Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of preparation of high-light-transmittance resin materials, and in particular to a high-light-transmittance resin material, a preparation method thereof, and applications thereof. Background Art
[0002] To enable air conditioner panels to display more elements while maintaining a harmonious appearance while maintaining aesthetic appeal, existing panels typically integrate the display area directly within the panel. Traditional panel materials offer a light transmittance of only 4.5% to 7.5% at a thickness of 1.4mm, failing to meet the demand for a superior display appearance. This is because the refractive index deviation Δn between the rutile titanium dioxide used in the dyeing process for white panels and the HIPS substrate is 1.16, resulting in extremely low light transmittance and affecting the clarity of the display area within the panel.
[0003] To improve the light transmittance of the display area in air conditioner panels, existing solutions use zinc sulfide instead of titanium dioxide for dyeing. Although the refractive index deviation Δn between zinc sulfide and the base material HIPS is 0.77, it can achieve higher light transmittance than titanium dioxide. However, because the zinc sulfide particle size D50 is 0.53μm and the titanium dioxide particle size D50 is 0.38μm, that is, the zinc sulfide particle size is even larger than the titanium dioxide particle size. With the reference of visible light yellow-green light λ being 0.55μm, and the zinc sulfide particle D50 ≈ visible light yellow-green light λ, the light transmittance of the air conditioner panel formed by zinc sulfide material is dominated by Mie scattering. The Mie scattering intensity is high, the diffuse transmission ratio is high, and the fogging phenomenon is obvious. This makes the display area of the air conditioner panel have rough edges when displaying patterns or characters, affecting the display effect. Summary of the Invention
[0004] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide a highly light-transmitting resin material, which can prevent the aggregation of color powder particles to form agglomerates through the formation of a double electric layer and the formation of steric hindrance, so that the agglomerated color powder particles are dispersed, thereby restoring the true particle size of the color powder, effectively reducing the particle size of the color powder, ensuring that the color powder in the resin material can stably maintain the true particle size and be evenly distributed, thereby increasing the proportion of Rayleigh scattering, effectively eliminating the fogging phenomenon, and improving display clarity.
[0005] A highly light-transmittant resin material comprises the following components in parts by weight: 100 parts of a base resin, 0.8-2 parts of a color powder, 0.4-0.8 parts of an alkyl ammonium salt, 0.2-0.5 parts of a light stabilizer, 0.2-0.5 parts of an ultraviolet absorber, 0.1-0.4 parts of a primary antioxidant, 0.1-0.4 parts of a secondary antioxidant, and 0.5-1 parts of a lubricant.
[0006] In a preferred technical solution of the present invention, the base resin is polystyrene. The base resin is a commonly used base material for air conditioner panels, taking into account factors such as comprehensive physical properties, glossiness, light transmittance, and cost.
[0007] In a preferred technical solution of the present invention, the color powder comprises at least one of titanium dioxide and zinc sulfide. The color powder is mainly used to adjust the light transmittance and whiteness of the material.
[0008] In a preferred technical solution of the present invention, the alkylammonium salt is at least one of cetyltrimethylammonium bromide, octadecyltrimethylammonium chloride, and dioctadecyldimethylammonium chloride.
[0009] Alkyl ammonium salts are used to treat toner particles, dissociating the agglomerates formed between them and restoring the particles to their true size. This improves light transmittance, reduces Mie scattering intensity, and enhances display clarity.
[0010] In a preferred technical solution of the present invention, the primary antioxidant is pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate].
[0011] In a preferred embodiment of the present invention, the secondary antioxidant is (2,4-di-tert-butylphenyl) phosphite triester. The primary and secondary antioxidants are used to provide aging resistance during processing. The primary antioxidant binds to active free radicals generated during processing to form hydroperoxides, while the secondary antioxidant promotes the decomposition of the hydroperoxides. The resulting small molecules are then pumped away by a vacuum pump.
[0012] The function of light stabilizers and ultraviolet absorbers is to ensure the long-term aging resistance of the air-conditioning panel, and to ensure that the air-conditioning remains white and does not turn yellow or age after years of use.
