Description

Manufacturing method of booth materials for eco-friendly exhibitions and booth materials for eco-friendly exhibitions manufactured through the same

The present invention relates to a method for manufacturing an eco-friendly exhibition booth material and an eco-friendly exhibition booth material manufactured thereby, and more specifically, to an eco-friendly exhibition booth material obtained by melting recycled plastic, mixing zirconia powder, and molding the surface of a primary booth material obtained by high-speed polishing with high-temperature sodium silicate and then washing, and a manufacturing method thereof.

In general, plastics are considered as the main culprit of environmental pollution due to their high carbon emissions and long decomposition period.

On the other hand, a plastic profile is a type of square material made of plastic as a main material. It is widely used in areas requiring ease of management and assembly while applying a high load, such as warehouse shelves, by utilizing the characteristics of plastic, which has relatively excellent strength compared to its low weight. Standardized plastic profiles are recently in the limelight because they are easy to manufacture simple facilities based on them. In particular, plastic profiles are also used to form exhibition booths, and unlike general buildings, due to the nature of exhibition booths that operate for a relatively short time, plastic profiles that can be easily assembled and dismantled while maintaining the level of robustness required for exhibition booths are in the spotlight.

However, when a plastic profile is used as a material for an exhibition booth, one of the required properties is shape retention, which is due to the fact that, apart from the load capacity of the material itself, the plastic profile structure that is fixed using a fixing member may change its initially formed shape as it is continuously exposed to the use environment unless a sufficient level of fixing is made according to the characteristics of the plastic profile structure that is fixed using the fixing member. Problems with poor quality can arise.

Therefore, in the technical field to which the present invention belongs, there is a growing demand for a plastic profile that can provide sufficient fixing force even if an additional fixing member is not used for a plastic profile used as a material for an exhibition booth. As the reusability of the plastic profile is increased through its introduction, there is a demand for overall energy saving and prevention of environmental pollution through it.

An object of the present invention is to provide a manufacturing method of an eco-friendly exhibition booth material and an eco-friendly exhibition booth material manufactured through the same, and specifically, to provide a first booth material obtained by melting recycled plastic, mixing zirconia powder, and then molding the surface of the first booth material. It is to provide a booth material for an eco-friendly exhibition obtained by high-speed polishing with sodium silicate and then washing, and a manufacturing method thereof.

Another object of the present invention is to provide an eco-friendly exhibition booth material with enhanced surface friction by melting recycled plastic, mixing zirconia powder, and then molding the surface of the primary booth material obtained by high-speed polishing with high-temperature sodium silicate and then washing to provide a booth material and a manufacturing method thereof.

The problems to be solved by the present invention are not limited to the problems mentioned above, and the problems to be solved by the present invention that are not mentioned are those having ordinary knowledge in the technical field to which the present invention belongs from the following description (hereinafter "ordinary technician") will be able to clearly understand.

A method for manufacturing an eco-friendly exhibition booth material according to the present invention provided to achieve the above technical problem includes a first step of heating waste plastic to remove impurities and forming molten plastic; A second step of mixing zirconia powder with the molten plastic, pouring it into a mold and cooling it to room temperature to obtain a mixed plastic; A third step of obtaining a primary booth material by molding the cooled mixed plastic; A fourth step of high-speed polishing the primary booth material using sodium silicate; may include.

According to the present invention, as an eco-friendly exhibition booth material obtained by mixing zirconia powder with molten waste plastic and then molding the mixed plastic obtained by casting, the light weight and strength of the conventional plastic profile through additional physical and chemical treatment are maintained, while surface friction is increased to have a much higher fixing force, thereby providing a method for manufacturing an eco-friendly exhibition booth material with high reusability and an eco-friendly exhibition booth material manufactured through this.

The effect according to the present invention is not limited to the above, and the obvious effect according to the present invention that can be recognized by a person skilled in the art and the effect of adding or changing the configuration in the range of maintaining the same as the problem solving principle of the present invention is also intended as an effect according to the present invention, and a person skilled in the art will be able to recognize the effects according to the present invention without great difficulty.

According to one aspect of the present invention, the manufacturing method of the eco-friendly exhibition booth material according to the present invention,

A first step of heating the waste plastic to remove impurities and form molten plastic; A second step of mixing zirconia powder with the molten plastic, pouring it into a mold and cooling it to room temperature to obtain a mixed plastic; A third step of obtaining a primary booth material by molding the cooled mixed plastic; A fourth step of obtaining an exhibition booth material by high-speed polishing the primary booth material using sodium silicate;

In one embodiment of the present invention, waste plastics are plastics that have lost commercial value collected in various ways, and may include, for example, plastic toys, straws, and the like, and may include, but are not limited to, various waste plastics. It refers to waste plastics from which impurities are removed through heating and molten plastics can be obtained.

