| titleOfInvention | Modified air entraining agent and preparation method thereof |
| abstract | The invention relates to the technical field of air entraining agents, in particular to a modified air entraining agent and a preparation method thereof, wherein the modified air entraining agent comprises the following components in parts by weight: 50-60 parts of allyl fatty alcohol-polyoxyethylene ether, 5-9 parts of sodium laureth sulfate, 15-20 parts of sulfamic acid, 0.6-1 part of urea peroxide, 1-4 parts of an antifreezing component, 0.2-0.6 part of catechol, 0.7-1.3 parts of hydroxypropyl methyl fiber, 0.1-0.4 part of starch ether and 66-70 parts of water; the air entraining agent effectively solves the problem of poor adaptability with polycarboxylic acid water reducing agents and cement, has the advantages of simple process, quick reaction, good bubble and bubble stabilizing effect and good bubble compactness and bubble stabilizing time, can introduce fine and uniform stable bubbles into concrete, effectively improves the strength and frost resistance of the concrete when used in combination with the water reducing agents, and reduces the slump loss of the concrete. |
