Description

Technical Field

[0001] This utility model belongs to the field of glass wool technology, specifically relating to a highly flame-retardant glass wool product. Background Technology

[0002] In the construction and industrial sectors, glass wool products are widely used as a common thermal insulation material due to their excellent thermal insulation performance and cost-effectiveness.

[0003] Traditional glass wool products typically consist of a glass wool substrate and a layer of aluminum foil bonded to the surface of the substrate. This structure can meet basic thermal insulation requirements to a certain extent. However, with increasingly stringent requirements for the safety and environmental performance of building materials, traditional glass wool products have shown shortcomings in fire safety, durability, and environmental adaptability.

[0004] Traditional glass wool products only have a layer of aluminum foil bonded to the surface. This single protective measure is insufficient to provide effective fire protection. In the event of a fire, the aluminum foil may melt rapidly, causing the glass wool substrate to be directly exposed to high temperatures, thus losing its insulation function and increasing the risk of fire spread. Existing glass wool products are also susceptible to environmental influences; for example, moisture penetration can cause the substrate to become damp, reducing its insulation performance and service life.

[0005] In view of this, we propose a highly flame-retardant glass wool product to solve the above problems. Utility Model Content

[0006] The present invention aims to solve the technical problem that glass wool products in the prior art have significant shortcomings in fire resistance, durability, environmental adaptability and environmental protection performance compared with highly flame-retardant glass wool products.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A highly flame-retardant glass wool product includes a glass wool substrate, a waterproof layer, a flame-retardant layer, a heat insulation layer, and a protective layer. The inner and outer sides of the glass wool substrate are coated with a surface coating to improve its flame-retardant and fire-resistant properties. The waterproof layer prevents moisture penetration into the glass wool substrate and is bonded to the inner side of the substrate. The flame-retardant layer, in conjunction with the surface coating, provides double-layer fire resistance and flame retardancy to the outer layer of the glass wool substrate. The flame-retardant layer is located outside the surface coating and away from the waterproof layer. The heat insulation layer, in conjunction with the surface coating and the flame-retardant layer, forms a composite structural layer on the surface of the glass wool substrate and is bonded to the surface of the flame-retardant layer. The protective layer is bonded to the outer side of the heat insulation layer and serves for waterproofing and fireproofing.

[0009] Preferably, the surface coating is located between the waterproof layer and the glass wool substrate, and the surface coating includes a high-temperature ceramic coating and an inorganic fireproof coating, with the high-temperature ceramic coating located on the surface of the glass wool substrate.

[0010] High-temperature ceramic coatings provide an additional layer of protection for glass wool substrates, preventing direct exposure to high temperatures and thus maintaining their structural integrity and flame-retardant properties. Inorganic fire-retardant coatings, located beneath the high-temperature ceramic coating, provide further fire protection on top of it. Inorganic fire-retardant coatings typically possess good thermal stability and non-flammability, forming a char layer at high temperatures to prevent flame propagation.

[0011] Preferably, the waterproof layer is bonded to the surface of the inorganic fire-retardant coating using polyurethane or epoxy resin adhesive. The waterproof layer is a polyethylene film layer or a polyester film layer. Polyurethane or epoxy resin adhesives have high bonding strength, ensuring a strong bond between the waterproof layer and the inorganic fire-retardant coating. Both polyethylene and polyester films are excellent waterproof materials, effectively preventing moisture penetration.

[0012] Preferably, the flame-retardant layer is made of alkali-free or low-alkali glass fiber mixed with a flame retardant, and is bonded to the surface of the inorganic fire-retardant coating by a fiber material adhesive or by hot-melt bonding technology. Alkali-free or low-alkali glass fiber itself has good flame retardancy.

[0013] Preferably, the insulation layer is an asbestos board or aluminum silicate fiber felt, which is bonded to the surface of the flame-retardant layer. Both asbestos board and aluminum silicate fiber felt are highly efficient insulation materials that can effectively reduce heat transfer.

[0014] Preferably, the protective layer is an aluminum foil or stainless steel sheet bonded to the surface of the insulation layer. The aluminum foil or stainless steel sheet provides additional mechanical protection and enhances the overall structural strength.

[0015] Preferably, an adhesive layer is also provided on the inner surface of the waterproof layer, and a release liner is provided on the outside of the adhesive layer. The release liner can be easily removed during construction, making the installation process simpler.

[0016] Preferably, the inner surface of the glass wool substrate has evenly distributed protrusions. The protrusions can increase the bonding strength and mechanical strength of the highly flame-retardant glass wool product during bonding.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] This highly flame-retardant glass wool product achieves double or even multi-layered fireproof and flame-retardant protection by spraying high-temperature ceramic coatings and inorganic fire-retardant coatings onto both the inner and outer sides of the substrate. The high-temperature ceramic coating, located on the surface, can withstand high-temperature environments, protecting the substrate from direct heat damage, while the inorganic fire-retardant coating further provides fire protection, forming a charred layer to inhibit flame propagation. The working principle of this structure is that the synergistic effect of different coatings significantly improves the overall flame-retardant performance and fire safety, thus providing more effective protection for buildings in the event of a fire.

