What is structural adhesive?

　　As an adhesive, the key function of structural adhesives is undoubtedly bonding, but compared with other adhesives, what is the difference between structural adhesives? First, non-structural adhesives have low strength and poor durability. It is only used for general and temporary properties of bonding, sealing and fixing, and cannot be used for parts bonding.

　　 The structural adhesive has high strength, peel resistance, impact resistance and simple construction process. It is used for bonding the same or different raw materials such as metal materials, porcelain, plastics, vulcanized rubber, wood, etc. It can partially replace the traditional connection methods such as electric welding, riveting, and screw connection. The ground stress on the fusion surface is evenly distributed, and there is no thermal hazard and deformation to the parts.

The ground stress on the fusion surface is evenly distributed, and there is no thermal hazard and deformation to the parts.

　　The use of structural adhesives in engineering projects is also very common, used for structural reinforcement of prefabricated components, steel anchoring, bonding, repairing, etc.; such as bonding steel, bonding carbon fiber materials, chemical planting, gap reinforcement, sealing, repairing, etc. Hole, road stud sticking, surface safety protection, bonding, etc.

　　The structural adhesive has high strength, can withstand large loads, is resistant to aging, fatigue, and corrosion, and has stable characteristics within the expected life. Suitable for adhesives that withstand strong component bonding.

　　Structural adhesives are divided into two categories.

　　1. Epoxy structural adhesive

　　epoxy resin structural adhesive is a solution-free, liquid component epoxy resin adhesive that can be cured at room temperature or high temperature. After curing, the layer is at a medium strength, so it can withstand strong shocks and vibrations. This layer has excellent mechanical equipment characteristics, excellent electrical insulation properties, and can withstand temperature changes and tensile strain tear stress. It is non-corrosive and has good adhesion to metal materials, porcelain, rubber materials, glass fiber products and carbon fiber materials.

　　The epoxy resin structural adhesive cures at room temperature without heating or working pressure. It is well known that heating can accelerate its curing. There are no volatile organic compounds during the entire curing process. Generally, glue with a thickness of about 0.8mm can be fully bonded at the bonding seam. When the curing temperature is lower than 15°C, the actual bonding effect will be poor. Cured at 25℃~70℃, the actual bonding effect can be obtained.

　　2, acrylic resin structural adhesive

　　Acrylic resin structural adhesive is a structural adhesive composed of acrylic resin and modified material curing agent. Fast curing, high strength, can be fixed up and down in five minutes. 80% strength can be reached after 30 minutes, and the strength is strong after 24 hours. Excellent corrosion resistance, water resistance, oil resistance, stronger heat resistance and aging resistance, good adhesion to metal materials, better impact resistance than epoxy resin, excellent heat resistance and cold resistance, and operating temperature lower than- 30~150℃.
