[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figure 1 This invention provides a flame-retardant silicone product that can be attached to a target object. In some embodiments, the flame-retardant silicone product may include an aramid material layer 2 with flame-retardant properties and a silicone layer 1 coated on the side of the aramid material layer 2 away from the target object. The side of the aramid material layer 2 away from the silicone layer 1 can be attached to the target object. This attachment can be direct mounting or pasting with an external object. The flame-retardant silicone product of this invention can be applied to wall stickers, sofas, seats, high-speed rail interiors, aircraft interiors, and other fields. In addition, utilizing the bulletproof properties of aramid material, it can also be used in the manufacture of bulletproof vests and other bulletproof products.

[0024] In some embodiments, the flame-retardant silicone product may further include an adhesive layer 3, which may be coated on the side of the aramid layer 2 away from the silicone layer 1. The flame-retardant silicone product can be used for adhesion to a target object, and may include a silicone layer 1, an aramid layer 2, and an adhesive layer 3 stacked sequentially. In this invention, the aramid layer 2 has good flame-retardant properties, and as the bottom layer, it can improve the flame-retardant properties of the flame-retardant silicone product. The silicone layer 1, as the top layer, can improve the hydrophobicity, wear resistance, stain resistance, scratch resistance, and environmental friendliness of the surface of the flame-retardant silicone product. At the same time, the surface of the silicone layer has rich textures and colors, and a good tactile feel.

[0025] In some embodiments, the aramid material layer 2 can be aramid paper or aramid fabric. Aramid paper is easy to adhere to the target object after gluing and can improve the adhesion to the target object. Aramid fabric can be directly attached to the target object, such as as leather for sofas or chairs.

[0026] The aramid paper or aramid cloth of this invention can be a material whose main component is aramid fiber. Aramid cloth can also be called Kevlar cloth. The materials of aramid cloth are mainly divided into two categories: aramid 1414 (poly(p-phenylene terephthalamide)) and aramid 1313 (poly(m-phenylene isophthalamide)). The main components of aramid paper are chopped aramid fibers and precipitated aramid fibers.

[0027] In some embodiments, the silicone layer 1 can be one to three layers. The number of silicone layers 1 is also not limited to one to three layers. Increasing the number of silicone layers 1 can improve wear resistance, while decreasing the number of silicone layers 1 can increase the transparency of the silicone layer.

[0028] In some embodiments, the silicone layer 1 may be transparent.

[0029] In some embodiments, the aramid material layer 2 may have a specific pattern. This allows the specific pattern on the aramid material layer 2 to be easily displayed through the transparent silicone layer 1.

[0030] In some embodiments, the thickness of the aramid material layer 2 can be from 25 micrometers to 250 micrometers.

[0031] In some embodiments, the surface of the silicone layer 1 may have a specific texture. When the silicone layer is multilayered, the surface layer of the silicone layer may have a specific texture. This enriches the texture of the surface of the silicone layer 1 and improves its aesthetics.

[0032] In some embodiments, a tactile layer may be coated on the silicone layer 1 away from the aramid material layer. The tactile layer may be a tactile oil. This improves the tactile feel of the silicone layer 1.

[0033] In some embodiments, the adhesive layer 3 may comprise a phosphorus-containing flame retardant and an adhesive. Thus, by adding a phosphorus-containing flame retardant to the adhesive layer 3, the flame retardant properties of the flame-retardant silicone product can be improved without affecting the adhesive properties of the adhesive layer 3.

[0034] In some embodiments, the adhesive may be polyurethane, acrylic, or acrylic self-adhesive.

[0035] In some embodiments, the adhesive layer 3 may be PU and / or PUR hot melt adhesive.

[0036] In some embodiments, the target object is a flammable material such as a wooden board, a chair, or a sofa.

[0037] In some embodiments, a certain amount of aluminum hydroxide can be added to the organosilicon layer 1. Aluminum hydroxide undergoes a decomposition reaction upon heating; this decomposition reaction is endothermic and absorbs a large amount of heat, thereby reducing the temperature of the combustion zone. Additionally, 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 also carry away some heat, further reducing 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 organosilicon material, thereby inhibiting the combustion reaction. Therefore, the flame-retardant properties of the flame-retardant organosilicon product can be further improved.

[0038] In some embodiments, a certain amount of magnesium hydroxide may be added to the silicone layer 1. Similar to the effect of adding aluminum hydroxide, adding magnesium hydroxide can also improve the flame retardant properties of flame-retardant silicone products.

[0039] In some embodiments, a certain amount of magnesium hydroxide and expanded graphene may be added to the organosilicon layer 1. The two can have a synergistic flame-retardant effect.

[0040] In some embodiments, the silicone layer 1 may be made of liquid silicone (non-internalized silicone). For example, one or more layers of liquid silicone may be sequentially coated onto the release layer to form the silicone layer 1.

