Embodiment 1

[0027] The method for preparing ceramic wall tiles by utilizing industrial waste slag of aluminum profiles comprises the following steps:

[0028] (1) Take 20kg of industrial waste residue from an aluminum profile factory in South China and dry it at 150°C, then calcinate it in a high-temperature furnace at 1000°C (hold for 1 hour, the heating rate during calcination is 500°C per hour, directly from room temperature to calcination temperature), after natural cooling, the aluminum profile industrial waste slag clinker is obtained; then the clinker is ball milled, the ball milling time is 60min, the pulp is passed through a 80 mesh sieve, and after drying, it is granulated through a 20 mesh sieve to obtain the aluminum waste slag clinker , to be batched; the chemical composition of aluminum waste slag in the present embodiment is shown in Table 1.

Embodiment 2

[0040] The difference between this embodiment and Example 1 is that aluminum profile industrial waste clinker: light white material: carboxymethyl cellulose (CMC): sodium tripolyphosphate (STPP) = 20: 80: 0.1: 0.3; firing The time heating system is as follows:

[0041]From room temperature to 500°C within 15 minutes, from 500°C to 800°C within 15 minutes; from 800°C to 1000°C within 20 minutes; from 1000°C to 1100°C within 25 minutes; from 1100°C within 5 minutes To 1140°C; keep at 1140°C for 25 minutes.

[0042] The lightweight material obtained in this embodiment has good surface effect and a specific gravity of 1.39g / cm 3 , the flexural strength (modulus of rupture) is 21.4MPa, the thermal conductivity is 0.5236 (W / mK), and the water absorption rate is 0.29%. (10-11MPa), the strengthening effect of aluminum waste slag is obvious.

Embodiment 3

[0044] The difference between this embodiment and Example 1 is that aluminum profile industrial waste clinker: light white material: carboxymethyl cellulose (CMC): sodium tripolyphosphate (STPP)=25: 75: 0.1: 0.3; The time heating system is as follows:

[0045] From room temperature to 500°C within 15 minutes, from 500°C to 800°C within 15 minutes; from 800°C to 1000°C within 20 minutes; from 1000°C to 1100°C within 30 minutes; from 1100°C within 5 minutes To 1140°C; keep warm at 1140°C for 30min.

[0046] The lightweight material obtained in this embodiment has good surface effect and a specific gravity of 1.41g / cm 3 , the flexural strength (modulus of rupture) is 20.3MPa, the thermal conductivity is 0.7246 (W / mK), and the water absorption rate is 0.36%. (10-11MPa), the strengthening effect of aluminum waste slag is obvious.

Abstract

The invention discloses a ceramic wall tile prepared from aluminum profile industrial residues and a preparation method thereof. The method comprises the following steps: pretreating aluminum profile industrial residues; proportioning raw materials of a high-strength light-weight ceramic wall tile: mixing and proportioning aluminum waste residue clinker, light-weight white material, carboxymethyl cellulose and sodium tripolyphosphate according to a ratio of (5-30):(70-95):0.1:0.3, then performing ball milling, blending, pulping, sieving with a 80-100-mesh sieve, drying, sieving with a 20-30-mesh sieve, and granulating: molding the high-strength light-weight ceramic wall tile; and sintering the high-strength light-weight ceramic wall tile, thus obtaining the high-strength light-weight ceramic wall tile. Compared with a light-weight ceramic wall tile formula containing no aluminum waste residues, the folding strength of the material is obviously improved, and is increased almost twice in comparison with the Chinese standard; and through the introduction of the aluminum waste residues into the production of the light-weight ceramic wall tile, the property of the material is enhanced, the production cost is lowered, a large number of waste residues can be treated for the society, and the environment can be protected.

Description

technical field [0001] The invention relates to a ceramic wall brick, in particular to a method for preparing a high-strength light ceramic wall brick by utilizing industrial waste residue of aluminum profiles. Background technique [0002] At present, the treatment methods of industrial waste slag from aluminum profile factories in my country are still relatively backward, mainly for agricultural use and simple landfill, which not only seriously affects the normal production of aluminum factories, causes secondary pollution, but also occupies a large amount of land, and makes many of the waste slag Useful chemical components are lost and wasted, so the treatment and comprehensive utilization of industrial waste residue in aluminum profile factories is very important. According to statistics, an alumina coloring line with an annual production of 20,000 tons of aluminum profiles produces about 600 tons of sludge and 15,000 tons of waste residue per year. In 2011 The annual nati...
