Description

Technical Field

[0001] This utility model relates to the field of pearl cotton, and in particular to a heat-resistant and deformation-resistant pearl cotton. Background Technology

[0002] Existing EPE foam has poor heat resistance. When the heat on the EPE foam is too high during use, it is easily damaged, affecting its service life. Existing EPE foam also has poor elastic cushioning performance. When EPE foam is subjected to compression during use, it is easy to deform and difficult to restore its original shape. Therefore, a heat-resistant and deformation-resistant EPE foam is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 In this embodiment of the present invention, a heat-resistant and deformation-resistant pearl cotton includes a first pearl cotton layer 1, a second pearl cotton layer 2, a third pearl cotton layer 3, a fourth pearl cotton layer 4, a fifth pearl cotton layer 5, and a sixth pearl cotton layer 6. The second pearl cotton layer 2 is horizontally attached to the first pearl cotton layer 1, and a second polyimide fiber interlayer 11 is bonded and sandwiched between the second pearl cotton layer 2 and the first pearl cotton layer 1. The upper and lower surfaces of the second polyimide fiber interlayer 11 are respectively parallel to and bonded to the second pearl cotton layer 2 and the first pearl cotton layer 1. The third pearl cotton layer 3 is horizontally attached to the second pearl cotton layer 2, and a second pearl cotton layer 2 is bonded and sandwiched between the third pearl cotton layer 3. The second mono-fatty acid glyceride interlayer 10 is attached to the second pearl cotton layer 2 and the third pearl cotton layer 3 on its upper and lower sides, respectively. Because the second polyimide fiber interlayer 11 is ceramicized and forms ceramicized cotton, the pearl cotton can resist acid and alkali corrosion in high-temperature environments and has excellent tensile strength and heat resistance. The second mono-fatty acid glyceride interlayer 10 contains one lipophilic long-chain alkyl group and two hydrophilic hydroxyl groups, which is an important nonionic surfactant with stabilizing, foaming aid, anti-shrinkage, lubricating, antistatic, modification aid and anti-fogging effects, making the pearl cotton less prone to shrinkage.

[0020] The fourth pearl cotton layer 4 is horizontally attached to the fifth pearl cotton layer 5, and a first mono-fatty acid glyceride interlayer 8 is bonded and sandwiched between the fifth pearl cotton layer 5 and the fourth pearl cotton layer 4. The upper and lower surfaces of the first mono-fatty acid glyceride interlayer 8 are respectively parallel to and attached to the fifth pearl cotton layer 5 and the fourth pearl cotton layer 4. Because the first mono-fatty acid glyceride interlayer 8 contains one lipophilic long-chain alkyl group and two hydrophilic hydroxyl groups, it is an important type of nonionic surfactant with stabilizing, foaming aid, anti-shrinkage, lubricating, antistatic, modification aid and anti-fogging effects, making the pearl cotton less prone to shrinkage.

[0021] The sixth pearl cotton layer 6 is horizontally attached to the fifth pearl cotton layer 5, and a first polyimide fiber interlayer 7 is bonded and sandwiched between the fifth pearl cotton layer 5 and the sixth pearl cotton layer 6. The upper and lower surfaces of the first polyimide fiber interlayer 7 are respectively parallel to and bonded to the fifth pearl cotton layer 5 and the sixth pearl cotton layer 6. Because the first polyimide fiber interlayer 7 has undergone ceramic treatment to form ceramic cotton, the pearl cotton can resist acid and alkali corrosion in high temperature environments and has excellent tensile strength and heat resistance.

[0022] The fourth pearl cotton layer 4 is horizontally attached to the third pearl cotton layer 3, and a hollow fiber interlayer 9 is bonded and sandwiched between the third pearl cotton layer 3 and the fourth pearl cotton layer 4. The upper and lower surfaces of the hollow fiber interlayer 9 are respectively parallel to the third pearl cotton layer 3 and the fourth pearl cotton layer 4. The hollow fiber interlayer 9 is a ball-shaped cotton layer processed by special ball-forming technology. The cotton ball is hollow inside, with a large air permeability space, which makes it warmer and more breathable. Moreover, after the product is quilted, it will automatically expand, making the pearl cotton less prone to deformation.

[0023] The bonding areas between the first pearl cotton layer 1, the second pearl cotton layer 2, the third pearl cotton layer 3, the fourth pearl cotton layer 4, the fifth pearl cotton layer 5, and the sixth pearl cotton layer 6 are all vertically formed with a first connecting protrusion 12 and a second connecting protrusion 13. The first connecting protrusion 12 and the second connecting protrusion 13 are both located on the side of the first pearl cotton layer 1, the second pearl cotton layer 2, the third pearl cotton layer 3, the fourth pearl cotton layer 4, the fifth pearl cotton layer 5, and the sixth pearl cotton layer 6, and the first connecting protrusion 12 and the second connecting protrusion 13 are vertically bonded to each other.
