[0002] Photosensitive materials appeared along with the emergence of photography technology. With continuous development and innovation, due to their own special properties, artists have applied photosensitive materials to more artistic creations, creating uniquely beautiful works of art that show vivid and rich artistic effects.

[0003] However, the inventors of this application have discovered that the photosensitive materials currently on the market have certain defects: when existing photosensitive materials are used for artistic creation in outdoor environments, due to long-term exposure to sunlight, the photosensitive materials degrade and age under the action of ultraviolet rays, and fade, losing their original bright colors. At the same time, their luminous effects also decay to varying degrees, making it impossible for the artwork to maintain a rich and colorful visual effect for a long time. Summary of the invention

[0004] In view of the problem that photosensitive materials in the prior art fade and lose their luminous effect due to long-term exposure outdoors, a new outdoor photosensitive material is provided. The material adopts a highly durable, brightly colored, and antioxidant automobile paint masterbatch and a rare earth aluminate long afterglow luminous raw powder with strong light storage capacity and long luminescence time as raw materials, achieving the effect of no fading and no decay of luminous performance when used outdoors for a long time.

[0024] In the above embodiment, the outdoor photosensitive material further includes a mixture of resin and diluent, and the volume ratio of the resin to the diluent in the mixture is 1:(1-1.5).

[0025] In one embodiment, the outdoor photosensitive material further comprises a light stabilizer and an ultraviolet absorber. Preferably, the weight ratio of the rare earth aluminate long afterglow luminous raw powder, automobile paint masterbatch, light stabilizer and ultraviolet absorber in each liter of the mixed solution is (0.8-1.5): (0.015-0.1): 0.003: 0.003.

[0026] As a preferred embodiment, the resin is 1K oily resin.

[0027] The present invention also provides a method for preparing the outdoor photosensitive material, which comprises the following specific steps:

[0075] Example 7

[0076] In this embodiment, a luminous effect test is performed on the outdoor photosensitive material provided in this application.

[0077] Test method: Use a 365nm 500W light-efficient UV lamp to irradiate outdoor photosensitive materials for 10 seconds, and use a illuminance meter to measure the brightness value (unit: FC, i.e. the amount of light passing through per square foot).

[0078] It should be noted that in this test, yellow-green outdoor photosensitive material was used as the test material, and yellow-green rare earth aluminate long afterglow luminous original powder and lemon yellow automobile paint masterbatch were selected as raw materials. The reason is that this kind of material and color are highly versatile, relatively stable, and have a small data deviation value.

[0079] The specific proportions of the components in the three groups of outdoor photosensitive materials and the test results are as follows:

[0080] (1) Test Example 1:

[0081] The volume ratio of 1K oily resin and universal diluent is 1:1.5. The mass ratio of yellow-green rare earth aluminate long afterglow luminous original powder, lemon yellow automobile paint masterbatch, light stabilizer and ultraviolet absorber in each liter of mixed liquid is 0.5:0.02:0.003:0.003. All components are weighed according to the above proportion and mixed evenly to prepare outdoor photosensitive materials.

[0082] Test results: The test brightness value is 24FC, the luminous effect is poor and cannot meet the process standards.

[0083] (2) Test Example 2:

[0084] Refer to Test Example 1, the difference is that the mass ratio of the yellow-green rare earth aluminate long afterglow luminous raw powder, the yellow-green automobile paint masterbatch, the light stabilizer and the ultraviolet absorber in each liter of mixed liquid is 1:0.02:0.003:0.003.

[0085] Test results: The test brightness value is 62FC, and the luminous effect is good. At the same time, the outdoor photosensitive material is coated on the surface of the substrate. After drying, the surface is stable and has strong adhesion, which can meet the process standards.

[0086] (3) Test Example 3:

[0087] Refer to test example 1, the difference is that the mass ratio of yellow-green rare earth aluminate long afterglow luminous raw powder, yellow-green automobile paint masterbatch, light stabilizer and ultraviolet absorber in each liter of mixed liquid is 2:0.02:0.003:0.003.

