Description
Description METHOD FOR FABRICATING POLYETHYLENE COMPOSITION HAVING GLASS FIBER Technical Field
[1] The present invention relates to a composition used by mixing with an architectural material or a pipe material, and a method for fabricating a composition and a composition of the same which have a high strength, chemical resistant property and environment friendly property by mixing a glass fiber with a high-density polyethylene. Background Art
[2] Generally, as an architectural material, concrete is generally used, and as a pipe material, a PVC (polyvinyl chloride) is generally used. The concrete is formed in such a manner that cement, sand, grabble, etc. are mixed with water, and a mixture is hardened with forms. The concrete may be damaged by an external impact or vibration. The PVC which is generally used as a pipe material may generate harmful gas during a process for thereby causing a critical environment problem.
[3] In order to overcome the above problems, a certain metallic material such as a steel core, etc. is inserted into the interior and is hardened for thereby enhancing strength. However, in the case that the concrete is broken, the steel is directly exposed to the outside for thereby generating a dangerous state. In addition, the exposed steel may began to rot due to moisture, so that the concrete may be easily broken, and an outer appearance is damaged.
[4] As the pipe material, the PVC may be used. The polyethylene resin is used as an alternate material. However, the polyethylene is environmentally friendly but has weak heat resistance property based on a physical strength and temperature variation. Therefore, there is a problem for using as the pipe material. In addition, in the case of the virgin grade, it satisfies the compression strength and tension strength as a pipe material, so that a recycling product occurring during the fabrication process is disserted. Disclosure of Invention Technical Solution
[5] Accordingly, it is an object of the present invention to overcome the above problems and to provide a method for fabricating a composition having a high strength and high tensile property and chemical resistance property and an atmosphere
resistance property and environmental friendly characteristic by mixing a high-density polyethylene with a glass fiber.
[6] To achieve the above objects, there is provided a method for fabricating a polyethylene composition having a glass fiber, comprising the steps of a step for mixing a high density polyethylene (HDPE) of 65kg through 70kg and a maleate degeneration polyethylene having an initiator of 3kg through 5kg and for fabricating a base composition, a step for mixing the base composition and a glass fiber of 30kg through 35kg having silica, aluminum, magnesium, titanium, sodium, and boron oxide as a chemical composition for thereby fabricating a polyethylene composition, a step for adding an ultraviolet stabilization agent to the polyethylene composition, a step for extruding and forming a polyethylene composition added with the ultraviolet stabilization agent at 210 ° C through 230 ° C, and a step for cooling the extruded and formed composition and cutting the same into a pellet shape for thereby fabricating a polyethylene composition having a high strength, high tensile property, good atmosphere resistance property and good chemical resistance property.
[7] In the step for forming the base composition, the initiator is formed of a di- alkylperoxide.
[8] To achieve the above objects, there is provided a polyethylene composition having a glass fiber that is characterized in that a high density polyethylene (HDPE) and a maleate degeneration polyethylene having an initiator are mixed for thereby fabricating a base composition, and the base composition is mixed with a glass fiber having a chemical composition formed of silica, aluminum, magnesium, titanium, sodium, and boron oxide, and an ultraviolet stabilization agent is added to the polyethylene composition, and a glass fiber is extruded and formed at 210 ° C through 230 ° C by adding an ultraviolet stabilization agent to the polyethylene composition and is cut and cooled for thereby fabricating a glass fiber having high strength, high tensile property, good atmosphere resistance property, and good chemical resistance property.
[9] In addition, in the base composition, the initiator is formed of a dialkylperoxide.
[10] Therefore, in the present invention, it is possible to fabricate a composition having a high strength, high tensile property, good chemical resistance property, good atmosphere resistance property, and good environmental friendly property. The present invention may be well adapted to a pipe material and an architecture material and may be added to the recycling products for thereby decreasing a fabrication cost. Description of Drawings
[11] The preferred embodiments o the present invention will be described with reference to the accompanying drawings.
[12] Egure 1 is a block diagram of a method for fabricating a polyethylene composition containing a glass fiber according to the present invention. Best Mode
[13] The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[14] Egure 1 is a block diagram of a method for fabricating a polyethylene composition containing a glass fiber according to the present invention.
[15] As shown therein, in order to form a base composition, a high-density polyethylene (HDPE) and a maleate degeneration polyethylene are mixed.
