Description

Eco-friendly street tree protection plate laminated with acrylic polymer concrete grating and water permeable concrete and the method of manufacturing or construction thereof}

The present invention relates to a methyl methacrylate-based hybrid polymer concrete grating and permeable concrete laminated eco-friendly roadside protection plate and a method for manufacturing the same, and more specifically, permeable concrete containing a sustained release material to gradually supply useful inorganic nutrients to the roadside. The acrylic polymer concrete grating, which has excellent strength and has a through hole to facilitate rainwater permeation, is integrally stacked and is completely harmless and eco-friendly to the human body and street trees, and is a methyl methacrylate system to improve the protection and growth effects of street trees. Hybrid polymer concrete grating and permeable concrete lamination are related to eco-friendly roadside protection plates and their manufacturing or construction methods.

In general, on both sides or one side of the road, parks, residential complexes, etc., a number of street trees or ornamental trees are planted to purify the smoke and polluted air generated on the road at the same time for the comfort of the surrounding environment and aesthetics of the city.

Most of the surrounding area where the trees or ornamental trees are planted is surrounded by concrete, asphalt, or sidewalk blocks, but the boundary between the stem and root, which is the root of the trees, is covered with soil for smooth supply of moisture and smooth growth. Exposed.

When the soil is exposed to the outside as described above, the soil hardens as pedestrians step on it, blocking moisture or air from being supplied to the roots, thereby inhibiting the growth of trees, and the roots and roots due to the loss of soil. Since there is a problem of being exposed to the outside and damaged, most of the roadside protection plates are installed around the roots of the roadside trees to solve the above problems.

Currently, the roadside protection plate forms a roadside protection plate with solid synthetic resin and similar materials or cast iron, but rainwater or the like can be supplied to the root of the roadside tree through the roadside protection plate, or a network structure of various shapes for smooth supply of air In particular, the conventional roadside protection plate as described above is generally formed to be disassembled and assembled because of its heavy weight.

However, the conventional roadside protection plate as described above is mainly formed of cast iron because it is easily damaged when formed of a solid synthetic resin. However, when the roadside protection plate is formed of the cast iron, there is a problem that increases the manufacturing cost. On the other hand, since it has a network, it also easily breaks, and the roadside protection plate made of cast iron has a problem of frequent theft due to its value as scrap metal.

In particular, since the conventional roadside protection plate is formed of a mesh body penetrating the surface and the back surface, when various contaminants such as cigarette butts enter through the mesh body, it has to be cleaned separately, and weed seeds blowing in the wind are soiled through the mesh body. There is also a hassle that it must be removed separately when it enters and grows.

However, the Korean Patent Registration No. 10-1196294 and the Korean Patent Registration No. 10-1835533 are constructed by dividing the roadside protection plate into a surface layer, a center layer, an adhesive layer, and a base layer, respectively, so the structure is complicated and the components of each layer are significantly different. In addition, there was a problem in construction, such as cumbersome in construction, and it takes time to wait for each component layer to cure and harden.

In particular, Korean Patent Registration No. 10-1196294 and Korean Patent Registration No. 10-1835533 were not only harmful to the human body and street trees, but also not environmentally friendly due to the use of an adhesive resin such as polyurethane as an adhesive layer.

In addition, the roadside protection plate of Korean Patent Registration No. 10-1815017 consists of a base layer 100, a oyster shell main layer 200, and an upper layer 300, but the base layer 100 and the upper layer 300 are ethylene vinyl acetate emulsions (Ethylene- Vinyl Acetate Emulsion) 50 to 60 parts by weight, acrylic polymer emulsion (20 to 30 parts by weight), synthetic rubber latex (Synthetic Rubber latex), 5 to 10 parts by weight of polymer mixture and water diluted in a weight ratio of 1 to 4 As one polymer liquid curing agent was cured, there was a problem that it could not be used because it had little water permeability.

In addition, the roadside protection plate of Korean Patent Registration No. 10-2014755 is made of cured and cured concrete only with a cement concrete composition, so there is a problem that the strength is weak and easily broken or cracked.

Hereinafter, embodiments of the present invention and/or drawings will be described in detail so that those skilled in the art to which the present invention pertains may easily practice. However, the present invention may be implemented in various different forms, and is not limited to the embodiments and/or drawings described herein.

