Description

Eco-friendly and permeable block and the method to manufacture

The present invention relates to an environment-friendly water permeable block and a method for manufacturing the same, in particular, by using a flexible floor on the floor of the sidewalk, bicycle paths, walkways, parks, playgrounds, and the like to alleviate the impact during exercise, giving a variety of colors The present invention relates to an environment-friendly water permeable block and a method for manufacturing the same, which are constructed to increase the visual effect and create a pleasant environment.

In general, the elastic bottom structure, as shown in Figure 1, the lower layer 105 is located on the top of the cut 1, the base layer 103 is located on the upper portion of the lower layer 105, the base layer 103 At the top of the surface layer 101 is located. At this time, the surface layer 101, such as concrete, asphalt, sidewalk blocks, etc., can be permeable to the surface, but the permeability of the base layer 103 is impossible. The construction is to give a gradient to drain.

In order to solve this problem, Patent No. 0449186 filed and filed by the present applicant, as shown in FIG. 2, fine aggregates 11 made of fine residue or waste building material chips include at least one of filamentous silicate or calcium carbonate. Formed by bonding to each other by the included binder, but the lower layer portion 10 consisting of 70-90 parts by weight of the fine aggregate 11 and 10-20 parts by weight of the binder having a particle diameter of 5-50mm; The urethane chip 21 is fixed to the upper portion of the lower layer 10, and the urethane chips 21 are bonded to each other by a binder containing at least one of filamentous silicic acid and calcium carbonate, but the urethane chip having a particle diameter of 1-5 mm 70-90 It is a bottom block using the fine aggregate and urethane, characterized in that it comprises a; and the surface layer portion 20 consisting of 10 to 20 parts by weight of the binder. However, the present invention does not occur the phenomenon of water pooling or splashing, but because the rain is not applied to the silicic acid when the binder is applied to the silicic acid when passing through the lower layer 10 consisting of the binder and the silicic acid, the acid rain immediately As it enters the soil, it does not provide a good effect on the microorganisms growing in the soil by rainwater.

In addition, calcium carbonate, a component used as a neutralizing agent, has a strong alkalinity and its powder has electrical properties, thereby inhibiting the growth and activity of microorganisms in the soil, thereby inhibiting the growth of microorganisms, thereby reducing the growth of trees. It will have a bad effect.

This is because trees generally do not have the nutrients in the soil directly as their nutrients, but the excrement resulting from the activity of microorganisms affects plant growth.

Therefore, the present invention is to provide an environment suitable for the growth of microorganisms, furthermore, to provide an active space of the microorganisms to increase the soil intelligence and the growth and growth of plants.

In addition, rainwater penetrates through charcoal or soil in the process of becoming a groundwater and can be purified and purified to secure high quality groundwater and change the surface environment.

For example, we are well aware that the problem in urban groundwater, a concrete culture, is not bacteria, but phosphoric acid, nitric acid, other heavy metals or other harmful substances in the groundwater.

The present invention may provide a favorable condition for the growth of microorganisms by purifying a large amount of contents, although it may not play a role in removing all such substances from rainwater.

The present invention helps to neutralize the soil and the growth and growth of microorganisms by forming an environmental layer mixed with handmade slag and charcoal on the lower layer in order to solve the above problems, and also to enable the purification of rainwater to increase the growth of microorganisms, The purpose of this is to provide an active space to increase the soil strength, provide an environment suitable for the growth of plants, and to form an adhesive layer to increase the adhesion strength between the surface layer and the permeable layer, thereby eliminating the separation of the surface layer even after a long period of time.

In order to achieve the above object, the present invention is a floor block for paving the road surface is arranged in a plurality of consecutively on the cut ground, the perforated frame a plurality of holes; A lower layer part injected into the bottom surface of the perforated frame and formed by mixing recycled aggregate or residue; An environmental layer formed by mixing charcoal and handmade slag on an upper portion of the lower layer; A water permeable layer formed by mixing aggregate with a primer and a binder on top of the environmental layer; An adhesive layer formed on the permeable layer by mixing an elastic chip and a binder; The upper portion of the adhesive layer is characterized in that it comprises an elastic layer formed by mixing the elastic chip and the binder in a proportion of the binder amount is less than 5% by weight compared to the adhesive layer.

