Synthetic adhesives are composed of a main agent and an additive, and the main agent is also known as the main material, base material or sticky material; Additives include curing agents, diluents, plasticizers, fillers, coupling agents, initiators, thickeners, antioxidants, polymerization inhibitors, stabilizers, complexing agents, emulsifiers, etc., and can also include flame retardants, foaming agents, defoamers, colorants and antifungal agents according to requirements and uses.
Main agent. The main agent is the main component of the adhesive, which dominates the adhesive adhesion performance and is also an important symbol to distinguish the adhesive category. The main agent is generally composed of one or two, or even three polymers, which requires good adhesion and wettability.
Substances that can be used as stickers are:
1.Natural polymers, such as starch, cellulose, tannins, gum arabic and sodium alginate and other plant stickers, as well as bone gelatin, fish gelatin, blood protein gelatin, casein and shellac and other animal stickers.
2.Synthetic resins are divided into two categories: thermosetting resins and thermoplastic resins. Thermosetting such as epoxy, phenolic, unsaturated polyester, polyurethane, silicone, polyimide, bismaleimide, allyl resin, furan resin, amino resin, alkyd resin, etc.; Thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, acrylic resin, nylon, polycarbonate, polyoxymethylene, thermoplastic polyester, polyphenylene ether, fluororesin, polyphenylene sulfide, polysulfone, polyketone, polyphenylene ester, liquid crystal polymer, etc., as well as their modified resins or polymer alloys.
It is the most used type of adhesive.
3.Rubber and elastomers. Rubber mainly includes neoprene, butyl nitrile ethylene propylene rubber, fluorine rubber, polyisobutylene, polysulfide rubber, natural rubber, chlorosulfonated polyethylene rubber, etc.; Elastomers are mainly thermoplastic elastomers and polyurethane elastomers.
4.In addition, there are inorganic adhesives such as silicates, phosphates, and phosphoric acid-copper oxides.

What is Adhesive? What are the types of adhesives?
What is Adhesive? Adhesive is actually a kind of adhesive, which is basically a thick liquid state, which can tightly bond two different materials or objects of the same material together. There are many different types of adhesives in the market, and these adhesives are non-metallic materials.
With the development of science and technology, it has been widely used in people's daily life and industry or other fields. So what are the types of adhesives? Let's follow us to find out.
What are the types of adhesives?
There are many types of adhesives on the market, such as silicone adhesives, epoxy adhesives, rubber adhesives, and construction adhesives. Each type of adhesive is very practical and targeted. In the following, we will introduce several adhesive applications to users.
1. Silicone adhesive.
Mail silicone adhesive is a kind of sealing adhesive in the adhesive, it has strong cold resistance, heat resistance, aging resistance, waterproof and moisture resistance, non-toxic and harmless and other excellent characteristics compared with other adhesives. In recent years, the development of silicone adhesives in China is getting bigger and bigger, and the development is getting better and better. The application is also becoming more and more extensive.
2. Adhesives for construction.
Construction adhesive is literally an adhesive that is used specifically in construction. With the continuous development of our current and dry economy, people's living standards are improving day by day, and the demand for housing construction is also increasing. This has led to an increase in the production of construction adhesives.
This adhesive is mainly used in the engineering decoration of buildings and the application of sealing or structural engineering.
3. Packaging adhesive.
Packaging adhesive is mainly an adhesive used in factory packaging to bond product labels. The materials of these products are different, including metal, plastic and wood. That's why we usually use their specific adhesives for this.
4. Epoxy resin adhesive.
Epoxy adhesive has a wide range of applications, can bond a wide variety of materials, and it can bond metal materials. Therefore, it is widely used in various industries such as automobiles, electronics, etc. It can also be used in daily life, non-toxic and harmless, relatively safe and healthy.
Summary: There are many types of adhesives on the market, and the objects that can be bonded by each adhesive are relatively large, and each adhesive will have a special one that is more suitable.
That's all it brings to you: What is an adhesive? What are the types of adhesives? All of it.

Adhesive is a kind of adhesive substance with good adhesion performance, which can tightly bond two or more substances of the same type or different types of materials together with each other. The mold-destroying material of the adhesive is composed of a binder, a curing agent, a toughening agent, a diluent, a filler, and a modifier.
There are four main types of adhesives: thermoplastic, thermosetting, synthetic rubber, and rubber resin.
According to the chemical properties of adhesives, they can be divided into inorganic adhesives and organic adhesives. According to the physical properties of adhesives, they can be divided into liquid, solid and paste adhesives. According to the classification of adhesives, they can be divided into natural adhesives and side-modified synthetic adhesives.
Adhesives can be used in all aspects of daily life and production, such as shoe making, LED aluminum substrate adhesive, automotive interior decoration and so on.
Answer 1, polyurethane adhesive raw materials and epoxy resin adhesive raw materials are toxic, for example, polyurethane curing agents mostly belong to isocyanates, which have high activity and are more harmful to human kidneys. The organotins in the catalyst are toxic or highly toxic chemical raw materials. The amine curing agent in epoxy resin adhesive is also toxic, and the reactive diluent is a toxic or highly toxic chemical raw material. >>>More
Adhesive testing is divided into physical testing and chemical performance testing, physical testing includes adhesion and shear force, peeling force after coating substrate, adhesion, initial adhesion, etc., and chemical testing includes the performance of temperature and temperature change. European standard instrument is engaged in the development and production of stripping machine, adhesive tape testing instruments such as adhesive holding force, peeling force can be set freely peeling interval and other functions, fully in line with the standard test requirements. Adhesive tape testing machine.
Tile adhesive reduces the dependence of traditional construction technology on the process of sprinkling water and soaking bricks in the base layer, and Tibeibel tile adhesive has high bonding strength and fast hardening speed, which can greatly improve the service life and decorative effect of various paving materials. >>>More
Polyurethane adhesives are adhesives that contain urethane groups (-NHCOO-) or isocyanate groups (-NCO) in the molecular chain. It is divided into two categories: polyisocyanate and polyurethane, because it contains highly polar and chemically reactive isocyanate and urethane groups, so it can have excellent chemical adhesion with materials containing active hydrogen, such as foam, wood, leather, fabric, paper, ceramics and other porous materials, as well as metal, glass, rubber, plastic and other materials with smooth surfaces. The hydrogen bonding between the polyurethane and the material to be bonded increases the cohesion of the molecule, resulting in a stronger bond. >>>More
