Description

Technical Field

[0001] This invention relates to the field of membrane technology, and in particular to an organosilicon product. Background Technology

[0002] Silicone film is an innovative, environmentally friendly material that combines the superior properties of silicone with the texture of leather, offering a new option for modern industry and consumers. With its unique chemical structure and physical properties, this material provides an environmentally friendly and durable alternative, especially given the environmental and ethical challenges facing traditional animal and synthetic leathers today. Silicone film has a wide range of applications, from automotive interiors and furniture décor to electronic product exteriors and outdoor gear. With technological advancements and increasing consumer demand for environmentally friendly materials, silicone film is gradually becoming a popular choice in the market.

[0003] As people's living standards improve, their demands for furniture decoration are also gradually increasing. For example, people often print specific patterns on walls or wooden furniture surfaces to enhance the aesthetics of the room. However, current methods for printing patterns on walls or wooden furniture mostly involve carving patterns directly onto the surface or painting patterns with specific pigments. But patterns printed in this way are usually exposed, making them difficult to clean and maintain.

[0004] In view of this, the present invention proposes an organosilicon product that combines organosilicon leather to display printed patterns on wall or furniture surfaces. Summary of the Invention

[0005] The present invention aims to solve the above problems and provides an organosilicon product that can conveniently display patterns and is easy to clean and maintain.

[0006] To achieve the above objectives, the present invention provides an organosilicon product comprising a transparent organosilicon layer, a pattern-transparent layer, and a base layer stacked sequentially, wherein the pattern-transparent layer is made of transparent material such as PET, PVC, or acrylic, and the base layer has a specific texture or pattern on the side facing the pattern-transparent layer.

[0007] In this invention, PET, PVC or acrylic is used as the intermediate layer, on which a transparent silicone layer can be easily printed. By using the transparent silicone layer as the outermost layer, the silicone products can be easily cleaned and maintained by taking advantage of the silicone’s scratch-resistant, stain-resistant and hydrophobic properties. In addition, the transparent properties of silicone make it easy to clearly display the patterns on the base layer through the transparent silicone layer.

[0008] Optionally, the silicone product involved in this invention may also include an adhesive layer disposed between the patterned transparent layer and the base layer.

[0009] In the silicone products involved in this invention, the adhesive layer may optionally be PU and / or PUR hot melt adhesive.

[0010] In the organosilicon products involved in this invention, optionally, the transparent organosilicon layer includes at least one of silicone resin, silicone rubber, and fluorosilicone polymer.

[0011] In the organosilicon products involved in this invention, optionally, the silicone resin includes at least one of VMQ silicone resin, MQ silicone resin, and fluorosilicone resin. In this case, MQ silicone resin has excellent heat resistance and low temperature resistance, good weather resistance, good water repellency, good adhesion, and excellent isolation properties. Using MQ resin as the outermost layer can improve the heat resistance, low temperature resistance, weather resistance, water repellency, and isolation properties of the TPU composite film. VMQ silicone resin (vinyl MQ silicone resin) has excellent heat resistance, low temperature resistance, film-forming properties (able to form a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties. Using VMQ silicone resin as the outermost layer can improve the heat resistance, low temperature resistance, weather resistance, water repellency, and isolation properties of the TPU composite film. Fluorosilicone resin possesses excellent properties such as temperature resistance, film-forming ability (capable of forming a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties. It also exhibits superior high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency. Using fluorosilicone resin as the outermost layer can enhance the high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency of the TPU composite film. A mixture of two or three of these properties can combine the advantages of both.

[0012] In the silicone products involved in this invention, the base layer may optionally be a metal plate, wood plate, plastic plate, or engineered wood. This allows for the convenient fabrication of silicone products based on various types of wood plates, metal plates, engineered wood, etc., thereby enhancing the aesthetics and ease of cleaning and maintenance of various types of furniture and decorative items.

