Abstract

The invention relates to a method for preparing a light porous inorganic gelled material product from gel particles. The method comprises the following steps of: preparing pore former particles of which the particle sizes are between 0.5 and 5 millimeters from a natural linear polysaccharide polymer and a gelled cross-linking agent; and doping the pore former particles separately or together withexpanded perlite particles and polystyrene foam particles into an inorganic gel material in a compounding mode according to different proportions so as to obtain the light porous material product. The volume density, intensity, pore size and density distribution of the material can be conveniently adjusted by altering the particle size and mixing amount of the pore former particles. The heat conductivity coefficient of the prepared light porous material is only between 0.12 and 0.17 w / m.k and high heat preserving performance and high heat insulating performance are achieved. The material can be used for molding and manufacturing materials having requirements on light weight, heat preservation, heat insulation, sound insulation, energy conservation and the like. The preparation method has the advantages of simpleness, safety, low energy consumption and easy control and adjustment.

Description

technical field

[0001] The invention relates to a method for preparing light-weight porous inorganic gelling material products with gel particles, which is used for making porous light-weight materials with thermal insulation and sound insulation properties. Background technique

[0002] At present, my country's economy is developing rapidly. Under the premise of sustainable development strategy, all walks of life have put forward the requirements of energy saving and consumption reduction. As a new type of building material and thermal insulation material, lightweight porous material has excellent properties such as light weight, thermal insulation, sound insulation, anti-aging, and good fire resistance, and meets the increasingly emphasized green, environmental protection, and energy-saving requirements in recent years. At present, in addition to light aggregates, most lightweight and porous materials also use foaming aids for foaming during molding. Since the sample has ...
