Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging materials, in particular to a shockproof and buffering pearl cotton. Background Art
[0002] In the field of packaging and transportation, pearl cotton is widely used to protect goods from physical damage because of its light weight and good cushioning performance. Traditional pearl cotton is mainly made of polyethylene plastic, which has a certain elasticity and load-bearing capacity, and can absorb and disperse the impact of the outside world on the packaged items. However, with the diversification of transportation methods and the increase in the variety of goods, the limitations of traditional pearl cotton in shockproof and cushioning performance have gradually emerged. Especially for heavy objects or high-value, fragile products such as electronic equipment, precision instruments, etc., traditional pearl cotton often cannot provide adequate protection.
[0003] Existing pearl cotton products have certain limitations in terms of density, thickness and elasticity. Although higher density pearl cotton enhances the firmness of the material, it correspondingly reduces the softness and cushioning capacity of the material, making it impossible for the material to effectively absorb the impact under extreme conditions, such as high drop height or heavy pressure, resulting in damage to the items in the package.
[0004] In order to solve the above problems, the present application provides a shock-proof and buffering pearl cotton. Utility Model Content
[0005] The purpose of the utility model is to provide a pearl cotton with better shockproof and buffering performance in view of the deficiencies of the prior art.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A shockproof and buffering pearl cotton, comprising a first pearl cotton layer, a second pearl cotton layer and a third pearl cotton layer arranged in sequence from top to bottom, wherein the density ρ1 of the first pearl cotton layer, the density ρ2 of the second pearl cotton layer and the density ρ3 of the third pearl cotton layer satisfy the relationship: ρ1>ρ2>ρ3; and the first pearl cotton layer, the second pearl cotton layer and the third pearl cotton layer are all provided with staggered pore structures;
[0008] Wherein, the density ρ1 of the first pearl cotton layer is 60kg / m 3 ~90kg / m 3 The density of the second pearl cotton layer is ρ2 30kg / m 3 ~50kg / m 3 The density of the third pearl cotton layer is ρ3 10kg / m 3 ~20kg / m 3 .
[0009] In some embodiments according to the present invention, the density ρ1 of the first pearl cotton layer is 80kg / m 3 The density of the second pearl cotton layer is 40kg / m 3 The density of the third pearl cotton layer is 20kg / m 3 .
[0010] In some embodiments according to the utility model, a first sponge sound-absorbing layer is further arranged between the first pearl cotton layer and the second pearl cotton layer, and a second sponge sound-absorbing layer is further arranged between the second pearl cotton layer and the third pearl cotton layer; the first sponge sound-absorbing layer and the second sponge sound-absorbing layer both have a wavy channel structure inside.
[0011] In some embodiments of the present invention, a bamboo charcoal fiber layer is further provided between the first pearl cotton layer and the second pearl cotton layer, and a glass fiber layer is further provided between the second pearl cotton layer and the third pearl cotton layer.
[0012] In some embodiments according to the present invention, the thickness H1 of the first pearl cotton layer, the thickness H2 of the second pearl cotton layer and the thickness H3 of the third pearl cotton layer satisfy the relationship: H1>H2>H3.
[0013] In some embodiments according to the present invention, the thickness H1 of the first pearl cotton layer is 8-10 mm.
[0014] In some embodiments according to the present invention, the thickness H2 of the second pearl cotton layer is 5-7 mm.
[0015] In some embodiments according to the present invention, the thickness H3 of the third pearl cotton layer is 1-4 mm.
[0016] The beneficial effect of the utility model is that the utility model provides a shockproof buffering pearl cotton, comprising a first pearl cotton layer, a second pearl cotton layer and a third pearl cotton layer arranged in sequence from top to bottom, wherein the density ρ1 of the first pearl cotton layer, the density ρ2 of the second pearl cotton layer and the density ρ3 of the third pearl cotton layer satisfy the relationship: ρ1>ρ2>ρ3; and the first pearl cotton layer, the second pearl cotton layer and the third pearl cotton layer are all provided with staggered pore structures; wherein the density ρ1 of the first pearl cotton layer is 60kg / m 3 ~90kg / m 3 The density of the second pearl cotton layer is ρ2 30kg / m 3 ~50kg / m 3 The density of the third pearl cotton layer is ρ3 10kg / m 3 ~20kg / m 3. Compared with the prior art, the utility model can achieve graded buffering by adopting a three-layer pearl cotton structure with different densities (ρ1>ρ2>ρ3), so that the impact force from the outside to the inside can be absorbed and weakened layer by layer. The high-density pearl cotton in the outermost layer provides a solid first-layer protection to prevent external impact from directly acting on sensitive items; the medium-density pearl cotton in the middle layer further absorbs and slows down the impact force; the low-density pearl cotton in the innermost layer is used to cling to the items, provide meticulous protection and minimize micro-vibrations. This design of decreasing density from the outside to the inside makes the pearl cotton show an excellent buffering effect as a whole, which is especially suitable for protecting fragile items such as electronic equipment and precision instruments. In addition, the staggered pore structure of each layer of pearl cotton not only increases the permeability of the material, but also helps to further disperse the impact energy, thereby improving the overall shockproof performance. This structural design ensures that the pearl cotton will not be completely compacted even when it is under greater pressure, thereby maintaining continuous buffering performance. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 This is a schematic diagram of the structure of Example 1 of the present utility model.