[0013] In the organosilicon products involved in this invention, optionally, the metal plate includes color steel plate and aluminum composite panel; the wood board includes solid wood multilayer board, OSB board, rubber board, wood veneer panel, bamboo fiber board; the plastic plate includes PVC board; and the artificial board includes melamine board, particleboard, chipboard, MDF, fireproof board, and eco-board.

[0014] In the organosilicon products involved in this invention, optionally, the transparent organosilicon layer contains aluminum hydroxide.

[0015] Optionally, the organosilicon products involved in this invention may also include a flame-retardant layer disposed between the patterned transparent layer and the base layer, the flame-retardant layer comprising an adhesive and a phosphorus-containing flame retardant.

[0016] In the silicone products involved in this invention, optionally, the transparent silicone layer includes a first silicone coating and a second silicone coating, wherein the first silicone coating is disposed on the side of the pattern-transparent layer away from the base layer, and the second silicone coating is disposed on the side of the first silicone coating away from the pattern-transparent layer.

[0017] Optionally, the organosilicon product involved in this invention may also include a third organosilicon coating, which is disposed on the side of the second organosilicon coating away from the first organosilicon coating.

[0018] In the silicone products involved in this invention, optionally, the patterned transparent layer includes a printed substrate and a pattern printed on the printed substrate in a predetermined manner.

[0019] In the organosilicon products involved in this invention, the predetermined method may optionally include screen printing, thermal transfer printing, or UV printing.

[0020] Optionally, the organosilicon product of the present invention may also include a tactile layer, which is disposed on the side of the transparent organosilicon layer away from the pattern-transmitting layer.

[0021] In the silicone products involved in this invention, optionally, the pattern is printed on the side of the printed substrate close to the base layer.

[0022] In the silicone products involved in this invention, optionally, an adhesive is provided between the silicone layer and the patterned transparent layer.

[0023] According to the present invention, an organosilicon product that is easy to print patterns on and easy to clean and maintain can be provided. Attached Figure Description

Obviously, the drawings in the description are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] Figure 1 This is a schematic diagram of the structure of the organosilicon product of Example 1 of the present invention.

[0026] Figure 2 This is a schematic diagram of the structure of the organosilicon product of Example 2 of the present invention.

[0027] Figure 3 This is a schematic diagram of the structure of the organosilicon product of Example 3 of the present invention. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the invention clearer, the technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without creative effort are within the scope of protection of the invention.

[0029] This invention provides an organosilicon product 1 (hereinafter sometimes simply referred to as organosilicon product 1). The organosilicon product 1 can be used in furniture, walls, etc. By printing patterns on the organosilicon product 1, the aesthetic performance of the furniture and walls can be improved, while making the organosilicon product 1 easy to clean and maintain.

[0030] In some embodiments, the silicone article 1 may include a transparent silicone layer 30, a patterned transparent layer 20, and a base layer 10 stacked sequentially.

[0031] In some embodiments, the pattern-transmitting layer is made of a transparent material such as PET, PVC, or acrylic.

[0032] In this invention, PET, PVC or acrylic is used as the intermediate layer, and a transparent silicone layer can be easily printed on it. By using the transparent silicone layer as the outermost layer, the silicone product 1 can be easily cleaned and maintained by taking advantage of the scratch-resistant, stain-resistant and hydrophobic properties of silicone. In addition, the transparent properties of silicone can make it easy to clearly display the pattern on the base layer through the transparent silicone layer.

[0033] In some embodiments, the silicone article 1 may further include an adhesive layer disposed between the patterned transparent layer 20 and the base layer 10.

