Description

Technical Field

[0001] This utility model relates to the field of mineral wool board processing technology, specifically to a reinforced coating structure for preventing edge and corner peeling of mineral wool boards. Background Technology

[0002] Mineral wool board, a building decoration material made primarily from mineral fibers, is widely used in interior ceilings and wall decorations due to its excellent sound absorption, heat insulation, and fire resistance properties. However, in practical applications, it has been found that traditional mineral wool boards, due to their inherent material characteristics and production process limitations, have inherent defects such as low structural density and weak fiber bonding in the edges and corners. This makes the edges and corners susceptible to micro-cracks, chipping, or even partial detachment during transportation, installation, and use, caused by external impacts, humidity changes, or mold growth. This not only affects the overall aesthetics and service life of the decorative surface but may also pose safety hazards due to falling debris. Therefore, a reinforced coating structure for preventing the detachment of mineral wool board edges and corners is proposed. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a reinforced coating structure for preventing the edge and corner of a mineral wool board from falling off.

[0004] The technical solution adopted by this utility model to solve its technical problem is a mineral wool board edge corner anti-detachment reinforced coating structure, including a mineral wool board edge corner base layer, a moisture-proof reinforcement layer sprayed on one side of the mineral wool board edge corner base layer, a flexible reinforcement layer sprayed on the side of the moisture-proof reinforcement layer away from the mineral wool board edge corner base layer, an anti-mildew and antibacterial coating sprayed on the side of the flexible reinforcement layer away from the moisture-proof reinforcement layer, and a durable protective layer sprayed on the side of the anti-mildew and antibacterial coating away from the flexible reinforcement layer.

[0005] By adopting the above technical solution and through a multi-layer composite coating structure design, combining the synergistic effects of a moisture-proof reinforcement layer, a flexible reinforcement layer, an anti-mildew and antibacterial layer, and a durable protective layer, the moisture-proof and impermeable capabilities and structural toughness of the mineral wool board edges and corners are significantly improved. This effectively absorbs stress deformation caused by changes in temperature and humidity. Furthermore, through long-lasting antibacterial and weather-resistant protection functions, it comprehensively inhibits biological corrosion and environmental erosion, thereby completely solving the problem of easy cracking and detachment of traditional mineral wool board edges and corners, greatly extending its service life and ensuring the safety and aesthetics of decorative projects.

[0006] Specifically, the moisture-proof reinforcement layer includes a silane-modified epoxy primer layer.

[0007] By employing the above technical solution, the silane-modified epoxy primer layer, when applied to the surface of the mineral wool board edge substrate, can penetrate into the pores of the mineral wool board edge substrate, forming a dense moisture barrier that effectively prevents moisture erosion and avoids substrate deformation or mold growth due to moisture. Its low surface tension characteristics enhance the adhesion of subsequent coatings.

[0008] Specifically, the flexible reinforcing layer includes a vulcanized silicone rubber layer.

[0009] By adopting the above technical solution, the vulcanized silicone rubber layer has high elasticity and temperature resistance of -50℃ to 200℃. It can absorb the stress deformation of the mineral wool board caused by temperature and humidity changes, prevent the coating from cracking or peeling, and at the same time make up for minor defects in the base layer and improve the overall impact resistance.

[0010] Specifically, the anti-mildew and antibacterial coating comprises a mixture of epoxy resin and silver ion antibacterial agent.

[0011] By adopting the above technical solutions, silver ions can effectively inhibit the growth of mold and bacteria by destroying the cell membrane and DNA structure of microorganisms, thus avoiding odors and biological corrosion; epoxy resin provides a dense physical barrier to block the conditions for microbial attachment.

[0012] Specifically, the durable protective layer includes a fluorocarbon topcoat layer.

[0013] By adopting the above technical solution, the fluorocarbon topcoat layer has excellent resistance to ultraviolet rays, acids and alkalis and anti-fouling properties due to the high bond energy characteristics of the CF bond.

[0014] The beneficial effects of this utility model are:

[0015] The mineral wool board edge and corner anti-detachment reinforced coating structure described in this utility model, through a multi-layer composite coating structure design, combines the synergistic effects of a moisture-proof reinforcement layer, a flexible reinforcement layer, an anti-mildew and antibacterial layer, and a durable protective layer. This not only significantly improves the moisture-proof and seepage-proof capabilities and structural toughness of the mineral wool board edges and corners, effectively absorbing stress deformation caused by temperature and humidity changes, but also comprehensively inhibits biological corrosion and environmental erosion through long-lasting antibacterial and weather-resistant protection functions. Thus, it completely solves the problem of easy cracking and detachment of traditional mineral wool board edges and corners, greatly extends the service life, and ensures the safety and aesthetics of decorative projects.
