Description

Manufacturing method of light weight bubble cement using composition of light weight bubble cement}

The present invention relates to a method for manufacturing a lightweight foam cement foam using a lightweight foam cement composition, and more specifically, to form a foam structure of uniform size at room temperature using a general cement, and lightweight, soundproof and excellent insulation and moisture-proof effect and high temperature The present invention relates to a method for producing a lightweight foam cement foam using a lightweight foam cement composition which does not emit toxic gas and has excellent bonding force between foam structures.

In general, when manufacturing a foam ceramic or foam cement (ALC) requires a long curing process or high temperature.

Energy resources on the planet are limited and energy is essential in all sectors of homes, industrial production, transportation and commerce.

Therefore, it is important to reduce the limited energy saving and resource consumption on the planet, but also to reduce the loss and waste of energy.

About 30% of the energy consumed in Korea is used for heating and cooling of non-residential buildings, including residential and office buildings, and research and development on how to reduce energy waste through buildings is ongoing. One of them is energy consumption through walls. Or research and development of insulation materials to reduce waste.

On the other hand, noise affects psychologically, impairs thinking ability, disturbs rest and sleep and communication, and healthy daily life, and increases physiological fatigue, impatience, difficulty in mental concentration, energy consumption at work, Gastric fluid secretion, cardiovascular system, salivary secretion, autonomic nervous system, endocrine system and sleep are adversely affected. Therefore, insulation and sound insulation are used for walls of buildings.

The wall according to the prior art uses ceramic or foamed polymer material in which fine air cells (foamed tissue) are formed in order to enhance insulation and sound insulation or sound absorption, or a mixture of porous ceramics in which an air layer is formed and sound absorbing material that can absorb noise. The air layer can be formed by foaming or the like. Insulation and sound insulation according to an embodiment of the prior art is foamed polystyrene, glass, foamed polyethylene, polyurethane foam, vermiculite, perlite, urea foam, cellulose insulation, soft fiber plate, phenol foam, aerogel, lightweight cement And the like are common.

Foamed polystyrene has high insulation and light weight, and is excellent in transport and construction. However, since the maximum safe working temperature is 70 ° C., it is vulnerable to high temperature and ultraviolet rays and has a high risk of ignition or toxic gas in case of fire.

As for the glass surface, the air layer sealed between the glass fibers forms a heat insulation layer, and it has excellent incombustibility, sound absorption, workability, and transportability. Installation is required.

Foamed polyethylene is prepared by mixing and blowing a foaming agent and flame retardant in polyethylene resin, and laminating and fusion of a plate-shaped foaming agent cooled after extrusion foaming. It is manufactured as a heat insulating plate and a thermostat with self-extinguishing ability. Excellent but safe operating temperature is up to 80 ℃ and there is a problem of emitting toxic gases in the fire.

Polyurethane (polyol), polyisocyanate (foaming agent), foaming agent, additives for flame retardancy is the main raw material.

Polyurethane foam foam molded organic foam (independent bubble structure) has excellent heat resistance (100 ℃ maximum temperature) and heat insulation. Especially, it is widely used as a cold storage material for refrigeration equipment. In case of fire, there is a problem of toxic gas emission as in other foamed polymer materials.

Vermiculite is a mica-based ore, a porous, porous mineral fired at a temperature above 1000 ° C and has the advantage of insulation, insulation, non-combustibility, sound insulation, and condensation prevention.

Perlite is calcined and expanded by calcining pearl stone of volcanic stone at 900 ~ 1200 ℃, and it is formed of light spherical small particles with micropores inside and is used as light weight aggregate and heat insulating material. However, mineral foaming such as vermiculite and perlite, there is a problem that requires a high energy of 1,000 ℃ or more.

Aerogels have a ten thousandth thick hair structure, like cotton candy, which forms 95% of the entire volume as air holes, so it has excellent heat insulation and soundproofing effects, but is limited to some high-tech industries due to its relatively high cost.

Lightweight cement can provide economical foam by using inexpensive cement as a binder, but curing in high temperature and high pressure reactor (autoclave) has high economic burden on facility installation and high thermal energy to cure foamed cement. Is required, and there is a problem that takes a long time for curing of cement.

