Self Adhesive Anti-crack Tape is composed of asphalt-based polymer, high-strength tensile base, and high-strength fabric that is resistant to high temperatures and is compatible with asphalt. This product is self-adhesive and easy to construct. It can be directly pasted on cracks. This structure is an organic and comprehensive application of several measures to prevent cracks on highways. It is also an upgraded product for crack prevention and waterproofing on white-to-black highways.
The anti-cracking mechanism of Go Green anti-crack patch:
The anti-crack patch uses reinforced fiber materials with good bending resistance, high tensile strength, and long-lasting anti-corrosion as the base material, and is covered with high-performance viscoelastic materials processed in a special ratio.
Its anti-cracking mechanism is as follows:
1. When the cement concrete cracks and deforms, because the tensile strength of the anti-crack base material is greater than the bonding strength, the originally concentrated stress is dispersed through the anti-crack covering layer, preventing and reducing the possibility of cracks in the asphalt concrete. possibility.
2. When adjacent cement concrete slabs are repeatedly sheared up and down within a certain range, the reinforced fibers used have excellent bending resistance and extensibility, so the anti-crack patch is not easily broken and the original stress of the anti-crack patch is maintained. diffusion function.
3. Because the anti-crack tape has good self-adhesive sealing properties, it blocks surface water from eroding the expansion joints (cracks) of the cement concrete slab, ensuring a stable foundation and reducing the factors that cause cracks.
Features:
1. Excellent anti-cracking effect
The anti-crack tape with a thickness of 2mm can play a very good role in alleviating and dispersing when the two cement concrete plates are horizontally displaced by 1mm (the base joint width is 4mm). After being opened and closed 10,000 times, the anti-crack tape will not be damaged.
2. It has excellent low temperature flexibility and good resistance to up and down shearing.
Since the base material of the anti-crack tape is soft and elastic, the material will not break when bent 180°. When the anti-crack tape bonded to two cement concrete plates moves up and down by 0.5mm (the base joint width is 4mm), after repeated up and down displacements 10,000 times, due to the The crack tape has good flexibility and elongation, and the anti-crack tape is non-destructive (the allowable up and down displacement value in conventional design is generally not greater than 0.06mm).
3. Good bonding performance
The anti-crack sticker has good adhesion with both the cement concrete base and the asphalt concrete surface. Its bonding strength is greater than 4N/mm. After rolling with hot asphalt concrete, the bonding performance is greatly improved. Therefore, when horizontal stress is applied When, it is not easy to cause slippage and damage.
4. Good waterproof and airtight performance
Since the self-adhesive covering layer on the lower surface of the anti-crack sticker is larger than 1mm, after being rolled with hot asphalt concrete, it is completely combined with the cement concrete, which greatly improves the waterproof sealing, prevents surface water from penetrating into the cracks of the cement concrete slab, and improves the foundation's durability. stable. Especially when subjected to the horizontal thrust of a moving vehicle, the covering layer has good self-adhesiveness and flexibility, ensuring waterproof sealing.
5. Convenient construction
The construction method of the anti-crack sticker is self-adhesive cold construction. As long as the isolation paper (membrane) is removed, it can be directly pasted on the treated cement concrete base. The construction is convenient and fast. At the same time, it does not pollute the environment and is environmentally friendly. product.
