Description

Technical Field

[0001] This invention relates to the field of epoxy resin materials technology, and in particular to an epoxy resin material that transmits red light only at 600nm-700nm. Background Technology

[0002] Epoxy resins are widely used in electronic packaging, sensor manufacturing, and industrial testing due to their excellent mechanical properties, chemical resistance, and insulation properties. In some special applications, such as infrared sensitive detection, epoxy resins are required to allow only specific wavelengths of red light to pass through while shielding stray light from other wavelengths to ensure the accuracy and reliability of the detection results.

[0003] Existing epoxy resin materials have significant limitations in their light transmission bands: either they can only achieve a light transmission cutoff in the 400nm-700nm band, failing to specifically block other light rays within this range besides the target red light; or they can only achieve a light transmission cutoff in the 700nm-1100nm band, making it difficult to meet the precise light transmission requirements of the specific red light band of 600nm-700nm. Because they cannot achieve precise and sensitive identification of the infrared band and cannot effectively block other unwanted stray light, existing epoxy resins suffer from insufficient detection accuracy and specificity in applications related to red light detection in specific bands, seriously affecting the usability and user experience of industrial products.

[0004] Therefore, it is necessary to provide an epoxy resin material that transmits red light only at 600nm-700nm to solve the above-mentioned technical problems. Summary of the Invention

The light transmittance value is adjusted according to its addition amount.

[0011] Preferably, the preset ratio is a mass ratio of colorant A epoxy adhesive to colorant B epoxy adhesive of 1:1 to 3:2. This ratio enables the spectral filtering function of colorant A below 580nm and the spectral cutoff function of colorant B above 700nm to form a synergistic complementarity.

The transmission assembly includes a first gear and two second gears. The first gear is fixedly installed at the output end of the drive motor, and the two second gears are respectively meshed on both sides of the first gear. A protective cover is fixedly installed at the bottom of the top cover, covering the outer sides of the first gear and the two second gears. A first stirring shaft, two second stirring shafts, and two scraper blades are provided at the bottom of the transmission assembly. The top of the first stirring shaft is fixedly installed at the bottom of the first gear, the two second stirring shafts are respectively fixedly installed at the bottom of the two second gears, and the two scraper blades are respectively fixedly installed on both sides of the bottom of the first stirring shaft.

[0015] Preferably, one side of each of the two scraping blades is attached to the inner side of the mixing tank.

[0016] Preferably, a feed pipe is fixedly installed on the top of the top cover, a first discharge valve is fixedly installed on the bottom of the mixing tank, and multiple support frames are fixedly installed on the outer side of the mixing tank.

[0017] Preferably, a metering component is provided on the top of the top cover.

[0019] This invention provides an epoxy resin material that only transmits red light in the 600nm-700nm range. It utilizes a combination of colorant A epoxy adhesive, colorant B epoxy adhesive, and a curing agent. Colorant A filters the spectrum below 580nm, while colorant B cuts off the 700nm-1100nm spectrum. The two components are present in a synergistic and complementary mass ratio of 1:1 to 3:2.

[0029] First Embodiment

[0030] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 Transmittance characteristics of the A-color agent in the epoxy resin material that only receives 600nm-700nm red light provided by the present invention; Figure 2 Transmittance characteristics of the B-color agent in the epoxy resin material that only receives 600nm-700nm red light provided by the present invention; Figure 3 Transmittance characteristics of the epoxy resin material that transmits red light only at 600nm-700nm, provided by the present invention, after mixing colorant A and colorant B; Figure 4 A schematic diagram of the structure of the first embodiment of the mixing device for epoxy resin materials that transmits red light only at 600nm-700nm provided by the present invention; Figure 5 for Figure 4 The diagram shows the structure of the hybrid component. Figure 6 for Figure 5 The diagram shows a cross-sectional view of the top cover.

[0031] An epoxy resin material that only receives 600nm-700nm red light includes: A-color epoxy adhesive, B-color epoxy adhesive and curing agent;

[0032] The A-color epoxy adhesive is a high-efficiency red light cutoff color paste, and the B-color epoxy adhesive is a high-efficiency infrared light cutoff color paste. The A-color epoxy adhesive and the B-color epoxy adhesive are mixed in a preset ratio, a curing agent is added for curing, and then a cake-shaped solid epoxy is formed by molding. The epoxy, at a thickness of 1mm, only allows light in the 600nm-700nm wavelength band to pass through, with the central light transmission band being 650nm.

