Description

Technical Field

[0001] The present invention relates to the technical field of surface modification, and further relates to a thin film silanization surface modification system. Background Art

[0002] Flexible polymer thin film materials such as polyimide, polyester, fluoroplastics, etc. are key materials for spacecraft surfaces due to their light weight, good processing performance, excellent mechanical properties, and excellent light and heat properties, and are used to effectively protect spacecraft from the adverse space environmental factors in low Earth orbit. There are a large number of highly oxidizing atomic oxygen in the space environment of low Earth orbit. The highly kinetic and highly oxidation-active atomic oxygen is likely to cause severe erosion to the polymer thin film materials on the surface of the spacecraft, thus seriously affecting the service life of the spacecraft. Therefore, it is necessary to carry out protective treatment on the polymer thin film materials of spacecraft components. The key technology developed recently is to form a protective layer with a gradually changing composition gradient through anti-atomic oxygen surface modification, which can solve the problem of atomic oxygen erosion of polymer thin film materials and retain the original use performance of the polymer materials.

[0003] With the continuous iterative development of spacecraft, higher requirements are put forward for the size and performance of polymer thin films. The surface modification systems in the prior art can only better complete the modification treatment of small-sized thin film materials, and the thin film fixing devices in the prior art surface modification systems are only suitable for processing semi-rigid materials, and it is difficult to complete the modification treatment of large-sized flexible thin film materials. There is a problem of substrate damage in the fixation of flexible thin film materials. Summary of the Invention

[0004] Aiming at the above technical problems, the purpose of the present invention is to provide a thin film silanization surface modification system and a use method, which solve the problems in the prior art.

[0005] To achieve the above purpose, the present invention provides a thin film silanization surface modification system, including:

[0006] A thin film fixing device, including a fixing frame, and a plurality of clamping components are arranged on the inner frame of the fixing frame. The clamping components are used to fix and extend the thin film to be processed on the fixing frame;

[0007] A thin film silanization treatment device, including a first housing, a first accommodation cavity is opened in the first housing, a reaction container is arranged in the first accommodation cavity, a reaction tank is opened in the reaction container, the reaction tank is filled with a silane reagent, and first heating devices are further arranged on both sides of the reaction container corresponding to the reaction tank. The first heating devices are used to heat the silane reagent to accelerate the silanization reaction. The reaction tank matches the fixing frame, so that the thin film to be processed can be unfolded in the reaction container through the fixing frame and undergo silanization treatment;

[0008] The film heat treatment device is used for heating and drying the film to be treated that has been silanized.

[0009] The film to be treated is fixed and unfolded in the inner frame under the clamping action of the clamping assembly, and then the fixed frame holding the film to be treated is transferred to the reaction tank manually or by a lifting mechanism, and is fully contacted with the silane reagent heated by the first heating device in the reaction tank, so that the surface of the film to be treated completes the activated silanization reaction, and then the film to be treated and the fixed frame that have completed the silanization reaction are transferred from the reaction tank to the film heat treatment device manually or by a lifting mechanism, and the silanized film to be treated is heated and dried, thereby completing the surface modification of the film to be treated.

[0010] In some embodiments, the fixing frame includes:

[0011] A concave connecting member, the concave connecting member being arranged on a side of the fixing frame close to the clamping assembly;

[0031] In some embodiments, a second opening is opened on the other side wall of the second housing corresponding to the first opening, and a second sealing door is detachably connected to the second opening;

[0032] The number of the film heat treatment devices is two, and the two film heat treatment devices are connected by a plurality of connection components, and the first opening and the second opening are in contact correspondingly.

[0034] In some embodiments, the connection components include:

[0035] Two connecting pieces, which are respectively arranged at corresponding positions on the two film heat treatment devices;

[0036] A connecting bolt, which connects the two connecting pieces through a fastening nut.

[0037] Through a film silanization surface modification system provided by the present invention, at least one of the following beneficial effects can be brought:

[0038] 1. The thin film silanization surface modification system provided by the present invention solves the problem of fixing the thin film to be processed by adding a thin film fixing device. At the same time, a reaction vessel matching the fixing frame is set, so that the thin film to be processed can enter the reaction tank in the reaction vessel in a state of being unfolded and fixed, so that the thin film can fully contact with the silane reagent in the reaction tank, and then under the heating action of the first heating device, the silanization treatment is accelerated. Then, the thin film to be processed that has been silanized is put into the thin film heat treatment device for heating and drying treatment, so that the surface of the thin film to be processed after the activated silanization reaction is heat-stabilized.

[0058] In one embodiment, the reference specification Figure 1 As shown, a thin film silanization surface modification system provided by the present invention includes a thin film fixing device 20, a thin film silanization treatment device 30 and a thin film heat treatment device 40, wherein the thin film fixing device 20 includes a fixing frame 21, and a plurality of clamping components are arranged on the inner frame of the fixing frame 21, and the clamping components are used to fix and extend the film 10 to be treated on the fixing frame 21, and the thin film silanization treatment device 30 includes a first shell 32, and the first shell 32 is provided with a first accommodating cavity, and a reaction container is arranged in the first accommodating cavity, and a reaction tank is arranged in the reaction container, and the reaction tank is filled with a silane reagent, and a first heating device is also arranged on both sides of the reaction container corresponding to the reaction tank, and the first heating device is used to heat the silane reagent to accelerate the silanization reaction, and the reaction tank is matched with the fixing frame 21, so that the film 10 to be treated can be unfolded in the reaction container through the fixing frame 21 and subjected to silanization treatment, and the thin film heat treatment device 40 is used to heat and dry the film 10 to be treated that has been subjected to silanization treatment.

