Embodiment 1

[0028]With reference to 1, a kind of road crack repair of the present embodiment uses the seam tape and the seam material made of mesh crack paste, including petroleum asphalt, SBS styrene thermoplastic elastomer, rubber powder and additives, said petroleum asphalt, SBS benzene The total content of ethylene thermoplastic elastomer and rubber powder is 85-90%. Road petroleum asphalt is used as the main material. SBS styrene thermoplastic elastomer has the advantages of both rubber and plastic, and has tensile properties and good low temperature resistance. , air permeability, solubility, flexibility, elasticity, heat resistance and unique skid resistance, rubber powder is waste heavy-duty bias tire tread processing powder, which helps to improve wear resistance, fatigue resistance and Tear strength and other properties, but also greatly relieve the pressure of waste tires on environmental protection. The content of the additive is 3%-5%. The additive includes carbon black, anti...

Embodiment 2

[0033] A single-film seam tape, which is made of the above-mentioned seam tape for repairing road cracks and the seam material, the single-film seam tape includes upper, middle and lower layers, and the upper layer is made of easily weathered black The skin type pe film, the middle layer is the seam material made of the road crack repairing seam tape and the mesh crack paste, the lower layer is a black PET release film, the thickness of the black PET release film is 0.036mm, the pe film and The total thickness of the PET release film is less than 0.05mm, and the total thickness of the PE film and the PET release film is less than 0.05mm. This thickness is less than 2.5% of the total thickness of the seam tape, so it can be ignored. When using a single-film seam tape to repair road pavement cracks, there is no need to heat or apply any material on the road surface. After removing the 0.036mm PET release film, paste the cracks and compact them to complete the repair of road pavem...

Embodiment 3

[0035] A double-film seam tape, using the above-mentioned seam tape for repairing road cracks and the seam material made of mesh crack paste, the double-film seam tape includes upper, middle and lower layers, and the upper and lower layers are black PET release film, the middle layer is the seam material made of seam tape and mesh cracking paste for road crack repair, the thickness of the black PET release film is 0.036mm, and the total thickness of the two layers of black PET release film is 0.072mm , this thickness is almost negligible compared to the conventional thickness not less than 2mm. When using double-film seam tape to repair cracks on the road surface, there is no need to heat or apply any material on the road surface. After removing the 0.036mm PET release film, paste the cracks and compact them to complete the repair of road pavement cracks Treatment, the treatment process is: clean the cracks, remove the lower layer of PET release film and then stick it for comp...

Abstract

The invention relates to a crack sealing material prepared from a crack sealing tape for road crack repairing and a net crack sticker. The sum of the content of petroleum asphalt, the content of SBS styrene thermoplastic elastomer and the content of rubber powder is 85-90%. The road petroleum asphalt is used as a main material, the SBS styrene thermoplastic elastomer has the advantages of both rubber and plastic and has tensile property, good low-temperature resistance, air permeability, solubility, flexibility, elasticity, heat resistance and unique skid resistance, and the rubber powder is waste heavy-load diagonal tire tread processing powder, is beneficial to improving the wear resistance, fatigue resistance, tear strength and other properties, and greatly relieves the pressure of waste tires on environmental protection. By means of the high-molecular structure and the polymerization capacity of an environment-friendly synthetic high-molecular polymer, all the components of the crack sealing material prepared from a crack sealing tape for road crack repairing and a net crack sticker can be kept in a uniform mixed state for a long time, precipitation and separation are not likely to happen, and long-term stability of the performance of the crack sealing material prepared from a crack sealing tape for road crack repairing and a net crack sticker is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of repairing materials for various cracks in highway roads, in particular to a jointing material made of seam tape and mesh cracking paste for repairing road cracks. Background technique [0002] Road seam materials are mainly used for minor and small cracks or network cracks (cracks) in preventive road pavement maintenance. The use process is as convenient as adhesive tape sticking things. The types of cracks that can be treated include: transverse cracks, longitudinal cracks, various bending cracks, cracks, mesh cracks, joint surface sealing, etc. Other crack applications such as joint facades of new and old roads, pothole repair facade joint surfaces, etc. Applicable scenarios include: highway pavement, national road pavement, provincial road pavement, county road pavement, municipal road pavement, urban road pavement, rural road pavement, park road pavement, community road pavement, new and old road pave...