[0088] Test results: The test brightness value is 98FC, and the luminous effect is good. However, when the outdoor photosensitive material is coated on the surface of the substrate, due to the excessive specific gravity of the rare earth aluminate long afterglow luminous original powder, the surface is very easy to fall off and damage after drying, and it cannot meet the process standards.

[0089] Example 8

[0090] In this embodiment, a masterbatch brightness test is performed on the outdoor photosensitive material provided in this application.

[0091] Test method: human visual identification.

[0092] It should be noted that in this test, yellow-green outdoor photosensitive material was used as the test material, and yellow-green rare earth aluminate long afterglow luminous original powder and lemon yellow automobile paint masterbatch were selected as raw materials. The reason is that this kind of material and color are highly versatile, relatively stable, and have a small data deviation value.

[0093] The proportions of each component in the three groups of outdoor photosensitive materials and the test results are as follows:

[0094] 1) Test Example 1:

[0095] The volume ratio of 1K oily resin and universal diluent is 1:1.5. The mass ratio of yellow-green rare earth aluminate long afterglow luminous powder, lemon yellow automobile paint masterbatch, light stabilizer and ultraviolet absorber in each liter of mixed liquid is 1:0.010:0.003:0.003. All components are weighed according to the above proportion and mixed evenly to prepare outdoor photosensitive materials.

[0096] Test results: The yellow color is not bright enough. When the outdoor photosensitive material is coated on the surface of the substrate, the color is uneven and whitish, which cannot meet the process standards.

[0097] (2) Test Example 2:

[0098] Refer to Test Example 1, the difference is that the mass ratio of the yellow-green rare earth aluminate long afterglow luminous raw powder, lemon yellow automobile paint masterbatch, light stabilizer and ultraviolet absorber in each liter of mixed liquid is 1:0.02:0.003:0.003.

[0099] Test results: The color is bright and vivid. When the outdoor photosensitive material is coated on the surface of the substrate, the color is uniform and the surface is smooth, which can meet the process standards.

[0100] (4) Test Example 3:

[0101] Refer to test example 1, the difference is that the mass ratio of yellow-green rare earth aluminate long afterglow luminous raw powder, lemon yellow automobile paint masterbatch, light stabilizer and ultraviolet absorber in each liter of mixed liquid is 1:0.2:0.003:0.003.

[0102] Test results: The color is very vivid and the color coating is uniform. However, when the outdoor photosensitive material is coated on the surface of the substrate, the content of the lemon yellow car paint masterbatch is too saturated, which covers the photosensitive material, affecting the luminous effect at night and failing to meet the process standards.

[0103] Example 9

[0104] Based on Examples 1 to 8, this example provides a method for using the outdoor photosensitive material. Taking the coating of an outdoor sculpture as an example, the specific process is as follows:

[0105] (1) First clean, degrease and polish the surface of the substrate

[0106] Taking the outdoor sculpture substrate as 304 stainless steel as an example, first clean the substrate surface, use degreaser to remove the surface oil sludge and dirt, and use 80-400# sandpaper to grind the surface welding points and uneven areas to make the substrate surface relatively flat and clean. This step is a preliminary preparation process. If it is not thoroughly polished and cleaned, it will lead to low adhesion of the subsequent coating and surface blistering.

[0107] (2) Epoxy coating

[0108] The epoxy coating is prepared by mixing an epoxy primer, an epoxy curing agent and an epoxy primer thinner, wherein the volume ratio of the above components is 4:1:3.

[0109] According to the coating area and coating times of the substrate, the estimated dosage is measured according to the above volume ratio, epoxy primer, epoxy curing agent and epoxy primer thinner are mixed to form an epoxy coating solution, and sprayed evenly on the surface of the 304 stainless steel substrate with a paint spray gun. Spray twice. The number of spraying here can be adjusted according to the actual demand effect.

[0110] The main function of epoxy coating is to make the metal substrate have better adhesion. All metal substrate surfaces require epoxy primer as a base coating for painting to pave the way for the subsequent scraping of sheet metal ash.

