Abstract
The invention relates to a foaming micropore glass pumice for the heat preservation and insulation of a wall body. The foaming micropore glass pumice is characterized by comprising foaming micropores, wherein the aperture of the foaming micropore is 0.5-1 mm, the water absorption of the foaming micropore is 7%-12%, the strength is 9-12 MPa, the density is 0.5-0.6 g / cm<3>; the foaming micropore glass pumice is prepared by sintering a foaming mixture; and the foaming mixture comprises the following components in percentage by weight: 85%-90% of glass powder, 3%-8% of marble powder and 3%-8% of diatomite powder, wherein the fineness of the glass powder is 40-100 micrometers, the fineness of the marble powder is 20-40 micrometers, and the fineness of the diatomite powder is 20-40 micrometers. The invention also relates to a preparation method of the foaming micropore glass pumice for the heat preservation and insulation of the wall body. The foaming micropore glass pumice disclosed by the invention has the advantages of good heat preservation and low usage cost without generating pollution on the environment in producing and using processes.
