Abstract

The invention relates to an environment-friendly soft porcelain preparation method which comprises the steps of preparing nano silver fiber, modifying boron nitride nanotubes, preparing phase change microcapsules, preparing soft porcelain and performing surface treatment. The environment-friendly soft porcelain is prepared from 30 to 50 parts of inorganic powder, 15 to 35 parts of cement, 10 to 15parts of phase change microcapsules, 10 to 30 parts of acrylic polymer emulsion, 0 to 2 parts of pigment, 0.5 to 2 parts of a coupling agent, 0.5 to 1.2 parts of montmorillonite, 0.5 to 1.2 parts ofkieselguhr and 0.8 to 1.5 parts of wood fiber. The environment-friendly soft porcelain prepared by the preparation method disclosed by the invention has the advantages of good breathability and antifouling, self-cleaning, temperature-regulating and moisture-control performance.

Description

technical field [0001] The invention relates to the field of construction and decoration materials, in particular to a preparation method of environment-friendly soft porcelain. Background technique [0002] Modified inorganic powder material, referred to as MCM decoration material, commonly known as soft porcelain, is made of natural primitive soil, urban construction waste soil, cement waste, porcelain slag, stone powder and other inorganic substances as raw materials. Formed under heterogeneous and curved temperatures, the wall veneer panels made have good appearance and texture, and are characterized by softness, thinness, lightness, safety, and convenient construction. Soft porcelain technology is in line with the development trend of environmental protection and energy saving in terms of energy saving and emission reduction indicators. It is a new type of low-carbon environmental protection decorative material for reuse of construction waste, and has extensive promotio...
