Embodiment 1

[0027] (1) Wash and dry the collected waste glass, crush and grind it, then sieve and classify it, and select 8-20 mesh glass particles;

[0028] (2) Weigh 100g of the 8-20 mesh glass particles in step (1) and put them into a cube iron mold, and pile them up naturally;

[0029] (3) Put the mold equipped with glass particles in step (2) into a firing furnace for firing at 720° C. for 120 minutes, and cool naturally to room temperature to obtain a cube-shaped water-permeable filter material.

Embodiment 2

[0031] (1) Wash and dry the collected waste glass, crush and grind it, then sieve and classify it, and select 20-40 mesh glass particles;

[0032] (2) Weigh 100g of 20-40 mesh glass particles in step (1) and put them into a cube iron mold, and pile them up naturally;

[0033] (3) Put the mold equipped with glass particles in the step (2) into a firing furnace for firing at 720° C. for 80 minutes, and cool naturally to room temperature to obtain a cube-shaped water-permeable filter material.

Embodiment 3

[0035] (1) Wash and dry the collected waste glass, crush and grind it, then sieve and classify it, and select 40-80 mesh glass particles;

[0036] (2) Weigh 100g of 40-80 mesh glass particles in step (1) and put them into a cube iron mold, and pile them up naturally;

[0037] (3) Put the mold equipped with glass particles in step (2) into a firing furnace for firing at 720° C. for 40 minutes, and cool naturally to room temperature to obtain a cube-shaped water-permeable filter material.

Abstract

Disclosed are a water permeable material and a preparation method thereof. Waste glass is crushed and sieved for classification, and four classes of glass granules separately with particle sizes of 8 mesh or more, 8-20 mesh, 20-40 mesh and 40-80 mesh are obtained; any class of the glass granules in the four classes of glass granules is placed into a forming mould and is piled together; and sintering and cooling are performed to obtain the water permeable filter material. The method provided by the invention selects one class of glass granules with similar grain sizes for accumulation by using a character that a large porosity can be formed by close accumulation of equal-diameter balls, achieves self adhesion of the glass granules and further enables forming of a stable skeleton structure by using glass cohesive action caused by self softening of the glass granules in a temperature of the softening temperature or above, and organically combines solid waste utilization with reduction of environment loads by using the waste glass as a raw material so as to enable recycling of resources and effectively save the resources. The prepared product has double functions of water permeation and filtering. The method provided by the invention also has the advantages of simple technology, low energy consumption and low cost.

Description

technical field [0001] The invention belongs to the technical field of ecological materials, and in particular relates to a water-permeable material and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living standards, glass is widely used in house construction and people's daily life. At the same time, it is inevitable to produce a lot of glass waste, forming a large amount of waste glass. According to the statistics of some developed countries in Europe and the United States, the amount of waste glass accounts for 4% to 8% of the total urban waste. my country produces more than 10 million tons of waste glass every year, accounting for 5% of the total solid waste. China's waste glass recycling rate is only about 13%, and a large amount of waste glass has not been effectively recycled and utilized. The general treatment is to incinerate the domestic waste mixed with glass. Although the shape of the inc...
