[0020] The embodiments of the present invention all consist of the following steps:
[0021] a. Weigh the fibers, toughening materials and surfactants listed in the table below and dissolve them in water to form a polymer emulsion;
[0022] b. Separately weigh the inorganic cementing materials, lightweight aggregates and fibers listed in the following table, put them in a mixer and mix them evenly to obtain a dry powder mixture;
[0023] c. Add the dry powder mixture of step b to the polymer emulsion of step a, stir and disperse to obtain a slurry;
[0024] d. Add the air-entraining agent listed in the following table to the slurry of step c, stir and disperse evenly, pour it into the film cavity, dry it completely, and then cut it.
[0025] The thermal conductivity test results of the plates prepared by each implementation are shown in the last column of the table. The test result shows that the heat preservation effect of the board of the invention is good...
