Description

[0001] The present invention relates to a water-permeable pedestrian porous block using recycled ceramic material,

The present invention relates to a water-permeable packing block using a continuous ceramic pore structure, and more particularly, to a packing block made of a conventional asphalt or concrete packing material which does not become a pitcher, To improve the strength and permeability of spherical ceramic aggregate in the form of round granules formed by soft grinding and friction grinding with a particle size of less than 5mm so as not to collect waste fragments such as waste glass such as glass bottles glass or incombustible waste ceramics. Which is formed by dispersing and mixing an epoxy resin as a thermosetting resin and hardening and shaping it in a block shape so that the resin sticks to the space between the spherical ceramic aggregate and the ceramic aggregate uniformly and without sticking, Non-adhesion between ceramic aggregates Permeable packing using a continuous ceramic pneumatic structure that satisfies water permeability while being morphologically stable with mechanical strength having both tensile strength and flexibility such as durability and lightness, As regards the block,

Since the present invention has high porosity and excellent permeability, surface water can flow naturally into the ground during rainfall without a separate drainage structure on the roadway and the sidewalk, and slip phenomenon does not occur due to the formation of water on the block surface, It is a water permeable structure that does not form a hole on the surface. It prevents hall closing phenomenon such as soil or dirt which damages the city aesthetics without a safety cover. It can realize a visual decoration effect simultaneously with excellent formative beauty. Quality, high value-added recycling block that is economical and reduces the pollutant emissions, and is environmentally friendly and does not generate toxic substances. Therefore, it is possible to effectively replace the conventional packaging materials, Continuous pore structure The pulmonary ceramic relates to a water-permeable paving blocks used.

Recently, due to the concentration of population in the city, the development of residential land has been increasing, and packaging such as India and roads where people or automobiles are passing is proceeding rapidly.

Typically, the roadway is packaged as a road surface with impervious asphalt concrete or cement concrete, and the sidewalk is packed with a sidewalk with a sidewalk block. However, all the conventional packing materials used to pack sidewalk and sidewalks are all made of concrete or asphalt, Or an impermeable material that does not allow air to pass through.

Particularly, the conventional sidewalk block composed of impermeable packing material flows into the outflow port of the road such as a road boundary point having a concrete structure as a drainage facility and does not directly penetrate the road surface in the case of rainfall during summer or rainy weather, In addition, since the groundwater resources are not effectively supplied with natural precipitation, the underground water in the ground where the sidewalk block is installed becomes insufficient and the underground environment is devastated, which causes destruction of the ecosystem. Especially when heavy rains come down The sidewalks were submerged or rainwater flowed into the rivers quickly, causing natural disasters such as river flooding, odor generation, and urban core heat flux.

In addition, the conventional press block made of impermeable packing material can not drain water quickly on the surface, causing a water film phenomenon, and therefore, it is easy to slip, and water on a walkway or a road is splashed on a pedestrian or the like.

Therefore, measures for directly infiltrating the rainwater into the underground have been required. In recent years, the non-watertight press block has been improved and a porthole press block having a drain hole capable of being cured by the permeable concrete and permeated with rainwater has been developed Such a porthole block can penetrate rainwater and the like but it is likely to be clogged due to foreign substances flowing into the hole formed on the surface of the block and exposed to the outside, and the shoes may fall into the hole of the bend and the pedestrian may be injured. Which is easily damaged by an external impact.

Recently, a permeable asphalt concrete has been developed in order to solve the above problems. The water permeable asphalt concrete developed in this way is pumped into the ground by the gap between the aggregate and the aggregate to supply water to the trees, It helps to grow, and as the rainwater falling in the rainy season is pumped into the ground, it has the effect of delaying the inflow of water into urban river by that much, which is a crucial help to prevent flooding of rivers and rivers. In the case of permeable asphalt concrete, when the temperature of the road surface rises in the summer, the permeability is lowered due to the deformation of the road surface or melting of the asphalt, and the permeability of the concrete is lowered when the amount of rain is lowered. Because it drains to sewer or river, The holding is also expensive, and poor workability problems with the working process complicated nature of the asphalt composition

Waste ceramic wastes such as waste wastes and waste ceramic wastes such as waste ceramic wastes are increasing in quantity but they can not be incinerated and can not be decomposed by nature. Therefore, wastes containing waste glass Recycling is encouraged in order to reduce the amount of landfill. However, since there is no recycling scheme available, the recycling rate in Korea is low.

