With the continuous increase of new varieties of adhesives, the scope of applications is expanding day by day with the anti-correlation theory As the discussion deepens gradually, bonding technology will have broader development prospects, HereWill一一Introduction to various types of bondingAgent. Especially the new adhesive productscategoryand development trends.
AdhesionAgentComposition
Natural adhesives used by people in the early days, such as animal adhesivesfishglue、boneGlue, plant starch、Dextrin, etc.. Use water as the solvent, and the components are very simple. But when people use a large number of synthetichighMolecular compoundsWith Later, in order to meet various requirements, adhesives are mostly composed of a variety of components span>AndInto. These componentsIntroductionAs follows:
（1) adhesiveAlso known as Base material,is glue Agent. It affects the bonding properties of adhesives (such as bonding strength, heat resistance of joints, Aging resistance, etc.) plays a decisive influence.
（2) Curing agentAlso known ashardener, curing agent or stabilizer. CuringAgentYesOneAn additive that can cross-link polymers with a linear structure into a linear structure. For a certainsomeType adhesives (such as commonly used epoxy resin adhesives and room temperature curing phenolicsTreeTree合agent, etc.) is The dosage and performance of an essential component, the curing agent, will directly impact span>gluingThe process performance of the agent(such as glue coating method, Curing conditions, etc.), it will also affect the glueconnectionConnector performance（RujiaoConnectStrength, heat resistance, solvent resistance, etc.).
（3)Toughening agent Toughening agents can improve adhesionhereThe performance of the agent can increase the toughness, reduce the brittleness, and improve the peeling resistance and impact resistance of the adhesive joint structure. According to different types of adhesive, chooseUse different tougheners. Toughening agent and binder must have good compatibility.
（4) ThinnerThinner is A type of component that can reduce the viscosity of adhesive. ItCan increaseAdd glueAgentactual wetting ability on the surface of the adherend, and is beneficial to construction.Where can be used with adhesiveagent span>Miscible solvents or various low-viscosity compounds that can participate in the adhesive curing reaction can be used as DiluentAgent.
（5)Filler Filler can improve the bonding strength of glued joints, span>Increase surface hardness, improve heat resistance, reduce thermal expansion coefficient and shrinkage, increase viscosity and reduce costs, etc. Effect. Using special fillers, special properties can also be obtained, such as electrical conductivity, magnetic permeability, etc.
