Abstract

The invention discloses a porous environment-friendly material. The specific gravity of the porous environment-friendly material is 0.6-1.1, and the hydroscopicity is below 15%; the porous environment-friendly material is prepared by the following steps: glass powder as well as sludge sand and sediment which are produced by dehydration, desiccation and burning from a sewage treatment plant are mixed according to a proportion of 35-80:1-10 in parts by weight, grinding is carried out, and a primary powder mixture is obtained; the primary powder mixture is screened and treated, and the screened primary powder mixture composed of glass powder as well as sludge sand and sediment is added into a mixing and stirring device; 5-20 parts of clam shells and 1-15 parts of vermiculite powder are added into the mixing and stirring device in the step 4, mixing and stirring are carried out for the clam shells, the vermiculite powder, the glass powder, and the sludge sand and sediment, and mixed power is formed; the mixed power is added into a sintering furnace, and the porous environment-friendly material is manufactured at a high temperature condition. Recycle of waste glass and regeneration of sludge sand and sediment are organically combined with breakthrough, bubbles are enclosed, independent and discontinuous, and the environment-friendly material can be used as building light-weight frame material, construction foundation material, and water quality purifying material.

Description

technical field [0001] The invention relates to environment-friendly materials, in particular to a porous environment-friendly material. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, glass is not only widely used in housing construction and people's daily life, but also developed into an indispensable new material for scientific research, production and cutting-edge technology. At the same time, it is inevitable to produce a lot of glass waste and form a large amount of waste glass. Take a glass factory as an example. Under normal production conditions, the corner glass cut from the original plate glass accounts for about 15%-25% of the total glass production, and a considerable part of waste glass is waste glass produced by regular shutdowns. It accounts for about 5%-10% of the total glass production. Occasional fluctuations in the operating temperature of the melting furnace, sudden ch...