Therefore, although a typical method for utilizing waste ceramic such as waste glass waste for road use as an aggregate of asphalt or cement concrete has been conventionally proposed,

The production cost is high and the construction is complicated, the strength and the impact resistance of the raw material are low, the handling is inconvenient, and the use thereof is limited, and the sufficient permeability and strength are not given to the packaging material, There is a problem in that it does not satisfy all the requirements for comprehensive use required for

Therefore, the Applicant has attempted to develop a water-permeable packaging block using waste ceramics by improving the packaging material of the prior art, which has many problems as described above. As a result, permeability, formability, safety, economical efficiency, The permeable packing block using the waste ceramic of continuous pore structure of the present invention was developed.

As described above, the water permeable press block of the prior art has various problems,

The present invention has been made to solve the above-mentioned problems,

As a recycled aggregate of waste ceramics as a substitute for a pavement block made of a conventional asphalt or concrete pavement which does not become a pitcher, it can be used as a recycled aggregate, in order to prevent flammable waste fragments such as soda lime glass bottled glass, In order to improve the strength and permeability of spherical ceramic aggregate in the form of a round granule formed by soft grinding and friction grinding with a soft roundness of 5 mm or less, an epoxy resin as a thermosetting resin is dispersed and mixed, Between ceramic spherical aggregate and ceramic aggregate evenly dispersed Adhesive layer between spherical ceramic aggregate formed by sticking to point without sticking of resin to the space. Continuous porous layer of pores. Good durability and light weight, molding Tensile strength and flexibility While at the same time to a mechanical strength having morphological stability to meet the water permeability it is aimed to provide a water-permeable paving blocks with a closed ceramic of the continuous pore structure.

As described above, the permeable packing block using the continuous ceramic pneumatic structure according to the present invention is excellent in the permeability and moldability required for the drainage of rainwater, so that it can effectively replace the conventional bottom packing material, It is effective to utilize waste resources effectively in an environmentally friendly way.

Particularly, the present invention has good physical properties such as compressive strength, porosity and permeability, and is thin and light to reduce the load. At the same time, it has a large porosity distribution of various sizes and a large porosity, The surface water can flow naturally into the ground during rainfall without a separate drainage structure in which a gradient is formed in the roadway and the sidewalk, and the slip phenomenon does not occur due to the formation of the surface of the block surface, so that the pedestrian safety It prevents the hole closure of soil or dirt that damages the city aesthetics without the grating safety cover where the grid structure is formed with the permeable structure that suppresses the occurrence of accident and the hole is not formed on the surface.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The present invention relates to a recycled aggregate of waste ceramic material as described above, which is a spherical ceramic in the form of a round granule which is formed by soft grinding and friction grinding of particles of less than 5 mm in size so as not to collect waste incinerator, waste incinerator, Improvement of strength and permeability by mixing complementary epoxy resin and curing agent as thermosetting resin in aggregate By dispersing and mixing binders for use and solidly curing and forming in a block shape of three dimensional network structure, Between the ceramic aggregate of spheres uniformly dispersed and adhered and the spherical ceramic aggregate formed by sticking the resin to the space between the ceramic aggregates, the non-adhesive layer is a continuous porous layer of voids, so that the binding force is good and durability and light weight, It is morphologically stable with mechanical strength with both tensile strength and flexibility Permeable packing block using waste ceramic of continuous pore structure which satisfies water permeability.

In the present invention, the recycled aggregate of the waste ceramic material constituting the pavement block skeleton is composed of complementary materials which are complementary to each other to easily form a solid waste, such as plate glass, automobile glass, one time mercury bottle, milky white bottle, incandescent lamp, · Waste ceramics such as glass containers, mirrors, cosmetics, etc., or waste ceramics or wastes that contain a large amount of kaolin as a viscous fluid having a large specific surface area and a large number of pores formed therein are crushed as a raw material for forming a permeable block First, the shredded waste glass pieces, the waste ceramic pieces, and the worn-off pieces are sharply polished so as to completely remove the corner portions by rotating the second shot of the slices again. Preferably, the spherical shape, that is, By forming spherical ceramic aggregate in the form of round granules which do not clog by removal, The waste ceramic aggregates are bonded to each other only by the contact points of the sphere and the spheres so that rainwater can be permeated through the pores formed by the adhesion of the spherical ceramic aggregate materials. In other words, Thereby forming a porous water permeable block having pores formed therein.

In the present invention, the crushing process for crushing and scrapping waste glass, waste ceramics or waste agglomerates is repeated in two stages. This is because only a single crushing process using only a crusher can be used as a waste glass piece (cullet) Since the corrugation can not be removed and therefore it can not be formed into a spherical shape, it is possible to rotate freely and rotate freely from the inside to make numerous collides with each other. Using a rotary crushing and grinding machine for recycled aggregates, firstly crushed ceramic pieces are crushed, crushed, A secondary crushing and grinding process using a rotary agitation crushing and grinding machine in which aggregates are formed in a spherical shape having good quality granules in which the corners are completely removed by friction grinding and the angle of the particles is smoothly formed.