[0018] In the figure: 1, the first pearl cotton layer; 2, the second pearl cotton layer; 3, the third pearl cotton layer. DETAILED DESCRIPTION
[0019] In order to make the technical solution and advantages of the utility model clearer, the utility model and its beneficial effects will be further described in detail below in combination with specific implementation methods and drawings of the specification, but the implementation methods of the utility model are not limited thereto.
[0020] Example 1
[0021] like Figure 1 As shown, a shockproof and buffering pearl cotton provided in this embodiment includes a first pearl cotton layer 1, a second pearl cotton layer 2 and a third pearl cotton layer 3 arranged in sequence from top to bottom, and the density ρ1 of the first pearl cotton layer 1, the density ρ2 of the second pearl cotton layer 2 and the density ρ3 of the third pearl cotton layer 3 satisfy the relationship: ρ1>ρ2>ρ3; and the first pearl cotton layer 1, the second pearl cotton layer 2 and the third pearl cotton layer 3 are all provided with an alternating pore structure.
[0022] Wherein, the density ρ1 of the first pearl cotton layer 1 is 60kg / m 3 ~90kg / m 3 The density ρ2 of the second pearl cotton layer 2 is 30kg / m 3 ~50kg / m 3 The density ρ3 of the third pearl cotton layer 3 is 10kg / m 3 ~20kg / m 3The combination within this ratio range can achieve the best shockproof and cushioning effect, improving the overall performance of the pearl cotton.
[0023] In this embodiment, the density ρ1 of the first pearl cotton layer 1 is 80kg / m 3 The density ρ2 of the second pearl cotton layer 2 is 40kg / m 3 The density ρ3 of the third pearl cotton layer 3 is 20kg / m 3 .
[0024] In this embodiment, the layers can be formed into an integrated sheet structure by a heat-pressing bonding or spraying process known in the art.
[0025] The utility model can achieve graded buffering by adopting a three-layer pearl cotton structure with different densities (ρ1>ρ2>ρ3), so that the impact force from the outside to the inside can be absorbed and weakened layer by layer. The high-density pearl cotton of the outermost layer provides a solid first-layer protection to prevent external impact from directly acting on sensitive items; the medium-density pearl cotton of the middle layer further absorbs and slows down the impact force; the low-density pearl cotton of the innermost layer is used to cling to the items, provide meticulous protection and minimize micro-vibrations. This design of decreasing density from the outside to the inside allows the pearl cotton to exhibit an excellent buffering effect as a whole, and is particularly suitable for protecting fragile items such as electronic equipment and precision instruments. In addition, the staggered pore structure of each layer of pearl cotton not only increases the permeability of the material, but also helps to further disperse the impact energy, thereby improving the overall shockproof performance. This structural design ensures that the pearl cotton will not be completely compacted even when subjected to greater pressure, thereby maintaining continuous buffering performance.
[0026] Example 2
[0027] Different from Example 1, a first sponge sound-absorbing layer is further provided between the first pearl cotton layer 1 and the second pearl cotton layer 2, and a second sponge sound-absorbing layer is further provided between the second pearl cotton layer 2 and the third pearl cotton layer 3; the first sponge sound-absorbing layer and the second sponge sound-absorbing layer both have a wavy channel structure inside. By providing a sponge sound-absorbing layer, the built-in wavy channel structure can effectively absorb sound waves and reduce noise, further expanding the application field of pearl cotton.
[0028] The other structures are the same as those in Example 1 and will not be described in detail here.
[0029] Example 3
[0030] Different from Example 1, a bamboo charcoal fiber layer is further provided between the first pearl cotton layer 1 and the second pearl cotton layer 2, and a glass fiber layer is further provided between the second pearl cotton layer 2 and the third pearl cotton layer 3. The addition of the bamboo charcoal fiber layer and the glass fiber layer not only improves the strength and toughness of the pearl cotton, but also effectively improves the fire resistance of the pearl cotton.
[0031] The other structures are the same as those in Example 1 and will not be described in detail here.
[0032] Example 4
[0033] Different from Example 1, the thickness H1 of the first pearl cotton layer 1, the thickness H2 of the second pearl cotton layer 2 and the thickness H3 of the third pearl cotton layer 3 of this embodiment satisfy the relationship: H1>H2>H3; the thickness H1 of the first pearl cotton layer 1 is 8-10mm, preferably 9mm; the thickness H2 of the second pearl cotton layer 2 is 5-7mm, preferably 6mm; the thickness H3 of the third pearl cotton layer 3 is 1-4mm, preferably 3mm. The three-layer pearl cotton design of this embodiment adopts a decreasing thickness (H1>H2>H3) setting. The thicker outer layer can first absorb and disperse the larger external impact force, and the gradually thinning design of the middle layer and the inner layer is convenient for more fitting protection of the items in the package, while maintaining sufficient flexibility to adapt to items of different shapes.
[0034] The other structures are the same as those in Example 1 and will not be described in detail here.
[0035] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
