Description

Technical Field

[0001] The utility model relates to a PVC sheet material, in particular to a PVC sheet material suitable for preparing a box body. Background Art

[0002] At present, for the preparation of boxes used for storing objects or electronics, PC materials are mainly used for processing through the blister forming method.

[0003] However, such boxes are prone to breakage due to abnormal deformation after encountering stress impact, which reduces the service life. At the same time, after stacking objects, they will also be abnormally deformed due to pressure and cannot protect the internal objects. In addition, directly using PC material is often not suitable for storing food and is not suitable for the transportation and storage of fruits and vegetables.

[0004] At present, composite sheets are also used in cabinet manufacturing. However, such sheets do not provide good support for the cabinet, and have poor external wear resistance, which easily leaves a large number of scratches. Therefore, the appearance is poor. In addition, if traditional PVC sheets are used for cabinet preparation, large pieces will still break when subjected to stress impact.

[0005] In view of the above-mentioned defects, the designers actively carried out research and innovation in order to create a PVC sheet suitable for box preparation, making it more valuable for industrial use. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a PVC sheet suitable for box preparation.

[0011] Furthermore, in the above-mentioned PVC sheet suitable for preparing a box, the thickness of the PC layer is 1.5 mm.

[0012] Furthermore, in the above-mentioned PVC sheet suitable for preparing a box, the inner lining layer is a PET layer, and the thickness of the PET layer is 0.2 to 1.5 mm.

[0013] Furthermore, in the above-mentioned PVC sheet suitable for preparing a box, the thickness of the PET layer is 1 mm.

[0014] Furthermore, in the above-mentioned PVC sheet suitable for preparing a box, the thickness of the glass fiber layer is 0.5 to 2.5 mm.

[0015] Furthermore, in the above-mentioned PVC sheet suitable for preparing a box, the thickness of the glass fiber layer is 2 mm.

[0016] Furthermore, in the above-mentioned PVC sheet suitable for preparing a box, an epoxy resin edging layer is distributed on the outer sides of the PVC supporting layer, the protective layer, the lining layer, the glass fiber layer, and the non-woven fabric sandwiching layer.

[0029] 7 Receiving groove 8 Epoxy resin edging layer DETAILED DESCRIPTION

[0030] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] like Figures 1 to 2 The PVC sheet used for the preparation of the box includes a PVC support layer 1, which has an appropriate anti-deformation auxiliary support effect and realizes auxiliary positioning for the distribution of subsequent layers. The difference is that: a protective layer 2 is distributed on the PVC support layer 1 to reduce the surface scratches. During use, the protective layer 2 can be sprayed with paint or attached with decorative paper according to the decoration needs of the box. At the same time, a composite reinforcement layer 3 is distributed under the PVC support layer 1 to provide appropriate support, so that the finished sheet has better rigidity in a proper shape state, which is convenient for carrying and daily stacking of corresponding items as a box. In addition, an inner lining layer 4 is distributed under the composite reinforcement layer 3, so that after the box is made, it has a better internal environment cleanliness and is easy to clean. During implementation, in order to have a better support effect and reduce excessive accumulation of dead weight, the composite reinforcement layer 3 used in the utility model includes a glass fiber layer 5, and non-woven fabric clamping layers 6 are distributed on both the upper and lower surfaces of the glass fiber layer 5. In this way, during the preparation, the shaping and fixing of the glass fiber layer 5 itself can be achieved, and after the finished product is formed, the glass fiber fragments will not fall due to external force. Furthermore, considering the need for integration, the PVC support layer 1, the protective layer 2, the lining layer 4, the glass fiber layer 5, and the non-woven fabric sandwich layer 6 are provided with adhesive layers. The adhesive layer can be made of a conventional commercially available solidifying colloid. During the preparation, other processing methods can also be used, as long as the final PVC sheet has better integrity, which will not be repeated here.

[0032] In combination with a preferred embodiment of the utility model, the thickness of the PVC support layer 1 is 0.2 to 3 mm, and a plurality of receiving grooves 7 are distributed on the PVC support layer 1. Appropriate curing colloid can be accommodated through the receiving grooves 7 to facilitate the best bonding with the protective layer 2 during processing. During implementation, the thickness of the PVC support layer 1 is 1.2 mm, the receiving grooves 7 are strip-shaped structures, and the depth of the receiving grooves 7 is 0.2 mm, which can achieve a better effect.

[0033] Further, the protective layer 2 used in the present invention is a PC layer, and the thickness of the PC layer is 0.5 to 2 mm. It has a moderate scratch resistance effect and can be attached to the paint surface, and can be decorated differently according to user needs. During conventional preparation, the thickness of the PC layer is 1.5 mm, which can meet the surface protection needs of various conventional boxes.

[0034] In combination with actual implementation, the inner lining layer 4 is a PET layer, and the thickness of the PET layer is 0.2 to 1.5 mm. During preparation, it can be preferably 1 mm. In this way, relying on the characteristics of the PET layer, it is easy to clean the box, and it can also meet the storage of various foods, so that the box body can have multiple functions of a storage box or a food box, and improve the scope of application.

[0035] Furthermore, in order to achieve a better shaping effect, the thickness of the glass fiber layer 5 is 0.5 to 2.5 mm. If it is a box of regular size, under the condition of daily stacking and storage, the thickness of the glass fiber layer 5 is 2 mm, which can meet the normal load-bearing and anti-deformation effect. In addition, when subjected to a large stress impact, it is transmitted and dissipated through the glass fiber layer, avoiding cracking due to concentrated force, which can effectively extend the service life.

[0036] At the same time, in order to achieve appropriate side "packaging", the utility model has an epoxy resin edging layer 8 distributed on the outside of the PVC support layer 1, the protective layer 2, the lining layer 4, the glass fiber layer 5, and the non-woven fabric sandwich layer 6. In other words, an additional epoxy resin edging layer 8 is distributed on the outer edge of the finished product of the PVC sheet to strengthen the bonding between the layers.

[0037] Of course, during the manufacturing process, the actual thicknesses of the PVC support layer 1, the protective layer 2, the lining layer 4, the glass fiber layer 5, and the non-woven fabric sandwich layer 6 can be adjusted differently as required, which will not be described in detail here.

[0038] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

[0039] 1. As the main bearing body, the PVC support layer can cooperate with the composite reinforcement layer to avoid unnecessary bending and curling of the finished product after the box is prepared, and will not cause abnormal deformation due to pressure during daily stacking.

[0040] 2. It is equipped with a protective layer, which is prepared into a box and faces outwards, has a proper scratch resistance effect, and is also convenient for the adhesion of paint or finishing.

[0041] 3. It is equipped with an independent lining layer, which is convenient for cleaning inside the box and meets the needs of storing some foods, thus improving the use of the box.

[0042] 4. The overall structure is simple and can also be used for the preparation of conventional storage boxes.

[0043] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
