Asphalt Waterproof Material Production Equipment

Asphalt Waterproof Material Production Equipmentused to produce asphalt waterproof membranes. The following is its related introduction:

Main types

SBS/APP modified asphalt waterproofing membrane production line: SBS (styrene-butadiene-styrene block copolymer) and APP (random polypropylene) modified asphalt waterproofing membrane has good weather resistance, water resistance and mechanical properties, and is widely used in building roofs, underground waterproofing and other projects. The production line includes raw material storage and transportation system, modified asphalt preparation system, tire base spreading system, coating system, sanding or film covering system, cooling system, curling packaging system, etc. For example, Oriental Yuhong introduced modified asphalt waterproofing membrane production lines from American R&D and Italian Boato to achieve full-process information and automated production 3.

Self-adhesive modified asphalt waterproofing membrane production line: Self-adhesive waterproofing membrane is easy to construct, does not require open flames, has relatively low requirements for the base layer, and is suitable for various complex construction environments. Its production line is similar to the SBS/APP modified asphalt waterproofing membrane production line, but there are some special designs on the coating system and the isolation membrane covering system to ensure the uniform coating of the self-adhesive layer and the good fit of the isolation membrane.

Production process

Raw material preparation: Mix asphalt, SBS or APP modifiers, fillers, additives and other raw materials in a certain proportion.

Preparation of modified asphalt: Heat the asphalt to a certain temperature, add the modifier to stir, mix and react, so that the modifier is evenly dispersed in the asphalt to improve the performance of the asphalt.

Base treatment: Unfold, dry and preheat the base material (such as polyester base, glass fiber base, etc.) to prepare for the subsequent coating process.

Coating and sanding/filming: Evenly coat the modified asphalt on the base, and then sprinkle quartz sand or cover the isolation film according to product requirements to increase the anti-slip and isolation properties of the coil.

Cooling and shaping: The coated coil passes through the cooling device to quickly cool down and shape it, thereby improving the strength and hardness of the coil.

Curling and packaging: Curl the cooled coil, cut it into a specified length, and pack it for storage.

Equipment composition

Asphalt storage and heating equipment: Used to store asphalt raw materials and heat them to a suitable temperature for subsequent processing. Common ones include asphalt storage tanks, thermal oil heating furnaces, etc.

Modifier adding equipment: Accurately measure and add modifiers such as SBS and APP to asphalt to ensure the stable performance of modified asphalt.

Mixing equipment: Fully mix the asphalt and modifier to evenly disperse the modifier in the asphalt to form modified asphalt.

Tire base spreading machine: Spread the tire base material smoothly to ensure uniform tension and speed of the tire base, providing a stable foundation for the coating process.

Coating equipment: Use scrapers, rollers or extrusion to evenly coat the modified asphalt on the tire base to control the coating thickness and uniformity.

Sanding/filming equipment: Sprinkle quartz sand or cover the isolation film on the surface of the coated coil, which is achieved through equipment such as vibrating screens, sanding machines or filming machines.

Cooling equipment: Use air cooling, water cooling or a combination of air cooling and water cooling to quickly cool the coated coil to shape it.

Curling machine: Curl the cooled coil to form a finished coil, and adjust the diameter and tightness of the curling as needed.

Control system: Use PLC, touch screen and other technologies to centrally control and monitor various equipment on the production line, realize automated production, and improve production efficiency and product quality.

Key technology

Automated control technology: Through advanced control systems, realize automated operation, parameter monitoring and fault diagnosis of the production line, improve production efficiency and product quality stability.

Energy-saving technology: Use energy-saving equipment and processes, such as efficient heating systems, waste heat recovery devices, etc., to reduce energy consumption and reduce production costs.

Environmental protection technology: Equipped with environmental protection facilities such as asphalt fume treatment equipment and dust collection devices to reduce pollutant emissions during the production process and meet environmental protection requirements.

Industry application

Building waterproofing: Used for waterproofing projects in roofs, basements, toilets and other parts of industrial and civil buildings to prevent rainwater, groundwater, etc. from penetrating into the interior of the building.

Road and bridge waterproofing: Applied to bridge deck waterproofing and tunnel waterproofing of roads and bridges to improve the durability and service life of roads and bridges and prevent water damage.

Waterproofing of water conservancy projects: used to prevent water leakage in water conservancy projects such as reservoirs, dams, and canals to ensure the safe operation of water conservancy facilities.

Development trend

Intelligence: production lines will become more and more intelligent, with functions such as automatic detection, automatic adjustment, and remote monitoring to improve production efficiency and product quality stability.

Green and environmental protection: use environmentally friendly raw materials, energy-saving equipment and processes to reduce pollutant emissions and achieve green production.

Multifunctionality: develop asphalt waterproofing membranes with multiple functions, such as self-repair, fire prevention, sound insulation, heat insulation, etc., to meet the needs of different fields.
