example 1

[0034] (1), fineness is 80 μ m waste glass particles 92Kg, fineness is 20 μ m marble powder 4Kg and fineness is 20 μ m quicklime 4Kg and mixes and makes foaming mixture;

[0035] (2), the sintered foaming mixture that above-mentioned making is piled up in heating furnace, and stacking thickness is 25cm, and heating furnace is muffle furnace; Foaming mixture is through preheating in heating furnace, heating up for the first time, firing After heating, second heating and foaming heating, the sintered and foamed heating material is obtained, and the sintered and foamed heating material is taken out from the heating furnace, and then naturally cooled to room temperature to obtain the finished microporous foamed glass pumice; microporous The diameter is 1.0-1.2mm; the preheating temperature is 390°C and the preheating time is 10 minutes; the heating temperature for the first heating is 690°C and the heating time is 15 minutes; the firing heating temperature is 750°C and the heating ...

example 2

[0038] (1) Mix 91Kg of waste glass particles with a fineness of 60 μm, 3Kg of marble powder with a fineness of 30 μm, 4Kg of quicklime with a fineness of 30 μm, 1Kg of gypsum powder with a fineness of 40 μm and 1Kg of feldspar with a fineness of 40 μm A foaming mixture is prepared;

[0039] (2), the above-mentioned prepared foaming mixture is stacked in a heating furnace, the stacking thickness is 20cm, and the heating furnace is a muffle furnace; the foaming mixture is preheated in the heating furnace, heated for the first time, and fired for heating 1. After the second heating and foaming heating, the sintered and foamed heating material is obtained. The sintered and foamed heating material is taken out from the heating furnace and then naturally cooled to room temperature to obtain the finished microporous foamed glass pumice. The diameter of the micropores is 1.3~1.5mm; the preheating temperature is 395°C, and the preheating time is 8 minutes; the heating temperature for t...

Abstract

The invention relates to a micro-pore foaming glass pumice stone, which is characterized by being prepared by carrying out high-temperature heating and foaming, and cooling on a foaming mixture of components according to weight percentage of 85-95 of waste glass grains, 1-10 of marble powder and 1-10 of quick lime. The diameter of a micro-pore of the micro-pore foaming glass pumice stone is 0.23-5mm. The invention further relates to a preparation method of the micro-pore foaming glass pumice stone. The micro-pore foaming glass pumice stone is obtained by regenerating and utilizing waste glass and is a novel material; and the micro-pore foaming glass pumice stone has the advantages of no pollution, light weight, water permeability, water-retaining property, ventilation, fire resistance (non-combustibility and fireproof property), heat insulation property and long-period effectiveness.

Description

technical field [0001] The invention relates to a microporous foamed glass pumice, in particular to a microporous foamed glass pumice and a preparation method thereof, which belongs to the recycling technology of waste glass resources. technical background [0002] Resource regeneration is an inevitable choice for the sustainable development of social economy. Resource regeneration is the need of environmental protection. In the 21st century, environmental protection has become the theme of world development. At present, glass is an important item with huge consumption in people's daily life. However, these The waste glass that has been consumed and used has not been effectively recycled and utilized, and most of it has become pollutants flooding urban garbage dumps, which not only damages the environment but also wastes resources. Waste glass can be divided into daily waste glass (ware glass, light bulb glass, etc.) and industrial waste glass (plate glass, glass fiber, etc....
