Embodiment 1

[0032] A kind of road mesh sticker of the present embodiment comprises a mesh sticker body, and the mesh sticker body includes an adhesive layer 2, a rock layer 3 and an anti-adhesive isolation layer 1, and on the outer surface of the rock layer adhesive layer 2, the anti-adhesive The isolation layer 1 is bonded on the inner surface of the adhesive layer 2 to prevent other sundries from adhering to the inner surface of the adhesive layer 2 and affecting the use; A tire base layer 4 is arranged in the middle of the viscose layer.

[0033] In this embodiment, in order to increase the tensile strength of the viscose layer 2 , a base fabric layer is provided in the middle of the viscose layer 2 .

[0034] In this embodiment, the thickness of the adhesive layer 2 is set to 2 mm, and the thickness of the rock layer 3 is set to 1.5 mm. With such a thickness, the adhesive layer 2 can be completely integrated into the crack without causing a large bumpy feeling when the vehicle is run...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the thickness of the adhesive layer is set to 1.5 mm, the thickness of the rock layer is set to 1.8 mm, and the rock layer is a schist layer.

[0046] In addition, the difference between this embodiment and Embodiment 1 is that the adhesive layer is made of the following raw materials in parts by weight: 50 parts of asphalt, 6 parts of modifier, 9 parts of rubber powder, 7 parts of stabilizer, and 7 parts of thermoplastic resin , 7 parts of coal ash powder. Among them, the modifier is SBS modifier; the stabilizer is organic rare earth; the adhesive is thermoplastic resin.

Embodiment 3

[0048] The difference between this embodiment and embodiment 2 lies in that the thickness of the adhesive layer is set to 2.5 mm, and the thickness of the rock layer is set to 1.3 mm.

[0049] In addition, the difference between this embodiment and Embodiment 1 is that the adhesive layer is made of the following raw materials in parts by weight: 50 parts of asphalt, 6 parts of modifier, 9 parts of rubber powder, 5 parts of stabilizer, 7 parts of adhesive 7 parts, coal ash powder. Among them, the modifier is SBS modifier; the stabilizer is organic rare earth; the adhesive is thermoplastic resin.

Abstract

The invention provides a road net-shaped crack sticker, which comprises a net-shaped crack sticker body, wherein the net-shaped crack sticker body comprises an adhesive layer, a rock layer adhered to the outer side face of the adhesive layer and an anti-sticking isolation layer adhered to the outer side face of the adhesive layer, a tire base cloth layer is arranged in the middle of the adhesive layer, the arranged tire base cloth layer can improve the tensile property of the road net-shaped crack sticker and preventwater from permeating into cracks so as to prevent the adhesive layer from falling off, and the net-shaped crack sticker body serving as a surface layer of a repairing structure can be well bonded with an original road surface and well adapt to crack changes.

Description

technical field [0001] The invention relates to the technical field of seam glue, in particular to a mesh cracking paste for roads and a preparation method thereof. Background technique [0002] After long-term rolling and aging, road pavement is more prone to network cracks. If the pavement cracks are not repaired, it will not only affect the traffic of vehicles, but also make the pavement more likely to be further damaged quickly. At present, there are mainly three maintenance methods for pavement crack maintenance and repair in China: filler crack repair technology and preheating crack repair technology. Cut-and-fill crack repair technology, dig-and-fill crack repair is the most commonly used maintenance method in highway minor repairs and maintenance. It is to use a special tool cutting machine to completely divide the joint between the diseased pavement and the good asphalt pavement for irregular disease cracks. Cut into regular rectangles or squares, and thoroughly t...
