1 is a flow chart schematically showing a method for producing a volcanic stone aesthetic model according to a preferred embodiment of the present invention.

Skin layer formation step (ST100)

This step is to form a skin layer on the outer surface of the existing model.

As used herein, the term "epidermal layer" refers to the exterior surfaces of various types of existing models (e.g., structural materials in the form of blocks or boards, and various stone sculptures in three-dimensional form, as well as landscaping facilities and living containers such as flower pots and flower beds). It means the layer which consists of an additional material to which it attaches.

Regarding the material of the existing model, there is no need to limit in the present invention, various materials are all available. Specific examples may include styrofoam, glass, stone, wood, fiber reinforced plastics (FRP), cement, gypsum, and the like.

The additional material may be a material such as natural fiber (eg cotton), synthetic fiber (eg nylon), glass fiber, or the like, and may be a mesh (eg mesh) or wire (eg string) member. .

First, in the case of a member made of a mesh (eg, mesh) or wire (eg, string) shape, an adhesive or the like may be used to easily attach to an outer surface of an existing model.

Figure 2 is a flow chart showing the detailed steps of the skin layer forming step (ST100) of the volcanic stone aesthetic model manufacturing method according to an embodiment of the present invention.

This embodiment corresponds to the form of attaching the aforementioned mesh or wire-shaped member to the outer surface of the existing model.

As shown, it may first comprise the step of applying the adhesive to the outer surface of the existing model (ST110).

The adhesive used in this step may be changed and changed slightly depending on the material of the additional material to be attached to the outer surface of the existing model, there is no need to limit the kind of the adhesive.

In addition, the adhesive coating method in this step (ST110) may be a method of evenly coating the entire surface using a brush, and a method of evenly spraying the adhesive using a spray gun.

The adhesive is evenly applied to the outer surface of the existing model through this step (ST110), and then wound by attaching a mesh or wire type additive made of any one of natural fiber, synthetic fiber, and glass fiber. To form an epidermal layer (ST120).

Commonly available cotton or a mesh or a string made of a material such as nylon or glass fiber can be used, and by adding such additives, the first foam cement layer laminated later through the outer surface of the existing model is more firmly Can be attached.

Furthermore, a method of planting piles through the entire surface of the existing model to which the adhesive is applied may be used, and in this case, the skin layer forming operation may be easily and quickly performed.

On the other hand, as another embodiment of this step (ST100), although not shown separately, there is no adhesive suitable for the material of the existing model (for example, a material such as PP or PE), or a material such as styrofoam In one case, using a separate physical fastening means can be attached to the outer surface of the existing model in the form of a projection.

Here, a specific example of the "separate physical fastening means" may correspond to a stapler shim, a pin, a screw, and the like. By mounting such a mechanical element in the form of protruding on the outer surface of the existing model, the surface irregularities are imparted so that the first foam cement layer to be described later is firmly laminated.

First foaming cement layer forming step (ST200) .

In this step, the first foam cement composition (hereinafter referred to as "first composition") formed by mixing cement, foaming agent, admixture, reinforcing agent and water is laminated on the outer surface of the existing model having the skin layer and cured to form the first foam cement. Forming a layer.

This step will be described in detail with reference to FIG. 3.

As shown in FIG. 3, first, forming a first composition (ST210).

Here, the first composition, by weight%, refers to a foamed cement composition produced by mixing 56.0-56.5% of cement, 0.04-0.08% of blowing agent, 5.60-5.65% of admixture, 0.18-0.36% of reinforcing agent, and remaining water. Here, the remaining amount of water is preferably contained in an amount of about 58 to 60% relative to the content of cement and admixture. As a specific example, when the content of cement is 800g and the content of admixture is 80g, the preferred content of water may be 510-528g. In addition, in this case, 1 g of the blowing agent, 80 g of the admixture, and 3 to 6 g of the reinforcing agent may be added.

Each detailed configuration will be described.

cement

Cement is preferably contained in 56.0 to 56.5% by weight of the first composition.

If the content of such cement is less than 56% by weight, the flexural failure load may be lower than the target degree, and the strength improvement quality is inevitably deteriorated. On the other hand, when the content of cement exceeds 56.5% by weight, there is a concern that surface cracks may occur after curing due to excessive increase in hardness.

Therefore, in the present invention, the content of cement in the first composition is limited to 56.0 to 56.5 wt%.

blowing agent

The blowing agent is preferably contained at 0.04 to 0.08% by weight in the first composition.

The blowing agent may be made of any one of aluminum (Al) powder, silver (Ag) powder, zinc (Zn) powder, vegetable blowing agent, animal blowing agent or a mixture thereof. As a preferred embodiment, aluminum (Al) powder may be used.

If the content of the aluminum powder is less than 0.05% by weight, it is difficult to obtain a sufficient foaming effect, whereas, if the content of the aluminum powder exceeds 0.07% by weight, it may not be possible to obtain a foaming increase effect compared to the added content. .