That is, the rotary agitation crushing and grinding machine employed in the secondary crushing and polishing process is a rotary agitation crushing and grinding machine equipped with a rotary drum type agitator equipped with a plurality of agitating blades, When it is rotated downward, the crushed waste ceramic collides with the stirring wing and friction occurs, and the corners of the crushed ceramic aggregate are worn and polished to be rounded in the form of spherical granules

In the present invention, the particle size of the spherical ceramic aggregate made of waste glass or waste ceramics is adjusted to be not more than 5 mm by adjusting the particle size to suit the application, It is preferable to crush the aggregate in the form of a single particle. The aggregate has a single granularity so that the binder resin surrounds the particles of the spherical ceramic aggregate, 6-way structure that makes thin and thick adhesion between spherical aggregate particles solely by bonding point As the binder resin is adhered to multi-diffusion structure of three-dimensional network by contact adhesion, sufficient pore between particles can be ensured so that the porosity of expanded pore structure of small- And therefore the coefficient of permeability can be formed to be high.

Particularly, in the present invention, the particles of the waste ceramic are formed to have a particle size of 5 mm or less in order to secure the maximum porosity and proper strength. When the particle size is less than 5 mm, the porosity is low but the porosity is high. Because

In addition, in the present invention, as a solid waste which is a ceramic-based waste material but has different properties, a large number of pores are formed as a raw material in a soft overhead in addition to silicon-based waste glass in a relatively heavy and heavy medium- The use of waste ceramics or pulverulent insulators, which are blended with aged stone ore, facilitates molding by utilizing the expansion force of the clay having micro pores having a high specific surface area as a raw material which can be easily joined to each other, And increasing the surface area of the wide and continuous pore distribution of various sizes in which the micropores of the clay are combined with the large and small pores, thereby maximizing the area and the porosity in contact with the rainwater, thereby greatly improving the permeability of the rainwater Surface due to lack of viscosity during adhesive bonding with binder It has hardness and ductility at the same time because it suppresses the generation of racks and is firmly adhered. It also improves the strength to strengthen the structure and forms permeability, formability and cushioning by forming a morphologically stable packing block without cracks It is to be able to satisfy all.

The waste glass of the transparent material or the opaque porcelain and the waste agglomerate are selectively collected according to the kind of each color before the crushing and the foreign materials such as wood pieces attached to the surface are removed by a method such as washing and used And the grinding and polishing process may be performed by a continuously controlled automatic consistency control system in which an unillustrated microprocessor is embedded and a system control of an electronic control device operated in an optimum operation state by a predetermined program is performed. It is preferable to constitute the apparatus as a stepped drive unit from the first stage of the feedstock supply to the final stage of the block molding. The bag filter for removing scattered dust generated in the crusher, the sorter for removing impurities , And a vibrating screen screen for even grain size can be additionally provided All.

In addition, as described above, at least one spherical ceramic aggregate selected from spherical ceramic aggregates having a particle diameter of 5 mm or less in the raw material grinding and polishing process is mixed at an equivalent ratio of 1: 1: 1, 90% by weight with respect to the total weight ratio of the raw materials, and an amine type such as an epoxy resin which is a subject for bonding the ceramic aggregate of the spherical particles and a polyamide resin which bonds the spherical ceramic aggregate quickly as a to- 10 weight% of a thermosetting binder resin mixed at a mixing ratio (weight ratio) of 1: 4 was mixed and solidified by only six-point bonding of a spherical ceramic having a hexagonal structure, followed by curing for 48 hours or longer Spherical) Ceramic aggregate A pavement-type structure with a thickness and a width of a square so that rainwater, etc., It is sex.

In this case, the binder formed of the thermosetting synthetic resin mixes the surface of the aggregate with only a slight degree of wetting, and bonds the spherical ceramic aggregate to only the contact point of the spherical ceramic aggregate, thereby allowing the rainwater and the like to penetrate to the underground through the gap formed between the spherical ceramic aggregates. Thereby forming a block in which the permeable structure according to the present invention is formed.

Particularly, the present invention relates to a continuous porous layer of a non-adhesive layer void between spherical ceramic aggregates, which is excellent in binding force and is stable in morphology with mechanical strength having both tensile strength and flexibility such as durability, Porous ceramic material permeable block with high strength, durability and high permeability coefficient is formed by pore structure.

The above-mentioned packing block form of the present invention is exemplified by a square packing block, but the present invention is not limited to this, and various types of packing blocks can be formed.

In addition, the present invention is characterized in that the pulverized waste ceramic spherical aggregate and spherical aggregate are mixed with a thermosetting binder resin, coated and bonded together, and then cured. When the binder coating is cured, aggregation of resin occurs around the adhesion point due to exothermic action, Since the resin film is thinner than the non-adhesive surface, the strength is high and the porous structure of the spherical ceramic aggregate becomes uniform. Therefore, the bonding force is doubled and the permeability is improved by continuous pores to form a high- .

