Description

Technical Field

[0001] The present application relates to the field of material processing, and more specifically, to a feather sheet material for simulating an animal and a preparation method thereof. Background Art

[0002] The production technology of simulated animals has been widely used and developed in recent years, especially in the fields of entertainment, decoration and gardening. Lifelike simulated animal models can bring a more realistic and vivid viewing experience. With the advancement of technology and the increasing demand for environmental beautification, the market demand for highly realistic and durable simulated animal products is growing. However, the feathers of simulated animals are a complex technical link, which needs to meet the technical requirements of presenting realistic effects under different light conditions, which is crucial to improving the overall quality of simulated animals.

[0003] In the prior art, in order to achieve the realistic effect of simulated animal feathers, different inks are usually applied on the surface of the substrate to form different light-shielding effects. These technical means mainly include: (1) using a single layer of ink to simulate the gloss of feathers through different colors and glossiness; (2) using multi-layer ink coating technology to achieve different transparency and reflection effects through the superposition of different coatings. However, although these solutions can improve the visual effect of feathers to a certain extent, it is difficult to achieve the transparent and realistic effect of feathers under complex lighting conditions.

[0004] Although the above-mentioned methods in the prior art can improve the realism of feathers to a certain extent, there are still certain defects in the actual application process. For example, in terms of simulating the transparent effect of feathers, most of the current technologies cannot achieve fine control of light transmission and light blocking, resulting in the product's effect under light not being realistic enough. In addition, the current simulated animals are prone to falling off or dimming during long-term use, affecting the overall beauty and durability of the simulated animals, and further research is needed for this. Summary of the invention

[0005] In order to achieve better translucency and realistic effects while reducing the possibility of shedding and maintaining better gloss and durability, the present application provides a simulated animal feather sheet and a preparation method thereof.

[0006] In a first aspect, the present application provides a simulated animal feather sheet, comprising a substrate, characterized in that the surface of the substrate comprises at least one light-transmitting area, a semi-transmitting area and a light-shielding area, each of the light-transmitting areas is provided with an ink base layer and a light-transmitting ink layer, each of the light-shielding areas is provided with an ink base layer and a light-shielding ink layer, the semi-transmitting areas are provided with an ink base layer, a light-shielding ink layer and a light-transmitting ink layer in sequence, and each of the ink base layers is connected to the surface of the substrate; the thickness of the light-transmitting ink layer in the light-transmitting area is greater than the thickness of the light-transmitting ink layer in the semi-transmitting area, and the thickness of the light-shielding ink layer in the light-shielding area is greater than the thickness of the light-shielding ink layer in the semi-transmitting area; The light-shielding ink layer is formed by coating and curing an organosilicon-modified polyurethane acrylate light-shielding ink, the light-transmitting ink layer is formed by coating and curing an organosilicon-modified polyurethane acrylate light-transmitting ink, and the ink base layer is obtained by coating and curing an organosilicon-modified polyurethane acrylate ink.

[0007] The above technical scheme realizes different shading effects in the light-transmitting area, the semi-transmitting area and the light-shielding area through the layer structure setting of the light-transmitting area, the semi-transmitting area and the light-shielding area, and the different thicknesses of the light-transmitting ink layer or the light-shielding ink layer formed, and cooperates with each other to form a feather sheet material to achieve a bright and realistic visual effect in a light-transmitting environment.

[0008] The ink produced by silicone-modified polyurethane acrylate has excellent weather resistance and adhesion stability, making the ink layers in each area more closely matched. Under light irradiation, the light-transmitting area shows higher transparency, and combined with the filler, the light-shielding area shows better light-shielding performance. The light-transmitting area has a brightness between the two, making the overall appearance of feathers more natural and realistic. When feathers are used to produce simulated animals, they have better simulation effects and durability.

[0009] In summary, the present application controls various ink layers to form light-transmitting areas, semi-transmitting areas and light-shielding areas to achieve different transparent and light-shielding effects, and makes them cooperate with each other to achieve a transparent and real visual effect of the feather sheet in a light-transmitting environment; and the various light-shielding inks produced by silicone-modified polyurethane acrylate make the formed ink layer structure stable, with good adhesion and weather resistance, etc., reduce the phenomenon of falling off after long-term use, and maintain better transparency and gloss effects.

