Asphalt felt paper is mainly used as an isolation layer and temporary protective layer material in waterproof construction to prevent damage to the finished waterproof layer during construction. It is widely used for waterproofing and moisture-proof treatment of roofs, basements, walls, floors and other parts. In addition, oil felt paper can also be used for moisture-proof protection of pipe galleries, packaging materials, and the lower layer of multi-layer waterproof layers. Oil felt paper should be stored in a dry and ventilated environment, avoiding direct sunlight and rain. During transportation and storage, care should be taken to prevent damage or deformation.

The production process of asphalt felt paper mainly includes preparing raw materials (such as asphalt, paper, accelerators, stabilizers, etc.), operating equipment (such as asphalt melting pot, coating mixer, rolling mill, etc.), and specific process flow. During the production process, various raw materials are mixed in proportion, stirred evenly by a mixer, and then pressed into rolls or processed into felt paper of the required thickness by a rolling mill. Subsequently, the oil felt paper is subjected to heating, embossing, and other treatments to increase its anti slip performance and aesthetic appeal. Finally, the processed felt paper is cut and packaged to complete the production process.

Asphalt glass cloth and felt are widely used in waterproofing projects in fields such as construction, transportation, and water conservancy. For example, in waterproofing treatment of roofs, basements, tunnels, bridges, and other areas, asphalt glass cloth and felt play an important role. In addition, it can also be used to make waterproof materials such as waterproof rolls and waterproof coatings. In the production process, glass fiber fabric is first prepared, and then asphalt is uniformly coated on the glass fiber fabric through impregnation process. After a series of treatments such as heating, rolling, etc., asphalt is tightly bonded with glass fibers to form a roll with a certain thickness and strength.

Performance characteristics

Excellent waterproof performance: Due to the excellent waterproof properties of asphalt, asphalt glass cloth felt can effectively prevent water infiltration and protect buildings from water damage.

Corrosion resistance: Glass fiber and asphalt both have good corrosion resistance, which can resist the erosion of various chemicals and extend the service life of materials.

High temperature resistance: Asphalt can still maintain good stability at high temperatures, so asphalt glass cloth felt also has high temperature resistance and is suitable for waterproofing projects in some high-temperature environments.

High strength: The addition of glass fiber significantly improves the strength of the material, enabling it to withstand certain external forces and impacts.
