Embodiment 1
[0035]A method for preparing a highly adaptable mud-resistant water reducer, which is formed by polymerizing the following components, the total mass of raw materials is 1000 parts, and each raw material component includes:
[0036] 16.8 parts of 2-(allyloxy)phenol
[0037] Ethylene oxide 61.0 parts
[0038] Propylene oxide 242.1 parts
[0039] 0.8 parts of boron trifluoride and lithium aluminum tetrahydride with a mass ratio of 1:2.3
[0040] Acrylic acid 33.0 parts
[0041] 5.6 parts of ascorbic acid and sodium formaldehyde sulfoxylate with a mass ratio of 1:1.2
[0042] The mass ratio is 2:1 ammonium persulfate and azobisisobutyronitrile 6.7 parts
[0043] 3.2 parts of thioglycolic acid and mercaptoethanol with a mass ratio of 2:1.3
[0044] 7.3 parts of sodium bicarbonate and triisopropanolamine with a mass ratio of 1.3:1
[0045] The remainder is water, and the total mass is 1000 parts.
[0046] The preparation method is as follows:
[0047] (1) Add 16.80 parts of...
Embodiment 2-6
[0051] Concrete parameter (step is identical) in concrete raw material and preparation method is different with embodiment 1, specifically as shown in following table 1 and table 2 (table 1 is raw material, and table 2 is the parameter in preparation method), in table 2 Not listed expression is identical with embodiment 1:
[0052] The parts are all parts by mass.
[0053] Table 1

[0055]
[0056]
[0057] Table 2
[0058]
[0059] The product of the present invention and Hubei Tengchen TC-900J water reducing agent were prepared into C50 concrete samples, and Tables 3 and 4 were obtained through testing.
[0060] table 3
[0061]
[0062] Table 4
[0063]
[0064] It can be seen from Table 4 that the highly adaptable anti-mud type superplasticizer solution synthesized by the method of the present invention shows better slump, water reducing rate and bleeding rate in the concrete system.