[0034] In some embodiments, the adhesive layer can be PU and / or PUR hot melt adhesive. In other words, the adhesive layer can be PU (Polyurethane); the adhesive layer can be PUR hot melt adhesive (Polyurethane Reactive Hot Melt Adhesive); the adhesive layer can also include both PU and PUR hot melt adhesive. For example, the adhesive layer can be a layer of PU first coated on the patterned transparent layer 20, and then a layer of PUR hot melt adhesive coated on top of the PU. In this case, PU itself has certain adhesive properties, but PUR hot melt adhesive generally has higher adhesive strength, especially for some difficult-to-bond materials. Combining the two can make the bond stronger, improving the quality and durability of the product. Furthermore, the performance of PU materials at different temperatures is somewhat limited, while PUR hot melt adhesive has better temperature resistance and can maintain good adhesion over a wider temperature range. Using them together can broaden the product's operating temperature range, allowing it to maintain stable performance in high or low temperature environments. In addition, PU materials have good wear resistance and flexibility, while PUR hot melt adhesive can enhance the strength and stability of the bonded areas. The synergistic effect of both improves the overall performance of the product.

[0035] In some embodiments, the transparent silicone layer 30 may include at least one of silicone resin, silicone rubber, and fluorosilicone polymer.

[0036] In some embodiments, the silicone resin may include at least one of VMQ silicone resin, MQ silicone resin, and fluorosilicone resin. In this case, MQ silicone resin possesses excellent heat and low temperature resistance, good weather resistance, good water repellency, good adhesion, and excellent barrier properties. Using MQ resin as the outermost layer can enhance the heat resistance, low temperature resistance, weather resistance, water repellency, and barrier properties of the TPU composite film. VMQ silicone resin (vinyl MQ silicone resin) possesses excellent heat resistance, low temperature resistance, film-forming properties (capable of forming a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and barrier properties. Using VMQ silicone resin as the outermost layer can enhance the heat resistance, low temperature resistance, weather resistance, water repellency, and barrier properties of the TPU composite film. Fluorosilicone resin possesses excellent properties such as temperature resistance, film-forming ability (capable of forming a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties. It also exhibits superior high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency. Using fluorosilicone resin as the outermost layer can enhance the high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency of the TPU composite film. A mixture of two or three of these properties can combine the advantages of both.

[0037] In some embodiments, the base layer 10 can be a metal plate, wood plate, plastic plate, or engineered wood. This allows for the convenient fabrication of silicone products 1 based on various types of wood plates, metal plates, engineered wood, etc., thereby enhancing the aesthetics and ease of cleaning and maintenance of various types of furniture and decorative items.

[0038] In some embodiments, the metal sheet may include color-coated steel sheet or aluminum composite panel. The wood sheet may include plywood, OSB, rubberwood, wood veneer, or bamboo fiberboard. The plastic sheet may include PVC sheet. The engineered wood may include melamine board, particleboard, chipboard, MDF, fire-resistant board, or eco-board.

[0039] Wood panels, metal panels, and engineered wood panels typically have specific textures or patterns on their surfaces. However, when used as furniture or decorative items, they are usually exposed and prone to scratches. Furthermore, their surfaces lack waterproof and stain-resistant properties. This invention addresses this by providing a pattern-transparent layer 20 on the surface of a base layer 10, and then providing a transparent silicone layer 30 on top of the pattern-transparent layer 20. On one hand, the transparency of both the pattern-transparent layer 20 and the transparent silicone layer 30 allows the pattern on the base layer 10 to be clearly displayed. On the other hand, the excellent scratch-resistant, stain-resistant, and hydrophobic properties of the transparent silicone layer 30 facilitate cleaning and maintenance of the silicone product 1.

[0040] In some embodiments, the transparent silicone layer 30 may contain aluminum hydroxide. Aluminum hydroxide undergoes a decomposition reaction upon heating; this decomposition is endothermic, absorbing a large amount of heat and thus lowering the temperature of the combustion zone. Furthermore, aluminum hydroxide decomposes into water and aluminum oxide. The water vapor produced by the decomposition of aluminum hydroxide can dilute the concentration of flammable gases in the combustion zone, reducing the intensity of the combustion reaction. Simultaneously, the water vapor can carry away some heat, further lowering the temperature of the combustion zone. The resulting aluminum oxide is a stable substance that can form a dense protective film on the material surface. This protective film can isolate oxygen, preventing further contact between oxygen and the silicone material, thereby inhibiting the combustion reaction. Therefore, the flame-retardant properties of the silicone product 1 can be greatly improved.