In particular, the lightweight cement is hard to take several days to several tens of days when it is directly applied to the foamed cement in the form of slurry that is not cured on the walls of building structures such as apartments. Cement cannot be provided, and since cement hardening and defoaming occur simultaneously, there is a problem in that the compressive strength is significantly lowered after hardening because the bond between the cement particles and the particles is broken.

If the foam material is a petrochemical product, it can cause fatal hazards by toxic gas emission in the event of fire and accelerate environmental pollution. Foam ceramics or lightweight foam cements require large-scale facility system, high temperature manufacturing process and long time processing process. In addition, since the construction work for insulation and soundproofing is placed on the work site, there is a problem of large energy loss and poor productivity and workability.

In particular, since foam ceramic uses a predetermined mold for compression molding, it requires a lot of equipment cost and there is a problem in that it is limited in price competitiveness using expensive raw materials such as aerogels.

Looking at the prior art data that has been researched and developed to solve the above problems, Korean Laid-open Patent No. 2006-0092782 (August 23, 2006) "ceramic foam molding and its manufacturing method" is pulverized foamed vermiculite, pearl rock, obsidian , Mixed with various foamed ceramic particles including pine stone, mixed with one or more inorganic adhesives including gypsum, cement, clay, sodium silicate, unfinished gel silicate, sodium silicate, etc. As a method for producing a ceramic foam molded article, which is manufactured by mixing steel fiber, fiber crushed snow, paper crushed product (including powder type), glass wool (glass wool), or by mounting a wire mesh or synthetic resin network inside, a method has been proposed.

In addition, Korean Laid-open Patent No. 2003-0086955 (2003.11.12.) "Manufacture technology of lightweight foamed concrete using expandable lightweight aggregate for the manufacture of non-combustible sandwich panel" is expanded vermiculite formed by heating natural vermiculite to high temperature And lauryl alkylbenzene sulfonate-based materials, which are surfactants, to adjust the air density to about 40 to 50 kg / cm 2, and the resulting bubbles, cement slurry, and expanded vermiculite are mixed so that they are not burned in a fire. Non-combustible lightweight foam concrete sandwich panel is proposed in consideration of building exterior wall finishing and insulation without gas emission.

Korean Laid-open Patent No. 2000-0060707 (October 16, 2000) “Sound absorbing soundproof panel using lightweight foam concrete” is a lightweight foam concrete obtained by curing with steam curing or high temperature and high pressure steam by adding foaming agent to cement, lime and siliceous fine powder. The soundproof panel which makes a sound absorption material is proposed.

The Korean Laid-Open Patent No. 2006-0092782 can provide heat insulation by an air layer included in ceramics, but in order to manufacture foamed ceramics, various rocks including natural materials such as vermiculite, pearlite, obsidian, pine stone, etc. are desired in size. Pulverized and heated to a high temperature of 800 ~ 1400 ℃ high thermal energy is required for the production of expanded ceramics, there is a disadvantage that requires a lot of equipment costs, this also in the foamed ceramic particles gypsum, cement, clay, silicic acid Since it is only a mixture of inorganic adhesives including soda, unfinished gel silicate, sodium silicate cement, etc., there is a problem that it cannot be poured directly at the construction site.

The Korean Laid-Open Patent No. 2003-0086955 provides excellent foaming power by surfactants and economics by using cement as an inorganic binder. However, the curing time for forming a hardened body of lightweight cement is described in the embodiment. This takes a long time for one to two days, which leads to a drop in productivity, and when it is placed on the wall of the building structure using the proposed method, it does not harden immediately, so it flows down to the floor immediately after pouring and cannot be poured directly at the construction site. there is a problem.

The Korean Laid-open Patent No. 2000-0060707 can provide a light weight concrete having a porosity, and may have an excellent sound absorption effect. However, the foamed concrete is cured by steam curing or high temperature and high pressure steam, and thus the installation cost of huge equipment required for curing and There is a problem of inadequate economy because it requires operating costs and a lot of time for the curing process, there is a problem that can not be directly poured in the construction site because it does not harden immediately after placing on the wall.

