Description

   Plastic floor tile with adsorption structure and manufacturing method thereof   

The invention relates to a plastic floor tile; more specifically, it relates to a plastic floor tile with an adsorption structure.

At present, when plastic floor tiles on the market are installed, they are mostly glued to the building surface of the building. However, in addition to the glued plastic floor tiles, they need to be coated with adhesive during installation, which increases labor. Time and material cost, and after the plastic floor tile is removed, the plastic floor tile will be damaged due to the tearing of the adhesive, and it cannot be used again.

In order to solve the above-mentioned shortcomings, the inventor of this case has also proposed a solution. Please refer to Chinese Patent Bulletin No. I496976, that is, the design of the joint groove connects the plastic floor tiles and the plastic floor tiles and lays them on the construction surface to replace Application of adhesive on plastic floor tiles.

However, although the plastic floor tiles connected through the joint grooves can be set on the construction surface in a large range, the plastic floor tiles lack the adhesion between the bottom surface and the construction surface. Therefore, when the cutting length of the plastic floor tiles does not match the length of the laying range, it is easy to Slipping due to the gap.

The problem to be solved by the present invention is to use the "pressing out the physical adsorption structure when rolling" to improve the problem of using "adhesive for plastic floor tiles".

In order to solve the above problems, the present invention discloses a plastic floor tile with an adsorption structure. The structure includes: a base material layer having an upper surface and a lower surface facing away from the upper surface; and a bottom surface layer attached to the bottom surface layer. The bottom surface of the lower surface of the base material layer, a bottom surface remote from the base material layer, is provided with a plurality of physical adsorption structures formed in a rolling manner, and the adsorption structures are used to directly contact and attach to a building surface.

In one embodiment, the plastic floor tile further includes a printing layer bonded to the upper surface and a fabric layer covering the printing layer.

In the above embodiment, an adhesive layer may be adhered between the upper surface and the printing layer.

In one embodiment, the adsorption structure is composed of a plurality of sucker-shaped pits recessed on the bottom surface of the bottom surface layer, and is arranged in a dot-shaped square array, a dot-shaped circular array, or a dot-interlaced staggered manner .

As mentioned above, the steps of the method for manufacturing a plastic floor tile without an adhesive layer include the following steps: 1. A plastic extruding step: the raw materials of each layer are blended according to the ratio and then mixed into a mixer to complete the raw material mixing process and plasticized After the procedure, the extruding process is completed by an extruder; 2. A roll laminating step: the bottom surface layer and the substrate layer that are separately extruded in advance are simultaneously introduced into a T-shaped extruder for the T-type extrusion process, and the bottom layer and the The base material layer is combined with a T-shaped extruder to form a predetermined thickness after being rolled. The roll sheeting process is completed as a material sheet, and then the bottom surface layer of the material sheet to be embossed and the pre-formed fabric layer are layered. The preheating process is softened, and then the material sheet and the pre-formed printing layer and the fabric layer are embossed and bonded with a set of embossing rollers to become a semi-finished plastic floor tile. 3. A cooling and tempering step: The plastic floor tile semi-finished product is subjected to a cooling process, and a tempering device is used to perform a tempering process on the plastic floor tile semi-finished product; and 4. a die-cutting step: after the plastic floor tile semi-finished product has completed the tempering process, Formed by punching the semi Plastic tiles cut to the desired dimensions.

Another example is the plastic floor tile. The method for manufacturing a plastic floor tile with an adhesive layer includes the following steps: 1. A plastic extruding step: the raw materials of each layer are blended in proportion according to the ratio, and then mixed into the mixer to complete the raw material mixing process and plasticized. After the procedure, the extruding process is completed by an extruder; 2. A roll laminating step: the bottom layer, the substrate layer and the adhesive layer that are separately extruded in advance are simultaneously introduced into a T-shaped extruder for the T-shaped mold extrusion process, The bottom layer, the substrate layer and the adhesive layer are combined by a T-shaped extruder to form a predetermined thickness by rolling, and the rolling sheet is completed into a material sheet, and then the material sheet is subjected to an embossed bottom layer and The pre-formed fabric layer is softened by a layered pre-heating procedure, and the material sheet and the pre-formed printing layer and the fabric layer are embossed and bonded with a set of embossing rollers to become a semi-finished plastic floor tile; 3. A cooling and tempering step: the plastic floor tile semi-finished product is subjected to a cooling process, and a plastic tempering device is used to perform a tempering process on the plastic floor tile semi-finished product; and 4. a die-cutting forming step: the plastic floor tile is semi-finished After completing the program back to the fire, and then shaping the semi-finished plastic tiles cut to the desired dimensions by punching.

In the above two manufacturing methods, the bottom surface layer of the material sheet is preheated by a first embossing roller to press out a sucker-like recess on the bottom surface of the bottom surface layer, and the fabric layer is preheated by a second embossing roller. The first embossing roller and the second embossing roller can simultaneously press the material sheet and the printing layer and the fabric layer into a single body. .

In the above two manufacturing methods, after the layered pre-heating process of the roll lamination step, an unrolling process may be first performed to overcome the soft wrinkles of the printing layer and the fabric layer during the conveying process, so that the printing The layer and the fabric layer can be completely flat bonded to the upper surface, and then enter the embossed bonding process.

In the above two manufacturing methods, before the cooling and tempering step, a trimming and cutting step may be performed to make the width of the semi-finished plastic floor tile uniform.

The main feature of the present invention is that, by using the texture design of the embossing roller, a physical adsorption structure with an adsorption effect can be formed by rolling on the bottom surface of the plastic floor tile during the process of manufacturing the plastic floor tile, instead of the conventionally applied adhesive. gum.

In this way, the present invention can use its own physical structure to achieve the purpose of attaching to the building surface without the need for adhesive coating. Not only can the labor and material costs of adhesive be saved during installation, but also When dismantling, keep the integrity of the plastic floor tiles for re-laying.

Next, the present invention will be further described with reference to the drawings and specific embodiments, so that those skilled in the art can more easily understand the present invention and implement it.
