Epoxy resin adhesive, also known as AB adhesive
1
Epoxy concept:
It refers to the polymer with more than one epoxy group in the molecule and low molecular weight
In a broad sense, it is any epoxy compound with more than one epoxy group and can form a three-dimensional network structure under the action of curing agent

2
Characteristics of epoxy resin:
(1) good process performance;
⑵ high bonding strength;
(3) excellent medium resistance;
(4) good electrical insulation performance;
(5) small shrinkage

3
Composition of epoxy resin:
Epoxy resin adhesive is mainly composed of epoxy resin and curing agent
Toughening agent, diluent and filler are often added to meet different purposes

4
Structure of epoxy resin:
Epoxy resin itself is a compound with thermoplastic linear structure and can not be directly used as adhesive
Curing agent must be added and cured under certain conditions to form a non fusible network structure

5
Purpose:
Epoxy resin adhesive is widely used
It can bond various metals and alloys, ceramics, glass, wood, paperboard, plastics, concrete, stone, bamboo and other non-metallic materials
It can also bond between metal and non-metallic materials
It has no adhesion to untreated polyethylene, polypropylene, polytetrafluoroethylene, polystyrene, polyvinyl chloride and other plastics
It has no adhesion to rubber The bonding ability of soft materials such as leather and fabric is also very poor
In addition to bonding (ordinary bonding and structural bonding) In addition, epoxy resin adhesive can also be used for casting, sealing, caulking, plugging, anti-corrosion, insulation, conductivity, fixation, reinforcement, repair, etc
it is widely used in aviation, aerospace, vehicles and ships, railways, machinery, weapons, chemical industry, light industry, water conservancy, electronic and electrical, construction, medical treatment, sporting goods, arts and crafts, daily life and other fields
ab epoxy adhesive is mixed in the proportion of 1:1 A: B = 1:1; moreover, AB epoxy adhesive has a variety of different curing times
The curing time is different, and the operable time is also different
Here are some examples of Xinwei AB epoxy adhesive as a reference
1
5 minutes surface drying: mix agent a and agent B 1:1, stir evenly, and use up within 2 minutes
2
30 minutes surface drying: mix agent a and agent B 1:1, stir evenly, and use up within 10 minutes
3
60 minutes surface drying: mix agent a and agent B 1:1, stir evenly, and use up within 20 minutes
4
120 minutes surface drying: mix agent a and agent B 1:1, stir evenly, and use up within 60 minutes
5
240 minutes surface drying: after mixing agent a and agent B 1:1, stir them evenly and use them within 120 minutes precautions 1
The working room and appliances must be kept clean, otherwise the glue quality and bonding effect will be affected, especially the oil stain and dust will affect the transparency and adhesion of glue dropping
The indoor humidity should not be too high
Try to keep ventilated or have exhaust fan for personnel to leave Try to wear slippers or shoe covers when moving
When the indoor air is too turbid, sprinkle a small amount of water droplets on the ground
2
The glue dropping workshop shall maintain a normal temperature of 25 ℃ as far as possible
The temperature has a great impact on the usable time and curing time of the glue
In addition, when the air conditioner is turned on, pay attention to the phenomenon that the air outlet mist directly falls on the surface of the adhesive layer and reacts with the composition of agent B, resulting in white fog, oil stain, granular and so on
3
The glue dropping workbench shall be as stable as possible to avoid glue flow, glue exposure, improper dripping and uneven dripping
The balance instrument and balance ruler can be used for debugging first
4, temperature has a greater impact on curing of the product
When the temperature rises, the curing time will accelerate
With the temperature decreasing, the curing time will be prolonged
If the temperature is too high, it will not be used
It will damage the glue property and cannot restore the original
The cured products can not be baked at high temperature for a long time, generally not higher than 110 degrees
The aging test is baked at 65 degrees or so
Just observe for a few hours
5
The glue must be sealed and stored in a cool and ventilated place to avoid high temperature or sunlight
The yellowing is largely due to the fact that the glue is not resistant to UV in sunlight or exceeds a certain exposure time
6
The glue must be mixed strictly according to the weight ratio
If there is too much agent B, it will accelerate the curing and make the glue hard or even dry; if there are too few components of agent B, the curing speed will slow down and make the glue soft or even dry
7
The general shelf life of this kind of glue chemical is 6-8 months
If any component is found to precipitate within the shelf life, please stir it evenly before using or replacing it
8
If there is edge closing after dripping, wipe the surface dirt and oil stain with acetone or toluene first, or spray oil first and then drip glue
This kind of glue (including PU) is composed of oily materials
During the mixing of color paste and toner, it is necessary to add oily material components, otherwise delamination will occur
9
When mixing the glue dropping ratio, the mixing shall be appropriate, not too fast or too fierce
It shall be mixed evenly along the wall slowly
Full mixing can make the chemical reaction more sufficient, the fluidity better, and it is also conducive to better defoaming
10
It is forbidden to pour the unused glue back into the original large barrel packaging
The impurities brought in will scrap the whole barrel of glue
200g glue AB is the best for each opening
Too much reaction will concentrate more energy, shorten the service time and poor fluidity