Therefore, it is necessary to develop a lightweight cement manufacturing technology using general cement, forming a foam having a uniform foam structure at room temperature, requiring a short curing time, generating no toxic gas even at a high temperature, and having excellent bonding strength between the foam structures.

In order to solve the problems and necessity of the prior art as described above, the present invention uses general cement to reduce the manufacturing cost and to foam and harden at room temperature, thereby reducing the cost of manufacturing facilities and shortening the curing time to increase productivity and workability. Provides a method for producing a lightweight foam cement foam using environmentally friendly lightweight foam cement composition does not generate toxic gases even at high temperatures.

Cement can be broadly classified into hard cement which hardens only in air and hydraulic cement and special cement which harden in air and water. Portland cement, which is called general cement, is classified as hydraulic cement.

Portland cement is in accordance with KS L 5201 standard and includes one ordinary cement, two medium heat cements, three crude steel cements, four low heat cements and five sulfate resistant cements.

Class 1 ordinary cement refers to general cement and is used for civil engineering and building construction.

The two types of heavy heat cements have a heat of hydration corresponding to the intermediate level between ordinary cements and low heat cements, and have a small dry shrinkage to prevent cracking and to promote long-term strength. They can be used for dam, tunnel, road pavement and runway construction.

Three kinds of crude steel cement has a fast hydration rate, which usually gives 28 days of strength in 7 days and has good strength at low temperatures, which can be used for emergency construction, winter construction, subway construction, and production of concrete secondary products.

The 4 kinds of low heat cement are excellent in temperature crack control due to low heat of hydration, high flowability and high strength. They are used for LNG underground storage tank, large buildings including underground continuous wall, and mass concrete construction in various fields. Can be.

The five types of sulfate-resistant cements are resistant to sulfates by minimizing acidic components among cement components, which are highly chemically stable and have excellent strength, so that they contain sulfate-rich soils, groundwater, and river structures, factory wastewater facilities, It can be used for nuclear reactors, harbors, marine works, and the like.

General Portland cement is composed of 200 to 270 parts by weight based on 100 parts by weight of water, it is most preferable to provide a water: general Portland cement in a weight ratio of 1: 2.44.

When the general portland cement is mixed with more than 270 parts by weight, the size and number of foam structures are reduced, so that the weight per unit area is rather increased.

On the other hand, when the general portland cement is composed of less than 200 parts by weight of the mixing, there is a problem that the foam structure is formed non-uniform and the final foam is easily broken.

Cemented carbide cement expresses 7-day strength of ordinary cement in 2 ~ 3 hours, has rougher strength than alumina cement, and can be mainly used for road, bridge emergency repair, mechanical foundation work, Korea-China construction and concrete secondary product manufacturing. have.

Carbide cement is provided with 25 to 35 parts by weight based on 100 parts by weight of water, water: cemented cement is preferably provided in a weight ratio of 1: 0.271.

In the case of mixing (injecting) cemented carbide with more than 35 parts by weight of the cement, the curing proceeds rapidly, but the foam structure is not uniform, and the composition of each component is not smooth and partially agglomerated, thus reducing the overall rigidity. There is.

On the other hand, when the cemented carbide having 25 parts by weight or less is provided and mixed, there is a problem in that hardening effect is hardly exhibited.

Calcium carbonate (CaCO3) is a calcium carbonate, the main component of chalk used in blackboard, insoluble in water, and used as one of the raw materials of cement.

Calcium carbonate may be provided in an amount of 4 to 7 parts by weight based on 100 parts by weight of water, but water: calcium carbonate is preferably provided in a weight ratio of 1: 0.542.

Calcium carbonate has the effect of increasing the porosity of the final cured cement product, and when added below 4 parts by weight, there is a problem that the porosity does not increase, and the added amount when added above 7 parts by weight There was no effect change compared to

Hydrogen peroxide (H 2 O 2) is used as a bleach, an oxidizing agent and the like and is provided with 20 to 25 parts by weight with respect to 100 parts by weight of water, it is preferable to include water: calcium carbonate in a weight ratio of 1: 0.213.

When the hydrogen peroxide is added below 20 parts by weight, the bleaching effect of cement is hardly observed, and when it is added above 25 parts by weight, there is almost no change in bleaching due to the increase of the input amount.

