Adhesive is a substance that binds the adhesive together by means of bonding. Composition of adhesive:
1. Bonding material.
Adhesive material also known as adhesives, it is the basic component of adhesives, play a cohesive role.Its properties determine the performance of the adhesive, use and use conditions. Generally, various resins, rubber and natural polymer compounds are used as binder.
2. The curing agent
Curing agent is the component that causes the adhesive substance to solidify faster through chemical reaction. Some adhesives in the resin (such as epoxy resin) without curing agent, its own can not become a hard solid. Curing agent is also the main component of adhesives. Its properties and dosage play an important role in the performance of adhesives.
3. The toughening agent
Toughening agent is a component to improve the toughness and impact strength of the adhesive layer. Common toughening agents are dibutyl phthalate and dioctyl phthalate, etc.
4. The diluent
Diluent also known as solvent, mainly to reduce the viscosity of adhesive, in order to facilitate the operation, improve the wettability and mobility of adhesive. Common diluent organic solvents are acetone, benzene and toluene.
5. Packing material
Fillers generally do not have chemical reactions in adhesives, which can increase the viscosity of adhesives, reduce the coefficient of thermal expansion, reduce the shrinkage, and improve the impact strength and mechanical strength. Commonly used fillers are talcum powder, asbestos powder and aluminum powder.
6. Modifier
Modifiers are components added to improve the properties of adhesives in order to meet special requirements. For example, coupling agents can be added to increase bonding strength. Preservatives, anti-mildew agents, flame retardants and stabilizers can also be added