In addition, the lower layer is characterized in that it can be omitted.

In addition, the permeable layer is mixed by using a primer having a low viscosity as a primary in mixing the primer and the binder with other materials, and using a binder having a high viscosity as a secondary, and the elastic layer is formed at the same time as forming the adhesive layer Characterized in that.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 3 to 6.

In addition, Figure 7 is a perspective view of the perforated frame to serve as the mold of the eco-friendly water permeable block according to the present invention.

<Example 1>

Referring to Example 1 in detail with reference to Figures 3 and 4, by using a mixed aggregate first in the perforated frame 71 shown in Figure 7, which serves as a mold in manufacturing the environmentally friendly pitcher block 50 After implanting to a thickness of about ~ 30 cm and flattened to form a lower layer portion (51). At this time, the lower layer portion 51 may be omitted depending on the embodiment.

In the upper part of the lower layer 51, an iron is produced in an ironworks and 70 to 90 vol% of slag of particles 1-3 mm generated as a by-product and 10 to 30 vol% of char processed into particles of 3 to 10 mm are mixed. Forms layer 53.

The upper part of the environmental layer 53 is composed of aggregates and primers and binders having a particle diameter of 5-25 mm, and the aggregates use residues or waste building materials chips, and the waste building materials chips are mainly recycled aggregates generated by pulverizing waste concrete. To form a permeable layer 55 using the.

The adhesive layer 57 is formed on the permeable layer 55 by using a binder composed of an elastic chip and a binder and having a weight ratio of 5% higher than the amount of the binder of the elastic layer 59 mixed with the elastic chip.

And the upper part of the adhesive layer 57 is composed of 70-78 wt% of urethane chips and 30-22 wt% of a binder with a particle diameter of 1-5mm, the urethane chip is formed of a urethane resin, EPDM (synthetic rubber), waste tire, etc. It is also possible to form a rubber chip by mixing with a urethane resin, and the binder forms an elastic layer 59 using a urethane binder.

The materials constituting each of the above layers are used after mixing using a mixing tank. In addition, the perforated frame 71 that serves as a mold is used for the purpose of maintaining the appearance until the curing of each layer to be laminated to some extent as described above, may be constructed separately from the pitcher block after the curing procedure is completed. However, when the time for hardening is insufficient, it is also possible to construct together without separating the perforation frame 71.

Hereinafter, the embodiments will be described in detail with reference to Tables 1, 2, and 3.

Table 1 shows the permeable layer 55 by mixing 94 to 96 vol% by weight of recycled aggregate having a particle size of 5-40 mm, 2 to 3 vol% by weight of primer, and 2 to 3 vol% by weight of binder. The results are shown.

TABLE 1

Recycled aggregates or fines primer bookbinder Porosity Particle Size of Recycled Aggregate (mm) g g g % 5-10 10-20 20-30 30-40 20 30 20 25 95 2 3 17.9 20 25 25 25 95 2.2 2.8 18.3 11 25 25 35 96 2 2 19.2

As shown in Table 1, the residue is 5-10mm, 10-20mm, 20-30mm, 30-40mm, the porosity is different according to the mixing ratio of, and the binding force is different depending on the amount of the urethane binder and primer mixed Resilience also changes.

Since the permeability of the surface elastic chip is 9.78 × 10 ^-2 , the permeable layer 55 can permeate all the amount of rainwater that is permeated from the surface layer through the pores of the elastic chip, even though fine aggregates fill the gaps in the aggregate to reduce the voids. For the relatively high content of fine aggregate does not affect the pitcher.

In other words, when using fine ash or recycled aggregates, fine aggregates of 5-10㎜ can fill gaps to increase bonding strength and increase resilience.

