Description
The present invention relates to a foamed glass insulation material manufacturing method and the foamed glass insulation material, in particular a method for producing a foamed glass insulation material and excellent foaming performance and physical properties while using a microwave and boiling method significantly reduced the manufacturing cost and foamed glass It relates to a heat insulating material.
The method of manufacturing the insulation material using the powder of waste glass or common glass is to make the porous silica material by foaming glass powder to have insulation. However, since glass powder itself is difficult to foam, it has been utilized to make foamed glass and commercialize it as a heat insulating material by applying a method of foaming by mixing with other materials that melt and rapidly expand its volume.
Existing products that have been commercialized and sold to date are products produced by mixing carbon in glass powder, melting it, and then foaming it.
Therefore, many investments and costs such as the energy cost of heating up to the temperature at which the glass starts to melt and the heating device required are very expensive. Therefore, the production cost is very expensive and it has been used and applied only for special purposes. The market for foam glass insulation has not expanded.
However, the production and use of organic insulating materials, such as styrofoam and foamed polyurethane, which have been widely used in accordance with the increasingly demanded use of eco-friendly products and the full-fledged implementation of the Kyoto Protocol, are prohibited. The need for thermal insulation materials made of environmentally friendly inorganic materials has risen rapidly. Insulation materials have been used most often as building materials, and they are also widely used as wall insulation materials such as refrigerators. Insulation materials made of organic materials are still used, but they do not decompose in the ground for hundreds of years and pollute the environment. Due to the aforementioned reasons, the development of an insulation made of an inorganic material has emerged as an urgent problem, and in particular, the need for the development of an inorganic material made of an inexpensive material is required.
From this point of view, among the inorganic insulating materials that can replace the existing organic insulating materials, the foam glass insulating material is being researched as the closest alternative, but the foamed glass insulating product produced by the conventional melting method is very expensive. It has been a major obstacle to economic utilization and utilization in industrial sites where demand is a demand.
Conventional molten glass foam is a method of foaming by mixing carbon into glass powder and foaming by carbon to increase the volume, which requires a high temperature process of at least 600 degrees Celsius, which requires a lot of energy. The price was inevitable.
In addition, the existing molten foam has to be quenched in the molten state can be solidified without reducing the volume caused by the bubble was required a huge facility cost.
In order to solve the above problems, the present applicant (inventor) has developed and filed a patent application No. 10-2011-0098207 (filed on September 28, 2011). As in the previous application by the applicant, it was possible to express a desired strength by mixing and foaming water glass as a crosslinking agent for increasing the bonding force between the glass powder particles to express the strength of the product. Particularly, in order to express hydrophobicity, closed bubbles should be formed inside the product by appropriately controlling bubbles generated during foaming. However, in the ordinary boiling method, open pores are formed to act as capillaries, so that moisture gradually penetrates into the interior, resulting in poor thermal insulation performance. It has been difficult to functionalize and commercialize as a thermal insulation product due to the destruction of the mesh structure or the network structure, and this problem was solved by using an antifoaming agent in the previous application.
However, in order to produce a product using the above-described patent application technology, the maximum production yield should be maintained, but it was difficult to implement an easy and precise bubble control technique necessary to maximize the production yield required for mass production only by using an antifoaming agent.
Referring to FIG. 1, when foaming a mixed solution of glass powder + water glass + water + antifoaming agent according to the applicant's prior patent application, as shown in FIG. Phenomenon often occurred, and in order to solve this problem, it had to be produced considering various factors in consideration of the shape of the container and internal pressure. This resulted in the glass powder sinking under foaming, which caused the uneven distribution of bubbles due to the air bubbles upward. The product in which this phenomenon occurs is partly made of a poor product that the strength of the product is weakened or the insulation properties are not evenly expressed.
Referring to FIG. 2, as a method of improving the method of FIG. 1, foaming is performed by raising the internal pressure of the foaming container according to the applicant's prior application patent technology, bubbles are relatively evenly distributed, but there are still difficulties in commercialization. This is because the glass still sinks as shown in FIG. 1.
An object of the present invention for solving the above problems, by applying a method that can produce a foam glass insulation material more easily and inexpensively, the field application of environmentally friendly inorganic materials by significantly lowering the cost and production cost of the product In addition, it improves the usability and reduces the environmental pollution by replacing the use of organic insulating materials. Especially, bubbles of appropriate size are formed inside the foam glass insulating material, and closed pores are formed through this to express hydrophobicity, and at the same time, the pores are formed evenly throughout the product. The present invention provides an easy and precisely improved foam glass insulation bubble control method which is essential for mass production of foamed glass insulation material by mass-producing foamed glass insulation material by using the boiling method of waste glass powder to have uniform strength by distribution.
Another object of the present invention for solving the above-mentioned problems is, according to the above-described object of the foam glass insulation material improved through the manufacturing method of the foamed glass insulation material is very excellent in the performance of the insulation material, but the economical efficiency of the mass production excellent foamed glass material In providing insulation.
