Embodiment 1
[0030] Example 1 An epoxy-modified light-colored emulsified asphalt, which is configured by the following parts by weight: 55 parts of decolorized asphalt, 48 parts of deionized water, 2 parts of cationic fast-setting and slow-cracking emulsifier, oxidized polyethylene 5 parts of wax, 0.168 parts of 2-hydroxy-4-n-octyloxybenzophenone, 0.21 parts of monoisooctyl phosphite, 21 parts of bisphenol A epoxy resin, and 18 parts of water-soluble polyamide.
[0031] The specific preparation steps are:
[0032] (1) Heat up the deionized water to 60°C, mix the oxidized polyethylene wax, the cationic fast-setting and slow-cracking emulsifier according to the above ratio, stir until uniform, and adjust the acid to PH=2. Add the above-mentioned decolorized asphalt and mix it into the emulsifying shearing machine, cutting at 5000r / min for 3~5min, for use;
[0033] (2) Pour the water-soluble polyamide, epoxy, benzenediisooctyl phosphite and 2-hydroxy-4-n-octyloxybenzophenone into the above-mentione...
Embodiment 2
[0039] Example 2 An epoxy-modified light-colored emulsified asphalt, which is configured by the following parts by weight: 52 parts of decolorized asphalt, 50 parts of deionized water, 1.8 parts of cationic fast-setting and slow-cracking emulsifier, oxidized polyethylene 4.5 parts of wax, 0.144 parts of 2-hydroxy-4-n-octyloxy benzophenone, and 0.12 parts of phenyl diisooctyl phosphite. 18 parts of bisphenol A epoxy resin, 17 parts of water-soluble polyamide;
[0040] Preparation process steps: prepared according to the preparation process steps of Example 1.
[0041] The modified light-colored emulsified asphalt prepared according to the above method will be verified in accordance with the corresponding experiments in the "Highway Engineering Asphalt Mixture Experimental Regulations", and the experimental results are shown in the following table:
[0042]
[0043] Therefore, using the modified light-colored emulsified asphalt of this embodiment can improve the abrasion and weather r...
Embodiment 3-6
[0044] Example 3-6: An epoxy-modified light-colored emulsified asphalt, composed of the following components in the following parts by weight:
[0045]
[0046]
[0047] Preparation process steps: prepared according to the preparation process steps of Example 1.
[0048] The modified light-colored emulsified asphalt prepared according to the above method will be verified in accordance with the corresponding experiments in the "Highway Engineering Asphalt Mixture Experimental Regulations". The experimental results are shown in the following table:
[0049]
[0050] In summary, using the modified light-colored emulsified asphalt of Examples 3-6 can improve the wear resistance and weather resistance of the asphalt, and has good adhesion performance and high yield. After dyeing, it can be used as colored asphalt, which can be used for heavy-duty roads and parking lots.