[0013] In a preferred technical solution of the present invention, the lubricant is ethylene bisstearamide. The lubricant can improve the fluidity of the product during the plastic extrusion process and improve the demoulding properties of the product during the injection molding stage.
[0014] A second object of the present application is to provide a method for preparing a highly light-transmitting resin material, comprising:
[0015] Weigh 100 parts of base resin, 0.8-2 parts of color powder, 0.4-0.8 parts of alkyl ammonium salt, 0.2-0.5 parts of light stabilizer, 0.2-0.5 parts of ultraviolet absorber, 0.1-0.4 parts of primary antioxidant, 0.1-0.4 parts of secondary antioxidant, and 0.5-1 parts of lubricant, and mix them evenly to form a first composition;
[0016] The first composition is fed into a screw extruder to obtain the highly light-transmitting resin material.
[0017] In a preferred technical solution of the present invention, the screw extruder is a twin-screw extruder, and the temperature zones of the twin-screw extruder are set as follows: zone 1 180°C, zone 2 200°C, zone 3 200°C, zone 4 200°C, zone 5 190°C, zone 6 195°C, zone 7 200°C, zone 8 200°C, and die head 200°C.
[0018] The third object of the present application is to provide an application of a highly light-transmittance resin material, wherein the highly light-transmittance resin material as described above is used to form an air-conditioning panel, which includes a display area.
[0019] The beneficial effects of the present invention are:
[0020] The present invention provides a highly light-transmitting resin material, which has an alkyl ammonium salt added thereto. The alkyl ammonium salt contains amino cations, and the amino cations in the alkyl ammonium salt are adsorbed on the surface of negatively charged toner particles to form a double electric layer, which makes the toner particles externally positively charged, increases electrostatic repulsion to form an electrostatic stabilization effect, and the extension of the long chain in the alkyl ammonium salt can promote the toner particles to form an effective steric stabilization effect. Through the formation of the double electric layer and the formation of steric hindrance, the toner particles can be prevented from agglomerating to form agglomerates, so that the agglomerated toner particles are dispersed, thereby restoring the true particle size of the toner, effectively reducing the particle size of the toner, and ensuring that the toner in the resin material can stably maintain the true particle size and be evenly distributed. When the resin material is light-transmitting, the diffuse transmission ratio of light caused by scattering is positively correlated with the diameter of the toner particles in the substrate. Reducing the particle diameter can effectively reduce scattered light, increase the proportion of Rayleigh scattering, effectively eliminate fogging, and improve display clarity.
[0021] The present application provides a method for preparing a highly transparent resin material. The method comprises weighing the above components and then mixing them uniformly to form a first composition; and feeding the first composition into a screw extruder to obtain the highly transparent resin material. During the melt extrusion process of the material, the cations of the alkylammonium salt adsorb on the surface of the negatively charged toner particles, forming a double electric layer. The outer layer is positively charged, increasing electrostatic repulsion and forming an electrostatic stabilization effect. The extension of the long alkyl chain promotes the formation of effective steric stabilization of the toner particles. Through the electrostatic steric stabilization mechanism, the agglomerates formed by the aggregation of toner ions are dissociated, effectively restoring the true particle size of the particles, reducing the Mie scattering intensity, and improving the display performance of the material.
[0022] A highly transmissive resin material provided in the present application is used to form an air-conditioning panel. The highly transmissive resin material can prevent the aggregation of color powder particles to form agglomerates through the formation of a double electric layer and the formation of steric hindrance, so that the agglomerated color powder particles are dispersed, thereby restoring the true particle size of the color powder, effectively reducing the particle size of the color powder, and ensuring that the color powder in the resin material can stably maintain the true particle size and be evenly distributed. The reduction in particle diameter can effectively reduce scattered light, increase the proportion of Rayleigh scattering, and effectively eliminate the fogging phenomenon, providing possibilities for the diversification and refinement of the display effects of the air-conditioning panel. BRIEF DESCRIPTION OF THE DRAWINGS
[0023] Figure 1 This is a schematic flow chart of a method for preparing a highly light-transmittance resin material in an embodiment of the present application. DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.
[0025] The terms used in this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The singular forms "a," "the," and "the" used in this invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.