Mixed material

The admixture is preferably contained in an amount of 5.60 to 5.65 wt% in the first composition.

In the present invention, any one or a mixture of silica fume, meta kaolin, superplasticizer, and AE water reducing agent can be used in the present invention. As a representative example, silica fume is used in this embodiment.

Silica fume is a kind of silica microparticles | fine-particles made by the dry method, and is produced by burning silicon tetrachloride, chlorosilane, etc. at high temperature in the atmosphere of hydrogen and oxygen. This admixture is a material added to give a special quality or improve the properties of the concrete, in the case of silica fume, when limited to add within the range of 5.60 to 5.65% by weight, the effect of improving the strength of the first foamed concrete is optimal Can be implemented.

Meanwhile, the fluidizing agent may be added to improve the fluidity of the concrete, and in the case of the AE water reducing agent, it may be added for the purpose of improving workability and resistance to freezing. As other admixtures, in order to secure the effect of improving the strength of the first foamed concrete, metakaolin, fly ash, pozzolan, or the like may be added and used.

Reinforcement

The reinforcing agent is preferably contained in 0.18 to 0.36% by weight in the first composition.

Such a reinforcing agent may be made of any one or a mixture of glass fiber, nylon, polyvinyl alcohol (PVA), polypropylene (PP, Polypropylene) cellulose.

In this embodiment, polyvinyl alcohol is added as an example of a representative reinforcing agent.

In this case, when the content of the polyvinyl alcohol is added less than 0.18% by weight, it is difficult to secure the target strength, whereas when the content exceeds 0.36% by weight, the moldability becomes poor due to excessive addition, and the cost This increasing problem is raised.

water

In addition to the cements, blowing agents, admixtures and reinforcing agents mentioned above, a residual amount of water is contained. More specifically, the content of water is preferably contained in about 58 to 60% relative to the content of cement and admixture.

The first composition may be mixed by the content composition ratio as described above, the first composition prepared in this manner is subjected to the step (ST220) laminated to the outer surface of the existing model having the skin layer formed.

Thereafter, the first composition laminated on the outer surface of the existing model is subjected to a step of curing at least 12 hours or more (ST230).

Such curing time is sufficient if at least 12 hours or more, but productivity may worsen due to excessive curing time, it is preferable to limit to 12 to 48 hours.

Then, the first foam cement layer may be firmly formed through the outer surface of the existing model (ST240).

Shredding Preparation Step (ST300) .

This step is a shredding processing step in which a composition prepared by mixing cement, blowing agent, admixture, and water (hereinafter referred to as "shredding composition") is stirred, foamed, dried, and then crushed to be processed into coarse granular crushed materials.

This step will be described in detail with reference to FIG. 4, which shows detailed steps.

First, a step of preparing a composition for crushed materials by mixing cement, foaming agent, admixture, and water in an appropriate composition ratio (ST310).

The composition for the crushed product, in weight%, comprises 56.0 to 56.5% of cement, 0.005 to 0.01% of blowing agent, 5.60 to 5.65% of admixture, and residual water. Description of each of these components is the same as in the first foaming cement layer forming step (ST200), so that duplicate description will be omitted.

However, here, the content of the aluminum powder that can be used as a blowing agent can be confirmed that is formed at a level of approximately 10 to 30% lower than the first composition described above, which is to lower the foaming effect to form a crushed product. Able to know. In addition, it can be seen that the reinforcing agent, that is, the fiber reinforcing agent is missing in the composition material of the crushed material, which can be confirmed that the crushed material does not consider the effect of improving the strength by the fiber reinforcing agent.

Next, a step of stirring, foaming and drying the composition for crushed materials prepared in the previous step (ST310) (ST320). At this time, it is preferable that the drying time is at least 12 hours. If the drying time is less than 12 hours, the curing effect of the crushed product to be crushed later is not secured. On the contrary, if the drying time exceeds 48 hours, it takes excessive time. This results in a decrease in productivity.

In this manner, the composition for the crushed product after the drying process after stirring and foaming is crushed to a predetermined size and provided as a crushed product having a relatively uniform average particle size (ST330).

At this time, the preferable average particle size of the crushed product is preferably 0.2 ~ 9.0mm.

If the average particle size of the crushed material is less than 0.2mm, it may be difficult to implement the porousness to realize the volcanic stone aesthetics. On the contrary, if the average particle size of the crushed material exceeds 9.0 mm, the surface treatment may be difficult due to the excessively large sized crushed material.

Second foaming cement layer forming step (ST400) .

This step is a step of forming a second foam cement layer by laminating the material of the second foam cement layer by mixing with the granulated crushed material prepared in the previous step to the outside of the first foam cement layer.

This step will be described in detail with reference to FIG. 5.

As shown in FIG. 5, a step (ST410) of mixing the crushed product prepared in the previous step with the second composition again.

