DE202004018259U1 - Wood-based laminated floor covering with butyl sub-surface seal and bonding agent - Google Patents

Abstract

A laminated parquet floor covering material is a wood-based block with a butyl sub-surface seal and bonding agent. The block has three layers whose centre layer is cut from an upright array of rods. In alternative embodiments the middle layer is a high density fibreboard on a paper underlay, chipboard with a paper underlay, or high density fibreboard sandwiched between layers of cork.

Description

Laying of finished parquet

The Laying of prefinished parquet according to DIN Norm is published so far in two variants.

Variant 1: Floating laying

The Floating installation involves that the engineered flooring is not adhesive but is laid floating. The subsurface (dryness) must according to the recommendation be prepared by each Fertigparkettherstellers. On this Underground, a vapor barrier (PE film) is laid out across the board. Thereon the finished parquet is laid according to the manufacturer's instructions.

Advantage variant 1

• - Fast laying
• - By novel connection systems occur only minor installation errors.

Disadvantages Variant 1

• - bumps are hardly cushioned.
• - sound insulation values are significantly lower than the glued parquet.
• - That Strong work on the parquet surface leaves joints open and thus water penetration. (Deterioration).

Variant 2: Bonding in the adhesive bed

These Variant is characterized by being prepared accordingly Substrate is applied an adhesive. Then it will be Prefabricated parquet placed in the adhesive bed. For the different substrates are to take the respective adhesive and preparatory measures.

Disadvantage variant 2

• - laying only recommended by the expert.
• - Two independent operations (Apply glue, lay parquet).
• - Odor nuisance through the glue in the first days after laying.

description

butyl is a thermoplastic adhesive sealant based on synthetic Rubber with very good shut-off function against water vapor and sound-absorbing Properties.

The Material is suitable for Fassschmelzanlagen and is used for fixations that are not mechanical Transmit forces have to.

properties

No-sweat, aging and weather resistant. Butyl releases no flammable vapors and is odor-free at room temperature. It fulfills the conditions of the EC 1 classification. Technical specifications Chem. Basis: thermoplastic synthetic rubber Colour: brown (colored) Density: 1.5 g / ml Penetration: 45 +/- 10, 1/10 mm (150 g cone, 20 °, 5 sec.) Solvent: none Liability: on dry and clean surfaces Barrel Melting point: 120 °

Combination of the elements

By a special production process is the butyl on the back applied a finished parquet.

production

outgoing from a production in a parquet plant should the production in the ongoing process of manufacturing meaningful at the Be integrated where the finished formatted panel / plank enters the packaging.

In detail

The Panel is horizontal on the conveyor belt (Top layer up) led into the plant, where the butyl in one Barrel to a melting point (120 °) With the help of a roller (nozzle) the material is on the back of the panel (Gegenzugseite) applied. The order thickness determines the Fixation and cold flow behavior of the material. Right after the Apply a protective film is applied so that the butyl is not can stick with other planks in the box, which later embarrassed of the element must be removed. The protective film is called roll material fed to the bottom of the panel and covers the entire adhesive surface.

The Coater is set to fit exactly on plank width Butyl can be applied. Through a Kappstation, the material becomes capped front and back.

Of the in the protection claim specified invention is based on the problem to provide a stable, level, sound and insulated floor covering, the fast and self-adhesive (fixing) and uncomplicated self laid can not be and by moisture and other influences in quality loses.

The Become in the previously used methods problems solved by the features listed in the protection claim.

• – Einfaches Verlegen auch durch den Endverbraucher.
• – Hohe Schalldämmeigenschaft.
• – Ausgleich von Untergrundunebenheiten < 2 mm auf Dielenlänge
• – Einsparung von einem Arbeitsgang.
• – Laufeigenschaften wie bei verklebten Fertigparkett.

By combining the elements, the following advantages are achieved:

• - Easy laying even by the end user.
• - High sound barrier property.
• - Compensation of substrate unevenness <2 mm on plank length
• - saving of one operation.
• - Running characteristics as with glued finished parquet.

Laying the new element

The considered as prior art longitudinal and transverse connection usually called click connections.

When best connection has a screw-in click connection the long side exposed of the panel, which in addition in the top edge processing is to lock from above. Head edging horizontally need to be locked are not considered to be suitable because of the contact of the butyl with the substrate an immediate fixation takes place, the only about 1/10 mm margin allows.

horizontal Suggestive click connections can basically be used for this type of item as an application be excluded.

Claims (3)

Prefabricated parquet with butyl for fixation on the substrate, characterized in that a) finished parquet in three-layer construction, middle layer with sticks of standing annual rings b) pre-finished parquet, with HDF middle layer and reverse paper backing c) laminate with HDF middle layer and reverse paper backing d) laminate with chipboard middle layer and Back of counter-paper e) Cork finished parquet with HDF middle layer, back cork in return f) OSB, raw g) OSB with finished surface h) ESF raw i) ESF with finished surface j) Solid wood planks with butyl, in the necessary mixture for the respective substrate (screed, plank flooring, ceramic substrate, smoothed Esrich) and application strength on the back of the board is connected in the production process to a unit. Prefabricated parquet according to protection claim 1 characterized in that, the butyl layer on the backing (plank) of 0.3 mm is applied to 1.5 mm thick. Prefabricated parquet according to protection claim 1 characterized in that the serial employment also by a thermal transfer Process the butyl individually as long runs on the back of the vehicle can be applied.
