Adhesive It is a substance with excellent adhesive properties. It bonds objects together by adhering to surfaces through both adhesion and cohesion.
Introduction to the substance
A class of organic or inorganic, natural or synthetic substances that can join identical or different pieces (or materials) of the same or different natures together and, after curing, exhibit sufficient strength are collectively referred to as adhesives, bonding agents, or—commonly—simply as "glues." These adhesives can be categorized into three main types: natural macromolecular compounds (such as starch, animal hide glue, bone glue, and natural rubber), synthetic macromolecular compounds (including thermosetting resins like epoxy resin, phenolic resin, urea-formaldehyde resin, and polyurethane, as well as thermoplastic resins such as polyvinyl acetals and polyvinyl chloride resins, plus synthetic rubbers like chloroprene rubber and nitrile rubber), and inorganic compounds (such as silicates and phosphates). Depending on specific application requirements, adhesives often contain additional ingredients, including curing agents, accelerators, reinforcing agents, diluents, and fillers.
By application, adhesives can also be categorized into thermal adhesives, sealants, structural adhesives, and more. By application process, they include room-temperature curing adhesives and pressure-sensitive adhesives. Adhesives can join dissimilar materials and thin-sheet materials, and the stress distribution at the bonded joint is uniform. In container manufacturing and repair, commonly used adhesives include epoxy resins, chloroprene rubber, and sealants.
In recent years, organic Adhesive With its increasingly broad range of applications, adhesive bonding technology has now become highly mature and has emerged as one of the three major modern joining techniques—alongside welding and mechanical fastening.
Category
1. According to their application methods, they can be classified into thermosetting, hot-melt, room-temperature curing, and pressure-sensitive types, among others.
2. According to the application target, adhesives can be categorized into structural adhesives, non-structural adhesives, or special-purpose adhesives. Structural adhesives include thermosetting types such as epoxy resins, polyurethanes, organosilicon compounds, and polyimides; thermoplastic types such as polyacrylates, polymethyl methacrylates, and methyl methacrylate-based adhesives; as well as multi-component modified adhesives, such as phenol-epoxy hybrids.
3. According to their curing form, they can be classified into four types: solvent-evaporating type, emulsion type, reactive type, and hot-melt type.
4. Classified by main components into organic and inorganic categories.
5. Classified by appearance, they can be divided into three categories: liquid, paste, and solid.
6. Classified by component: single-component, two-component, reactive.
