Description

Technical Field

[0001] This utility model belongs to the field of plastic floor mat technology, specifically relating to a PVC floor mat. Background Technology

[0002] The aforementioned PVC floor mats are widely used in home settings (such as bathrooms and hallways), public places (such as hospitals, shopping malls, and sports venues), and special locations (such as near swimming pools, laundry rooms, and indoor flooring in kindergartens).

[0003] Existing PVC floor mats are generally made by foaming PVC resin with various additives and fillers into sheets, which are then cut to specific dimensions. Adding colorants to the additives yields sheets of the desired color. Since these sheets are bare materials, the various sizes obtained, and even the interlocking structures formed at the edges to achieve the desired coverage area, are essentially exposed PVC floor mats. Exposed single units of small-area PVC floor mats, and large-area floor mats formed by splicing, have the following shortcomings: poor physical properties, specifically, unsatisfactory tensile strength, tear strength, and abrasion resistance; poor chemical stability, specifically, inability to resist chemical corrosion, affecting the floor mat's ability to maintain good performance under special environments. In particular, PVC undergoes denitrification and dehydrogenation at high temperatures, causing degradation reactions. The release of hydrogen chloride not only affects the performance of PVC but may also harm human health; and recycling after disposal is relatively troublesome.

[0004] Considering factors beyond those mentioned above, exploring PVC floor mats that improve tensile strength, tear strength, abrasion resistance, and resistance to chemical corrosion, while also meeting the requirements for use in certain special environments, is of positive significance. The technical solutions described below arose in this context. Utility Model Content

[0005] The objective of this invention is to provide a PVC floor mat that helps to significantly improve tensile strength and tear strength, enhances abrasion resistance, helps to prevent chemical intrusion and thus significantly extend its service life within a reasonable period, and meets the requirements for use in special environments.

[0006] The present invention accomplishes its objective as follows: a PVC floor mat, comprising a PVC substrate, characterized in that a first adhesive film layer is integrally bonded to the upper surface of the PVC substrate, and a second adhesive film layer is integrally bonded to the lower surface of the PVC substrate; a first protective film layer is integrally bonded to the side of the first adhesive film layer facing away from the PVC substrate, and a second protective film layer is integrally bonded to the side of the second adhesive film layer facing away from the PVC substrate.

[0007] In one specific embodiment of this utility model, the thickness of the PVC substrate is 2-20 mm.

[0008] In another specific embodiment of this utility model, the thickness of the first adhesive film layer and the second adhesive film layer is 0.015 to 0.03 mm.

[0009] In another specific embodiment of this utility model, the first adhesive film layer and the second adhesive film layer are TPU adhesive film layers.

[0010] In another specific embodiment of this utility model, the thickness of the first protective film layer and the second protective film layer is 0.05 to 0.15 mm.

[0011] In another specific embodiment of this utility model, the first protective film layer and the second protective film layer are PVC color-printed film layers.

[0012] The technical solution provided by this utility model has a first adhesive film layer and a second adhesive film layer integrally bonded to the upper and lower surfaces of the PVC substrate, respectively. Furthermore, the first protective film layer is integrally bonded to the surface of the first adhesive film layer facing away from the PVC substrate, and the second protective film layer is integrally bonded to the surface of the second adhesive film layer facing away from the PVC substrate. Therefore, it helps to significantly improve tensile strength and tear strength, enhances wear resistance, and thus demonstrates a protective effect on the PVC substrate. It also helps to prevent chemical substances from directly penetrating the PVC substrate, thereby significantly extending its service life within a reasonable period. Moreover, it can meet the usage requirements of special environments such as laboratories, chemical composition analysis rooms, and various testing sites. Attached Figure Description

[0015] The first adhesive layer 11, the first protective layer 111, the second adhesive layer 12, and the second protective layer 121 mentioned above are integrally bonded to the upper and lower surfaces of the PVC substrate 1 by heating. That is, the first adhesive layer 11 and the first protective layer 111 are bonded to the upper surface of the PVC substrate 1 from the inside out, while the second adhesive layer 12 and the second protective layer 121 are bonded to the lower surface of the PVC substrate 1 from the inside out.
