[0017] Example 1
[0018] (1) Negative slow-setting paint
[0019] The raw materials (parts by weight) of the negative retarding coating 1 are as follows: 120# solvent oil 100 parts, rosin 40 parts, rosin glyceride 20 parts, humic acid 2.4 parts, sodium acetate 1.2 parts, wollastonite powder 80 parts, talc powder 20 parts, 50 parts calcined kaolin, 0.8 parts iron oxide pigment, 1.5 parts EFKA 4010, 5 parts white carbon black, 10 parts organic bentonite.
[0020] The preparation method of negative retarding coating 1 includes the following steps: heating the solvent to 60-90°C, adding an adhesive under stirring to dissolve it; then adding wetting and dispersing agent, retarder, pigment and filler, and stirring evenly ; Finally, the thickener is added and stirred evenly to obtain the concrete negative retarding coating.
[0021] (2) Control paint
[0022] The raw materials (parts by weight) of the control paint 1 are as follows: 100 parts of 120# solvent naphtha, 40 parts of rosin, 20 p...

[0031] Example 2
[0032] The raw materials (parts by weight) of the concrete negative retarding coating 2 are as follows: 60 parts of 200# solvent naphtha, 60 parts of rosin, 4.5 parts of humic acid, 1.5 parts of sodium acetate, 150 parts of wollastonite powder, 50 parts of calcined kaolin, oxidation 1.2 parts of iron pigment, 2.2 parts of EFKA 4010, 8 parts of white carbon black. The preparation method is the same as in Example 1.
Example Embodiment
[0033] Example 3
[0034] The raw materials (parts by weight) of the concrete negative retarding coating 3 are as follows: 120# solvent oil 100 parts, naphthenic oil 50 parts, rosin glyceride 50 parts, humic acid 4 parts, sodium acetate 2 parts, calcined kaolin 100 parts, 50 parts of wollastonite powder, 1.2 parts of iron oxide pigment, 1.2 parts of SN5040, 20 parts of organic bentonite. The preparation method is the same as in Example 1.
[0035] Spray the negative retarding coatings 2 and 3 uniformly on different mold surfaces by spraying. After the coating is dry, pour C30 self-compacting decorative concrete on the surface. After 24 hours, the concrete is demoulded and rinsed with a high-pressure water gun. Surface, to investigate the negative retarding effect of each coating. C30 self-compacting decorative concrete formula (parts by weight): 264 parts of PW42.5 cement, 87 parts of S95 slag powder, 902 parts of sand, 956 parts of stones, 152 parts of water, and 6.6 parts of wa...