The second composition herein refers to a foamed cement composition produced by mixing 56.0 to 56.5% of cement, 0.04 to 0.20% of foaming agent, 5.60 to 5.65% of admixture and residual amount of water by weight.

The prepared crushed product having an average particle size of 0.2 to 9.0 mm is mixed with the second composition mixed at the above composition ratio and prepared as a material of the second foam cement layer.

At this time, the content of the blowing agent is 0.04 ~ 0.20%, it can be seen that the upper limit range is increased compared to the blowing agent content of the first composition. That is, if the content of the blowing agent in the first composition is about 1g, the blowing agent content of the second composition may be added in 1 ~ 5g (preferably 3g). This increases the foaming effect so that multiple pore representations can be effectively implemented.

The material of the second foamed cement layer provided is further laminated on the outer surface of the first foamed cement layer described above (ST420). Next, the second foaming cement layer is formed of a second foam cement layer to form an aesthetic appearance of the product through the step of curing for a predetermined time (ST430) (ST440).

The preferred curing time in this step is preferably at least 12 hours, more preferably 12 to 48 hours.

If the curing time of the second foamed cement layer is less than 12 hours, it is difficult to cure hardly to the outer surface of the first foamed cement layer. On the contrary, if the curing time exceeds 48 hours, productivity is inhibited due to excessive time. Results.

Through the previous steps (ST100 to ST400), the existing model of the first and second foam cement layer is sequentially laminated can implement the appearance of volcanic stone, in the conventional case, by applying a general cement or mortar to the model or Compared with the expensive silicon mold, high quality and light weight products can be provided at relatively low cost.

In addition, by forming an additional material on the outer surface of the model, as well as by adding a variety of fiber reinforcing agent having a strength improving effect to the composition of the first foam cement layer, it is possible to improve the structural strength of the product to increase the product durability life. You can expect the effect.

Furthermore, in constructing the second foam cement layer, by using a method of mixing the crushed material of the target average particle size (for example, 0.2 ~ 9.0mm) with the composition again, the structural strength of the product can be strengthened despite being light There is an advantage.

On the other hand, in the present invention, after the second foam cement layer forming step (ST400), by partially scraping the surface in order to give an appearance aesthetic (this operation is possible by using an abrasive such as sandpaper), a plurality of through the surface Pore can be freely implemented. That is, the same or similar three-dimensional aesthetics as volcanic stones can be implemented. This is referred to as surface aesthetication step (ST500).

In addition, after each step, it can give the same color as the actual volcanic stone, which can be enabled by adding a certain amount of inorganic pigment (eg iron oxide) when mixing the above-mentioned composition.

Furthermore, it can be added to the health functionalities that are recently attracting attention according to the use of the product, which can be implemented by adding an illite or photocatalyst component. Through this, far infrared rays or negative ions are radiated to the user of the product to provide a health improvement effect.

In addition, in the case of the present invention, although not shown separately, it is possible to ensure a strong durability against wear or wear by strengthening the surface hardness of the product, for this purpose can further form a hardness-reinforced coating layer on the outer surface of the finished product have. As a material of such a reinforcing coating layer, commonly available epoxy may be used.

As a material of another reinforcing coating layer, 15 to 35 parts by weight of hydroxyethyl hydroxypropyl cellulose, octadecyl 3,5-di-t-butyl-4 based on 100 parts by weight of dipentaerythritol hexaacrylate (DPHA) 10-20 parts by weight of hydroxy hydrocinnamate and 7-15 parts by weight of ethyl 2- [3- (6-nitrobenzol [d] thiazol-2-yl) ureido] acetate may be used. In this case, as a result of measuring the surface hardness of the product using the ASTM D3502 hardness tester, it was confirmed that the surface hardness of about 1.5 to 2 times was strengthened.

As described above, according to the present invention, it is possible to provide a model of the high-volume volcanic stone aesthetic at low cost while providing the same aesthetic appearance as volcanic stone.

In addition, according to the present invention, in order to realize the same appearance aesthetics as the actual volcanic stone, in order to produce a volcanic stone aesthetic model, it is preferable to present the optimum component composition ratio and molding conditions required. Thus, there is an effect that can easily produce a variety of volcanic stone aesthetic sculpture of the desired form.

Further, according to the present invention, by utilizing the existing model provided as it is, by adopting a method of processing the volcanic stone aesthetic to its outer surface, it is possible to shorten the manufacturing process and reduce the manufacturing cost compared to the conventional.

In addition, according to the present invention, in order to colorfully implement the volcanic stone aesthetics on the outer surface of the volcanic stone aesthetic model, it is possible to freely adjust the expression of the pore can be aroused aesthetic attention of the consumer. In addition, since the structural strength of the volcanic stone aesthetic model can be considered, it is highly versatile in various fields and has the advantage of increasing the life of the product.
