Embodiment 1
[0018] A method for making an environmentally friendly thermal insulation wall, comprising the following steps:
[0019] (1) Cut the galvanized sheet according to the design size and punch the angle to obtain the corresponding shape of the sheet, and then press the sheet into the corresponding shape through the punching machine, wherein the upper or lower top surface connected to the wall sheet and the wall surface The board forms a right-angle structure, and the side connected to the wall is a board or a plane board with matching concave buckles 5 and convex buckles 4;
[0020] (2) Combine the obtained plates to obtain a sealed hollow wall block, and fill the hollow wall block with insulation cotton;
[0021] Wherein, the preparation method of the thermal insulation cotton is as follows: put pineapple leaves and mulberry bark in a sodium hydroxide solution with a mass concentration of 5%, soak for 6 hours under vacuum conditions, and mechanically decompose for 25 minutes and ...
Embodiment 2
[0028] A method for making an environmentally friendly thermal insulation wall surface, wherein the thermal insulation cotton is prepared by putting pineapple leaves and mulberry bark in a sodium hydroxide solution with a mass concentration of 5%, soaking them under vacuum for 8 hours, and mechanically dissolving them for 25 minutes. Refining after 10 minutes to obtain the slurry, the irradiated slurry was irradiated for 35 minutes under the condition that the irradiation dose was 600KGy; Sodium polyacrylate, 0.5% boric acid, 0.3% trifluoromethylaniline, 0.5% polyvinylpyrrolidone, 3.5% 4,4-disulfonylhydrazide diphenyl ether, stirring reaction to obtain a foam, the foam The foam is poured into the mold, filtered, dried and shaped; wherein, the temperature of the process of preparing the foam is 170°C, and the reaction time is 1 hour; the drying temperature of the foam is 90°C, and the dry shape The time is 12 hours.