[0041] In some embodiments, the silicone layer 1 may include three silicone layers, such as a first silicone layer, a second silicone layer, and a third silicone layer. The first silicone layer, the second silicone layer, and the third silicone layer can be formed by sequentially coating liquid silicone onto the silicone layer.

[0042] In some embodiments, the thickness of the first silicone layer may be 0.02 mm to 0.2 mm; the thickness of the second silicone layer may be 0.02 mm to 0.2 mm; and the thickness of the third silicone layer may be 0.05 mm to 0.4 mm.

[0043] In some embodiments, the side of the silicone layer 1 adjacent to the aramid layer 2 can be treated for easy adhesion. This enhances the bonding strength between the silicone layer 1 and the aramid layer 2.

[0044] In some embodiments, the easy-bonding treatment can be plasma treatment, corona treatment, primer treatment (containing silicone), etc.

[0045] In some embodiments, when the aramid material layer 2 is aramid fabric, the surface of the aramid fabric away from the silicone layer 1 can be directly attached to the target object without relying on the adhesive properties of the adhesive layer 3. For example, when the target object is a chair or sofa, the surface of the aramid fabric away from the silicone layer 1 can be directly attached to the surface of the chair or sofa for use.

[0046] In some embodiments, when the aramid material layer 2 is aramid paper, patterns or logos can be printed on the aramid paper, and the silicone layer 1 can be transparent. Thus, the patterns on the aramid paper can be clearly displayed through the transparent silicone layer 1.

[0047] Of course, when the aramid material layer 2 is aramid fabric, specific patterns can also be sewn or printed on the aramid fabric. In this case, the silicone layer 1 can be transparent. Thus, the patterns on the aramid fabric can be clearly displayed through the transparent silicone layer 1.

[0048] In some embodiments, the thickness of the aramid fabric can be from 0.2 to 1.4 mm.

[0049] In some embodiments, the thickness of the aramid paper can be from 0.02 to 0.8 mm.

[0050] In some embodiments, the aramid layer can be Nomex paper. Nomex possesses insulating, shielding, and anti-interference properties, high electrical insulation, mechanical strength, softness, and elasticity. It is particularly resistant to acid and alkali corrosion, tear and abrasion resistant, insensitive to moisture, non-toxic, flame retardant, and has strong inherent dielectric strength, mechanical toughness, flexibility, resilience, and good thermal stability. Using an adhesive layer, flame-retardant silicone products can be easily and firmly adhered to the target object. Furthermore, utilizing Nomex's excellent flame-retardant properties, when flame-retardant silicone products are used as wallpaper, the flame-retardant performance of the silicone products can be significantly improved.

[0051] In some embodiments, the aramid material layer 2 can be replaced with DuPont paper (such as Tyvek), cardboard, kraft paper, coated paper, or specialty paper (such as art paper, pearlescent paper, etc.). In this case, utilizing the lightweight, abrasion-resistant, flexible, waterproof, breathable, antibacterial, dustproof, corrosion-resistant, printable, and environmentally friendly properties of Tyvek, on the one hand, it is easy to apply adhesives onto it, and the adhesive layer can easily and firmly adhere the flame-retardant silicone product to the target object; on the other hand, utilizing the aforementioned properties of DuPont paper, the waterproof, breathable, and abrasion-resistant properties of the flame-retardant silicone product can be improved.

[0052] In some embodiments, the flame-retardant silicone article may further include a release layer, which may be disposed on the side of the silicone layer 1 away from the aramid material layer 2. This facilitates the coating of the silicone layer onto the silicone layer.

[0053] In some embodiments, the release layer may be release paper or release film.

[0054] In some embodiments, the adhesive layer 3 can be a pressure-sensitive adhesive, a UV-curable adhesive, an OCA adhesive coating, an acrylic adhesive coating, or a silicone coating. Alternatively, the adhesive layer 3 can be formed by performing an adhesive treatment on the aramid material layer 2.

[0055] In some embodiments, a tactile layer may be provided on the side of the silicone layer 1 away from the aramid material layer 2. The tactile layer may be a tactile oil.

[0056] In some embodiments, the silicone layer 1 may include at least one of a silicone resin and a fluorosilicone polymer. This improves the mechanical properties and antifouling and hydrophobic properties of the flame-retardant silicone article.

[0057] In some embodiments, the silicone resin may include at least one of VMQ silicone resin, MQ silicone resin, and fluorosilicone resin.

[0058] Tests have shown that the flame retardant rating of the flame-retardant silicone products of this invention can reach V1 (UL 94 standard) or above or B1 (GB 8624) or above.

[0059] According to this invention, a flame-retardant silicone product that is easy to adhere to a target object can be provided.

[0060] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 this utility model.
