Abstract

The invention discloses a granite-imitation floor tile and a preparation method thereof. The granite-imitation floor tile includes following raw materials, by weight: 50-70 parts of phosphogypsum, 10-20 parts of fly ash, 20-40 parts of yellow phosphorus furnace slag and 1-5 parts of quick lime. The preparation method includes following steps: (1) feeding the yellow phosphorus furnace slag, the phosphogypsum, the fly ash and the quick lime into a stirring machine and stirring the raw material to perform a reaction for a certain time; (2) grinding the product mixture into fine powder and naturally aging the fine powder; (3) mixing the aged fine powder with water to obtain a mixture, and pouring the mixture into a die to form a phosphogypsum base material; and (4) performing maintenance to the phosphogypsum base material and finally performing spraying on the phosphogypsum base material to obtain the granite-imitation floor tile. In the invention, by means of the phosphogypsum as the main raw material to prepare the granite-imitation floor tile, a problem that the waste phosphogypsum is stacked just like mountains can be solved since the market demand of the floor tile is large, so that the invention has an important significance on environment protection and sustainable development.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a granite-like floor tile and a preparation method thereof. Background technique [0002] In the phosphoric acid production process, every ton of P produced 2 o 5 Five tons of phosphogypsum are produced by-product, and the annual by-production of phosphogypsum by medium-sized phosphoric acid production enterprises is about 3.5 million tons. So much phosphogypsum not only requires a large slag dump, but also causes water pollution. At present, the most commonly used phosphogypsum treatment methods are as follows: [0003] The first method: Phosphoric acid paste is used to backfill the pit. According to statistics, when phosphogypsum is not used to backfill the mine shaft, the filling cost of the mine shaft accounts for 1 / 3 of the mining, and the filling material accounts for 80% of the filling cost. If phosphogypsum is used to fill the mine shaft, the filling cost i...