[0041] Reference Figure 2 In some embodiments, the silicone article 1 may further include a flame retardant layer 40 disposed between the patterned transparent layer 20 and the base layer 10.

[0042] In some embodiments, the flame-retardant layer 40 may include an adhesive and a phosphorus-containing flame retardant. In other words, the flame-retardant layer may have both flame-retardant and adhesive functions, and can be directly bonded to the base layer 10 through the adhesive function of the flame-retardant layer without the need for an adhesive layer. Of course, an adhesive layer may be further provided between the flame-retardant layer 40 and the base layer 10 based on the presence of the flame-retardant layer 40. This can improve the bonding stability between the flame-retardant layer 40 and the base layer 10.

[0043] In some embodiments, the adhesive may be polyurethane, acrylic, or acrylic self-adhesive. Both have good adhesive properties. Additionally, the addition of a phosphorus-containing flame retardant to the polyurethane, acrylic, or acrylic self-adhesive can improve its flame retardant properties. The proportion of the phosphorus-containing flame retardant should be appropriate to avoid affecting the adhesive properties of the flame-retardant layer 10.

[0044] Furthermore, in this invention, since the phosphorus-containing flame retardant is placed in the flame retardant layer 10 which is isolated from the transparent organosilicon layer 30, the direct contact between the phosphorus-containing compound and the platinum catalyst in the organosilicon material can be avoided, thus preventing platinum catalyst poisoning.

[0045] In some embodiments, phosphorus-containing flame retardants may include at least one of red phosphorus, ammonium polyphosphate, phosphate esters (such as tricresyl phosphate, triethyl phosphate), and phosphorus heterocyclic compounds.

[0046] In some embodiments, an adhesive layer may be provided between the flame-retardant layer 40 and the base layer 10. This ensures that the flame-retardant layer 40 and the base layer 10 are firmly bonded together.

[0047] Reference Figure 3 In some embodiments, the transparent silicone layer 30 may include a first silicone coating 31 and a second silicone coating 32. The first silicone coating 31 may be disposed on the side of the pattern-transmitting layer 20 away from the base layer 10, and the second silicone coating 32 may be disposed on the side of the first silicone coating 31 away from the pattern-transmitting layer 20. Thus, by providing two silicone coatings, the color fastness of the pattern and the abrasion resistance of the silicone product 1 can be guaranteed.

[0048] In some embodiments, the silicone article 1 may further include a third silicone coating 33. The third silicone coating 33 may be disposed on the side of the second silicone coating 32 away from the first silicone coating 31. Thus, by providing three silicone coatings, the wear resistance of the silicone article 1 can be further improved.

[0049] In some embodiments, aluminum hydroxide may preferably be mixed in the first silicone coating 31 or the second silicone coating 32. This prevents the aluminum hydroxide from being exposed to the outer layer and decomposing due to heat.

[0050] In other embodiments, aluminum hydroxide may also be mixed into the third organosilicon coating 33.

[0051] In some embodiments, the pattern-transmitting layer 20 may further include a printing substrate and a pattern printed on the printing substrate in a predetermined manner. In other words, a pattern can be printed on the pattern-transmitting layer 20. PET, PVC, or acrylic are all materials on which patterns can be easily printed. In this case, the pattern can be printed directly on the printing substrate, where the substrate can be a plain wood board, plastic board, or artificial board, thereby improving the pattern display effect of the silicone product 1 in the same way.

[0052] In some embodiments, the predetermined method includes screen printing, heat transfer printing, and UV printing.