In one embodiment of the present invention, zirconia is zirconium dioxide, which melts at a high temperature of 2700 ° C. or higher, and has low thermal conductivity and excellent mechanical strength. Even when zirconium in powder form is mixed with molten plastic, it can maintain its powder form without melting. When zirconia is separated from plastic, pores may be formed on the plastic surface, so that excellent frictional performance may be imparted to the plastic surface even after zirconia is removed.

In one embodiment of the present invention, the sodium silicate may be a liquid sodium silicate composition, and the liquid sodium silicate composition is a composition comprising sodium oxide and silicic acid in water, and the weight percent of the sodium oxide and silicon dioxide in water is preferably 14 to 15 and 34 to 36, respectively. When the weight % of the silicon dioxide in the water exceeds 36, it is observed that the viscosity of the liquid sodium silicate composition increases more than necessary, so that kneading in the subsequent process step does not proceed easily. Suitably, the lower limit of the weight percent of silicon dioxide is 34.

In one embodiment of the present invention, the primary booth material may be high speed polished using sodium silicate. In this case, a porous polishing material impregnated with sodium silicate, for example, a silicon sponge, may be used, and the surface of the primary booth material may be polished using a known surface polishing means such as bead blasting before high-speed polishing with sodium silicate. The bead blasting is a physical polishing method in which various fine particles such as fine glass particles and fine metal particles are sprayed onto the surface of an object to be polished at high pressure and high speed using a gas or liquid to polish the surface or remove impurities from the surface. In order to have a higher effect on surface treatment by subsequent chemical polishing, it is preferable to use fine glass particles, which may be appropriately selected according to the surface roughness of the object to be polished. After this high-speed polishing, the primary booth material can be surface-cleaned by various means such as high-pressure water washing and ultrasonic washing.

According to another aspect of the present invention, a method for manufacturing an eco-friendly exhibition booth material according to the present invention includes a first step of heating waste plastic to remove impurities and forming molten plastic; A second step of mixing zirconia powder and quartz glass powder with the molten plastic, pouring the mixture into a mold, and cooling to room temperature to obtain a mixed plastic; A third step of obtaining a primary booth material by molding the cooled mixed plastic; It may be a method for manufacturing an eco-friendly exhibition booth material including a fourth step of obtaining an eco-friendly exhibition booth material by high-speed polishing the primary booth material using sodium silicate at 50 to 60 ° C.

In one embodiment of the present invention, the quartz glass powder is a glass made of silicon dioxide, which has excellent durability and a high melting point. When mixed with zirconia powder in molten plastic, it is ruptured in a subsequent polishing process. Through this, it can play a role of imparting higher friction to the surface of plastic materials used as booth materials for eco-friendly exhibitions.

According to another aspect of the present invention, a method for manufacturing an eco-friendly exhibition booth material according to the present invention includes a first step of heating waste plastic at 100 to 200 ° C to remove impurities and form molten plastic; A second step of mixing zirconia powder and quartz glass powder with the molten plastic, pouring the mixture into a mold, and cooling to room temperature to obtain a mixed plastic; A third step of obtaining a primary booth material by molding the cooled mixed plastic; It may be a method for producing an eco-friendly exhibition booth material comprising a fourth step of obtaining an eco-friendly exhibition booth material by high-speed polishing the primary booth material using sodium silicate at 50 to 60 ° C.

In one embodiment of the present invention, the waste plastic can be heated to 100 to 200 ° C. to remove various impurities included in the conventional waste plastic through combustion, and smooth internal convection is formed. Since the zirconia powder and quartz glass powder mixed therein can be relatively uniformly distributed, the temperature at which the waste plastic is heated and maintained is preferably 100 to 200 ° C.

In one embodiment of the present invention, the zirconia powder may be mixed at 10 to 20% by weight, preferably 12 to 18% by weight, more preferably 13 to 17% by weight, and more preferably 14 to 16% by weight based on 100% by weight of the molten plastic. In addition, the quartz glass powder may be mixed at 10 to 20% by weight, preferably 12 to 18% by weight, more preferably 13 to 17% by weight, and more preferably 14 to 16% by weight based on 100% by weight of the molten plastic. Meanwhile, when included together, the zirconia powder and the quartz glass powder may be 30% by weight or less based on 100% by weight of the molten plastic. When the zirconia powder is contained within the above numerical range, the useful effects according to the present invention can be further maximized, and in particular, the hardness of the product can be maintained while providing sufficient frictional force to the surface of the finally obtained product. When the quartz glass powder is contained within the above numerical range, the useful effects according to the present invention can be further maximized, and in particular, the hardness of the product can be maintained while providing sufficient frictional force to the surface of the final product, and the sum of the contents of the zirconia powder and the quartz glass powder is within the above numerical range. Depending on the inclusion, the mechanical properties of the final product can be maintained at an equal or enhanced level compared to conventional plastic profile products.

