[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The embodiments of the present application provide a cushioning packaging structure, which can solve the problem in the related art that the cushioning packaging material part has insufficient cushioning packaging performance and thus cannot meet actual use requirements.

[0026] like Figure 1 As shown, the cushioning packaging structure of this embodiment includes an aerogel body 1 and a reinforcement structure. The reinforcement structure is arranged in the aerogel body 1.

[0027] Preferably, the reinforcement structure is at least one layer of hollow tube group, at least one layer of fiberboard, at least one layer of gauze 3, or multiple layers of corrugated paper 4.

[0028] In this embodiment, by arranging a reinforcement structure in the aerogel body, and the reinforcement structure is at least one layer of hollow tube group, at least one layer of fiberboard, at least one layer of gauze, or multiple layers of corrugated paper, not only can the partial cushioning packaging performance of the cushioning packaging structure be improved, but also through the characteristics of light weight and large volume of the internal reinforcement structure, the material used in the aerogel body can be reduced, so as to reduce the weight and cost of the cushioning packaging structure under the same volume and meet actual use requirements.

[0029] On the basis of the above-mentioned embodiment, in this embodiment, each layer of hollow tube group includes a plurality of hollow tubes 2, and the above-mentioned hollow tubes 2 are hollow tubes with certain elasticity.

[0030] like Figure 1 and Figure 2 As shown, optionally, the reinforcement structure is a layer of hollow tube groups, and a plurality of hollow tubes 2 in the layer of hollow tube groups are arranged in parallel in sequence, and every two adjacent hollow tubes 2 are in non-pressure contact.

[0031] Optionally, the reinforcement structure is a multi-layer hollow tube group, and the multiple hollow tubes 2 in each layer of the hollow tube group are arranged in parallel and in sequence without pressure contact, and the hollow tubes 2 in every two adjacent layers of the hollow tube group are not in contact.

[0032] In this embodiment, the number of hollow tube groups can be determined according to the thickness and performance requirements of the final cushioning packaging material.

[0033] In some embodiments, the hollow tubes 2 of each two adjacent layers of hollow tube groups are staggered, that is, the central axes of any two hollow tubes 2 located in two adjacent layers above and below are not in the same vertical plane.

[0034] In some embodiments, the hollow tubes 2 of each two adjacent layers of hollow tube groups are arranged perpendicular to each other.

[0035] Optionally, both ends of the hollow tube 2 are sealed, and fillers may be provided inside the hollow tube 2 .

[0036] Furthermore, the hollow tube 2 is filled with aerogel powder or lightweight foam powder.

[0037] In this embodiment, by filling the hollow tube 2 with aerogel powder made from natural polysaccharides or powder made from other lightweight foams, the toughness of the cushioning packaging structure can be further increased.

[0038] Optionally, the filler may be waste paper scraps, waste wood scraps, chopped straw, etc. in addition to aerogel powder or lightweight foam powder.

[0039] In this embodiment, by adjusting the type of filler in the hollow tube 2, different elasticity and support can be given to the hollow tube 2. When external force acts on the cushioning packaging structure, the external force is transmitted to the hollow tube 2 by the biomass aerogel on the surface. Since the hollow tube 2 itself has good resilience, when the external force is removed, the material can return to its original state as much as possible, thereby making the cushioning packaging structure in which the hollow tube 2 is embedded have different elasticity and support. The composite use of aerogel and hollow tube 2 effectively overcomes the problem that elasticity and hardness cannot be taken into account when hollow tube 2 or biomass material is used alone.

[0040] Furthermore, the hollow tube 2 is a paper tube, and the radial cross-section of the paper tube is circular, square or irregular.

[0041] Optionally, the hollow tube 2 is a round tube made of a degradable material.

[0042] Preferably, the diameter of the hollow tube 2 is 4 mm to 20 mm, and the hollow tube 2 is made of a three-layer spiral paper tube. The spiral paper tube has excellent structural strength and can better withstand radial or lateral pressure and tension. The ratio of the gram weight to the diameter of the hollow tube 2 is (15-30): 1. The larger the diameter of the hollow tube 2, the higher the corresponding gram weight, thereby increasing the strength and toughness of the paper tube. Among them, the gram weight of the hollow tube 2 refers to the weight per unit area of ​​the base paper rolled into the spiral paper tube. Optionally, the mass per unit length of the hollow tube 2 is 0.04-0.12g / cm.

[0043] In this embodiment, the aerogel body and the paper tube material are environmentally friendly and degradable. By burying the paper tube in the biomass aerogel, not only can the environmental protection problem of the packaging cushioning material be solved, but also the problem of insufficient cushioning and supporting strength of the packaging cushioning structure can be effectively solved according to the different materials of the filler in the paper tube.