[0053] Reference Figure 3 In some embodiments, the silicone article 1 may further include a tactile layer 50. The tactile layer 50 may be disposed on the side of the transparent silicone layer 30 away from the pattern-transparent layer 20. In this case, by using the tactile layer 50 as the outermost layer of the silicone article 1, the user's tactile experience can be improved.

[0054] In some embodiments, the pattern may be printed on the side of the printing substrate closest to the base layer.

[0055] In some embodiments, an adhesive is provided between the silicone layer 30 and the pattern-transparent layer 20. This enhances the adhesion between the silicone layer 30 and the pattern-transparent layer 20.

[0056] In some embodiments, at least one of a mildew inhibitor and an antibacterial agent may be added to the transparent silicone layer 30. This enables the silicone product 1 and its products to have mildew-proof and antibacterial functions, reducing the growth of bacteria and other microorganisms and extending the product's lifespan.

[0057] In some embodiments, the antifungal agent may be an organosilicon quaternary ammonium salt antibacterial agent, dibutyltin dilaurate, organosilicon copper quaternary ammonium salt, etc.

[0058] In some embodiments, the antibacterial agent may be an organosilicon quaternary ammonium salt antibacterial agent. For example, dimethyloctadecyl[3-trimethoxysilylpropyl]ammonium chloride, dimethyloctadecyl[3-methyldimethoxysilylpropyl]ammonium chloride, dimethyloctadecyl[3-triethoxysilylpropyl]ammonium chloride, etc.

[0059] In some embodiments, the silicone rubber may include at least one of dimethyl silicone rubber, methyl vinyl silicone rubber, phenyl silicone rubber, or fluorosilicone rubber.

[0060] In some embodiments, the thickness of the pattern-through layer 20 can be from 50 micrometers to 400 micrometers.

[0061] In some embodiments, the thickness of the first transparent silicone layer 31 can be from 10 micrometers to 300 micrometers.

[0062] In some embodiments, the thickness of the second transparent silicone layer 32 can be from 50 micrometers to 500 micrometers.

[0063] In some embodiments, the thickness of the third transparent silicone layer 33 can be from 10 micrometers to 200 micrometers.

[0064] In some embodiments, the silicone layer 30 may contain a hydrophobic agent, a scratch-resistant agent, a UV-resistant agent, and a weather-resistant agent. In this case, the hydrophobic agent can improve the hydrophobic properties of the silicone product 1, the scratch-resistant agent can improve the scratch resistance of the silicone product 1, the UV-resistant agent can improve the UV resistance of the silicone product 1, and the weather-resistant agent can improve the weather resistance of the silicone product 1.

[0065] In some embodiments, the hydrophobic agent may be an organosilicon resin, such as polydimethylsiloxane (PPMS); the hydrophobic agent may also be a fluorinated silane, such as trifluoropropyltrichlorosilane.

[0066] In some embodiments, the anti-scratch agent may be silica nanoparticles or a polyurethane (PU) modifier.

[0067] In some embodiments, the UV stabilizer can be a UV absorber (UVA), such as a benzotriazole compound; the UV stabilizer can also be a light stabilizer (HALS), such as a hindered amine light stabilizer.

[0068] In some embodiments, the weathering agent may be an antioxidant, such as a hindered phenolic antioxidant; the weathering agent may be a light stabilizer, such as HALS or other benzotriazoles.

[0069] All silicon components in this invention can be organosilicon. In this case, organosilicon has advantages over ordinary silicon, such as antifouling, resistance to high and low temperatures, weather resistance, hydrophobicity, and antibacterial properties. When the surface layer is made of organosilicon, the organosilicon product 1 can have good antifouling, high and low temperature resistance, weather resistance, hydrophobicity, and antibacterial properties.

[0070] According to the present invention, an organosilicon product 1 that is easy to print patterns on and easy to clean and maintain can be provided.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
