Description

Technical Field

[0001] The utility model relates to the technical field of foam materials, in particular to a non-slip composite foam material. Background Art

[0002] Foam is a porous, soft and light material, commonly used in packaging, heat insulation, sound insulation and shock absorption. It is usually made of plastic materials such as polyester and polyether. These plastics usually show good air permeability and flexibility, and are easy to process with low cost. Through different chemical treatment processes, they have excellent shock absorption performance, shock resistance, sound insulation effect and heat preservation performance. Foam is commonly used in many fields such as packaging, heat insulation, sound insulation, filtration and filling, and has a wide range of applications in industries such as automobiles, electronic devices, home decoration, and sports goods. At the same time, foam is a recyclable material, which is beneficial to environmental protection.

[0003] Due to the wide application range of foam materials, their usage scenarios are all-inclusive and various stress situations will occur. When it is used for packaging, it needs to play a protective role to prevent the internal objects from being damaged. However, when the ordinary foam material is locally stressed, due to the small force sharing area, it may be severely deformed or torn, resulting in the failure of the protective effect. When it is used for shock absorption or filling, it will inevitably be frequently squeezed. After the ordinary foam material is locally compressed and deformed for a long time, it is easy to be unable to return to its original state, resulting in difficulty in continuing to play its role. Therefore, in view of the above problems, a non-slip composite foam is proposed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a non-slip composite foam. A grid strengthening inner core bonded into one body is arranged inside the foam. When the foam is locally stressed, the grid strengthening inner core can drive a larger stress area, avoiding severe deformation or being torn due to the small sharing area when the foam is locally stressed. At the same time, an air inflation strip is arranged inside the foam, which can assist the foam to share the pressure and apply an external thrust after the external force is removed, avoiding the situation that the foam is locally compressed and deformed for a long time and cannot return to its original state, and solving the technical problems that the foam material in the prior art is prone to severe deformation or being torn when locally pulled in a small range, and is prone to being unable to return to its original state after being compressed and deformed for a long time.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is as follows:

[0006] A non-slip composite foam includes an upper foam material base layer and a lower foam material base layer. Embedded grooves are formed on the inner sides of the above two layers. At the same time, insertion filling grooves are opened in the middle of both of them. A grid strengthening inner core is embedded in the embedded grooves and is bonded into one body with the upper foam material base layer and the lower foam material base layer through a colloid. An air inflation strip is inserted in the insertion filling grooves.

[0007] Through the above structural form, the grid reinforcement inner core, which is set to be bonded to the upper foam material base layer and the lower foam material base layer into one body, plays a role in strengthening the tensile performance. When the foam is locally stressed, the grid reinforcement inner core drives a larger stressed area, avoiding serious deformation or being torn due to the relatively small sharing area when the foam is locally stressed. At the same time, an inflatable strip is inserted into the insertion groove in the foam. The inflatable strip can assist the foam in sharing the pressure and applying an external thrust after the external force is removed, avoiding serious deformation of the surface of the foam due to long-term local compression and being unable to return to its original state.

[0008] In a possible implementation manner, the grid reinforcement inner core is woven by longitudinal reinforcement bands and transverse reinforcement bands, and the included angle between each longitudinal reinforcement band and transverse reinforcement band is a right angle.

[0009] Through the above structural form, the tensile performance of the foam in the transverse and longitudinal directions can be enhanced by the longitudinal reinforcement bands and transverse reinforcement bands that are perpendicular to each other, so that when using the foam, there is no need to consider the setting direction problem, and it can be edited more freely.

[0010] In a possible implementation manner, the cross-sectional forms of the longitudinal reinforcement band and the transverse reinforcement band are rounded rectangles and their cross-sectional dimensions are the same. The cross-sectional form of the groove body of the embedding groove is a half-rounded rectangle, and the dimensions are consistent with those of the longitudinal reinforcement band and the transverse reinforcement band.