[0059] Specifically, a placement opening is opened on the top of the first shell 32, and a sealing cover 35 is also provided on the placement opening. The film 10 to be treated is fixed and unfolded in the inner frame under the clamping action of the clamping assembly, and then the fixed frame 21 clamping the film 10 to be treated is transferred to the reaction tank manually or by a lifting mechanism, and then fully contacted with the silane reagent in the reaction tank. Under the heating action of the first heating device, a silanization reaction is quickly carried out to complete the activation silanization reaction on the surface of the film 10 to be treated, and then the film 10 to be treated and the fixed frame 21 that have completed the silanization reaction are transferred from the reaction tank to the film heat treatment device 40 manually or by a lifting mechanism, and the silanized film 10 to be treated is heated and dried, thereby completing the surface modification of the film 10 to be treated.

[0060] It should be noted that the maximum processing size of the thin film 10 to be processed is 3 m in length and 1 m in width. The inner frame size of the fixed frame 21 is slightly larger than that of the thin film 10 to be processed. The size of the fixed frame 21 can be 3.2 m in length and 1.2 m in width. The number of clamping components is 22. Among them, 8 clamping components are arranged on each of the two long sides of the inner frame, and 3 clamping components are arranged on each of the two short sides.

[0061] In one embodiment, referring to the attached drawings of the specification Figures 2 to 4 As shown, the fixed frame 21 includes a concave connecting member 24 and an L-shaped connecting member 25. The concave connecting member 24 is arranged on the side of the fixed frame 21 close to the clamping component, and the L-shaped connecting member 25 is arranged on the side of the clamping component close to the concave connecting member 24.

[0064] Specifically, through the corresponding engagement of the concave tooth structure and the convex tooth structure, the film 10 to be processed is effectively prevented from falling off. By adjusting the manual butterfly screw 231, the clamping force of the pressing member 23 is adjusted, and then the pressure of the film 10 to be processed clamped on the two sets of clamping strips is adjusted, effectively avoiding the situation that the film 10 to be processed falls off due to too small clamping force or the film 10 to be processed is damaged due to too large clamping force.

[0065] In one embodiment, referring to the attached drawings of the specification Figure 6 As shown, the reaction tank includes an upper tank 33 and a lower tank 34 vertically communicating with the upper tank 33.

Each group of heating tubes is symmetrically arranged side by side and attached to the two side walls of the reaction tank.

[0069] It should be noted that the film silanization treatment device 30 is also provided with a temperature control system, which is arranged on the first housing 32 and used to independently detect and control each group of heating tubes, so as to effectively reduce the temperature difference at both ends of the reaction tank and ensure the temperature uniformity when the film 10 to be processed is heated and silanized.

[0070] In one embodiment, referring to the attached drawings of the specification Figure 1 and Figure 7As shown, the thin film heat treatment device 40 includes a second housing 47.

[0071] In one embodiment, on the basis of the above embodiment, referring to the attached drawings of the specification Figure 1 and Figure 7 As shown, a first opening is provided on the side wall of the placement container. A first sealing door 43 is detachably arranged at the first opening. The thin film heat treatment device 40 further includes a moving track 41 and a moving support 42 corresponding to the moving track 41. The moving track 41 is arranged at the bottom of the placement container and extends outwards through the first opening. A fixing seat for fixing the fixing frame 21 is arranged on the moving support 42, so that the to-be-treated thin film 10 can be transferred to a predetermined position of the placement container along the moving track 41.

[0072] Specifically, the opening of the drying groove is arranged on the side surface of the second housing 47 and is communicated with the first opening. The fixing frame 21 with the thin film 10 is fixed on the moving support 42. A plurality of wheels corresponding to the moving track 41 are arranged at the bottom of the moving support 42, so that the moving support 42 is transferred to a predetermined position of the placement container along the moving track 41, and then the first sealing door 43 is closed, so that the placement groove 48 forms a sealed space to make the heating and drying effect better. The moving track 41 enables the fixing frame 21 with the to-be-treated thin film 10 to be quickly and stably conveyed into the drying groove.

[0073] It should be noted that universal wheels are arranged at the bottoms of both the second housing 47 and the moving support 42 to facilitate the movement of the entire thin film heat treatment device 40.

[0081] It should be noted that the connecting component further includes a flat gasket 53 and a baffle 54. The flat gasket 53 is sleeved on the connecting bolt 51 to make the fastening relationship between the two connecting pieces firmer. The connection part of the two thin film heat treatment devices 40 can also be sealed with a high-temperature resistant sealing rubber ring.