[0026] It should be understood that although the terms "first", "second", "third", etc. may be used to describe various information in the present invention, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise clearly and specifically defined.
[0027] Smaller particles have higher surface energy and larger specific surface area, making them more likely to adsorb to each other and form agglomerates. The highly light-transmittance resin material proposed in the present invention, when used in combination with an alkyl ammonium salt, can promote the dissociation and dispersion of agglomerates, thereby restoring the true particle size of the toner particles. Specifically, the D50 of zinc sulfide particles can be reduced from 0.53 μm to below 0.35 μm, and the D50 of titanium dioxide particles can be reduced from 0.38 μm to below 0.25 μm. During the twin-screw melt extrusion process, the titanium dioxide and zinc sulfide particles stably maintain their true particle size and are evenly distributed.
[0028] With the reference wavelength of visible yellow-green light being 0.55μm, if the toner particle size is approximately λ, the panel will be primarily Mie scattering, resulting in high scattering intensity, a high diffuse transmittance ratio, and noticeable fogging. If the toner particle size is approximately λ / 2, i.e., half the wavelength of visible light, light becomes easily transmitted, and the scattering intensity decreases significantly, resulting in a state where Mie scattering is dominant and Rayleigh scattering is supplementary. If the toner particle size is approximately λ / 4, Rayleigh scattering becomes dominant, significantly improving light transmittance. Many translucent materials require filler particles with a size of less than 0.1μm.
[0029] Because the toner particles have a uniform particle size distribution, the alkylammonium salts used in this application can effectively reduce the particle size D50 of the toner ions, significantly increasing the proportion of particles with a distribution range below 0.2μm. This translates to approximately 20% being easily light-transmissive and non-diffuse. Compared to existing air conditioning panel structures, the whiteness achieved with the same amount of toner added by weight is the same, but both light transmittance and display quality are improved.
[0030] The present application provides a highly light-transmitting resin material comprising the following components in parts by weight:
[0031]
[0032] The base resin in this application is HIPS. The base resin takes into account comprehensive physical properties, glossiness, light transmittance, cost and other factors, and is a commonly used base material for air conditioning panel materials.
[0033] Color powder is mainly used to adjust the light transmittance and whiteness of the material. Color powder contains one or both of titanium dioxide and zinc sulfide.
[0034] Alkyl ammonium salts are used to treat toner particles, dissociating aggregates and restoring their true size. This improves light transmittance, reduces Mie scattering intensity, and enhances display clarity. The alkyl ammonium salt is at least one of cetyltrimethylammonium bromide, octadecyltrimethylammonium chloride, and dioctadecyldimethylammonium chloride.
[0035] The function of light stabilizers and ultraviolet absorbers is to ensure the long-term aging resistance of the air-conditioning panel, and to ensure that the air-conditioning remains white and does not turn yellow or age after years of use.
[0036] The primary antioxidant and the secondary antioxidant are used for anti-aging in the processing process. The primary antioxidant can combine with the active free radicals generated in the processing process to generate hydroperoxides, while the secondary antioxidant promotes the decomposition of hydroperoxides. The small molecules generated are finally pumped away by the vacuum pump.
[0037] Lubricants can improve product flow during the plastic extrusion process and enhance product release during the injection molding process. Specifically, lubricants can be ethylene bisstearamide, or EBS for short.
[0038] The proportion of diffuse light transmitted due to scattering when the material is transmissive is positively correlated with the diameter of the toner particles in the substrate. Whether the scattering type is dominated by Rayleigh scattering or Mie scattering is also closely related to the particle diameter. Reducing the particle diameter can effectively reduce scattered light and increase the proportion of Rayleigh scattering. Reducing the particle diameter can effectively eliminate the fogging phenomenon.
