Xinyi Century Building Materials: Composition of Structural Adhesives

We use our excellent technology, the best quality products and the most sincere service to let our customers cooperate with us with confidence! Structural adhesives are commonly used in the bonding of engineering structural components, also known as engineering/structural adhesives, and are a class of adhesives that can withstand many stresses during the rated time without being damaged. The structural adhesive is mainly used for the bonding of the structural members, can withstand large loads, has good mechanical strength at working temperatures above normal temperature, and is resistant to chemicals and other media, chemicals and other media. Anti-aging and other characteristics are the types of adhesives used in the industry. Bonding joints made with such adhesives typically have a level of load comparable to that of the adherend during use, and in all cases, the structural adhesive bond should have a durability that is longer than the expected life of the structure.
The structural adhesive generally uses a thermosetting resin as a binder, a thermoplastic resin or an elastomer as a toughening agent, a curing agent and the like, and some fillers, a solvent, a diluent, a coupling agent, a curing accelerator, and a suppression. Corrosion and anti-oxidation oxidants. The performance of the adhesive depends primarily on the structure, proportion and compatibility of these components.
Engineering/structural adhesives include epoxy glue, polyurethane glue, acrylate glue, anaerobic glue, organic silica gel, etc. The above-mentioned rubber types are mostly reactive types, and can be cured by a chemical reaction at room temperature without using a solvent. At present, there is no consensus on the definition, classification and evaluation criteria of structural adhesives at home and abroad, and the views of various industries are not the same. When classifying and defining structural adhesives and non-structural adhesives, the adhesives used for bonding components that are subjected to strong parts are generally referred to as structural adhesives, and the adhesives used for bonding components that do not need to withstand strong parts are called adhesives. Non-structural adhesive. However, since the same adhesive can be used in strong parts or in non-strength parts, a more rigorous method is to define and classify the properties of the adhesive. American Aerospace Structural Adhesive Standard MMM-A-132 has different heat resistance requirements according to the flight speed of Mach number. The structural adhesives are divided into four types, and shearing, fatigue, creep, aging, T-peeling, etc. The strength indicators have been specified. The flight speed corresponding to type I is less than 1 Mach, and the strength index at room temperature and 82 °C is specified; the type II corresponds to Mach 1 to 2, and the strength index at room temperature and 149 °C is specified; the type III and IV correspond to Mach 2 Above the above 3 Mach, the strength index of room temperature, 149 ° C and 260 ° C is specified. The latter three types are high temperature structural adhesives for supersonic aircraft.
