What is epoxy resin glue?

epoxy resin adhesive is generally referred to as epoxy resin adhesive. Epoxy resin adhesive is curing by adding epoxy resin curing agent. Especially because it has good physical and mechanical properties, insulation properties, solvent corrosion resistance, high temperature resistance and adhesion properties, used to prepare the epoxy resin adhesive has a "universal adhesive water" reputation, can be widely used in chemical plants, light industry, water conservancy engineering, transportation, mechanical equipment, electronic devices, household appliances, vehicles and aerospace and other industrial applications.

Epoxy resin adhesive structural adhesive classification

A. According to the compressive strength to distinguish structural adhesive can be divided into three levels:

1. The first stage is used for riveting the main bearing structure, which is the structural adhesive;

2. Secondary riveting for secondary bearing structure, as the standard structural adhesive;

3. There is no limit to the tertiary tensile strength, which should all belong to structural adhesives

B. According to the curing temperature, epoxy resin structural adhesives can be divided into four categories:

1. The continuous high temperature curing epoxy resin structural adhesive has high temperature, ductility, temperature resistance and so on. It is generally used for riveting the main bearing structure;

2. Atmospheric curing epoxy resin structural adhesive is usually integrated into the needs of the airport manufacturing industry and developed into rubber seeds, because the aluminum profile appears dislocation etching trend above 120℃, and will increase with the rise of temperature, the strength and ductility of green aluminum alloy after dislocation etching will be reduced. Therefore, the curing standard of riveted aluminum alloy adhesive shall not exceed 130℃/4h;

3. Indoor temperature curing epoxy resin structural adhesive is more widely used. It is very important in the field of civil engineering application, and it is one of the important varieties of modern structural adhesives.

4. Ultra-low temperature curing epoxy resin adhesive is a new kind of adhesive developed and designed in recent years in order to meet the construction requirements of ultra-low temperature projects in winter. It can be constructed and cured at 0℃ or even from -10℃. According to the temperature resistance, the structural adhesive can be divided into three categories: universal (≤80℃), heat resistance (≥150℃) and medium temperature resistance (medium and the front of a middle).

Advantages and characteristics of epoxy resin adhesive

1. Epoxy resin glue is very cheap and affordable.

Its high performance, whether the ground skid resistance wear resistance or compressive strength moisture-proof are very good, and the surface is very beautiful and generous.

2. Epoxy resin glue will have a tendency of fluidity after it becomes soft under the action of the outside.

The average temperature is solid and semi-solid, with a small amount of liquid. Therefore, when applying, we must pay attention to the temperature and ambient humidity of the bedroom to prevent the application of super glue in no suitable area to achieve the actual effect.

3. There are many types of epoxy resin glue for interpersonal communication, and the main uses are not the same.

There are liquid epoxy anticorrosive coating, also have powder wood peptide epoxy anticorrosive coating, also have radiation source curing powder two building coatings. It is vital to master their different uses and their proper placement.

4. Epoxy resin glue is a two-component glue, and has strong versatility, compared with the larger gap has a very good filling effect.

5. The operating environment is not limited, it can be cured at room temperature, but also in the room or outdoor curing, there is no special requirement for the actual operation site, and it can be handmade, but also mechanical construction.

6. Its moisture-proof, acid and alkali resistance and strong alkali resistance, strong acid performance is good, can be used in a variety of flood disasters, wide coverage of use scenarios.

7. The higher the temperature of the actual operation site of epoxy resin glue, the faster and faster the curing, so the larger the one-time preparation of a little better mixture of substances curing faster and faster, and in the curing will also occur exothermic reaction phenomenon.

The use of epoxy resin adhesive

1, glass fiber bonding.

Epoxy resin adhesive is suitable for repairing the body and interior of new power passenger cars, transport vehicles. However, because the glue is particularly sensitive to UV light, it is not recommended to be used outside the hull.

2, the adhesion between wood.

Epoxy resin glue can replace carpenter's strong glue production manufacturing furniture or kitchen cabinets. Compared with carpenter's super glue, the biggest disadvantage of epoxy glue is that it sets faster and fails in emergency situations.

3, wood and metal bonding.

When used with metal composites, epoxy resins with excessive preservatives should be sorted to avoid unnecessary chemical reactions.

4. Raise the anchor screws.

Epoxy resin adhesive can protect the anchor screws from corrosion, improve the tensile strength of the top of the connecting head, and reduce the dry cracking caused by stress sites.

5. Make jewelry.

Epoxy glue is used to make ornaments by attaching photographs to a frame cup and then applying epoxy glue. You can also create a "prompt box" on the coil.
