It is an object of the invention to provide a soundproof construction composition using waterworks sludge that increases beneficial effects such as soundproof, moistureproof, heat protection and no environmental pollution by solving the problems of a soundproofing material for a polymer completely, and a method for preparing the same, as an improvement of Korean Patent No. 10-622394 (Application No. 10-2004-56950) and Korean Patent No. 10-663235 (Application No. 10-2004-56949) entitled "A method of preparing a construction material using waterworks sludge” and "A composition of construction material using waterworks sludge and a method of preparing the same," respectively.
- Technical Solution
- the product manufactured like this has characteristics that it is easy to dry it, its resistance against quick heating or cooling is strong, it is lightweight and its soundproof effect is superior, and it causes no environmental pollution and its adiabatic effect is increased due to its high heat resistance compared to prior art soundproofing material having low adiabatic property and environmental pollution problem.
- the product according to the present invention can increase beneficial effects such as soundproof, moistureproof, heat protection, no environmental pollution by solving the problems of the prior art soundproof material completely by:
- a porous body is chemically foamed by generating hydrogen gas through reaction of aluminum powder with an acid or an alkali after slipping the body.
- the porous body can express the feel of surface naturally by pores contained in everywhere of the surface, the material of a pouring mold can be employed in organic material such as vinyl, and the porous body is effective in manufacturing large soundproof product since it is dried easily, has strong resistance against quick heating or cooling, and the weight of a product made therefrom is lightweight.
- a soundproof construction composition using waterworks sludge having a total contraction rate of 8-10% and an apparent porosity of 50-52%, which is manufactured by mixing 22% by weight of a first processed clean water sludge made by firing waterworks sludge for 3-5 hours at 800°C-850°C, with 18% by weight of clay, 36% by weight of terra alba, 14% by weight of agalmatolite, and 10% by weight of dolomite to obtain a body, mixing 31.5% by weight of the body with 2.3% by weight of calcined gypsum, 11.3% by weight of cement, 0.05% by weight of aluminum powder, 0.5% by weight of starch, 0.5% by weight of titanium dioxide to prepare a powdery mixture, and mixing the powdery mixture with 10.8% by weight of phosphoric acid and 43.05% by weight of water, stirring the resultant mixture, and firing it at 1100 0 C in heating furnace, and
- the body according to the present invention was chinaware body fired at 1100 0 C, phosphoric acid fluid was used in acid reaction foaming and sodium hydroxide was used in alkali reaction foaming as a foaming promoter. Further, a dispersant and a foam stabilizer were used as other aids.
- the concentration of the body slip suitable for foaming is decided, the effect of the calcined gypsum and cement on setting-hardening reaction of the slip and the combination rate are elicited, and its handling strength and firing property were examined.
- the present inventors observed forming possibility and drying and firing state, and investigated the compatibility with glaze when using rag or Styrofoam rather than gypsum as a mold in setting-hardening reaction of porous body with manu- facturing a trial product.
- aluminum powder reacts with an acid or an alkali, hydrogen gas is generated, thereby forming foam and forming many pores within the body. Therefore, three points of component, fineness and particle type are uniform, non-oxidized state is important, and large specific surface area is preferable, i.e., the fineness is less than 50 micros.
- a foam promoter such as sodium hydroxide, a surfactant and a foam stabilizer are preferably used in combination with aluminum powder.
- Such other aids are described below.
- a foaming agent disperses each component in the slip.
- a surfactant such as an organic acid, e.g., lignin-sulfonate, and a polymer counteragent is used, but the dispersant may not be used in the present invention.
- a foam stabilizer stabilizes foam within slip, prevents foam from aggregating and distributes uniformly. Saponin, protective colloid or starch, etc. were used as such a foam stabilizer.
- a hardening accelerator is a dilute slip containing much water in body raw material, and thus has strength through setting-hardening reaction of cement rather than drying. At this time, calcium oxide, its salt and water glass, etc. were used for shortening the setting time.
- a first process processing of a first processed clean water sludge
- the basic body used in this experiment was a chinaware body fired at 1100 0 C using the first processed waterworks sludge, and its combination rate was as follows.
- the particle size of the body was such that residual amount is less than 1% when the body was passed through a 200-mesh sieve.
- Aluminum powder used as a foaming agent is a product available at H-non-iron powder company and is employed in paints, etc.
- Dish cleaner which is a surfactant was used as a dispersant
- starch was used as a foam stabilizer
- calcined gypsum was the second grade product of M-chemistry
- general Portland cement was used as a cement
- sodium hydroxide and phosphoric acid aqueous solution were commercially available industrial products.
- a body was dried and pulverized, and then passed through a 20-mesh sieve. The resultant body in powdery state was used. Calcined gypsum and cement were also sieved through 20-mesh sieve, and ultimately their powder in no mass state was used.
- the raw material used in the experiment is categorized into solid in powder state and liquid such as water or phosphoric acid. Combining the raw material was performed in principle by first mixing solid with solid and mixing liquid with liquid, and then putting solid sample in liquid sample. The soluble material such as sodium hydroxide was first dissolved in water.
- Aluminum powder which is a foaming agent, was dispersed in water in a state well mixed with a surfactant.
- the weight of the test piece was such that the total amounts of the three raw materials, i.e., a body, calcined gypsum and cement are 50g.
- Other aids such as a foaming promoter were additives.
- Foaming temperature and drying [59] The foaming reaction of the sample was well performed at ambient temperature in acid foaming, and at 60-80 0 C for promoting foaming in alkali foaming. The apparatus at this time was constant temperature dryer.
- test pieces were taken out and naturally dried when some were dried with setting-hardening in a state being separable from a container such as a beaker.
- a porous body is chemically foamed by generating hydrogen gas through reaction of aluminum powder with an acid or an alkali after slipping the body.
- the porous body can express the feel of surface naturally by pores contained in everywhere of the surface, the material of a pouring mold can be employed in organic material such as vinyl, and the porous body is effective in manufacturing large soundproof product since it is dried easily, has strong resistance against quick heating or cooling, and the weight of a product made therefrom is lightweight.
- this experiment forms many pores on the body by acid reaction and alkali reaction.
- the range of selecting the pouring mold is widen, the foaming reaction is well achieved at ambient temperature, and the acid reaction foaming is good so that the feel of surface may be natural since pores having various sizes are contained in everywhere of the surface, wherein the combining rate by weight is as follows:
- the fired porous soundproof material has about 8-10% of total contraction rate and about an apparent porosity of 50-52%.
- a porous body according to the present invention is chemically foamed by generating hydrogen gas through reaction of aluminum powder with an acid or an alkali after slipping the body.
