Abstract

The invention relates to a multifunctional environment-friendly foam glass product and a preparation method thereof, in particular relates to an environment-friendly foam glass product which is applied to a wall body of a building, a freezing device and the like for heat insulating and sound absorbing, and a preparation method of the environment-friendly foam glass product, and belongs to the technical field of glass products. The preparation method comprises the following steps: getting waste glass and an inorganic nonmetal solid mixture as the main raw materials; adding a complex solubilizer, a foaming agent, a foam stabilizing agent and an accelerator; breaking; mixing and performing ball milling in a dry manner; adding an inorganic fiber material; transferring the mixture into a die; sintering and modeling; then cooling to obtain the foam glass product. The preparation method is simple in process operation, energy-saving, environment-friendly and outstanding in product performance; the density of the foam glass product is 100 to 600kg / m<3>, and the compressive strength is 4 to 15MPa; the multifunctional environment-friendly foam glass product has the characteristics of being light in weight, absorbing sound, being high in mechanical strength, small in thermal conductivity, stable in thermal performance, flame retardant, anticorrosive and waterproof, and the like.

Description

(1) Technical field [0001] The invention relates to a multifunctional environmentally friendly foamed glass product and a preparation method thereof, in particular to an environmentally friendly foamed glass product used for building walls, refrigeration devices, etc., having the functions of heat insulation and sound absorption, and a preparation method thereof. (2) Background technology [0002] In recent years, with the continuous enhancement of people's environmental awareness and the shortage of natural resources, the recycling of industrial waste such as waste glass has received increasing attention. Foam glass is a porous material made from waste glass and filled with numerous small bubbles. Its properties are different from ordinary glass. It has the advantages of high strength, low density, low thermal conductivity, long service life, easy processing and sawing. This kind of energy-saving and environmentally-friendly material with good thermal insulation and sound absorp...
