Abstract

The invention relates to a water-soluble high-efficiency concrete rosin air entraining agent and a preparation method thereof. The rosin air retraining agent is prepared from 50-70 parts of rosin resin, 0.5-1.0 part of p-methyl benzenesulfonic acid, 10-20 parts of unsaturated diacids, 20-40 parts of alkylphenol polyoxyethylene, 3-5 parts of triethanolamine and 160-250 parts of deionized water. The invention also provides the preparation method of the rosin air entraining agent. The air entraining agent has the advantages of good water solubility, good air entraining, bubble stabilizing and dispersing performances, convenience in construction, and good economic and practical property. A test result shows that the air entraining agent has good low-temperature dissolving performance, additive compatibility, air entraining performance and bubble stabilizing performance, and good concrete construction workability, is suitable for being used in roads, bridges, reservoirs, dikes, buildings and other concrete engineering, and is especially suitable for being used in concrete structures with high antifreeze durability requirements, such as water conservancy projects, maritime works, roads and bridges and other national large engineering, and road and bridge engineering in the north and other alpine regions.

Description

technical field [0001] The invention relates to a concrete air-entraining agent, in particular to a water-soluble high-efficiency concrete rosin air-entraining agent. The invention also relates to a preparation method of the water-soluble high-efficiency concrete rosin air-entraining agent. Background technique [0002] Concrete air-entraining agents commonly used in the market mainly include sulfonic acid air-entraining agents and rosin soap air-entraining agents. Among them, the air-entraining agent produced by alkylsulfonate air-entraining agent has a large volume and poor stability of the bubbles, which affects the apparent quality of the concrete after hardening. Rosin soap air-entraining agent has good air-entraining ability and good bubble stability. However, the solubility of rosin soap in aqueous solution is small, and its dilute solution is in the form of emulsion, which must be shaken before use; when used in winter, due to the drop in temperature, the solubilit...
