Description

Technical Field

[0001] The utility model relates to the technical field of layered products, in particular to a double-color printed heat-insulating nonwoven fabric. Background Art

[0002] Non-woven fabrics are also called non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc. Non-woven fabrics have no warp and weft, and are not interwoven and knitted together by yarns one by one. Instead, fibers are pierced or spunlaced by physical methods to obtain non-woven fabrics. Fabrics with different thicknesses, feels, and hardness can be made. Non-woven fabrics are moisture-proof, breathable, flexible, thin, inexpensive, recyclable, and have high consistency in all-directional performance. They can be used in different industries.

[0003] Existing non-woven fabrics are generally used in situations where heat transfer needs to be blocked, such as building insulation, automotive interiors, packaging materials and other fields. However, non-woven fabrics without an insulation layer will not be able to play their due role in these application scenarios, limiting their market application scope and greatly reducing their market competitiveness. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a two-color printed thermal insulation non-woven fabric, which can solve the problem that non-woven fabrics are usually used in occasions where heat transfer needs to be blocked, such as building insulation, automobile interior, packaging materials and other fields, but non-woven fabrics without a thermal insulation layer will not be able to play their due role in these application scenarios, which limits their market application scope and greatly reduces their market competitiveness.

[0005] To achieve the above object, the utility model provides the following technical solution: a two-color printed heat-insulating non-woven fabric, comprising a non-woven fabric layer, wherein a first wear-resistant layer is connected to the lower end of the non-woven fabric layer by internal heat-pressing bonding;

[0006] The upper surface of the first wear-resistant layer is connected with a waterproof layer by heat-pressing bonding;

[0007] Wherein, a waterproof cavity is opened on the surface of the waterproof layer;

[0010] Wherein, a wear-resistant cavity is provided on the outer surface of the second wear-resistant layer;

[0011] Wherein, the interior of the wear-resistant cavity is coated with a wear-resistant coating made of organic polymer material;

[0012] Wherein, a heat insulating layer is thermally pressed and bonded to the upper surface of the waterproof layer;

[0013] Wherein, the outer surfaces of both the front and rear sides of the heat insulation layer are provided with heat insulation cavities;

[0014] Among them, aerogel is installed inside the thermal insulation cavity;

[0015] The outer surfaces of the upper and lower ends of the non-woven fabric layer are both provided with printing.

[0016] Preferably, a heat-resistant layer is bonded to the lower surface of the second wear-resistant layer by thermal compression.

[0017] Preferably, heat-resistant cavities are provided on the front and rear outer surfaces of the heat-resistant layer.

[0018] Preferably, a heat absorbing block is installed inside the heat-resistant cavity;

[0021] Preferably, the core component of the waterproof layer is a waterproof membrane, and the waterproof membrane is made of a polymer material polyethylene (PE).

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) The two-color printed thermal insulation nonwoven fabric achieves thermal insulation through the aerogel inside the thermal insulation cavity opened on the thermal insulation layer. Since the aerogel has the special property of a nano-scale porous structure, its density is extremely low, so its weight is very light, which makes the thermal insulation layer using aerogel have the characteristics of ultra-lightness, thereby reducing the construction load. At the same time, the aerogel can be flexibly constructed and installed through cutting, making the use of aerogel in the thermal insulation layer convenient and quick, thereby improving the construction efficiency.

[0024] (2) The two-color printed heat-insulating non-woven fabric can prevent external moisture from penetrating through the non-woven fabric layer through the waterproof layer, effectively protecting the internal materials from damage by moisture and maintaining the beauty and functionality of the non-woven fabric layer. At the same time, the waterproof layer makes the non-woven fabric layer easier to clean because moisture and stains are not easily absorbed, making the non-woven fabric layer more convenient in daily use and reducing the trouble of maintenance.

[0036] See also Figure 1-5 , the utility model provides a technical solution: a two-color printed heat-insulating non-woven fabric, comprising a non-woven fabric layer 1;

[0037] The lower end of the non-woven fabric layer 1 is connected to the first wear-resistant layer 4 by heat-pressing and bonding, the upper surface of the first wear-resistant layer 4 is connected to the waterproof layer 3 by heat-pressing and bonding, the surface of the waterproof layer 3 is provided with a waterproof cavity 5, the upper end of the non-woven fabric layer 1 is connected to the second wear-resistant layer 12 by heat-pressing and bonding, the inner wall of the waterproof cavity 5 is coated with a waterproof coating of ethylene-vinyl acetate copolymer (EVA) material, the outer surface of the second wear-resistant layer 12 is provided with a wear-resistant cavity 6, the inside of the wear-resistant cavity 6 is coated with a wear-resistant coating of organic polymer material, the upper surface of the waterproof layer 3 is heat-pressed and bonded with a thermal insulation layer 7, the outer surfaces of the front and rear sides of the thermal insulation layer 7 are provided with thermal insulation cavities 9, the inside of the thermal insulation cavity 9 is installed with aerogels, and the upper and lower ends of the non-woven fabric layer 1 are provided with prints 2.

[0038] Among them, the lower surface of the second wear-resistant layer 12 is hot-pressed and bonded with a heat-resistant layer 13, and the front and rear outer surfaces of the heat-resistant layer 13 are both provided with heat-resistant cavities 10, and a heat absorption block 11 is installed inside the heat-resistant cavity 10. The lower end outer surface of the heat-resistant layer 13 is hot-pressed and bonded to the upper end outer surface of the insulation layer 7.

[0039] The first wear-resistant layer 4 is composed of synthetic fibers, and its main function is to provide good wear resistance, tensile strength and durability, and to be able to resist external friction and abrasion.

[0040] Among them, the core component of the waterproof layer is the waterproof membrane, which is usually a polymer material such as polyethylene (PE). The waterproof membrane has good waterproof properties and can effectively block the passage of moisture.

[0041] Among them, common materials for the heat-resistant layer include ceramic fiber, glass fiber, etc. These materials have excellent heat absorption properties, which can effectively reduce the transfer of heat inside the non-woven fabric and improve the high temperature resistance of the non-woven fabric.

The waterproof layer 3 can prevent external moisture from penetrating through the non-woven fabric layer 1, effectively protecting the internal material from moisture damage, and maintaining the beauty and functionality of the non-woven fabric layer 1. At the same time, the waterproof layer 3 makes the non-woven fabric layer 1 easier to clean, because moisture and stains are not easily absorbed, making the non-woven fabric layer 1 more convenient in daily use and reducing the trouble of maintenance.

[0044] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
