In the field of construction and infrastructure, waterproof coatings are a key element to ensure the long-term protection of building structures and underground facilities. Fatty acid emulsified asphalt waterproof coating is a common waterproof coating with excellent waterproof performance and durability. This article will introduce the preparation method of fatty acid emulsified asphalt waterproof coating and its wide application field.
The preparation method of fatty acid emulsified asphalt waterproof paint is relatively simple, but it is critical to ensure that each step is carefully performed to obtain a high-quality paint. Here are the main steps to prepare this paint:
Material preparation
First, two different types of asphalt need to be prepared, usually two different viscosities and properties of asphalt. In addition, a fatty acid is required.
Mixed asphalt
Mix the two bitumens together and heat to a temperature of approximately 115 ℃ to 120 ℃. This step aims to mix the two bitumens well and ensure they become operational at high temperatures.
Preparation of alkaline emulsion
On the other hand, an alkaline emulsion needs to be prepared. This emulsion usually includes sodium naphthenate, 30% sodium hydroxide, water glass, and water. These ingredients are mixed and dissolved to form an alkaline emulsion.
Add the mixed asphalt to the emulsion
Slowly add the preheated mixed pitch to the alkaline emulsion preheated to 60 ℃ to 70 ℃. This is a critical step that requires ensuring that the two liquids are fully combined.
Stirring and mixing
Put the two lotions in a blender and mix at 50 rpm to 100 rpm. This process requires constant stirring for at least 10 minutes or more to ensure that all ingredients are evenly mixed.
Preparation of Fatty Acid Asphalt Emulsion
After mixing, a fatty acid asphalt emulsion is obtained. This emulsion has high dispersion and permeability, stable storage, and water and weather resistance.
Fatty acid emulsified asphalt waterproof coatings have a wide range of application fields, suitable for various construction and infrastructure projects. The following are some of the main application fields:
1. Roof waterproofing
Fatty acid emulsified asphalt waterproof coatings can be used on the roofs of buildings to effectively protect the interior of the building from rainfall and moisture. This is critical for maintaining the structural integrity of the building.
2. Basement waterproofing
Basements are often susceptible to rising water levels and infiltration. Fatty acid emulsified asphalt waterproof coatings can be used on basement walls and floors to prevent moisture infiltration and damage.
3. Infrastructure Engineering
Fatty acid emulsified asphalt waterproofing coatings are also widely used in infrastructure projects such as bridges, pools and underground pipelines. These projects often require highly reliable waterproofing solutions to ensure their long-term stability.
4. Cold storage waterproof
Cold storage needs to maintain strict temperature and humidity control. Fatty acid emulsified asphalt waterproof coating can be used inside cold storage to prevent temperature fluctuations and moisture penetration.
5. Waterproofing of walls and toilets
In the walls of buildings and toilets and bathrooms, waterproof coatings can prevent moisture from invading the wall structure, thereby extending the service life of the wall.
6. Anti-rust and anti-corrosion
In addition, this coating can also be used for rust and corrosion prevention of underground pipes, ensuring that these pipes are not eroded in harsh environments.
Fatty acid emulsified asphalt waterproof coating is an efficient waterproof material widely used in the construction and infrastructure fields. Through reasonable preparation methods, its quality and performance can be ensured, making it play an excellent waterproof role in various projects. This coating plays an important role in maintaining the integrity of buildings and infrastructure, helping to extend their service life and reduce maintenance costs. Therefore, fatty acid emulsified asphalt waterproof coating has an important position in the construction industry and will continue to provide reliable waterproof solutions for various projects.