[0019] The waterproof, heat-insulating, and protective layers in this product provide comprehensive protection against moisture penetration, heat conduction, and mechanical strength issues. The waterproof layer uses polyurethane or epoxy resin adhesive to bond a polyethylene or polyester film, effectively preventing moisture from penetrating the substrate and keeping it dry. The heat-insulating and protective layers utilize asbestos board, aluminum silicate fiber felt, and aluminum foil or stainless steel plate, respectively, reducing heat transfer while enhancing the overall structural strength and durability. These layers work in a progressive manner, collectively constructing a stable protective system that ensures the product's performance stability and structural integrity during long-term use.

[0020] To improve bonding strength and ease of construction, the inner surface of the waterproof layer of the product is equipped with an adhesive layer and protected with release paper. Furthermore, the inner surface of the glass wool substrate is uniformly covered with raised sections, increasing the bonding area and mechanical strength. These designs work by optimizing the bonding interface and reinforcing the substrate structure, improving the overall stability and durability of the product, making installation simpler and faster, and reducing the frequency of maintenance and replacement, thus achieving a dual improvement in long-term economic and environmental benefits.

[0021] High flame-retardant glass wool products form a multi-layered protective system through the application of a surface coating, a waterproof layer, a flame-retardant layer, a heat insulation layer, and a protective layer. Traditional products lack this composite structure and cannot provide the same level of protection. Attached Figure Description

[0027] The technical solutions of the present 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 the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figure 1 As shown, a high flame-retardant glass wool product includes a glass wool substrate 1, a waterproof layer 3, a flame-retardant layer 4, a heat insulation layer 5, and a protective layer 6. The glass wool substrate 1 has a flat surface structure, and the inner and outer sides of the glass wool substrate 1 are coated with a surface coating 2 that is applied to the surface of the glass wool substrate 1 to improve the flame-retardant effect and fire resistance of the glass wool substrate 1.

[0030] The surface coating 2 is located between the waterproof layer 3 and the glass wool substrate 1. The surface coating 2 includes a high-temperature ceramic coating 21 and an inorganic fireproof coating 22. The high-temperature ceramic coating 21 is located on the surface of the glass wool substrate 1.

[0031] The high-temperature ceramic coating 21 typically possesses high temperature resistance and strong mechanical strength, therefore it is usually sprayed onto the surface of the glass wool substrate 1, which is directly exposed to potentially high-temperature environments. The high-temperature ceramic coating 21 provides an additional layer of protection for the glass wool substrate 1, preventing high temperatures from directly affecting the glass wool substrate 1, thereby maintaining its structural integrity and flame-retardant properties;

[0032] The inorganic fire-retardant coating 22 is located below the high-temperature ceramic coating 21, and its function is to provide further fire protection on top of the high-temperature ceramic coating 21. The inorganic fire-retardant coating 22 typically has good thermal stability and non-flammability, and can form a char layer at high temperatures, thereby preventing the spread of flames;

[0033] The high-temperature ceramic coating 21 is located on the surface of the glass wool substrate 1. This configuration ensures that when the glass wool substrate 1 is exposed to a high-temperature fire source, it can be protected by the dual protection of the high-temperature ceramic coating 21 and the inorganic fireproof coating 22, effectively improving the overall flame retardant performance and fire safety. At the same time, this structure also helps to improve the durability and service life of glass wool products.

[0034] The waterproof layer 3 is used to prevent moisture from penetrating into the glass wool substrate 1. The waterproof layer 3 is bonded to the inside of the glass wool substrate 1. The waterproof layer 3 is bonded to the surface of the inorganic fire-retardant coating 22 using polyurethane or epoxy resin adhesive. The waterproof layer 3 is a polyethylene film layer or a polyester film layer. Polyurethane or epoxy resin adhesives have high bonding strength, ensuring a strong bond between the waterproof layer 3 and the inorganic fire-retardant coating 22. These adhesives typically have good chemical resistance, resisting corrosive substances in the environment. Polyethylene and polyester films are both good waterproof materials, effectively preventing moisture penetration. These materials are generally abrasion-resistant, maintaining their waterproof function for a long time.

[0035] The flame-retardant layer 4 works in conjunction with the surface coating 2 to provide double-layer fireproofing and flame retardancy for the outer layer of the glass wool substrate 1. The flame-retardant layer 4 is located on the outside of the surface coating 2 and faces away from the waterproof layer 3. The flame-retardant layer 4 is made of alkali-free or low-alkali glass fiber mixed with a flame retardant. The flame-retardant layer 4 is bonded to the surface of the inorganic fireproof coating 22 using a fiber adhesive or hot-melt bonding technology. Alkali-free or low-alkali glass fiber itself has good flame retardancy, and when mixed with a flame retardant, it provides an even higher flame-retardant effect. Alkali-free or low-alkali glass fiber can reduce the corrosive effects on the environment and materials.

