Manufacturing Method and Structure of Soundproofing Layer of Alternation Timber Using Wasted Plastic}

The present invention relates to a method of manufacturing a replacement wood soundproof board using waste plastic and a soundproof board structure.

In general, the soundproof plate constituting the soundproof wall has a sound-absorbing effect by absorbing the surrounding noise by assembling the sound-absorbing member between the front plate formed with various types of sound-absorbing holes on the front surface and the back plate bent in a predetermined shape. .

In recent years, sound barriers made of soundproof panels have been developed in a way that harmonizes with the surrounding environment and creates an aesthetic sense. Especially, sound barriers installed around schools, houses, apartments, rivers, beaches, and mountainous areas are suitable for these nature and buildings. It is required to have a color to have a useful value as a sculpture other than the soundproofing effect.

In order to meet these demands, conventional sound insulation boards are manufactured by forming a thin plate made of aluminum plate or iron plate in a certain shape in order to maintain its strength, and then assembling the front plate and the back plate, Paint is applied to the soundproof panel by spraying paint.

Such a conventional color soundproofing board and a general soundproofing board are very ugly in appearance due to deformation and peeling of the painted color on the surface due to wind pressure, ambient climate and impact when left installed for a long time. .

In view of this point, in recent years, there is an attempt to provide a soundproof wall using wood to suit the surrounding environment. However, in Korea, most of the wood is imported, especially in Korea, so the cost of installing soundproof walls using wood is excessive, and the abrasion, weather resistance, hardness, shear force, tensile strength and compressive strength are weak. Because of its weak waterproofness, the appearance of the soundproof wall is beautiful, but the function of the soundproof wall is deteriorated.

The present invention is intended to provide a soundproof plate having a durable, durable appearance without having to change the appearance of wood to reduce the installation cost of the soundproof wall and increase the scratch and blocking effect.

In the present invention, the outer layer is a non-foaming layer and the inner layer is a foaming layer, but the outer layer has a wood pattern layer, and the inner layer is a technical task of absorbing noise.

In order to achieve the above object, the present invention pulverizes a waste synthetic resin (waste plastic) such as PS (polystyrene) or PP (polypropylene) or PE (polyethylene) to extrude and mold through an extruder and a mold. At the same time as foaming and foaming, the outer layer is non-foamed while adhering and conveying the surface of the foamed layer and the surface of the non-foamed layer, and quenching and pulling the transferred foamed and non-foamed layer to a certain shape through sizing. Then it is heated and coated with a pattern transfer (or painting process) or pattern sound on the outer surface of the non-foaming layer. In another aspect, the present invention is characterized by mixing the waste wood powder in the vPf synthetic resin and extrusion molding to increase the processability.

The present invention is pulverized waste synthetic resin, such as PS or PP or PE, and then mixed with an appropriate amount of blowing agent, accelerator, stabilizer, oxidizing agent, pigment, extruded, molded through an extruder and a mold, and the PS or at the same time to form the inner layer by the foaming machine. A suitable amount of sunscreen is mixed with waste synthetic resin such as PP or PE, and extruded through an extruder and a mold to have an outer layer of a non-foaming layer, and the surface of the foam layer and the surface of the non-foaming layer are adhered and transported. Rapidly cool the foamed and non-foamed layer to a certain shape through sizing, draw it out, heat it, and give the shape and color of the wood by pattern transfer (or painting) or pattern yin / emboss on the outer surface of the non-foamed layer. In addition, a hole having an opening ratio of about 25% is formed in the non-foaming layer, which is the outer layer, so that external noise is absorbed into the foam layer. In addition, the foam layer is provided on the surface of the sound-absorbing material by adhering the sound absorbing material to provide a more sound-absorbing effect, one side of the sound-proof plate to put the fitting projections on the other side to facilitate the assembly of the soundproof plate.

This invention will be described in detail with reference to Examples.

(Example)

Pulverized waste synthetic resin such as PS or PP or PE, and then mixed with the waste synthetic resin by 0.1% by weight of blowing agent, accelerator, stabilizer, oxidizing agent and pigment, respectively, are extruded, molded or The waste synthetic resin and the wood powder are mixed at 70:30, extruded and molded, and the inner layer 4 is foamed by the foaming machine 3, and then spunized, and the waste synthetic resin such as PS or PP or PE is pulverized. 0.1% weight of the sunscreen is mixed with the waste synthetic resin and extruded through the extruder 5 and the mold 2 to have the outer layer 6 of the non-foaming layer, and the surface and outer layer of the inner layer 4 ( The surface of 6) is glued and conveyed, the conveyed inner layer 4 and outer layer 6 are quenched while being finished in a predetermined shape through the sizing 7, drawn out by the drawer 8, and then heated. Heating treatment by (9) and pattern transfer (or painting treatment) on the outer surface of the outer layer (6) By the pattern sound / raised to produce a sound insulation board (A) to give it the shape and color of the timber. In the non-foaming layer, which is the outer layer 6, holes 6 'having an opening ratio of about 25% are formed during molding so that external noise is absorbed by the inner layer 4, which is a foam layer. In addition, the soundproof plate (A) for adhering the sound absorbing material (10) to the surface of the inner layer (4) that is the foam layer to have a more sound-absorbing effect, one side of the soundproof plate (A) is fitted projection (A ') The other side has a fitting recess A "to facilitate the assembly of the sound insulation board A. The sound absorbing material 10 may be used depending on the degree of sound absorption, and thus is not an essential configuration of the present invention. In order to increase the processability in any form, such as lumber, when manufacturing the soundproof plate, the ratio of the waste synthetic resin and the wood powder is 70: 30, extruded and molded, and the inner and outer layers (4) and (6) are formed as described above.

The soundproof plate (A) of the present invention manufactured as described above is made of a synthetic resin having an outer layer (6) and a non-foaming layer (6), and is mixed with an ultraviolet ray blocking material to have a solid and noise-blocking effect as well as to be discolored by sunlight. As it is resistant to moisture and non-toxic, it is environmentally friendly and can be stored for a long time, and the inner layer 4 has a foam layer, so that the sound absorption is easy and the non-foaming layer and the foam layer are in a state of being light. It is easy to transport and install the soundproof wall, and it is possible to transfer and sound / emboss wood-like patterns on the outer layer 6 to provide a natural soundproof wall like wood, and the soundproof plate A is fitted to make the soundproof wall It is easy to install.

On the other hand, the present invention is limited to the soundproofing plate (A), but according to the molding aspect, using a waste synthetic resin, a heat insulating material or a sound absorbing member (B) having an outer layer (6) that is a non-foaming layer and an inner layer (4) that is a foaming layer (B). ) Can be produced by the present invention,

The present invention provides a soundproof wall by making a soundproof plate having a foamed layer and a non-foamed layer to give a light and solid and the appearance in the shape and color of wood, by using a waste synthetic resin, the inner layer and the outer layer as an integral In addition to reducing manufacturing costs, it is light and easy to assemble, which helps to reduce installation costs, and protects it from ambient weather and sunlight, allowing long-term storage without discoloration. Has an effect.
