and an inadequate sound absorption structure that partially opens the independent sound insulation space.

The synthetic resin sheet to the synthetic leather is attached to both sides of the adhesive rubber-based adhesive roller or sprayed to dry in the pot life, and finished to meet the required specifications.

Since the use of synthetic resin sheet or synthetic leather is a non-breathable material, the inconvenience caused by the perforation of the sound absorbing purpose (20 to 35% of the porosity used for sound absorption) and the design defect of the perforated surface, the fire of the synthetic resin sheet to the synthetic leather City use is being reduced because it does not comply with the strengthened fire regulations.

The method of attaching the synthetic fiber fabric is prepared by cutting the fabric, applying or spraying the synthetic rubber adhesive on rollers on both sides to adjust the adhesion time (housework time), and attaching and cutting the square corner fabric and folding it to the back side. Formed to dryness.

In this method, the synthetic fiber fabric used is petrochemical synthetic fiber, and harmful gas is generated in case of fire, and when it is used for a long time, the attached fabric is partially peeled and drooped due to repeated expansion and contraction due to the change of temperature and humidity in four seasons. There was a problem.

As the cause of the sagging, the knitting spacing formed during the knitting process of the synthetic fiber fabric is changed and deformed due to the change of temperature and humidity of the four seasons and the living environment, which accumulates on one side of the fabric. In addition, this phenomenon increased with the use of the fiber due to the repeated expansion and expansion of the fiber temperature and humidity.

In order to reduce this problem, when the amount of adhesive used on both sides of the adhesive is increased, the sound-absorbing pores are blocked. Also, since these adhesives are synthetic rubber adhesives, they are more vulnerable to fire in proportion to the increase in the usage amount, The amount of harmful gas generated during a fire increases.

In addition, partial maintenance was not suitable when some parts were contaminated in maintenance.

Due to the problems mentioned above, the use of melamine resin foam is limited and its shape and specification design are not varied.

In order to solve the above technical problem, the melamine foam sound absorbing tile provided with the surface layer of the present invention is

A surface layer having one to a plurality of reinforcing mesh laminates;

An inner sound-absorbing layer composed of a melamine resin foam having a light weight (6 to 11 kg / m < 3 >) and made of an open-cell having a minute pore size; This is made up.

The surface layer should be a sound absorbing surface layer that is suitable as an interior finishing material for indoor construction because it has excellent surface strength and impact resistance, abrasion resistance, sound absorption, sound control, various new design expressions, multifunctional decoration sound absorption tiles, and fireproof safety. .

The surface layer has a reinforcing mesh laminated layer in the surface layer, and a finish layer is formed on the surface of the melamine resin foam using the sound absorbing paint or the sound absorbing putty.

The surface layer is one or more of the sound-absorbing paint or sound-absorbing material selected from the group consisting of one or more layers of reinforcing mesh layers laminated on the surface of the inner sound-absorbing layer (melamine resin foam) and the sound-absorbing paint or sound-absorbing putty. It is characterized by a melamine foam sound-absorbing tile applied to form a surface layer.

Wherein the surface layer is formed by laminating a reinforcing mesh layer on the surface of the inner sound-absorbing layer (melamine resin foam) in one to many layers and applying at least one sound-absorbing paint or sound-absorbing putty selected from the group consisting of a sound- To form a surface laminate, characterized by a method for on-site construction of a melamine foam sound-absorbing tile.

In the surface layer, the reinforcing mesh laminate is characterized by a melamine foam sound-absorbing tile which can be composed of one to several layers.

In the surface layer, the reinforcing mesh laminate is characterized by a melamine foam sound-absorbing tile that can be confined to one, or more than one, of the upper, middle, and lower surfaces of the surface layer.

For the purpose of configuring the reinforcing mesh lamination with one or more layers, the compressive strength, durability, and tensile strength are increased and the planar horizontality is improved as the lamination quantity increases. In addition, decorating means for expressing the texture or shape according to the thickness, shape, and material (fiberglass mesh, synthetic fiber mesh, natural fiber mesh, carbon fiber mesh, metal mesh) And also provides a design means for expressing a part of the overlapping shape in a clear manner.

Thus, the lamination of the reinforcing mesh may be composed of one to several layers, and preferably one to three layers.

The structure of the surface layer having the reinforcing mesh lamination can be installed on the upper surface, the side, and the lower surface of the melamine resin foam, and the thickness of the surface layer is characterized by the melamine foam sound absorption tile composed of 1 ~ 7mm.

The reinforcing mesh lamination on the surface of the inner sound-absorbing layer may be provided on the upper surface, the side surface, and the lower surface of the melamine resin foam, but may be selectively limited to one surface depending on the application.

