Abstract
The present invention relates to a polyvinyl chloride resin; And refined fly ash, and a lightweight PVC flooring using the same.
Description
The present invention relates to a lightweight PVC flooring composition and a lightweight PVC flooring using the same.
Floor materials based on petroleum resins such as polyvinyl chloride (PVC) resin are mainly used as flooring materials used in buildings such as houses, mansions, apartments, offices or shops.
Generally, PVC flooring is prepared by processing a PVC flooring composition containing a filler, a plasticizer, a stabilizer, a pigment, an additive, a foaming agent and the like in a polyvinyl chloride resin.
Here, the term "filler" refers to a finely divided powder consisting of a liquid, a semi-solid and a solid in order to change the physical properties of the original composition and to reduce the cost. In the present plastic processing field, the filler is called calcite (calcium carbonate, CaCO 3 ) Punched stone is widely used as a filler.
As a filler, the content of balsam is the most important factor for cost reduction of PVC flooring. When the content of the pellets is 40 wt% or less, the product is a rather expensive product group that can be rolled into a roll classified as a sheet product group. When the content of pellets is 70 wt% or more, X 400 mm), which is classified as a tile product group. However, as both products have the same physical properties, the higher the content of tannin, the more price competitiveness can be secured.
However, due to the leveling of technology and quality in the PVC flooring sector, the increase in the amount of carbon as a conventional filler has limited the ability to secure price competitiveness.
The present invention relates to a polyvinyl chloride resin; And a lightweight PVC flooring composition comprising a filler consisting of refined fly ash.
However, the technical problem to be solved by the present invention is not limited to the above-mentioned problems, and other matters not mentioned can be clearly understood by those skilled in the art from the following description.
The present invention relates to a polyvinyl chloride resin; And a filler consisting of refined fly ash.
The filler may be further punched.
The filler may include 500 parts by weight to 800 parts by weight based on 100 parts by weight of the polyvinyl chloride resin.
The weight ratio of the refined fly ash to the billet may be from 2: 1 to 1: 2.
The particle size of the refined fly ash may be 10 탆 to 100 탆.
The specific gravity of the refined fly ash may be 1.6 to 2.0.
The refined fly ash may be a hollow spherical structure.
The surface of the refined fly ash may be coated with at least one selected from the group consisting of polyethylene glycol, triacetin, propylene glycol, acetyl triethyl citrate, triethyl citrate, and glycerin.
A plasticizer, a processing aid, rosin, a release agent, and an antioxidant.
In one embodiment of the present invention, there is provided a lightweight PVC flooring fabricated from the lightweight PVC flooring composition.
The density of the lightweight PVC flooring may be 1.5 g / cm3 to 2.0 g / cm3.
The lightweight PVC flooring according to the present invention comprises a polyvinyl chloride resin; And a filler consisting of refined fly ash. The resulting product is excellent in tensile strength and tearing strength, and can realize weight reduction of flooring material, while ensuring price competitiveness.
The inventors of the present invention confirmed that the use of refined fly ash as a filler can reduce the density of the lightweight PVC flooring while studying lightweight PVC flooring, and completed the present invention.
The present invention relates to a polyvinyl chloride resin; And a filler consisting of refined fly ash.
The polyvinyl chloride resin is a polymer obtained by polymerization of vinyl chloride. The polymer has a specific gravity of 1.45 and softens at 65 to 85 캜, and plasticity occurs at 120 to 150 캜, and dissolves at 170 캜 or higher. It has excellent acid resistance and alkali resistance and is non-toxic and flame retardant. Also, it has good electrical insulation and is insoluble in alcohols, organic acids and aliphatic hydrocarbons. It swells in aromatic hydrocarbons such as benzene and toluene, and dissolves well in ketones such as cyclohexanone, methyl isobutyl ketone, nitrobenzene and the like. Decomposition occurs when hydrochloric acid is dropped during heating, but decomposition becomes violent when the temperature exceeds 190 ° C. The polyvinyl chloride resin includes a hard polyvinyl chloride resin and a soft polyvinyl chloride resin.
As a filler used in conventional PVC flooring compositions, it is generally used as a filler (calcium carbonate, CaCO 3 ). However, when 100% of the filler is used as a filler, it is difficult to realize a light weight of a bottom material. there was.
Fillers generally refer to liquid powders, semi-solid and solid-state finely divided powders for the purpose of changing physical properties and reducing costs of raw materials. Thus, the particle structure of the filler can be a sophisticated geometric shape, such as spherical, polyhedral and staple fibers, from irregular masses.