However, smaller particles below them are more dusty, have poor adhesion, increase the amount of urethane binder, significantly lower the porosity and affect the permeability. Therefore, the particle size of 5-40㎜ is most suitable, so the particle size should be maintained.

In addition, the surface dryness of the aggregate is very important because the aggregate bond strength is increased only by eliminating the surface moisture of the aggregate to help the absorption of the primer and eliminating the foaming phenomenon of the binder due to the moisture. Therefore, the dried aggregate should be used.

The binder that binds the fine aggregate is fat-soluble and can be used SBR (Styrene Butadiene Rubber) as a urethane-based and water-soluble, and a binder of high hardness is not suitable, but epoxy and acrylic can be used in some cases.

In addition, the use of primers and binders as a method for increasing binding strength and restoring force facilitates the infiltration of primers in aggregate by using primers with low viscosity when mixing, and binders having high viscosity as a secondary material for aggregates infiltrated with primers. When mixed with, the bonding force is increased, and the restoring force is also increased.

In this case, it is preferable to use the same kind of binder as the adhesive layer 57 which is constructed at the upper end.

In order to increase the bonding strength of the adhesive layer 57 and the permeable layer 55, the bonding strength of the elastic layer 59 and the permeable layer 55 is to be bonded by the bonding ratio of the adhesive layer 57 shown in Table 2 rather than the binder blending ratio of the elastic layer 59. Is high.

[Table 2] Binder Content of Adhesive Layer

Formulation example Elastic Chip (g) Binder (g) Particle size of elastic chip (mm) One 65 35 2 2 70 30 3 3 73 27 4

Table 2 shows the compounding ratio of mixing the elastic chip 65-73g binder 27-35g of the adhesive layer 57 and forming the adhesive layer 57. The permeation block may be formed by forming the adhesive layer 57 at the same mixing ratio as in the mixing example of Table 2 according to the dry state or the particle state of the chip.

For reference, the mixing ratio of the elastic layer 59 is preferably maintained at 77.5 wt% of the elastic chip and 22.5 wt% of the binder.

The amount of the binder can be adjusted as shown in Table 2 according to the moisture content and hardness of the elastic chip.

As shown in Table 2, the mixing ratio of the binder and the elastic chip is different depending on the particle size of the elastic chip, and if the particle size of the elastic chip is less than 1 mm, the permeability decreases, so the size of the chip is 2-4 mm.

In addition, the size of the particle affects the flatness of the surface. In view of this, a size of 2-4 mm is appropriate.

Thus formed adhesive layer 57 fills the gap between the aggregate and the aggregate on the surface of the permeable layer 55 serves to increase the adhesive force of the permeable layer 55 and the elastic layer 59.

Table 3 below shows the water permeability coefficient of the adhesive layer 57 of Table 2, but there is a slight difference depending on the amount of the binder, but when the viscosity of the binder is low, the amount of the binder does not significantly affect the permeability. The formula for calculating the above permeability coefficient is as follows.

      K: Permeability Factor (cm / sec)

      L: Thickness of package surface layer (cm)

a: cross section of the container (cm ² )

A: throwing area (cm ² )

      h1: Measurement start water level (cm)

      h2: Measurement end level (cm)

      t1-t2: pitching time

    [Table 3] Permeability coefficient according to the amount of binder binder

Adhesive layer thickness (mm) Elastic Chip (g) Binder (g) Permeability 5 65 35 9.21 × 10 ^-One 5 70 30 9.12 × 10 ^-One 5 73 27 8.96 × 10 ^-One

In forming the last elastic layer 59 on the adhesive layer 57 mixed in the mixing ratio of Table 3, the elastic chip for the elastic layer 59 is mixed using the same binder as the adhesive layer 57.

At this time, the adhesive layer 57 is formed and at the same time, the elastic layer 59 is formed to increase the bonding force with the adhesive layer 57. In this way, the same kind of binders can be cured at the same time at the same time to maximize the bonding force.

