example 1

[0021] Example 1: 100 parts of double-part A-type epoxy resin (diphenol-based propane glycidyl ether) was added to an aqueous solution of 100 parts of nonionic surfactant alkylphenol polyethylene oxide with a content of 5%. Stir the mixer until it is uniformly dispersed, without separation phenomenon, and without coarse particle agglomerates, and then the epoxy resin water emulsion is prepared.

example 2

[0022] Example 2. Mix 100 parts of an aqueous solution of 8% nonionic surfactant alkylphenol polyethylene oxide with 80 parts of nonylphenol-terminated polyurethane resin, and fully stir until it is uniformly dispersed, without separation, No coarse particle agglomerates can be made into water emulsified epoxy resin toughening agent.

example 3

[0023] Example 3. Aromatic amine, polyetheramine, alicyclic amine (60 parts) and an aqueous solution (40 parts) containing 5% to 10% of alkylphenol polyethylene oxide were mixed with a conventional mixer until they were completely compatible and dispersed. The epoxy resin curing agent can be made into small particles that can be seen without agglomeration.

[0024] Example 4. Mix the epoxy resin water emulsion with a mixing ratio of 80% with a water-emulsified epoxy resin toughener with a mixing ratio of 20%, and stir evenly to obtain an emulsified flexible epoxy resin.

[0025] Example 5. Emulsify 100 parts of flexible epoxy resin modified emulsified asphalt with a solid content of 60% and mix it with 6.5 parts of epoxy resin curing agent before use. After the two-component crosslinking and curing, it becomes insoluble and insoluble. The adhesive layer or coating polymer, the polymer, the epoxy resin content is 20%.

[0026] In the above-mentioned preparation and reaction pr...

Abstract

The invention relates to the technical field of engineering construction, in particular to thermosetting emulsified flexible epoxy resin modified emulsified asphalt. The emulsified asphalt is characterized in that alkylphenol polyoxyethylene is used for emulsifying two-component A epoxy resins to prepare epoxy resin water emulsion; the alkylphenol polyoxyethylene is used for emulsifying nonyl phenol-terminated polyurethane resins to prepare the water-emulsified epoxy resin toughening agent; the epoxy resin water emulsion is mixed with the water-emulsified epoxy resin toughening agent to prepare the emulsified flexible epoxy resin; mixture of one or more of modified aliphatic amine, phenolic aldehyde amine and the like and the alkylphenol polyoxyethylene are used for preparing the water-emulsified epoxy resin curing agent; and the emulsified flexible epoxy resin and the water-emulsified epoxy resin curing agent are mixed with emulsified asphalt. The emulsified asphalt has the advantages of convenient construction, conventional construction process and simple tools under normal temperature. The water-emulsified epoxy resin curing agent carries out reactive crosslinking with the emulsified flexible epoxy resin modified asphalt, so the performance of the emulsified asphalt is thoroughly changed, that is, the common emulsified asphalt begins melting at 60 DEG C and is hardened and undergoes frost crack at minus 20 DEG C, but the emulsified asphalt of the invention is not molten at 160 DEG C and is free from brittle rupture at minus 25 DEG C and maintains flexibility for a long time under normal temperature.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a thermosetting emulsified flexible epoxy resin which can be widely used in the waterproofing, bonding, grouting of highways, bridges and building foundations, as well as the stress absorbing layer of asphalt concrete pouring composite layers, etc. Modified emulsified asphalt. Background technique [0002] Since human civilization began to exist, the road has extended infinitely under people's feet. From the bumpy trails that people stepped on, to the cobblestone pavement, from the concrete poured concrete pavement to the asphalt pavement that is widely used today, it proves the development history of human civilization from one aspect. [0003] We know that the widely used asphalt pavement has the advantages of good wear resistance, no dust, and good braking performance of motor vehicles. However, it also has the disadvantages of low melting point and poor low...
