Decorative panel and method of manufacture

The invention relates to a heat-insulating decorative panel which is extremely versatile. It is common practice to use wood or fiber board to be covered with fine wood veneers. According to the invention Purnier in the form of thin plates made of wood laminate, metal or other materials on a foam board is preferred Glued on made of Styrofoam, whereby a reinforcement frame made of wood or wood fiber can be provided.

A plate designed in this way gives the following advantages:

1) Walls, doors etc. in houses, offices etc. can be included domestic or foreign precious woods are decorated with a quarter of the price of a normal wood paneling, , ■ -. · ■, -.

2) excellent thermal insulation and protection against cold, heat, moisture and sound is achieved,

3) the acoustic properties are improved and the Increases the comfort of the rooms,

1098Λ3 / 0-97!

4) as a result of the favorable thermal insulation, savings can be made for heating and cooling devices,

5) the sound insulation prevents eavesdropping in adjoining rooms,

6) paneling made with panels according to the invention is effective very decorative and appealing,

7) the paneling according to the invention is insect-proof and has none disadvantageous aging properties,

8) the paneling can be adapted to any curve or column curvature after simply moistening the wood veneer panel beforehand "become noticeable without bumps or holes in the walls will,

9) the manufacturing price is extremely low,

10) the attachment is easier than the conventional paper wallpaper, since you can do without guides or retaining strips; in the case of new houses, the walls do not even need to be plastered,

11) the paneling is completely insensitive to cracks on the outside, Cracks or breaks that may later appear in the underlying walls.

The plates or panels designed according to the invention can be on easiest by means of impact adhesives on walls or ceilings be determined.

Panels designed according to the invention can also be used to partition rooms can be used, with metallic slot profiles being expediently used as a framework and another Veneer panel with mesh reinforcement if necessary on the opposite side of the wooden panel and mesh reinforcement provided area is attached.

The invention makes full use of one thing among other features unknown phenomenon, namely the behavior of a living material (wood) towards a dead material (polystyrene).

The following elements and materials are used to carry out the method according to the invention:
1. Styrofoam or similar material, density 20 to s> 0, cured for a few weeks in order to achieve the hardness required for the lost enamel. The thickness of the material is between 10 and 50 mm, depending on the

thermal-acoustic insulation properties. 2 »Mesh reinforcement or soul. It's about the wood or horz ^ lomerate, which is used in plywood manufacture.

It is imported by rolling out mostly from Guinea Won wood starch.

3. Thin wooden board or plastic laminate for the visible Area of the paneling. The first type includes all domestic and foreign types of wood found on the Harkt with a usual thickness of 0.6 to 0. fc mm. The plastic laminate is tinter the designation "Formica", "Railite" etc. on the market"

4. Cold adhesive made from vinyl polypropionate and vinyl polyacetate with the highest concentration of the resins and the lowest concentration of the aqueous solvent to achieve hardening in oO to 90 minutes, depending on whether it is in summer or in Winter is applied to allow, at any time, one minimum hardening temperature of at least 20 ° C remain.

5. Impact adhesive, liquid and free of all solvents that are derived from benzene, for application with a brush or even with a spray gun * This adhesive is used * the finished Paneling made of styrofoam and wood or plastic laminate of any kind to be attached to the wall or ceiling.

The method according to the invention is carried out in the following manner leads:

The thin wooden panels and the reinforcement made of wood conglomerate are made in the manner of the usual plywood factory processes prepared and made to measure in terms of thickness. The styrofoam plate is prepared using a specially prepared one Grinding machine sanded evenly to the desired thickness. Now glue is applied to both sides of the conglomerate core by means of a brush, roller or dosing device. On one surface of the reinforcement lake the thin wooden board or the plastic layer is then placed on top and the styrofoam board on the other side. The so The laminated body produced is then placed in a hydraulic cold press for 60 to 90 minutes (depending on the humidity) pressed. Then the layered bodies are removed and stacked to dry. The individual layer bodies are by placing small polystyrene plates in between separated. The temperature of the room is kept at a constant 20 to 25 ° C. Because all three components of the layered body namely the veneer plate, the core and the styrofoam layer, suck in the water contained in the adhesive, otherwise there is a risk of strong contraction or bending, whereby the wood is convexly curved outwards.

However, if such a bend is desired to make paneling on columns or arches, the reverse can be done by adding moisture a corresponding curvature can be produced precisely and without risk of damage.

The usual drying time at the stated temperature is 2 to J5 days. After that, the panels are completely rigid, smooth and level and can be cut, sanded, polished, polished and / or painted as required.
