Description

A pillar of the manufacturing methods and protective finishes Vermiculite}

The present invention relates to a pillar-protecting vermiculite finish and a method of manufacturing the same, which is formed in a round pipe shape to protect the 'vermiculite' which expands in volume when heating a gemstone and has vermiculite having non-combustibility, heat insulation, heat resistance and light weight. .

More specifically, the existing vermiculite board, which has a panel shape by compressing and molding the vermiculite which expands upon heating, is adhered to the melamine sheet, cut into a certain thickness, and formed into a round pipe shape to wrap the outside of the column in ships and finish. Insulation, as well as the generation of harmful gases in the event of fire to protect the pillars.

In general, the type of heat insulating material can be classified according to the type or shape of the material or the temperature used, and generally can be classified into inorganic materials, organic materials and composite materials.

Inorganic materials include rock wool, glass wool, vermiculite and perlite, and organic materials include polystyrene cork and polyurethane urea.

In addition, rock wool or glass wool, which is used most among inorganic materials, is reluctant to use it because it is a carcinogenic substance or because there are many harmful elements to human body due to the fine powder scattered during handling. .

On the other hand, organic insulating materials are frequently used because of their ease of handling and relatively good thermal insulation. However, they are vulnerable to heat and generate toxic gases due to ignition. In the end, they are all ignited at high temperatures to generate toxic gases, which is why they are reluctant to use these toxic gases at the fire site due to social problems.

Therefore, in the future, it was required to develop a heat insulator that does not cause environmental problems unless the heat insulators used for buildings or industrial use are not burned and generate soot or toxic gas.

Therefore, expanded vermiculite was developed in response to these demands, and vermiculite is composed of SiO₂ (37.3%), Al₂O₃ (11%), K₂O (4.88%), Fe₂O₃ (4.52%), and M (27.6%). ), lg (10.8%), CaO (1.08%), etc., which is good for human body, it has high spectral distribution of far infrared rays, so it has high far-infrared radiation, excellent deodorizing and antibacterial properties, and excellent fire resistance. It is used for wall, and used as prevention of heat after radiating board of electronic products, and especially powder is used as gypsum board and fire retardant paint, coating agent and filler by grinding various kinds of particle size.