[0044] On the basis of the above embodiment, in this embodiment, when the above reinforcement structure is a multi-layer corrugated paper layer 4, the corrugation directions of every two adjacent layers of corrugated paper layers 4 are perpendicular to each other.

[0045] Optionally, the corrugation directions of two adjacent corrugated paper layers 4 are parallel, and the crest of the upper corrugated paper layer 4 is opposite to the trough of the lower corrugated paper layer 4, so as to increase the elasticity and toughness of the cushioning packaging structure.

[0046] Optionally, in the upper and lower corrugated paper layers 4, vertical paper tubes are arranged between the relative crests and troughs, and the upper and lower edges of the paper tubes are respectively bonded to the crests and troughs to prevent the paper tubes from collapsing, and multiple paper tubes are arranged at intervals on each crest.

[0047] In this embodiment, by providing a paper tube, the compressive strength of the cushioning packaging structure can be further enhanced.

[0048] Preferably, the multi-layer corrugated paper layer 4 is at least three layers. In this embodiment, by filling the corrugated paper layer in the aerogel body, the weight of the cushioning packaging structure can be reduced, the toughness of the cushioning packaging material can be enhanced, and the freeze-drying time in the production process can be reduced, saving costs.

[0049] On the basis of the above-mentioned embodiment, in this embodiment, when the above-mentioned reinforcement structure is at least one layer of fiberboard, the above-mentioned fiberboard is a porous fiberboard.

[0050] Preferably, the fiberboard is a corrugated porous fiberboard.

[0051] Optionally, the corrugated porous fluffy fiberboard can be made by crushing wheat straw, rice straw and corn into mixed powder of 1 to 10 mm by a crusher, and then bonding the mixed powder by an adhesive. The material for preparing the adhesive includes one or more of polyvinyl alcohol, carboxymethyl cellulose and pullulan, and the concentration of the adhesive is 2 to 10%.

[0052] In this embodiment, by arranging the corrugated porous fiberboard in the aerogel body, the elasticity and toughness of the cushioning packaging structure can be effectively increased.

[0053] On the basis of the above embodiment, in this embodiment, when the above-mentioned reinforcement structure is at least one layer of gauze 3, the above-mentioned gauze 3 is cotton yarn with a mesh structure, the mesh number of the above-mentioned gauze 3 is 10-120 meshes, and the thickness is 0.2-2mm, so as to effectively increase the toughness of the cushioning packaging structure.

[0054] like Figure 3 and Figure 4 As shown, in this embodiment, the above-mentioned reinforcement structure is two layers of gauze 3.

[0055] Optionally, the transverse dimensions of the fiberboard, the gauze 3 and the corrugated paper layer 4 may be smaller than the transverse dimension of the aerogel body, or may be the same as the transverse dimension of the aerogel body.

[0056] Optionally, the aerogel body 1 comprises, by weight: 2-10 parts of starch; 2-10 parts of fiber; 2-20 parts of plasticizer; 1-5 parts of preservative; and 0.5-3 parts of thickener.

[0057] Taking the reinforcement structure as a layer of hollow tube group as an example, the preparation method of the above-mentioned cushioning packaging structure includes the following steps:

[0058] Step 1, taking 2-10 parts of fiber by weight and dispersing them in water, taking 2-10 parts of starch, 2-20 parts of plasticizer, 1-5 parts of preservative, and 0.5-3 parts of thickener, sequentially adding them into water, stirring and dispersing at room temperature, then heating to a preset temperature while stirring, continuing stirring, and then cooling to obtain a colloidal liquid;

[0059] Step 2, pour a layer of gel liquid into the mold and scrape it flat to obtain a first gel liquid layer with a thickness of 3-5mm, then lay a row of hollow tubes on the flattened gel liquid surface, then pour gel liquid again and scrape it flat to form a composite layer. At this time, the thickness of the composite layer is 3-5mm larger than the diameter of the hollow tube, that is, the distance between the upper surface of the gel liquid and the hollow tube is 3-5mm;

[0060] Step 3: sequentially transferring the above mold to a cold storage room for low-temperature cooling, a freezer room for freezing, and a vacuum freezer chamber for vacuum freeze drying to obtain the above buffer packaging structure.

[0061] In this embodiment, the viscosity of the colloid liquid is configured so that when the reinforcing structure is supported, the reinforcing structure will not sink or settle.