Foamed glass insulation manufacturing method of the present invention for achieving the above object, in the foamed glass insulation manufacturing method, preparing a glass powder of 60 ~ 100㎛; Mixing the glass powder, water in a predetermined ratio, 10-30 vol% of liquid sodium silicate, a predetermined silicone antifoaming agent, and a predetermined surfactant; And placing the mixture in an airtight container and injecting microwaves to dry the foamed glass after boiling for a predetermined time.
Here, in the mixing step, the surfactant is added in a ratio of 1 ~ 10Volume%, the antifoaming agent is more preferably added by mixing in a ratio of 0.1 ~ 5Volume%.
Foamed glass heat insulating material of the present invention for achieving the above-mentioned other objects, glass powder of 0 ~ 100㎛, water of a predetermined ratio, 10-30 volume% liquid sodium silicate, 0.1-5 volume% silicone-based antifoaming agent and , 1 to 10% by volume of the surfactant is mixed, the mixture is contained in a sealed container and injected with microwaves of a predetermined frequency, characterized in that the foamed glass insulation prepared by drying the foamed glass after boiling for a predetermined time (boiling).
Foamed glass insulation manufacturing method using the boiling method of the present invention and the foamed glass insulation according to the above, the foamed glass insulation material which is excellent in performance and significantly reduced manufacturing cost through a simple manufacturing method at a very low temperature compared to the conventional production . In particular, the method according to the present invention is a method of applying the antifoaming agent to control the size and distribution of the bubbles in the process of boiling and foaming a mixture of glass powder, water glass (liquid sodium silicate) and water using a mycropa It is a method to control bubbles more smoothly and easily by improving the method of pre-application, and evenly distributes bubbles inside the product by adding surfactant which promotes the generation of bubbles and materials having opposite characteristics to suppress the generation of bubbles. At the same time, the bubbles are crushed finely so that the fine bubbles are evenly distributed inside the product, thereby providing the effect of simultaneously expressing hydrophobicity and strength.

Figure 3 is a product foamed by additionally added 5Volume% surfactant and 1Volume% antifoaming agent according to the manufacturing method of the present invention is evenly distributed from the bottom of the product to the top of the product evenly excellent strength is excellent performance Picture of the prototype of foamed glass insulation of
The method of manufacturing the boiling glass foam of the present invention obtained by the present inventors after the endless experiments and efforts is performed by mixing glass powder and water, and then expanding the volume by boiling water at 100 degrees Celsius. Continued heating greatly simplifies the process by evaporating the water contained in the water glass without the need for a separate cooler, naturally drying and solidifying in boiling.
In addition, the method of applying heat also generates heat by stimulating water molecules using microwaves with a frequency of around 2,450 MHz with an output of at least 1.5Kw, rather than an external heating method, thereby significantly reaching the required temperature of glass foam. It was shortened to allow the foaming process to be completed within a few tens of seconds. This process has the advantage that the foaming is evenly made by evenly boiling phenomenon as a whole, minimizing the energy cost.
However, the foamed glass insulation made only by this process has hydrophilicity, and when the surface of the insulation comes into contact with air or with the surface or water, water is absorbed and the network structure is gradually collapsed, thereby breaking or cracking as a whole. There are disadvantages of deterioration, and also, since the bonding strength between the glass particles as a whole is very weak compression and tensile strength has been difficult to develop. This is a basic property of the inorganic material is that the adhesion and bonding strength between the particles is weak, does not express the minimum strength required as a heat insulating material and also has a hydrophilic character.
Therefore, in order to further solve the problems caused by the properties of these materials, a crosslinking agent was used in the present invention. The crosslinking agent used in the present invention used liquid sodium silicate which is an inorganic material. Liquid sodium silicate is an inorganic material solution used for the adhesion of glass and is mixed with water and glass powder mixed sludge (preferably, 20 vol% water in one embodiment) of crosslinking agent liquid sodium 10-30 vol%. When the mixed sludge thus prepared is heated with microwaves, it can be seen that the mixed solution boils and the volume expands.
However, the foamed glass thus made has strength, but it has hydrophilicity, which causes problems in the long-term use. Also, since the size and distribution of bubbles existing in the insulation are not constant, there is a problem in producing foam insulation that exhibits uniform insulation performance. have. In addition, the size of the bubble should be kept as small as possible and controlled to be distributed innumerably in the material, so that the overall strength can be maintained while the heat insulation property is effectively expressed. In other words, a method for producing the foamed glass so as to maintain the specific surface area as large as possible was needed.
In order to further solve the problem, the above-described invention of the present applicant further applied an antifoaming agent. Antifoaming agent is a material that has the property of removing bubbles. It has the property of suppressing foaming, which is the opposite of the manufacturing characteristics of foamed glass, which expands well due to the high foaming volume. When applied within%, it suppressed a sudden boiling phenomenon and reduced the size of the bubble, so that the overall reduced size of the bubble evenly distributed from the bottom to the top of the material. In addition, by maintaining the size of the bubbles to be fine, it is possible to make a foam glass insulation having a natural hydrophobicity, it was possible to exert excellent thermal insulation properties by expanding the volume to at least three times as evenly distributed fine pores in a large amount.