[0036] The heat insulation layer 5, together with the surface coating 2 and the flame-retardant layer 4, forms a composite structural layer on the surface of the glass wool substrate 1. The heat insulation layer 5 is bonded to the surface of the flame-retardant layer 4. The heat insulation layer 5 is either asbestos board or aluminum silicate fiber felt, and is bonded to the surface of the flame-retardant layer 4. Both asbestos board and aluminum silicate fiber felt are highly efficient heat insulation materials that can effectively reduce heat transfer. These materials can maintain their stability at high temperatures and are not easily deformed.

[0037] The protective layer 6 is bonded to the outer surface of the insulation layer 5 and serves for waterproofing and fireproofing. The protective layer 6 is an aluminum foil or stainless steel sheet bonded to the surface of the insulation layer 5. The aluminum foil or stainless steel sheet provides additional mechanical protection and enhances the overall structural strength. Aluminum foil has excellent heat reflectivity, which further improves the insulation effect.

[0038] By spraying a surface coating 2 onto both the inner and outer sides of the glass wool substrate 1 and adding a flame-retardant layer 4, this product can provide double or even multiple layers of fireproof and flame-retardant protection, greatly improving its fire safety performance. The presence of a waterproof layer 3 prevents moisture from penetrating into the glass wool substrate 1, protecting the substrate from dampness and extending its service life. The thermal insulation layer 5 effectively blocks heat conduction, playing a crucial role in maintaining stable indoor temperatures and saving energy and reducing emissions. The addition of a protective layer 6 not only provides extra waterproof and fireproof protection but also enhances the overall durability and resistance to external environmental erosion. This composite glass wool product can adapt to various environments, maintaining its performance even in humid or high-temperature conditions. Due to its excellent physical and chemical properties, its installation in building and industrial applications is more convenient and faster. Although the initial investment may be higher than ordinary glass wool products, its superior durability and long-term performance reduce the frequency of maintenance and replacement, thus achieving long-term economic benefits. Highly flame-retardant glass wool products, while improving safety, also align with current green and environmentally friendly building concepts, contributing to the sustainable development of the construction industry.

[0039] In summary, this highly flame-retardant glass wool product has significant advantages in improving safety performance, extending service life, enhancing durability, and being environmentally friendly.

[0040] Example 2

[0041] like Figure 2-4 As shown, based on Example 1, the difference is that the surface of the glass wool substrate 1 is not a flat structure. Instead, the inner surface of the glass wool substrate 1 has evenly distributed protrusions 11, while the outer surface is a flat structure. An adhesive layer 7 is also provided on the inner surface of the waterproof layer 3, and release paper 8 is provided on the outside of the adhesive layer 7. The adhesive layer 7 facilitates the bonding and fixing of the high flame-retardant glass wool product during construction. The release paper 8 can be easily removed during construction, making the installation process simpler. The release paper 8 can protect the adhesive layer 7 from contamination or damage before construction. The protrusions 11 can increase the bonding strength and mechanical strength of the high flame-retardant glass wool product during bonding, making the overall structure more stable.

[0042] The high flame-retardant glass wool product in Example 1 achieves excellent fireproof, waterproof, heat insulation, and protective effects through a multi-layered structural design that utilizes the properties of different materials. The high-temperature ceramic coating 21 and inorganic fire-retardant coating 22 sprayed onto the surface of the glass wool substrate 1 provide dual fire protection. The high-temperature ceramic coating 21 directly faces the high-temperature environment, while the inorganic fire-retardant coating 22 further prevents flame propagation from below. The waterproof layer 3, flame-retardant layer 4, heat insulation layer 5, and protective layer 6 each play their respective roles, collectively improving the overall flame-retardant performance and service life.

[0043] Example 2 is an optimization of Example 1. The protrusions 11 on the inner surface of the glass wool substrate 1 increase the contact area with the adhesive layer 7, thereby improving the bonding strength and mechanical strength. At the same time, the design of the adhesive layer 7 and release paper 8 on the inner surface of the waterproof layer 3 ensures convenience during construction and protection of the adhesive layer 7.

[0044] This design enhances the fire safety of glass wool products, effectively preventing the spread of fire through multi-layered protection and ensuring the safety of people and property. Simultaneously, the waterproof layer 3 protects the glass wool substrate 1 from moisture, extending the product's lifespan. Furthermore, the thermal insulation layer 5 contributes to energy conservation and emission reduction, maintaining stable indoor temperatures and aligning with green building principles.

[0045] In terms of construction and installation, the design of the adhesive layer 7 and release paper 8 makes the installation process simpler, improves construction efficiency, and reduces installation costs. Meanwhile, the raised portion 11 on the inner surface of the glass wool substrate 1 enhances the stability of the overall structure, enabling the product to maintain good performance in various environments and making it less susceptible to external environmental influences.

[0046] Through meticulous material selection and structural design, this highly flame-retardant glass wool product not only improves safety and durability but also enhances installation convenience and environmental friendliness, providing the construction industry with a safer, more efficient, and economical solution that aligns with the development trends and needs of the contemporary construction industry.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
