Description

technical field [0001] The application belongs to the field of decorative materials, and in particular relates to a method for preparing a heat-preserving, water-, alkali-, and low-temperature-resistance material for buildings. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Every ton of mineral wool insulation products used in buildings can save one ton of oil a year. [0003] R&D background: Traditional thermal insulation materials are mainly to increase the gas phase porosity and reduce the thermal conductivity and conductivity. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicke...
