Description

The present invention relates to a heat-melting adhesive sheet for tiles and a method for constructing tiles on asphalt, concrete bases, etc. using the same.

Conventionally, in the tile construction method using organic adhesives, the adhesive is applied directly to the concrete base floor or wall surface, and the installer spreads the liquid adhesive evenly to ensure good adhesion between the base and the tile. The tiles are lined up and bonded before the adhesive begins to harden and can be installed.

The amount of organic adhesive used in such conventional tile construction methods is determined by the weight of the adhesive used per unit area, and for synthetic rubber tiles and vinyl chloride resin tiles, the amount of organic adhesive used is approximately 0.3 to 0. Optimum adhesive layer thickness is achieved by using .4 kg/m ² and approximately 1.5-1.9 kg/m ² for ceramic and porcelain tiles.

On the other hand, in the tile installation method that uses a base agent and a hardening agent, the base agent and hardener are mixed well first, the adhesive is applied directly to the floor or wall, and the adhesive is cured by a chemical reaction by the time it is ready for application. The installer spreads the liquid adhesive evenly to ensure good adhesion between the base and the tiles, then arranges the tiles and glues them together.

When installing MMA resin tiles with an adhesive that uses a base agent and a hardening agent, in order to form an optimal adhesive layer thickness, if the base is asphalt, there is a large variation in the voids, and approximately 6. Only 2 to 8.3 kg/m ² is required, and in the case of a concrete base, only about 4.1 to 4.2 kg/m ² is required.

In addition, in the case of synthetic rubber tiles, vinyl chloride resin tiles, ceramic tiles, and porcelain tiles, the base is mostly concrete, and the amount of adhesive used for synthetic rubber tiles and vinyl chloride resin tiles is approximately 0.3 to 0. .4 kg/m ² , and approximately 1.5 to 1.9 kg/m ² for ceramic tiles and porcelain tiles.

Here, in Patent Document 1, there is a gap between a first floor finishing material made of wood provided on the surface of the floor and a second floor finishing material made of wood flooring material, plastic floor tile, tile carpet, or display sheet. In a removable floor sheet in which an adhesive layer is formed on the back side of an intervening sheet-like base layer, the adhesive layer contains 5 to 90 parts by mass of a synthetic resin emulsion based on 100 parts by mass of natural rubber latex. A removable sheet for floors is disclosed, which is characterized in that the synthetic resin emulsion has a glass transition temperature of -70°C to -15°C and an adhesive layer has a thickness of 50 to 150 μm. Masu.

However, in tile construction methods that use organic adhesives or adhesives that use a base agent and a hardening agent, the adhesive layer is evenly spread and formed in order to increase the adhesive area with the tile and increase the adhesive strength. This is an important work. Therefore, the work must be completed before the adhesive begins to harden, and special work techniques are required throughout the year, such as changing the work process and the composition of the base agent and hardening agent depending on the temperature of the construction environment.

In other words, in tile construction methods that use organic adhesives or base agents and hardeners, the curing time varies depending on conditions such as temperature, humidity, and ventilation at the time of construction, and the fluidity of the adhesive deteriorates after the pasting time. This makes it difficult to level the adhesive and form the adhesive layer, creating gaps between the tile and the adhesive, resulting in poor adhesion, so it is important to take curing time into consideration.

Furthermore, many organic adhesives and adhesives that use a base agent and a hardening agent can cause irritation or allergic dermatitis when they come into contact with the skin. In addition, inhaling volatile organic compounds and gases generated during the curing process can cause health problems for the installer and other people around them.

In this way, when installing tiles using organic adhesives or adhesives that use a base agent and a hardening agent, in addition to the health hazards caused by chemicals, the curing time may vary depending on conditions such as temperature, humidity, and ventilation during construction. On the other hand, if the adhesive has passed the adhesion time, it will not be possible to form an adhesive layer, making installation difficult and causing problems such as poor adhesion and peeling.

On the other hand, in the removable sheet for floors disclosed in Patent Document 1, the optimal material and thickness are not proposed for each usage environment or application target.

The present invention was made in view of these problems, and its purpose is to provide a heat-melting adhesive sheet for tiles, which allows selecting the optimal material and thickness depending on the usage environment and construction target. and to provide a tile construction method using the same.

In order to solve the above problems, a heat-welded adhesive sheet for tiles according to one aspect of the present invention is used to adhere a sheet heated and melted to an asphalt or concrete base and a tile, and is interposed between the base and the tile.

In this embodiment, the main components are polyethylene, polypropylene, polystyrene, polyvinyl chloride, acrylic resin, acrylic urethane resin, polyvinyl chloride, ABS resin, polyethylene terephthalate, polyurethane resin, polyolefin resin, acrylic rubber resin, and polyamide. It may be made of at least one of the resins and may be in the form of a sheet with a thickness of 250 μm to 3 mm.

