Problems solved by technology

For example, in U.S.Pat.3,012,487, pine tar is used as a co-solvent for epoxy resin and asphalt, and diethylenetriamine, phthalic anhydride, etc. are used as curing agents to successfully prepare epoxy asphalt bonding materials and apply them to concrete surfaces. And in the roadbed, a hard, rough, solvent-resistant anti-skid coating is obtained. Obviously, pine tar remains in the system as a solvent, which has a great impact on the performance of the material, and the obtained product is hard and brittle; U.S. Two active co-solvents were synthesized in Pat.4,360,608, and the situation of using phenols (such as nonylphenol, etc.) Phase, but the bending strength is low; U.S.Pat.: 4,139,511 uses a small amount of maleic anhydride (5%, 10%) or maleic anhydride ester to modify asphalt at high temperature, and found that the obtained asphalt is compatible with epoxy The resin has good compatibility.

Embodiment 1

[0023] Example 1: Add 30 parts of succinic acid, 25 parts of adipic acid, 20 parts of polyazelaic anhydride, 0.5 parts of maleic anhydride, 10 parts of tung oilic anhydride and 45 parts of methyltetrahydrophthalic anhydride to 300 parts of asphalt at 150°C (Asphalt place of origin: Koch, Ezhou, Hubei), stir evenly until the system viscosity is almost uniform, add 196 parts of tung oil modified epoxy resin, stir until the system viscosity is uniform, then add 200 parts of B part CYD-128 type epoxy resin, Mix evenly, make the epoxy asphalt material that expressway of the present invention and road bridge are used; Mix in stone material again, compact, heat preservation 5hr, prepare epoxy asphalt concrete, also can not mix in stone material, directly as pavement bonding layer material . The performance of the material itself and the performance of the prepared epoxy asphalt concrete are shown in Table 1 and Table 2.

Embodiment 2

[0024] Example 2: Add 15 parts of oxalic acid, 65 parts of succinic acid, 10 parts of tung oil anhydride and 40 parts of methyltetrahydrophthalic anhydride to 300 parts of asphalt at 140°C (place of asphalt origin: Keshi, Ezhou, Hubei), and stir evenly , until the system viscosity is almost uniform, add 250 parts of tung oil modified epoxy resin, stir until the system viscosity is uniform, then add 200 parts of E-44 type epoxy resin in part B, mix uniformly, and make the highway and road bridge of the present invention Epoxy asphalt material used; then mixed with stones, compacted, and kept warm for 5 hours to prepare epoxy asphalt concrete, or not mixed with stones, directly used as the road surface bonding layer material. The performance of the material itself and the performance of the prepared epoxy asphalt concrete are shown in Table 1 and Table 2.

Embodiment 3

[0025] Example 3: 10 parts of oxalic acid, 20 parts of adipic acid, 20 parts of tung oil anhydride, 50 parts of methyltetrahydrophthalic anhydride and 0.1 part of diethylenetriamine were added to 300 parts of asphalt at 140°C (place of asphalt origin: Ezhou, Hubei Coriolis), stir evenly until the system viscosity is almost uniform, add 150 parts of tung oil modified epoxy resin, stir until the system viscosity is uniform, then add 200 parts of CYD-014 type epoxy resin in part B, mix uniformly, and obtain this product Invented epoxy asphalt material for highways and road bridges; then mixed with stones, compacted, and kept warm for 5 hours to prepare epoxy asphalt concrete, or not mixed with stones, directly used as road surface bonding layer materials. The performance of the material itself and the performance of the prepared epoxy asphalt concrete are shown in Table 1 and Table 2.

Abstract

The invention relates to an epoxy bitumen material for a highway and a road bridge and a preparation method thereof. The epoxy bitumen material comprises a part A and a part B in mass ratio of 2.0-3.5:1, wherein the part A comprises the following components in parts by mass: 300 parts of bitumen, 90-250 parts of tung oil modified epoxy rein, 30-90 parts of dicarboxylic acid of aliphatic series or anhydride of dicarboxylic acid polyaliphatic series, 0-1 part of epoxy resin curing agent and 40-70 parts of unsaturated anhydride; and the part B comprises epoxy resin or/and epoxy-containing glycidyl ether. The preparation method comprises the step of: uniformly mixing materials of the part A except for the bitumen and the part B into the bitumen. The prepared epoxy bitumen material is cured, a system is in a homogeneous phase, and the cured product has the advantages of high strength, high extending ratio and ultra fatigue resistance property, simple process and short production period. The invention is used in occasions with higher strength of the highway, the road, and the like, and can be used for repairing an arterial street, a bus stop, an airport road surface, a road surface, and the like, such as pouring cracks.

Description

technical field [0001] The invention relates to a novel epoxy asphalt material for highways and road bridges and a preparation method thereof. Background technique [0002] The main component of petroleum asphalt is a mixture of aliphatic hydrocarbons and aromatic hydrocarbons, and its solubility parameter is about 8.66, while the solubility parameter of epoxy resin is 10.36, so it is difficult to be compatible. In order to effectively prepare epoxy asphalt raw materials, scientists have adopted the following processes: co-solvent method, modified asphalt method, special epoxy resin method and modified curing agent method. For example, in U.S.Pat.3,012,487, pine tar is used as a co-solvent for epoxy resin and asphalt, and diethylenetriamine, phthalic anhydride, etc. are used as curing agents to successfully prepare epoxy asphalt bonding materials and apply them to concrete surfaces. And in the roadbed, a hard, rough, solvent-resistant anti-skid coating is obtained. Obviousl...
