[0030] 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.
[0031] The integrated self-insulating lightweight wallboard is expressed by the ratio of each raw material and text in Table 1 (weight unit: kg)
[0032] Table 1
[0033]
[0034]
[0035] The preparation method of described whipping agent is as follows:
[0036] A. Part B: 10-25 parts of calcium chloride, 12-15 parts of sodium nitrite, 8-10 parts of sodium sulfate, 0.2-0.5 parts of triethanolamine, 54.7-64.5 parts of water; heat the water to 30-50°C Finally, add the above components at the same time, stir evenly and pack into barrels for later use;
[0037] B. Component A: Take 53.5-55.8 parts of water, heat 30% of the water at 70-80°C and dilute the polyvinyl alcohol for use; put the remaining water into a heat container,...
