LT5338B - A renewal method of baths - Google Patents

Abstract

The invention relates to renewal methods of baths. An insert is fitted in frayed bath. An insert is made from thermoplastic material. After placing an insert into bath a decorative siphon is arranged in an insert. An insert is filled with water. Aninsert is formed by thermal processing a sheet, which is fixed in a mould and is made from coextraction acetyl - butyl - styryl material and coated with acryl layer or acryl sheet, which is heated up to 180° by blowing warm weather. Due to the fact that between two surfaces of sheet is made a difference in pressure, a sheet is sucked in a mould and fixed to which. In this way is formed an insert, a spatial form of which corresponds with a bath form.

Description

TECHNICAL FIELD OF INVENTION

The invention relates to the renovation of all types of coatings for baths, sinks and other plumbing products by incorporating them into an old product insert made of thermoplastic material.

State of the art

In the art, there is a known method of renovating bathtubs, where the old bathtub is covered with a layer of varnish which, when dried, has properties similar to enamel. However, the application of this technique has several fundamental drawbacks, such as the relatively short life of the refurbished surface and the complexity of the proper coating technology.

Known method for coating baths is US6800190. However, when these baths are used for a longer period of time, their surface begins to wear out and changes its aesthetic appearance.

The object of the invention

The present invention introduces an efficient and straightforward technology for renovating baths and other plumbing products by applying a durable and aesthetically pleasing liner made of thermoplastic material to the surface of a worn product.

The essence of the invention

One of the essential features of the claimed method of bath renovation is that the bath is fitted with a liner made of thermoplastic material. The invention differs from the known methods of updating sanitary ware in that the bath liner is produced by thermoforming a sheet of coextruded acetyl-butyl-styrene coated with an acrylic layer or an acrylic sheet.

Once placed, the molded liner is fitted with a decorative siphon easily, durably and without scratching the surface. This is an additional advantage of the invention.

Smooth fitting and attachment of the liner to the surface of the bathtub body is achieved very simply by filling the liner in the bath with liquid (water).

²

The liner is formed by the heat treatment of a co-extruded sheet of acrylic-butyl-styrene embedded in a mold, coated with an acrylic layer, or an acrylic sheet which is heated to 180 ° C by blowing hot air. The pressure difference between the two surfaces of the sheet is obtained, which causes the sheet to soak into the mold to which it is attached. This creates a liner with the spatial shape of a bath.

The proposed method is suitable for renovating bath sinks and other plumbing products with a smooth surface.

Brief description of the drawings

The following drawings illustrate the invention:

The figure is a general view of the formed liner, where: 1 - the upper water deflection hole; 2 bottom water deflection hole.

Figure is an overall view of a cross section of a thermoplastic material, where: 3-acrylic layer; 5,4 mm layer of 4-coextruded acetyl-butyl-styrene.

Figure is an overall view of a cross section of a thermoplastic material and a bath after pasting, where: 5 is a cross sectional view of a layer of polyurethane foam adhesive; 6 is a cross-sectional view of the bathroom.

Implementation of the invention

The proposed method of bathtub renovation is realized by the following steps:

1) Removal of old siphon from old bath:

(a) the siphon shall be unscrewed by means of universal pliers;

b) the siphon is disconnected by turning;

2) placing the liner in the bath,

3) Marking of markings on the thermoplastic liner in places necessary for insertion of the siphon,

4) Making holes in the liner necessary for siphon placement:

(a) the holes shall be drilled at the locations marked from the bottom and from the top in the pre-inset;

(b) re-drilling at drilled locations;

(5) Adhesive coating of the bath surface prior to insertion:

(a) the surface of the bath shall be optimally covered with a layer of polyurethane foam adhesive;

(b) seal the ends of the water channels with an acetane-glass sealant;

6) The liner is physically pressed against the bath surface. Smooth fit of the liner to the body of the bathtub is ensured by filling it with liquid (cold water), approximately eliminating water leakage through plumbing channels,

7) Siphon Law:

(a) After inserting the liner, insert decorative siphons into the pre-drilled holes and screw in.

Industrial Applicability of the Invention

The invention can be used in industry.

Claims (5)

Definition of the Invention A method of renovating baths by incorporating a bath liner made of a thermoplastic material, characterized in that the liner is made from a coextruded acetyl-butyl-styrene sheet that is covered with acrylic, or by thermoforming an acrylic sheet. 2. A method according to claim 1, characterized in that the insert is placed in a bathtub and then a decorative siphon is installed therein. 3. A method according to claim 1 and / or 2, characterized in that the bath liner is evenly held against the bath by filling it with liquid. 4. A process according to claim 1, characterized in that the thermoforming is carried out by hot-air blasting a sheet molded in a mold, which, due to the difference in pressure between its surfaces, soaks into the mold and forms a surface corresponding to the bath. 5. A method according to claim 1 and / or 2, characterized in that it can be used for covering all kinds of baths, sinks and other plumbing products.
