Description

Technical Field

[0001] This utility model mainly relates to the technical field of epoxy resin distillation, specifically a distillation apparatus for silicon-modified epoxy resin. Background Technology

[0002] Epoxy resins are an important class of thermosetting plastics, containing two or more epoxy groups in their molecular structure. Epoxy resins refer to a general term for polymers with two or more epoxy groups in their molecular structure. These epoxy groups, under appropriate chemical catalysts or high-temperature conditions, can undergo ring-opening addition reactions with various compounds to form three-dimensional network structures. Silicon-modified epoxy resins can be used to manufacture high-voltage capacitors, printed circuit boards, and packaging materials, meeting the electronics industry's demand for high-performance materials. The preparation of silicon-modified epoxy resins typically involves the reaction of siloxanes with epoxy resins; the specific process may vary depending on the product type and application requirements. During processing, it is necessary to carefully control the reaction conditions and process parameters to ensure product quality and performance. Distillation of silicon-modified epoxy resins is mainly to remove low-molecular-weight compounds, unreacted raw materials, and solvents generated during the reaction, thereby improving the purity and quality of the product. Through distillation, purer silicon-modified epoxy resins can be obtained to meet the needs of subsequent applications.

[0003] According to application number CN201621416246.8, a distillation apparatus for epoxy resin production includes a base frame, a base, and a distillation chamber.

[0026] A through hole 101 is provided at the bottom of the base plate 10, a heating element 102 is provided at the top of the base plate 10 and on one side of the U-shaped plate 11, and a flask 103 is provided at the top of the heating element 102 and at the bottom of the U-shaped plate 11.

[0027] The adjusting support rod 12 includes a support rod 121 that passes through the top of one end of the U-shaped plate 11. A support collar 122 is provided on the top of the side wall of the support rod 121. A metal block 123 is provided on the bottom of the side wall of the support rod 121 and located at one end of the U-shaped plate 11. A metal hoop 124 is provided at the bottom of the metal block 123. A tightening block 125 is fitted at the bottom of the metal hoop 124.

[0028] The support collar 122 is fitted onto the bottom of the outer wall of the distillation tube 13, and the outer wall of the metal hoop 124 is slidably connected to the inner wall of the tightening block 125.

[0029] The bottom of one end of the distillation tube 13 is provided with a sleeve 131, which is fitted onto the top opening of the flask 103.

[0030] The cooling pipe 14 has external interfaces 141 at both ends of its bottom.

[0031] The guide tube 15 is inclined, and multiple guide branches 151 are provided on the side wall of the guide tube 15. The guide branches 151 are located at the top of the collection tube 16.

[0032] The bottom of the collection tube 16 is provided with a support frame 161, and the side wall of the support frame 161 is provided with an angle adjustment knob 162.

[0033] It should be noted that in this embodiment, a U-shaped clamping plate 11 is provided at the top end of the chassis 10, which serves to fix and support the subsequent components.

[0034] The adjustable support rod 12 can be adjusted up and down to accommodate flasks 103 of different sizes.

[0035] A distillation conduit 13 is provided at the top end of the adjusting strut 12. The distillation conduit 13 is used to introduce the silicon-modified epoxy resin vapor in the flask 103 into the subsequent cooling device.

[0036] A cooling tube 14 is fitted onto the top of the distillation conduit 13. This cooling tube 14 is used to cool the vapor into a liquid. A guide tube 15 is connected to the bottom of one end of the cooling tube 14, which is located at one end of the distillation conduit 13. The function of the guide tube 15 is to guide the cooled liquid into the collection test tube 16.

[0037] On one side of the guide tube 15, there is a collection tube 16, which is used to collect the cooled silicone-modified epoxy resin liquid.

[0038] The heating element 102 is used to heat the silicon-modified epoxy resin in the flask 103, causing it to evaporate.

[0039] To further optimize the function of the device, we have made a through hole 101 at the bottom of the base 10. The through hole 101 is used to directly place the flask 103 and to dissipate heat and exhaust air from the bottom of the heating element, so as to avoid damage to the heating element due to long-term operation.

[0040] The specific structure of the adjusting strut 12 includes a straight support rod 121 passing through the top of one end of the U-shaped clamping plate 11. A support collar 122 is located at the top of the side wall of the straight support rod 121, and is used to fit around the bottom of the outer wall of the distillation tube 13, providing support and fixation. At the bottom of the side wall of the straight support rod 121, located at one end of the U-shaped clamping plate 11, is a metal hoop 124 at the bottom of a metal clamping block 123, and a tightening block 125 is fitted around the bottom of the metal hoop 124. The tightening block 125 is slidably connected to the outer wall of the metal hoop 124, and the height of the straight support rod 121 can be changed by adjusting the position of the tightening block 125, thereby accommodating flasks 103 of different sizes.

[0041] A sleeve 131 is provided at the bottom of one end of the distillation tube 13. The sleeve 131 is fitted onto the top opening of the flask 103 to ensure that the vapor can be smoothly discharged from the flask 103.

[0042] The external interfaces 141 at both ends of the bottom of the cooling pipe 14 can be used to connect to a cooling water source or other cooling medium to provide the cooling effect required by the cooling pipe 14.

[0043] The guide tube 15 is inclined, and there are multiple guide branches 151 on its side wall. These guide branches 151 are located at the bottom of the collection tube 16, which can evenly guide the cooled liquid into the collection tube 16 and prevent the liquid from splashing out or accumulating in a certain part of the guide tube 15.

[0044] A support frame 161 is located at the bottom of the collection tube 16 to support it and keep it stable. An angle adjustment knob 162 is located on the side wall of the support frame 161. The knob can be used to adjust the tilt angle of the collection tube 16, allowing the user to adjust the position and angle of the collection tube 16 as needed.

[0045] The working principle of this utility model is as follows:

[0046] By placing a flask 103 containing silicone-modified epoxy resin on a U-shaped clamp 11, the silicone-modified epoxy resin in the flask 103 is heated to evaporate. The epoxy resin gas is fitted through a sleeve 131 at the top opening of the flask 103, ensuring that the vapor can be smoothly discharged from the flask 103.

[0047] The external interfaces 141 at both ends of the bottom of the cooling pipe 14 can be used to connect to a cooling water source or other cooling medium to provide the cooling effect required by the cooling pipe 14.

[0048] The guide tube 15 is inclined, and the guide branch tube 151 is located at the bottom of the collection tube 16, which can evenly guide the cooled liquid into the collection tube 16 and prevent the liquid from splashing out or accumulating in a certain part of the guide tube 15.

[0049] Finally, the samples were collected using test tube 16.

[0050] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
