Description
An ecological composite for manufacturing thermoinsulating panels for the building industry
The subject of the invention is an ecological composite for manufacturing thermoinsulating panels for the building industry, which are used to make internal insulation of brickwork and load-bearing walls of buildings, especially in places where a high level of microclimate hygiene in residential buildings is required.
A thermoinsulating material is known from patent application SK 428-2003, which is designed for the insulation of external building structures from their internal side, based on cement, calcium hydroxide, perlite and cellulose fibres, along with the method of its production and manufacturing of panels. The material consists of: 10.5 to 16.5% by weight of cement, 52.5 to 60% by weight of calcium hydroxide, 16.5 to 26.5% by weight of perlite and 1.5 to 10.5% by weight of cellulose fibres.
Also known from patent application BG105813A are
thermoinsulating building material used as thermoinsulating plaster to be laid on concrete, brick or stone wall, and for the manufacturing of prefabricated panels or blocks. The material is based on perlite and cement, with burnt lime as a binder, and contains 57 to 60% by weight of perlite, 37 to 40% by weight of cement, 2 to 3% by weight of polymer and 0.2 to 0.3% of cellulose.
A thermoinsulating building material is known from patent application BG104756A and contains 62 to 68% by weight of perlite,
30 to 35% by weight of cement, 2 to 3% by weight of polymer and 0.2 to 0.3% of cellulose.
Patent application JP4130038A shows a building material produced of inorganic wastes with an additive of spongy perlite forced into the cellulose fibres. The material contains e.g. 48% cement, 43% siliceous sand, 10% by weight of clay, 5% by weight of cellulose fibres, 1% by weight of spongy perlite and 30% by weight of water.
Also known from patent specification PL 199618 Bl is a method of manufacturing a thermoinsulating plaster mix used for the insulation of new buildings and the renovation of historic facades. The method involves efficient mixing in order to produce foam - 20.5 to 26.5 parts by weight of CEM I 42.5 R cement, 8.8 to 14.8 parts by weight of hydrated lime in loose form, 43.8 to 49.8 parts by weight of dried quartz sand with granularity of 0.0 to 0.075 mm, 11.7 to 17.7 parts by weight of EP 150 expanded perlite with an average bulk density of 150.0 g/cm3, up to 5.9 parts by weight of vinyl copolymer in loose form, up to 4.9 parts by weight of thickening and fluffing additives.
According to the invention, the ecological composite for
manufacturing thermoinsulating panels for the building industry is characterised in that it contains 50 to 70% by weight of cellulose and 20 to 40% by weight of expanded perlite, with respect to dry matter.
Preferably, the composite consists of 60 to70 % by weight of cellulose and 30 to 40% by weight of expanded perlite, with respect to dry matter. Preferably, the composite consists of 60% by weight of cellulose and 40% by weight of expanded perlite, with respect to dry matter.
For the purposes of composite manufacturing according to the invention, industrial cellulose is acquired from waste paper, newspaper and cardboard packaging. Panels made of the composite according to
the invention are used to replace polystyrene foam and/or mineral wool insulation wherever there is no possibility to make external insulation, e.g. on facades of buildings falling within conservation regulations. The thermal conductivity coefficient for cellulose fibres ranges from up 0.036 to 0.042 W/(m-K), and thus it is comparable with the thermal conductivity coefficient for mineral wool or polystyrene foam. Panels made of the composite fit perfectly into the ecological building trend.
Example embodiments of the invention
According to an example embodiment of the invention, raw material (waste paper, newspaper and cardboard packaging) in the amount of 60% by weight, containing cellulose, is soaked in tubs containing water at an ambient temperature. Powdered expanded perlite in the amount of 40% by weight (with respect to dry matter) is added to the water cellulose pulp. After mixing, the panel moulds are filled with the composite and placed within a mechanical press moulding, preferably under a hydraulic press, until the specified density is obtained. This is followed by forced drying in drying chambers to reach a humidity level of 8% up to 15%. Ready panel contains 60% by weight of cellulose and 40% by weight of perlite. A 60 mm-thick insulation layer guarantees an overall heat-transfer coefficient (U) from 0.040 to 0.055 W/(m2-K).
In another example embodiment of the invention, raw material (waste paper, newspaper and cardboard packaging) in the amount of 70% by weight, containing cellulose, is soaked in tubs containing water at an ambient temperature. Powdered expanded perlite in the amount of 30% by weight (with respect to dry matter) is added to the water cellulose pulp. After mixing, the panel moulds are filled with the composite and placed within a mechanical press moulding, preferably under a hydraulic
press, until the specified density is obtained. This is followed by forced drying in drying chambers to reach a humidity level of 8% up to 15%. Ready panel contains 70% by weight of cellulose and 30%> by weight of perlite. A 60 mm-thick insulation layer guarantees an overall heat-transfer coefficient (U) from 0.040 to 0.055 W/(m2-K).