In coal-fired power plants, coal is pulverized by a differentiator and injected into the furnace at high speed with hot air. Most of the minerals contained in coal are instantaneously burned in the floating state at 1500 ± 200 ° C above the melting point. I call it. The coal ash contains 30 to 50% of ash for domestic coal (anthracite coal) and 10 to 15% for bituminous coal. The structure of the furnace (change in coal combustion temperature), type of coal (content of CaO Changes in physical and chemical properties depending on the degree of crushing, the period of stay, and the shape of the dust collector. At this time, the pulverized coal in a fine powder state is burned and discharged together with the flue gas in the boiler. The bottom ash, the cinder ash and the bottom ash are classified according to the gathering place.
In other words, fly ash refers to particles that, when coal is burned, fly with the exhaust gas into the air without falling to the floor. Fly ash has a low proportion of fly ash, because many of the fly ash remaining in the combustion process becomes empty space filled with air. However, since fly ash may contain heavy metals, a purification process is particularly required, and it is effective to select the particle size in the process. In order to use the fly ash as a filler for the PVC flooring according to the present invention, it is preferable to select a tablet fly ash having a uniform particle size.
The filler may be further punched.
The above-mentioned coal is used as a general filler in the field of plastics processing. It is a finely powdered powder made by pulverizing limestone. It is weakly alkaline of white color stable at room temperature. It is usually made of calcium carbonate, heavy calcium carbonate And light calcium carbonate. The particle size of the pellet may be 10 탆 to 100 탆, and may be a cubic structure of a crystal phase.
The filler may include 500 parts by weight to 800 parts by weight based on 100 parts by weight of the polyvinyl chloride resin. When the content of the filler is less than the above range, there is a problem in that the function as a filler is insufficient. When the content of the filler exceeds the above range, the workability of the lightweight PVC flooring composition is lowered and mechanical properties such as tensile strength and bending strength There is a problem that the physical properties are lowered.
The particle size of the refined fly ash has a uniform particle diameter, and it is preferably 10 탆 to 100 탆, more preferably 10 탆 to 50 탆, but is not limited thereto. If the particle size of the refined fly ash is less than the above range, there is a problem of accurate metering and measurement due to the non-acidity of the powder particles. When the particle size of the refined fly ash exceeds the above range, there is a problem that the light weight is poor.
The specific gravity of the refined fly ash may be 1.6 to 2.0.
The refined fly ash may be a hollow spherical structure corresponding to a spherical structure having a hole in the center of the crystal phase.
The surface of the refined fly ash may be coated with at least one selected from the group consisting of polyethylene glycol, triacetin, propylene glycol, acetyl triethyl citrate, triethyl citrate, and glycerin. Since the surface of the refined fly ash is hydrophobic, there is a problem in that the plasticizer oil absorption amount is high. As a result, the surface of the refined fly ash is treated with polyethylene glycol, triacetin, propylene glycol, acetyltriethyl citrate, triethyl citrate and glycerin By coating at least one selected from the group consisting of the above-mentioned components, there is an advantage that the flow rate of the plasticizer can be greatly reduced.
The lightweight PVC flooring composition may further include at least one selected from the group consisting of a plasticizer, a processing aid, rosin, a release agent, and an antioxidant.
The plasticizer may be selected from the group consisting of phthalate compounds, allyl phosphate esters, dialkyl ether diesters, tricarboxylic acid esters, epoxidized oils, epoxidized esters, polyalkylene oxides, polyesters, polyglycol diesters, allyl ether diesters, aliphatic diesters , An alkyl ether monoester, a citrate ester, a dicarboxylic acid ester, a vegetable oil, and a glycerin ester, and the plasticizer is added in an amount of 10 to 50 parts by weight per 100 parts by weight of the polyvinyl chloride resin .
The processing aid may be an acrylic resin, a urethane resin or a thermoplastic polyolefin (TPO), and the above-mentioned components may be modified with a polar group such as acid anhydride (maleic anhydride) and / or epoxy, And it is more preferable that the polar group is grafted, but it is not limited thereto. The processing aid may include 1 part by weight to 10 parts by weight with respect to 100 parts by weight of the polyvinyl chloride resin.
The rosin is a natural resin obtained by distilling rosin, and contains abietic acid as a main component and resin acid such as neoabietic acid, lipomic acid, hydroabietic acid, pimaric acid, and dextrin acid, May include 1 part by weight to 10 parts by weight based on 100 parts by weight of the polyvinyl chloride resin.
The releasing agent is for facilitating separation after press or roll pressing. The releasing agent may include 0.1 to 5 parts by weight based on 100 parts by weight of the polyvinyl chloride resin.
The antioxidant is an additive for preventing auto-oxidation due to the action of oxygen. The antioxidant may include 0.1 to 5 parts by weight based on 100 parts by weight of the polyvinyl chloride resin.
In one embodiment of the present invention, there is provided a lightweight PVC flooring fabricated from the lightweight PVC flooring composition.
The lightweight PVC flooring may consist of one layer or may consist of one or more multi-layers.
Wherein at least one of the base layer, the print layer and the transparent layer is formed of a material selected from the group consisting of PVC flooring material, The composition may be processed.
