Embodiment 1

[0039] raw material:

[0040] Phosphogypsum 50kg, fiber 1kg, cement 6kg, yellow phosphorus slag 20kg and quicklime 2kg.

[0041] Preparation:

[0042] Put yellow phosphorus slag, cement, fiber, quicklime and phosphogypsum into the mixer, stir and react for 10 hours at a temperature of 80°C and a stirring speed of 3000r / min, then grind it into a fine powder of 80 meshes, and add the mixture to the obtained mixed material After the water with 12% weight of the material is stirred evenly, it is poured into the mold, and the formed phosphogypsum substrate is sent to a curing room with a temperature of 128°C and a pressure of 0.3MPa for 12 hours; After drying to a moisture content of 4%, the surface of the substrate is repaired and sanded to a flatness of 2mm, and the surface of the substrate is coated with polyester oil paint white paint with a thickness of 0.5mm. Dry it for 18 hours, and then spray the granite topcoat with a thickness of 2mm. After the granite topcoat is natura...

[0045] raw material:

[0046] Phosphogypsum 80kg, fiber 2kg, cement 16kg, yellow phosphorus slag 30kg and quicklime 10kg.

[0047] Preparation:

[0048] Put yellow phosphorus slag, cement, fiber, quicklime and phosphogypsum into the mixer, stir and react for 8 hours at a temperature of 90°C and a stirring speed of 3500r / min, then grind it into a 100-mesh fine powder, and add the obtained mixed material to the mixed material After the water with 16% weight is stirred evenly, it is poured into the mold, and the formed phosphogypsum substrate is sent to a curing room with a temperature of 132°C and a pressure of 0.3MPa for 12 hours; After drying to a moisture content of 6%, the surface of the substrate is repaired and sanded until its flatness is less than 2mm, and the surface of the substrate is coated with polyester oil paint white paint with a thickness of 1mm, and dried at a temperature of 60°C Treat for 15 hours, and then spray the granite topcoat with a thickness of 1mm. ...

Embodiment 3

[0051] raw material:

[0052] Phosphogypsum 60kg, fiber 1.2kg, cement 10kg, yellow phosphorus slag 22kg and quicklime 4kg.

[0053] Preparation:

[0054] Put yellow phosphorus slag, cement, fiber, quicklime and phosphogypsum into the mixer, stir and react for 9 hours at a temperature of 82°C and a stirring speed of 3100r / min, then grind it into a fine powder of 80 meshes, and add the obtained mixed material to the mixed material After mixing 13% water by weight evenly, pour it into the mold, send the formed phosphogypsum substrate into a curing room with a temperature of 129°C and a pressure of 0.3MPa for 15 hours, and wait for the phosphogypsum substrate to cool at room temperature. After drying to a moisture content of 5%, the surface of the substrate is repaired and sanded until its flatness is less than 2mm, and the surface of the substrate is coated with polyester oil paint white paint with a thickness of 0.9mm, at a temperature of 52°C Dry for 16 hours, and then spray ...

Abstract

The invention discloses a granite-imitation wall body material and a preparation method thereof. The granite-imitation wall body material is prepared from following raw materials, by weight: 50-80 parts of phosphogypsum, 6-16 parts of cement, 1-2 parts of fibers, 20-30 parts of yellow phosphorus furnace slag and 2-10 parts of quick lime. In the invention, by means of the phosphogypsum, the yellow phosphorus furnace slag and the quick lime as raw materials for preparing the granite-imitation wall body material, a problem that the waste phosphogypsum is stacked just like mountains can be solved. The invention has an important significance on environment protection and sustainable development. The wall body material is light in weight, is good in water and fire resistance, is high in compressive strength and is strong in weather resistance, and can be widely used as an indoor / outdoor decorative material.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a granite imitation wall material 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 fillin...