Calcium (Ca) is provided with 2 to 3.5 parts by weight based on 100 parts by weight of water, it is preferable to provide water: calcium in a weight ratio of 1: 0.027.

Calcium has a function of promoting foaming, and when it is added in the above 3.5 parts by weight, there is almost no change in the foaming promotion with respect to the increase of the input amount. have.

The fiber may be provided in an amount of 0.5 to 1 parts by weight based on 100 parts by weight of water, but water: fiber is preferably provided in a weight ratio of 1: 0.008.

The fibers can use both plant fibers and chemical fibers, which act to prevent cracking of lightweight foam cement, and can range from 5 to 7 millimeters (mm) in thickness ranging from 3 to 50 micrometers (um). It consists of a length.

Physical properties according to an embodiment of the fiber commonly used in the present invention are shown in Table 1 below, and all kinds of fibers satisfying these physical properties may be used.

Density (g / cm * 3) Diameter (um) Length (mm) Tensile Strength (MPa) Modulus of elasticity (GPa) 0.97-1.3 3-50 5-7 1600-2500 37-75

When the fiber is added in an amount of more than 1 part by weight, some of the final fibers may not be smoothly mixed and aggregated. There is a small problem.

When the fiber is added at 0.5 parts by weight or less, there is a problem in that the finished lightweight foam cement is easily broken in a small impact.

The coarse agent is also called E.S.A (Early Strength Admixture) and has 8 to 9 parts by weight with respect to 100 parts by weight of water, and water: it is preferable to have a coarse agent in a weight ratio of 1: 0.0818.

Roughening agent (E.S.A) consists of calcium chloride, triethanolamine, calcium nitrite, etc., and acts to harden hydraulic cement quickly.

When additionally adding (injecting) the crude agent to the above-mentioned 9 parts by weight or more, it hardens quickly, but there is a problem such as poor workability and reduced efficiency compared to the cost required, and when added below 8 parts by weight. There is a problem that the curing time takes too long without feeling the added effect.

Carbon is provided with 15 to 17 parts by weight with respect to 100 parts by weight of water, it is preferable to include water: carbon in a weight ratio of 1: 0.182. Carbon is organic carbon and inorganic carbon, but both can be used, it is preferable to use a low specific gravity.

Carbon is used as a chemical reaction accelerator and when the amount is added in excess of 17 parts by weight, the reaction is not accelerated in proportion to the amount added in excess. It is confirmed that it is difficult to do.

The polymer (polymer or mortar powder) is provided in 1 to 2 parts by weight with respect to 100 parts by weight of water, it is preferable to provide a water: polymer 1: 1 0.0164 weight ratio.

Silica fume may be provided in an amount of 1 to 2 parts by weight based on 100 parts by weight of water, and water (silica fume) is preferably added (added) in a weight ratio of 1: 0.016.

Silica fume improves the durability and strength of cement to a very high degree and is used as part of the binder and is relatively expensive. When the silica fume is added in an amount of 2 parts by weight or more, the change in durability and strength does not appear to be improved any more, and the cost is high. Didn't show up.

The water reducer is added (added) at 0.5 to 1 part by weight with respect to 100 parts by weight of water, and it is preferable to configure (inject or add) the water: reducing agent at a weight ratio of 1: 0.0064.

The water reducing agent is a mixed material which reduces the capacity of the mixing water required for cement and promotes condensation (solidification or curing), and may be used by selecting any one of ligrin sulfate, hydrous carbon, and HYDROXYLATED CARBOXYLIC-ACID.

In the case where more than 1 part by weight of the water reducing agent is added, the effect of further improving the condensation of the light-foamed cement foam is drastically reduced, and in the case where the amount of the reducing agent is less than 0.5 part by weight, the effect of improving the condensation is hardly seen. Therefore, the water reducing agent was preferably added (added) at 0.5 to 1 part by weight based on 100 parts by weight of water.

The phenic mineral is added (constituted or added) at 0.5 to 1 parts by weight based on 100 parts by weight of water, and water: phenic mineral is preferably added (constructed or added) at a weight ratio of 1: 0.0064. The phenic mineral is a mineral containing iron (F) and magnesium (Mg), which includes wollastonite and calcite, and acts to brighten the color of the lightweight foam cement foam. It did not improve, and the case of adding below 0.5 weight part did not improve.

