In the construction and infrastructure sector, waterproof coatings are a key element in ensuring 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. The preparation method of fatty acid emulsified asphalt waterproof coating and its wide application fields are introduced in this paper.

Preparation method
The preparation method of fatty acid emulsified asphalt waterproof coating is relatively simple, but it is critical to ensure that each step is carefully performed to obtain a high quality coating. Here are the main steps to prepare the paint:

Material preparation

First, it is necessary to prepare two different kinds of asphalt, usually referring to two different viscosity and characteristics of asphalt. In addition, a fatty acid is needed.

Mixed asphalt

The two bitumen are mixed together and heated to a temperature of approximately 115°C to 120°C. This step aims to mix the two bitumen well and ensure that they become operable at high temperatures.

Preparation of alkaline emulsion

On the other hand, alkaline emulsions need to be prepared. This emulsion usually consists of sodium naphthenate, 30% sodium hydroxide, water glass, and water. These components are mixed and dissolved to form an alkaline emulsion.

Add the mixture of bitumen to the emulsion

The preheated asphalt mixture is slowly added to an alkaline emulsion preheated to 60°C to 70°C. This is a critical step to ensure that the two liquids are well combined.

Stir and mix

The two emulsions are put into a blender and mixed at a speed of 50 to 100 rpm. This process requires constant stirring for at least 10 minutes to ensure that all the ingredients are evenly mixed.

Preparation of fatty acid asphalt emulsion

When the mixture is complete, the fatty acid asphalt emulsion is prepared. This emulsion has high dispersion and permeability, stable storage, water resistance and weather resistance.

Application field
Fatty acid emulsion asphalt waterproofing coatings have a wide range of applications and are suitable for various construction and infrastructure projects. Here are some of the main application areas:

1. Waterproof roof

Fatty acid emulsion asphalt waterproof coating can be used on the roof of a building to effectively protect the interior of the building from rain and moisture. This is essential for maintaining the structural integrity of the building.

2. Waterproof basement

Basements are often vulnerable to rising water tables and infiltration. Fatty acid emulsion asphalt waterproof coating can be used for basement walls and floors to prevent moisture penetration and damage.

3. Infrastructure projects

Fatty acid emulsion 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 emulsion asphalt waterproof coating can be used inside cold storage to prevent temperature fluctuations and moisture penetration.

5. Waterproof walls and bathroom

In the walls of buildings and in the toilet bath, waterproof coatings can prevent moisture intrusion into the wall structure, thereby extending the service life of the walls.

6. Rust and corrosion prevention

In addition, the paint can also be used for rust and corrosion prevention of underground pipes, ensuring that these pipes are not corroded in harsh environments.

conclusion
Fatty acid emulsified asphalt waterproof coating is a highly efficient waterproof material widely used in construction and infrastructure fields. Through a reasonable preparation method, its quality and performance can be ensured, so that it can play an excellent waterproof role in various projects. This paint plays an important role in maintaining the integrity of buildings and infrastructure, helping to extend their useful life and reduce maintenance costs. Therefore, fatty acid emulsified asphalt waterproofing coatings have an important place in the construction industry and will continue to provide reliable waterproofing solutions for various projects.
