product description

 

Non-curing rubber asphalt waterproof coating is a new environmentally friendly, high solid content hot melt asphalt waterproof coating. It has the characteristics of not curing after long-term contact with air, and always maintains a viscous gel. It has strong self-healing ability, and it is sticky and difficult to peel. It can solve the cracking and fatigue of waterproof layer caused by the cracking stress of the base layer. The problem of premature aging under damage or high stress; at the same time, the viscosity of the creeping material makes it possible to close the pores and cracks of the base layer well, solve the problem of water repellency of the waterproof layer; The problem of poor compatibility when used in combination with waterproof coatings is a new type of waterproof coating with multiple functions.

 


 

Features

 

Never cure: the cured product contains up to 99%, almost no volatiles, and remains in the original state after construction;

 

Long-lasting bonding: the material remains adhesive after construction, and the bonding effect lasts for a long time;

 

Durable seal: a long-lasting viscoelastic state that ensures a permanent seal of the material to the substrate;

 

Strong adhesion: after special bonding, it can bond with any foreign matter;

 

Dual function: not only a waterproof layer, but also an excellent bonding layer;

 

Flexible viscoelastic: good flexibility, high elongation, suitable for base layer deformation;

 

Strong self-healing: even if the waterproof layer is damaged during construction, it can repair itself and maintain a complete waterproof layer;

 

Wide range of applications: It can be applied at room temperature or in low temperature environment.

Construction process

 

Composite coil construction process:

 

Base treatment → detail engineering → spraying → scribing construction → paving coils → paving and reinforcing lining materials → quality inspection → quality acceptance → protective layer construction

 

Construction requirements:

 

Clean the base layer to make the base layer smooth and solid, free of dust and debris, and no clear water.

 

Start the matching hot-melt heating equipment and heat the non-cured rubber asphalt waterproof coating to the molten state. The heating temperature varies depending on the climate and other conditions. The reference temperature is 150~160°C.

 

The molten non-cured rubber asphalt waterproof coating is pumped or placed in a paint bucket.

 

Spray or scrape according to engineering requirements, 1mm thickness reference dosage: 1.3~1.5Kg/m3.

 

Before the non-curing rubber asphalt waterproof coating is cooled, the waterproofing membrane is compositely laid in time.
