Problems solved by technology

[0003] There are many types of foam concrete foaming agents, mainly rosin foaming agents, protein foaming agents, synthetic foaming agents, etc. Among them, rosin foaming agents have the longest history and have the advantages of low price and convenient manufacture. The foam stability and foaming ratio are not very good; the foam produced by the protein foaming agent has good stability, but its foaming power is low, it is easy to mildew and the source of raw materials is greatly limited; the synthetic foaming agent The foaming ability is very good, and the source is also wide, but the stability of the generated foam is not good

preparation example Construction

[0022] Such as figure 1 Shown, the preparation method of a kind of foam concrete blowing agent of the present invention, comprises the steps:

[0023] Step 10. Prepare the ingredients according to the following volume ratio: 100% water; 6-10% saponin; 2-5% sodium dodecyl sulfonate; 1-4% polyethylene glycol; 0.02% benzoic acid ~3%; cellulose 0.8~3%;

[0024] Step 20, place water, saponin, sodium dodecyl sulfonate, polyethylene glycol, and cellulose in a hydrothermal synthesis reactor to react for 3 to 5 hours; the temperature of the hydrothermal synthesis reactor is limited to 60 ~80°C;

[0025] Step 30, after cooling the solution prepared by the reaction to room temperature, add benzoic acid, stir evenly, and then discharge.

Embodiment 1

[0027] Example 1: 100kg of water, 7kg of saponin, 3kg of sodium dodecyl sulfonate, 3kg of polyethylene glycol and 1.2kg of cellulose are placed in a hydrothermal synthesis reactor at (60-80) After reacting at ℃ for 4-5 hours, cooling the prepared solution to room temperature, adding 1 kg of benzoic acid, and stirring evenly, the foamed concrete foaming agent was prepared. According to the standard JG / T266-2011 "Foamed Concrete", the foaming agent was tested, and the test results were as follows: the foaming ratio was 67, the settlement distance was 4mm, and the bleeding volume was 28ml. The performance of the above foaming agent was tested The result is better than the technical requirements of the blowing agent in the standard.

Embodiment 2

[0028] Embodiment two: the water of 100kg, the saponin of 9kg, the sodium dodecyl sulfonate of 3kg, the polyethylene glycol of 3.6kg, the cellulose of 1.5kg are placed in the hydrothermal synthesis reactor at (60- 80) React at ℃ for 4-5 hours, cool the prepared solution to room temperature, then add 0.8 kg of benzoic acid, stir evenly, and prepare the foam concrete foaming agent. According to the standard JG / T266-2011 "Foamed Concrete", the foaming agent was tested, and the test results were as follows: the foaming ratio was 82, the settlement distance was 6mm, and the bleeding amount was 32ml. The performance of the above foaming agent was tested The result is better than the technical requirements of the blowing agent in the standard.

Abstract

The invention provides a foam concrete foaming agent which comprises the following raw materials in percentage by weight: 100% of water, 6%-10% of saponin, 2%-5% of sodium dodecyl sulfate, 1%-4% of polyethylene glycol, 0.02%-3% of benzoic acid and 0.8%-3% of cellulose. The invention further provides a preparation method of the foam concrete foaming agent. The surfactants, namely the sodium dodecyl sulfate and the polyethylene glycol are adopted, so that a foaming effect of the foaming agent is uniform and can be further improved; moreover, the benzoic acid is capable of effectively overcoming the shortcoming of easiness in mildewing of the foaming agent and prolonging the storage cycle of the foaming agent.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to a foam concrete foaming agent and a preparation method thereof. Background technique [0002] Foam concrete is a kind of porous concrete with a large number of closed pores inside, which is formed by introducing an appropriate amount of tiny air bubbles into the cement slurry, stirring evenly and then pouring and hardening. It has excellent properties such as light weight, heat preservation, and heat insulation. The performance of foam concrete is affected by many factors, among which the performance of foam concrete foaming agent has a great influence on it. [0003] There are many types of foam concrete foaming agents, mainly rosin foaming agents, protein foaming agents, synthetic foaming agents, etc. Among them, rosin foaming agents have the longest history and have the advantages of low price and convenient manufacture. The foam stability and foaming ratio are ...