[0011] Through the above structural form, the longitudinal reinforcement band, the transverse reinforcement band and the embedding groove can be made to fit, and then after bonding the upper foam material base layer, the lower foam material base layer and the grid reinforcement inner core with colloid, the integrity is stronger. And the cross-sectional form of the rounded rectangle can increase the bonding area, making the bonding among the upper foam material base layer, the lower foam material base layer and the grid reinforcement inner core more firm.

[0012] In a possible implementation manner, the inflatable strip includes a protective outer sleeve, a strip-shaped airbag is arranged inside the protective outer sleeve, and compressed gas is filled in the strip-shaped airbag.

[0013] Through the above structural form, the protective outer sleeve can protect the strip-shaped airbag, and can also help the strip-shaped airbag share the air pressure, avoiding the bursting of the strip-shaped airbag due to being unable to bear the air pressure when being compressed. And the strip-shaped airbag can apply an external thrust to the protective outer sleeve, enabling it to return to its original state when the external force is removed, and then pushing the surface of the foam to return to its original state.

[0014] In a possible implementation manner, the outer cross-sectional dimensions of the protective outer sleeve are the same as the cross-sectional dimensions of the groove body of the insertion groove, and the cross-sectional forms of the above two are both rounded rectangles.

[0015] Through the above structural form, the insertion groove can play a role in restraining and fixing the inflatable strip, thereby ensuring the normal use of the foam.

[0016] In a possible implementation, the protective jacket is made of wear-resistant rubber, and two air release grooves are provided on both the upper and lower end faces thereof, and the air release grooves are arranged along the length direction of the protective jacket.

[0017] With the above structural form, when the inflatable strip is inserted into the insertion groove during the production process, the air in the insertion groove can be discharged through the air release groove, avoiding the air pressure from hindering the insertion of the inflatable strip.

[0018] In a possible implementation, anti-slip grooves are provided on both the upper end face of the upper foam material base layer and the lower end face of the lower foam material base layer, and the overall trend of the anti-slip grooves is wavy.

[0019] With the above structural form, the provided anti-slip grooves can improve the anti-slip performance of the foam surface, and the wavy anti-slip grooves can also improve the aesthetics of the foam surface.

[0020] In summary, the utility model includes the following beneficial technical effects:

[0021] The grid reinforcement inner core provided and bonded to the upper foam material base layer and the lower foam material base layer plays a role in strengthening the tensile performance. When the foam is locally stressed, the grid reinforcement inner core can drive a larger stressed area, avoiding serious deformation or being torn due to the small sharing area when the foam is locally stressed; at the same time, an inflatable strip is inserted into the insertion groove in the foam, and the inflatable strip can assist the foam in sharing the pressure and apply an external thrust after the external force is removed, avoiding the surface of the foam being seriously deformed and unable to return to its original state due to long-term local compression.

Detailed implementation mode

[0028] The technical solution in the embodiment of the present application is to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0029] As Figure 1 - Figure 2 shown, a non-slip composite foam provided in this embodiment includes an upper foam material base layer 11 and a lower foam material base layer 12. Embedding grooves 101 are processed on the inner sides of the above two, and inserting and filling grooves 102 are opened in the middle of both. A grid reinforcement inner core 2 is embedded in the embedding groove 101 and is bonded to the upper foam material base layer 11 and the lower foam material base layer 12 into one body through a colloid. An inflatable strip 3 is inserted into the inserting and filling groove 102. Through the above structural form, the grid reinforcement inner core 2 bonded to the upper foam material base layer 11 and the lower foam material base layer 12 is used to enhance the tensile performance. When the foam is locally stressed, a larger stressed area is pulled by the grid reinforcement inner core 2, avoiding serious deformation or being torn due to the small sharing area when the foam is locally stressed. At the same time, an inflatable strip 3 is inserted into the inserting and filling groove 102 in the foam. The inflatable strip 3 can assist the foam in sharing the pressure and apply an external thrust after the external force is removed, avoiding serious deformation of the surface of the foam due to long-term local pressure and being unable to return to its original state.

