Description

DESCRIPTION
PRODUCTION METHOD OF THE HEAT AND SOUND INSULATION PROVIDING PROFILE CREATED IN MONOLITHIC STRUCTURE USING STRENGTH
INCREASING MATERIAL
Related Art
The invention relates to profiles used in window and door systems.
The invention relates to, in particular, production method of profiles, providing high heat and sound insulation, wherein different materials are fused in the empty inner section, PVC material is found on the upper surface, filling material and/or strength material in the inner part, obtained in monolithic structure by means of concurrent inclusion of these materials in the production.
Prior Art
Today, often polyvinyl chloride (PVC) materials are used in window and door systems because of superior properties of theirs such as high durability, easy cleaning, and insulation. Auxiliary elements named as support sheets are used inside of the PVC profiles to enhance the durability. Said support sheet is produced separately from the main profile and then window or door systems are created by means of then placing it into the profile.
Manufacture of the support sheets positioned inside of the PVC profiles to enhance the strength from metal material leads to corrosion, causing increase in the weight of the profile and in the cost of the labour. However, it brings along many disadvantages such as purchase of additional machinery and equipments.
On the other hand, support sheet manufactured from metal materials needs to be cut short to achieve placement of its in location inside of the profile. Therefore, that support sheet is left unattended without connecting them on the corners. Failure to carry out the process of jointing on the corners and the support sheet remaining fragmented inside of the profile cause significant loss of strength on the corners. Therefore, corner parts of the profile are susceptible position to the impacts and damages from outside.
At the same time, support sheets placed into the profiles cause to heat losses because they provide heat conductivity easily. Given the most important reason for installation of PVC window profiles is to provide heat and sound insulation in an healthy way, heat losses caused by the support sheets that are supposed to strengthen the PVC window profiles hinders serving the purpose. There have been many developments made to present to increase the strength of the profiles used in window and door systems. One of these developments is the invention which is the subject of the patent with publication number EP0747205 A2. The invention relates to an element inside of which comprises thermoplastic composite material and the exterior is coated with a reinforcing layer. Said product relates to creation of a fibre layer and thermosetting resin to create a reinforced structural element. With aim of increasing strenght of the mentioned said product is a product with modified contents to increase the strength, although the corner and junction points are welded by means of combining, it is weaker in comparison with the surface of the profile due to the subsequently combined fragmented structure of its.
Today, almost all the profiles comprising support sheet has the property of having support element left free in the middle part of the profile. While mounting of this support element in its location takes time, extra workforce and times are needed to place it in a location. On the other hand, these support elements manufactured mostly from metal-based material are subjected to a second coating process to prevent their being corroded. Because this process increases the production costs, it creates a disadvantage by increasing the price of the product in terms of consumer. Also in the application with no TR 2009 03272 owned by the applicant, definitions for support element, filling materials, aimed to solve some part of the problems mentioned above, manufactured from polymer blend material instead of support sheet have been made. In conclusion, presence of the need for a profile, in monolithic structure, eliminating the shortcomings of the profiles comprising support sheets existing in the prior art, manufactured together with the PVC profile with enhanced heat and sound insulation and strength and inadequacy of the existing solutions have made it mandatory to make it an improvement in the respective related art.
Purpose of the Invention
Acting on this situation of the art, the invention aims to eliminate the existing problems above.
Purpose of the invention is to produce, by bringing various raw materials that are concurrently incorporated in the production line together in the extrusion machine, a profile comprising top coated with PVC and the interior of which comprising at least one different material, with enhanced strength.
Another purpose of the invention is to provide enhancement of the strength at the corner welding fusion points of the profile, with the external profile and internal filling material manufactured together. In addition, with the external profile and filling material, additional durability properties of the profile is enhanced. The strength material and the filling material can be obtained together or separately inside the PVC external profile.
Thanks to production of the profile with empty internal cross-section and of supporting filling material and/or of the strength material as integrated form on a single line in production, time and energy spent for both the profile manufacturers and the profile processors are aimed to be reduced. The filling material is not positioned in to the profile with a separate process or operation, and the people that produce door and windows with the profile do not need to perform a separate positioning process.
A further purpose of the invention is to be able to do shipping of the product within the same package because it becomes a single length material, termed as profile, thanks to production of the filling material and the strength material as monolithic inside of the external profile. A further purpose of the invention is to be able to achieve the production of PVC profile, which is created as welded due to the properties of the filling material and the strength material, in the machinery park wherein it is made into a product by being processed, without requiring any additional machine.
A further purpose of the invention is to provide elimination of rusting and similar shortcomings, and therefore elongation of the service life of the filling material and of the strength material positioned at the section that surrounds all of the inner part of the external profile thanks to the structural properties of theirs.
The profile creates a whole with the filling materials and the strength materials layers inside of its. Thanks to this property of the profile, performing concurrent welding of the PVC and of the filling material by the same machine on the corner sections is aimed. Thus, thanks to the filling material and the profile that are produced together, operation of window or door systems on the welding corners as a single system is achieved and faults such as sagging of the wings is prevented. Also with the strength material to be used in addition, high heat and sound insulation is provided. A further purpose of the invention is to eliminate the necessity for screws and similar connecting members, thanks to the production of the strength material and the filling material with high heat and sound insulation properties together in the profiles produced by the method according to the invention. A further purpose of the invention is to completely eliminate the negativisms that may emerge during storage and shipping of the support sheets positioned subsequently inside of the profile in the production stage in the prior art, revealing a profile not requiring such a process, of additional stacking and shipping found with the profile. To realise all the advantages that are mentioned above and that will be understood from the detailed description below, the present invention is a method concerning production of the profile comprised of a PVC material surrounding the exterior of the filling material contained in the inner part of its, positioned in to the interior of its and comprising strength material in monolithic structure with said filling material, and is characterised in that; it comprises the operation steps of

Detailed Description of the Invention
In this detailed description, preferred embodiments of the production method of the profile (1) according to the invention are described only for a better understanding of the subject-matter and not to constitute any limiting effect. The filling material (2), the strength material (3) and the PVC material (4) used for the production of a profile (1) in monolithic structure are given for comprehension of the method. By preference, it is possible to obtain, by using different materials, profiles (1 ) having various properties with this system.
