The present invention relates to a method for manufacturing a sound insulation and insulation material using expandable polystyrene (hereinafter referred to as EPS) aggregate, and more specifically, a polypropylene fiber and a high performance water reducing agent are added to cement and stirred EPS aggregate. By inserting it into mold and compacting it by vibratory compression, and solidifying it, greatly improving compressive strength, sound absorption and insulation, and making soundproofing and insulating material that can create soundproofing and insulating effect with a single material. It relates to a soundproofing and insulating material manufacturing method.

In general, the thermal insulation of the building material is preferably a small thermal conductivity of the material itself, but most of the thermal conductivity is not so small. Therefore, in most cases, it is made to be porous in order to reduce the thermal conductivity to take advantage of the thermal insulation of air in the pores. Typically used as a heat insulating material is a foamed polystyrene material called styrofoam.

The styrofoam is manufactured in the form of a panel and is widely used for insulation of interior and exterior walls of buildings, and it is used as a relatively excellent insulation material because it contains bubbles.

However, when constructing a building, sound insulation is required along with the insulation of each floor or each room, and sound insulation between the building and the outside is also required. In particular, in the case of buildings adjacent to roads or factories, sound insulation performance is required along with insulation. In this case, if styrofoam is used as insulation, the use of panels of sound insulation materials is required separately.

As mentioned above, separate sound insulation and insulation materials are required to achieve two purposes, soundproofing and insulation, and as mentioned above, the soundproofing and insulation of each floor and room, and the soundproofing and insulation of the building and the surroundings of the building are considered. Naturally, a large quantity of materials are required for construction.

This is due to the problem that the material that achieves sound insulation and the material that achieves insulation have separate and independent structures for each purpose.

Accordingly, the development of a single material that is soundproofed and insulated at the same time is progressing. A typical example is a panel that includes styrofoam in concrete to contribute to sound insulation in concrete and styrofoam to insulate.

The conventional soundproofing and heat insulating materials as described above are made to a certain degree of sound insulation and heat insulation even using a single panel material, it has been reduced the factor of enormous material waste compared to the existing using a separate sound insulation or heat insulating material.

By the way, the conventional sound insulation and heat insulating material has a structure that includes a concrete and styrofoam, there is a problem that the concrete is limited in the role of sound insulation. In addition, since the styrofoam is not embedded throughout, but mixed with concrete, there is a problem in that the insulation effect is limited.

Therefore, the present invention has been made in view of the above-described conventional problems, the first object of the present invention provides a method for manufacturing soundproofing and insulating materials for civil engineering and construction that can produce a soundproofing and insulating material at the same time when used as a product. It is.

And a second object of the present invention is to provide a method for producing soundproofing and insulating materials for civil and construction, including a stirring process of polypropylene fibers that can contribute to complement the soundproofing and insulating functions when used as a product.

The object of the present invention, in the soundproofing and thermal insulation material manufacturing method using EPS aggregate, 60.70 to 62.0% by weight of cement and 11.0 to 12.0% by weight of the EPS aggregate and stirring for 1 to 2 minutes ( S1000);

Injecting 0.2 to 0.3% by weight of polypropylene fiber and stirring for 1 to 2 minutes (S2000);

Adding 25.70 to 27.0% by weight of water and stirring for 1 to 2 minutes (S3000);

Step into the mold and compacted by vibrating compression (S4000); And

Solidifying by drying and leaving the mold (S5000); is achieved by a method for manufacturing soundproofing and insulation materials for civil and building comprising a.

Here, after the addition and stirring of water, a high performance water reducing agent including naphthalene and maleic anhydride / acrylic acid copolymer is added and stirred for 1 to 2 minutes (S3100); preferably further included.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter will be described in detail with reference to the accompanying drawings, a method for manufacturing soundproofing and thermal insulation materials for civil engineering and construction according to the present invention.

1 is a flowchart of a method for manufacturing soundproofing and insulating materials for civil engineering and construction according to the present invention. As shown in Figure 1, the soundproofing and insulating material manufacturing method according to the present invention, the soundproofing and insulating material 1000 of the EPS aggregate (1300) and polypropylene fiber (1200) is mixed in the mortar (1100). It is a method of manufacturing.

The material 1000 may be manufactured in the form of a panel or the like, for example, as a single panel, and may be used simultaneously as a sound insulation and a heat insulating material in a ceiling or a wall, and may be used in a road divider or a soundproof wall of a road.

First, prepare cement and EPS aggregate (1300). And it is put into the stirrer 100 for the stirring process. At this time, the input ratio is about 60.70% by weight to about 62.0% by weight of cement relative to the material 1000 to be manufactured, and the EPS aggregate 1300 is about 11.0% by weight to about 12.0% by weight. Agitation of the cement and the EPS aggregate (1300) is performed for about 1 minute to 2 minutes. (S1000)

As the cement is mixed with water and manufactured into a mortar 1100, the cement and the aggregate of the EPS aggregate 1300 in forming the civil engineering and building material 1000 of a predetermined shape together with the EPS aggregate 1300 are formed. to provide. Therefore, the input ratio of cement is relatively higher than the EPS aggregate 1300, and the compressive strength and sound absorption rate when the material 1000 is completed is considered.