[0030] As Figure 4 shown, the grid reinforcement inner core 2 is woven by longitudinal reinforcement belts 21 and transverse reinforcement belts 22, and the included angle between each longitudinal reinforcement belt 21 and transverse reinforcement belt 22 is a right angle. Through the above structural form, the tensile performance of the foam in the transverse and longitudinal directions can be enhanced by the longitudinal reinforcement belts 21 and transverse reinforcement belts 22 perpendicular to each other, so that when using the foam, there is no need to consider the setting direction problem, and it can be edited more freely.

[0031] In addition, the cross-sectional forms of the longitudinal reinforcement belt 21 and the transverse reinforcement belt 22 are rounded rectangles and their cross-sectional dimensions are the same. The cross-sectional form of the groove body of the embedding groove 101 is a half-rounded rectangle and its size matches the sizes of the longitudinal reinforcement belt 21 and the transverse reinforcement belt 22. Through the above structural form, the longitudinal reinforcement belt 21, the transverse reinforcement belt 22 and the embedding groove 101 can fit, and then after bonding the upper foam material base layer 11, the lower foam material base layer 12 and the grid reinforcement inner core 2 with a colloid, the integrity is stronger. And the cross-sectional form of the rounded rectangle can increase the bonding area, making the bonding between the upper foam material base layer 11, the lower foam material base layer 12 and the grid reinforcement inner core 2 more firm.

[0032] As shown Figure 3 in the figure, the inflatable strip 3 includes a protective jacket 31. Inside the protective jacket 31, there is a strip-shaped airbag 32 filled with compressed gas. The protective jacket 31 can protect the strip-shaped airbag 32 and also help the strip-shaped airbag 32 share the air pressure, preventing the strip-shaped airbag 32 from bursting due to excessive air pressure when being pressed. The strip-shaped airbag 32 can exert an external thrust on the protective jacket 31, enabling it to return to its original shape when the external force is removed, and then pushing the surface of the foam back to its original shape. In addition, the outer cross-sectional dimension of the protective jacket 31 is the same as the cross-sectional dimension of the slot body of the insertion slot 102, and the cross-sectional shapes of both are rounded rectangles. The insertion slot 102 can constrain and fix the inflatable strip 3, thus ensuring the normal use of the foam.

[0033] As shown Figure 3 in the figure, the protective jacket 31 is made of wear-resistant rubber, and two air release grooves 33 are provided on both the upper and lower end faces. The air release grooves 33 are arranged along the length direction of the protective jacket 31. With this structural form, when inserting the inflatable strip 3 into the insertion slot 102 during the production process, the air in the insertion slot 102 can be discharged through the air release grooves 33, preventing air pressure from hindering the insertion of the inflatable strip 3.

[0034] As shown Figure 1 in the figure, anti-slip grooves 103 are provided on both the upper end face of the upper foam material base layer 11 and the lower end face of the lower foam material base layer 12. The overall trend of the anti-slip grooves 103 is wavy. With this structural form, the provided anti-slip grooves 103 can improve the anti-slip performance of the foam surface, and the wavy anti-slip grooves 103 can also improve the aesthetic property of the foam surface.

[0035] The working principle and process of the present utility model:

[0036] The grid strengthening inner core 2 bonded to the upper foam material base layer 11 and the lower foam material base layer 12 can enhance the tensile strength. When the foam is locally stressed, the grid strengthening inner core 2 can pull a larger stressed area, and at the same time, the longitudinal strengthening bands 21 and the transverse strengthening bands 22 constituting the grid strengthening inner core 2 will also jointly participate in the stress, thus avoiding the situation that the foam is severely deformed or torn due to the too small sharing area when locally stressed and cannot be used continuously.

[0037] Meanwhile, an inflatable strip 3 is inserted into the insertion slot 102 in the foam. The inflatable strip 3 can assist the foam in sharing the pressure and exert an external thrust after the external force is removed, preventing the surface of the foam from being severely deformed and unable to return to its original shape due to long-term local pressure.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
