1. Introduction to waterborne epoxy emulsified asphalt products
Waterborne epoxy emulsified asphalt is a new environmentally friendly emulsified asphalt made by mixing epoxy resin emulsified with emulsified asphalt. It has the characteristics of solvent-free, non-toxic, tasteless, and pollution-free, and is a green product. Waterborne epoxy emulsified asphalt has good water resistance, weather resistance, chemical resistance, and excellent adhesion, and can maintain excellent performance in humid and rainy environments for a long time.
2. Characteristics of waterborne epoxy emulsified asphalt products
(1) Water resistance and weather resistance: Waterborne epoxy emulsified asphalt has good water resistance and weather resistance, and can maintain excellent performance in humid and rainy environments for a long time.
(2) Adhesion: With excellent adhesion, it can firmly bond with various materials, improving the skid resistance and durability of the road surface.
(3) Chemical resistance: It has good chemical resistance and can resist the erosion of chemicals such as acid, alkali, salt, and oil, extending the service life of the road surface.
(4) Environmental friendliness: It does not contain heavy metals such as lead, chromium, mercury, etc., and has no toxic effects on the environment and human body, which is in line with the development trend of modern green buildings.
3. Construction precautions
(1) Base treatment: Ensure that the surface of the base is clean and free of impurities such as oil stains and dust, and the moisture content of the concrete base should not exceed 6%.
(2) Construction environment: Avoid construction under conditions where the temperature is below 10 ℃ or above high temperatures, and choose a period of 4 hours without rain or snow for construction.
(3) Coating application and construction: Mix evenly, control the construction thickness and number of coats, and avoid missed or accumulated coating.
(4) Finished product protection and subsequent construction: Pedestrians and vehicles are prohibited from walking before the waterproof layer is fully installed. Subsequent construction should be carried out as soon as it is fully installed.
4. Application fields of waterborne epoxy emulsified asphalt
(1) Road surface repair: used for repairing and repairing road surfaces to improve their durability and skid resistance.
(2) Waterproof coating: a waterproof coating used for concrete structures such as buildings, bridges, tunnels, etc., with excellent waterproof effect.
(3) Primer: Used as a primer to improve the adhesion between the coating and the substrate, and enhance the durability of the coating.
(4) Bridge deck waterproof coating: It performs well in the bridge deck waterproof layer, forming a dense waterproof barrier to ensure the long-term stability of roads and bridges.
5. Future development direction
With the improvement of environmental awareness and technological progress, the performance of waterborne epoxy emulsified asphalt will continue to improve, and its application scope will also continue to expand.