[0039] The highly light-transmitting resin material provided by the present application has an alkyl ammonium salt added thereto, which contains amino cations. The amino cations in the alkyl ammonium salt are adsorbed on the surface of the negatively charged toner particles to form a double electric layer, which makes the toner particles positively charged on the outside, increases electrostatic repulsion and forms an electrostatic stabilization effect, and the extension of the long chain in the alkyl ammonium salt can promote the toner particles to form an effective steric stabilization effect; through the formation of the double electric layer and the formation of steric hindrance, it is possible to prevent the toner particles from agglomerating to form agglomerates, so that the agglomerated toner particles are dispersed, thereby restoring the true particle size of the toner, effectively reducing the particle size of the toner, and ensuring that the toner in the resin material can stably maintain the true particle size and be evenly distributed. When the resin material is light-transmitting, the diffuse transmission ratio of light caused by scattering is positively correlated with the diameter of the toner particles in the substrate. Reducing the particle diameter can effectively reduce scattered light, increase the proportion of Rayleigh scattering, effectively eliminate fogging, and improve display clarity.
[0040] The present application provides a method for preparing a highly transparent resin material, such as Figure 1 As shown, including:
[0041] S1: Weighing the base resin, color powder, alkyl ammonium salt, light stabilizer, ultraviolet absorber, primary antioxidant, secondary antioxidant, and lubricant in parts by weight to form a first composition;
[0042] S2: Add the first composition to a high-speed mixer and mix uniformly; the parameters of the high-speed mixer are as follows: at room temperature, mix for 2 minutes, and a speed of 1000 rad / min. After the materials are mixed, take them out for processing;
[0043] S3: Set the temperature of the twin-screw extruder. The temperature zones of the twin-screw are set as follows: zone 1 180°C, zone 2 200°C, zone 3 200°C, zone 4 200°C, zone 5 190°C, zone 6 195°C, zone 7 200°C, zone 8 200°C, and die head 200°C.
[0044] S4: adding the first mixture to a twin-screw extruder for processing; specifically, after the temperature of the twin-screw extruder is stabilized, the equipment is turned on and cleaned, and then the evenly mixed first composition is added to the main feed, the twin-screw speed, feeding speed and water flow length are adjusted, and the mixture is pelletized by a pelletizer to prepare a highly light-transmittance resin material.
[0045] S5: Add the resin material into the injection molding machine for injection molding.
[0046] In the present application, the above components are weighed and mixed uniformly to form a first composition; the first composition is then fed into a screw extruder to obtain the highly transparent resin material. During the melt extrusion process, the cations of the alkylammonium salt adsorb onto the surface of the negatively charged toner particles, forming a double layer. The outer layer becomes positively charged, increasing electrostatic repulsion and forming an electrostatic stabilization effect. The extension of the long alkyl chain promotes effective steric stabilization of the toner particles. Through the electrostatic steric stabilization mechanism, the agglomerates formed by the aggregation of toner ions are dissociated, effectively restoring the true particle size of the particles, reducing the Mie scattering intensity, and improving the material's display performance.
[0047] The present application also provides an application of a highly transparent resin material for forming an air-conditioning panel, wherein the air-conditioning panel includes a display area. Specifically, the resin material output from the twin-screw extruder is added to an injection molding machine for injection molding to obtain an air-conditioning panel. The present application provides a highly transparent resin material for forming an air-conditioning panel. The highly transparent resin material can avoid the aggregation of color powder particles to form agglomerates through the formation of a double electric layer and the formation of steric hindrance, so that the agglomerated color powder particles are dispersed, thereby restoring the true particle size of the color powder, effectively reducing the particle size of the color powder, and ensuring that the color powder in the resin material can stably maintain the true particle size and be evenly distributed. The reduction in particle diameter can effectively reduce scattered light, increase the proportion of Rayleigh scattering, and effectively eliminate the fogging phenomenon, providing possibilities for the diversification and refinement of the display effect of the air-conditioning panel.

[0180] The conclusions of the above tests are shown in Table 2.
[0181] Table 2 Test results of air conditioning panels in the embodiments and comparative examples
[0182]
[0183] From the comparison between Example 1 and Comparative Example 1, it can be seen that when the color powder is only titanium dioxide, the absence of the addition of alkyl ammonium salt in Comparative Example 1 will reduce the transmittance of the resin material, while the addition of alkyl ammonium salt in Example 1 will effectively improve the transmittance of the resin material.