First, referring to [FIG. 1] to [FIG. 3], the methyl methacrylate-based hybrid polymer concrete grating and permeable concrete laminated eco-friendly roadside protection plate of the present invention include 30-50 parts by weight of water and ethylene vinyl acetate ( EVA) 50-70 parts by weight, methyl methacrylate monomer (MMA), 2-ethylhexyl acrylate monomer (2-EHAM), methacrylic acid (MAAC) and ammonium persulfate (APS) radical polymerization initiator Including 20-30 parts by weight of the emulsion-polymerized acrylic polymer, 50-70 parts by weight of No. 7 silica, 20-30 parts by weight of ordinary cement, and tert-butyl hydroperoxide (t-BHP) A polymer concrete grating layer 101 formed by curing a methyl methacrylate-based hybrid polymer concrete composition comprising 2 to 5 parts by weight of a curing agent and having a plurality of through holes facilitating permeation of rainwater; The oyster shell and porous feldspar impregnated with an integral part of the polymer concrete grating, 15 to 20 parts by weight of cement, 60 to 70 parts by weight of coarse aggregate, 15 to 20 parts by weight of fine aggregate, and inorganic nutrients of street trees The permeable concrete layer 102 formed by curing the mortar composition formed by containing 5-10 parts by weight of the formed sustained release material is integrally stacked to be harmless to the human body and roadsides, and is environmentally friendly, and improves the protection and growth effect of the roadside Is formed.

In the present invention, the ethylene vinyl acetate (EVA) used in the polymer concrete grating layer 101 is a polymer obtained by copolymerizing ethylene and vinyl acetate monomer, and the density increases while the content of vinyl acetate increases, while the crystallinity decreases. Flexibility increases. In particular, since EVA is excellent in impact resistance (especially at low temperature), stress cracking resistance, and elasticity, it is characterized in that it is used as an impact and elastic reinforcement material for the polymer concrete grating layer of the present invention.

In addition, the methyl methacrylate monomer (MMA) used with the ethylene vinyl acetate (EVA) in the polymer concrete grating layer 101 is an eco-friendly polymer that is completely harmless to the human body and is a colorless transparent liquid with C4 oil as the raw material. The prepared tert-butyl alcohol (TBA) is oxidized in a gaseous state to prepare methacrylic acid, which is produced by esterification with methanol, that is, through a polymerization reaction process of acrylic acid and mitacrylic acid ester. It is a reactive resin made to have a carbon bond and has the formula CH2=C(CH3)CO2CH3.

This, methyl methacrylate monomer (MMA) is a rigid type and flexible, and when radically polymerized at low temperature, the polymer chain structure exhibits a property of increasing the proportion of syndiotactic structures that exhibit continuous regularity, so it is durable. It has excellent physical properties such as heat resistance, chemical resistance, abrasion resistance, and UV safety, and has excellent weather resistance, which is weather- and weather-resistant such as sunlight, so it suppresses corrosion due to external environmental changes (weather and climate change) and penetrates into the package. It improves adhesion strength and toughness by integrating them, has good properties for coloring by pigments, etc., but has a high coefficient of thermal expansion, but is a highly stable resin, so it has excellent transparency, weather resistance, and colorability, and is used in many fields.

However, MMA starts curing when a small amount of a curing agent is added in the amount of 2 to 5% of the amount of resin, and it is a super-hardening resin that is completely cured within 1 hour after the start of curing. This is excellent, so it can be installed and finished in a large area, and when using this MMA as a waterproofing composition, its strength after curing is very good, but it has insufficient crack resistance and bending follow-up properties, as well as different thermal expansion characteristics with the base body. Therefore, there is a problem that cracks are likely to occur when used outdoors rather than indoors.

In the present invention, in order to complement the MMA shortcoming, a polymerization composition obtained by mixing radical polymerization by mixing 2-ethylhexyl acrylate monomer (2-EHAM) and methacrylic acid (MAAC) with methyl methacrylate monomer (MMA) is used. The 2-ethylhexyl acrylate monomer (2-EHAM) and methacrylic acid (MAAC) are mixed and used to supplement the crack resistance of the methyl methacrylate monomer (MMA) with ductility properties after curing.

On the other hand, the most essential feature composition of the present invention is a water permeable concrete formed by curing mortar composition comprising 5-10 parts by weight of a slow release material composed of oyster shells and porous feldspar impregnated with roadside inorganic nutrients in a weight ratio of 1:1. It is about the floor.