[0111] (3) Scrape and apply sheet metal ash

[0112] After the epoxy coating is dry, the surface is smooth and needs to be polished with 600# sandpaper. Polishing with sandpaper can improve the friction between the coatings. If there are uneven areas on the substrate or deep marks left by sandpaper, sheet metal ash needs to be scraped and filled. After the sheet metal ash is dry, use 120~1500# sandpaper to polish the sheet metal ash and surrounding areas to make the overall surface of the substrate smooth and smooth.

[0113] Compared with ordinary putty, sheet metal putty has higher hardness, stronger adhesion, is not easy to crack, and has higher durability.

[0114] Use multiple layers of sandpaper from coarse to fine to make the surface smooth and clean, which is convenient for the subsequent spraying of primer.

[0115] (4) Apply the intermediate white primer coating

[0116] The intermediate white primer coating is prepared by mixing an intermediate white primer, an intermediate primer curing agent and an intermediate primer thinner, and the volume ratio of the above components is 4:1:3.

[0117] The role of the white primer coating during the painting process is to compensate for the uneven color left by the construction of the sheet metal ash in step (3) or the uneven surface caused by sandpaper marks, playing a connecting role.

[0118] After the sheet metal ash in step (3) is dried, the amount is estimated according to the coating area and the number of coatings of the substrate, and the intermediate white primer coating solution prepared by mixing the intermediate white primer, the intermediate primer curing agent and the intermediate primer thinner is measured according to the above volume ratio, and sprayed three times with a paint spray gun. The number of spraying times is not limited here. However, it should be noted that the intermediate white primer coating solution must be sprayed evenly. The spraying uniformity of the colored outdoor photosensitive material is closely related to the uniformity of the intermediate white primer coating. If the spraying is uneven, it will cause the shadow problem of the photosensitive layer.

[0119] After the white primer coating is completely dry, use sandpaper to smooth its surface. Uneven grinding will cause sagging. Use fine sandpaper to grind but do not grind through or expose the bottom. The finer the surface of the primer coating, the finer the surface of the outdoor photosensitive material coating and the subsequent hard coating.

[0120] (5) Coating of outdoor photosensitive materials

[0121] According to the needs of actual application scenarios, the substrate can be coated with photosensitive materials of different colors and evenly sprayed with a paint spray gun. The number of spraying times can be adjusted according to the actual spraying situation, preferably 6 to 8 times.

[0122] (6) Hard coating

[0123] The hard coating uses crystal varnish, varnish thinner, curing agent and drying accelerator, wherein the volume ratio of the crystal varnish to the curing agent is 2:1, and the weight ratio of the varnish thinner to the drying accelerator is 3:1.

[0124] Among them, the crystal varnish is preferably Akzo Nobel crystal varnish.

[0125] Estimate the amount according to the coating area and number of coatings of the substrate, measure the crystal varnish, varnish thinner, curing agent and drying accelerator respectively, mix them to make hard coating varnish, use a paint spray gun to spray evenly, there is no limit to the number of spraying times, it is preferred to spray two layers of hard coating varnish, spray each layer 4 times, that is, spray once and wait for it to be completely dry before spraying the next time, repeat the spraying 4 times as one layer.

[0126] Because there are too many coating processes at the beginning, the original coating has a certain thickness. After spraying the first layer of hard coating varnish, it is easy to be absorbed by the original coating, and there will be a certain loss of gloss. In addition, the particle size and thickness of the rare earth aluminate long afterglow luminous original powder will cause the surface to have too heavy orange peel texture. Therefore, a drying accelerator is added to the first layer of hard coating varnish to make it dry more thoroughly and faster. After the first layer of hard coating varnish is sprayed, use 2000# sandpaper to polish off the surface orange peel texture to make the surface more delicate and smooth, and then spray the second layer of hard coating varnish. No need to add a drying accelerator in the second spraying, and wait for it to dry naturally.