Example 2

5, the present invention can be used in the following embodiments. This method eliminates elastic finishes and finishes the surface of the surface with a uniform residue, making it easier to permeate and beautifully surface to reduce manufacturing costs and smooth inflow of rainwater such as eco-friendly permeability elastic finish. It's a way.

This is because rainwater flows easily and quickly than when passing through the elastic chip to increase the permeability and it is also advantageous to use this method because it is advantageous to secure the permeable layer 55 at a lower cost than the elastic chip.

The lower layer portion 51 is formed flat to a thickness of about 10 to 30 cm using a mixed aggregate in the perforated frame.

An environmental layer 53 is formed on the lower layer 51 to facilitate the growth and growth of microorganisms.

The environmental layer 53 is a mixture of 10 ~ 30 vol% of charcoal processed with 3 ~ 10mm size wood vinegar and iron 1 ~ 3mm slag, 70 ~ 90 vol% of particles produced as a by-product in ironworks It is formed by laying behind.

 A water permeable layer 55 is formed on the environmental layer 53 to facilitate the excellent inflow of the ground. The water permeable layer 55 is composed of aggregates having a particle diameter of 5-25 mm, and the aggregates are made of fine residue or waste building material chips. The waste building materials chip is mainly used recycled aggregates generated by crushing waste concrete.

A gravel layer 61 is formed on the permeable layer 55 by mixing 90 to 92 vol% of residues with 10 to 8 vol% of a binder. At this time, the material for forming the gravel layer 61 is maintained by using a gravel having a particle size of 5-10mm appropriate pores.

Conventional pitcher cones are not permeable over time because the pores are filled by dirt, which is because the concrete is hardened and there is no elasticity, so the blocked pores are not perforated, but the permeable layer 55 may have dirt trapped in the pores. By having a binder with elasticity, the voids can be maintained at all times, so that the pitcher can be continuously made regardless of the passage of time.

<Example 3>

In this embodiment, the finish and the permeable layer of Example 2 and the surface layer is different, the lower layer and the environment layer is the same.

Example 3 forms the permeable layer 55 of Example 1 or 2 and fills the pores of the formed permeable layer 55 with silicic acid to create conditions for grass to grow well. At this time, the silicic acid filling the pores of the permeable layer 55 uses silicic acid having a particle diameter of 1-2 mm, such as sand, and the ph of the silicic acid has a weak alkali of 7.5, which may be a good condition for growing grass. Permeability of the permeable layer 55 may be filled, but the permeability may not be good, but since the permeation rate of silicic acid is 10 ^-2 , even though silicic acid enters the pore, pores are formed due to the permeability of the silicic acid itself, so that the permeability of the permeable layer 55 does not change, so permeability Is made smoothly.

As described above, the eco-friendly water permeable block according to the present invention has a structure that can moisturize at all times by catching moisture rising from below the ground to alleviate the walking impact of the existing elastic flooring material. By providing better elasticity, the effect is not only higher, but also minimized peeling and frictional fall.

It protects water resources, which are the depleted resources of the future, and prevents the backflow of urban sewage due to heavy rains due to heavy rains. By making good conditions for the growth and prosperity of the microorganisms on the surface, it helps the growth of trees and takes part of the natural functional cycle of the natural environment, and plays a role of saving the nature that is destroyed.

In addition, the hydration of the handmade slag prevents the permeation of the ground to occur rapidly, preventing soil loss of the ground and maintaining the surface circular for a long time.

Needless to say, it takes a lot of time and huge funds to restore the damaged nature, but the invisible benefits obtained through the present invention are enormously incalculable.

The present invention uses more recycled aggregates and industrial by-products such as charcoal, handmade slag, and more environmentally friendly elements. Moreover, the fact that rainwater can be smoothly introduced into the soil further doubles the advantage of minimizing the dysfunction caused by the destruction of the environment by using recycled materials as described above.

The problem of cracking and falling, which has been the biggest problem of elastic flooring, has been solved through the adhesive layer, and the bonding strength and resilience of the permeable layer have been improved so that the cracking and falling of the surface do not occur even under the weight load.
