Description

Technical Field

[0001] The present invention relates to the technical field of building materials, and more particularly to a titanium-ceramic silicate board. Background Art

[0002] Silicate fiberboard is suitable for decorative applications in walls, suspended ceilings, ceilings, floors, ship compartments, air ducts, industrial plants, public buildings, and residential structures. It is typically installed by securing it with a keel. It has gained widespread attention and favor in the construction industry. However, in practical applications, some traditional silicate fiberboards suffer from poor surface decorative properties, susceptibility to contamination, and insufficient weather resistance. Furthermore, conventional fire-retardant coatings struggle to maintain A1-class fire resistance while simultaneously enhancing surface hardness and corrosion resistance.

[0003] Referring to a silicate fireproof board with reference to patent publication number CN218149023U, the sliding force of the slide rod inside the sleeve makes it easy for the limit block to retract inward when it is squeezed by the card plate, and through the elastic reset force of the spring, the limit block is easy to automatically pop out and engage with the limit slot after corresponding to the limit slot, which is convenient for positioning the position of the fireproof partition and subsequent bonding between the fireproof partition and the first fireproof substrate and the second fireproof substrate to prevent skew. However, the surface treatment of the silicate fireproof board mentioned in the patent uses ordinary paint, which has the problem of insufficient high temperature resistance.

[0004] Therefore, it is difficult to balance the combustion performance and surface treatment and decorative performance of existing panels, which limits their application in high-end buildings.

[0005] Therefore, in view of this, the existing structure is studied and improved, and a titanium ceramic silicate plate is provided in order to achieve a purpose with greater practical value. Summary of the Invention

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Example 1:

[0039] See also Figure 1 The titanium-ceramic silicate board and silicate fiberboard are composed of a silicate fiber substrate layer 1, a titanium-ceramic primer layer 2, and a titanium-ceramic topcoat layer 3. The titanium-ceramic primer layer 2 is sprayed onto all exterior surfaces of the silicate fiber substrate layer 1, forming an inner coating layer. The titanium-ceramic topcoat layer 3 is sprayed onto all exterior surfaces of the titanium-ceramic primer layer 2, forming an outer coating layer. This allows the coating structure to completely encase the silicate fiber substrate layer 1, providing all-round fire protection for the silicate fiberboard.

[0040] The silicate fiber base material layer 1 is a silicate fiber board with a thickness of 6 mm to 12 mm.

[0041] Specifically, the density of the silicate fiber board of the silicate fiber substrate layer 1 is 180 to 220 kg / m 3 , its thermal conductivity is ≤0.045W / (m·K), and its topcoat layer combustion performance grade is A1. A1 is the grade of non-combustible materials, and A1 grade materials will not produce open flames or fire on the surface during a fire, and will produce less smoke during a fire. In summary, silicate fiberboard has moderate density, is not easy to conduct heat and is not easy to burn, and has excellent fire resistance.

[0042] The titanium ceramic primer layer 2 is a coating structure of a titanium ceramic primer.

[0043] Specifically, the titanium ceramic primer layer 2 includes the following components in weight percentage:

[0044]

[0045] The sum of the weight percentages of nano-titanium dioxide, ceramic microbeads, and flame-retardant silicone resin is not greater than 100%. In this way, other materials can be compounded to improve the performance of the titanium ceramic primer layer 2.

[0046] The titanium enamel topcoat is composed of the above-mentioned silicon material and titanium oxide, aluminum oxide and rare earth.

[0047] The synergistic effect of nano-titanium dioxide and ceramic microbeads in the titanium enamel paint formula improves UV reflectivity and impact resistance. Among them, the UV reflectivity is ≥95% and the impact resistance is ≥5J.

[0048] The titanium ceramic topcoat layer 3 is a coating structure added with water-based inorganic nano titanium ceramic paint, and its thickness is 25 to 40 μm.

[0049] Through the flame retardant synergy of the silicate fiber substrate layer 1, the titanium porcelain primer layer 2, and the titanium porcelain topcoat layer 3, the combustion performance of the final silicate fiberboard reaches GB 8624-2012A1 level, and the smoke density level is ≤5.

[0050] Example 2:

[0051] Based on the above embodiment 1, further description is given.

[0052] See also Figure 2 The silicate fiberboard is based on the silicate fiber substrate layer 1. The specific implementation steps of the silicate fiberboard preparation method are as follows:

[0053] Step 1. Raw material preparation: Select high-quality silicate fiber as the base material to ensure the light weight and high strength characteristics of the material.

[0054] Specifically, the chemical composition of the silicate fiber includes one or more of SiO2, Al2O3, CaO, and MgO, and the fiber diameter is 3 to 5 μm and the length is 10 to 15 mm.

[0055] Step 2: Sheet forming: The silicate fibers are formed into a sheet with a thickness of 6 mm to 12 mm through a wet forming process. The wet forming process is a known process method and will not be described in detail here.

[0056] Specifically, silicate fibers were mixed with water and a binder, and formed into a 12 mm thick plate through a wet forming process, and then dried at 120° C. for 2 h.

[0057] Step 3: Surface treatment: The surface of the plate is treated by a titanium enamel spraying process. The coating is formed into a gradient structure through a staged curing process, and finally a preliminary finished plate is formed to improve the weather resistance and aesthetics of the plate. Among them, the titanium enamel spraying process is a known process method and will not be described in detail here.

[0058] Specifically, the titanium porcelain primer layer 2 and the titanium porcelain topcoat layer 3 are sprayed using a titanium porcelain paint spraying process, wherein the spraying thickness of the titanium porcelain primer layer 2 is 1 to 3 μm, and the spraying thickness of the titanium porcelain topcoat layer 3 is 25 to 40 μm.

[0059] After spraying, the coating is cured at a temperature of 180°C for 30 minutes to form a dense ceramic surface.

[0060] Step 4: Combustion performance test: Conduct a combustion performance test on the preliminary finished panels to ensure that they meet the A1 standard. Panels that meet the A1 standard are determined as the final finished panels.

[0061] Specifically, when conducting the combustion performance test, the test standard is GB / T5464-2010 standard.

[0062] Combustion grade test name A Non-combustible material products <![CDATA[B1]]> Flame-retardant material products <![CDATA[B2]]> Combustible material products <![CDATA[B3]]> Products made of flammable materials

[0063] Combustion grade A1 is a type of combustion grade A, which reflects the excellent fire resistance of silicate fiberboard.

[0064] Step 5. Quality Inspection: Conduct a comprehensive quality inspection on the final finished plate to ensure that the product meets the design requirements.

[0065] By optimizing the composition and process of the silicate substrate and titanium-ceramic coating, A1-level fire protection, high weather resistance and decorative properties are integrated. By optimizing the raw material selection, molding process and surface treatment process, the comprehensive performance of the silicate fiberboard is significantly improved, achieving A1-level fire protection, high surface hardness and weather resistance of the silicate fiberboard, meeting the high-performance requirements of scenes such as building exterior walls and interior partitions, and is widely used in construction, shipbuilding, aerospace and other fields, with broad market application prospects.

[0066] Specifically, the quality inspection contents include appearance, size, strength and combustion performance.

[0067] When judging the strength, the pencil hardness of the final product board is determined. When the pencil hardness is ≥5H, the strength is qualified, which reflects the excellent hardness performance of the silicate fiberboard.