Oyster shells, which are industrial wastes, that is, oyster shell shells, are emitted about 230,000 to 300,000 tons annually in Korea. However, the law on the prohibition of marine dumping of land waste came into force in 2014 and was fully implemented in 2016.However, it must be disposed of in the farm where oyster shells are generated.However, it is difficult for farmers to deal with it due to excessive landfilling, oyster shell collection and transportation costs, etc. There is this.

In the case of currently occurring oyster shells, only about 30 to 40% are used as cultivated seedlings and fossilized fertilizers for oyster farming, and the rest are left on the shore, public waters, or illegal landfills. It is causing environmental problems such as complaints caused by leaks and severe odor.

And the main component of oyster shell is calcium carbonate, which is mainly used in the manufacture of products to consume a large amount of calcium carbonate, which can be used as feed for fertilizer and poultry, or can be mainly used in the manufacture of calcium chloride, calcium carbide and lime, but limestone Its use is low due to weakened price competition with industrially treated low-cost lime.

However, the oyster shell has a multi-layer structure and is pulverized and recycled for each particle, and the recycling uses are used for agricultural fertilizers and aggregates of pots.

Therefore, in order to solve the above problems, as the commercialization technology using oyster shells, which are industrial wastes, is required, through the present invention, calcium of industrial wastes, oyster shells, is used not only as an inorganic nutrient for street trees, but also in the layered structure of oyster shells. It can be used as a sustained release agent that impregnates inorganic nutrients and releases them slowly, thereby improving the growth of street trees.

On the other hand, feldspar is a major component of granite and is an aluminum layered silicate mineral containing potassium, sodium, and calcium. It is a crude rock mineral that occupies the largest amount in the earth's crust.It is an aluminum layered silicate mineral that is the main component of granite. ,Na,Ca)(Al,Si)4O8.

Most natural feldspars belong to three single-component families: potassium feldspar (K-feldspar) (KAlSi3O8), sodium feldspar (plain feldspar) (NaAlSi3O8), and calcium feldspar (CaAl2Si2O8). Sodium feldspar forms a solid solution continuously along the Bowen's reaction series, each of which is collectively called alkali feldspar and plagioclase.

Particularly, during the weathering process, fine pores are characteristically developed on the surface of the feldspar. Due to the porous structure of the feldspar, the specific surface area increases, the volume characteristic decreases, and the surface characteristics increase, resulting in electrical/magnetic and optical properties. It is known to be expressed.

In the present invention, not only the potassium and calcium components of the porous feldspar can be used as an inorganic nutrient component for street trees, but also as a sustained release material that is impregnated and slowly released by impregnating the porous feldspar with inorganic nutrient components to improve the growth of street trees.

In addition, olivine is a silicate mineral containing magnesium and iron components and has a chemical formula of (Mg,Fe)2SiO4, and is one of the major crude rock minerals having an orthorhombic crystal form. It is a solid solution located between Goto olivine (Forsterite; Mg2SiO4) and iron olivine (Fayalite Fe2SiO4), both of which contain magnesium and iron, and is also called olivine or clisolite.

.

In addition, olivine releases far infrared rays 3 to 4 times that of ordinary ores and has an extremely high anion (bioion) generation rate, thereby purifying air pollution that is the cause of chemical, electrical, and radioactive substances, and removing harmful substances such as formalin. It has a purifying effect.

In the present invention, the growth of street trees can be improved by using the magnesium and iron components of the olivine as a sustained release material that is impregnated into the oyster shell and porous feldspar and slowly released.

That is, after immersing the oyster shell and the porous feldspar in an emulsion mixed with water by pulverizing the olivine with a powder of 325 mesh or less, pressurized to impregnate the multi-layer structure of the oyster shell and the porosity of the feldspar to dry the rainwater as dry. Thus, the horizontal and inorganic mineral components of calcium contained in the oyster shell, magnesium and iron contained in the olivine, and potassium and calcium contained in the porous feldspar are gradually eluted and permeated.

At this time, the oyster shell and porous feldspar preferably has a particle size in the range of 3 to 8 mm.

Meanwhile, the polymer concrete grating layer may further include reinforcing fibers selected from glass fibers, carbon fibers, and Kevlar fibers, and the permeable concrete layers may include nonwoven fabrics, carbon fibers, glass fibers, aramid fibers, and polyester fibers. It is advantageous in terms of strength that a reinforcing fiber layer reinforced with a reinforcing fiber selected from metal fibers is further formed.
