3D printing self heat insulation wall body and preparing method of 3D printing self heat insulation wall body
The invention relates to a 3D (3-Dimentional) printing self heat insulation wall body and a preparing method of the 3D printing self heat insulation wall body, and aims at providing the 3D printing self heat insulation wall body with the advantages of high compressive strength, low heat conduction coefficient, low production cost and good heat insulation effect. The 3D printing self heat insulation wall body is prepared from 40 percent to 50 percent of cement, 30 percent to 40 percent of hollow microspheres, 10 percent to 20 percent of grading micro powder, 10 percent to 20 percent of quick setting modified emulsion according to the following step that prepared slurry is conveyed to wall body 3D printing equipment through conveying equipment to be printed and formed. The 3D printing self heat insulation wall body provided by the invention is at the B05 grade; the density is 500 to 525kg/m<3>; the compressive strength is higher than or equal to 3.5MPa; the heat conduction coefficient is lower than or equal to 0.011 W/(m*k); the building load can be reduced; the consumption of reinforced concrete is reduced; the building cost is reduced by more than 5 percent; the wall body internal and external heat insulation is not needed for the 3D printing self heat insulation wall body, and the requirement of 50 percent or 65 percent of the building energy saving can be met; and huge social benefits and economic benefits can be generated.
