Description

Manufacturing method for soil panel with main material of natural soils}

The present invention relates to a soil panel, more specifically, natural earth as the main material, environmentally friendly, no cracking, and a method of manufacturing an environmentally friendly soil panel, flooring and interior and exterior materials that can obtain strength enough to be used for large loads It is about.

Concrete, which is mainly used in modern buildings and civil engineering, has many problems. Therefore, in recent years, natural wood or synthetic wood is used a lot, and in particular, the situation of using earth, an environmentally friendly material, is increasing.

Soil flooring and interior and exterior materials using the soil does not have any chemical smell appearing in the new concrete building, rather, the soil also acts to deodorize and purify the surrounding odor provides a pleasant environment. In addition, the soil has a constant temperature effect that does not respond to changes in the outside air to stabilize the body rhythm by maintaining a constant state of the body. And the soil has excellent humidity control function, so if it's humid, it absorbs it and spits out when it's dry, which prevents the house from getting wet and moldy in the summer, and prevents getting cold even in winter. In addition, all concrete must be disposed of, but the soil is returned to nature and becomes environmentally friendly.

Although the material using the soil having such a good effect has a high value of utilization, it is not practically used because it does not solve the problem of strength or cracking. Or, there are products that have been put to practical use, but the use of too much concrete is mixed to improve the strength of the environment is colorless.

The present invention has been made in view of the necessity as described above, it is an object of the present invention to provide an environmentally friendly soil panel that does not generate cracks by compressing the mixed soil made of natural soil as a main material.

In addition, the present invention has another object to provide an environmentally friendly precast flooring and interior and exterior materials that can be used as a product requiring a large load by using the aluminum extrusion plate as a core material.

As described above, the soil panel or the precast flooring material and the interior and exterior materials according to the present invention can prevent cracking while promoting eco-friendliness using a minimum amount of cement, and in particular, the flooring material and interior and exterior materials use a core material to provide structural flooring materials such as bridge sidewalks. It is possible to obtain strength that can be used sufficiently.

Hereinafter, with reference to the accompanying drawings will be described a method for manufacturing a soil panel using natural soil according to a preferred embodiment of the present invention and flooring and interior and exterior materials using natural soil.

First, the soil panel according to the present invention is prepared by compressing the compounding soil.

The mixed soil is composed of basic soil containing a mixture ratio of masa (a), ocher (b), and silica sand (c) with a ratio of 7: 2: 1, and the base soil has chaff (d), mixed cement (e), and polymer. (f) is further mixed and used.

In the present invention, the mixed soil was tried to have an even distribution from the smallest to the thickest. That is, the mass (a) has a large thickness (a1) and a small thickness (a2) at the same time, the small thickness of the yarn (a2) is smaller than the silica sand (c) and has a larger thickness than ocher (b). And the large thickness yarn a1 has a larger thickness than the silica sand c. Summarized by the formula, ocher (b) <mass (a2) <silica (c) <mass (a1).

Of these, ocher (b) and martha (a2) have a sufficient mixing ratio with a small thickness, whereas the soil with a large thickness generally lacks. Therefore, the chaff (d) was roughly cut and used as a binder of the soil. In other words, the thickness of the rice husk (d) should be about halfway between the silica sand (c) and the mass (a1), the amount of the chaff (d) is sufficient 5 ± 1% of the weight of the basic soil.

Add the mixed cement (e) to 10-30% by weight of the basic soil again to the (basic soil) + (chaff) prepared in this way. Mixed cement (e) is to improve the strength, it is used to mix the general cement with a waterproofing agent 4: 6 by weight. The waterproofing agent induces chemical bonding, which is essential for improving strength. Experiments with mixing only cement found that only the cement amount was increased and the desired strength was not obtained.

The waterproofing agent in the present invention has a component ratio as shown in Table 1 below.

Ingredient Name Content (% by weight) Penetrant 20-24 Shrinkage reducing agent 18-21 Filler 11-15 accelerant 0.1-0.5 Thickener 0.01-0.06 Polymer 0.5-2.5 Water repellent 0.1-2 coloring agent 0.1-2 Strength enhancer 25-36 Abrasion resistant 5-15 Antifoam 0.05-0.7 Dispersant 0.05-0.8

In this case, when the blended cement (e) is blended at 10 wt% or less, sufficient strength does not come out, and when blended at 30 wt% or more, the strength is improved, but the cement is excessively used to match the environmentally friendly material to be pursued in the present invention. I decided to use less than 30%. In other words, even though the cement mixture is used up to 30% for maximum strength, the cement actually used corresponds to 40% of the cement, which is only about 9% of the total mixed soil. For reference, if 10% of mixed cement is used, the actual cement used is about 3.5% of the total mixed soil.

Next, the polymer (f) is mixed 2% or more relative to the basis soil weight. At this time, the polymer (f) is not mixed with the basic soil, chaff and mixed cement, it is sprayed on the upper portion of the mixed soil to penetrate into the mixed soil.
Polymer (f) is a synthetic polymer material produced by polymerization reaction in a dictionary meaning that there are thousands of kinds. Among them, the polymer used in the present invention is an acrylic polymer, and its function in the present invention is
1) As the gap between particles, which is a structural defect of soil, is large, it breaks down when water penetrates.
2) The cement series between the particles of the soil chemically reacts with water to enhance the strength, and the remaining water rapidly evaporates. At this time, cracks occur in the flooring material, and the strength is significantly lower depending on the degree. Therefore, the polymer forms a film that connects the particles between the soil particles, thereby suppressing evaporation time of the water, preventing cracks in the flooring, and also serves to enhance strength.
3) Polymers take a long time to cure when mixed with water and exposed to air. This means that the strength of the flooring material is increased as time passes. For example, the compressive strength of the sample 7 days after manufacture is about 80Kg / cm ² , and the compressive strength increases to 220Kg / cm ² after 28 days. It was confirmed that. This is the same as the concrete strength used in general construction.
As described above, the polymer (f) induces physical bonding of the soil, and serves to solidify the soil in which the polymer has penetrated. In addition, if the polymer is less than 2%, the surface of the polymer is cracked due to the lack of polymer, but more than that may be better, but the experimental results did not find much better than the result of 2% use.

