Embodiment Construction
[0018] The present invention will be further described below in conjunction with the examples. It should be understood that these examples are only for the purpose of illustration, and in no way limit the protection scope of the present invention.
[0019] Composite blowing agent implementation mode is expressed by the ratio of each raw material and text in Table 1, and its weight unit is calculated by heart:
[0020] Table 1
[0021]
[0022]
[0023] Take embodiment 2 as example to illustrate that the preparation method of composite concrete foaming agent of the present invention is as follows:
[0024] Take each raw material by weighing in table 1, get water 54.65kg, with wherein 30% water is heated to 70-80 ℃ after polyvinyl alcohol is diluted stand-by; Remaining water is put into heat container, processing industry caustic soda 4kg; Add 20kg of rosin, stir and pyrolyze at a temperature of 70-80°C, wait for about 100 minutes for the raw materials to fully dissolve a...