In the present invention, the term "surface layer" is used to describe a melamine foam sound-absorbing tile and is a surface layer having a thickness of 1 to 7 mm provided on the inner sound-absorbing layer (melamine resin foam) Quot; refers to a surface layer comprising a laminate of mesh layers of one to several layers.

The surface layer is a surface layer including a reinforcing mesh laminate and has a thickness of 1 to 7 mm. If the thickness of the surface layer is less than 1 mm, surface strength and durability are insufficient, and low frequency sound absorption performance is inadequate. When it is 7 mm or more, the drying time is increased and the weight is increased excessively. Therefore, it is suitably 2mm-5mm.

In the surface layer, the layer in which the reinforcing mesh is located may also be formed on the lower surface of the melamine resin foam. It is attached to the bottom surface of the melamine resin foam, and at least one of the sound absorbing paint or sound absorbing material selected from the group consisting of sound absorbing paint or sound absorbing putty is applied to the bottom surface of the melamine resin foam by applying a thickness of 1 to 7 mm to the reinforcing mesh surface.

Such a configuration may be insufficient in the case of limiting the surface layer to one surface, and increases the planar smoothness of the melamine foam sound absorbing tile, reduces the deformation of the plane, and enhances the compressive strength, tensile strength, and durability. In addition, the melamine foam sound-absorbing tile is applied to the wall surface to increase the adhesive strength and improve the durability, it is easy to use the general tile adhesive or tile bond and workability is improved.

The use of the term reinforcing mesh herein refers to the use of the term " strengthening " of a reinforcement mesh (netting, netting) The present invention will be described with reference to FIG.

In the planar material of the surface layer using the reinforcing mesh, the thickness of the surface layer can be preferably adjusted according to the respective mesh cross-sectional thickness according to the reinforcing mesh material and the thickness. It is used as a material for forming a frame, and in the subsequent sound-absorbing paint or sound-absorbing putty process, it functions as a frame having a flat structure that uniformly supports the laying pressure of the laying tool and the laying press plate, thereby forming a uniform thickness and plane. .

The cross-sectional thickness of the material constituting the reinforcing mesh varies, and in the case of natural fibers, the thickness of the fiber produced in related industries is approximately 0.1 mm to 3 mm, and in the case of metal wires, approximately 0.1 mm to 1 mm. However, the thickness of these fibers can be custom-made to the thickness as required and suitable thickness of the present invention is 0.1mm ~ 3mm.

In the case of the metal material mesh, the metal mesh manufactured in the plane is passed through a press roller designed in an uneven shape to produce a uneven shape three-dimensional mesh. In the present invention, the production of such a three-dimensional metal mesh may be manufactured according to the purpose of use, and the thickness of the metal mesh suitable for the surface layer is 2 mm to 7 mm, more preferably 3 mm to 5 mm.

In case of less than 2mm, three-dimensional shape representation is inadequate. In case of more than 7mm, it is too rough.

Natural fibers are also environmentally safe and also suitable for producing natural textures on exposed surfaces.

The expression of the natural texture is to apply the sound-absorbing putty to the sound-absorbing paint on the surface of the inner sound-absorbing layer in the process of forming the surface layer, to maintain the horizontal level before the drying step and attach the natural fiber mesh. Subsequently, it adheres to natural fiber mesh network using tools such as paint brush, brush, plastic, plastering trowel horizontal roller, and compresses (sweeps) in a certain direction so that mesh network can be adhered, leveled and embedded of fiber The control was repeated. Therefore, the natural fiber mesh net thickness, mesh spacing, texture and color according to each kind of natural fiber were differentiated, and it was suitable as a decorative sound absorbing tile finishing material.

In addition, in the tissue structure that can be used as a reinforcing mesh, a mesh fabric (coarse woven fabric like a net) having a weaving spacing (the inner diameter of the lattice spacing) of 0.5mm or more and less than 10mm can be used. Fabrics, synthetic fiber fabrics, glass fiber fabrics, mineral fiber fabrics, carbon fiber fabrics are available. In consideration of fire safety, nonflammable fabrics and flameproof fabrics are suitable. Therefore, the 'reinforcing mesh' of the present invention may include the mesh fabric or the fiber fabric.

In the reinforcing mesh, the size of the mesh scale usable in the present invention is 0.5 to 10 mm in diameter and suitably 1.5 to 5 mm. If it is smaller than 1.5 mm, the adhesive property is insufficient and it is not suitable for a sound absorption structure. When it is larger than 5 mm, the reinforcing performance is insufficient. Reinforcing mesh having a scale of 5 mm or more is suitable for the case of reinforcing mesh lamination in double to triple.

In the surface layer, the reinforcing mesh lamination is also provided with a melamine foam sound-absorbing tile that can be provided on the upper exposed surface and the middle sub-layer on the surface layer cross-section and its construction method.
