Embodiment 1
[0023] The cement foaming agent described in the present embodiment comprises the raw materials of following weight components: 1 part of rosin, 0.5 part of bone glue, 0.2 part of sodium hydroxide, 0.2 part of sodium lauryl sulfate, 3 parts of glutinous rice starch and 95 parts of water .
[0024] The rosin is first-grade rosin, and the bone glue is high-quality bone glue.
[0025] The cement foaming agent also includes 0.5 parts of silicone resin polyether emulsion as a foam stabilizer.
[0026] The mechanism of action of the silicone resin polyether emulsion is to change the internal order of the molecules so that the surfactant bubbles are arranged tightly and neatly, thereby forming a dense inner film, which makes the pressure resistance particularly strong and can control the bubble liquid. The structural stability of the film enables the orderly distribution of surfactant molecules in the liquid film of the bubbles, endows the foam with good elasticity and self-healing ...
Embodiment 2
[0039] This embodiment is the same as in Example 1, except that the raw materials of the weight components of the cement blowing agent are respectively: 1.5 parts of rosin, 0.8 part of bone glue, 0.3 part of sodium hydroxide, sodium lauryl sulfate 0.4 part, 4 parts of glutinous rice starch and 92.2 parts of water, described cement foaming agent also comprises 0.8 part of silicone resin polyether emulsions as foam stabilizer, and the preparation method of above-mentioned cement foaming agent comprises the steps:
[0040] (1) Weigh an appropriate amount of water, add rosin and sodium hydroxide when heated to 95°C, and keep stirring;
[0041] (2) After stirring for 18 minutes, add bone glue and continue stirring;
[0042] (3) After stirring for 13 minutes, add an appropriate amount of water and soaked glutinous rice starch, and stir for 8 minutes;
[0043] (4) Add silicone resin polyether emulsion, and continue to stir for 8 minutes;
[0044] (5) Add sodium lauryl sulfate at la...
Embodiment 3
[0046] This embodiment is the same as in Example 1, except that the raw materials of the weight components of the cement foaming agent are respectively: 1.9 parts of rosin, 1 part of bone glue, 0.5 part of sodium hydroxide, sodium lauryl sulfate 0.5 part, 5 parts of glutinous rice starch and 90 parts of water, described cement foaming agent also includes 1 part of silicone resin polyether emulsion as foam stabilizer, the preparation method of above-mentioned cement foaming agent comprises the steps:
[0047] (1) Weigh an appropriate amount of water, add rosin and sodium hydroxide when heated to 100°C, and keep stirring;
[0048] (2) After stirring for 15 minutes, add bone glue and continue stirring;
[0049] (3) After stirring for 10 minutes, add an appropriate amount of water and soaked glutinous rice starch, and stir for 5 minutes;
[0050] (4) Add silicone resin polyether emulsion, and continue to stir for 5 minutes;
[0051] (5) Add sodium lauryl sulfate at last, promptl...
