Description

A floor mat and a preparation method thereof Technical Field

[0001] The present invention belongs to the technical field of floor mats, and in particular relates to a floor mat and a preparation method thereof. Background Art

[0002] Floor mats are a product that effectively removes dirt and moisture at entrances, keeping indoor floors clean. They are flexible, soft, and comfortable to the touch. Their unique UV-resistant additives prevent fading and brittleness, making them durable enough to withstand outdoor exposure to the sun and rain.

[0003] For example, a plush floor mat and a preparation method thereof disclosed in announcement number CN101773361A have fine pile, compact packaging, and are easy to carry compared to carpets. They are easy to assemble and use after purchase, can be partially replaced, and are economical and practical. Compared with traditional carpet-spliced ​​floor mats, they have a finer touch, are warm and cold-resistant, have diverse colors, are more freely matched, and are more beautiful and fashionable. However, they do not solve the problems existing in existing floor mats and preparation methods thereof: because floor mats are often placed at the door of the bathroom and the floor is often tiled, they are easy to slip in the event of dripping water, reducing safety of use. At the same time, the surface of the floor mat is the part most prone to water splashing. Due to its low water absorption, water is easily present on the surface of the floor mat, which also makes it easy to slip. In addition, bacteria are easily grown if the floor mat is placed for a long time. For this reason, we propose a floor mat and a preparation method thereof. Summary of the Invention

The volcanic rock particles have water absorption and anti-slip properties, which can be beneficial to improving the body environment. The unique "breathing" function can regulate air humidity.

[0122] Principles and advantages of the present invention:

[0123] The bottom layer 1 of the present invention adopts a base material layer of PVC or natural rubber or TPE mixed with volcanic rock particles, and utilizes the hardness, wear resistance, weathering resistance and corrosion resistance of volcanic rock to make the floor mat have high strength and tensile strength, thereby reducing the occurrence of cracking of the floor mat. At the same time, the base material layer made by adding volcanic rock particles has water absorption and anti-slip properties. In addition, the back of the bottom layer 1 of the floor mat adopts a rough surface design with certain patterns, which is conducive to improving the anti-slip property of the floor mat and increasing the safety of use. By providing an antibacterial layer 2, the antibacterial effect of the floor mat can be increased, the breeding of bacteria can be reduced, thereby improving the protection of the human body. By providing a water-absorbing layer 3, the water absorption capacity of the floor mat surface can be increased, the wetness of the floor mat surface can be reduced, and the occurrence of slipping can be further reduced. The present invention uses fly ash, an industrial waste, as a binder for the water-absorbing layer 3, which not only saves natural resources such as raw ore but also reduces the pollution of waste to the ecological environment. The addition of volcanic rock can also enhance heat resistance, while the addition of sodium bicarbonate can increase the water-absorbing layer's ability to decompose oil, making it suitable for kitchen use. The provision of the pile layer 4 not only improves foot comfort but also increases the contact surface with water through the pile fiber structure, achieving better water absorption. Furthermore, the pile fibers produced after polishing are partially embedded in the base layer 1, forming a bond with it. This allows the pile fibers to be pumped through to quickly drain water to the base layer 1, preventing any accumulation and improving drainage speed.

[0124] The following experiments were conducted on floor mats made with a traditional process and floor mats made with the process of the present invention. The experimental contents and results are shown in the following table: Tensile strength Wear resistance Water absorption Anti-slip property Antibacterial property Traditional floor mat 100% 100% 100% 100% Example 1 105% 112% 114% 110% Example 2 109% 116% 117% 109% Example 3 110% 118% 119% 115%

[0125] Through various experiments, it can be found that the tensile strength, wear resistance, water absorption and anti-slip properties, and antibacterial properties of the hollow yarns prepared in Examples 1, 2 and 3 are all improved, and Example 3 is the best example.

[0126] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The prepared bottom layer (1), antibacterial layer (2), and water-absorbing layer (3) are placed in a pressing machine from bottom to top, and hot-pressed to obtain a semi-finished floor mat; S5. Grinding the surface of the semi-finished floor mat to form a fluff layer (4) to obtain a finished floor mat.

7. The method for preparing a floor mat according to claim 6, wherein: The specific method for preparing the bottom layer (1) in S1 includes: S101. A substrate of one of PVC, natural rubber, or TPE mixed with volcanic rock particles is applied to the substrate surface using a high-temperature roller at a temperature of 120°C to 180°C for 4 to 6 minutes. After the roller is heated, the surface is scratched until acceptable. S102. The back of the substrate is subjected to heat molding treatment to form a rough surface with certain textures on the back; S103. According to the processing size requirements, the substrate processed on both sides is cut into suitable finished products to obtain the bottom layer (1).

8. The method for preparing a floor mat according to claim 6, wherein: The preparation of the antibacterial layer (2) in S2 specifically includes the following steps: S201 prepare the following raw materials in parts by weight: 12-18 parts of sodium alginate, 4-6 parts of fine-porous silica gel and 4-10 parts of nano-titanium dioxide; S202. The fine-porous silica gel was mixed at a mixing temperature of 140 degrees -150 degrees, and the average mixing time was 380-400 seconds to obtain a masterbatch; S203. The masterbatch is mixed with sodium alginate and nano-titanium dioxide and further mixed at a mixing temperature of 110-120 degrees and an average mixing time of 350-370 seconds; S204. The rubber obtained in S203 is further mixed by adding a vulcanizing agent, the mixing temperature is 60-70 degrees, the mixing time is an average of 230-250 seconds to obtain cooked rubber; S205. The obtained cooked rubber is sheeted and molded to obtain an antibacterial layer (2).

9. The method for preparing a floor mat according to claim 6, wherein: The preparation method of the water absorbing layer (3) in S3 specifically includes: S301. The waste paper bags are shredded, diluted with water, stirred to a mass concentration of 20-40%, then sieved, diluted with water, and adjusted to a concentration of 6%-8% wood pulp fiber slurry; S302 according to fly ash: calcium hydroxide: Portland cement is 1:0.2-0.4:0.15-0.3 weight ratio mixed to form a binder; S303 take resin, volcanic rock, sodium bicarbonate raw materials, according to the resin: volcanic rock: sodium bicarbonate is 1: 0.4-0.7: 0.1-0.3 weight ratio mixed and beaten into a slurry, the slurry method to form a thin layer of blank, the thin layer of blank formed into a slab by the forming cylinder; S304. After the slab is continuously rolled with five rollers with step-by-step pressure, it is demoulded, dried, and polished to obtain a water-absorbing layer (3).

10. The method for preparing a floor mat according to claim 9, characterized in that: The method for preparing the fluff layer (4) in S4 is specifically as follows: the water-absorbing layer (3) is polished by a sand belt, and the fluff fibers of the resin skin of the water-absorbing layer (3) are polished out by utilizing the uneven structure of the sand belt surface, thereby forming the fluff layer (4).