In the raw material composition of the present invention, the waste ceramic aggregate is 90% by weight based on the total weight of the total raw materials, and is spherical as an adherend with an epoxy resin, which is a subject for bonding the ceramic aggregates of the spherical particles. 10% by weight of a thermosetting binder resin mixed with an epoxy resin and an amine-based curing agent in a mixing ratio (weight ratio) of 1: 4 is dispersed and mixed to form a block.

The epoxy resin functions as a bonding agent for bonding spherical waste ceramic aggregates to each other due to its strong adhesive force, heat resistance and chemical resistance, and the curing agent is an epoxy resin mixed with a spherical waste ceramic aggregate A function of accelerating the curing of the epoxy resin is performed by the dispersion effect which prevents the droplet from being squeezed to one side when it is cured,

The binder resin is preferably used in an amount of 10% based on the total weight of the total raw materials. If the binder resin is excessive, the porosity is lowered to lower the permeability, and if the binder resin is too small,

When the ratio of the epoxy resin to the curing agent (weight ratio) is 1: 4, when the curing agent is smaller than the above ratio, unreacted portions are formed and the epoxy resin as a main component is hardly cured. When the epoxy resin is excessively cured to be

The epoxy resin can not change the curing time due to outside temperature, so it is used for summer and winter. In the present invention, epoxy resin is used for summer when the outdoor temperature is 15 ° C or higher and winter type epoxy resin when it is lower than 15 ° C.

In particular, the present invention relates to pulverized ceramic raw materials which are sand, soda, and lime, which are melted at a high temperature and are relatively hard and heavy in weight, and fired as a raw material, clay, Recycled aggregates such as waste ceramics and waste insulators are used as soft ceramic products because they can be easily cured at room temperature without being subjected to a separate heat treatment with a binder resin.

Particularly, the above-mentioned waste ceramics and clogs having a comparatively large specific surface area and porosity and formed by mixing clay have good moldability to maintain the shape of the block when they are combined with the waste glass by viscous force, The waste glass piece reinforces the hardness of the surface layer of the pavement block to improve the abrasion resistance and stabilizes the block morphologically so as to form a porous ceramic porous block with high strength and permeability. It is possible to maintain the drainage function constantly at all times while supporting the load and preventing the sinking due to the overload.

As a result, in the permeable packing block using the waste ceramic of the continuous pore structure of the present invention,

A paving block is formed in a square shape having a predetermined thickness and width in a permeable structure so that rainwater or the like is permeated through the pores formed by the adhesion of crushed spherical ceramic aggregates to each other. Recycled aggregate materials such as waste glass, waste ceramics, and waste agglomerates, which are different from each other by binder resin, are uniformly dispersed and tightly and tightly bonded, thereby preventing cracks caused by the generation of pores and forming a smooth surface and a cushion Watertightness for passing water through and waterproofing for blocking hot or cold air are appropriately harmonized so as to solve the problems of pavement and formability of conventional concrete or asphalt pavement block.

As a result, the present invention is a non-combustible waste which has not been corroded or naturally extinguished and has been conventionally simply discarded. As a result, waste ceramics such as waste glass, waste ceramics and waste batteries, which cause serious problems to the environment and cause waste of resources, By forming a pourable pavement block with recycled pores with appropriate strength, it is possible to realize a composite synergy effect that maximizes the aesthetic effect of saving economical, environmentally friendly, discolored and discolored waste glass. When the packing block according to the present invention is installed on the road, water flowing from the surface of the road can be passed through to the lower portion of the block without any additional grating. Also, the pedestrian block having a certain area and thickness, Or landscape blocks in the park. This modification can be used to fit your needs.

As described above, in the case of the water-permeable packing block using the continuous ceramic pneumatic structure of the present invention, when water is easily drained such as rainwater or the like, the water is permeated without any additional gradient adjustment, It prevents the depletion of underground water and prevents flooding due to summer rainy season heavy rain. It has a high porosity and maintains a high sliding resistance. It has a rough surface texture and it does not cause slip due to formation of water film. It prevents pedestrian safety accident by preventing pedestrians from slipping, and it can improve the visibility of roads and indices by reducing diffuse reflection and glare at night because there is no water film, As a result of the temperature reduction effect, sland).

As a result, the present invention provides a low-cost, high-quality, high-value packaging block which is economical and economical and environmentally friendly due to resource saving by recycling waste resources, The material can be effectively replaced and the waste resources can be utilized effectively.

Also, even if the respective components of the above-mentioned examples are partially added and controlled and their amounts are controlled, they are not largely different from each other in physical properties