[0010] Preferably, the organosilicon-modified polyurethane acrylate shading ink is obtained by mixing an organosilicon-modified polyurethane acrylate prepolymer and a shading powder; the organosilicon-modified polyurethane acrylate light-transmitting ink is obtained by mixing an organosilicon-modified polyurethane acrylate prepolymer and a light-transmitting powder; the organosilicon-modified polyurethane acrylate ink is coated with an organosilicon-modified polyurethane acrylate prepolymer.

[0011] By adopting the above technical scheme, the silicone-modified polyurethane acrylate prepolymer has better light transmittance, adhesion and weather resistance. When used in combination with shading powder and translucent powder, the shading area, semi-transparent area and translucent area can achieve better light shading and light transmission effects respectively, thereby enhancing the visual effect of the feather sheet in a light environment. The feather sheet used in simulated animals shows a bright and realistic effect under different light conditions, and has better weather resistance and water resistance, thereby reducing the possibility of falling off and dimming during long-term use.

[0012] Preferably, the light-shielding powder is composed of color powder and light-shielding filler, and the light-transmitting powder is composed of color powder and light-transmitting filler.

[0013] By combining the color powder with the shading filler or the translucent filler, the shading area, the semi-translucent area and the translucent area can achieve different shading and translucent effects, making the feathers of the simulated animals more realistic and translucent.

[0014] Preferably, the light-shielding filler is composed of multiple types of graphite, carbon black, talcum powder, and ceramic powder; the light-transmitting filler is composed of multiple types of silicate glass powder, SiO2 microcrystals, oyster shell powder, and jade powder.

[0015] The above fillers can be used in combination with colorants to achieve the shading and light-transmitting effects of the shading area, semi-transparent area, and light-transmitting area. Specifically, silicate glass powder and SiO2 microcrystals have better light-transmitting effects, and oyster shell powder and jade powder are used to make the light-transmitting area more transparent in a light environment. When graphite, carbon black, talcum powder, and ceramic powder are compounded, the shading area can have a higher light-shielding effect, and even in a strong light environment, it can play a better light-shielding role, thus forming a sharp contrast with the light-transmitting area, and then cooperate with each other, so that the feather sheet is more realistic.

[0016] Silicate glass powder is obtained by crushing silicate glass. Silicate glass refers to glass containing soda-lime silicate, sodium aluminum silicate, and sodium borosilicate. The density of the silicate glass powder of the present application is preferably 2.45-2.85 g / cm 3 , Mohs hardness 7.04-8.004. The main components of ceramic powder are aluminum oxide, silicon oxide, sodium oxide, calcium oxide, etc., Mohs hardness 7-8, density 2.41-2.93g / cm 3 .

[0017] Preferably, the light-shielding filler is composed of graphite, carbon black, talcum powder, and ceramic powder; the light-transmitting filler is composed of silicate glass powder, SiO2 microcrystals, oyster shell powder, and jade powder.

[0018] When light-shielding fillers made of graphite, carbon black, talcum powder, and ceramic powder are used; and light-transmitting fillers made of silicate glass powder, SiO2 microcrystals, oyster shell powder, and jade powder are used, the possibility of each ink layer falling off can be reduced, and at the same time, the overall feathers have better gloss and wear resistance, and are more transparent under light.

[0019] Preferably, the organosilicon-modified polyurethane acrylate prepolymer is composed of the following raw materials in weight percentage: Polyurethane acrylate 45-65% Silicone dispersant 10-30% Initiator 1-3% The balance is active diluent.

[0020] In the above scheme, the organosilicon dispersant can improve the dispersibility of the shading powder and the light-transmitting powder, improve their compatibility in the ink raw material system, and make the overall layer structure stable after curing. In addition, the organosilicon dispersant can further react with the polyurethane acrylate under the action of the initiator to further improve the adhesion and weather resistance, while the active diluent can also participate in the reaction of the raw material system while playing a dilution role, so that the ink formed by the organosilicon-modified polyurethane acrylate prepolymer has stable adhesion and good weather resistance after curing.

[0021] In summary, the silicone-modified polyurethane acrylate prepolymer forms a stable ink layer through a reasonable ratio of polyurethane acrylate, silicone dispersant, initiator and active diluent, which improves the dispersion effect, adhesion and weather resistance of the ink layer, so that the feather sheet maintains a transparent and realistic effect during long-term use, and reduces the possibility of falling off and dulling.

