| titleOfInvention | The preparation method of concrete additive |
| abstract | The invention discloses the preparation method of concrete additive, include by weight：1,200 1300 parts of sodium sulfanilate, 750 850 parts of phenol, 20 30 parts of acetone, 350 450 parts of liquid caustic soda, 80 100 parts of formaldehyde, 40 50 parts of urea, 10 15 parts of acrylamide.The present invention carries out condensation reaction using sulfanilate, phenol and formaldehyde; under the protection of acetone; phenol can be condensed as bis-phenol; acetone can be catalyzed the reaction of sulfanilate, phenol and formaldehyde three simultaneously; increase the molecular weight of condensation product; change dispersive property, improve the hardened situation of bleeding. |
