The concept of binder
The adhesive is a chemical used to glue, bond, or fix materials by bonding two or more materials together to form a strong bond. Adhesives are usually viscous liquids or solids that fill the voids between materials and form strong chemical bonds when cured to hold materials together. There are many kinds of adhesives, and different kinds of adhesives have different chemical compositions, physical properties, and scope of application, and need to be selected and used according to actual needs.
Classification of binders
According to the composition and properties of the binder, it can be divided into the following categories:
Organic binder: The organic adhesive is mainly composed of organic polymer materials, such as acrylate, polyamide, polyethylene, polypropylene, polyurethane, etc. Organic adhesives have good plasticity, tensile strength, and corrosion resistance, and are suitable for bonding various materials.
Inorganic binders: Inorganic binders are mainly composed of inorganic materials such as silicates, sulfates, aluminates, and alumina. Inorganic binders have excellent high-temperature resistance, corrosion resistance, and good compressive strength, and are suitable for bonding metals, ceramics, glass, and other materials.
Hybrid binder: The hybrid binder is a binder made of a mixture of organic and inorganic materials. It has the advantages of both organic and inorganic binders and is suitable for bonding various materials.
Self-adhesive: Self-adhesive is a self-adhesive material with an adhesive function, which can directly bond two materials together without additional adhesive. Self-adhesives are mainly made of materials such as polymers, resins, glues, and rubbers, and have good adhesive properties and viscosity.
The performance of the binder
The performance of the binder mainly includes the following aspects:
Viscosity: Viscosity is an important physical property of the adhesive, which determines the fluidity, coating, and adhesive properties of the adhesive. The higher the viscosity, the higher the tack and bond strength of the adhesive.
Curing time: Curing time refers to the time required for the adhesive to fully cure from the coating. The shorter the curing time, the more efficiently the adhesive will work.
Durability: Durability refers to the adhesive strength and adhesive stability that the adhesive can maintain under different environments and conditions. Adhesives with good durability can maintain bonding strength for a long time and are not easy to age and embrittle.
Adhesive strength: Adhesive strength refers to the maximum tensile force or shear force that the adhesive can withstand after bonding the material. The higher the bond strength, the better the bonding performance of the adhesive.
Heat resistance: Heat resistance refers to the adhesive strength and adhesive stability that the adhesive can maintain in a high-temperature environment. Adhesives with good heat resistance can maintain adhesive strength for a long time under high-temperature conditions and are not easy to soften and melt.
Application of binder
Adhesives are widely used in various fields, the following are some common application scenarios:
Construction field: In the construction field, adhesives are widely used in the installation and bonding of ceramic tiles, floors, stones, walls, and other materials.
In the field of automobile manufacturing: In the field of automobile manufacturing, adhesives are widely used in the bonding and fixing of parts such as the body, interior, and chassis.
Electronic field: In the electronic field, adhesives are widely used in the bonding and fixing of circuit boards, semiconductors, displays, and other devices.
In the field of medicine: In the field of medicine, adhesives are widely used in the production of medical supplies such as drug preparations and patches.
Manufacturing field: In the manufacturing field, adhesives are widely used in the bonding and fixing of parts in the manufacturing fields of machinery, aerospace, ships, and rail transit.
Market Prospect of Adhesive
With the continuous development and innovation in various fields, the market demand for adhesives is also increasing. Especially in construction, automobile, electronics, medicine, and other fields, the application range of adhesive is more and more extensive, and the market prospect is very broad.
It is expected that in the next few years, with the continuous advancement and upgrading of technologies in various fields, the adhesive market will continue to maintain good growth momentum. According to market survey data, the global binder market will grow from US$180 billion in 2021 to around US$240 billion in 2026, with a compound annual growth rate of more than 5%.
As an indispensable material in modern production and life, the application of adhesives is becoming more and more extensive, and the market prospects are also becoming broader and broader. We need to further promote scientific and technological innovation and technological progress, and continuously improve the quality and performance of binders to meet the needs of various fields and contribute to economic and social development.
At the same time, we also need to pay more attention to environmental protection and sustainable development and promote the green transformation and upgrading of the binder industry to promote the construction of ecological civilization and the realization of sustainable development.