Furthermore, the foamed glass bubble control method for mass production according to the present invention, in the process of boiling and foaming a mixture of glass powder, water glass and water using a predetermined microwave, in order to control the size and distribution of the foam to be foamed as well as a defoamer In addition, by adding a surfactant that promotes the generation of bubbles and a material having mutually opposite properties that suppress the generation of bubbles, the bubbles are evenly distributed inside the product, and the bubbles are broken finely so that fine bubbles are formed inside the product. By making it evenly distributed, by controlling the physical properties such as the distribution and strength of bubbles more easily and precisely, the hydrophobicity and strength were improved at the same time to enable mass production of foam glass insulation of excellent physical properties.
Hereinafter, looking at a preferred embodiment of the foam glass insulation manufacturing method using the boiling method according to the present invention.
First, glass powder (starting material) is prepared in one step. When waste glass is used for resource recycling and cost reduction, the collected waste glass is crushed in a ball mill or crusher to recover 60 ~ 100㎛ glass powder.
The second step is a mixing process (stirring process), mixing glass powder and water (preferably 20 volume%), mixing liquid sodium silicate as a crosslinking agent (10 to 30 volume%), and adding a silica-based antifoaming agent (0.1 to 5 volume) %), Add surfactant (1 ~ 10Volume%) and mix
The third step is a foaming process, in which the mixture is placed in an airtight container (chamber), and a glass powder mixture is foamed by injecting microwaves with a frequency of 2,450 MHz with an output of at least 1.5 Kw to stimulate water molecules to generate heat. After drying for a certain time, the foamed glass insulation shown in FIG. 1 according to the present invention is obtained.
In addition, step 4 is a heat insulation material commercialization process, by cutting the foamed glass insulation obtained in step 3 to a predetermined standard and packaging (in this case, by combining the plate by the standard on the outside surface), the standardization that can be immediately used in industrial sites Foamed glass insulation is completed.
3 is a prototype foamed in the manner according to the invention by the addition of 5% by volume of the surfactant and 1% by volume of the antifoam, it was confirmed that evenly distributed from the bottom of the product to the top of the bubble even enough strength.
Therefore, although the ratio of mixing the surfactant and the antifoaming agent varies depending on the required characteristics of the product or the particle size of the glass powder, the surfactant should be at least 1Volume% of the total mixed solution when foaming glass powder is used to produce the insulation product. If the antifoaming agent is applied at less than 0.1Volume% and at most 5Volume%, foamed glass insulation products using waste glass powder can be stably manufactured.
The method of mixing and applying the surfactant and the antifoaming agent is an optimization condition of the production of foamed glass which the inventors found very difficult under various experimental conditions, and it is possible to mass-produce the foamed glass insulation at a very simple and low temperature. The performance and production efficiency of the was further increased.
On the other hand, in order to analyze the physical properties of the foamed glass insulation according to the present invention, the specific gravity was tested by KS L 3114, the compressive strength was tested by KS F 2405 (HJ-3652 digital compressive strength tester), tensile strength KS F 2423 (Model AFT-DTT-100 Digital Tensile Strength Tester), and to measure the strength change, the specimen (sample or prototype) prepared according to the above 1, 2, 3, the specific gravity, compressive strength, tensile strength It measured in three cases.
Specific gravity is to dry the prepared sample in a thermostat at 110 ± 5 ℃, 8-12g of which is taken in a 50ml specific gravity bottle P (g) weighed in advance and weighed to P1 (g), About half of the distilled water was filled and the mass was P2 (g). The mixture was heated in a water bath to remove bubbles and cooled to room temperature. Distilled water was put here to the scale line, the mass was made into P3 (g), the mass when it became a quantity by the following formula was made into the dry mass W1 (g), and specific gravity was measured by the following formula.
D = (P1-P) / (P1-P)-(P3-P2), where P is the mass of the pycnometer (g), P1 is the mass (g) when the sample is placed in the pycnometer, P2 is distilled water in the pycnometer The mass (g) when filled with P3 is the mass (g) when the sample is placed in a specific gravity bottle and distilled water is filled to the graduation line.
The compressive strength was set so that the sample was mounted at the same speed so that the central axis of the sample coincided with the center of the pressure plate within an error of less than 1% of the sample diameter. In this case, the compressive strength was checked by increasing the compressive stress rate to 0.6 ± 0.4 MPa every second and using the maximum load indicated by the tester to three significant figures until the sample was destroyed.
Tensile strength was applied at the same speed so that there was no gap anywhere between the contact plate between the pressure plate and the sample, and the sample was not impacted. The rate of increase in tensile stress applied to the load was adjusted to 0.06 ± 0.04 MPa (= N / mm2) per second, and the rate of rm increase was maintained until the maximum load was reached. The tensile strength was confirmed by 3 significant figures.
According to this test method, the results of measuring the prototype of FIG. 1 and FIG. 2 according to the present invention, respectively, are shown in the following table.
As shown in the above table, both the compressive strength and the tensile strength of the product of FIG. 3 according to the present invention realize excellent properties compared to those of FIGS. 1 and 2, and also as shown in the prototype picture of FIG. It can be confirmed visually that it has a distribution chart.
