Embodiment 1

[0029] The epoxy resin formulation is shown in Table 1.

[0030] Table 1 Epoxy Resin Recipe

[0031]

[0032] Preparation Process:

[0033] Add acrylic epoxy resin, polyurethane epoxy resin and rubber epoxy resin in weight percentage to the reaction pot, raise the temperature to 70°C, control the temperature to 70°C±5°C, stir and react, after the reaction is complete, cool the reaction pot materials to 50°C, high-speed dispersion for 0.5h to obtain epoxy resin.

[0034] Examples 2-6 bonding materials, the formulations are shown in Table 2.

[0035] Table 2 embodiment 2~6 the component charging percentage of bonding material

[0036]

[0037] Preparation Process:

[0038] Mix and stir the epoxy resin prepared in Example 1 with curing agent, toner and quartz sand for 3-4 minutes to prepare the anti-skid thin-layer adhesive material for road surface.

Embodiment 7

[0039] The construction steps of embodiment 7 pavement antiskid thin layer:

[0040] 1) Clean the cement pavement or steel plate surface, and grind the surface rough,

[0041] 2) Apply the anti-skid thin-layer bonding material for road surface of Examples 2 to 6 on the cement road surface, asphalt road surface or steel plate surface,

[0042] 3) Sprinkle natural special stones or ceramic granules on the surface of the bonding material in step 1) to form a 5mm±1mm colored thin-layer anti-skid road surface.

Embodiment 8

[0043] Embodiment 8 performance test

[0044] Performance index test, except for the method indicated in the table below, the rest are tested according to the method in the traffic industry standard "Pavement Anti-skid Coating" (JT / T712~2008), the test results are shown in Table 3

[0045] Table 3 performance test results

[0046]

[0047] *Chemical corrosion resistance: After making the anti-slip thin layer with the adhesive materials of Examples 2-6, soak the thin layer with gasoline, kerosene, strong acid, strong alkali, xylene, etc. for 24 hours, and observe that there is a change.

[0048] **Low temperature crack resistance: After the adhesive materials of Examples 2-6 are made into anti-skid thin layers, the thin layers are kept in an environment of -10°C for 4 hours, and then stored at room temperature for 4 hours. After one cycle and three consecutive cycles, observe whether there are cracks, etc.

Abstract

The invention discloses a binding material of an anti-skidding layer of a road surface and a preparation method. The binding material is composed of the following components in percentage by weight: 40%-60% of epoxy resin, 15%-25% of a curing agent, 0.5%-1% of toner and 24%-35% of quartz sand. The binding material has excellent mechanical performance, deformation performance and endurance quality and has a consistent color.

Description

technical field [0001] The invention relates to a bonding material for an anti-skid layer for road surfaces and a preparation method thereof, in particular to a bonding material for a colored anti-skid layer for road surface engineering and traffic safety and a preparation method thereof. Background technique [0002] In recent years, my country's road construction, especially expressways, has developed rapidly. The improvement of road grade, the increase of traffic volume and the acceleration of vehicle speed put forward higher requirements for the anti-skid performance of highway pavement. The "Technical Standards for Highway Engineering" (JTJ01-88) promulgated and implemented by the Ministry of Communications stipulates that the road surface should have good stability and sufficient strength, and its surface should meet the requirements of smoothness, compactness and anti-skid. There is a certain gap in the skid resistance index of existing highways, especially highway p...