[0127] (7) Surface polishing

[0128] The orange peel texture on the surface of the sculpture needs to be finely ground with 2000-5000# polishing sandpaper and polished with polishing wax to make the surface smoother and more delicate, with better anti-fouling ability and less likely to leave watermarks and stains.

[0129] The outdoor colored photosensitive material provided by the present invention is used to paint outdoor sculptures, wherein the photosensitive layer base is a rare earth aluminate long afterglow luminous original powder with strong light storage ability and long luminescence time. It absorbs various lights and heat in bright environment, converts them into light energy for storage, and then automatically emits light in the dark. It can be recycled an unlimited number of times and has a faster absorption effect on sunlight and ultraviolet light.

[0130] At the same time, adding automobile paint masterbatch with good dispersibility can improve the dispersibility and tinting strength of the pigment. The automobile paint masterbatch also has good stability, which can prevent the pigment from absorbing water and oxidizing during use, and can keep the color of the material stable for a long time.

[0131] In addition, the addition of light stabilizers and ultraviolet absorbers can significantly reduce the luminous decay of outdoor photosensitive materials.

[0132] In summary, the outdoor color photosensitive material provided by the present invention can achieve the effect of not fading during long-term outdoor use, having strong UV resistance and no decay of luminous performance, thereby increasing service life and enhancing reliability.

[0133] At the same time, the present invention also provides a method for using the material in an outdoor environment, wherein a high-hardness crystal varnish is used on the surface of the sculpture as an anti-fouling protective layer, which has anti-oxidation and anti-fouling functions. The sculpture maintenance only requires wiping the surface with clean water regularly, which is convenient for long-term exhibition and maintenance.

[0134] In addition, in this embodiment, the paint thickness and durability of the hard coating are tested according to different spraying times, as follows:

[0135] Test materials: The materials for the hard coating are Akzo Nobel crystal varnish, varnish thinner, curing agent, and drying accelerator, which are evenly mixed to form a hard coating varnish, wherein the volume ratio of Akzo Nobel crystal varnish to curing agent is 2:1, and the weight ratio of varnish thinner to drying accelerator is 3:1.

[0136] Spraying method: Spray one layer of hard coating with 4 coats of hard coating varnish, wait for it to dry completely before spraying the next layer.

[0137] Test method: After the outdoor photosensitive material coating on the substrate surface is completely dry, spray the hard coating varnish, and use an instrument to measure the paint thickness after it is completely dry.

[0138] The paint thickness of three test cases with different spraying times was tested, and the test results are as follows:

[0139] (1) Test Example 1:

[0140] Spray one coat of hard coat, that is, spray 4 coats of hard coat clear.

[0141] Test results: The paint thickness measured by the instrument is 302μm, the surface hardness is low, it cannot resist stains, the decontamination ability is weak, it cannot be stored outdoors for a long time, and it cannot meet the process standards.

[0142] (2) Test Example 2:

[0143] Spraying two layers of hard coating: Referring to Test Example 1, after the first layer of hard coating is dried, it is polished and smoothed, and a second spraying is performed, that is, 8 layers of hard coating varnish are sprayed.

[0144] Test results: The paint thickness measured by the instrument is 433μm, the surface hardness is relatively high, the anti-fouling and decontamination properties are good, it can be stored outdoors for a long time, and meets the process standards.

[0145] (3) Test Example 3:

[0146] Spraying three layers of hard coating: Refer to Test Example 1, after each layer is dried, it is polished and smoothed before spraying the next layer, that is, spraying the hard coating varnish 12 times.

[0147] Test results: The paint thickness measured by the instrument is 600μm, but because the hard coating is too thick, the paint surface forms orange peel texture, cracks and bubbles, and cannot meet the process standards.

[0148] Combined with the test results of Examples 1-8, in order to achieve the best color vividness and luminous effect, the ratio of the components in the outdoor photosensitive material provided by the present invention is preferably: the volume ratio of resin and diluent is 1:1.5, and the weight ratio of rare earth aluminate long afterglow luminous raw powder, automobile paint masterbatch, light stabilizer and ultraviolet absorber per liter of mixed liquid is 1:0.02:0.003:0.003.