[0022] Preferably, the organosilicon dispersant is prepared from the following raw materials in percentage by weight: Polyethylene oxide-polypropylene oxide-polyethylene oxide block copolymer 10-22% Polydimethylsiloxane-poly 6-4-cyanobiphenyl-4-oxy-hexyl methacrylate 13-18% Methacrylate mono-terminated dimethyl polysiloxane 16-28% The balance was 1,3-bis(3-methacryloxypropyl)tetrakis(trimethylsiloxy)disiloxane.

[0023] Preferably, the organosilicon dispersant is prepared by the following method: According to weight percentage, polyethylene oxide-polypropylene oxide-polyethylene oxide block copolymer, polydimethylsiloxane-poly 6-4-cyanobiphenyl-4-oxy-hexyl methacrylate, methacrylate mono-terminated dimethylpolysiloxane, and 1,3-bis(3-methacryloxypropyl)tetrakis(trimethylsiloxy)disiloxane were weighed and mixed evenly to obtain an organosilicon dispersant.

[0024] By adopting the above technical solution, the adhesion and stability of the ink are improved, ensuring that the ink can be firmly attached to the substrate during the printing process and is not easy to fall off or discolor. Specifically, the polyethylene oxide-polypropylene oxide-polyethylene oxide block copolymer improves the flatness and glossiness of the coating film, and effectively disperses the pigments and fillers to prevent their agglomeration and sedimentation, thereby improving the uniformity and stability of the coating. The addition of polydimethylsiloxane-poly 6-4-cyanobiphenyl-4-oxy-methacrylate further enhances the adhesion and stability of the ink.

[0025] 1,3-Bis(3-methacryloxypropyl)tetrakis(trimethylsiloxy)disiloxane improves adhesion and plays a coupling role, thereby improving the dispersibility and compatibility of shading powder and light-transmitting powder. In combination with polyethylene oxide-polypropylene oxide-polyethylene oxide block copolymer, polydimethylsiloxane-poly 6-4-cyanobiphenyl-4-oxy-methacrylate hexyl, and methacrylate mono-terminated dimethylpolysiloxane, the obtained silicone dispersant has better dispersion, weather resistance and adhesion effects. The active groups therein further react with polyurethane acrylate and active diluents, so that the obtained ink layer has stable adhesion, good gloss and good weather resistance.

[0026] In summary, the use of 1,3-bis(3-methacryloxypropyl)tetrakis(trimethylsiloxy)disiloxane, polyethylene oxide-polypropylene oxide-polyethylene oxide block copolymer, polydimethylsiloxane-poly 6-4-cyanobiphenyl-4-oxy-hexyl methacrylate, and methacrylate mono-terminated dimethylpolysiloxane has a better synergistic effect and synergistic effect, further improving the adhesion stability, glossiness, and weather resistance of the ink layer formed on the feather sheet. The prepared simulated animal feathers can be more transparent under light, and when used for a long time in the wild, gardens, etc., they can ensure better glossiness and reduce the possibility of shedding. Improve its practicality.

[0027] Preferably, the activated diluent is one or more of THFA, IBOA and NVP.

[0028] By adopting the above technical scheme, the silicone-modified polyurethane acrylate prepolymer can better exert its characteristics. Selecting THFA, IBOA and NVP as activating diluents can not only effectively adjust the viscosity of the ink layer, but also promote full reaction with other ingredients, thereby ensuring that the formed ink layer is more stable and uniform, and improving the durability and visual effect of the entire feather sheet.

[0029] Preferably, the initiator is one or more of BPO, HMPP and IPP.

[0030] By adopting the above technical solution, the feather sheet of simulated animals is more transparent and realistic under light, and has better weather resistance, reducing the possibility of shedding and dimming. Among them, the initiator is composed of one or more of BPO, HMPP, and IPP, which ensures that the ink reacts more stably during the curing process and improves the overall performance of the feather sheet.

[0031] In a second aspect, the present application provides a method for preparing a feather sheet of a simulated animal, comprising the following steps: 1) applying the organosilicon-modified polyurethane acrylate ink on the surface of the substrate to form an ink base layer on the surface of the substrate; 2) applying the organosilicon-modified polyurethane acrylate light-shielding ink on the surface of the ink base layer, and then applying the organosilicon-modified polyurethane acrylate light-transmitting ink on the surface of the remaining ink base layer, and curing, so that at least one light-transmitting area, a semi-transmitting area and a light-shielding area are formed on the surface of the substrate to obtain a feather sheet.