[0062] Taking the reinforcement structure as a multi-layer hollow tube group as an example, the preparation method of the above-mentioned cushioning packaging structure includes the following steps:

[0063] Step 1, taking 2-10 parts of fiber by weight and dispersing them in water, taking 2-10 parts of starch, 2-20 parts of plasticizer, 1-5 parts of preservative, and 0.5-3 parts of thickener, sequentially adding them into water, stirring and dispersing at room temperature, then heating to a preset temperature while stirring, continuing stirring, and then cooling to obtain a colloidal liquid;

[0064] Step 2, pour a layer of colloid liquid into the mold and scrape it flat to obtain a first colloid liquid layer with a thickness of 3-5mm, then lay the first row of hollow tubes on the scraped surface of the colloid liquid, and then pour the colloid liquid and scrape it flat to form a first composite layer. At this time, the thickness of the first composite layer is 3-5mm larger than the diameter of the hollow tube, that is, the distance between the upper surface of the colloid liquid and the first row of hollow tubes is 3-5mm;

[0065] Step 3: Lay another row of parallel hollow tubes on the surface of the first composite layer, pour the colloid liquid into it and scrape it flat to form a second composite layer. And so on, more composite layers can be obtained;

[0066] Step 4: sequentially transferring the above mold to a cold storage room for low-temperature cooling, a freezer room for freezing, and a vacuum freezer chamber for vacuum freeze drying to obtain the above buffer packaging structure.

[0067] like Figure 5 As shown, taking the reinforcement structure as three layers of corrugated paper as an example, the preparation method of the above-mentioned cushioning packaging structure includes the following steps:

[0068] Step 1, taking 2-10 parts of fiber by weight and dispersing them in water, taking 2-10 parts of starch, 2-20 parts of plasticizer, 1-5 parts of preservative, and 0.5-3 parts of thickener, sequentially adding them into water, stirring and dispersing at room temperature, then heating to a preset temperature while stirring, continuing stirring, and then cooling to obtain a colloidal liquid;

[0069] Step 2, pour a layer of colloidal liquid into the mold and scrape it flat to obtain a first colloidal liquid layer with a thickness of 3-5 mm, then lay the first corrugated paper layer on the scraped surface of the colloidal liquid, and then pour the colloidal liquid and scrape it flat to form a first composite layer, wherein the colloidal liquid can flow and completely fill the gap between the corrugated paper layer and the first colloidal liquid layer, and the thickness of the first composite layer is 3-5 mm greater than the vertical thickness of the corrugated paper layer, that is, the vertical distance between the upper surface of the colloidal liquid and the first corrugated paper layer is 3-5 mm; wherein the vertical thickness of the corrugated paper layer is the distance between the crest and the trough in the vertical direction.

[0070] Step 3: After laying the second corrugated paper layer on the surface of the first composite layer, pour the colloid liquid and scrape it flat to form a second composite layer, wherein the thickness of the second composite layer is 3-5 mm greater than the vertical thickness of the corrugated paper layer.

[0071] Step 4: After laying the third corrugated paper layer on the surface of the second composite layer, pour the colloid liquid and scrape it flat to form a third composite layer, wherein the thickness of the third composite layer is 3-5 mm greater than the vertical thickness of the corrugated paper layer.

[0072] Step 5: sequentially transfer the above mold to a cold storage room for low-temperature cooling, a freezer room for freezing, and a vacuum freezer chamber for vacuum freeze drying to obtain the above buffer packaging structure.

[0073] In this embodiment, the above-mentioned biomass aerogel body is prepared in sequence by low-temperature cooling, freezing and vacuum freeze-drying, and the pores left by ice crystal sublimation are used to obtain a honeycomb pore structure. Not only is the pore making method controllable, but the biomass aerogel itself also has a certain compressive strength and elasticity; at the same time, the reinforcing structure is pre-buried in the biomass aerogel, which can reduce the cost of the aerogel material, and at the same time, the elasticity and support of the reinforced structure are utilized to magnify the advantages of the overall compressive strength, elasticity and toughness of the material.

[0074] Furthermore, the stirring frequency of the above-mentioned normal temperature stirring is 30Hz; the above-mentioned preset temperature is 85-95°C; during the above-mentioned continuous stirring treatment, the stirring frequency is 50Hz, and the continuous stirring time is at least 40min. During the above-mentioned cooling, the temperature of the obtained colloid liquid is not higher than 40°C through coil cooling, and the viscosity of the above-mentioned colloid liquid is 45500-60500mpa.s.

[0075] Furthermore, when transferred to the cold storage room for low-temperature cooling, the cooling temperature is 1-10°C, and the cooling time is 2-4h; when transferred to the freezer for freezing, the freezing temperature is -20 to -40°C, and the freezing time is 2-4h; when transferred to the vacuum freezing chamber for vacuum freeze drying, the radiation plate temperature is gradually increased from 20°C to 80°C, the cold trap temperature is -30°C, the vacuum degree is below 30Pa, and the drying time is 12-24h.
