What are the applications of the waterborne epoxy that has always been advocated?

With the maturity of production technology and the accelerated development of application products, water-based epoxy has gradually emerged its characteristics and advantages.

1.

The water-based epoxy floor coating has the same performance as the solvent-based epoxy floor coating, and is not affected by weather changes.

Features:

2.

The water-based epoxy interior wall is resistant to alkalis, mildew, bacteria, scrubbing, and can be washed.

In fact, the performance, production process, construction process and precautions of water-based epoxy interior walls are exactly the same as those of water-based epoxy floors.

The base surface is required to be a cement base surface.
If it is an ordinary putty or latex paint approved, it must be thoroughly polished to the cement base surface before doing it.
If the water-based epoxy interior wall is directly applied, the serious consequences of peeling and peeling will surely occur.
The putty for repairing must use water-based epoxy putty instead of ordinary internal and external wall putty
.

Three, water-based epoxy non-vibration anti-skid lane

The water-based epoxy non-vibration non-slip ramp has many excellent properties such as durability, non-slip and wear-resistant, tire protection, tire noise reduction, comfort and vibration-free, self-cleaning in rain, etc.
, and the pattern is beautiful and clear, strong in guidance, eye-catching and safe
.
It is very suitable for entrance and exit ramps of underground garages with large slopes and many bends.
The construction process of water-based epoxy non-vibration non-slip rate road includes base surface treatment, base coating port transportation, repair, compression layer construction, layout marking, Anti-slip layer construction, cleaning masking paper, surface coating construction and maintenance
.

Four, water-based epoxy anti-corrosion

Waterborne epoxy substrate having excellent anti-adhesion, chemical energy, good alkali resistance, hard coat, etc.
, suitable for coating containers, trains, ships, storage tanks and the like
.
Water-based epoxy anti-corrosion has very different requirements for different applications.
Therefore, in addition to choosing a very high-quality water-based epoxy resin and water-based epoxy curing agent, water-based epoxy anti-corrosion must also pay attention to the selection and matching of functional anti-corrosion fillers
.
By adding different fillers, it can be made into water-based epoxy zinc-rich primer, water-based epoxy iron oxide red primer, water-based epoxy zinc sulfate anti-rust primer, water-based epoxy mica intermediate coating, and water-based epoxy anti-corrosion mat Top coat and so on
.

Water-based epoxy anti-corrosion during the coating process should pay great attention to the coating of the primer and the control of the humidity of the coating environment.
Because water-based epoxy anti-corrosion itself contains water, the surface of the steel plate is prone to rust during the coating process, and the steel plate is painted as soon as possible after sandblasting.
The first primer and the first primer should be as thin as possible to let the water volatilize as soon as possible, reduce the residence time of the water on the steel plate and reduce the possibility of corrosion.
At the same time, choose the time period when the environmental humidity is low to avoid rainy and foggy days in the morning.
Wait for a period of time and maintain good ventilation
.

Since the waterborne epoxy resin and waterborne epoxy curing agent in waterborne epoxy anticorrosion contain hydrophilic substances in order to achieve good water dispersibility, this will inevitably reduce the water resistance of waterborne epoxy anticorrosion, so the water resistance of waterborne epoxy anticorrosion The two indicators of performance and salt spray resistance are very important.
Waterborne epoxy anticorrosion and salt spray resistance are generally required to reach more than 500 hours
.

Five, water-based epoxy adhesive

Waterborne epoxy adhesives are known for their high bonding strength among various resins.
They have strong bonding power with various materials such as metal, glass, cement, wood, plastics, etc.
, especially those with high surface activity.
Materials with low resistance, such as polyethylene, polypropylene, air-breathing materials, etc.
occupy a small amount of relay, and must be surface activated first).
For different processes and applications, there are room temperature curing agents and heating curing, and heating curing water-based Epoxy resin and water-based epoxy curing agent can be used for a long time, which is suitable for assembly line production
.

Application example:

Waterborne epoxy joint king is a new type of adhesive that connects the gaps of objects.
It has strong crack resistance and adhesive adhesion, strong wear resistance, good water resistance.
Corrosion resistance, color impermeability, safety and environmental protection, and superior accumulation Performance, simple construction, moderate curing time can quickly shape, normal temperature 20-25 ℃ within 2 hours, hard work 24 hours, three days to reach the best hardness
.
After drying, a high-density, high-strength mesh coating is formed at the joint
.

6.
Water-based epoxy cement mortar (concrete)

The water-based epoxy cement mortar (concrete) additive is composed of water-based epoxy resin and water-based epoxy curing agent, and has good compatibility with cement mortar (concrete)
.
When added to mortar (concrete), a high-performance organic-inorganic composite material system with a spatial network structure is formed through the cross-linking and curing of water-based epoxy and the hydration of cement, which plays a role of reinforcement, impermeability and chemical resistance , It can be cured quickly in the wet interface and environment without cracks.
It is suitable for repairing and bonding defects in water conservancy, underground civil air defense projects, roads and bridges, and can also be used as an anti-seepage material