[0032] The preparation method can ensure that light-transmitting areas, semi-light areas and light-shielding areas with different light-shielding effects are formed on the surface of the substrate. Specifically, the organic silicon-modified polyurethane acrylate ink is applied to the surface of the substrate to form an ink base layer, and then the light-shielding ink and the light-transmitting ink are applied and cured respectively, so that the feather sheet shows a realistic translucent effect under light. Among them, the ink base layer with a humidity controlled at 33-45% improves the uniformity and stability of the coating, thereby improving the weather resistance and service life of the final feather sheet.

[0033] In summary, this application has the following beneficial effects: 1. The present application controls various ink layers to form light-transmitting areas, semi-transmitting areas and light-shielding areas to achieve different transparent and light-shielding effects, and cooperates with each other to achieve a transparent and real visual effect of the feather sheet in a light-transmitting environment; and the various light-shielding inks produced by silicone-modified polyurethane acrylate make the ink layer structure stable, with good adhesion and weather resistance, etc., reduce the phenomenon of shedding after long-term use, and maintain better transparency and gloss effects.

[0034] 2. By using light-shielding fillers composed of graphite, carbon black, talcum powder, and ceramic powder; and light-transmitting fillers composed of silicate glass powder, SiO2 microcrystals, oyster shell powder, and jade powder, the possibility of each ink layer falling off can be reduced, and at the same time, the overall feather has a better gloss and is more transparent under light.

[0035] 3. Silicone-modified polyurethane acrylate prepolymer forms a stable ink layer through a reasonable ratio of polyurethane acrylate, silicone dispersant, initiator and active diluent, which improves the dispersion effect, adhesion and weather resistance of the ink layer, so that the feather sheet can maintain a transparent and realistic effect during long-term use, and reduce the possibility of falling off and dulling.

Make the feathers of the simulated animals more transparent under light, and when used in the wild, gardens, etc. for a long time, it can ensure better glossiness and reduce the possibility of shedding. Improve its practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Glossiness: glossiness tester was used for testing, the incident angle of light was 60°, the testing standard was based on GB / T9754-2007, and the light-transmitting area, semi-transmitting area and light-shielding area on the feather sheets obtained in Examples 2-10 and Comparative Example 1 were tested respectively.

[0065] Transmittance: With reference to GB / T2410-2008, the light incident angle is 60°, and the transmittance under light intensity of 2500Lux and 12000Lux is tested by a spectrophotometer, and the light-transmitting area, semi-transmitting area and light-shielding area on the feather sheet obtained in Examples 2, 5-6, 9-11 and Comparative Example 1 are detected respectively, and the transmittance change rate is calculated, which is equal to |(the transmittance when the light intensity is 12000Lux minus the transmittance when the light intensity is 2500Lux) / the transmittance when the light intensity is 12000Lux|*100%.

Therefore, it is shown that the ink produced by using the silicone-modified polyurethane acrylate of the present application has better weather resistance, and combined with the layer structure, the obtained feather sheet has a better simulation effect, and still maintains a better simulation effect under different light intensities.

[0068] Combining Example 2 and Example 5 and Table 1-2, it can be seen that the gloss and transmittance of Example 2 are both lower than those of Example 5, while the gloss change rate and transmittance change rate of Example 2 are both higher than those of Example 5, indicating that the light-shielding filler is composed of graphite, carbon black, talcum powder, and ceramic powder in a weight ratio of 1:0.3:1:1.5; the light-transmitting filler is composed of silicate glass powder, SiO2 microcrystals, oyster shell powder, and jade powder in a weight ratio of 0.2:1:1.2:1, which can enable the feather sheet to obtain better comprehensive performance and have better simulation effect when used on simulated animals.

[0069] Combining Example 5, Example 9-11 and Example 6 and Table 1-2, it can be seen that the gloss and transmittance of Example 5 and Example 9-11 are less than the gloss and transmittance of Example 6, while the gloss change rate and transmittance change rate of Example 5 and Example 9-11 are greater than the gloss change rate and transmittance change rate of Example 6, indicating that the use of polyethylene oxide-polypropylene oxide-polyethylene oxide block copolymer, polydimethylsiloxane-poly 6-4-cyanobiphenyl-4-oxy-methacrylate hexyl, methacrylate mono-terminated dimethylpolysiloxane, 1,3-bis(3-methacryloxypropyl)tetrakis(trimethylsiloxy)disiloxane as an organosilicon dispersant can achieve better dispersing effect, and further react with polyurethane acrylate to obtain the ink, which is used in the process of this application, and the feather sheet obtained has better comprehensive performance.