After the stirring of the cement and the EPS aggregate 1300 is finished, the polypropylene fiber 1200 is added to the stirrer 100 and stirred for about 1 to 2 minutes. At this time, the polypropylene fiber 1200 is added in a ratio of about 0.2% by weight to 0.3% by weight, which is a weight ratio in consideration of sound absorption and compressive strength of the finished material 1000. (S2000)

Already, the cement and the EPS aggregate 1300 occupy a greater proportion than the entire material 1000, so that the polypropylene fiber 1200 fills the portion where the EPS aggregate 1300 is not located in the manufactured material 1000. do.

After the agitation of the polypropylene fiber 1200, about 25.70% to 27.0% by weight of water is added to the stirrer 100. The injected water is mixed with cement through stirring for about 1 to 2 minutes to prepare a mortar (1100). (S3000)

Then, admixture is added and stirred for about 1 to 2 minutes. In this case, the admixture used is a high performance water reducing agent for high strength of the commercialized material (1000), using naphthalene and maleic anhydride / acrylic acid copolymers as main components, and minimizing slump loss during the manufacturing process. At the same time, it can function to secure early strength for early demolding (S3100).

Thereafter, the mortar 1100 is injected into the mold 200 before being completely solidified, and is compacted through a vibration compression process, thereby being firmly molded according to the shape of the mold 200. (S4000)

Then, if the material is solidified through the drying process, the material 1000 is completed, and after finishing the process of removing the foreign matter protruding from the surface after the demolding process, all the material manufacturing methods are finished.

2 is a process configuration diagram of a method for manufacturing soundproofing and insulating materials for civil engineering and construction according to the present invention. As shown in FIG. 2, the stirrer 100 is equipped with a motor 100a and a screw 100b.

Cement and EPS aggregate 1300 is first introduced into the stirrer 100. At this time, the weight ratio of the cement is about 60.70% by weight to about 62.0% by weight, and the weight ratio of the EPS aggregate 1300 is about 11.0% by weight to about 12.0% by weight. About 10.50kg to about 12kg, and about 2kg to about 2.5kg to the EPS aggregate (1300). Then, the motor 100a is operated to rotate the screw 100b and stirred for about 1 to 2 minutes.

When the stirring process of the cement and the EPS aggregate 1300 is finished, the polypropylene fiber 1200 is added to the stirrer 100. The input ratio is about 0.2 wt% to 0.3 wt% and about 0.04 kg to 0.05 kg is added based on the weight ratio. Then, the mixture is stirred for about 1 to 2 minutes.

Thereafter, about 25.70 wt% to about 27.0 wt% of water is added to the stirrer 100. More preferably, about 4.6 kg to about 5 kg is added based on the weight ratio, and about 1 to 2 minutes are stirred. Add a high-performance water reducing agent and add agitation for about 1 to 2 minutes and finish all the stirring process.

Through the stirring process, the cement is stirred together with water to form mortar 1100, and the EPS aggregate 1300 and the polypropylene fiber 1200 are mixed in the mortar 1100.

The mortar 1100 in which the EPS aggregate 1300 and the polypropylene fiber 1200 are mixed is dropped by the weight through the transport pipe 110 in the stirrer 100 to be contained in the mold 200. A plurality of molds 200 are mounted on the belt conveyor 400. Thus, as described above, the mold 200 containing the mortar 1100 is transferred to the table vibrator 300 by the belt conveyor 400.

The table vibrator 300 is on the right side of the belt conveyor 400. The mold 200 transferred to the belt conveyor 400 is mounted on the table 310 of the table vibrator 300. Then, the mortar 1100 in the mold 200 is compacted by applying the vibration by operating the power switch 300a of the table vibrator 300. The intensity of vibration may vary depending on the amount of mortar 1100 in the mold 200, by adjusting the intensity control switch 300b on the right side of the power switch 300a. At this time, by pressing a mortar (1100) in which a separate compressor (not shown) is vibrated, vibration and compression are simultaneously performed.

Therefore, the mortar 1100 is molded while being compacted by vibration compression together with the mixed EPS aggregate 1300 and the polypropylene fiber 1200. After the process of compaction, the solidification and demolding through the drying process, the sound insulation and insulation material 1000 is completed.

The shape of the material 1000 may vary depending on the shape of the mold 200, and of course, the material 1000 may be manufactured in the shape of all materials 1000 used for civil engineering and construction.

Moldability is provided by the mortar 1100 made of cement and water, and the mixed EPS aggregate 1300 and the polypropylene fiber 1200 are bonded by the mortar 1100. The mortar 1100 occupies most of the weight ratio, and the EPS aggregate 1300 is embedded in the mortar 1100, and the polypropylene fiber 1200 is filled in the portion where the EPS aggregate 1300 is not located.

Here, the EPS aggregate 1300 was used to have an outer diameter of about 5mm to 10mm, and the polypropylene fiber 1200 was used to cut short about 3mm to 4mm. The EPS aggregate 1300 and the polypropylene fiber 1200 are mixed and the mortar 1100 is aggregated to form an overall panel form.
