Description

The utility model relates to the field of construction, in particular, to the production of cladding panels used in the installation of ventilated facades for exterior and interior decoration of buildings and premises, both new and old, to improve the appearance and insulation.
The following requirements are imposed on the facing panels used in construction: high strength, lightness, fire resistance.
To date, the most popular and widely used are various designs of aluminum composite panels, protected by patents (RU No. 47931, U1 E04F 13/08 Е04В 1/80, 09/10/2005; RU 83527, U1 E04F 13/077, 10/10/2009 At the same time, these panels, containing aluminum sheets located on the outside, are expensive and do not fully satisfy such a parameter as fire resistance.
Known multilayer panel consisting of a wooden frame, non-structural insulation and sheet sheathing, which can be used galvanized metal sheets. (RU # 90820, U1 E04C 2/00, 01/20/2010)
The disadvantage of this design is the complexity of its manufacture, since it is assumed to use manual labor in the manufacture of a wooden frame, the insufficient fire resistance of the panel due to the use of a wooden frame.
Also known is a multilayer panel with an insert made of whole or consisting of sound absorbing elements, basalt mineral wool, and the sound absorbing element is lined with acoustically transparent material, for example fiberglass, and the front and rear walls of the frame are made of stainless steel or galvanized 0.7 mm thick sheet or aluminum sheet. Moreover, one of the walls of the frame is perforated. (RU No. 2362855, U1 ЕВВ 1/82, 07/27/2009).
This panel is designed for sound absorption and does not have a sufficient degree of fire resistance.
Closest to the claimed solution is a panel of the "sandwich" type with a combined heater, in the form of a mineral wool board, treated with a one-component adhesive on the surface, and laying on the adhesive a polystyrene plate coated on both sides with galvanized metal. (RU 2346119 С2, Е04С 2/292, В32В 5/22, В32В 7/12, В30В 5/06, published on 02/10/2009)
The disadvantage of this panel is the need to carry out a number of additional operations during their production, which make it possible to obtain a sandwich panel with a combined heater. In addition, the known panel does not have a sufficient degree of fire resistance, since fire resistance functions are assigned to a layer of mineral wool, the second inner layer of expanded polystyrene, like many thermoplastics, relates to combustible materials and despite the fact that fire risk significantly reduces the fact of application expanded polystyrene as a middle layer, fire resistance of these panels is low.
The objective of this utility model is to create a panel with high fire resistance.
The present problem is solved in that in a multilayer panel including an inner layer and facing sheets of galvanized metal, according to the claimed utility model, the inner layer is a core made of a composite material consisting of a non-toxic flame-retardant mineral filler and a binder polymer, and representing a homogeneous phase based on a polyethylene composition filled with hollow microspheres filled with flame retardant and pentaerythritol, coated on both sides with a thermo layer polymer adhesive, the core is lined with galvanized steel sheets, while on the outside of the plate the galvanized steel sheet is coated with a primer layer PVDF or PE, enamel layer PVDF or PE, the back side of the panel is protected by a corrosion-resistant coating.
The core can be made in the following ratio of the components of the composition: flame retardant mineral filler - 70-85 wt.%, A binder polymer - 25-10 wt.%, And thermopolymer adhesive - 5 wt.%, In the following.
The outer surface of the panel may be protected by a polymer film.
Ammonium polyphosphate can be used as a flame retardant.
The implementation of the core of the panel in the form of a homogeneous phase from a composite material containing non-toxic flame-retardant mineral filler and a binder polymer, as well as the lining of galvanized steel panels, allows for a high degree of fire resistance of the panels and fire safety of the products made of them.
Figure 1 shows a fragment of the structure of a fire-resistant composite steel panel; figure 2 - the core of the fire-resistant composite steel panel
The fire-resistant composite steel panel is multilayer and has the following structure: core 1, consisting of a composite material and a binder polymer, coated on both sides with a layer of thermopolymer adhesive 2, galvanized steel sheets facing 3, on the outside of the panel - primer layer 4, enamel layer 5 , a protective film 6, from the back of the panel anti-corrosion coating 7.
Fire-resistant composite steel panels are produced on a special high-tech line of the KRASPAN plant, which includes an extruder capable of producing composite panels with a core containing up to 85% of the mineral filler.
The technology for producing composite material is “know-how” and is used for the production of panels of the “Kraspan” trademark. A core consisting of a composite material and a binder polymer, coated on both sides with a layer of thermopolymer adhesive, is obtained by co-extrusion through a flat slot head, in the form of a sheet up to 6 mm thick, coated on both sides with thermopolymer adhesive, and is fed to the lining.
The high content of the mineral component in the inventive fire-resistant composite steel panel leads to an increase in strength, fire resistance and durability of the material.
Due to the combination of fire resistance, strength and ductility, panels are used not only in facade construction, but also for interior decoration.
