Floor covering for wet areas and process for their

CONFECTION

Field of innovation [001] The present invention deals with a floor covering for wet areas, more specifically a synthetic floor for application in wet areas or recreation areas, made with at least two layers of colors in an extrusion process only.

History of innovation [002] The coating of damp areas, such as swimming pools, saunas, hot tubs and, notably, the floor of vessels, is currently using synthetic coatings of the most diverse types and materials, such as ethylene-vinyl acetate (EVA), polyvinyl chloride (PVC), among others.

[003] Such materials are resistant, waterproof and, in different degrees, allow the maintenance of their cleaning, avoiding the degradation or accumulation of dirt.

[004] Its ease of handling allows you to configure parts of different sizes and profiles, facilitating their adaptation on the most diverse surfaces and cutouts, with quick and simple application.

[005] However, the color configuration is still an obstacle to be overcome, since the pieces are either made in a single color or require a combination of different parts to provide different colors for the final application.

[006] The patent MU8901003-5 presents an alternative to provide a finish with at least one additional color to a piece, however, which requires intense manual work.

2/4 [007] It was in this scenario that the innovation solution presented here was developed, which consists of a piece for application in wet areas that presents at least one additional color to the final aspect, whose manufacturing process takes place through extrusion set of layers with the colors to be presented in the final piece.

Description of the figures [008] Figure 1 represents a schematic view of the process of the present innovation, where the association between the raw material silos (ΙΑ, 1B), the extruders (2A, 2B), the extrusion head (3) is perceived , extruded layers (IA, 1B) and calender rolls (5).

[009] Figure 2 represents a sectional view of the coating of the present innovation, where its two layers (4A, 4B) and the groove (6) that allow the exposure of the lower layer (4B) are perceived.

[010] Figure 3 represents a top view of the coating of the present innovation, where the upper layer (4A) and the design formed by the groove (6) that allow the exposure of the lower layer are perceived.

Detailed description of the innovation [011] This innovation deals with a coating applicable in areas subject to humidity, such as around swimming pools, bathtubs, hot tubs, in recreation areas, such as playgrounds, or on boat floors, where the need for a non-slip, washable and moisture-resistant surface is necessary.

[012] The coating of this innovation is made from polymeric resins, such as PVC, in a traditional extrusion process, where the raw material is stored in silos (ΙΑ, 1B) to feed at least two extruders ( 2A, 2B), which send the molten material to a

3 / * flat head (3) (f / at d / e) for forming a continuous blanket with at least two layers (4A, 4B), which is pressed by calenders (5) for compacting and finishing, as illustrated in Figure 1.

[013] In this process, the positioning of the extruders (2A, 2B) at the entrance of the flat head (3) determines the formation of the two overlapping layers (4A, 4B), while regulating the outlet pressure of each extruder (2A, 2B ) determines the thickness of each layer (4A, 4B).

[014] The blanket thus formed is composed, in a preferential configuration, of two layers (4A and 4B), fused together, in a single body, where each layer (4A, 4B) would present a different color. Obviously, for a technician in the subject, the insertion of additional layers through extruders positioned on the head (3) is a possible variation. However, in order to facilitate the explanation, we will limit the example for the case of a two-layer blanket.

[015] In a preferred configuration, the coating still undergoes processing steps, such as sanding its surface, using sandpaper weight between 10 and 300, in order to increase its roughness and, consequently, the adhesion to allow the use safe in wet areas.

[016] To form the final product, the blanket (4A + 4B) formed is subjected to a process of removing the upper layer (4A), by means of a cutter or by means of manual instruments, aiming at the exposure of the lower layer (4B), as shown in Figure 2. In this way, the coating can be grooved, increasing its adhesion to the touch and enabling the formation of designs or patterns, as shown in Figure 3.