[0184] Comparison of Example 4 and Comparative Example 4 shows that when the toner is solely zinc sulfide, the absence of an alkyl ammonium salt in Comparative Example 4 results in noticeable haloing and frayed edges on the digital images observed on the panel. This is because the zinc sulfide particle size is larger than that of the titanium dioxide, increasing the degree of Mie scattering. Adding an alkyl ammonium salt to the resin material in Example 4 results in a clearer display.
[0185] By comparing Example 2, Example 3 with Comparative Example 2, Comparative Example 3, it can be seen that: when the color powder is a mixture of titanium dioxide and zinc sulfide, the absence of alkyl ammonium salt in Comparative Example 2 and Comparative Example 3 will cause the digital halo observed on the panel to be obvious, with burrs, and relatively low transmittance; while the resin material after adding alkyl ammonium salt in the present application has a higher transmittance and a clearer display effect.
[0186] A comparative analysis of Examples 1 to 8 and Comparative Examples 1 to 4 revealed that the introduction of 0.4 to 0.8 parts of alkylammonium salt CTAB promoted the formation of a deflocculated state in the toner particles, restored the true particle size, significantly reduced the average D50 of the toner particles, reduced the diffuse light ratio, and achieved a high-quality display effect. Alkylammonium salt CTAB belongs to a cationic quaternary ammonium surfactant, cetyltrimethylammonium bromide. The amino cations of the alkylammonium salt adsorb on the surface of the negatively charged particles, forming a double layer, with a positive external charge, increasing electrostatic repulsion to form an electrostatic stabilization effect, while the extension of the alkyl long chain can promote the formation of effective steric stabilization of the particles. Through these two mechanisms, the agglomerates are dissociated and the agglomerated particles are dispersed. Using a laser particle size analyzer to compare and analyze zinc sulfide before and after the addition of CTAB, the particle size D50 was reduced from 0.53 μm to 0.30 μm.
[0187] Taking visible yellow-green light as an example, λ is 0.55μm. When the toner particle size is approximately λ, Mie scattering is dominant, resulting in high scattering intensity, a high diffuse transmittance, and noticeable fogging. When the toner particle size is approximately λ / 2, reaching half the wavelength of visible light, light becomes readily transmitted, and the scattering intensity decreases significantly, resulting in a state where Mie scattering is dominant and Rayleigh scattering is secondary. When the toner particle size is approximately λ / 4, Rayleigh scattering becomes dominant, significantly improving light transmittance. Therefore, many translucent materials require particle sizes below 0.1μm. Because particle sizes are distributed within a certain range, as the particle size D50 decreases, while the D50 still falls short of reaching half the wavelength, the proportion of particles falling below 0.2μm increases significantly compared to materials without the addition of alkylammonium salts. This translates to approximately 20% of the particles being readily transmissive and not diffusely transmitted. Therefore, even with the same weight of toner added, the whiteness of the air conditioner panel remains the same, but both light transmittance and display quality are improved.
[0188] By comparing and analyzing Examples 1 to 4, and Comparative Examples 1 to 4, it can be seen that the introduction of 0.4 to 0.8 parts of alkylammonium salt CTAB does not affect the tensile strength, flexural strength, flexural modulus and Izod notched impact strength of the resin material, that is, it does not lead to a significant reduction in the physical properties of the air-conditioning panel, and can still meet the performance requirements of the air-conditioning panel.
[0189] At the same time, the introduction of 0.4 to 0.8 parts of alkylammonium salt CTAB will slightly reduce the whiteness of the resin material, but it can be adjusted to meet the material color requirements by color adjustment.
[0190] A comparative analysis of Examples 1 to 8 and Comparative Examples 5 to 8 revealed that the addition of 0.4 to 0.8 parts of alkylammonium salt CTAB was effective. However, adding 1.2 parts of alkylammonium salt CTAB did not further improve light transmittance and display quality, but instead increased costs, reduced the whiteness of the air conditioner panel, increased the difficulty of color matching, and affected the stability of the air conditioner panel formulation.
[0191] By comparing and analyzing Examples 1 to 8, and Comparative Examples 1 to 8, it can be seen that when the light transmittance of the resin material is increased to close to 20%, the internal structure of the air-conditioning panel will not be exposed under indoor light, that is, it has good structural concealment and excellent display effect.
[0192] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures. In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0193] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0194] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components.
