Description

[0001] The present invention relates to a ball type deodorization and air freshener used diatomite,

The present invention relates to a ball-type deodorant comprising diatomaceous earth as a main component and an eco-friendly material having a cured structure that does not use a chemical adhesive.

In recent years, there has been much interest in indoor deodorant, and improvement of the indoor environment of the living space has been made by revising and revising laws and regulations. However, deodorants, which are made of chemical-based materials, are still being used extensively. There is a problem that the use of an adhesive releasing a volatile organic compound is large and the flame retardant performance is poor. In addition, since it is often exposed to chemical products in a closed indoor structure, health problems and environmental pollution are continuing. There are many cases where a pleasant living environment can not be maintained.

In response to this social interest, the present invention was developed for the purpose of producing natural deodorant.

In order to solve the above conventional art, porous diatomaceous earth is used as a main material, and a molding material is bonded using a flour paste as an adhesive without using a chemical adhesive as a binder. The present invention provides a molded article of a diatomaceous earth deodorant contributing to the improvement of the indoor environment by having an eco-friendly binding material as a main curing structure and being formed of an eco-friendly material and having a deodorizing and humidity control function.

In order to achieve the above object, the technical method of the present invention is a deodorant comprising 60% of diatomaceous earth, 10% of gypsum powder, 15% of white cement, 10% of general flour paste, and 5% of powdered resin.

The molded product produced by the present invention is mainly made of diatomaceous earth and contributes to deodorization. Since all the additives are eco-friendly, there is no harmful substance to the human body and no obstacle to environmental pollution.

Diatomaceous earth, which is a main component of the present invention, has been widely known and has been industrially useful. These diatomaceous earths are lightweight natural minerals composed of micropores with more than 80% of SiO ₂ , which is formed by the deposition of monocellular organisms of phytoplankton, monosized organisms. This diatomaceous earth is used industrially as a filter aid, insulation, and absorbent, and it is used for building use of absorption, decomposition and deodorization of noxious gas, and as a material of fireproof, lightweight and eco-friendly building material.

Generally, diatomaceous earth is produced by mining, screening and grinding, followed by sintering process to remove water and impurities, and processing to a suitable particle size for application. The diatomite powder thus processed has different physical properties depending on the place of production or use. In order to exhibit optimal performance, the diatomaceous earth suitable for the present invention is preferably a diatomaceous earth having an absorption rate of 180 to 250 and an average particle size of 50 to 80 탆. When the water absorption rate is low, the basic property of the diatomaceous earth is small and the activity thereof is lowered. Similarly, even if the particle size is too small, the pores disappear due to the pulverization, making it difficult to sufficiently exhibit the performance suitable for the present invention. The diatomaceous earth having an average particle diameter of 10 to 100 mu m can be used, more preferably 50 to 80 mu m, because it has a high specific surface area and a high water absorption rate, and is excellent in adsorption / decomposition, deodorization and humidity control of noxious gas.

The composition of the diatomite is preferably 50 to 65% by weight. It is obvious that the smaller the amount of diatomaceous earth used, the lower the performance required in the present invention. On the other hand, when the composition is at least 65% by weight, adhesion with the adherend, strength, and workability are deteriorated, making it difficult to continuously maintain durability as a room deodorant.

In the present invention, it is preferable to use 60% of diatomaceous earth, 10% of gypsum powder, 15% of white cement, 10% of general flour paste and 5% of powdered resin as a composition for forming a cured structure.

The present invention is applied to the present invention as a low carbon, eco-friendly material. In addition, to ensure initial hardening and to prevent cracking, it is molded into an integral system and an automatic ventilation system
