Example Embodiment
[0018] The present invention will be further described in conjunction with the following examples. It should be understood that these examples are only for illustrative purposes and in no way limit the protection scope of the present invention.
[0019] The implementation mode of the composite foaming agent is described by the ratio of each raw material and the text in Table 1, and its weight unit is calculated by heart:
[0020] Table 1
[0021]
[0022]
[0023] Taking Example 2 as an example, the method for preparing the composite concrete foaming agent of the present invention is as follows:
[0024] Weigh the raw materials according to Table 1, take 54.65kg of water, heat it with 30% of the water to 70-80°C and dilute the polyvinyl alcohol for use; put the remaining water in a heated container, and process 4kg of industrial caustic soda; Add 20kg of rosin, pyrolyze at 70-80℃ while stirring. After the raw materials are fully dissolved, cool to room temperature for about 100 minute...