[16] The high-density polyethylene has a very large molecular weight in a range from a few thousands to a few millions. A physical characteristic such as an impact strength, heat resistance strength, environmental resistance stress breakage property, tensional property, etc. is enhanced compared to a low-density polyethylene (LDPE). In addition, a high-density polyethylene has a high structural crystalline property and has a very small number of tertiary. Therefore, safety with respect to oxidation is very stable.
[17] The maleate degeneration polyethylene (PE graft copolymer) is a kind of copolymer obtained by chemically coupling an anhydrous maleate monomer having polarity based on a polyethylene as base with a catalyst. In addition, the maleate degeneration polyethylene is preferably used by adding a dialkylperoxide as an initiator for thereby expediting a polymerization between maleate and polyethylene. The maleate degeneration polyethylene has an excellent adhesive property with other metals or plastic. Therefore, it is generally used as an adhesive layer with polyethylene and other plastic.
[18] Therefore, the high-density polyethylene of 65kg through 70kg is mixed with the maleate degeneration polyethylene of 3kg through 5kg and is used as a base composition. In this case, it is possible to enhance an adhesive property of the high- density polyethylene and to inhibit the coupling property with glass fiber that will be mixed.
[19] Next, the base composition obtained by mixing the high-density polyethylene with the maleate degeneration polyethylene is mixed with the glass fiber of 30kg through 35kg for thereby fabricating a polyethylene composition.
[20] The glass fiber has a chemical composition of silica, aluminum, magnesium,
titanium, sodium, boron oxide, etc. The composition ratio is as follows.
[21] Table 1
[22] As shown in the above table, according to the composition ratio, the glass fiber is a non-alkali glass and has an excellent electric insulation property, heat resistance property, good wind resistance property and excellent strength. In particular, B O 2 3 (oxide boron) is added for thereby enhancing tensional strength and a surface strength of glass fiber. In addition, in the case that it is used by mixing with architectural material and pipe material, an adiabatic heat keeping property is enhanced, and the viscosity coefficient is increased at a high temperature for thereby implementing an easier process. A chemical durability is enhanced. It also has a discontinuous property and has a small absorption. The physical characteristics of the above glass fiber are as follows.
[23] Table 2
[24] Next, an ultraviolet ray stabilization agent is added to a polyethylene composition mixed with a high-density polyethylene, maleate degeneration polyethylene, and glass fiber. The ultraviolet ray stabilization agent is capable of preventing discoloration and dissolution by ultraviolet rays for thereby improving an atmosphere resistance property of the product. Generally, there are known benzophenone, benzotriazole, pindideamine photo stabilization agent (HALS). The above element may be used in single or in combination.
[25] An ultraviolet stabilization agent is added to the polyethylene composition, and the polyethylene composition is extruded and formed as a thin fiber at a rate of 3m through 4m per minute by a twin screw at 210 ° C through 230 ° C. The polyethylene composition formed of a fiber is cooled using cooling water or air and is cut in a shape of pellet for being well mixed with an architectural material or pipe material.
[26] The polyethylene composition containing a glass fiber of a pellet type may be added to an architecture material or pipe material based on the purpose of use for thereby implementing a desired material having a high strength, high durable property, chemical resistance property, atmosphere resistance property, and environmental friendly property.
[27] In addition, in the case that the polyethylene composition is used only for a recycling source material, since the physical property is largely decreased, the above composition may be added to the recycling products for thereby enhancing a compression property, tensional strength and heat resistance property and preventing a twisting, so that the waste and discarded products may be recycled.
[28] The following is the test data of the physical property in the case that the glass fiber is added to the high-density polyethylene by volume ratio of 30%.
[29] Table 3
[30] As shown in the above table, in the case that the glass fiber is added to the high density polyethylene by the volume ratio of 30%, it is known that it is possible to obtain a high strength, high tensile property, and good chemical resistance property.
[31] As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims. Industrial Applicability
[32] As described above, in the present invention, it is possible to fabricate a polyethylene composition containing a glass fiber that is known to have a high strength and high tensile property, good chemical resistance property, good atmosphere resistance property, and environmental friendly property, etc. The glass fiber according to the present invention may be added to a pipe material or architecture material.
[33] In addition, the polyethylene composition having a glass fiber according to the present invention is added to the recycling materials, so that it is possible to enhance a compression strength, tensile strength, and heat resistance property and to prevent torsion of the product. Therefore, it is possible to effectively recycle the waste products, so that the fabrication cost is decreased.
