Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Polymer Concrete Composition
The polymer concrete composition according to the invention comprises an aggregate, a binder, a first filler, a second filler and a heat shield.
The aggregate according to the present invention is a crushed stone, steel gravel, silica sand and the like having a particle size of 13mm or less, in some cases using artificial lightweight aggregate, and includes 70 to 75 parts by weight of the total weight of the polymer concrete composition. At this time, the aggregate should be used to dry completely, the higher the strength of the aggregate, the higher the overall strength of the polymer concrete composition.
The binder (Binder) according to the present invention contains 5 to 9 parts by weight of the total weight of the polymer concrete composition. At this time, as the type of binder, an unsaturated polyester (UP) resin, an epoxy resin, a urethane resin, a methyl methacrylate (MMA) resin, a thermosetting resin, and a thermoplastic resin alone Use or mix. Preferably, unsaturated polyester resin and methyl methacrylate resin are used, or unsaturated polyester resin and methyl methacrylate resin are mixed and used. If the binder is less than 5 parts by weight, there is a problem in that the strength decreases significantly. If the binder is more than 9 parts by weight, there is a problem in that the water permeability is lowered due to a pore blocking phenomenon.
The first filler and the second filler according to the present invention are used for increasing the binder, improving workability, improving strength and durability, and the second filler uses a relatively coarse filler as compared to the first filler.
Here, the first filler using at least any one of fine calcium carbonate, stone powder, slag, cement, fly ash and paper ash having a fine powder with a particle diameter of 1 to 30 ㎛, 3 to 15 weight of the total weight of the polymer concrete composition Addition is included. Although the first filler made of such a fine powder is inexpensive and has good physical properties, it is preferable not to exceed 15 parts by weight based on the total weight of the polymer concrete composition because of the problem that the strength is lowered when it is used a lot. If the first filler is less than 3 parts by weight, there is no meaning as a filler. If the first filler is more than 15 parts by weight, the workability is lowered and the amount of the binder is increased to increase the cost.
In the second filler according to the present invention, it is preferable to use fine silica sand having a particle diameter of 20 μm to 40 μm, and more preferably # 8 yarn sand. This second filler comprises from 3 to 15 parts by weight of the total weight of the polymer concrete composition. If the second filler is less than 3 parts by weight, there is no meaning as a filler, and if the second filler is more than 15 parts by weight, the amount of the binder is increased to increase the cost.
Heat shielding material (ceramic hollow particles) according to the present invention is to improve the heat shielding and thermal insulation effect, alumina silicate (Alumino Siliccate) having a hollow spherical shape and a hollow spherical shape having a solar firing effect and heat insulation in the form of bubbles ) Inorganic fine particles such as ceramics and silica alumina ceramics are used alone or in combination. Such heat shield includes 1 to 20 parts by weight of the total weight of the polymer concrete composition. As a preferred heat shield, the present invention uses an insuladd commercialized with an aluminosilicate system. In the present invention, the insulation is used, but any material can be used as long as it has a heat shielding function. If the heat shield is less than 1 part by weight, there is no heat shielding effect. If the heat shield is more than 20 parts by weight, the amount of the binder is increased to increase the unit cost. In particular, the binder is not significantly different in use of 15 parts by weight or more, it is preferable to use 6 parts by weight to 12 parts by weight as appropriate capacity.
The polymer concrete composition according to the present invention may further comprise a small amount of curing agent depending on the use. In this case, the hardener may include 0.5 parts by weight to 5 parts by weight of the total weight of the polymer concrete composition.
In addition, the polymer concrete composition according to the present invention may contain 4 parts by weight to 5 parts by weight of silver ion antibacterial agent based on the total weight of the binder for the antibacterial effect. In this case, the silver ion antimicrobial agent may be contained in a liquid paste or powder state. In this case, it is preferable to use an organic solution-based silver amino acid as the silver ion antimicrobial agent to be used. As such, when the silver ion antimicrobial agent is further included, natural amino acids decompose formaldehyde, which is a skin allergen, and further sterilize pneumococci, Escherichia coli, and Staphylococcus aureus.
One preferred embodiment of the polymer concrete composition comprising the above-described composition is made of a combination as shown in Table 1 below.