In a tile construction method according to another aspect of the present invention, the thickness of the heat-melting adhesive sheet for tiles is selected according to the different voids and unevenness of the asphalt or concrete base, and the thickness is melted to perform filling work and base preparation. It is possible to form an optimal adhesive layer with the tile without having to worry about it, resulting in strong adhesion.

In this aspect, the heat-melting adhesive sheet for tiles is a melting type, and if the material temperature of the asphalt or concrete and tile on which it is laid is low, both are preheated immediately before bonding to achieve the optimum material temperature for bonding. After that, it may be placed on the installation surface and melted.

According to the present invention, it is possible to provide a heat-melting adhesive sheet for tiles that allows selection of the optimal material and thickness depending on the usage environment and construction target, and a tile construction method using the same.

Embodiments of the present invention will be described below with reference to the drawings.

The heat-melting adhesive sheet of the present invention is made by forming an adhesive into a sheet and heating it to form different voids and irregularities on the surface of the asphalt base 3 or concrete base 4, which is the installation surface, as shown in FIGS. 1 and 2. The sheet is melt-filled to form a leveled adhesive surface, and the sheet is plate-shaped with a thickness of 250 μm to 3 mm. By selecting the sheet thickness depending on the tile and base conditions used, the optimal adhesive layer can be obtained. It is characterized by being adjustable.

The main components of the heat-melting adhesive sheet are, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVS), acrylic resin (PMMA), acrylic urethane resin, polyvinyl chloride (PVC), It is made of at least one resin such as ABS resin, polyethylene terephthalate (PET), polyurethane resin (PUR), polyolefin resin (PO), acrylic rubber resin (ACM), and polyamide (PA).

Here, an example of the thickness of the heat-melting adhesive sheet suitable for the tile used and the conditions of use is as follows.
1) When the tile is made of synthetic rubber and used on a concrete base, the thickness is preferably about 0.2 mm to 0.5 mm.
2) When the tile is made of vinyl chloride resin and used on a concrete base, the thickness is preferably about 0.2 mm to 0.5 mm.
3) If the tile is made of ceramic and used on a concrete base, the thickness is preferably about 1.0 mm to 2.0 mm.
4) When the tile is made of porcelain and used on a concrete base, the thickness is preferably about 1.0 mm to 2.0 mm.
5) When the tile is made of MMA resin and used on a concrete base, the thickness is preferably about 0.5 mm to 1.0 mm.
6) When the tile is made of MMA resin and used on an asphalt base, the thickness is preferably about 0.8 mm to 2.0 mm.

In other words, the heat-melting adhesive sheet of the present invention can be installed on an asphalt base 3 or a concrete base 4, and the amount of adhesive used varies depending on the intended tile. By changing the adhesive layer, it is possible to adjust the optimal adhesion layer with similar indoor and outdoor tiles, including MMA resin tiles, synthetic rubber tiles, vinyl chloride resin tiles, ceramic tiles, and porcelain tiles.

The surfaces of the asphalt base 3 and concrete base 4, which are the bases, are not uniform and have different unevenness and porosity. By flowing and filling the adhesive, the adhesive area between the base and the sheet increases and an optimal adhesive layer can be formed.

In addition, by heating, the surface of the heat-melting adhesive sheet for tiles is leveled, allowing the installer to form a leveled adhesive surface that is less prone to gaps between the tiles and the adhesive surface without having to level the adhesive surface. It is strongly adhered to.

Heat-melt adhesive sheets for tiles do not start curing during heating, so the curing time is not greatly affected by the temperature of the installation environment, and the glass transition temperature is between 100°C and 200°C, so it can be used until just before tile installation. It can maintain a molten state.

The main components of the heat-melting adhesive sheet are, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVS), acrylic resin (PMMA), acrylic urethane resin, polyvinyl chloride (PVC), It is made of at least one resin such as ABS resin, polyethylene terephthalate (PET), polyurethane resin (PUR), polyolefin resin (PO), acrylic rubber resin (ACM), and polyamide (PA).

The asphalt base 3 and the concrete base 4 are the bases on which tiles are to be laid, and the heat-melting adhesive sheet 1 melts and fluidizes and fills voids and irregularities, allowing paint and resin to be applied to the asphalt. Tiles can be suitably laid on surfaces such as concrete blocks or concrete blocks.

In addition, heat-melt adhesive sheets, which do not contain volatile organic compounds used in adhesives such as formaldehyde, toluene, xylene, and acetaldehyde, are melted by heating, and are cured by a chemical reaction between the base material and a hardening agent. Unlike adhesives, it does not emit toxic gases.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and it goes without saying that various improvements and changes can be made without departing from the spirit thereof.
