이하에서는 도면 및 실시예를 참조하여 본 발명에 따른 건축용 세라믹 성형체를 보다 상세하게 설명하기로 한다.Hereinafter, with reference to the drawings and the embodiment will be described in more detail the building ceramic molded body according to the present invention.
도 1은 본 발명의 일실시예에 따른 건축용 세라믹 성형체의 제조 과정을 도시한 흐름도이다.1 is a flowchart illustrating a manufacturing process of a ceramic ceramic molded body according to an embodiment of the present invention.
본 발명의 일실시예에 따른 건축용 세라믹 성형체는 황토가 코팅된 펄라이트 입자 및 질석 입자를 입자 결합용 바인더와 혼합하여 성형시킨 것을 특징으로 한 다.Building ceramic molded body according to an embodiment of the present invention is characterized in that the molded clay is mixed with a pearlite-coated pearlite particles and vermiculite particles combined with a binder for particle bonding.
황토가 코팅된 펄라이트 입자는 펄라이트 입자는 표면에 황토가 물에 분산된 코팅용액을 코팅, 건조시켜 형성된다. 본 발명에서 '펄라이트 입자'란 발포된 상태의 펄라이트 입자를 의미한다. 코팅용액은 황토분말 20~40중량%, 물 50~70중량%, 코팅용 바인더 5~10중량%(바람직하게는 황토분말 25중량%, 물 70중량%, 코팅용 바인더 5중량%)를 혼합하여 제조된다. 상기 코팅용 바인더(점결제)는 황토 분말 입자가 펄라이트 입자의 표면에 잘 부착되도록 하기 위한 것으로, 당밀이나 전분과 같은 천연물질이 사용되는 것이 바람직하다. 황토의 코팅은 펄라이트 입자를 코팅용액에 담가 이루어질 수 있으나, 바람직하게는 펄라이트 입자 알갱이를 굴리면서 그 위로 코팅용액을 분사시켜 이루어지는 황토 코팅막을 균일하게 형성할 수 있다.The ocher coated pearlite particles are formed by coating and drying the coating solution in which ocher is dispersed in water. In the present invention, the term "perlite particles" refers to perlite particles in a foamed state. The coating solution is mixed 20 to 40% by weight of ocher powder, 50 to 70% by weight of water, 5 to 10% by weight of coating binder (preferably 25% by weight of ocher powder, 70% by weight of water, 5% by weight of coating binder). It is manufactured by. The coating binder (binder) is to make the ocher powder particles adhere well to the surface of the pearlite particles, and natural materials such as molasses or starch are preferably used. The coating of ocher may be made by immersing the pearlite particles in the coating solution, but preferably, the ocher coating film formed by rolling the pearlite particles and spraying the coating solution thereon may be uniformly formed.
상기와 같이 황토 코팅용액이 펄라이트 입자에 코팅된 후 건조된다. 건조는 실온에서 음건시키거나 건조시간의 단축을 위해서 40~50℃의 온풍으로 건조시킬 수 있다. As described above, the ocher coating solution is coated on the pearlite particles and then dried. Drying can be dried at room temperature or by a warm air of 40-50 ° C. to shorten the drying time.
한편, 성형체로부터 향기가 발산되도록 펄라이트 입자에 피톤치드와 같은 향료를 흡착시킬 수 있는데, 향료의 흡착은 황토를 펄라이트 입자에 코팅하기 전에 이루어진다. 즉, 상기 펄라이트 입자를 향료용액에 침지시키거나 향료용액을 펄라이트 입자에 분사시킨 다음 그 펄라이트 입자 표면에 황토를 코팅, 건조시킨다. 상기와 같이 향료가 흡착된 펄라이트 입자로부터는 향기가 발산되는데, 그 펄라이트 입자의 표면에 황토가 코팅되어 향기의 발산 속도가 늦어져 향기의 발산기간이 길어지게 된다.On the other hand, the fragrance such as phytoncide can be adsorbed to the pearlite particles so that the fragrance is emitted from the molded body, the adsorption of the fragrance is carried out before coating the loess to the pearlite particles. That is, the pearlite particles are immersed in the perfume solution or the perfume solution is sprayed on the pearlite particles, and then the ocher is coated on the surface of the pearlite particles and dried. As described above, the fragrance is adsorbed from the pearlite particles adsorbed, the ocher is coated on the surface of the pearlite particles, so that the fragrance of the fragrance is slowed down, so that the fragrance of the fragrance is extended.
상기와 같이 황토가 코팅된 펄라이트 입자와 질석 입자가 혼합된 배합물에 입자 결합용 바인더와 혼합되어 판넬이나 블록과 같은 형태의 성형체로 성형된다. 즉, 황토가 코팅된 펄라이트 입자 60~85중량%, 질석 입자 5~20중량%, 입자 결합용 바인더 5~25중량%(바람직하게는 황토가 코팅된 펄라이트 입자 70중량%, 질석 입자 7중량%, 입자 결합용 바인더 23중량%)를 혼합하여 건축용 판넬과 같은 건축용 자재로 성형된다. 본 발명에서 '질석 입자'란 발포된 상태의 질석 입자를 의미한다. 상기 입자 결합용 바인더(점결제)로는 당밀 또는 전분 용액과 같은 천연 재료가 사용되는 것이 바람직하다.The clay-coated pearlite particles and vermiculite particles are mixed with the binder for particle binding to form a molded article such as a panel or a block. That is, 60 to 85% by weight ocher coated pearlite particles, 5 to 20% by weight vermiculite particles, 5 to 25% by weight binder binding particles (preferably 70% by weight ocher coated pearlite particles, 7% by weight vermiculite particles) 23% by weight of a binder for particle bonding) is mixed into a building material such as a building panel. In the present invention, the vermiculite particles mean vermiculite particles in a foamed state. It is preferable that a natural material such as molasses or starch solution is used as the binder for binder binding.
