Description :

　　Self adhesive anti cracking sticker Self adhesive anti cracking sticker/anti cracking sticker (referred to as anti cracking sticker/anti cracking sticker) is a high-performance viscoelastic material that uses reinforced fiber materials with good flexural performance, high tensile strength, and permanent anti-corrosion as the substrate, and is processed with extraordinary proportions for high and low offset protection. When cement concrete cracks and deforms, due to the tensile strength of the "crack prevention sticker" substrate being greater than the adhesive strength, the stress concentrated in the blueprint is separated through the protective layer of the crack prevention sticker, preventing and reducing the possibility of local cracks in asphalt concrete. When adjacent cement concrete slabs are repeatedly cut high and low within a certain scale, the use of reinforcing fibers has excellent flexural and delay resistance. Therefore, it is not easy to break the "crack prevention sticker", maintaining good self-adhesive closure of the "crack prevention sticker", preventing surface water from eroding the expansion joints (cracks) of the cement concrete slab at intervals, and ensuring that the foundation remains unchanged

　　After multiple road trials and field surveys, it has been found that the anti cracking sticker has excellent anti cracking properties. A 2mm thick anti cracking sticker has a tensile strength of ≥ 600N/50mm and a product delay rate of ≥ 30%. When cement concrete cracks and deforms, due to the tensile strength of the "crack prevention sticker" substrate being greater than the bonding strength, the stress concentrated in the blueprint is separated by the cover layer of the crack prevention sticker during the process, preventing and reducing the possibility of local cracks in asphalt concrete. Its excellent low-temperature flexibility provides good resistance to high and low shear forces. When adjacent cement concrete slabs are repeatedly cut high and low within a certain scale, the reinforcing fibers used have excellent flexural and delay resistance. Therefore, it is not easy to break the "crack prevention sticker", and the connection of the "crack prevention sticker" has good self-adhesive closure, which prevents surface water from eroding the expansion joints (cracks) of the cement concrete slab at intervals, ensures the stability of the foundation, and reduces the components that produce cracks. Excellent bonding performance, perforation resistance, and waterproof sealing effectively prevent surface water from penetrating into cracks in cement concrete slabs, advancing the stability of the foundation. Especially when subjected to the degree of thrust from the driving vehicle, the excellent self-adhesive and flexible nature of its cover layer ensures waterproof sealing. Greatly improved waterproofing and anti imprint surface moisture infiltration to prevent the occurrence of cracks in cement concrete slabs, laying a solid foundation for progress.

　　Characteristics of self-adhesive crack prevention tape: 1. Excellent crack prevention tape with a thickness of 2mm called "YN crack prevention tape", with a tensile strength of ≥ 600N/50mm and a product delay rate of ≥ 30%. When the displacement of two cement concrete slabs is 1mm (with a base joint width of 4mm), anti cracking stickers can effectively reduce and slow down the immersion. After opening and closing 10000 times, the "crack prevention sticker" remained undamaged. 2. There is excellent low-temperature flexibility, which can withstand high and low shear performance. Due to the excellent flexibility and elasticity of the "anti cracking adhesive" substrate, it can be used along a 20mm glass rod at a low temperature of -20 ℃. Bend 1800 material without exhaustion or cracking. When the "crack prevention sticker" pasted on two cement concrete slabs has a high and low displacement of 0.5mm (with a base joint width of 4mm), and after several times of three high and low displacement of 10000 times, due to the excellent flexibility and delay rate of the "crack prevention sticker", there is no damage to the "crack prevention sticker" (in conventional design, the allowable high and low displacement values are not more than 0.06mm). 3. Good adhesion performance: "Anti cracking adhesive" has good adhesion with both the lower layer of cement concrete and the surface layer of asphalt concrete. Its adhesion strength is greater than 4N/mm. After being rolled by hot asphalt concrete, the adhesion performance greatly improves, so that it is not easily prone to slip and damage when subjected to force to the same degree. At a low temperature of 50 ℃, the shear strength of the "anti cracking sticker" can reach 0.15Map. 4. The anti perforation "anti cracking sticker" has good resistance to perforation. After being struck by a 500g heavy hammer from a height of 500mm, and then subjected to a constant pressure of 0.3MPa for 0.5h, the "anti cracking sticker" does not leak water. 5. Good waterproof and sealing performance due to the self-adhesive cover layer under the "crack prevention sticker" being larger than 1mm. After being pressed by hot asphalt concrete, it is completely connected to cement concrete, greatly improving waterproof and sealing performance, preventing surface water from penetrating into cracks in cement concrete slabs, and promoting the stability of the foundation. Especially when subjected to the degree of thrust from the driving vehicle, the excellent self-adhesive and flexible nature of its cover layer ensures waterproof sealing. 6. The construction convenience of "crack prevention stickers" is formulated as self-adhesive cold construction. As long as the isolation paper (film) is removed, it can be directly pasted on the treated cement concrete lower layer. Convenient construction and fast speed. At the same time, it is a type of product that does not infect the scenery.

　　Construction technology and precautions for self-adhesive anti cracking stickers

　　1. Comply with the width selection of crack (joint) joints on the road surface and choose the specifications of anti crack stickers used. For cracks (joints) below 1mm-3mm, a minimum of 24cm anti crack stickers should be used; 2. Crack (joint) joints with a width of 3mm to 5mm or less, and use anti crack stickers with a minimum of 32cm. 3. Clean the crack (joint) with a width between 5mm and 19mm, fill it with sealant, and then apply a 48cm crack resistant adhesive to the joint. 4. Clean up the cracks (joints) and sunken areas with a width of 19mm, fill and compact them with adhesive sand, sealant or asphalt assimilates to the existing height, and then use 98cm crack resistant stickers to stick the joints. 5. Cracks or potholes with a width exceeding 50mm should be cleaned up first, then filled with adhesive sand or hot asphalt assimilation material and compacted to the existing height, and then sealed with 98cm crack resistant adhesive tape. 6. For highly divergent cracks (joints) and sunken areas, leveling measures should be taken. Precautions: ⑴ Dry the cement concrete pavement before construction. Construction shall not be carried out on damp substrates or in rainy or snowy weather. ⑵ After construction, use sandbags or rubber tire rollers to compact the "crack prevention sticker" to prevent rainwater from entering the bonding surface of the "crack prevention sticker" before laying asphalt concrete. If it is estimated that there will be heavy rain before paving asphalt concrete, sealant should be used to seal both sides of the "crack prevention sticker". Construction should not be carried out when the temperature is below 5 ℃. During the paving of asphalt concrete, vehicles are not allowed to roll or turn around on the "crack prevention sticker" on the spot. When the slope is greater than 5%, the width of the "crack prevention sticker" should not exceed 330mm. When laying the bottom layer of asphalt concrete, there may be a small amount of slip, which should be repaired in real time without affecting the quality of the project. ⑹ The total thickness of asphalt concrete paving should not be less than 6cm. ⑹ When the height difference between adjacent edges of the "crack prevention sticker" in the temple warehouse is greater than 1cm or there are many pits, the part should be leveled before paving to prevent the "crack prevention sticker" laid in the depression from being damaged by gravity. The leveling material can be epoxy mortar or asphalt assimilation material.
