Description

Production Method of Rock Wool Panel and Production System of The Same

The present invention relates to a method and a manufacturing system of a rock wool panel capable of continuously producing a rock wool panel excellent in strength because the internal binder is easily and quickly cured and dried by resistance heating or induction heating.

As a prefabricated building material for thermal insulation, E.P.S. Sandwich panels and urethane panels are known, and glass wool panels and concrete PC panels are known as non-combustible panels.

However, the panel made of the above-mentioned foamed synthetic resin is vulnerable to fire and generates a large amount of toxic gas during combustion, and since the glass wool panel is dependent on manual work in manufacturing, the manufacturing process is complicated and the insulation board structure is horizontally layered. It is easy to crack due to weak tensile strength on the horizontal surface and weak to external pressure, and the concrete PC panel has heavy product and low impact strength, which makes it difficult to transport and construct and is expensive.

In addition, ceramic fiber panels, known as non-combustible panels, are impregnated with a liquid binder in a wet process to remove the liquid by vacuum, and then dried, and then commercialized after surface treatment. Therefore, a long time is required to dry the inside of the panel. The surface hardness is very low, the flexural strength is small, easily broken and a large amount of ceramic fiber is discarded during the cutting and surface treatment process of the product.

As a non-combustible panel of the related art, a rock wool panel manufactured by a method similar to the glass wool panel described above is known.

The rockwool panel uses a water-soluble phenolic resin, an acrylic emulsion, and the like as a binder, and evaporates moisture using a drying apparatus such as high frequency, far infrared rays, and hot air to dry and cure the binder.

The conventional rockwool panel manufacturing method as described above is complicated by the manufacturing process, and the production cost increases because it takes a lot of time and cost to evaporate, dry and cure the moisture of the binder.

In case of high frequency drying, it is difficult to control temperature, carbonization of binder occurs due to high heat generation inside, replacement by frequent failure of magnetron device that generates expensive high frequency, harmfulness to human body and high price when high frequency external leakage occurs. There is a problem such as installation cost.

In the case of far-infrared drying, surface carbonization of the panel occurs due to the high temperature of the surface of the heating element. Therefore, the distance and temperature control between the heating element and the panel must be properly maintained.

In the case of hot air drying, the rock wool, which is the main material, has excellent thermal insulation properties, making it difficult to penetrate the temperature into the panel, and it takes a long time to cure the binder inside the panel.

However, non-combustible panels that are excellent in light weight, flame retardancy, sound absorption, and heat insulation are required for certain standard buildings, such as apartments, houses, factory buildings, prefabricated mall buildings, and high-rise buildings. Complexity, difficulty in continuous production, and costly production are exposed.

An object of the present invention is to solve the above problems, to maintain the light weight, maintain the granular state of the compact structure and the automated dry production process of the thermal curing speed of the binder is very fast mass production possible and non-combustible The present invention provides a method and a manufacturing system for rock wool panels, which have no toxic gas emission, have excellent flame retardancy, excellent incombustibility, and high strength.