[0033] The A-color agent epoxy adhesive is a blue viscous liquid with epoxy resin as the carrier. Its viscosity is 500~1500cps / 25℃. It can be used as a masterbatch for epoxy resin for encapsulation, is suitable for light-emitting diode materials, and can filter the spectrum below 580nm.

[0034] The B-coloring agent epoxy adhesive is a blue viscous liquid with epoxy resin as the carrier. It has a high infrared filtration rate, can block the spectrum above 700nm-1100nm, and has a light transmittance of about 70% in the 400nm-700nm band. The light transmittance value is adjusted according to its addition amount.

[0035] The preset ratio is a mass ratio of epoxy adhesive A to epoxy adhesive B of 1:1 to 3:2. This ratio enables the spectral filtering function of the color agent below 580nm and the spectral cutoff function of the color agent above 700nm-1100nm to form a synergistic complement.

[0036] The cake-shaped solid epoxy is cylindrical in shape, with a diameter of 10 mm and a height of 16 mm, and a single piece weighing 3.5 g or 7 g.

[0037] The mass ratio of the curing agent to epoxy adhesive A and epoxy adhesive B is 1:8 to 1:10, and the curing conditions are 25-35℃ and standing for 24-48 hours.

[0038] Colorant A and colorant B work together, with colorant A primarily filtering short-wavelength stray light below 580nm and colorant B primarily blocking infrared stray light in the 700nm-1100nm range. Together, they achieve precise transmission of red light in the 600nm-700nm range, meeting the needs of special scenarios such as infrared-sensitive detection. The specific ratio of curing agent to the mixed system ensures that the epoxy forms stable mechanical properties and light transmission characteristics after curing.

[0039] The viscosity range of colorant A is suitable for mixing and molding processes, ensuring uniform mixing with colorant B and maintaining shape stability during molding; its viscous blue form facilitates storage and metered addition; and the epoxy resin carrier ensures compatibility with colorant B and curing agent, improving the overall performance of the product.

[0040] The high infrared filtration efficiency of the B colorant effectively shields infrared stray light interference; its controllable transmittance in the 400nm-700nm wavelength band can be adjusted by changing the amount added to meet the requirements of red light transmission intensity in different scenarios, thus enhancing the product's versatility.

[0041] The mass ratio of 1:1 to 3:2 has been optimized through multiple experiments to ensure the formation of a high light transmittance window in the 600nm-700nm wavelength band, while maximizing the shielding of stray light in other wavelength bands; the adjustable ratio design allows for fine-tuning of the dosage of the two colorants according to the stray light distribution characteristics of the actual application scenario, thereby optimizing the light transmittance effect.

[0042] The regular cylindrical structure facilitates installation and packaging, and is compatible with the installation dimensions of various testing equipment; two weight specifications can meet different usage requirements, reduce usage costs, and improve application flexibility.

[0043] Matching the curing agent ratio with the curing conditions ensures that the epoxy is fully cured, resulting in excellent mechanical strength and environmental resistance. The room temperature curing process requires no special equipment, reducing production difficulty and cost, and is suitable for mass production.

[0044] The mixing process requires a mixing device, which includes a mixing tank 1. A top cover 4 is fixedly installed on the top of the mixing tank 1. A drive motor 6 is fixedly installed on the top of the top cover 4. A transmission assembly 9 is provided at the bottom of the top cover 4. The transmission assembly 9 includes a first gear 91 and two second gears 92. The first gear 91 is fixedly installed at the output end of the drive motor 6. The two second gears 92 are respectively meshed on both sides of the first gear 91. A protective cover 7 is fixedly installed at the bottom of the top cover 4, covering the outer sides of the first gear 91 and the two second gears 92. A first stirring shaft 81, two second stirring shafts 82, and two scraper plates 83 are provided at the bottom of the transmission assembly 9. The top of the first stirring shaft 81 is fixedly installed at the bottom of the first gear 91. The two second stirring shafts 81 are respectively fixedly installed at the bottom of the two second gears 92. The two scraper plates 83 are respectively fixedly installed on both sides of the bottom of the first stirring shaft 81.

[0045] One side of each of the two scraping blades 83 is attached to the inner side of the mixing tank 1.

[0046] The top of the top cover 4 is fixedly installed with a feed pipe 5, the bottom of the mixing tank 1 is fixedly installed with a first discharge valve 3, and the outer side of the mixing tank 1 is fixedly installed with multiple support frames 2.

