Embodiment 1

[0013] The invention discloses a method for preparing a concrete foaming agent. The foaming agent, lauryl alcohol, rosin soap, gelatin, acrylic acid emulsion, cement sealant and water are used as raw materials to mix and stir evenly in a reactor.

[0014] Proportioning is carried out according to the following ratio, wherein foaming agent accounts for 12%, lauryl alcohol accounts for 1%, rosin soap liquid accounts for 13%, gelatin accounts for 2%, acrylic emulsion accounts for 5%, cement sealant accounts for Ratio of 2%, water accounts for 65%, when proportioning according to the above ratio, proceed as follows:

[0015] Step 1, add water to the reactor and heat to not lower than 95°;

[0016] Step 2, drop into gelatin, rosin soap liquid and stir evenly after being dissolved;

[0017] Step 3, after the temperature of the solution in the reaction kettle in the previous step is cooled to 45-50°, add air bubble agent, lauryl alcohol, acrylic emulsion, and cement sealant and stir...

Abstract

The invention discloses a concrete foaming agent preparation method. A foaming agent, laurinol, rosin soap solution, gelatin, acrylic acid emulsion, cement sealant and water are utilized as raw materials, the raw materials are evenly mixed and stirred in a reaction kettle, and the raw materials are matched according to the following matching that the proportion of the foaming agent is 12%, the proportion of the laurinol is 1%, the proportion of rosin soap solution is 13%, the proportion of the gelatin is 2%, the proportion of the acrylic acid emulsion is 5%, the proportion of the cement sealant is 2%, and the proportion of water is 65%. The preparation method comprises the steps of firstly adding water into the reaction kettle to be heated to be not lower than 95 DEG C; then adding the gelatin and the rosin soap solution and evenly stirring after dissolving; adding the foaming agent, the laurinol, the acrylic acid emulsion and the cement sealant to be fully stirred for 3 hours after temperature of solution in the reaction kettle in the last step is cooled to 45 to 50 DEG C, wherein stirring speed is controlled as 180 turns / minute. The foaming agent is an AES foaming agent or an AOS foaming agent. The foaming agent prepared through the preparation method has good stability, is suitable for varieties of cement, has small foam diameter, improves concrete strength and is safe and environmentally friendly.
