    Structural glue refers to high strength (compression strength>65MPa, steel-steel positive pull bonding strength>30MPa, shear strength >18MPa), can withstand large loads, and resistance to aging, fatigue, corrosion resistance, stable performance in life expectancy, suitable for strong structural parts bonding adhesive.
    the use of structural glue
    high strength, anti-stripping, impact-resistant, simple construction process. For bonding between metals, ceramics, plastics, rubber, wood and other materials or between different

    . Can partially replace welding, riveting, bolting and other traditional forms of connection. The binding surface stress is evenly distributed, which has no thermal effect and deformation on the part.
    In the project, structural glue is widely used, mainly used in the reinforcement of components, anchoring, bonding, repair, etc. , such as viscose steel, sticky carbon fiber, planting ribs, crack reinforcement, sealing, hole repair, nail paste, surface protection, concrete bonding and so on.
    The performance advantages of structural glue
    1, uniform distribution of stress, high freedom of material selection
    First, the use of structural glue stress can be evenly dispersed throughout the bonding surface, eliminating the traditional spot welding, riveting, bolt fixation and other ways caused by stress concentration problems. As a result, lighter and thinner materials can be used without losing component strength. Secondly, it can effectively bond heterogeneous materials and improve the comprehensive performance. Different materials can then be made of laminate by using structural adhesive bonding, which combines the strength and comprehensive properties of each material. At the same time, the toughness of structural glue can effectively solve the problem of inconsistent coefficients of thermal expansion between different materials in the application, such as the bonding application of aluminum and glass. Structural glues can also be used as an isolation layer to reduce or even eliminate electrochemical corrosion between different metals.
    2, reduce surface defects and save trim costs
    components assembled with structural glue maintain component integrity and eliminate surface defects caused by mechanical connection points and welding. The use of structural bonding can greatly improve process design flexibility and reduce dressing work. Structural adhesives also provide optimal fatigue performance, and the excellent toughness of the adhesive allows the components to be repeatedly stretched and restored under repeated force conditions. The energy absorption of the adhesive ensures fatigue resistance of up to 20 times that of welded or riveted parts. The overall continuous connection of the assembly components formed by bonding ensures effective bonding and sealing in the working environment.
    3, reduce costs, environmentally
    and choose structural adhesive can reduce costs while simplifying the production process. Bonding processes reduce substrate requirements, reduce weight, eliminate drilling, welding, screw fixing, and similar processes, ultimately reducing costs while increasing productivity. It can be operated with only a small amount of training and does not produce harmful solvent emissions when using structural adhesive bonding for bottom coating or coated material. Structural glues demonstrate superior cost, productivity, light weight, and performance over traditional connections. In most production applications, structural glues provide higher strength and longer life for components.
    main types of structural glue
    1, high-performance silicone structure glue
    high-performance silicone structure glue is a single component, neutral curing, designed for structural bonding assembly in the building curtain wall. It can be easily extruded and used at very wide temperatures, and the water in the air is solidified into excellent, durable, high-mod, highly elastic silicone rubber.
    2, neutral transparent silicone structure glue
    a single component, neutral curing, designed for the construction of curtain wall glass structure bonding assembly. It can be easily squeezed out in wide temperatures. Rely on moisture in the air to cure into excellent, durable, high-volume, high-elastic silicone rubber. Product glass does not need to be coated with the bottom, can produce superior bonding.
    3, building structure adhesive
    building structure adhesive because of its excellent performance, widely used in construction installation, decoration, sealing, structural adhesive and other fields.
