Description

Technical Field

[0001] The present invention relates to the technical field of safety doors, and in particular to a safety door production method based on homogeneous connection and a moisture-proof safety door. Background Art

[0002] In life, doors are set up to separate different spaces. In some special scenarios, there are certain requirements for the performance of the doors, such as hospitals and banks, which have certain requirements for the fire resistance and impact resistance of the doors. Such doors are called safety doors. Safety doors usually include an external steel plate and an internal core plate. The steel plate is used to improve the structural strength of the safety door and its impact resistance. The core plate is used to enhance the structural strength of the safety door, or to improve the fire resistance of the safety door. For example, a core plate containing magnesium chloride is used, which has a fireproof effect to a certain extent. However, in actual applications, it is found that the magnesium chloride core plate easily absorbs moisture in the air, causing the core plate to become damp, thereby causing the safety door to become hollow, affecting the normal use of the safety door and reducing the service life of the safety door. At the same time, if the core plate is damp, if the outside is a wooden panel, it is easy to cause the wooden panel to rot. If the outside is a metal panel, it is easy to cause the metal panel to be corroded, further reducing the service life of the safety door. Therefore, there is an urgent need in the prior art for a safety door that can enhance the moisture-proof effect of the core plate and extend the service life. Summary of the invention

[0023] Furthermore, the pre-coat layer and the coupling agent both contain resin.

[0024] Inventor's R&D process:

[0025] The inventor found in actual research that by setting up an isolation membrane to separate the core board from the outside world, the core board can be effectively reduced from being exposed to moisture in the air, thereby reducing the possibility of the core board absorbing water and getting damp, and even preventing the core board from absorbing water and getting damp. However, the surface of the isolation membrane is smooth. Due to the material properties of the isolation membrane itself, the adhesive cannot bond with the isolation membrane, so that the isolation membrane and the core board and the panel cannot be tightly connected, and the structural stability of the safety door is low. At the same time, during the production process, since the isolation membrane and the core board cannot be tightly bonded, there may be air gaps therein, and hollowing is easily produced during the production process. During the subsequent pressing process of the safety door, the air gap may break through the isolation membrane, and the moisture-proof effect of the core board cannot be effectively improved.

[0026] On this basis, the inventor conducted further research and found that the adhesive layer is pre-coated on the core board by applying pressure. After the adhesive layer is cured, an adhesive is sprayed between the adhesive layer and the panel and core board to be bonded. The adhesive and the adhesive layer have the same substance, and the bonding is achieved by fusing the same substance. The adhesive layer can be bonded to the core board and the panel respectively through the adhesive, so that the isolation film can be bonded to the core board and the panel respectively, thereby developing the technical solution of the present application. While enhancing the moisture-proof effect of the core board, the structural stability of the safety door is improved, the service life of the safety door is extended, and the yield rate is guaranteed.

[0027] Beneficial effects of basic solution 1:

[0028] This solution improves the filling pieces filled in the safety door, covers the core board with an isolation film, and separates the core board from the external environment through the isolation film, thereby blocking the entry of outside air, that is, reducing or even avoiding the contact between the core board and moisture in the air, thereby improving the moisture condition of the core board, or even avoiding the moisture of the core board, thereby enhancing the moisture-proof effect of the core board, thereby avoiding the hollowing phenomenon of the safety door and extending the service life of the safety door.

[0029] At the same time, this solution is based on the setting of the isolation film, and a pre-coating layer is coated on the isolation film. The setting of the pre-coating layer, the pre-coating layer and the bonding agent have the same substance in their components, and the pre-coating layer and the bonding agent are bonded by the same substance. The bonding agent is used to achieve close contact (i.e. bonding) between the pre-coating layer and the core plate, the first panel, and the second panel, respectively, so as to achieve bonding between the isolation film and the core plate, the first panel, and the second panel, respectively, thereby improving the structural stability of the safety door and further extending the service life of the safety door.

[0030] A second object of the present invention is to provide a moisture-proof safety door based on homogeneous connection.

[0031] The present invention provides basic solution 2: a moisture-proof safety door based on homogeneous connection, which is manufactured using the above-mentioned safety door production method based on homogeneous connection.

[0032] Further, it includes a first panel, a core panel, a second panel, and a door frame connected to the peripheral walls of the first panel and the second panel.

