Technical Field

[0001] This utility model relates to the field of release paper technology, specifically a heat-resistant release paper. Background Technology

[0002] Release paper, with its silicone oil layer, possesses a certain degree of heat resistance, making it suitable for microwave heating and storing food. However, existing release papers cannot be bonded to aluminum foil to form a more heat-resistant composite release paper structure, preventing the simultaneous use of these two heat-resistant materials. Extensive research has been conducted to overcome this technical challenge of utilizing aluminum foil to improve the heat resistance of release paper. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heat-resistant release paper that can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A heat-resistant release paper of this utility model includes a base paper layer, characterized in that a first tin foil layer is provided on the lower side of the base paper layer, tin foil flanges are provided on both sides of the first tin foil layer, a second tin foil layer is provided on one side of the tin foil flanges, a paper layer located in the middle is provided on the upper side of the base paper layer, the middle paper layer, the second tin foil layer, the first tin foil layer and the first tin foil layer are fixedly connected with the base paper layer, and a silicone oil layer is provided on the top of the second tin foil layer and the middle paper layer.

[0005] In a further technical solution, the second tin foil layer abuts against the top surface of the original paper layer.

[0006] In a further technical solution, the foil flange abuts against the side edge of the original paper layer.

[0007] In a further technical solution, the original paper layer is provided with multiple internal holes, and the diameter of the multiple internal holes distributed from the center to both sides increases sequentially.

[0008] A further technical solution is that an adhesive layer is provided on the upper left and right sides and the lower end face of the original paper layer. After the adhesive layer overflows from the inner hole, it is bonded and fixed to the paper layer located in the middle. The adhesive layer is bonded and fixed to the first tin foil layer, the tin foil flange and the second tin foil layer.

[0009] In a further technical solution, an adhesive edge is fixedly provided at the junction of the second tin foil layer and the paper layer located in the middle.

[0010] The beneficial effects of this utility model are: First, by forming a composite structure consisting of a silicone oil layer, a paper layer in the middle, a second tin foil layer, a tin foil edge, a first tin foil layer, and the original paper layer, the connection and fixation between them are strong, and the heat resistance can be effectively increased. Furthermore, the tin foil layer can maintain the shape of the paper layer, giving the paper layer a certain shape retention ability and preventing deformation after heating.

[0011] Second, the first foil layer is provided with a foil fold and a second foil layer, which can effectively protect the edge and bottom surface of the original paper layer. Furthermore, the layout of the inner hole enhances the strength of the adhesive layer in connecting the original paper layer, the first foil layer, the foil fold, and the second foil layer.

[0012] Third, after the second foil layer, the adhesive edge, and the middle paper layer are flattened, a silicone oil layer is set to improve the flatness of the silicone oil layer, and the first foil layer is directly attached to the lower end surface of the original paper layer to keep the upper and lower end surfaces of the composite paper flat.

[0013] Fourth, setting the middle paper layer to be bonded and fixed to the original paper layer, and applying a silicone oil layer to one side of the middle paper layer can improve the bonding and fixing effect between the silicone oil layer and the middle paper layer. Attached Figure Description

[0014] For ease of explanation, the present invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0017] Figure 3 for Figure 1 A top view of the second foil layer, the adhesive edge, and the paper layer in the middle;

[0018] In the figure, there are adhesive layer 11, inner hole 12, base paper layer 13, first tin foil layer 14, tin foil flange 15, second tin foil layer 16, adhesive edge 17, paper layer 18, and silicone oil layer 19. Detailed Implementation

[0019] like Figures 1-3 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1The projection relationship of this utility model is consistent in the up, down, left, right, front and back directions. The heat-resistant release paper includes a base paper layer 13, a plurality of internal holes 12 are provided in the base paper layer 13, a first tin foil layer 14 is provided on the lower side of the base paper layer 13, tin foil flanges 15 are provided on both sides of the first tin foil layer 14, a second tin foil layer 16 is provided on one side of the tin foil flange 15, the tin foil flange 15 abuts against the side of the base paper layer 13, the second tin foil layer 16 abuts against the top surface of the base paper layer 13, a paper layer 18 is provided on the upper side of the base paper layer 13, the paper layer 18, the second tin foil layer 16, the first tin foil layer 14 and the first tin foil layer 14 are fixedly connected to the base paper layer 13, and a silicone oil layer 19 is provided on the top of the second tin foil layer 16 and the paper layer 18.

[0020] Advantageously, the diameters of the multiple inner holes 12 distributed from the center to both sides increase sequentially.

[0021] Advantageously, adhesive layers 11 are provided on the upper left, right and lower ends of the original paper layer 13. After overflowing from the inner hole 12, the adhesive layer 11 is bonded and fixed to the paper layer 18 located in the middle. The adhesive layer 11 is bonded and fixed to the first tin foil layer 14, the tin foil flange 15 and the second tin foil layer 16.

[0022] Advantageously, an adhesive edge 17 is fixedly provided at the junction of the second foil layer 16 and the middle paper layer 18. The adhesive edge 17 is used to bond and fix the edges of the second foil layer 16 and the middle paper layer 18 by means of hot pressing and adhesive.

[0023] When using this heat-resistant release paper, the first tin foil layer 14 or the silicone oil layer 19 can be used as the contact surface. Because the composite heat-resistant release paper is composed of the first tin foil layer 14, the tin foil flange 15, the second tin foil layer 16 and the silicone oil layer 19, its heat resistance is better than the original. In addition, the paper layer structural design improves the composite connection strength.

[0024] When making the heat-resistant release paper, firstly, inner holes 12 are processed in the base paper layer 13, and then adhesive layers 11 are applied to the upper and lower sides of the base paper layer 13. Since the inner holes 12 diffuse from the inside to the outside and their diameters increase sequentially, the uniform distribution effect can be improved when setting the adhesive layer 11.

[0025] Then, the first foil layer 14, the foil flange 15, and the second foil layer 16 are bonded and fixed to the original paper layer 13 by the adhesive layer 11. Then, the middle paper layer 18 is attached to the top of the original paper layer 13. Finally, the adhesive edge 17 is processed at the contact point between the second foil layer 16 and the middle paper layer 18 by hot pressing and adhesive.

[0026] Then, the processed release paper is left to stand, and the second tin foil layer 16, the adhesive edge 17 and the middle paper layer 18 are flattened. Then, a silicone oil layer 19 is processed on the upper surface of the second tin foil layer 16, the adhesive edge 17 and the middle paper layer 18.

[0027] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
