YN self-adhesive anti-crack patch is a high-performance material designed to prevent cement concrete slab expansion joints (cracks) from being eroded by surface water. Its unique structure and material properties make it perform well in isolating surface water erosion, ensuring the stability of the foundation and extending the service life of the road.
1. Material properties and structural design
YN self-adhesive anti-crack patch is composed of reinforced fiber material and high-performance viscoelastic material. Reinforced fiber material has good folding resistance and ductility, and can effectively resist stress concentration when cracks are deformed. The high-performance viscoelastic material covered on the top and bottom gives the anti-crack sticker excellent self-adhesive sealing performance. This material combination enhances the mechanical properties of the anti-crack sticker and also ensures its stability and durability under various environmental conditions.
2. Self-adhesive sealing performance
The self-adhesive sealing performance of the YN self-adhesive anti-crack patch is the key to its isolation of surface water erosion. When the anti-crack sticker is attached to the expansion joint of the cement concrete slab, its viscoelastic material can fit tightly to the crack surface to form a continuous sealing layer. This sealing layer can effectively block the penetration of surface water, prevent water from entering the concrete through cracks, and avoid the erosion and damage of water to concrete.
3. Anti-up and down shear performance
In actual applications, cement concrete slabs will be repeatedly sheared up and down within a certain range under the influence of factors such as vehicle load and temperature changes. The reinforced fiber material of the YN self-adhesive anti-crack patch has good flexural resistance and ductility, and can remain intact under these shearing effects and is not easy to break. Its viscoelastic material can maintain good self-adhesion, ensure the close fit between the anti-crack sticker and the concrete surface, and enhance its ability to isolate surface water erosion.
4. Low-temperature flexibility and anti-perforation performance
YN self-adhesive anti-crack patch also has good low-temperature flexibility and anti-perforation performance. In a low-temperature environment, the anti-crack sticker can maintain its flexibility and elasticity, and will not crack brittlely due to temperature changes. Its anti-perforation performance can effectively prevent sharp objects from damaging the anti-crack sticker, ensuring its stability and durability under various environmental conditions.
5. Waterproof sealing performance
When subjected to horizontal thrust from a moving vehicle, the self-adhesiveness and softness of the YN self-adhesive anti-crack patch can ensure its waterproof sealing performance. The anti-crack sticker can fit the crack surface tightly to form a continuous waterproof layer, effectively preventing the penetration of surface water. This waterproof sealing performance can prevent water from eroding the concrete, and can also improve the stability of the foundation and reduce the generation and expansion of cracks.
