Description
FIRE-RESISTANT, LOAD BEARING AND INSULATING MATERIAL OF SANDWICH PANEL WITH A CORE BASED ON MAGNESIUM OXYCHLORIDE OR OXYSULFATE BINDER
DESCRIPTION
The subject matter of the invention is fire-resistant, load bearing and insulating material used mainly as load bearing reinforcement of sandwich panel core or as a sandwich panel core making the panels highly durable, featuring high compression strength parameters as well as the manufacturing method of the material.
Sheathing board of sandwich panels which comprises of fibreglass mesh and glass, aramid carbon and polycarbonate fibres reinforcement which includes compositions of silicon, carbonates and sodium carbonate as binding material with the insulation material of the core such as polystyrene, polyurethane foam or mineral wool is already widely known.
The subject of the invention is presented in the Figure 1A which shows views of sandwich panel with high fire-resistance, low heat conductivity and high tensile strength core. Figure 1B pictures a cross-section of the sandwich panel in question where longitudinal beams reinforcing the sandwich panel made of the revealed material are filled with insulation core. It is possible to use multiple layers of the boards with the revealed filling material only - Figure 1 A, or with internal framing or rigging made of the filling material being revealed - Figure 1 B.
The material being reserved as the invention is made by a shaped prefabricate of the material mass (1) see fig 1 , which contains the following in weight ratio:
40% of magnesium oxide,
40% of perlite and hydrophobic perlite grain size from 0,01mm to 2mm,
30% of magnesium chloride,
30% magnesium sulphur,
30% chippings of extruded polystyrene grain size from 0,1mm to 2mm,
20% volatile ash and pozzolan,
20% furnace ash
20% sludge and waste dust and filtration wastes,
20% light-weight 'bloated' clay aggregate and hydrophobic light-weight clay aggregate grain size from 0,1 mm to 3mm,
20% coal from adsorbed carbon dioxide,
10% carbon fibres in the form of reinforcement of the length of 1mm to 40mm,
10% polyester fibres in the form of reinforcement of the length of 1mm to 40mm,
10% aramid and polycarbonate fibres in the form of reinforcement of the length of 1mm to 40mm,
10% basalt and polycarbonate fibres in the form of reinforcement of the length of 1mm to 40mm,
10% silicon and up to 10% sodium carbonate,
5% fibreglass mesh in the form of reinforcement of the length from 1 mm to 40mm,
3 % copper carbonate,
3 % toluene,
3% carbon black,
3% iron oxide and pigments.
The necessary chemical bindings in the mass, to which the rights are being reserved, are obtained twofold. Each method of obtaining the material is divided into three phases of mixing where:
in the first phase, a dry phase, magnesium oxide, perlite, hydrophobic perlite, volatile ash, puzzolan, various grain sizes of furnace ash, fibres of reinforcement, silicon and sodium carbonate, light-weight 'bloated' clay aggregate and hydrophobic light-weight clay aggregate are mixed in mixer at the speed up to 50 revolutions pre minute and temperature up to 30 degrees Celsius for not longer than 15 min,
in the second phase, a wet phase, consisting in mixing a saturated solution of magnesium chloride blended with waste sludge and filtration wastes as well as magnesium sulphur until the mixture is homogeneous and the granules of the wastes are completely dissolved and than the blend is enhanced with pigments, copper carbonate, toluene, carbon black and iron oxide in order to acquire primary bindings of compounds of magnesium carbonate and distribute pigment to get even colour of the mass in the temperature up to 80 degrees Celsius.
The third phase consists in joining both masses created in the previous two phases where the blending is processed until homogeneous consistence and colour of mixture is constituted and than the mass is formed in moulds or it is poured directly between external sheathing boards of the panels so the panels core is created or it is poured into the cavities in the sandwich panels so the internal load bearing rigging or reinforcing framing is made. This method eliminates the use of glues which are not resistant to high temperatures. The poured mass is of consistence of semi dry or dry concrete. After the moulds, boards or cavities in panels are filled, the mass is left to stay and mature for few hours depending on its consistence. The other method for obtaining the bindings holding the mass together, apart from blending, is foaming the mass by means of pressurised carbon dioxide or carbon dioxide and compounds of sulphur and other
volatile ash, puzzolan, included in the exhaust gasses of combustion process of fossil fuels ex.: coal fired power plants. The mass comprising of mixture of liquid (by spraying the mixture into the chamber filled with exhaust gasses or into a scrubber) or half liquid (by force pumping the pressurised exhaust gasses into the half liquid solution) magnesium oxide and saturated magnesium chloride is exposed to the exhaust gases absorbing volatile substances creating silicon bindings with the volatile ash, desulphurises the fumes binding magnesium sulphur and absorbs carbon dioxide by fixing it to magnesium carbonate compounds. Such saturated and primarily enhanced mixture is subject to adding the remaining ingredients including perlite, hydrophobic perlite, furnace ash, fibres of carbon, glass or plastic reinforcement, light-weight 'bloated' clay aggregate and hydrophobic light-weight clay aggregate, pigments, copper carbonate, toluene, carbon black, iron oxide until required colour or properties are obtained. The final process of mixing is conducted at the temperature up to 80 degrees Celsius and at no more than 50 revolutions per minute.
This version of the board includes the majority of polystyrene or perlite granules joined by strong binding of magnesium carbonate and magnesium chloride and in its mass is reinforced with silicon structure.
The advantage of the solution of core or load bearing rigging or framing described above made of material being reserved is the possibility of application of such enhanced sandwich panel as main load bearing building prefabricate which consist of two or more external sheathing boards with the core made of organic (hey, clay, sawdust), plastic (polystyrene, polyurethane, polyvinyl) or rock wool, foam, textile and oil derived material.
The sandwich panels of the invention with the internal rigging or framing made of the material being reserved are particularly resistant to compression, strain and fire maintaining thermal insulation properties. Such panels are non toxic and cheap in manufacturing.
