Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway paving, and more specifically to a self-adhesive high-performance waterproof and anti-cracking sticker. Background Art
[0002] Anti-crack stickers are mainly used in the construction and maintenance of highways, general highways and urban road pavement bases. After a period of use, cracks often appear between pavement layers. If the cracks are allowed to spread, it will have a great impact on road conditions. In order to avoid this situation, the more advanced method in the industry is to lay anti-crack stickers between pavement layers, thereby effectively inhibiting the cracks from spreading upward.
[0003] Most of the current anti-cracking materials are single-layer structures, such as geotextiles and fiberglass grids, which have poor anti-cracking effects; some also use composite layer structures, but due to the unreasonable selection of layer materials and the unreasonable setting of layers, the use effect of anti-cracking stickers is unsatisfactory. The tensile strength is poor, the toughness and surface viscosity are insufficient, and the construction in a small area around the crack is difficult.
[0004] Therefore, providing a self-adhesive high-performance waterproof and anti-cracking sticker with good adhesion, high hardness, high toughness and high strength is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0011] Preferably, the anti-cracking cloth is polyester glass fiber cloth, and the thickness of the anti-cracking cloth is 0.6 mm to 0.8 mm. Polyester glass fiber cloth has a large tensile strength, can effectively resist the tensile stress at the interlayer cracks, and limit the development of the crack width.
[0012] Preferably, the thickness of the PET isolation film is 0.1 mm to 0.2 mm. The PET isolation film has the characteristics of being waterproof, anti-fouling, and high temperature resistant, thereby increasing the service life of the anti-cracking sticker.
[0013] Preferably, the bonding layer comprises the following raw materials in parts by weight: 30-40 parts of base asphalt, 2-3 parts of liquid nitrile, 3-4 parts of PE particles, 16-18 parts of ABS high-rubber powder, 5.5-6.5 parts of 10# engine oil, 4-7 parts of high-temperature resistant adhesive (butyl rubber), and 25-30 parts of talcum powder.