For production of a profile (1 ) in monolithic structure by the method according to the invention, the materials (2,3,4) with various properties are processed at the extrusion machine (6) at the same time. These materials (2,3,4) are integrated without being bonded with one another or being fitted with connecting members such as screws, and similar. In the application mentioned in this detailed description, the interior part of the profile (1 ), which is empty, obtained by the method according to the invention is coated with a filling material (2) providing sound and heat insulation and with the strength material (3) increasing the internal and external strength of the profile (1 ). On the other hand, PVC material (4), surrounds the external surface of the filling material (2) contained in the interior part of the profile (1 ). That coating process is achieved by means of extrusion. Extrusion basically involves the principle of transforming granules of the materials (2,3,4) used into molten form under pressure and then cooling those molten materials (2,3,4) along the mould by forming a shape.
Profiles (1 ) are generally produced in a cubicle (5) structure splitting into compartments with small internal volume for prevention of heat losses. These cubicles (1 ) can be created in various volumes and structures. Heat losses are reduced, because of the interior part of the profile (1 ) is split into small compartments. While the strength material (3) surrounds the inner walls of these cubicles (5), the filling material (2) takes up a volume remaining between the PVC material (4) starting from the external surface of the cubicles (5).
Said filling material (2) is a composite structure, being a blend material manufactured preferably from polymer and natural fibre material The strength material (3) is manufactured preferably from fibre glass staple sliver material and the PVC material (4) is manufactured from polyvinyl chloride.
The extrusion machine (6) providing production of a profile (1 ) in monolithic structure according to the invention comprises
• the strength - providing filling material (2) and the strength material (3) surrounding the inner surface of the profile (1 ) that provide high heat and sound insulation, and the different raw material inlets (6.1) providing putting into process of the plastic - based PVC material (4) that surrounds the external surface of its,
• the assembling department (6.2) wherein raw materials entries of which are made from different points are combined,
• the cooling channel (6.3) wherein the profile (1) comprised of the strength, filling and PVC materials (3,2,4) is created in monolithic structure is cooled,
• the moulding section (6.4) wherein the profile (1 ) is shaped up from the combined and cooled materials in line with the purpose of use.
The method concerning production of a profile (1) in monolithic structure:
The extrusion machine (6) has a separate raw material inlet (6.1) for each material (2,3,4) required for the production of profile (1). Therefore, the filling material (2), the strength material (3) and the PVC material (4) are concurrently supplied to the extrusion machine (6) from different material inlets (6.1). The silo wherein each material (2,3,4) found is different. When a profile (1) in monolithic structure is desire to be produced with more materials, a new raw material inlet (6.1) is added to the inlet of the extrusion machine (6). The materials (2,3,4) taken from the raw material inlets (6.1 ) to the extrusion machine (6) are turned into melt under pressure as the result of heating up of a bucket coated with hot plate by means of an engine. These molten materials (2,3,4) are subsequently assembled in the assembling department (6.2) of the machine (6). After assembly of said filling material (2) in a way to surround the top of the strength material (3) and the PVC material (4) surround the filling material (2), the single piece material obtained is transferred to the moulding section (6.3). Then the profile (1) taken to the moulding section (6.4) is shaped up according to the location wherein it will be used. Thus, the filling material (2), the strength material (3) and the PVC material (4) forming the profile (1) are processed by means of the same mould.
The profile (1) in monolithic structure shaped up at the moulding section (6.4), wherein all the materials (2,3,4) are the found all together is taken to the cooling channel (6.3) comprising liquid flow to cool the materials positioned in the inner part of its (2,3). That cooling channel (6.3) provides preservation of the form and the shape given to the profile (1 ) during hardening of its. The profile (1) going out of said cooling channel (6.3) becomes ready to be dispatched to the location where it will be used by being packaged directly. There is no need to carry out the processes such as cutting, screwing, bonding and similar prior to packing because the strength - increasing support element (2), manufactured from polymer blend material, that provides high heat and sound insulation and the strength - increasing material (3) manufactured from fibre glass staple sliver material have been placed and bonded into the profile (1 ) obtained. During turning of the profile (1 ) obtained by the method according to the invention into the frame form for use in window and door system on the other hand the filling material (2) and the strength material (3) being in profile (1) form inside of the profile (1 ) are welded by means of the machines with which the profile (1 ) is welded and thus the strength on the corner parts is increased.
In an alternative embodiment of the invention, it is possible to obtain a profile (1 ) in monolithic form using at least two different raw materials by the method according to the invention. As seen in Figure 4, on an extrusion machine (6) comprising two raw material inlets (6.1 ), the strength material (3) can be used to fill up the inner surface remaining below the PVC material (4). Thus, a profile (1 ), comprised of the materials (3,4) integrated with one another during production, the interior part of its, which is empty, is surrounded by the strength material (3) and the upper surface on the other hand is surrounded by the PVC material (4).