[0047] When using the product, first, according to the preset ratio (mass ratio of epoxy adhesive A to epoxy adhesive B 1:1~3:2), add the two colorants into the mixing tank 1 through the feed pipe 5 on the top cover 4. Then, add the curing agent according to the mass ratio of the mixed system (colorant A + colorant B) to the curing agent 1:8~1:10. After closing the sealing structure of the feed pipe 5, start the drive motor 6. The output shaft of the drive motor 6 drives the first gear 91 in the transmission assembly 9 to rotate. Since the two second gears 92 are respectively meshed on both sides of the first gear 91, the first gear 91 will synchronously drive the two second gears 92 to rotate in opposite directions. Consequently, the first stirring shaft 81 at the bottom of the first gear 91 and the second stirring shaft 82 at the bottom of the two second gears 92 rotate synchronously, forming... The multi-shaft coordinated stirring effect thoroughly mixes the three materials in the mixing tank 1, ensuring uniform mixing of each component. During stirring, the scraper plates 83 on both sides of the bottom of the first stirring shaft 81 always adhere to the inner side of the mixing tank 1 and rotate synchronously with the stirring shaft, scraping the material adhering to the tank wall into the tank to avoid material residue causing waste or proportion deviation. The protective cover 7 protects the first gear 91 and the second gear 92, preventing material from entering the transmission components and affecting transmission stability. After mixing is completed, the drive motor 6 is turned off, and the first discharge valve 3 at the bottom of the mixing tank 1 is opened to discharge the uniformly mixed material for subsequent curing and molding processes. The support frame 2 on the outside of the mixing tank 1 provides stable support for the entire device, ensuring smooth operation of the device during stirring.

[0048] Compared with related technologies, the epoxy resin material provided by this invention, which transmits red light only at 600nm-700nm, has the following beneficial effects:

[0049] By combining epoxy adhesives of color agent A and color agent B, along with a curing agent, color agent A filters the spectrum below 580nm, while color agent B cuts off the spectrum from 700nm to 1100nm. The two are synergistically complementary in a mass ratio of 1:1 to 3:2. After curing, the epoxy only allows red light in the 600nm-700nm band to pass through, effectively shielding other stray light and improving detection accuracy. This solves the problem that existing epoxy resins cannot accurately filter red light in the 600nm-700nm range, and that stray light interference leads to insufficient detection accuracy.

[0050] Second Embodiment

[0051] Please refer to the following: Figure 7 Based on the first embodiment of this application, which provides an epoxy resin material that transmits red light only in the 600nm-700nm range, the second embodiment of this application proposes another epoxy resin material that transmits red light only in the 600nm-700nm range. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0052] Specifically, the difference in the second embodiment of this application regarding an epoxy resin material that only receives 600nm-700nm red light is that, in this epoxy resin material that only receives 600nm-700nm red light, a metering component 10 is provided on the top of the top cover 4. The metering component 10 includes a support frame 101, four weighing sensors 102, a storage tank 103, a display screen 104, and a second discharge valve 105. The support frame 101 is fixedly installed on the top of the top cover 4, the four weighing sensors 102 are all fixedly installed on the top of the support frame 101, the storage tank 103 is fixedly installed on the top of the four weighing sensors 102, the display screen 104 is fixedly installed on the front of the storage tank 103, and the second discharge valve 105 is fixedly installed on the bottom of the storage tank 103 and located on the top of the feed pipe 5.

[0053] The working principle of the epoxy resin material that transmits red light only in the 600nm-700nm range provided by this invention is as follows:

[0054] First, according to the preset ratio (mass ratio of colorant A epoxy adhesive to colorant B epoxy adhesive 1:1~3:2), the two colorants are metered and prepared separately. Colorant A epoxy adhesive is added to the storage tank 103 of the metering component 10. Four weighing sensors 102 detect the total weight of the storage tank 103 and the colorant inside in real time, and the weight data is displayed on the display screen 104. When the preset weight is reached, the feeding stops, the second discharge valve 105 is opened, and colorant A flows precisely into the mixing tank 1 through the feed pipe 5. Following the same process, colorant B epoxy adhesive is weighed and added through another metering component (or the same metering component after being emptied) to ensure accurate mixing ratio of the two colorants. Subsequently, according to the mass ratio of the mixed system (colorant A + colorant B) to the curing agent of 1:8~1:10, the curing agent is added to the mixing tank 1 through the feed pipe 5.

[0055] Compared with related technologies, the epoxy resin material provided by this invention, which transmits red light only at 600nm-700nm, has the following beneficial effects:

[0056] With the setting of the metering component 10, the weighing sensor 102 accurately detects the weight of colorant A and colorant B during use, and the display screen 104 displays the data in real time, ensuring that the two are added in the preset ratio of 1:1 to 3:2, and avoiding the failure of the stray light filtering function due to the ratio deviation.

[0057] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
