In construction and infrastructure engineering, waterproofing is one of the key factors to ensure the durability and durability of structures. Asphalt based thick waterproof coating, as an important waterproof material, plays a key role in the waterproofing of roofs and other building surfaces. This paper introduces the preparation method of asphalt based thick waterproof coating and its main application fields.

Preparation method
The preparation of asphalt based thick waterproof coating is a delicate process, which requires reasonable operation and temperature control. Here are the main steps to prepare the paint:

Asphalt melts and dehydrates

First, the asphalt is heated to a molten state and impurities are removed from it through a dehydration process. This step ensures the purity of the paint.

Adding waste rubber powder

The waste rubber powder is slowly added to the melted asphalt, stirring as it is added. This helps to evenly disperse the waste rubber powder and ensures adequate mixing.

Temperature rise

Continue to heat up to ensure that the waste rubber powder is fully integrated with the asphalt. If grinding rubber powder is used, the cooking temperature should be maintained between 180°C and 200°C for about 1 hour. If the waste rubber powder processed by the crusher is used, the boiling temperature should be within 240°C and the time is about 2 hours.

A uniform, thin paste

During the cooking process, the coating will gradually form a uniform thin paste. When the paint is able to produce uniform filaments, it means that the mixing has reached a good state.

Cooling and dilution

Finally, the paint temperature is reduced to about 100°C and then a predetermined amount of gasoline is added for dilution. By mixing evenly, the final product is obtained.

Application field
Asphalt based thick waterproof coating has excellent heat resistance, crack resistance, low temperature softness and water permeability, which is suitable for a variety of construction and infrastructure projects. Here are some of the main application areas:

1. Waterproof roof

This type of waterproof paint is mainly used on the roofs of buildings. It can effectively protect the interior of the building from rain and moisture. Because of its good impervious properties, it is widely used in roofing projects.

2. Places where low temperature softness is required

Asphalt based thick waterproof coating is often used in construction projects in cold areas because of its low temperature and soft properties. It can remain flexible at extremely low temperatures and will not crack, ensuring structural integrity.

3. Places with high adhesion requirements

Due to its thick nature, asphalt-based coatings can be used on both vertical and inclined surfaces, ensuring strong adhesion. This is very important in some projects that require high adhesion, such as Bridges and pools.

4. Affordable

Asphalt based thick waterproof coating is relatively cheap compared to other waterproof methods, and because of its high solid content, the number of brushes is relatively small, so it can save a lot of thinner. This makes it an affordable waterproofing solution.

conclusion
Asphalt based thick waterproof coating is a kind of waterproof material widely used in construction and infrastructure engineering. 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, asphalt based thick waterproof coatings have an important place in the construction industry and will continue to provide reliable waterproof solutions for various projects.