[0033] The surface of the core board is covered with an isolation film, and an adhesive layer is provided between the isolation film and the core board, the first panel and the second panel. The adhesive layer includes a pre-coating layer and a bonding layer. The pre-coating layer is connected to the isolation film, and the bonding layer is located between the pre-coating layer and the core board, the first panel and the second panel.

[0034] Beneficial effects of basic solution 2:

[0035] The setting of the isolation membrane separates the core board from the external environment, thereby blocking the entry of outside air, that is, reducing or even avoiding the contact between the core board and moisture in the air, thereby improving the moisture condition of the core board or even avoiding the moisture of the core board, thereby enhancing the moisture-proof effect of the core board, thereby avoiding the hollowing phenomenon of the safety door and extending the service life of the safety door.

[0036] At the same time, the pre-coating layer is set up, and the pre-coating layer and the bonding layer have the same substance in their components, and the pre-coating layer and the bonding layer are bonded by the same substance. The pre-coating layer is closely contacted (i.e. bonded) with the core plate, the first panel, and the second panel respectively through the bonding layer, so that the isolation film is bonded with the core plate, the first panel, and the second panel respectively, thereby improving the structural stability of the safety door and further extending the service life of the safety door. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 2 It is a distribution diagram of an embodiment of a moisture-proof safety door based on homogeneous connection of the present invention. DETAILED DESCRIPTION

[0039] The following is further described in detail through specific implementation methods:

[0040] The reference numerals in the drawings of the specification include: a first panel 1 , an adhesive layer 2 , a separator 3 , a core panel 4 , and a second panel 5 .

[0041] Example

[0042] The inventor found in actual research that by setting up an isolation membrane 3 to separate the core board 4 from the outside world, the core board 4 can be effectively reduced from being exposed to moisture in the air, thereby reducing the possibility of the core board 4 absorbing water and getting damp, and even preventing the core board 4 from absorbing water and getting damp. However, the surface of the isolation membrane 3 is smooth. Due to the material properties of the isolation membrane 3 itself, the adhesive cannot bond with the isolation membrane 3, so that the isolation membrane 3 cannot be tightly connected with the core board 4 and the panel, and the structural stability of the safety door is low. At the same time, during the production process, since the isolation membrane 3 and the core board 4 cannot be tightly bonded, there may be air gaps therein, and hollowing is easily generated during the production process. During the subsequent pressing process of the safety door, the air gap may break through the isolation membrane 3, and the moisture-proof effect of the core board 4 cannot be effectively improved.

[0043] On this basis, the inventor conducted further research and found that the adhesive layer 2 is pre-coated on the core board 4 by applying pressure. After the adhesive layer 2 is cured, the adhesive is sprayed between the adhesive layer 2 and the panel to be bonded and the core board 4. The adhesive and the adhesive layer 2 have the same substance, and the bonding is achieved by fusing the same substance. The adhesive layer 2 can be bonded to the core board 4 and the panel respectively through the adhesive, so that the isolation film 3 can be bonded to the core board 4 and the panel respectively, thereby developing the technical solution of the present application. While enhancing the moisture-proof effect of the core board 4, the structural stability of the safety door is improved, the service life of the safety door is extended, and the yield rate is guaranteed.

[0059] In this embodiment, the filling piece is made by the first method, and in other embodiments, the filling piece is made by the second method. The core board 4 uses the existing fire door core board 4, and in other embodiments, the core board 4 uses the magnesium chloride core board 4. The isolation film 3 uses a PE film. When making the filling piece, a pre-coating layer is set, including the following contents: coating the pre-coating layer on the side of the isolation film 3, and drying the pre-coating layer. Specifically, a foaming glue is coated on the side of the isolation film 3, and the foaming glue is cured to form a pre-coating layer.

[0065] The present solution improves the filling pieces filled in the safety door, and covers the core board 4 with an isolation membrane 3. The core board 4 is separated from the external environment by the isolation membrane 3, thereby blocking the entry of external air, that is, reducing or even avoiding the contact between the core board 4 and moisture in the air, thereby improving the condition of the core board 4 being affected by moisture, or even avoiding the core board 4 being affected by moisture, thereby enhancing the moisture-proof effect of the core board 4, thereby avoiding the hollowing phenomenon of the safety door and extending the service life of the safety door.

[0066] At the same time, this solution is based on the setting of the isolation film 3, and a pre-coating layer is coated on the isolation film 3.
