Abstract

The invention discloses regenerated lightweight silicon spar and a preparation method thereof. The regenerated lightweight silicon spar is prepared from the materials of, by weight: 5-99.5 parts of waste glass, 3-90 parts of sand, 0.01-10 parts of a foaming agent, and 0.01-10 parts of a flux. Through steps of grinding, mixing and granulation, foaming agent and flux adding, high-temperature heating, melting, sintering, foaming, and annealing, the regenerated lightweight silicon spar is obtained. With the method provided by the invention, a problem of recycling difficulty of large amount of waste glass is solved, and waste is turned into valuable matters; waste glass processing process is simplified, washing is not needed, impurities such as labels are not needed to be removed, sorting according to color and type is not needed, and various types of waste glass can be mixed and processed together without washing and sorting; the produced regenerated lightweight silicon spar is a novel inorganic heat insulation material with an environment-protection function, and can be widely applied in the fields such as rainwater storage and utilization, barren hill, wasteland, and urban landscape greening, heat-insulation construction material, and the like.

Description

technical field [0001] The invention relates to a regenerated light silica crystal and a preparation method thereof, belonging to the technical field of waste glass treatment. Background technique [0002] Glass is an important item with huge consumption in people's daily life, but at present, the recycling rate of waste glass in China is low. According to a data from the Ministry of Commerce, the recycling rate of waste glass in my country is less than 13%. Effectively recycled, most of these waste glass become pollutants flooding urban garbage dumps, which not only damages the environment but also wastes resources. [0003] In the existing waste glass processing technology, there are the following technical defects: [0004] 1. A small part of waste glass that can be recycled can be sorted and cleaned, and some can be directly reused after being selected, and remade into glass products after returning to the furnace. However, most of the recycling factories are glass manuf...