Water was based on the use of general tap water, but there was no significant difference in the composition ratio of each composition even when other types of water were used.

≪ Embodiment 1 >

The composition ratio of each composition constituting the lightweight foam cement foam was provided as a first example as shown in Table 2 below in units of weight (Kg).

When mixing each composition as described above: can be produced lightweight foam cement foam in a state capable of filling the mold or mold for forming the width: length: 1 m (m) each.

Second Embodiment

1 is a flowchart of a method for manufacturing a light foam bubble cement foam using a light foam bubble cement composition according to an embodiment of the present invention.

With reference to FIG. 1, a method for producing a lightweight foam cement foam using the composition described in Table 1 above and blended according to the first embodiment will be described in detail.

Check that the preparation of the composition to prepare a light-foam cement foam (S1000).

The composition of the lightweight foam cement foam is a dry bibeam treatment of dry materials such as general Portland cement, cemented carbide, calcium carbonate, hydrogen peroxide, lithium carbonate, calcium, fiber, coarse, carbon, polymer, silica fume, water reducing agent, and femix minerals. S1100).

The time required for the dry bibeam is in the range of 10 to 20 minutes, and about 15 minutes is most efficient and desirable, and can be increased or decreased in proportion to the input capacity of the fiber.

Here, as another embodiment, silica fume may be excluded, and the process of including the silica fume will be described later.

20% by weight (%) of water prepared in the dry bibim-finished composition is added (mixed) and subjected to the first wet bibim treatment for any one time selected from the range of 10 to 20 minutes (S1200). It is most efficient and desirable for the first wet bibeam to run for 15 minutes and can increase or decrease in proportion to the dose of fiber fed.

40 wt% (%) of the water prepared in the first wet bibim-finished composition is added (mixed and subjected to the second wet bibim treatment for any one time selected from the range of 20 to 30 minutes (S1300). It is most efficient and desirable to proceed with minutes and can increase or decrease in proportion to the dose of fiber fed.

40 weight percent (%) of water prepared in the second wet bibim-finished composition is added (mixed and subjected to a third wet bibim treatment for any one time selected from a range of 30 to 40 minutes (S1400). It is most efficient and desirable to proceed with minutes and can increase or decrease in proportion to the dose of fiber fed.

In another embodiment, when the silica fume composition is not added or mixed in the dry bibim step, the prepared silica fume is added or mixed to process the third wet bibim.

Since the viscosity may be increased when the silica fume is added, it is preferable to increase the time of the third wet bibeam by about 1 to 2 minutes.

The third wet bibim-finished material is added to a prepared mold or construction site and maintained at a room temperature (room temperature, 25 degrees Celsius) (S1500).

It is preferable that at least 30 minutes of the third wet bibimb be completed and put into the mold or maintained at a fixed state of the material put into the construction site for aging.

If the time is put into the mold and aged in a fixed state without moving at all is less than 30 minutes, the foam tissue is broken or the wind is blown, the size of the foam tissue is reduced, if more than 30 minutes when the aging is completed in subsequent work It may cause a disruption and lower productivity.

After entering the mold, check whether the total 4 hours have elapsed at room temperature including the ripening time (S1600), and if the total 4 hours including the initial ripening time 30 minutes has elapsed at room temperature, remove or separate the frame to prepare a foamed foam foam. Complete the step (S1700).

The lightweight cement foam produced in the same manner as shown is shown in Figure 2 attached.

The lightweight foam cement foam made of the lightweight foam cement composition having the above-described configuration has a number of foam structures per unit area having a uniform size, and thus has excellent soundproofing, heat insulation, and moisture proofing effects, and is light in weight and has adequate strength. It is used as a building material by maintaining it, and is suitable for blocking noise between floors and maintaining pleasant living space.

In addition, there is an advantage that the life is relatively long because it does not emit toxic gases even at high temperatures in the surrounding environment, and environmentally friendly and excellent bonding force between the foam structure.

In addition, since the manufacturing at room temperature has the advantage of reducing the equipment cost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