In one embodiment of the present invention, the average particle diameter of the zirconia powder may be 500 to 2000 micrometers, and the average particle diameter of the quartz glass powder may be 500 to 2000 micrometers. When the average particle diameter of the zirconia powder is within the above numerical range, the mechanical properties of the finally obtained eco-friendly exhibition booth material can be maintained at an equal or enhanced level compared to those of the conventional invention, and the average particle diameter of the quartz glass powder is within the above numerical range. By virtue of being within the above numerical range, the mechanical properties of the finally obtained product can be maintained at an equal or enhanced level when compared to conventional plastic profile products.

Hereinafter, the present invention will be explained in more detail using the following examples. Process conditions and preparation steps that are not specified in the following examples may be process conditions or preparation steps that are obvious in the art to which the present invention belongs, and a person skilled in the art can select them without difficulty based on the present disclosure to reproduce the problem solving principle of the present invention.

Step S2: Formation of Mixed Plastics

Based on 100% by mass of molten plastic placed in a ceramic mold, 15% by mass of zirconia powder and 15% by mass of quartz glass powder were mixed and mixed. The average particle diameters of the zirconia powder and the quartz glass powder were each 1000 micrometers. Stirring was continued until the mixed plastic was sufficiently solidified so that the zirconia powder and the quartz glass powder did not precipitate. After the mixed plastic solidified, it was maintained.

Step S3: Formation of primary booth materials

The solidified mixed plastic was melted and molded to prepare a plastic profile in the form of an octa profile. After cooling to room temperature, zirconia particles and quartz glass particles exposed on the surface were confirmed.

Step S4: Polishing, anodizing and sealing to obtain eco-friendly exhibition booth materials

The object to be polished was placed in a chamber in a bead blaster, and the surface was evenly polished for 15 minutes using glass beads having a size of 0.150 to 0.250 mm. An abrasive object having a surface with little light reflection was provided. Then, the polishing object was washed with tap water. Thereafter, an aqueous sodium silicate solution was prepared to spray the high-temperature sodium silicate aqueous solution at high pressure. A sodium silicate aqueous solution was prepared using 70 kg of water, 30 kg of silica, and 15 kg of sodium oxide and heated to 60 °C. The object to be polished was placed in a spray chamber and the sodium silicate aqueous solution was evenly sprayed for 10 minutes using a high-pressure sprayer at a distance of 30 cm. Afterwards, the residual sodium silicate aqueous solution was blown off using compressed air. An abrasive article having a slight surface gloss was provided.

Experimental Example 2: Preparation of eco-friendly exhibition booth materials of Examples 2 to 5

As shown in Table 1 below, by varying each component, eco-friendly booth materials for exhibitions were obtained as described in steps S1 to S4.

Example 2 did not include the quartz glass powder in order to evaluate the effect of the finally obtained eco-friendly exhibition booth material according to whether or not the quartz glass powder was included.

Example 3 did not include zirconia powder and quartz glass powder in order to evaluate the effect of the finally obtained eco-friendly exhibition booth material according to whether or not zirconia powder and quartz glass powder were included.

[Table 1]

The booth materials for eco-friendly exhibitions according to Examples 1 to 3 were each molded in the form of three 1m standard octa profiles, and also molded as three 0.5m standard plastic profile squares that can be connected thereto. The plastic profile angle member was connected to the octa profile, fixed using one L-shaped fixing member and the same number of bolts and nuts at the same location, and then the degree of load capacity was displayed on a 5-point scale, and then the total was displayed. In addition, the plastic profile angle member was connected to the octa profile, maintained without fixation using a separate member, then the octa profile was erected vertically on the ground and strongly fixed, and then the plastic profile angle member was placed at a height of 0.3 m from the ground. Then, the degree of slip was evaluated while moving at a constant speed in the range of 0.2 m up and down in the vertical direction from the ground. The case with the highest slip resistance was indicated as 15, and the case of falling to the ground when the plastic profile angle member was not fixed was indicated as 0.