Therefore, if you summarize the mixing ratio of the above mixture soil,

Basic soil = Martha (7): ocher (2): silica sand (1),

The chaff (d), which is the medium size of mass (a1) and silica sand, is 5 ± 1% of the weight of the basic soil,

10 to 30% of the weight of the basic soil with the mixed cement (e) mixed with the general cement waterproofing agent 6: 4,

The polymer (f) is 2% or more by weight of the basic soil.

Next, with reference to the manufacturing process drawing of Figure 1 will be described a method of manufacturing a soil panel according to the present invention with the prepared soil as described above.

1) to prepare the mold 110 to obtain a soil panel of the desired shape,

2) After filling the compounding soil 120 into the mold 110, the flattening operation,

3) When the flattening of the mixed soil is completed, by pressing the mixture on the mixed soil 120 using the pressurizer 130, the first compression,

4) Evenly spraying the polymer 140 on the compressed compounded soil (120).

5) After the polymer 140 is injected, the mixture 110 is filled in the mold 110 and flattened,

6) using the pressurizer 130 to press the compounding soil 120 on the second compression,

7) After evenly spraying the polymer 140 again on the mixed soil 120,

8) Completed by drying in natural state.

In this case, the thickness of the blended soil will vary depending on the intended use, and when manufactured for thick use, the blended soil filling process, the compression process, and the polymer spraying process are repeatedly carried out in two steps as in the above method. The polymer can penetrate deep. That is, since the polymer flows down from the upper surface, the polymer penetrates from the middle to the lower side of the blended soil by the primary polymer process, and the polymer penetrates from the top to the middle of the blended soil by the secondary polymer process.

However, if the soil panel is thin, sufficient penetration is achieved only by the first polymer work, so it is completed by step 8) by skipping steps 5), 6) and 7) after step 4).

At this time, the filling amount of the mixed soil may be determined whether to perform only the first, or up to the second in consideration of the compression ratio of the mixed soil to have a desired thickness.

As described above, the present invention also makes it possible to utilize soil panels made of mixed soil and precast flooring and interior and exterior materials which can be used for large loads by using core materials in the mixed soil.

The core material is an aluminum extrusion plate as shown in FIG. 2, and has a length and width of a desired size, and side plates 101 protruding upward are integrally formed at both ends in the width direction. In addition, at least one reinforcing plate 102 protruding in a “T” shape or “a” shape as shown in FIG. 2 may be further formed in the widthwise center portion of the core 100 along the length of the width. In other words, when the width of the core material 100 is small, it may be used without a reinforcing plate as shown in FIG. 2, and when the width is larger than this, the reinforcing plate having a “T” shape in the center as shown in FIG. It can be used to form (102), if it has a larger width than this can be used to form a "b" shaped reinforcement plate 102 in the center as shown in Figure 3 (b), if larger As shown in (c) of Figure 3 may be used to form a plurality of "a" shaped reinforcement plate 102.

The core material 100 formed in this way is placed on a square mold 110 provided to correspond to the length and width of the core material as shown in FIG. 4 and is manufactured by filling the compounding soil to a predetermined height upward from the bottom surface of the core material 100. . Here, the predetermined height is slightly different depending on the specification of the core material 100, but about 15mm is enough.

Next, a method of manufacturing a flooring material and interior and exterior materials with a core material and a mixed soil will be described with reference to FIG. 5. As shown in Figure 5 the manufacturing method of the flooring and interior and exterior materials according to the present invention,

1) the core material 100 into the mold 110,

2) filling the compounding soil 120 to cover about 15mm to the upper side of the core material 100,

3) flattening the mixed soil 120,

4) Press the mixture on the mixture soil 120 using the pressurizer 130, the first compression,

5) Evenly spraying the polymer 140 on the compressed compounding soil (120).

6) Fill the compounding soil 120 to be covered again 15mm,

7) using the pressurizer 130 to press the compounding soil 120 on the second compression,

8) After evenly spraying the polymer 140 on the mixed soil 120,

9) Completed by drying in natural state.

Here, the thickness of the blended soil is sufficient to about 15mm from the top of the core material, the compression molding over the secondary as in the above process is to allow the polymer to penetrate deep into the blended soil. That is, since the polymer flows down from the upper surface, the polymer penetrates down from the middle portion of the blended soil by the primary polymer operation, and the polymer penetrates from the upper surface to the middle portion by the secondary polymer operation.

However, since the core is contained inside the compounded soil, there is less risk of cracking, so in some cases, the first compression may be sufficient. Therefore, in step 2), the compounded soil is filled with 30mm and then compressed, and steps 6), 7) and 8) may be omitted.

At this time, the filling amount of the mixed soil may be determined whether to perform only the first, or up to the second in consideration of the compression ratio of the mixed soil to have a thickness of about 15mm from the core material.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. . In addition, the present invention relates to a manufacturing method, or soil panels, flooring materials or interior and exterior materials obtained from such a manufacturing method may be included in the present invention.
