Embodiment 1

[0037] This embodiment provides a method for preparing a sintered permeable brick prepared from ceramic waste as the main material, which includes the following steps:

[0038] (1) 40 parts of ceramic waste, 55 parts of ceramic polishing slag and 5 parts of kaolin are mixed with water to obtain a mixture, and the water content of the mixture is controlled at 12%;

[0039] (2) Move the mixture processed in step (1) to a hydraulic brick press, and press it in a forming mold with a forming pressure of 15MPa to obtain a permeable brick body. Different molds can obtain permeable bricks of different shapes and sizes ;

[0040](3) In order to avoid cracking during the sintering process, the permeable brick body obtained in step (2) is dried naturally or at 100°C, so that the water content of the permeable brick body is 2%;

[0041] (4) Move the permeable brick body treated in step (3) to the kiln for sintering, raise the furnace temperature to 500°C at a heating rate of 5°C / min, kee...

Embodiment 2

[0043] This embodiment provides a method for preparing sintered permeable bricks prepared from ceramic waste as the main material. The specific steps are the same as in Embodiment 1, the only difference being:

[0044] In step (1), 50 parts of ceramic waste, 40 parts of ceramic polishing slag and 10 parts of kaolin;

[0045] In step (2), the molding pressure is 20MPa;

[0046] In step (4), the highest sintering temperature is 1200°C.

Embodiment 3

[0048] This embodiment provides a method for preparing sintered permeable bricks prepared from ceramic waste as the main material. The specific steps are the same as in Embodiment 1, the only difference being:

[0049] In step (1), 60 parts of ceramic waste, 25 parts of ceramic polishing slag and 15 parts of kaolin;

[0050] In step (4), the highest sintering temperature is 1250°C.

Abstract

The invention belongs to the technical field of building materials and in particular relates to a sintered water permeable brick prepared by taking a ceramic waste material as a main material and a preparation method thereof. The sintered water permeable brick is prepared from the following raw materials in parts by weight: 40 to 60 parts of the ceramic waste material, 25 to 55 parts of ceramic polishing dreg and 5 to 15 parts of kaolin. The preparation method of the sintered water permeable brick comprises the following steps: (1) adding water and mixing the ceramic waste material, the ceramic polishing dreg and the kaolin to obtain a mixture; (2) transferring the mixture treated by the step (1) into a brick pressing machine, and pressing and molding to form a water permeable brick blank; (3) drying the water permeable brick blank obtained by the step (2) to control the moisture content of the water permeable brick blank to be lower than 3 percent; (4) transferring the water permeable brick blank treated by the step (3) into a kiln and sintering; cooling to room temperature along the kiln to obtain the sintered water permeable brick. The water permeable brick is simple in composition and low in cost; the preparation method is simple and the problems that the comprehensive utilization efficiency of the ceramic waste material is low and the environment is polluted are solved.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a sintered permeable brick prepared from ceramic waste as a main material and a preparation method thereof. Background technique [0002] my country's architectural ceramics industry has developed rapidly. With the increase of production, the amount of ceramic waste, especially polished brick waste, is increasing. According to statistics: only Foshan ceramic production area, the annual output of various polished brick waste has exceeded 6 million tons (the total amount of ceramic waste is estimated to be 100,000 tons), and the annual output of polished brick waste in the country is estimated to be around 10 million tons (the total amount of ceramic waste is estimated to be 20 million tons). Such a large amount of ceramic waste can no longer be solved by simple landfill methods. A large amount of accumulated ceramic waste occupies land, seriously damages the ecological e...
