Description

Technical Field

[0001] This utility model belongs to the field of desk mat technology, specifically relating to a desk mat that can prevent pen stains. Background Technology

[0002] A placemat is a protective and decorative item for dining tables or desks. Most placemats don't have a special structure; the differences lie more in their material, size, and shape. When used for dining tables, placemats are made of materials such as PVC, TPU, silicone, PU leather / artificial leather, and VA / PE foam. Each material has its own advantages and disadvantages, resulting in different characteristics for the placemat. For example, PVC can be made with a glossy, matte, or textured surface, but its disadvantage is that oil stains are difficult to remove once they penetrate. TPU material has a dense and smooth surface, is waterproof, oil-proof, and stain-resistant, and is easy to clean, but its production cost is much higher than PVC, leading to a higher price and weaker product competitiveness. Silicone also has naturally waterproof, oil-proof, and stain-resistant properties. While these mats offer the advantage of being stain-resistant and difficult to adhere to, they are easily scratched. Some mats are made by gluing together layers of different materials in a conventional way, making them prone to coming unglued. When used on an office desk, existing mats have poor breathability, preventing heat dissipation when a laptop is placed on them, leading to overheating. Hard mats, such as those used for keyboard typing, generate noise. Pen stains often appear on office desks, and conventional mats have weak stain resistance, leaving pen marks or stains that are difficult to remove effectively. This is especially problematic when children scribble on them. They can also deform due to high or low temperatures, causing them to come unglued and peel at the edges. Some mats have a strong odor, are not environmentally friendly, and pose certain health risks. Summary of the Invention

[0003] The purpose of this invention is to design a desk mat that can prevent pen stains. This desk mat can not only resist stains, but also dissipate heat, reduce noise caused by knocking, and has a strong ability to prevent pen stains.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A desk mat that prevents pen stains is composed of a first silicone layer, a second polyester layer, a third PVC layer, and a fourth non-woven fabric layer from top to bottom. The desk mat has a frame in the middle, and a sub-mat or heat sink is provided inside the frame.

[0006] Furthermore, the lower surface of the silicon layer is provided with a matrix of grooves, and the upper surface of the polyester layer is provided with a matrix of protrusions. The polyester layer can be stuck in the grooves of the silicon layer through the protrusions.

[0007] Furthermore, the placemat has a frame hole in the middle, and an adhesive is applied around the frame hole. The frame is then bonded to the inner circumference of the frame hole through the adhesive.

[0008] Furthermore, the sub-table mat is also composed of a first layer of silicone, a second layer of polyester, a third layer of PVC, and a fourth layer of non-woven fabric from top to bottom.

[0009] Furthermore, the thickness of the heat sink is the same as that of the desk mat, the upper surface of the heat sink is smooth, and the lower surface is a heat dissipation fin.

[0010] Furthermore, the third PVC layer contains a number of fine pores.

[0011] Furthermore, the first silicone layer, the second polyester layer, the third PVC layer, and the fourth non-woven fabric layer are bonded together with an adhesive.

[0012] The above technical solution can achieve the following beneficial effects:

[0013] This utility model table mat is composed of a silicone layer, a polyester layer, a PVC layer, and a non-woven fabric layer. The outer surface of the table mat is waterproof and oil-proof, with a smooth and dense surface that prevents stains from easily penetrating and adhering, thus providing a stain-resistant effect. The middle layer, PVC, is inexpensive, comes in a variety of colors and patterns, has good waterproof properties, and contains numerous fine pores. It is soft and can effectively reduce the sound produced by tapping. The non-woven fabric at the bottom has excellent anti-slip properties, effectively preventing the table mat from sliding.

[0014] This utility model has a frame in the middle, in which a sub-table mat or heat sink is installed. It can be used for dining or office purposes. If used for dining, the sub-table mat can be installed in the frame. If used for office purposes, especially when it is necessary to place a laptop, a heat sink can be installed to transfer the heat of the laptop to the table mat.

[0015] The surface silicon layer of this invention provides strong anti-pen stain resistance. Pen marks and stains can be removed simply by wiping the silicone pad. It also has the characteristics of high temperature resistance and low temperature resistance. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figure 1-3 As shown, a desk mat that prevents pen stains is composed of a first silicone layer 4, a second polyester layer 3, a third PVC layer 2, and a fourth non-woven fabric layer 1 from top to bottom. The silicone layer is made of silicone material, which is waterproof and oil-proof, with a smooth and dense surface that prevents stains from easily penetrating and adhering, thus providing a stain-resistant effect. Its lower surface has a matrix of grooves, and the upper surface of the polyester layer has a matrix of protrusions. The polyester layer can be held in place by the protrusions within the grooves of the silicone layer, increasing the adhesion between the silicone and polyester layers. The third PVC layer has several fine pores, a certain thickness, and is soft, effectively reducing the sound produced by tapping. The non-woven fabric at the bottom has excellent anti-slip properties, effectively preventing the desk mat from sliding. A frame 5 is located in the middle of the desk mat. Adhesive is applied around the holes of the frame, and the frame is bonded to the inner periphery of the holes through the adhesive. The frame can be made of a soft material. Sub-desk mats or heat sinks 6 are located inside the frame; specifically, the sub-desk mats or heat sinks 6 are glued to the inner edge of the frame through adhesive.

[0023] When the placemat is used as a placemat, the sub-placemat is fixed to the frame with adhesive, so that the placemat and the sub-placemat form a whole and are laid on the dining table to prevent stains.

[0024] When the desk mat is used as an office desk mat, a heat sink 6 is installed inside the frame. The thickness of the heat sink 6 is the same as the thickness of the desk mat. At the same time, the smooth surface of the heat sink 6 is located on the front of the desk mat (the first silicon layer), while the heat dissipation fins of the heat sink 6 face downwards, that is, on the back of the desk mat. In this way, the laptop is located at the heat sink 6, and the heat generated by the laptop is transferred away through the heat sink 6.

[0025] The first layer of the entire placemat, silicone layer 4, is made of organic silicone leather, which is resistant to high and low temperatures and has excellent stain resistance. It is resistant to oil-based markers, ballpoint pens, and markers, and has a strong stain resistance to chili oil, synthetic oil, cooking oil, fruit juice, red wine, etc. The entire placemat is made of environmentally friendly material, has a comfortable feel, a long lifespan, is not easy to curl or come unglued, is easy to clean, and has no odor.

[0026] The above descriptions are all preferred embodiments of this utility model. For those skilled in the art, any modifications to this utility model in various equivalent forms without departing from the principle of this utility model shall fall within the protection scope of the appended claims.
